　（空気調和機１００の構成）

The air conditioner 100 which concerns on Embodiment 1 of this invention is demonstrated based on FIG.

FIG. 5 is a diagram illustrating a configuration and an operation cycle of the air conditioner 1 having only a cooling function in the air conditioner 100.
　図１に示すように、空気調和機１００は、可搬型の装置であり、外装体を成す筐体１０１を備えている。筐体１０１は、円筒形状を成す側面と、底面と、上面とを有している。上面は、上方に膨らむように曲面状に形成されている。 As shown in FIG. 1, the air conditioner 100 is a portable device and includes a housing 101 that forms an exterior body. The housing 101 has a cylindrical side surface, a bottom surface, and an upper surface. The upper surface is formed in a curved shape so as to swell upward.
　筐体１０１の側面には、上側に第１吸気口１０２が設けられ、下側に第２吸気口１０３が設けられている。第１吸気口１０２は、後述する凝縮器１２（図３参照）へ送風するための外気を取り込む開口である。第２吸気口１０３は、後述する蒸発器１４（図３参照）へ送風するための外気を取り込む開口である。 On the side surface of the housing 101, a first air inlet 102 is provided on the upper side, and a second air inlet 103 is provided on the lower side. The first air inlet 102 is an opening for taking in outside air for sending air to a condenser 12 (see FIG. 3) described later. The second air inlet 103 is an opening for taking in outside air for sending air to an evaporator 14 (see FIG. 3) described later.
　筐体１０１の側面における、第１吸気口１０２および第２吸気口１０３が設けられた部位と反対側には、排熱口１０４が設けられている。排熱口１０４は、後述する空気調和部１（図２参照）による空気調和動作の結果で生じた熱を排出する開口である。 A heat exhaust port 104 is provided on the side of the housing 101 opposite to the portion where the first air inlet 102 and the second air inlet 103 are provided. The heat exhaust port 104 is an opening through which heat generated as a result of the air conditioning operation by the air conditioning unit 1 (see FIG. 2) described later is discharged.
　筐体１０１の上面には、複数の吹き出し口１０５が設けられている。吹き出し口１０５は、上記の空気調和動作で生じた冷気または暖気を放出するための開口である。 A plurality of outlets 105 are provided on the upper surface of the housing 101. The outlet 105 is an opening for discharging cool air or warm air generated by the air conditioning operation.
　図２に示すように、空気調和機１００は、空気調和部１と、制御部２と、蓄電池３と、操作部４と、環境温度センサ５と、吹き出し温度センサ６とを備えている。 As shown in FIG. 2, the air conditioner 100 includes an air conditioner 1, a controller 2, a storage battery 3, an operation unit 4, an environmental temperature sensor 5, and a blowing temperature sensor 6.
　空気調和部１は、冷媒を介した外気との熱交換によって、環境温度（周囲温度）より低温の冷気または環境温度より高温の暖気を発生する空気調和動作を行う部分であり、蓄電池３に蓄えられた電力によって動作する。ここで、空気調和部１について、より詳細に説明する。 The air-conditioning unit 1 is a part that performs an air-conditioning operation that generates cold air lower than the environmental temperature (ambient temperature) or warm air higher than the environmental temperature by heat exchange with the outside air via the refrigerant. Operates with the power supplied. Here, the air conditioning unit 1 will be described in more detail.
　図３および図４に示すように、空気調和部１は、圧縮機１１と、凝縮器１２と、凝縮器ファン１３と、蒸発器１４と、蒸発器ファン１５と、膨張弁１６と、四方弁１７とを備えている。 As shown in FIGS. 3 and 4, the air conditioner 1 includes a compressor 11, a condenser 12, a condenser fan 13, an evaporator 14, an evaporator fan 15, an expansion valve 16, and a four-way valve. 17.
　図３に示すように、冷房運転時の空気調和部１において、圧縮機１１によって圧縮された高温かつ高圧の冷媒は、四方弁１７を介して凝縮器１２に送られる。冷媒は、凝縮器１２において、凝縮器ファン１３が第２吸気口１０３から吸い込んだ空気を凝縮器１２に向けて送ることによって冷却されると液化する。凝縮器１２を通過した空気は、凝縮器１２内の冷媒が液化することで放出した熱を含んだ状態で、排熱口１０４から排出される。 As shown in FIG. 3, the high-temperature and high-pressure refrigerant compressed by the compressor 11 in the air conditioning unit 1 during the cooling operation is sent to the condenser 12 via the four-way valve 17. In the condenser 12, the refrigerant liquefies when cooled by sending the air sucked from the second air inlet 103 by the condenser fan 13 toward the condenser 12. The air that has passed through the condenser 12 is discharged from the heat exhaust port 104 in a state that includes heat released by the refrigerant in the condenser 12 being liquefied.
　液化した冷媒は、膨張弁１６の微小なノズル穴から蒸発器１４内へ噴射されることで一気に気化する。気化した冷媒が蒸発器１４の周囲の熱を奪っていくことにより、蒸発器１４が冷やされる。そして、蒸発器ファン１５が第１吸気口１０２から取り入れた空気は、蒸発器１４を通過することで冷却される。蒸発器１４からの冷気は、吹き出し口１０５から放出される。蒸発器１４を出た冷媒は、圧縮機１１に戻って再び圧縮される。 The liquefied refrigerant is vaporized at a stroke by being injected into the evaporator 14 from a minute nozzle hole of the expansion valve 16. The evaporator 14 is cooled by the vaporized refrigerant taking heat around the evaporator 14. The air taken in from the first air inlet 102 by the evaporator fan 15 is cooled by passing through the evaporator 14. Cold air from the evaporator 14 is discharged from the outlet 105. The refrigerant exiting the evaporator 14 returns to the compressor 11 and is compressed again.
　図４に示すように、暖房運転時の空気調和部１において、圧縮機１１によって圧縮された高温かつ高圧の冷媒は、四方弁１７を介して凝縮器１２に送られる。冷媒は、凝縮器１２において、凝縮器ファン１３が第２吸気口１０３から吸い込んだ空気を凝縮器１２に向けて送ることによって冷却されると液化する。凝縮器１２を通過した空気は、凝縮器１２内の冷媒が液化することで放出した熱を含んだ状態で、吹き出し口１０５から暖気として放出される。 As shown in FIG. 4, the high-temperature and high-pressure refrigerant compressed by the compressor 11 in the air conditioning unit 1 during heating operation is sent to the condenser 12 via the four-way valve 17. In the condenser 12, the refrigerant liquefies when cooled by sending the air sucked from the second air inlet 103 by the condenser fan 13 toward the condenser 12. The air that has passed through the condenser 12 is released as warm air from the blowout port 105 in a state that includes heat released by the refrigerant in the condenser 12 being liquefied.
　液化した冷媒は、膨張弁１６に送られて、膨張弁１６の微小なノズル穴から蒸発器１４内へ噴射されることで一気に気化する。気化した冷媒が蒸発器１４の周囲の熱を奪っていくことにより、蒸発器１４が冷やされる。そして、蒸発器ファン１５が第１吸気口１０２から取り入れた空気は、蒸発器１４を通過することで冷却される。蒸発器１４からの冷気は、排熱口１０４から排出される。蒸発器１４を出た冷媒は、圧縮機１１に戻って再び圧縮される。 The liquefied refrigerant is sent to the expansion valve 16 and is vaporized at a stroke by being injected into the evaporator 14 from a minute nozzle hole of the expansion valve 16. The evaporator 14 is cooled by the vaporized refrigerant taking heat around the evaporator 14. The air taken in from the first air inlet 102 by the evaporator fan 15 is cooled by passing through the evaporator 14. The cold air from the evaporator 14 is discharged from the heat exhaust port 104. The refrigerant exiting the evaporator 14 returns to the compressor 11 and is compressed again.
　なお、空気調和部１は、２つの熱交換器（第１熱交換器および第２熱交換器）を有している。冷房時には、第１熱交換器が凝縮器１２として機能し、第２熱交換器が蒸発器１４として機能する。一方、暖房時には、第１熱交換器が蒸発器１４として機能し、第２熱交換器が凝縮器１２として機能する。このため、図３および図４では、凝縮器１２および蒸発器１４の位置が入れ替わっている。この入れ替えに伴って、凝縮器ファン１３および蒸発器ファン１５の位置も入れ替わっている。 The air conditioner 1 has two heat exchangers (a first heat exchanger and a second heat exchanger). During cooling, the first heat exchanger functions as the condenser 12 and the second heat exchanger functions as the evaporator 14. On the other hand, during heating, the first heat exchanger functions as the evaporator 14 and the second heat exchanger functions as the condenser 12. For this reason, the positions of the condenser 12 and the evaporator 14 are interchanged in FIGS. 3 and 4. With this replacement, the positions of the condenser fan 13 and the evaporator fan 15 are also switched.
　ところで、四方弁１７を設けると空気調和機１００が大型になる。そこで、空気調和機１００は、図５に示すように、空気調和部１が四方弁１７を備えないことにより、冷房機能のみを備えていてもよい。 By the way, if the four-way valve 17 is provided, the air conditioner 100 becomes large. Therefore, as shown in FIG. 5, the air conditioner 100 may have only a cooling function because the air conditioner 1 does not include the four-way valve 17.
　ここで、図２を参照した空気調和機１００の説明に戻る。 Here, it returns to description of the air conditioner 100 with reference to FIG.
　蓄電池３は、充放電可能な二次電池である。蓄電池３は、空気調和部１および制御部２に電力を供給する。また、蓄電池３は、残電力の情報を出力する。 The storage battery 3 is a chargeable / dischargeable secondary battery. The storage battery 3 supplies power to the air conditioning unit 1 and the control unit 2. Moreover, the storage battery 3 outputs information on remaining power.
　操作部４は、空気調和部１の運転を操作したり、空調温度などを設定したりするための入力操作を受け付ける部分である。操作部４は、運転モードを選択するモード選択スイッチと、吹き出し温度を設定する温度設定スイッチと、連続運転時間を設定する時間設定スイッチとを有している。モード選択スイッチは、通常運転モードまたは運転時間優先モードを選択するスイッチである。通常運転モードは、温度設定スイッチによって設定された目標の吹き出し温度（目標吹き出し温度）となるように、蓄電池３の残電力に関係なく運転条件決定部によって決定された運転条件で空気調和部１を運転するモードである。運転時間優先モードは、時間設定スイッチによって設定された連続運転時間での運転が可能となるように、運転条件決定部２３によって決定された運転条件で空気調和部１を運転するモードである。 The operation unit 4 is a part that receives an input operation for operating the air conditioning unit 1 or setting an air conditioning temperature. The operation unit 4 includes a mode selection switch for selecting an operation mode, a temperature setting switch for setting a blowing temperature, and a time setting switch for setting a continuous operation time. The mode selection switch is a switch for selecting a normal operation mode or an operation time priority mode. In the normal operation mode, the air conditioner 1 is operated under the operation condition determined by the operation condition determination unit regardless of the remaining power of the storage battery 3 so that the target blow temperature (target blow temperature) set by the temperature setting switch is obtained. It is a mode to drive. The operation time priority mode is a mode in which the air conditioning unit 1 is operated under the operation condition determined by the operation condition determination unit 23 so that the operation can be performed with the continuous operation time set by the time setting switch.
　環境温度センサ５は、空気調和機１００の周囲温度である環境温度を計測するセンサである。環境温度センサ５は、その検出部が筐体１０１の外表面に露出するように筐体１０１に取り付けられている。 The environmental temperature sensor 5 is a sensor that measures the environmental temperature that is the ambient temperature of the air conditioner 100. The environmental temperature sensor 5 is attached to the housing 101 such that the detection unit is exposed on the outer surface of the housing 101.
　吹き出し温度センサ６は、吹き出し口１０５から吹き出される空気の温度（吹き出し温度）を計測するセンサである。吹き出し温度センサ６は、筐体１０１の内面における吹き出し口１０５の周辺に取り付けられている。 The blowing temperature sensor 6 is a sensor that measures the temperature of the air blown from the blowing port 105 (blowing temperature). The blowing temperature sensor 6 is attached to the periphery of the blowing port 105 on the inner surface of the housing 101.
　制御部２は、空気調和部１の動作を制御する部分であり、例えば、マイクロコンピュータによって構成されている。制御部２は、メモリ２１（記憶部）と、温度差算出部２２と、運転条件決定部２３と、運転制御部２４とを有している。 The control unit 2 is a part that controls the operation of the air conditioning unit 1, and is configured by, for example, a microcomputer. The control unit 2 includes a memory 21 (storage unit), a temperature difference calculation unit 22, an operation condition determination unit 23, and an operation control unit 24.
　メモリ２１は、運転テーブルと、操作部４で設定された目標吹き出し温度および連続運転時間とを記憶している。運転テーブルは、表１に示すように、温度差［℃］と、消費電力［Ｗ／ｈ］と、圧縮機１１の回転数［ｒｐｍ］と、凝縮器ファン１３の回転数［ｒｐｍ］と、蒸発器ファン１５の回転数［ｒｐｍ］とを対応付けたテーブルを複数含んでいる。各テーブルには、テーブル番号ＴＮが付与されている。圧縮機１１の回転数、凝縮器ファン１３の回転数および蒸発器ファン１５の回転数は、空気調和部１の運転条件となる。このような運転条件は、基礎実験で得られた最適な値に決められている。 The memory 21 stores an operation table, a target blowing temperature set by the operation unit 4, and a continuous operation time. As shown in Table 1, the operation table includes a temperature difference [° C.], power consumption [W / h], a rotation speed [rpm] of the compressor 11, a rotation speed [rpm] of the condenser fan 13, and A plurality of tables in which the rotation speed [rpm] of the evaporator fan 15 is associated are included. Each table is assigned a table number TN. The rotational speed of the compressor 11, the rotational speed of the condenser fan 13, and the rotational speed of the evaporator fan 15 are the operating conditions of the air conditioner 1. Such operating conditions are determined to be optimum values obtained in the basic experiment.
Figure JPOXMLDOC01-appb-T000001
 　温度差は、環境温度センサ５によって検出された環境温度と、メモリ２１に記憶された目標吹き出し温度との差である。各テーブルの温度差は、例えば、２℃の範囲を有している。ＴＮ＝１のテーブルの温度差の範囲は、０℃以上かつ２℃未満である。ＴＮ＝２のテーブルの温度差の範囲は、２℃以上かつ４℃未満である。ＴＮ＝３のテーブルの温度差の範囲は、４℃以上かつ６℃未満である。ＴＮ＝４のテーブルの温度差の範囲は、６℃以上かつ８℃未満である。ＴＮ＝５のテーブルの温度差の範囲は、８℃以上かつ１０℃未満である。ＴＮ＝６のテーブルの温度差の範囲は、１０℃以上かつ１２℃未満である。
Figure JPOXMLDOC01-appb-T000001
 The temperature difference is a difference between the environmental temperature detected by the environmental temperature sensor 5 and the target blowing temperature stored in the memory 21. The temperature difference between the tables has a range of 2 ° C., for example. The range of the temperature difference of the table with TN = 1 is 0 ° C. or more and less than 2 ° C. The range of the temperature difference of the table with TN = 2 is 2 ° C. or more and less than 4 ° C. The range of the temperature difference of the table with TN = 3 is 4 ° C. or more and less than 6 ° C. The range of the temperature difference of the table of TN = 4 is 6 degreeC or more and less than 8 degreeC. The range of the temperature difference of the table of TN = 5 is 8 degreeC or more and less than 10 degreeC. The range of the temperature difference of the table with TN = 6 is 10 ° C. or more and less than 12 ° C.
　消費電力（基礎消費電力）は、テーブルにおいて対応する、圧縮機１１の回転数、凝縮器ファン１３の回転数および蒸発器ファン１５の回転数で空気調和部１を運転したときの予測の単位時間当たり（ここでは１時間あたり）の消費電力である。運転テーブルにおいて、各テーブルの消費電力Ｗ１～Ｗ６、圧縮機１１の回転数（圧縮機回転数Ｃ１～Ｃ６）、凝縮器ファン１３の回転数（凝縮器ファン回転数ＦＣ１～ＦＣ６）および蒸発器ファン１５の回転数（蒸発器ファン回転数ＦＥ１～ＦＥ６）は、それぞれテーブル番号ＴＮが大きいほど大きい値となる。 Power consumption (basic power consumption) is a predicted unit time when the air conditioner 1 is operated at the rotation speed of the compressor 11, the rotation speed of the condenser fan 13 and the rotation speed of the evaporator fan 15 corresponding to each other in the table. It is the power consumption per hit (per hour here). In the operation table, the power consumption W1 to W6 of each table, the rotational speed of the compressor 11 (compressor rotational speed C1 to C6), the rotational speed of the condenser fan 13 (condenser fan rotational speed FC1 to FC6), and the evaporator fan The number of revolutions 15 (evaporator fan revolutions FE1 to FE6) increases as the table number TN increases.
　温度差算出部２２は、運転時間優先モードが選択されているときに、上記の環境温度センサ５によって検出された環境温度と、メモリ２１に記憶された目標吹き出し温度との差（温度差）を算出する。 The temperature difference calculation unit 22 calculates a difference (temperature difference) between the environmental temperature detected by the environmental temperature sensor 5 and the target blowing temperature stored in the memory 21 when the operation time priority mode is selected. calculate.
　運転条件決定部２３は、運転時間優先モードが選択されたとき、メモリ２１に記憶された運転テーブルを参照して、温度差算出部２２によって算出された温度差と、蓄電池３から取得した残電力の情報とに基づいて運転条件を決定する。具体的には、運転条件決定部２３は、温度差が入る温度範囲に対応する消費電力と、時間設定スイッチによって設定された連続運転時間との積で定まる消費電力（運転消費電力）が蓄電池３の残電力未満となるように選択されたテーブルから運転条件を決定する。 When the operation time priority mode is selected, the operation condition determination unit 23 refers to the operation table stored in the memory 21 and the temperature difference calculated by the temperature difference calculation unit 22 and the remaining power acquired from the storage battery 3. The operating conditions are determined based on the information. Specifically, the operating condition determination unit 23 determines that the power consumption (operating power consumption) determined by the product of the power consumption corresponding to the temperature range in which the temperature difference enters and the continuous operation time set by the time setting switch is the storage battery 3. The operating conditions are determined from the table selected to be less than the remaining power.
　運転制御部２４は、運転条件決定部２３によって決定された運転条件に基づいて空気調和部１の運転を制御する。具体的には、運転制御部２４は、圧縮機１１、凝縮器ファン１３および蒸発器ファン１５のそれぞれの回転数が、運転条件決定部２３によって選択されたテーブルの圧縮機回転数、凝縮器ファン回転数および蒸発器ファン回転数となるように、空気調和部１の運転を制御する。 The operation control unit 24 controls the operation of the air conditioning unit 1 based on the operation condition determined by the operation condition determination unit 23. Specifically, the operation control unit 24 determines that the rotation speeds of the compressor 11, the condenser fan 13, and the evaporator fan 15 are the compressor rotation speed of the table selected by the operation condition determination unit 23, and the condenser fan. The operation of the air conditioner 1 is controlled so as to be the rotational speed and the evaporator fan rotational speed.
　（空気調和機１００の動作）
　空気調和機１００の運転時間優先モード時の動作を図６のフローチャートを参照して説明する。図６は、空気調和機１００の動作手順を示すフローチャートである。 (Operation of the air conditioner 100)
The operation of the air conditioner 100 in the operation time priority mode will be described with reference to the flowchart of FIG. FIG. 6 is a flowchart showing an operation procedure of the air conditioner 100.
　図６に示すように、まず、運転条件決定部２３は、ユーザによって運転時間設定モードが選択されたか否かを判定する（ステップＳ１）。ステップＳ１において、運転条件決定部２３は、運転時間優先モードが選択されなかったと判定すると（ＮＯ）、運転時間優先モードを実行せずに処理を終える。なお、通常運転モードが選択されているとき、運転条件決定部２３は、温度設定スイッチによって設定された目標吹き出し温度となるように運転条件を決定する。 As shown in FIG. 6, first, the operating condition determination unit 23 determines whether or not the operating time setting mode has been selected by the user (step S1). In step S1, if the operation condition determination unit 23 determines that the operation time priority mode is not selected (NO), the operation condition determination unit 23 ends the process without executing the operation time priority mode. When the normal operation mode is selected, the operation condition determination unit 23 determines the operation condition so that the target blowing temperature set by the temperature setting switch is obtained.
　ステップＳ１において、運転時間優先モードが選択されたことを運転条件決定部２３が判定すると（ＹＥＳ）、温度差算出部２２は、環境温度センサ５から環境温度を取り込む（ステップＳ２）。次いで、温度差算出部２２は、メモリ２１に記憶された目標吹き出し温度を読み込み、運転条件決定部２３は、連続運転時間Ｈを読み込む（ステップＳ３）。ここで、温度差算出部２２は、環境温度と目標吹き出し温度との温度差を算出する。 In step S1, when the operation condition determination unit 23 determines that the operation time priority mode has been selected (YES), the temperature difference calculation unit 22 takes in the environmental temperature from the environmental temperature sensor 5 (step S2). Next, the temperature difference calculation unit 22 reads the target blowing temperature stored in the memory 21, and the operation condition determination unit 23 reads the continuous operation time H (step S3). Here, the temperature difference calculation unit 22 calculates a temperature difference between the environmental temperature and the target blowing temperature.
　続いて、運転条件決定部２３は、温度差算出部２２によって算出された温度差からテーブル番号ＴＮを求める（ステップＳ４）。運転条件決定部２３は、運転テーブルを参照して、温度差が入る温度範囲を含むテーブルを選択することで、当該テーブルのテーブル番号ＴＮを求める。例えば、温度差が５℃である場合、運転条件決定部２３は、テーブル番号“３”を求める。 Subsequently, the operating condition determination unit 23 obtains a table number TN from the temperature difference calculated by the temperature difference calculation unit 22 (step S4). The operation condition determination unit 23 refers to the operation table and selects a table including a temperature range in which a temperature difference enters, thereby obtaining the table number TN of the table. For example, when the temperature difference is 5 ° C., the operating condition determination unit 23 obtains the table number “3”.
　さらに、運転条件決定部２３は、求めたテーブル番号ＴＮのテーブルから消費電力Ｗ［ＴＮ］を求め（ステップＳ５）、蓄電池３から残電力（ＢＣ）の情報を取り込む（ステップＳ６）。 Furthermore, the operating condition determination unit 23 obtains the power consumption W [TN] from the table of the obtained table number TN (Step S5), and takes in the information on the remaining power (BC) from the storage battery 3 (Step S6).
　そして、運転条件決定部２３は、残電力（ＢＣ）が、消費電力Ｗ［ＴＮ］と連続運転時間Ｈとの積（運転消費電力）以上であるか否かを判定する（ステップＳ７）。ステップＳ７において、運転条件決定部２３は、残電力が運転消費電力以上であると判定すると（ＹＥＳ）、選択したテーブル番号ＴＮのテーブルに含まれる運転条件を決定する。運転制御部２４は、決定された運転条件で空気調和部１の運転を制御する（ステップＳ８）。 Then, the operating condition determination unit 23 determines whether or not the remaining power (BC) is equal to or greater than the product (operating power consumption) of the power consumption W [TN] and the continuous operation time H (step S7). In step S7, if the operating condition determining unit 23 determines that the remaining power is equal to or higher than the operating power consumption (YES), the operating condition is determined to be included in the table of the selected table number TN. The operation control unit 24 controls the operation of the air conditioning unit 1 under the determined operation condition (step S8).
　また、ステップＳ７において、運転条件決定部２３は、残電力が運転消費電力以上でない（運転消費電力未満である）と判定すると（ＮＯ）、テーブル番号ＴＮから１を減じて（ステップＳ９）、処理をステップＳ５に戻す。 In step S7, if the operating condition determining unit 23 determines that the remaining power is not equal to or higher than the operating power consumption (less than the operating power consumption) (NO), 1 is subtracted from the table number TN (step S9), and the process is performed. Is returned to step S5.
　以上のように、本実施形態に係る空気調和機１００は、メモリ２１と、運転条件決定部２３と、運転制御部２４とを備えている。メモリ２１は、環境温度と目標吹き出し温度との温度差の所定の温度範囲を空気調和部１の運転条件および基礎消費電力と対応付けたテーブルを、複数の異なる温度範囲について記憶する。運転条件決定部２３は、温度差が入る温度範囲に対応する基礎消費電力と指定された連続運転時間とで定まる運転消費電力が、蓄電池３の残電力未満となるように選択されたテーブルから運転条件を決定する。運転制御部２４は、決定された運転条件で空気調和部１の運転を制御する。 As described above, the air conditioner 100 according to the present embodiment includes the memory 21, the operation condition determination unit 23, and the operation control unit 24. The memory 21 stores, for a plurality of different temperature ranges, a table in which a predetermined temperature range of the temperature difference between the environmental temperature and the target blowing temperature is associated with the operating condition and basic power consumption of the air conditioning unit 1. The operation condition determination unit 23 operates from a table selected so that the operation power consumption determined by the basic power consumption corresponding to the temperature range where the temperature difference enters and the specified continuous operation time is less than the remaining power of the storage battery 3. Determine the conditions. The operation control unit 24 controls the operation of the air conditioning unit 1 under the determined operation conditions.
　これにより、温度差が入る温度範囲に対応した消費電力が蓄電池３の残電力を超えるときには、連続運転時間内で消費電力が残電力未満となるように選択された運転条件で空気調和部１が運転される。これにより、連続運転時間内に残電力を超えない範囲で常に温度差を最大に維持しながら空気調和部１を運転することができる。したがって、連続運転時間内では、ユーザの希望する吹き出し温度に近づけることができる。 Thereby, when the power consumption corresponding to the temperature range where the temperature difference enters exceeds the remaining power of the storage battery 3, the air conditioner 1 operates under the operating conditions selected so that the power consumption is less than the remaining power within the continuous operation time. Driven. As a result, the air conditioner 1 can be operated while the temperature difference is always maintained at the maximum within a range not exceeding the remaining power within the continuous operation time. Therefore, it is possible to approach the blowing temperature desired by the user within the continuous operation time.
　また、運転条件決定部２３は、運転消費電力が蓄電池３の残電力以下であるときに、消費電力に対応する運転条件を決定する一方、運転消費電力が残電力を超えるとき、選択されたテーブルの温度範囲より１つ小さい温度範囲を含むテーブルから新たな運転条件を決定する。 In addition, the operating condition determining unit 23 determines the operating condition corresponding to the power consumption when the operating power consumption is equal to or less than the remaining power of the storage battery 3, while the selected table is selected when the operating power consumption exceeds the remaining power. A new operating condition is determined from a table including a temperature range one smaller than the temperature range.
　これにより、運転消費電力が蓄電池３の残電力を超えるときには、運転消費電力が小さくなるように運転条件を決定することができる。 Thereby, when the driving power consumption exceeds the remaining power of the storage battery 3, the driving conditions can be determined so that the driving power consumption becomes small.
　〔実施形態２〕
　本発明の実施形態２について図２および図７を用いて説明すれば、以下のとおりである。なお、本実施形態において、実施形態１における構成要素と同等の機能を有する構成要素については、同一の符号を付記して、その説明を省略する。 [Embodiment 2]
Embodiment 2 of the present invention will be described below with reference to FIGS. 2 and 7. In the present embodiment, components having functions equivalent to those of the components in the first embodiment are denoted by the same reference numerals and description thereof is omitted.
　本実施形態に係る空気調和機１００は、定期的に温度差を算出して運転条件を更新する点で実施形態１の空気調和機１００と異なっている。以下に、本実施形態に係る空気調和機１００の運転時間優先モード時の動作を図７のフローチャートを参照して説明する。図７は、本実施形態に係る空気調和機１００の動作手順を示すフローチャートである。 The air conditioner 100 according to the present embodiment is different from the air conditioner 100 according to the first embodiment in that the temperature difference is periodically calculated and the operation conditions are updated. Below, the operation | movement at the time of operation time priority mode of the air conditioner 100 which concerns on this embodiment is demonstrated with reference to the flowchart of FIG. FIG. 7 is a flowchart showing an operation procedure of the air conditioner 100 according to the present embodiment.
　図７に示すように、まず、運転条件決定部２３は、ユーザによって運転時間設定モードが選択されたか否かを上述のステップＳ１と同じように判定する（ステップＳ１１）。ステップＳ１１において、運転条件決定部２３は、運転時間優先モードが選択されなかったと判定すると（ＮＯ）、運転時間優先モードを実行せずに処理を終える。 As shown in FIG. 7, first, the operation condition determination unit 23 determines whether or not the operation time setting mode has been selected by the user in the same manner as in step S1 described above (step S11). In step S11, if the operation condition determination unit 23 determines that the operation time priority mode is not selected (NO), the operation condition determination unit 23 ends the process without executing the operation time priority mode.
　ステップＳ１１において、運転時間優先モードが選択されたことを運転条件決定部２３が判定すると（ＹＥＳ）、温度差算出部２２は、環境温度センサ５から環境温度を取り込む（ステップＳ１２）。次いで、温度差算出部２２は、メモリ２１に記憶された目標吹き出し温度を読み込み、運転条件決定部２３は、連続運転時間ＴＴを読み込む（ステップＳ１３）。ここで、温度差算出部２２は、環境温度と目標吹き出し温度との温度差を算出する。 In step S11, when the operation condition determination unit 23 determines that the operation time priority mode is selected (YES), the temperature difference calculation unit 22 takes in the environmental temperature from the environmental temperature sensor 5 (step S12). Next, the temperature difference calculation unit 22 reads the target blowing temperature stored in the memory 21, and the operation condition determination unit 23 reads the continuous operation time TT (step S13). Here, the temperature difference calculation unit 22 calculates a temperature difference between the environmental temperature and the target blowing temperature.
　続いて、運転条件決定部２３は、温度差算出部２２によって算出された温度差からテーブル番号ＴＮを求める（ステップＳ１４）。運転条件決定部２３は、上述のステップＳ５と同じようにして、求めたテーブル番号ＴＮのテーブルから消費電力Ｗ［ＴＮ］を求め（ステップＳ１５）、蓄電池３から残電力（ＢＣ）の情報を取り込む（ステップＳ１６）。 Subsequently, the operating condition determination unit 23 obtains a table number TN from the temperature difference calculated by the temperature difference calculation unit 22 (step S14). The operating condition determination unit 23 obtains the power consumption W [TN] from the table of the obtained table number TN in the same manner as in step S5 described above (step S15), and takes in the information on the remaining power (BC) from the storage battery 3. (Step S16).
　そして、運転条件決定部２３は、残電力（ＢＣ）が、消費電力Ｗ［ＴＮ］と連続運転時間ＴＴとの積である運転消費電力以上であるか否かを判定する（ステップＳ１７）。ステップＳ１７において、運転条件決定部２３が、残電力が運転消費電力以上であると判定すると（ＹＥＳ）、選択したテーブル番号ＴＮのテーブルに含まれる運転条件を決定する。運転制御部２４は、決定された運転条件で空気調和部１の運転を制御する（ステップＳ１８）。 Then, the operation condition determination unit 23 determines whether or not the remaining power (BC) is equal to or greater than the operation power consumption that is the product of the power consumption W [TN] and the continuous operation time TT (step S17). If the operating condition determining unit 23 determines in step S17 that the remaining power is equal to or greater than the operating power consumption (YES), the operating condition included in the table of the selected table number TN is determined. The operation control unit 24 controls the operation of the air conditioning unit 1 under the determined operation condition (step S18).
　また、ステップＳ１７において、運転条件決定部２３は、残電力が運転消費電力以上でない（運転消費電力未満である）と判定すると（ＮＯ）、テーブル番号ＴＮから１を減じて（ステップＳ１９）、処理をステップＳ１５に戻す。 In step S17, when the operating condition determining unit 23 determines that the remaining power is not equal to or higher than the operating power consumption (less than the operating power consumption) (NO), 1 is subtracted from the table number TN (step S19), and the process is performed. Is returned to step S15.
　ステップＳ１８の後、運転条件決定部２３は、後述する待機時間ＴＷを待機する待機回数ｎを１に設定し（ステップＳ２０）、一定の待機時間ＴＷ待機する（ステップＳ２１）。その後、運転条件決定部２３は、温度差算出部２２によって新たに算出された、環境温度と吹き出し温度センサ６によって計測された吹き出し温度との温度差からテーブル番号ＴＮを求め（ステップＳ２２）、求めたテーブル番号ＴＮのテーブルから消費電力Ｗ［ＴＮ］を求める（ステップＳ２３）。 After step S18, the operating condition determination unit 23 sets the number of standby times n to wait for a waiting time TW described later to 1 (step S20), and waits for a certain waiting time TW (step S21). Thereafter, the operating condition determination unit 23 obtains the table number TN from the temperature difference between the environmental temperature newly calculated by the temperature difference calculation unit 22 and the blowing temperature measured by the blowing temperature sensor 6 (step S22). The power consumption W [TN] is obtained from the table with the table number TN (step S23).
　そして、運転条件決定部２３は、蓄電池３から残電力（ＢＣ）の情報を取り込む（ステップＳ２４）。運転条件決定部２３は、残電力（ＢＣ）が、消費電力Ｗ［ＴＮ］と、連続運転時間ＴＴから待機時間ＴＷと待機回数ｎとの積を減じた時間（残り運転時間）との積である運転消費電力以上であるか否かを判定する（ステップＳ２５）。 And the operating condition determination part 23 takes in the information of remaining power (BC) from the storage battery 3 (step S24). The operating condition determination unit 23 calculates the remaining power (BC) as the product of the power consumption W [TN] and the time obtained by subtracting the product of the standby time TW and the number of standby times n from the continuous operation time TT (remaining operation time). It is determined whether it is more than a certain driving power consumption (step S25).
　ステップＳ２５において、運転条件決定部２３は、残電力が運転消費電力以上であると判定すると（ＹＥＳ）、さらに、待機時間ＴＷが残り運転時間以下であるか否かを判定する（ステップＳ２６）。ステップＳ２６において、運転条件決定部２３は、待機時間ＴＷが残り運転時間以下でない（残り運転時間を超える）と判定すると（ＮＯ）、さらに待機時間ＴＷが確保できないと判断して、選択したテーブル番号ＴＮのテーブルに含まれる運転条件を決定する。運転制御部２４は、決定された運転条件で空気調和部１の運転を制御する（ステップＳ２７）。 In step S25, when the operating condition determining unit 23 determines that the remaining power is equal to or greater than the operating power consumption (YES), it further determines whether or not the standby time TW is less than or equal to the remaining operating time (step S26). In step S26, if the operation condition determination unit 23 determines that the standby time TW is not less than the remaining operation time (exceeds the remaining operation time) (NO), the operation condition determination unit 23 determines that the standby time TW cannot be secured and selects the selected table number. The operating conditions included in the TN table are determined. The operation control unit 24 controls the operation of the air conditioning unit 1 under the determined operation condition (step S27).
　また、ステップＳ２５において、運転条件決定部２３は、残電力が運転消費電力を超えると判定すると（ＮＯ）、残電力での運転ができないと判断して、テーブル番号ＴＮから１を減じて（ステップＳ２８）、処理をステップＳ２３に戻す。 In step S25, if the operating condition determining unit 23 determines that the remaining power exceeds the operating power consumption (NO), the operating condition determining unit 23 determines that the operation with the remaining power cannot be performed and subtracts 1 from the table number TN (step S25). S28) The process returns to step S23.
　また、ステップＳ２６において、運転条件決定部２３は、待機時間ＴＷが残り運転時間以下であると判定すると（ＹＥＳ）、選択したテーブル番号ＴＮのテーブルに含まれる運転条件を決定する。運転制御部２４は、決定された運転条件で空気調和部１の運転を制御する（ステップＳ２９）。 In step S26, when the operating condition determining unit 23 determines that the standby time TW is less than or equal to the remaining operating time (YES), the operating condition is determined to be included in the table of the selected table number TN. The operation control unit 24 controls the operation of the air conditioning unit 1 under the determined operation condition (step S29).
　運転条件決定部２３は、待機時間ＴＷが残り運転時間以上であるときには待機時間ＴＷが確保できると判断し、待機回数ｎに１を加えて（ステップＳ３０）、処理をステップＳ２１に戻す。 The operating condition determination unit 23 determines that the standby time TW can be secured when the standby time TW is equal to or longer than the remaining operating time, adds 1 to the standby count n (step S30), and returns the process to step S21.
　以上のように、本実施形態に係る空気調和機１００は、運転条件決定部２３が、一定時間（待機時間ＴＷ）ごとに取得した温度差に基づいて前記運転条件を決定する。 As described above, in the air conditioner 100 according to the present embodiment, the operation condition determination unit 23 determines the operation condition based on the temperature difference acquired every predetermined time (standby time TW).
　これにより、逐次変化する蓄電池３の残電力に応じて運転条件が更新される。それゆえ、残り運転時間で吹き出し温度を目標吹き出し温度にできるだけ近づけるように空気調和部１を運転することができる。 Thereby, the operating condition is updated according to the remaining power of the storage battery 3 that changes sequentially. Therefore, the air conditioner 1 can be operated so that the blowing temperature is as close as possible to the target blowing temperature during the remaining operation time.
　運転条件決定部２３は、決定した運転条件による空気調和部１の運転が行われている状態を一定時間待機してから取得した温度差に基づいて運転条件を決定する。また、運転条件決定部２３は、連続運転時間ＴＴから一定時間と待機の回数との積である総待機時間（ＴＷ×ｎ）を減じた残り運転時間内に一定時間を確保できると判定したときに、一定時間待機する。 The operating condition determination unit 23 determines the operating condition based on the temperature difference acquired after waiting for a certain period of time during which the air conditioning unit 1 is operating under the determined operating condition. In addition, when the operation condition determination unit 23 determines that the fixed time can be secured within the remaining operation time obtained by subtracting the total standby time (TW × n), which is the product of the fixed time and the number of standby times, from the continuous operation time TT. Wait for a certain time.
　これにより、連続運転時間内で可能な限り運転条件を更新することができる。 This makes it possible to update the operating conditions as much as possible within the continuous operation time.
