Description

【００８６】
このように運転モードと室内環境情報および電力会社からのデマンド要求レベルに応じて、デマンド制御装置により空気調和機のデマンド運転モード、特に、設定温度を決定することにより、利用者の快適性を考慮した空気調和機のデマンド制御を行うことができる。
【００８７】
また、室外環境（温度や太陽光など）も、室内空調環境側に対して空調負荷となり、例えば、室内温度２７℃が同じ状況でも室外温度２８℃と３２℃の場合で表２の設定例４、５のようにデマンド要求レベル２における設定温度に差を設けてもよい。
さらに表３の設定例６、７のようにデマンド要求レベル２において昼夜の差を設けてもよい。

さらに、室内外環境検出手段を用いて、快適度ＰＭＶを算出して設定温度を変更してもよい。ここで簡単にＰＭＶについて簡単に説明する。ＰＭＶは快適方程式に基づいて導出され、たとえば−３なら寒い，−２なら涼しい…，＋３なら暑いという風に温熱感覚が数値で表される。この快適方程式は複雑なため、これを簡単に記すと、
ＰＭＶ＝ｆ（温度，輻射温度，湿度，気流，着衣量，代謝量）
となる。ＰＭＶを算出するための６要素うち、大きな影響を与えるものは、温度及び輻射温度であり、この２要素によって、ＰＭＶを推定することが可能である。ＰＭＶの変化を０．５程度生じさせるためには、温度だけなら約２〜３℃、輻射温度だけなら約５℃の変化が必要である。
【００９１】
一般的に、人間が温熱感の変化を感じるためにはＰＭＶで０．５程度の変化が必要である。したがって、デマンド制御装置に室温検出手段と輻射温度検出手段を具備することにより、室内の代表ＰＭＶに基づいた空気調和機の運転制御が可能となる。この室内の代表ＰＭＶに基づいて空気調和機の運転モードや設定温度を変更することにより、不快感を与えないデマンド制御が可能となる。
【００９２】
さらに、図２５のような熱画像検出装置をデマンド制御装置の室内外環境検出の一手段として用いてもよい。この熱画像検出装置によると、１次元に８素子並べられた焦電素子６８を水平方向に駆動することにより、縦８×横６４画素の室内の温度分布を検出することが可能である。つまり、図２６のように熱画像検出装置６９をデマンド制御装置６０に付加し、空気調和機に対して設置することにより、温度検出部７０（斜線部）を室内全体に対して適応すると室内全体の温度分布（熱画像）の測定が可能となる。また、この熱画像検出装置６９は、熱画像の特徴点検出から人体の判別や人体位置７１の特定できるため、気流７２の影響を考慮した人体位置でのＰＭＶによる空気調和機の温度設定のみならず風向や風量による気流感を含めたデマンド運転モードによる空気調和機のデマンド制御が可能となる。
【００９３】
加えて、人体位置でのＰＭＶを０．５程度変更させるとした時、設定温度のみでデマンド制御を行う場合に比べて、快適方程式に気流感を導入できることにより、圧縮機の回転周波数を１ランクダウンできる可能性があり、より効率的な空気調和機のデマンド制御と快適性の両立が可能となる。
【００９４】
（１９）第１９実施形態：
図２７（ａ），（ｂ）はそれぞれ夏冬の標準条件における空気調和機の運転開始から室内温度変化を示したものである。室内の温度が安定するまでに夏では３０分以上、冬では約９０分以上を要し、この間は利用者にとって快適とはいえない室内環境である。こうした状況の中で電力会社の電力ピークカットを行うためのデマンド要求情報により設定温度が大きく変更されると安定時に利用者の意志とは大きくずれた室内環境となる。
【００９５】
また、デマンド制御装置は空気調和機とは独立して存在するため、空気調和機の運転状態は不明である。
したがって、デマンド制御装置は室内環境を把握する必要がある。
例えば、図２７（ａ）の場合、夏期においては空気調和機の運転開始から３０分間を過渡状態、それ以後を安定状態とする。また、冬季には同じく運転開始から９０分間を過渡状態、それ以後を安定状態とする。
【００９６】
さらに、室内環境検出手段により、室内温度や快適度ＰＭＶの時間変化を得て、室内環境の過渡状態あるいは安定状態を判定することもできる。
【００９７】
（２０）第２０実施形態：
図２７（ａ），（ｂ）のように空気調和機が過渡状態７３にある場合、圧縮機の回転周波数は最大周波数であり、設定温度３℃程度変更しても消費電力の低減につながらないばかりか、この時点で設定温度の変更を行った場合、安定状態に至った場合、利用者の快適性も大きく損なわれる。また、過渡状態１６のような場合には、表１の設定例１のような状態であり、圧縮機の周波数制御可能な範囲にはあるが室内の熱バランスの関係から室内環境が十分安定しているとはいえない。したがって、空気調和機の運転あるいは室内空調環境が過渡状態にある場合には設定温度を頻繁に変更しても消費電力の低減に結びつかないし、利用者の快適性も得られない。
【００９８】
このような過渡状態７３，７４では、ワイヤレスリモコン６４からの（利用者の希望する）空気調和機の運転モード情報とデマンド要求レベルに応じて、１回だけデマンド運転モードの内容を変更することとし、過渡状態中にさらに、デマンド要求レベルが変更されても、このデマンド要求レベルに対するデマンド運転モードの内容を空気調和機に対して送信しないこととする。また、この間にデマンド制御装置が受け付けたデマンド要求レベルに対するデマンド運転モードは安定状態７５に移行した時にデマンド制御装置の送信部から空気調和機に対して送信される。
【００９９】
（２１）第２１実施形態：
デマンド制御装置が室内環境が安定状態７５とした場合、室内温度あるいはＰＭＶの変化に応じて、デマンド制御開始時の圧縮機の運転周波数を越えない範囲、あるいは消費電力内でデマンド運転モードを１回以上変更する。図２８は室内環境が冷房安定時において、デマンド制御中、デマンド制御装置により設定温度変更７８を複数回行った場合の室温７６と消費電力７７の時間変化を示したものである。デマンド制御開始時の消費電力７７'を越えない範囲で設定温度を変更することで、快適性とデマンド制御の両立が可能となる。
【０１００】
図２９は（実施形態１８）から（実施形態２１）の空気調和機のデマンド制御方法を簡単にフローチャートとして示したものである。
デマンド制御装置６０は、ステップ１０１に示すように室内外環境情報や空気調和機の運転開始経過時間を計測し、ステップ１０６の室内環境状態の判定に用いられる。
デマンド要求受信後（ステップ１０２）、現状の室内外環境，現状の運転モードや電力会社からのデマンド要求情報に基づいて、デマンド制御中の空気調和機のデマンド運転モードが決定され（ステップ１０４）、決定されたデマンド運転モードがデマンド制御装置６０のワイヤレスリモコンの送信部６５から空気調和機に対して送信される（ステップ１０５）。
室内環境が安定状態の場合には、任意の時間経過後、室内外環境情報に基づいて、空気調和機の運転モードを変更してもよい。
【０１０１】
（２２）第２２実施形態：
デマンド制御終了時、図３０（ａ），（ｂ）はそれぞれデマンド制御終了時点からの消費電力の時間変化とデマンド制御装置による運転モード（設定温度に限る）の変更を示したものである。図７（ｂ）の点線７９'のように設定温度をデマンド制御開始時点の運転モードに一気に戻す場合、図３０（ａ）の点線８０'のように消費電力は一気に増加する。発電所を含む電力系統には各家庭の相当多数の空気調和機が接続されているため、デマンド制御終了時に再び電力ピークカットが必要な状況に陥る可能性がある。したがって、図３０（ａ）の実線８０のようにデマンド要求によって、変更された設定温度を段階的にデマンド制御開始時まで変更７９することによって、積算消費電力は一気に設定を変更した場合とほとんど変わらないが、瞬間的な電力ピークの発生を抑制し、発電所のオーバーロードによる地域の停電などの事態を防ぐことができる。
【０１０２】
図３１は、デマンド制御終了時の空気調和機の設定温度変更を簡易的にフローチャートに示したものである。デマンド制御終了時（ステップ１０７）に、設定温度をデマンド制御開始以前の設定温度（ステップ１０９）まで段階的に時間をかけて変更していく。
【０１０３】
また、デマンド制御終了時、デマンド制御開始時とは室内外環境は変化しており、デマンド制御装置の室内外環境情報にもとづいて、前記デマンド制御装置の演算部で求められた運転モードに変更してもよい。ただし、この場合も前述の理由により段階的に運転モードを変更していく必要がある。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an air conditioner for cutting a peak of an electric power load due to an increase in electric power demand in summer or the like and for equalizing the electric power load. The present invention also uses an existing air conditioner that can be controlled by a wireless remote control using a communication network.Electric powerThe present invention relates to a control device of an air conditioner for performing control. The present invention further provides a wireless remote control type existing air conditioner for general household use in response to a request from a power company without impairing comfort.handPerform power control,The present invention relates to a control method and a control device for an air conditioner.
[0002]
[Prior art]
As a power situation in recent years, there has been a problem in that the amount of power used during a very hot summer season approaches a supply limit due to a large increase. It is known that one of the causes is due to the use of air conditioners in homes, offices, and factories. Therefore, the power consumption of the air conditioners is reduced according to an increase in power consumption.Electric powerThe demand for control is increasing. More recently, the growing tendency to rely on electric heating meansElectric powerThe need for control has also been talked about.
Air conditionerElectric powerAs a method for performing the control, a method using a Japanese Industrial Association standard HA terminal (JEM-A) is simple. From outsideElectric powerPerforming ON / OFF control according to a control command can be relatively easily performed for an air conditioner having an HA terminal.
SaidElectric powerAn example of an air conditioner control device that performs control will be described with reference to the drawings.
As shown in FIG. 4, reference numeral 1001 denotes an air conditioner, which includes an operation state detection device 1002 such as an HA terminal (JEM-A terminal) (compliant with JEMA standards) provided on the air conditioner 1001, an operation signal output device 1003, The operation signal computing device 1004 and the power control signal receiving device 1005 are connected via a communication line 1006 composed of a twisted pair wire or the like. The transmission line 1007 is formed by a power line or an optical fiber cable, and connects the power control signal receiving device 1005 and the external power supply source 1008.
[0003]
The power load leveling method of the air conditioner remote control device configured as described above will be described.
For example, when a power load reaches a peak in an external power supply 1008 such as a power company at a time when the power consumption reaches a peak in summer or the like, a power control signal for suppressing power consumption is transmitted via a transmission line 1007 to an external device. The power control signal is received by the power control signal receiving device 1005 from the power supply source 1008. A command to stop the operation of the air conditioner 1001 is calculated by the operation signal calculation device 1004 based on the power control signal received by the power control signal reception device 1005, and the calculated operation stop command is output via the communication line 1006. It is output from the device 1003 to the operation state detection device 1002. The air conditioner 1001 stops the operation after receiving the operation stop command from the operation state detection device 1002, and restarts the operation again after a certain period of time. By repeating the above series of controls, the power consumption of the air conditioner 1001 is suppressed. Further, the power suppression amount is adjusted by changing the operation stop time or changing the number of times of switching between operation and stop. These controls are performed until the peak of the power load has passed.
[0004]
Next, FIG. 5 shows a circuit diagram for detecting the indoor suction temperature of the air conditioner.
One end of a thermocouple (thermistor) 1009 is connected to a constant potential, and a switch 1011 is connected between the other end of the thermocouple 1009 and the resistor 1010. A plurality of switches 1011a to 1011e and series circuits of resistors 1012a to 1012e are connected in parallel to the switch 1011 in a plurality of stages. The resistors 1012a to 1012e have different resistance values. One end of a capacitor 1014 and an indoor suction temperature calculating device 1015 are connected to a connection point 1013 between the switch 1011 and the resistor 1010, and the other ends of the resistor 1010 and the capacitor 1014 are connected to an earth.
[0005]
A method for leveling the power load of the circuit for detecting the indoor suction temperature of the air conditioner configured as described above will be described.
In FIG. 5, a dotted line indicates a circuit for detecting the indoor suction temperature of a normal air conditioner.
The resistance value of the thermocouple 1009 changes according to the indoor suction temperature, and the potential at the point 1013 in FIG. 5 changes accordingly. The indoor suction temperature calculating device 1015 calculates the indoor suction temperature from the potential at the point 1013. As a result, when the indoor suction temperature reaches the set temperature, the operation of the air conditioner is settled down to a steady state, and the power consumption is reduced. The above is the operation control method of the ordinary air conditioner. In FIG. 5, a series circuit of switches 1011a to 1011e and resistors 1012a to 1012e is connected in a plurality of stages in parallel with the switch 1011. By switching these switches 1011 and 1011a to 1011e, the potential of the point 1013 is changed to a normal potential. The potential can be set lower than the potential at the position corresponding to the point 1013 in the circuit of the air conditioner.
That is, although the indoor suction temperature has not actually reached the set temperature, the indoor suction temperature calculation device 1015 appears to have reached the set temperature, and the operation of the air conditioner has been reduced to a steady state. And reduce power consumption. By appropriately switching the switches 1011 and 1011a to 1011e, the temperature difference from the actual indoor suction temperature is adjusted to adjust the amount of power consumption suppression.
[0006]
However, in the above-described configuration, the operation state detection device 1002 such as a JEM-A terminal (based on the JEMA standard) can only operate and stop the air conditioner 1001. Had the problem of spoiling
[0007]
In addition, in order to level the power load of an existing air conditioner by temperature control, there was a problem that the main body of the air conditioner had to be remodeled.
[0008]
Further, the HA terminal is a standard for realizing control and state management between two values of ON / OFF, and the contents of control and state management are limited. Therefore, it is difficult to finely control the temperature change in the room, and comfort is greatly sacrificed. In the case of an inverter-type air conditioner with variable compressor capacity, when the difference between room temperature and the set temperature is large, control to increase the capacity is generally performed. May be larger than
[0009]
Therefore, by controlling the temperature set value instead of simply turning on / off the entire air conditioner as described above, comfort is not impaired as much as possible, and instantaneous power consumption is conversely increased. A method without the above is disclosed in Japanese Patent Application Laid-Open No. 1-114654. This is configured as shown in FIG. The air conditioner 1020 includes a load control device 1021, a communication control unit 1022 for controlling communication with the outside, an air conditioner control unit 1023 for controlling operation / stop of the air conditioner, and a temperature sensor 1027. The communication control unit 1022 monitors the amount of power used by the power meter 1024 andElectric powerIssue a control commandElectric powerThe monitoring device 1025 is connected to the transmission line 1026.
[0010]
With the increase in power consumptionElectric powerFrom the monitoring deviceElectric powerWhen a control command is issued, it is input to the communication control unit through the transmission line.Electric powerBy shifting the temperature setting of the air conditioner from the contents of the control command and the value of the temperature sensor of the air conditionerElectric powerPerform control.
[0011]
However, in the configuration of FIG. 23, since the temperature set value of the air conditioner is directly controlled, the function of the load control device must be built in the air conditioner in advance. If the existing air conditioner does not have the function of the load control deviceElectric powerIf control is to be performed, remodeling is necessary, and the cost and labor involved in the modification are serious problems. Therefore, the existing air conditionerElectric powerThere was a need for a way to control.
[0012]
Next, in Japanese Patent Application Laid-Open No. 2-115644, as shown in FIGS. 32 (a) and 32 (b), a plurality of air conditioners are supplied to the house wiring within the range of the breaker capacity installed in the house. Based on the total load current value (FIG. 32 (a)), the comfort is increased by performing forced thermo-off (compressor stop) or driving the compressor at the lowest operation frequency (FIG. 32 (b)) from the lowest priority. A method of performing demand (power load) control without loss is disclosed.
[0013]
In addition, demand control by operating or stopping the air conditioner 1032 according to information from the communication network 1031 using the HA terminal (JEM-A) and the HA terminal 1030 as shown in FIG. Was also possible.
[0014]
Further, Japanese Patent Application Laid-Open No. 1-1114654 discloses a demand control device for a plurality of air conditioners, in which a set temperature of the air conditioner is shifted by 1 ° C. in a direction of decreasing the amount of power when a contract power is exceeded. ing.
[0015]
FIG. 34 is a demand operation operation chart during cooling. According to this, when the electric energy of the air conditioner exceeds the upper limit specified value, the set temperature of the operating air conditioner (t₀If the power amount does not become equal to or less than the upper limit specified value after a lapse of a predetermined time, the control for further increasing the set temperature by one degree is repeated (t)._Two, T_ThreeBy setting the time, the difference between the indoor temperature and the set temperature is reduced, and the demand control can be performed by repeating the ON / OFF operation of the compressor by the indoor control function.
[0016]
Japanese Patent Application Laid-Open No. 143670/1995 discloses a demand control device that restricts the use of electric power when a power consumption value is about to exceed a contract power value in a system to which a power load including an air conditioner is connected. ing. As shown in FIG. 35, the demand control device performs demand (power load) control that does not impair comfort by optimally allocating the power amount based on the power consumption in the system, the indoor / outdoor temperature, and the like, in accordance with the excess power. Is what you do.
[0017]
Next, an operation control method of a general household air conditioner will be briefly described. FIG. 36 is a block diagram of a general household air conditioner, in which a user's intention (operation mode) is transmitted to an air conditioner 1041 via a wireless remote controller 1040, and the arithmetic processing unit of the air conditioner 1041. Operating modes such as cooling, heating, airflow, airflow, and set temperature are determined. Based on this operation mode, the operation of the blower and the compressor of the indoor / outdoor unit is controlled. Generally, the operation control of the compressor of the air conditioner is performed by setting the temperature from the wireless remote controller 1040 and the suction (to the air conditioner). This is based on the difference in the air temperature.
[0018]
FIG. 37 shows the relationship between the power consumption and the compressor operating frequency of an inverter variable speed type general household air conditioner. It can be seen that as the operating frequency of the compressor increases, A → B →..., The power consumption also increases. FIG. 38 (a) shows a relationship between a set temperature, a suction temperature difference, and a compressor operating frequency of the inverter variable speed type general home air conditioner at the time of cooling, and FIG. Similarly, it shows a relationship between a set temperature at the time of heating, a suction temperature difference, and a compressor operating frequency.
[0019]
At the time of cooling and heating, the operating frequency of the compressor of A, B,... In FIG. 37 is assigned to the air conditioner according to the difference between the set temperature and the suction temperature. As can be seen from FIGS. 37 and 38, by increasing the set temperature of the air conditioner at the time of cooling, the operating frequency of the compressor decreases from D to C to B to A, and power consumption can be reduced. Become. Similarly, during heating, power consumption can be reduced by lowering the set temperature.
[0020]
A so-called constant-speed type air conditioner in which a compressor is directly driven by a commercial power supply stops the compressor when the suction temperature falls below a set temperature (thermo OFF) as shown in FIG. Then, the compressor is restarted (thermo ON) to control the indoor temperature. In this case, by changing the set temperature, demand control of the air conditioner can be realized by ON-OFF operation of the compressor.
[0021]
However, in the above-described conventional configuration, the start / stop of the general home air conditioner and the lowest frequency drive of the compressor are performed irrespective of the indoor and outdoor environmental conditions. When the operation mode is changed, the comfort of the user is impaired, the probability that the demand control is canceled increases, and it is difficult to perform effective power peak cut.
[0022]
In a demand control device that reduces the power of an air conditioner so as not to exceed a contracted amount of power in a system to which a power load including an air conditioner is connected, an ON / OFF cycle or a plurality of air conditioners may be used. There was also a problem that comfort was inevitably worsened to disperse the electric power.
[0023]
Large power consumers such as buildings and factories that exchange contract power values with power companies centrally control (control) multiple air conditioners, and monitor the power usage status and indoor environment status of each air conditioner. It is relatively easy to grasp, but since general household air conditioners exist independently, it is difficult to obtain the operating status and information of the air conditioner using centralized management and other devices. Had.
[0024]
In addition, in recent years, air conditioners for general household use have become remarkably widespread as air conditioners that are safe and clean throughout the year, and accordingly, the power consumption in winter has been remarkably increasing regardless of summer. Along with this, power demand leveling and power peak cut have become a real social problem.
[0025]
In particular, the peak power cut can be realized by gradually reducing the power consumption of each household, and it is possible to prevent a local power outage accident due to overload of the power plant. Momentum of demand control for large air conditioners is increasing. In order to efficiently perform demand control of an air conditioner in a general home, it is the most important issue to reduce the cancellation rate of the demand control by minimizing deterioration of the comfort of the indoor environment.
[0026]
Furthermore, in the past, in limited power systems such as homes, factories and buildings,Electric powerThere is no problem if control is in place, but large-scaleElectric powerWhen control is performed,Electric powerAt the end of control, change the operation mode of the air conditioner.Electric powerIf you change all the way to the setting at the start of control, the power load in the area will suddenly increase,Electric powerThere is a possibility that the situation requiring control may be repeated.
[0027]
The present invention solves the above-mentioned problems, and aims to equalize the power load at the time of the power load peak without modifying the existing air conditioner main body and without impairing the comfort of the customer. It is the purpose.
[0028]
The present invention also enables a wireless remote control type air conditioner to be effectively used in a simple manner without impairing comfort as much as possible.Electric powerIt is another object to provide a control device of an air conditioner for controlling.
[0029]
The present invention further provides a wireless remote control type air conditioner.Electric powerControl method andElectric powerIt is another object to provide a control device.
[0030]
[Means for Solving the Problems]
The present invention has been made to achieve the above object. In the following description, the expressions “power control” and “demand control” may be used as appropriate, but in that case, both mean the same in content.

BEST MODE FOR CARRYING OUT THE INVENTION
In the following description, an example in which the demand control system is performed during cooling in the summer will be described. However, the method is the same for the heating in the winter except for the shift direction of the set temperature, which is different.
(1) First embodiment:
In addition, the same portions and corresponding portions in each embodiment are denoted by the same reference numerals, and description thereof is omitted. In the demand control system for an air conditioner shown in FIG. 1, an air conditioner 10, an operation setting device 11, such as a remote controller, an indoor environment detection device 12, a power control signal receiving device 13, an operation control set value calculation device 14, and an operation control signal An output device 15 is provided, and each device except the air conditioner 10 is connected via a communication line 16 composed of a twisted pair wire or the like. The transmission line 17 is composed of a power line or an optical fiber cable, and connects the power control signal receiving device 13 to an external power supply source 18.
[0040]
The power load leveling method for the demand control system for an air conditioner configured as described above will be described. For example, when the power load reaches a peak in an external power supply source 18 such as a power company at a time when the power consumption reaches a peak in summer or the like, a power control signal for suppressing power consumption is transmitted via a transmission line 17. The power control signal is received by the power control signal receiving device 13. Based on indoor environment information such as the presence / absence or number of persons in the room detected by the indoor environment detecting device 12 and the power control signal received by the power control signal receiving device 13, the air conditioner 10 is operated in the operation control set value calculating device 14. An operation control set value such as a start / stop setting, a temperature setting, or an air volume setting for the is calculated. The calculated operation control set value is output from the operation control signal output device 15 to the air conditioner 10 as an operation control signal to the air conditioner 10 as a signal having the same format as a wireless signal such as an infrared signal output from the operation setting device 11. In accordance with the control signal, the air conditioner 10 changes the operation setting such as the operation / stop setting, the temperature setting, or the air volume setting to a state in which the power consumption is reduced, and after a certain period of time, operates again with the original operation setting value. By repeating the above control, the power consumption of the air conditioner 10 is suppressed. The amount of suppression of power consumption is adjusted by changing the content of change of the operation set value, the time for changing the operation setting and performing the power saving control, or the number of times of performing the power saving control.
These controls are performed for each air conditioner until the peak of the power load has passed, and as a result, the power load is leveled.

In the embodiment of FIG. 1, the indoor environment detecting device 12, the power control signal receiving device 13, the operation control set value calculating device 14, and the operation control signal output device 15 are provided independently, respectively. The effect is the same even when any device is integrated or when all devices are integrated.
[0042]
(2) Second embodiment:
The demand control system according to the second embodiment shown in FIG. 2 includes a timer 20, and the timer 20 and the exercise control set value calculation device 14 are connected by a communication line 16.
[0043]
Regarding this demand control system for an air conditioner, a method of leveling the power load will be described. When the power load reaches a peak in the external power supply 18 at a time when the power consumption reaches a peak in summer or the like, a power control signal for suppressing power consumption is transmitted via the transmission line 17 to the power control signal receiving device. 13 is received. In addition, the absence state of a person is detected by the indoor environment information detection device 12, and the absence time is integrated by the timer device 20. When the integrated value obtained by the timer device 20 becomes equal to or more than a predetermined value, the second operation control set value calculation device 14 generates an operation control signal for stopping the operation of the air conditioner 10 by assuming that the person is out of the vehicle, and the operation control signal output device 15 Output. Thereby, the operation of the air conditioner 10 is stopped, so that unnecessary power consumption due to forgetting to turn off the air conditioner 10 when going out can be eliminated, and power saving control for another room or a customer's air conditioner can be performed. Of the operation setting can be relaxed. As a result, power saving control without waste can be performed, and the power load can be leveled very effectively.
[0044]
In the embodiment of FIG. 2, the indoor environment information detecting device 12, the timer device 20, the power control signal receiving device 13, the operation control set value calculating device 14, and the operation control signal output device 15 are provided independently. Regarding the configuration of the device, the effect is the same even when any device is integrated or when all devices are integrated.
[0045]
(3) Third embodiment:
The demand control system of FIG. 3 includes a power control release signal transmitting device 21 instead of the timer.
[0046]
The power load leveling method of the air conditioner remote control device configured as described above will be described. When the power load reaches a peak in an external power supply 18 such as a power company, for example, in summer or when power consumption reaches a peak, a power control signal for suppressing power consumption is transmitted via a transmission line 17. The control signal is received by the control signal receiving device 13. The operation control set value calculating device 14 calculates the operation control set value according to the power control signal received by the power control signal receiving device 13. The calculated operation control set value is output from the operation control signal output device 15 as an operation control signal to the air conditioner 10 as a signal having the same format as a wireless signal such as an infrared signal output from the operation set value output device 11, According to this operation control signal, the operation setting of the air conditioner 10 is changed for power saving control. However, in the case of emergency such as when a person is sleeping due to illness or the like, it may be difficult for the customer to change the settings of the air conditioner 10 in some cases. In such a case, the customer can release the power saving control from the external power supply destination by operating the power control release signal transmission device 21, and it is troublesome to change the operation state of the air conditioner 10 in an emergency. In such a case, it is possible to respond.
[0047]
In the embodiment of FIG. 3, the power control signal receiving device 13, the operation control set value calculating device 14, the operation control signal output device 15, and the power control release signal transmitting device 21 are provided independently, respectively.

[0052]
An example of changing a set value when a demand control request is issued will be described with reference to FIGS. 9A and 9B. The air conditioner is in cooling operation and its set temperature is T_S0It is assumed that the reception of the wireless remote control signal has been known. As shown in FIG.₁Demand control request (level 1) is issued at time t_TwoChanged to level 2, t_ThreeIt is assumed that the request has been released.

Here, the operating state of the air conditioner is temporarily classified into four states of ABCD in the figure. At first, it is stopped (A: OFF). Immediately after the start, since there is a difference between the set temperature and the actual room temperature, the operation is performed at the maximum output (B: maximum output state). Thereafter, when the temperature approaches the set temperature to some extent, the operation capacity is gradually reduced, and accordingly, the current value is also reduced (C: transient state). Eventually, the temperature becomes substantially equal to the set temperature, and the current value does not change with directionality (D: stable state). The arithmetic processing unit estimates which state the air conditioner is in from A to D based on how the current value changes, and, based on the result and the demand level of the demand control, for example, as shown in FIG. To change. The temperature shift amounts of B and C are set smaller than the temperature shift amount of D, and the shift amounts are changed in accordance with the change of B → C → D.

The functions of the arithmetic processing unit 36, the wireless remote control signal transmitting unit 37, the wireless remote control signal receiving unit 40, and the cancel request input unit 57 are the same as those in the eleventh embodiment. When the setting of the air conditioner changes due to a remote control operation or a demand control request by the occupants, the content is transmitted from the communication control processing unit 37 to the network terminal 33. An example is shown in FIG. t₁Turns on the air conditioner (set temperature: T_S1), T_TwoTo the set temperature (T_S2), T_ThreeDemand control request (level 1, set temperature → T_S3), T_FourChange to level 2 (Set temperature → T_S4), T_FiveCancel request (Set temperature → T_S2), The control device transmits ON, set temperature, and cancel input information to the network terminal at that time as shown in the figure.
[0074]
According to the above-described embodiment, the cooperation status of the occupants with respect to the demand control (whether or not there is a cancellation input) can be known through the network, and can be reflected in the charging system. In addition, the time change of the ON / OFF of the air conditioner and the set temperature can be accumulated, and the use condition of the air conditioner can be checked through the network.
[0075]
In the present embodiment, transmission to the network terminal is performed when there is a change in the device state, but the present invention is not limited to this, and transmission is performed at regular time intervals or in response to a request from the network terminal. Has the same effect. In the present embodiment, the transmission contents are ON / OFF, set temperature, and cancel input. However, by transmitting information such as environmental information and supply current to the air conditioner, more accurate use of the air conditioner can be achieved. You can know the situation.
[0076]
(18) Eighteenth embodiment:
FIG. 24 shows the demand control system of the present embodiment.
In this system, the existing wireless remote control type air conditioner demand control device 60 is provided between a terminal of the air conditioner 61 and a communication network 62 between the power company and demand request information and demand control from the terminal and the power company. It has a communication unit 63 for exchanging operation status information of an air conditioner owned by the device, a transmission / reception unit 65 of a wireless remote controller 64, an indoor environment status detection unit 66, and an operation mode calculation unit 67.
The receiving unit 65 of the wireless remote controller of the demand control device 60 can obtain the contents of the wireless remote control operation (operation mode) of the user in the same manner as the air conditioner 61.
[0077]
Further, the demand control device 60 includes an indoor temperature sensor, a thermal image detection device, and the like as the indoor environment situation detecting means 66. Further, instead of the thermal image detection device, the presence / absence information of the person in the room may be acquired by using a representative radiation temperature in the room by a radiation sensor or a human body sensor.
[0078]
Note that the communication unit 63, the transmission / reception unit of the wireless remote controller 64, the indoor environment detection unit 66, and the operation mode calculation unit 67 are configured to be included in the demand control device, but if the demand control of the air conditioner 61 can be realized. Each device or means may exist independently.
[0079]
Further, the means for determining the air-conditioning load of the air conditioner 61 is not limited to the indoor environment information detecting means 66, and outdoor environment information may be acquired by an outdoor temperature sensor or an optical sensor.
[0080]
Therefore, the demand controller 60 for the air conditioner described above uses the demand request information from the power company, the operation mode information of the air conditioner (desired by the user) from the wireless remote controller 64, the indoor environment information, the comfort level PMV, and the like. The demand operation mode of the air conditioner 61 is determined by the operation mode calculation unit 67 based on the above, and the demand operation mode is transmitted from the wireless remote control transmission unit 65 provided in the demand control device 60 to the wireless operation of the air conditioner 61. By transmitting a signal equivalent to the transmission signal used by the remote controller 64 to the air conditioner 61, the air conditioner in the demand operation mode based on the demand request, the indoor environment desired by the user, and the current indoor environment condition. Demand control of the device 61 becomes possible.
[0081]
Table 1 shows an example in which the set temperature is changed based on the room temperature, the set temperature, and the demand request information. According to the present invention, the demand request information from the power company is provisionally set to demand request levels 1 to 3 and the request level 1 implements the power peak cut, so that the effect of suppressing the power consumption is necessarily required. The request levels 2 and 3 are information for further reducing power consumption.
[0082]
The setting example 1 is a case of cooling at a room temperature of 27 ° C. and a setting temperature of 24 ° C. There is a large difference between the indoor air conditioning environment desired by the user and the current indoor air conditioning environment.
At the demand request level 1, the effect of the demand control is necessary, and the set temperature is always changed by 1 ° C. or more. When the demand request level 2 is received, the temperature is further changed by 1 ° C. (2 ° C. from the start of the demand control). As will be described later, since a human senses a change of about 2 ° C. at room temperature, in this case, the set temperature at the demand request level 3 is not changed.
[0083]
Setting example 2 is a case of cooling at room temperature 27 ° C. and setting temperature 26 ° C. The indoor air-conditioning environment desired by the user and the actual air-conditioning environment are close to each other, and the demand level is increased by 1 ° C. at demand request levels 1 and 2, and the request level 3 Since the set temperature is changed in a direction that deteriorates the indoor air-conditioning environment from the start of the demand control, the set temperature is not changed.
[0084]
The above is an example of the temperature setting of the air conditioner by the demand control device, and a method of increasing the set temperature by 2 ° C. according to the demand request level 1 may be adopted.
However, if the set temperature is 16 ° C for cooling on a hot summer day when peak power cuts are expected, the room temperature does not actually reach 16 ° C, and the compressor of the air conditioner operates at the highest operating frequency. Therefore, demand control is impossible. In such a case, the temperature setting may be increased by about 4 ° C. at the demand request levels 1 and 2, as in Setting Example 3 of Table 1, ignoring the user's set temperature.
[0085]
[Table 1]

[0086]
In this way, the demand operation mode of the air conditioner, particularly the set temperature, is determined by the demand control device according to the operation mode, the indoor environment information, and the demand level from the power company, thereby taking into consideration the comfort of the user. Demand control of the air conditioner can be performed.
[0087]
The outdoor environment (temperature, sunlight, etc.) also becomes an air conditioning load on the indoor air conditioning environment side. For example, even if the indoor temperature is 27 ° C., the outdoor temperature is 28 ° C. and 32 ° C. 5, a difference may be provided between the set temperatures at the demand request level 2.
Further, as shown in setting examples 6 and 7 in Table 3, a difference between day and night may be provided at the demand request level 2.
[0088]
[Table 2]

[0089]
[Table 3]

[0090]
Further, the set temperature may be changed by calculating the comfort level PMV using the indoor / outdoor environment detecting means. Here, the PMV will be briefly described. The PMV is derived based on the comfort equation. For example, the sense of warmth is expressed by a numerical value such as a wind of -3 for cold, a cool of -2, and a hot of +3. The comfort equation is complex, so if you write it briefly,
PMV = f (Temperature, radiation temperature, humidity, airflow, clothing, metabolism)
It becomes. Among the six elements for calculating the PMV, those that have a great influence are the temperature and the radiation temperature, and the PMV can be estimated by these two elements. In order to cause a change in PMV of about 0.5, a change of about 2 to 3 ° C. is needed for temperature alone, and about 5 ° C. is needed for radiation temperature only.
[0091]
Generally, a change of about 0.5 in PMV is necessary for a person to feel a change in the thermal sensation. Accordingly, by providing the demand control device with the room temperature detecting means and the radiation temperature detecting means, it becomes possible to control the operation of the air conditioner based on the representative PMV in the room. By changing the operation mode and the set temperature of the air conditioner based on the representative PMV in the room, demand control that does not cause discomfort becomes possible.
[0092]
Further, a thermal image detection device as shown in FIG. 25 may be used as one means for detecting the indoor and outdoor environment of the demand control device. According to this thermal image detection device, by driving the pyroelectric elements 68 arranged one-dimensionally in the horizontal direction, it is possible to detect a temperature distribution in a room of 8 × 64 pixels. That is, as shown in FIG. 26, by adding the thermal image detection device 69 to the demand control device 60 and installing it to the air conditioner, if the temperature detection unit 70 (hatched portion) is adapted to the whole room, Of the temperature distribution (thermal image) can be measured. In addition, since the thermal image detecting device 69 can determine the human body and specify the human body position 71 from the detection of the feature points of the thermal image, if only the temperature setting of the air conditioner by the PMV at the human body position in consideration of the influence of the airflow 72, In addition, the demand control of the air conditioner can be performed in the demand operation mode including the feeling of airflow due to the wind direction and the air volume.
[0093]
In addition, when the PMV at the position of the human body is changed by about 0.5, the feeling of airflow can be introduced into the comfortable equation compared to the case where demand control is performed only at the set temperature. There is a possibility that the air conditioner can be down, and it is possible to achieve more efficient demand control and comfort of the air conditioner at the same time.
[0094]
(19) Nineteenth Embodiment:
FIGS. 27 (a) and 27 (b) show changes in indoor temperature from the start of operation of the air conditioner under standard conditions of summer and winter, respectively. It takes 30 minutes or more in summer and about 90 minutes or more in winter until the indoor temperature stabilizes. During this time, the indoor environment is not comfortable for the user. In such a situation, if the set temperature is largely changed by the demand demand information for the electric power company to perform the power peak cut, the indoor environment becomes largely deviated from the will of the user at the time of stability.
[0095]
Further, since the demand control device exists independently of the air conditioner, the operation state of the air conditioner is unknown.
Therefore, the demand control device needs to grasp the indoor environment.
For example, in the case of FIG. 27A, in the summer, a transient state is set for 30 minutes from the start of the operation of the air conditioner, and thereafter, a stable state is set. In winter, a transitional state is set for 90 minutes from the start of operation, and a stable state is set for the transitional state thereafter.
[0096]
Further, the transient state or stable state of the indoor environment can be determined by obtaining the time change of the indoor temperature and the comfort level PMV by the indoor environment detecting means.
[0097]
(20) Twentieth embodiment:
When the air conditioner is in the transient state 73 as shown in FIGS. 27 (a) and 27 (b), the rotation frequency of the compressor is the maximum frequency, and even if the set temperature is changed by about 3 ° C., the power consumption will not be reduced. Alternatively, if the set temperature is changed at this time, or if a stable state is reached, the comfort of the user is greatly impaired. In the case of the transient state 16, the state is as shown in the setting example 1 in Table 1. Although the frequency is within the range in which the frequency of the compressor can be controlled, the indoor environment is sufficiently stable due to the heat balance in the room. I can't say that. Therefore, when the operation of the air conditioner or the indoor air-conditioning environment is in a transient state, frequent changes in the set temperature do not lead to a reduction in power consumption, nor provide user comfort.
[0098]
In such transient states 73 and 74, the content of the demand operation mode is changed only once in accordance with the operation mode information of the air conditioner (desired by the user) from the wireless remote controller 64 and the demand request level. Even if the demand level is further changed during the transient state, the contents of the demand operation mode corresponding to the demand level are not transmitted to the air conditioner. The demand operation mode corresponding to the demand request level received by the demand control device during this time is transmitted from the transmission unit of the demand control device to the air conditioner when the state shifts to the stable state 75.
[0099]
(21) Twenty-first embodiment:
When the demand control device sets the indoor environment to the stable state 75, the demand operation mode is performed once within a range not exceeding the operating frequency of the compressor at the start of the demand control or within the power consumption according to a change in the indoor temperature or the PMV. Change above. FIG. 28 shows a temporal change of the room temperature 76 and the power consumption 77 when the set temperature change 78 is performed a plurality of times by the demand control device during the demand control when the indoor environment is stable in the cooling. By changing the set temperature within a range not exceeding the power consumption 77 'at the start of the demand control, it is possible to achieve both comfort and demand control.
[0100]
FIG. 29 is a flowchart simply illustrating the demand control method of the air conditioner according to (Embodiment 18) to (Embodiment 21).
The demand control device 60 measures the indoor / outdoor environment information and the operation start elapsed time of the air conditioner as shown in step 101, and is used for determining the indoor environment state in step 106.
After receiving the demand request (step 102), the demand operation mode of the air conditioner under demand control is determined based on the current indoor / outdoor environment, the current operation mode, and the demand request information from the power company (step 104). The determined demand operation mode is transmitted from the transmission unit 65 of the wireless remote controller of the demand control device 60 to the air conditioner (step 105).
When the indoor environment is in a stable state, the operation mode of the air conditioner may be changed based on the indoor and outdoor environment information after an elapse of an arbitrary time.
[0101]
(22) Twenty-second embodiment:
At the end of the demand control, FIGS. 30 (a) and 30 (b) respectively show the time change of the power consumption from the end of the demand control and the change of the operation mode (limited to the set temperature) by the demand control device. When the set temperature is returned to the operation mode at the time of starting the demand control as indicated by a dotted line 79 'in FIG. 7B, the power consumption increases at a stretch as indicated by a dotted line 80' in FIG. Since a considerable number of air conditioners in each home are connected to the power system including the power plant, there is a possibility that the power peak cut will be required again at the end of demand control. Therefore, as shown by the solid line 80 in FIG. 30A, the changed set temperature is changed 79 stepwise until the demand control starts according to the demand request, so that the integrated power consumption is almost the same as when the setting is changed at a stretch. However, it is possible to suppress the occurrence of instantaneous power peaks and prevent a situation such as a local power outage due to overloading of the power plant.
[0102]
FIG. 31 is a simplified flowchart showing the change of the set temperature of the air conditioner at the end of the demand control. At the end of the demand control (step 107), the set temperature is gradually changed over time to the set temperature before the start of the demand control (step 109).
[0103]
At the end of the demand control and at the start of the demand control, the indoor / outdoor environment is changed, and based on the indoor / outdoor environment information of the demand control device, the operation mode is changed to the operation mode determined by the calculation unit of the demand control device. You may. However, also in this case, it is necessary to gradually change the operation mode for the above-described reason.
