  Hereinafter, with reference to the drawings, the air supply / exhaust operation indoors and outdoors performed at the time of "rest cooling operation" on a hot and uncomfortable night by an air conditioner according to an embodiment of the present invention (hereinafter referred to as the present embodiment) Will be described in detail. In addition, “cooling operation” of “resting cooling operation” in this specification means not only a known cooling operation but also a method in which a dehumidifying operation having a similar effect is combined or switched to a cooling operation, or only a dehumidifying operation. Or in some cases only by the air blowing operation. In the air conditioner of the present invention, when the operation in the rest / air supply operation (combination operation of the rest cooling operation and supply / exhaust operation) mode is instructed, the above-mentioned “cooling operation” is the supply / exhaust operation. It is executed independently.

  Here, the details of the structure and operation of the air supply / exhaust device provided in the indoor unit of the air conditioner are described in detail in the above-mentioned Japanese Patent Application No. 2003-148698. Is omitted. Moreover, since the apparatus structure of an air conditioner and the operation | movement of the refrigerating cycle for various air conditioning operations are also known, description is abbreviate | omitted.

  FIG. 1 is a block diagram illustrating a configuration of a control system in the air conditioner of the present embodiment. In FIG. 1, 100 is an air conditioner control device, 200 is an operation means, 300 is an indoor temperature sensor, 400 is an indoor humidity sensor, 500 is an outdoor temperature sensor, 600 is an air conditioner actuator, and 700 is an air supply / exhaust device. Actuator. The air conditioner control device 100 includes a rest operation control means 101, an air conditioner control means 102, an air supply / exhaust control means 103, an air supply / exhaust apparatus control means 104, and the like.

  The control device 100 of the air conditioner receives an operation command by an operation signal of a “rest air” button of the operation unit 200, and an indoor temperature sensor 300, an indoor humidity sensor 400, an outdoor temperature sensor by a sensor data acquisition unit (not shown). The measurement value of 500 is acquired, and the air conditioner actuator 600 is driven and controlled to operate the air conditioner in a specified operation mode (rest / air supply operation mode) based on the obtained measurement value.

  Here, the actuator 600 of the air conditioner includes a compressor, an indoor / outdoor blower, an electric expansion valve for pressure reduction control, a four-way valve for switching a refrigerant flow path, various valves for switching a refrigerant circuit, and the like.

  In particular, in the portion according to the present invention, when the “rest air” button of the operation means 200 is pressed, the rest operation control means 101 of the control device 100 of the air conditioner senses this, and Patent Document 1 And the rest operation currently disclosed by patent document 2 etc. is started, Based on the information of the said sensor data acquisition means, a required air conditioner operating condition is instruct | indicated to the air conditioner control means 102. FIG. Further, when the end condition of the rest operation is reached, the air conditioner control means 102 is commanded to stop the air conditioner. The air conditioner control means 102 outputs a drive signal in accordance with the command to the actuator of the air conditioner.

  At the same time, the rest operation control means 101 transmits a signal indicating that the rest operation is being performed to the air supply / exhaust control means 103 during the rest operation. The air supply / exhaust control means 103 sends a necessary air supply operation signal or supply air stop signal to the air supply / exhaust apparatus control means 104 while the signal during the rest operation is transmitted. The exhaust device actuator 700 is driven.

  The actuator 700 of the air supply / exhaust device includes a blower fan, a damper for switching the air flow path, and the like.

  In addition, the air conditioner control means 102 sends an operation request for the air conditioner indoor fan required for determining the air supply operation condition to the air conditioner control means 102, and the air conditioner control means 102 sends a drive signal along the air conditioner control means 102. Output to actuator (indoor fan) 600.

  FIG. 2 shows a configuration example of the operation means 200 of the present embodiment. Reference numeral 201 denotes a display unit that uses liquid crystal or the like, and displays various operation statuses and operation statuses of the air conditioner. In the figure, those indicated by ○ are various operation buttons. The button 210 is displayed as “Closed”, and the button 220 is displayed as “Closed Air”. The “rest” button 210 for the conventional rest operation is left as it is, and the “rest air” button 220 makes the rest / supply operation according to the present invention in combination with air supply and exhaust during the rest operation independent. Can be specified. The rest / air supply operation is started by pressing the “night air supply” button 220. In addition, when the conventional rest operation is not required, only the button 210 or the button 220 may be used, and the rest / air supply operation of the present invention may be started by pressing it.

  FIG. 3 shows a time chart of the air supply control during “rest air cooling operation” in the rest / air supply operation according to the present embodiment, and the horizontal axis represents the progress of time. In the figure, 1000 indicates that the vehicle is in a rest / air supply operation. During rest / air supply operation, air supply conditions are determined based on the outdoor temperature, room temperature, and room humidity at the positions indicated by 2300, 2400,. , Control resume.

  When the rest / air supply operation is started, the forced air supply operation for at least T1 time indicated by 2000 in the figure is started. The forced air supply operation time T1 at the start of the rest / air supply operation is determined as, for example, T1 = 30 minutes, and the air supply operation is surely performed for indoor residents who set the rest / air supply operation by button operation. This is provided as a special air supply operation in order to notify the user that the operation has been performed (for example, to notify by turning on a display lamp during supply) and to be relieved. It is not necessary to limit the time T1 to 30 minutes. Of course, the time T1 may be set to an appropriate time between about 10 minutes and 30 minutes if the above purpose is achieved. This may seem like a waste, but it is important for a proper man-machine interface.

  When Tm = T1-Ts time elapses, the air supply condition is determined for Ts time indicated by 2300 in the figure. That is, the value Ti of the indoor temperature sensor 300, the value Hi of the indoor humidity sensor 400, and the value To of the outdoor temperature sensor 500 are monitored, and To ≧ (Ti + α1) or Hi ≧ β or Ti <(Tr−α2) is being monitored. If it continues, the air supply operation is stopped. Here, Tr is the indoor temperature target set value at the time of rest operation.

  Here, the condition To ≧ (Ti + α1) is determined as α1 = 1 ° C., for example, and when the outside air is at a high temperature, the indoor temperature is not warmed so as not to cause discomfort. By introducing the outside air, the object of the present invention is to provide a cool feeling and comfort to the occupants in the room, provide an environment where the occupants can sleep and rest, and improve the cleanliness of the room air. In addition, the determination condition is set to reduce the refrigeration cycle load for the holiday operation and realize energy saving. The condition Hi ≧ β is, for example, a determination condition that is determined as β = 80%, and when the indoor humidity is abnormally high, priority is given to dehumidification of the refrigeration cycle. The condition Ti <(Tr−α2) is a determination condition that is determined, for example, as α2 = 2 ° C., and does not require introduction of outside air when the room temperature is low. At this time, naturally, the operation of the refrigeration cycle for the rest cooling operation is also stopped.

  Further, the monitoring time Ts is determined, for example, as Ts = 5 minutes, so that instantaneous fluctuation is prevented from being detected and temperature and humidity measurement can be stabilized. The time Ts is appropriately about 3 minutes to 7 minutes.

  Since the indoor temperature sensor and humidity sensor are provided in the ventilation path of the indoor unit, in order to measure indoor room temperature and indoor humidity, indoor ventilation must be performed. Therefore, when the monitoring is started, if the indoor blower is stopped, it is necessary to start the blowing and wait for a certain period of time before performing the measurement. For this reason, as shown in FIG. 4, during the air supply condition determination, at least indoor ventilation is performed, and the determination is performed in the latter half of the Ts time, Ts2.

  The times Ts1 and Ts2 are shown here as the same value, but Ts1 is the time until the temperature of the room temperature and humidity can be measured after the start of air blowing when the air blowing has stopped. Ts2 may be determined as a time during which measurement stability can be ensured, taking the actual conditions into consideration, and the total of both may be determined as Ts.

  When the monitoring is completed, a time of Tm = T3−Ts is set to determine the next monitoring timing. T3 giving the monitoring interval is set such that T3 = 30 minutes, for example, so that the start / stop of the air supply operation frequently occurs and the indoor air condition and the operation condition of the air conditioner are not disturbed. The time T3 is suitably about 20 minutes to 40 minutes, but it may be longer.

  When the above condition is satisfied and the air supply operation is stopped, it is determined whether or not the air supply operation needs to be started at the next set monitoring timing. This shows a case where after the air supply operation indicated by 2000 in the figure is stopped, the necessity of starting the air supply operation is determined at the monitoring timing indicated by 2400 in the figure.

  If the above condition is not satisfied, the air supply operation is continued. Then, it is determined whether or not it is necessary to end the air supply operation at the next set monitoring timing. This is shown in the case where the air supply operation is continued after the air supply operation for T2 time at 2200 in the figure and it is determined whether or not the air supply operation needs to be terminated at the monitoring timing indicated by 2800 in the figure. ing.

  When the air supply operation indicated by 2000 in the figure ends, the temperature and humidity are determined at the monitoring timing 2400 in the figure to determine whether or not the air supply operation needs to be started.

  When the above condition is satisfied, the time of Tm = T3−Ts is set in order to continue the absence of the air supply operation and determine the next monitoring timing. At the monitoring timing, it is determined whether or not it is necessary to start the air supply operation again (or repeatedly).

  If the above condition is not satisfied, the air supply operation at time T2 indicated by 2100 in the figure is started. And in order to determine the next monitoring timing, the time of Tm = T2-Ts is reset. Here, the operating time T2 at the time of resuming the air supply operation is determined by, for example, T2 = 60 minutes, and is an air supply / exhaust device set to an air supply amount that is less than 1/10 of the indoor air flow rate. Even if it exists, it is set as the time which can take outside air into room | room enough slowly over time so that the driving | running state of a refrigerating cycle may not be disturbed and an indoor air state may not be changed suddenly. The time T2 is suitably about 40 to 100 minutes.

  In the next monitoring timing after restarting the air supply operation indicated by 2500 in the figure, it is determined whether or not it is necessary to end the air supply operation.

  The air supply operation indicated by 2100 in the figure indicates a case where the air supply operation ends in T2 time, and the air supply operation indicated by 2200 in the figure indicates a case where the air supply operation for T2 time is further extended for T3 time. In this way, the continuation, termination and resumption of the air supply operation are controlled.

  In the present embodiment, as indicated by 3000, 3100, and 3200 in the figure, when the air supply operation is stopped, a time T4 (2 minutes to 2 minutes or more) that is sufficiently shorter than the predetermined time T1, T2, and T3 of the air supply operation. Exhaust operation in which room air is discharged to the outside is performed for a period of 5 minutes). In this exhaust operation, even if dust, dead leaves, etc. floating outside in the ventilation path of the air supply / exhaust device due to the air supply from the outside to the room may be clogged, the exhaust operation is performed following the air supply operation. By carrying out the above, they are blown away to prevent failure of the air supply / exhaust device and malfunction.

  Finally, although not shown in the figure, when the rest / air supply operation indicated by 1000 in the figure ends, this is forcibly ended even during the air supply / exhaust operation, and all the problems related to the rest / air supply operation are terminated. Of course, the operation is terminated.

  FIG. 5 is a flowchart illustrating an air supply control operation performed by the air supply / exhaust control unit 103 in FIG. 1 during the “rest cooling operation” in the air conditioner of the present embodiment.

  The processing of FIG. 5 is repeatedly called and executed at short time intervals such as 10 msec by an OS (operating system) that controls the entire operation of the logical operation of the control device, and a series of operation sequences is realized by state transition. Yes.

  Based on FIG. 5, the operation of the air supply control will be described in detail. The air supply control operation for the rest / air supply operation is started from step 5000.

  In step 5100, a signal indicating whether or not a rest operation is provided, which is provided by the rest operation control means 101 in FIG. 1, is monitored. If the in-rest signal (corresponding to 1000 in FIG. 3) is not provided, in step 5110, the indoor air blow request dedicated to the air supply control is canceled by setting the indoor air blow = “0”. This forcibly cancels an indoor air blow request dedicated to air supply control, which will be described later. Further, stop of the air supply operation is set with the air supply operation = “0”, and the air supply state is initially set to “0”. That is, when there is no signal during rest operation, since there is no air supply operation of this embodiment, all the setting states are canceled. Next, in step 5120, the air supply control process when not in a rest operation is terminated.

  The signal of indoor ventilation = “0” is a request dedicated to air supply control, and is received by the air conditioner control means 102. When there is no need for ventilation in the operation control of the air conditioner, the indoor ventilation is sent. Treated to stop.

  The air supply operation = “0” signal is received by the air supply device control unit 104 in FIG. 1, and a stop signal of the air supply operation is transmitted to the air supply device actuator 700. As a result, when the air supply operation is not performed, it is natural, but when the air supply operation is performed during the rest / air supply operation, the air supply operation at the end of the rest / air supply operation is performed. A stop is made.

  The setting of the air supply state = “0” gives a state transition of the air supply control executed when the rest / air supply operation is started. In this case, the initial state is set.

  If the rest operation control means 101 in FIG. 1 provides a rest in-operation signal in step 5100, the process proceeds to step 5200, and the state transition process of the air supply control is executed.

  The values indicating the state transition in the expression “supply state” classified in step 5200 are five types of “0”, “1”, “2”, “3”, “4”, and “0” is Air supply control start processing, “1” waits for air supply operation time or air supply condition measurement interval, “2” waits for the first half of the air supply condition determination processing, and “3” air supply condition determination processing , “4” is stop, continuation, and restart processing of the air supply control.

  In step 5200, when the air supply state = “0”, the air supply control start state at the time of rest / air supply operation is indicated, and the process proceeds to step 5300 to perform the air supply control for the initial forced air supply operation. Ki action = “1” is set. As described above, this is read by the air supply device control means 104 in FIG. 1, and various actuators of the air supply device are driven and controlled so as to perform the air supply operation. Next, a timer Tm = T1-Ts for controlling the forced operation time T1 and the air supply condition determination time Ts is set. Further, the air supply state is set to “1”, the state transition is advanced, and the processing is ended at step 5700. Next, when this air supply control process is executed, the process defined in the air supply state “1” is executed.

  Note that the timer Tm set here is subjected to timer time update processing in another processing unit by the above-described action of the OS.

  In step 5200, when the air supply state = “1”, a time waiting process is performed. That is, if the time of the timer Tm has not elapsed in step 5400, the processing is immediately terminated in step 5700 in order to wait for the time. Next, when this air supply control process is executed, the time waiting process set to the air supply state = “1” is continued.

  When the time of the timer Tm has elapsed, in step 5410, the indoor air blow = “1” is set, and the air blower is requested to the air conditioner control means 102 exclusively for the air supply control. The air conditioner control means 102 continues the air blowing as long as it is being blown indoors. However, when the air blower is not necessary and stopped in the operation control of the air conditioner, the air conditioner control unit 102 is dedicated to supplying air. Start indoor ventilation. In this case, as described above, the air is used for measuring the room temperature and the room humidity. Further, an air supply flag for determining an air supply condition = “0” is set in advance as an air supply stop schedule. Next, in order to process the air supply condition determination time, a timer Tm = Ts1 is set. This is a waiting time until the indoor temperature and the indoor humidity can be measured by the indoor air blowing when the indoor air blowing is stopped. Finally, the air supply state = “2” is set to determine the state transition, and the process is terminated in step 5700. Next, when this air supply control process is executed, the process defined as the air supply state = “2” is executed.

  In step 5200, when the air supply state = “2”, in step 5420, the passage of timer Tm = Ts 1 is awaited. If the time has elapsed, the timer Tm = Ts2 which is the determination time of the actual room temperature and room humidity is set, the supply air state = “3” is set to determine the state transition, and the processing is ended in step 5700. Next, when this air supply control process is executed, the process defined as the air supply state = “3” is executed.

In step 5200, when the air supply state = “3”, in step 5500, while waiting for the elapse of timer Tm = Ts2, in step 5510, the air supply stop condition is satisfied.
To ≧ (Ti + α1), or Hi ≧ β, or Ti <(Tr−α2).
Judgment is performed under the air supply stop condition. As a result, when the air supply stop condition is not satisfied, the air supply flag is set to “1” and the start or continuation of the air supply is set. Then, in step 5700, the process ends.

  This process is continuously executed until the timer Tm = Ts2 elapses. Therefore, if the air supply stop condition is continuously established during that time, the air supply flag = “0” as set in advance. ", Indicating the end of air supply. If the air supply stop condition is not satisfied even once, the air supply flag is set to “1” as described above.

  If it is confirmed in step 5500 that the timer Tm = Ts2 has elapsed, in step 5520, after setting the indoor air blow = “0”, the air supply state = “4” is set to determine the state transition. The process ends. Next, when this air supply control process is executed, the process defined as the air supply state = “4” is executed.

  In this way, the indoor fan = “1” set in step 5410 cancels the request as the indoor fan = “0” when the time Ts has elapsed. As described above, this is received by the air conditioner control means 102, and processing is performed so that the indoor air blow is performed exclusively for the air supply control when the indoor air blow is stopped only while the indoor air blow = "1". Is done.

  Further, in the air supply stop condition determination, the time of Ts1 in the first half of the time Ts starts air blowing when there is no air blowing, and waits for the time to stabilize the indoor temperature and indoor humidity determination. Consideration is given so that the determination can be made stably in the second half Ts2.

  In step 5200, when the air supply state = “4”, in step 5600, the state of the air supply flag determined in the process of air supply state = “3” is determined. If the air supply flag = “0”, in step 5610, the air supply operation is stopped by setting the air supply operation = “0”, and the exhaust operation time timer Th = T4 is set. The air supply operation is stopped by 104, and the exhaust operation time timer Th is monitored, and the exhaust operation is performed while the timer is set. Next, in order to wait for the next air supply condition determination interval T3, the timer Tm = T3-Ts is set, the air supply state = “1”, the state transition is changed, and the process is ended in step 5700. Next, when this air supply control process is executed, the process defined as the air supply state = “1” is executed.

  Note that the set value T4 of the exhaust time timer Th set here is a time sufficiently shorter than T3, and within the range hidden in the state transition of the air supply control described here, the air supply / exhaust device control means 104 in FIG. The exhaust operation is performed only during the set time Th of the timer.

  If it is determined in step 5600 that the air supply flag is “1”, the process proceeds to step 5620 to determine the execution state of the air supply operation. When the air supply operation = “0”, that is, when the air supply is stopped, in step 5630, the air supply operation = “1” and the resumption of the air supply operation are set, and the air supply / exhaust device control means 104 in FIG. Let the air supply operation. Next, a timer Tm = T2−Ts is set in order to specify an air supply operation time when restarting. Finally, the state transition is changed to an air supply state = “1”, and the processing is ended in step 5700. Next, when this air supply control process is executed, the process defined as the air supply state = “1” is executed.

  In step 5620, if the air supply operation = “1”, that is, if the air supply is being executed, the air supply is executed as it is, and in step 5640, in order to wait for the next air supply condition determination interval T3, the timer Tm = T3−Ts is set, the state of air supply is changed to “1”, and the state transition is changed. Next, when this air supply control process is executed, the process defined as the air supply state = “1” is executed.

  The supply / exhaust control during the rest operation shown in FIG. 3 is specifically executed by the state transition procedure described above.

  In addition, the introduction amount of the outdoor air from the outdoor to the indoor in the air supply operation described above is 10% or less as compared with the amount of air blown by the blower of the indoor unit of the air conditioner as described above. The air load is set to a range that does not adversely affect the refrigeration cycle conditions by abruptly changing the operating load of the air conditioner.
