  By the way, when the air conditioner and the humidity control apparatus are provided in the same indoor space, the air conditioner can distribute the temperature-controlled air throughout the room because the air volume of the air supplied to the room is relatively large. However, the humidity control apparatus often has a relatively small amount of supplied air, and there is a problem that it is difficult to distribute the humidity-adjusted air into the room.

  For example, in a humidity control apparatus that ventilates a room while adjusting the humidity of the room as described above, the air volume of the exhaust air increases when the air volume of the supply air is increased, so that the air whose humidity has been adjusted is discharged to the outside. . Therefore, the air volume of the supply air cannot be increased, and it is difficult to distribute the humidity-adjusted air into the room. For this reason, even if the humidity-adjusted air is supplied to the room, the humidity-adjusted air may remain, and the comfort of the occupant is not improved or the indoor humidity adjustment is insufficient. There is a problem that the humidity sensor senses and a useless humidity adjustment operation is performed to compensate for it.

  The present invention has been made in view of such points, and an object of the present invention is to adjust the humidity by the humidity control device in the air conditioning system including the humidity control device and the air conditioning device for the same indoor space. The purpose of this is to improve the comfort of the room efficiently by spreading the air in the room.

  The first aspect of the invention is a humidity control device (10) that performs humidity control operation for supplying the indoor air after adjusting the humidity, and a temperature control operation for supplying the indoor air after adjusting the temperature of the acquired indoor air. The target is an air conditioning system (1) equipped with an air conditioning device (20). In the air conditioner (20), it is possible to switch between the air blowing operation for blowing the taken indoor air into the room as it is and the temperature control operation, and the air conditioner is in operation. Control means (41, 42) capable of executing a stirring operation for causing the air conditioner (20) to perform a blowing operation in a state where the temperature adjustment operation is stopped in (20) is provided.

  In the first aspect of the invention, the control means (41, 42) is configured to be able to execute the stirring operation while the humidity control device (10) is in operation and the air conditioning device (20) has stopped the temperature control operation. ing. When the control means (41, 42) performs the stirring operation, the air conditioner (20) performs a blowing operation for blowing the taken indoor air into the room as it is. And if ventilation operation is performed by an air conditioner (20), indoor air will be stirred by the air which this air conditioner (20) blows off. The air conditioner (20) performs the air blowing operation when the stirring operation is executed by the control means (41, 42), for example, even when the room temperature is a set value and the temperature adjustment operation is not necessary.

  According to a second invention, in the first invention, the air conditioner (20) is configured to be capable of changing a blowing direction of air supplied to the room, and the control means (41, 42) is configured to perform the stirring operation. In this case, the air blowing direction of the air conditioner (20) is changed.

  In 2nd invention, when a control means (41, 42) performs stirring operation, it makes a humidity control apparatus (10) perform ventilation operation | movement, changing the blowing direction of air. When the air blowing direction changes during the air blowing operation, air is blown out in various directions from the air conditioner (20), and the indoor air environment is made more uniform.

  According to a third aspect of the present invention, in the first or second aspect, the humidity control apparatus (10) performing the humidity control operation adjusts the humidity of the taken outdoor air and supplies the outdoor air to the room at the same time. To discharge.

  In the third invention, the humidity control device (10) performs ventilation for exchanging indoor and outdoor air as well as adjusting the humidity in the room. Thereby, in the humidity control operation of the humidity control apparatus (10), dirty air in the room is discharged to the outside of the room, and fresh air is introduced from the outside to the room.

  According to a fourth invention, in any one of the first to third inventions, the control means (41, 42) performs the air blowing operation at a preset time interval during the stirring operation. Let (20) do.

  In 4th invention, if a control means (41,42) performs stirring operation, the ventilation operation | movement of an air conditioner (20) will be performed at the preset time interval. The indoor air is agitated each time the air conditioner (20) is blown.

  According to a fifth invention, in any one of the first to fourth inventions, the control means (41, 42) includes the indoor air and the air supplied to the room from the humidity control device (10). The start or stop of the stirring operation is determined based on the difference in temperature or humidity.

  In the fifth invention, the start or stop of the stirring operation is determined based on the difference in temperature or humidity between the room air and the air supplied from the humidity controller (10) to the room. Here, if there is a temperature or humidity difference between the indoor air and the air supplied to the room from the humidity control device (10), the location near the humidity control device (10) and the humidity control device ( The difference in temperature or humidity between locations away from 10) is likely to increase. Therefore, in the fifth aspect of the invention, it is determined whether or not the room air needs to be stirred from the difference in temperature or humidity between the room air and the air supplied to the room from the humidity control device (10). ing.

  According to a sixth invention, in any one of the first to fourth inventions, the air conditioner (20) includes suction temperature detecting means for detecting the temperature of air taken in from the room, and the control means (41, 42). ) Determines the stop of the stirring operation based on the amount of change in the detected value of the suction temperature detecting means.

  In the sixth invention, the stop of the stirring operation is determined based on the amount of change in the detected value of the suction temperature detecting means. Here, when the indoor air is not sufficiently stirred, the temperature distribution in the room may be uneven. When the temperature distribution in the room is not uniform, the temperature of the air taken in by the air conditioner (20) is not constant, and the detected value of the suction temperature detecting means changes in a relatively short time. That is, from the amount of change in the detected value of the suction temperature detecting means, it is estimated whether the indoor temperature distribution is in a non-uniform state. In the sixth aspect of the invention, the stop of the stirring operation is determined based on this estimation.

  According to a seventh invention, in the third invention, the humidity control device (10) includes return air state detection means for detecting the temperature or humidity of air taken in from the room, and the control means (41, 42) The start or stop of the stirring operation is determined based on the amount of change in the detection value of the return air state detection means.

  In the seventh invention, the start or stop of the stirring operation is determined based on the amount of change in the detection value of the return air state detection means. Here, when the indoor air is not sufficiently stirred, the indoor temperature or humidity distribution may be uneven. When the indoor temperature or humidity distribution is not uniform, the temperature or humidity of the air taken in by the humidity control device (10) is not constant, and changes to the detection value of the return air state detection means in a relatively short time. Is seen. That is, from the amount of change in the detection value of the return air state detection means, it is estimated whether the indoor temperature or humidity distribution is in a non-uniform state. In the seventh invention, the start or stop of the stirring operation is determined based on this estimation.

  According to an eighth invention, in any one of the first to seventh inventions, the humidity control device (10) is connected to an adsorption heat exchanger (51, 52) carrying an adsorbent to perform a refrigeration cycle. A refrigerant circuit (50) for performing heating, cooling or cooling the adsorbent of the adsorption heat exchanger (51, 52) with the refrigerant of the refrigerant circuit (50), and adjusting the humidity of the air in contact with the adsorbent Supply indoors.

  In the eighth invention, when the humidity control operation is performed in the humidity control apparatus (10), moisture is desorbed from the adsorbent of the heated adsorption heat exchanger (51, 52), and the cooled adsorption heat exchanger is cooled. The adsorbent (51, 52) adsorbs moisture. Thereby, the air which contacts the heated adsorption heat exchanger (51, 52) is humidified, and the air which contacts the cooled adsorption heat exchanger (51, 52) is dehumidified.

  According to a ninth invention, in the eighth invention, the humidity control device (10) further includes an air supply state detection means for detecting a temperature or humidity of air supplied to the room, and the control means (41, 42) includes: The start or stop of the stirring operation is determined based on the amount of change in the detected value of the air supply state detecting means.

  In the ninth invention, the start or stop of the stirring operation is determined based on the amount of change in the detected value of the air supply state detecting means. Here, when the temperature or humidity of the air taken in by the humidity control device (10) changes, the heat absorption amount of the refrigerant and the moisture adsorption amount of the adsorbent in the adsorption heat exchanger (51, 52) change. And since the driving | running state of a humidity control apparatus (10) also changes according to it, the temperature or humidity of the air supplied indoors from a humidity control apparatus (10) also changes. That is, in the air supply state detection means, a change in the temperature or humidity of the air taken in by the humidity control device (10) is indirectly detected. As described above, since the temperature or humidity distribution in the room is inferred from the amount of change in the temperature or humidity of the air taken in the humidity control apparatus (10), in the ninth invention Then, this estimation is performed from the amount of change in the detection value of the air supply state detection means, and the start or stop of the stirring operation is determined.

  In the present invention, the control means (41, 42) can execute the stirring operation for causing the air conditioner (20) to perform the air blowing operation. When the stirring operation is executed, the air blown out from the air conditioner (20). The air in the room is agitated. The air conditioner (20) performs the air blowing operation when the stirring operation is executed by the control means (41, 42) even when the temperature adjustment operation is stopped. As a result, the air whose humidity has been adjusted by the humidity control device (10) reaches the interior without staying. Then, the air whose humidity has been adjusted by the humidity control device (10) is mixed with the indoor air in a wider range. Therefore, since the indoor air environment can be made uniform, the indoor comfort can be improved efficiently.

  Moreover, in the said 2nd invention, the air environment in a room is made more uniform by changing the blowing direction of air in the case of the ventilation operation | movement of an air conditioner (20). Thereby, indoor comfort can be improved more efficiently.

  Moreover, in the said 3rd invention, a humidity control apparatus (10) is comprised so that indoor ventilation may be performed with indoor humidity control. Here, in the humidity control apparatus (10) that performs ventilation, if the ventilation rate is increased in order to spread the humidity-adjusted air into the room, the air whose humidity has been adjusted will be discharged to the outside. Ventilation volume is relatively small. However, according to the third aspect of the invention, when the control means (41, 42) performs the stirring operation, the indoor air is stirred by the air blown out by the air conditioner (20) that performs the blowing operation. Therefore, even in the case of a humidity control device (10) that performs ventilation, which has been particularly difficult to distribute humidity-adjusted air into the room in the past, the humidity-adjusted air goes into the room without stagnation. Since it can extend, indoor comfort can be improved efficiently.

  In the fifth aspect of the invention, it is determined whether or not the room air needs to be stirred from the difference in temperature or humidity between the room air and the air supplied to the room from the humidity control device (10). ing. If the difference in temperature or humidity between the location close to the humidity control device (10) and the location away from the humidity control device (10) is likely to increase, it is necessary to agitate the room air. 41, 42), the stirring operation is executed. Further, when it is not necessary to stir the indoor air, the stirring operation is stopped by the control means (41, 42). Therefore, the air blowing operation of the air conditioner (20) for stirring the indoor air can be efficiently performed.

  In the sixth aspect of the invention, it is estimated from the amount of change in the detected value of the suction temperature detecting means whether the indoor temperature distribution is in a non-uniform state. And based on this estimation result, the stop of stirring operation is judged. Thereby, since it is possible to appropriately determine whether to stop the air blowing operation of the air conditioner (20), the air blowing operation of the air conditioner (20) for stirring the indoor air can be efficiently performed.

  In the seventh aspect of the invention, it is estimated from the amount of change in the detection value of the return air state detection means whether the indoor temperature or humidity distribution is in a non-uniform state. And based on this estimation result, the start or stop of stirring operation is judged. Thereby, since the judgment of the start or stop of the air blowing operation of the air conditioner (20) can be appropriately performed, the air blowing operation of the air conditioner (20) for stirring the indoor air can be efficiently performed. .

  In the ninth aspect of the invention, it is estimated whether or not the indoor temperature or humidity distribution is in a non-uniform state from the amount of change in the detected value of the air supply state detecting means. And based on this estimation result, the start or stop of stirring operation is judged. Thereby, since the judgment of the start or stop of the air blowing operation of the air conditioner (20) can be appropriately performed, the air blowing operation of the air conditioner (20) for stirring the indoor air can be efficiently performed. .

-Driving action-
<Operation of humidity control device>
In the humidity control apparatus (10) of the present embodiment, a dehumidifying operation and a humidifying operation are performed. During the dehumidifying or humidifying operation, the humidity control device (10) adjusts the humidity of the outdoor air (OA) that has been taken in and supplies it to the room as supply air (SA), and at the same time discharges the taken indoor air (RA). Discharge outside as air (EA). That is, the humidity control apparatus (10) during the dehumidifying operation or the humidifying operation performs indoor ventilation. Further, the humidity control apparatus (10) alternately repeats the first operation and the second operation at a predetermined time interval (for example, every 3 minutes) during both the dehumidifying operation and the humidifying operation.

  The humidity control apparatus (10) takes in outdoor air (OA) as the first air and indoor air (RA) as the second air during the dehumidifying operation. The humidity control apparatus (10) takes in indoor air (RA) as the first air and outdoor air (OA) as the second air during the humidifying operation.

When the compressor (53) is operated, the refrigerant circulates in the refrigerant circuit (50). Specifically, the refrigerant discharged from the compressor (53) dissipates heat in the first adsorption heat exchanger (51) and condenses. The refrigerant condensed in the first adsorption heat exchanger (51) is decompressed when passing through the electric expansion valve (55), and then absorbs heat in the second adsorption heat exchanger (52) and evaporates. The refrigerant evaporated in the second adsorption heat exchanger (52) is sucked into the compressor (53), compressed, and discharged again from the compressor (53).

  Thus, in the refrigerant circuit (50) during the first operation, the first adsorption heat exchanger (51) serves as a condenser and the second adsorption heat exchanger (52) serves as an evaporator. In the first adsorption heat exchanger (51) serving as a condenser, the adsorbent on the surface of the fin (57) is heated by the refrigerant in the heat transfer tube (58), and in the second adsorption heat exchanger (52) serving as an evaporator, the fin (57) The adsorbent on the surface is cooled by the refrigerant in the heat transfer tube (58).

  As shown in FIG. 2B, in the refrigerant circuit (50) during the second operation, the four-way switching valve (54) is set to the second state. When the compressor (53) is operated, the refrigerant circulates in the refrigerant circuit (50). Specifically, the refrigerant discharged from the compressor (53) dissipates heat and condenses in the second adsorption heat exchanger (52). The refrigerant condensed in the second adsorption heat exchanger (52) is depressurized when passing through the electric expansion valve (55), and thereafter absorbs heat in the first adsorption heat exchanger (51) and evaporates. The refrigerant evaporated in the first adsorption heat exchanger (51) is sucked into the compressor (53), compressed, and discharged again from the compressor (53).

  Thus, in the refrigerant circuit (50), the second adsorption heat exchanger (52) serves as a condenser, and the first adsorption heat exchanger (51) serves as an evaporator. In the first adsorption heat exchanger (51) serving as an evaporator, the adsorbent on the surface of the fin (57) is cooled by the refrigerant in the heat transfer tube (58), and in the second adsorption heat exchanger (52) serving as a condenser, the fin (57) The adsorbent on the surface is heated by the refrigerant in the heat transfer tube (58). The first air passing through the first adsorption heat exchanger (51) is adsorbed by the adsorbent in which the moisture therein is cooled, and the first air is cooled. The second air passing through the second adsorption heat exchanger (52) is heated while being given moisture desorbed from the heated adsorbent.

  When the dehumidifying operation is in progress, the first air dehumidified and cooled by the first adsorption heat exchanger (51) is supplied to the room, and the moisture desorbed from the second adsorption heat exchanger (52) 2 Exhaust with the air. On the other hand, during the humidifying operation, the second air heated and humidified by the second adsorption heat exchanger (52) is supplied into the room, and the first adsorption heat exchanger (51) is deprived of moisture. 1 Air is discharged outside the room.

In the humidity control apparatus (10), when the desired room humidity is input to the humidity input section, the humidity control section (41) sets the desired room humidity as the target humidity, and the desired room temperature is set to the temperature input section. Is input, the humidity control unit (41) sets the desired room temperature to the target temperature. In addition, the humidity control unit (41) includes the detected temperatures detected by the inside air temperature sensor, the supply air temperature sensor, and the outside air temperature sensor of the humidity control device (10), the inside air humidity sensor, the supply air humidity sensor, and the outside air. The detected humidity detected by the humidity sensor is received.

  The humidity control unit (41) calculates the absolute humidity at the temperature and humidity from the target temperature and the target humidity by the calculation unit (33), and sets the calculated absolute humidity as the target absolute humidity. The computing unit (33) calculates the absolute humidity of the outdoor air (OA) from the detected temperature of the outdoor temperature sensor and the detected humidity of the outdoor air humidity sensor. Further, the calculation unit (33) calculates the absolute humidity of the room air (RA) from the detected temperature of the room temperature sensor and the detected humidity of the room temperature humidity sensor. Based on the absolute humidity of the outdoor air (OA) and indoor air (RA) and the target absolute humidity, the humidity control unit (41) adjusts the humidity control device ( 10) Control the humidity control capacity. The humidity control capacity of the humidity control apparatus (10) is controlled, for example, by changing the refrigerant circulation rate by changing the operating frequency of the compressor (53).

  Next, control of the temperature adjustment operation of the air conditioner (20) will be described. In the air conditioner (20), when a desired room temperature is input to the input unit, the air conditioning control unit (42) sets the desired room temperature as a target temperature on the air conditioning side. Moreover, an air-conditioning control part (42) receives the detected temperature detected with the suction air temperature sensor.

  And an air-conditioning control part (42) adjusts the temperature control capability of an air conditioner (20) so that the detected temperature of an intake air temperature sensor approaches the target temperature by the side of an air conditioning. Control of the temperature control capability of the air conditioner (20) is performed, for example, by changing the operation frequency of the compressor (63) to change the refrigerant circulation amount. In addition, the air conditioning control unit (42), when the temperature detected by the intake air temperature sensor exceeds the target temperature (a state below the target temperature in the cooling operation and a state above the target temperature in the heating operation), the compressor (63 Set the air conditioner (20) in the thermo-off state to stop.

  Next, the stirring operation in the humidity control unit (41) will be described.

  The humidity control unit (41) activates the compressor (53) and starts the humidity control operation of the humidity control device (10) when the resident inputs the start of the humidity control operation of the humidity control device (10). Let it begin. Then, when a predetermined time (for example, 5 minutes) elapses from the start of the humidity control operation of the humidity control device (10), the humidity control unit (41) determines whether to start the stirring operation. The determination of the start of the stirring operation is made based on the difference in temperature or humidity between “room air” and “supply air (SA) supplied from the humidity controller (10) to the room”. The humidity control unit (41) controls the humidity when there is a difference in temperature or humidity between the “room air” and the “supply air (SA) supplied to the room from the humidity control device (10)”. It is determined that the difference in temperature or humidity is likely to increase between a location close to the device (10) and a location remote from the humidity control device (10), and the start of the stirring operation is determined.

  Specifically, the humidity control unit (41) is “a first condition where the difference between the detected temperature of the inside air temperature sensor and the detected temperature of the supply air temperature sensor is equal to or higher than a first set value (for example, 5 ° C.)”, The agitation operation is started when any of the conditions “the second condition in which the difference between the detected humidity of the inside air humidity sensor and the detected humidity of the supply air humidity sensor is equal to or greater than a second set value (for example, 20%)” To do. When the humidity control unit (41) determines the start of the stirring operation, the humidity control unit (41) transmits a command to start the air blowing operation of the air conditioner (20) to the air conditioning control unit (42). When receiving the start command, the air conditioning control unit (42) activates the indoor fan (25) of the air conditioner (20) to start the air blowing operation even if there is no input from the occupant.

  In addition, the humidity control unit (41) determines whether or not to stop the stirring operation at a predetermined interval (for example, 1 minute) during the execution of the stirring operation. Specifically, the humidity control unit (41) determines to stop the stirring operation when both the first condition and the second condition are not satisfied. When the humidity control unit (41) determines to stop the stirring operation, the humidity control unit (41) transmits a command to stop the air blowing operation of the air conditioner (20) to the air conditioning control unit (42). When receiving the stop command, the air conditioning control unit (42) stops the indoor fan (25) of the air conditioner (20) and terminates the air blowing operation even if there is no input from the occupant.

  Further, the humidity control unit (41) determines whether or not to restart the stirring operation at a predetermined interval (for example, 1 minute) when the humidity control operation is continued in the humidity control apparatus (10) after the stirring operation is stopped. Make a decision. The humidity control unit (41) resumes the stirring operation when either the first condition or the second condition is satisfied.

  The humidity control unit (41) stops the air blowing operation of the air conditioner (20) if the stirring operation is being performed when the humidity control operation of the humidity control device (10) is terminated by the resident's input. A command is transmitted to an air-conditioning control part (42). When receiving the stop command, the air conditioning controller (42) ends the air blowing operation of the air conditioner (20).

The humidity control unit (41) causes the humidity control device (10) to start the humidity control operation, and transmits an air blow operation start command from the air conditioning device (20) to the air conditioning control unit (42). When receiving the start command, the air conditioning control unit (42) activates the indoor fan (25) of the air conditioner (20) to start the air blowing operation without any input from the occupant.

  This air conditioner (20) is set in advance so as to execute the air blowing operation in an intermittent operation that repeats the operation and the stop at a predetermined time interval when the air blowing operation is executed in accordance with a command from the humidity control unit (41). Has been. Specifically, when receiving the start command from the humidity control unit (41), the air conditioning control unit (42) causes the air conditioner (20) to perform a blowing operation for a first predetermined time (for example, 5 minutes). The operation of stopping for a second predetermined time (for example, 3 minutes) is repeated.

  When the humidity control unit (41) terminates the humidity control operation of the humidity control device (10) by the resident's input, the air conditioning control unit (42) sends a command to stop the air blowing operation to the air conditioning control unit (42).

In the third modification, when a predetermined time (for example, 5 minutes) elapses from the start of the humidity control operation of the humidity control apparatus (10), the stirring operation is automatically started by the humidity control unit (41). Then, the humidity control unit (41) determines whether to stop or restart the stirring operation based on the amount of change in the temperature or humidity of the indoor air (RA) taken in from the room by the humidity controller (10). With regard to the air conditioning system (1) of the third modified example, the humidity control operation of the humidity control device (10) from the state where the humidity control operation of the humidity control device (10) and the temperature control operation of the air conditioning device (20) are both stopped. The operation when starting is described (see FIG. 7).

  When there is an input from the occupant to start the humidity control operation of the humidity control device (10), the humidity control unit (41) first causes the humidity control device (10) to start the humidity control operation. Then, when a predetermined time (for example, 5 minutes) elapses from the start of the humidity control operation, the humidity control unit (41) starts the stirring operation, and the humidity control unit (41) performs the air blowing operation of the air conditioner (20). A start command is transmitted to an air-conditioning control part (42). When receiving the start command, the air conditioning control unit (42) activates the indoor fan (25) of the air conditioner (20) to start the air blowing operation even if there is no input from the occupant.

  In addition, the humidity control unit (41) determines whether or not to stop the stirring operation at a predetermined time interval (for example, 1 minute) during the execution of the stirring operation. Specifically, the humidity control unit (41) sets the “fifth condition in which the amount of change in the detected value of the inside air humidity sensor within a predetermined time is below the fifth set value” and “detection of the inside air temperature sensor within the predetermined time”. When both of the conditions “sixth condition in which the amount of change in value falls below the sixth set value” are satisfied, the stirring operation is stopped.

  The humidity control unit (41) estimates whether or not the indoor temperature or humidity distribution is in a non-uniform state from the amount of change in the detected values of the room air humidity sensor and the room temperature sensor within a predetermined time. When the humidity control unit (41) estimates that the indoor temperature or humidity distribution is not in a non-uniform state, it stops the stirring operation.

  When the humidity control unit (41) determines to stop the stirring operation, the humidity control unit (41) transmits a command to stop the air blowing operation of the air conditioner (20) to the air conditioning control unit (42). When receiving the stop command, the air conditioning control unit (42) stops the indoor fan (25) of the air conditioner (20) and terminates the air blowing operation even if there is no input from the occupant.

  Further, the humidity control unit (41) determines whether or not to restart the stirring operation at a predetermined interval (for example, 1 minute) when the humidity control operation is continued in the humidity control apparatus (10) after the stirring operation is stopped. Make a decision. The humidity control unit (41) restarts the stirring operation when either the fifth condition or the sixth condition is not satisfied.

  It should be noted that the “amount of change in the detected value of the intake air temperature sensor within a predetermined time period” may be used to determine whether to stop the stirring operation. Further, the “amount of change in the detected values of the supply air temperature sensor and the supply air humidity sensor within a predetermined time” may be used to determine whether to stop or restart the stirring operation. The estimation of whether the indoor temperature or humidity distribution is in a non-uniform state can also be made based on the amount of change in these detected values.

  In this modification 3, it is estimated whether the indoor temperature or humidity distribution is in a non-uniform state from the amount of change in the detected values of the room air humidity sensor and the internal temperature sensor. And based on this estimation result, the start or stop of stirring operation is judged. Thereby, since the judgment of the start or stop of the air blowing operation of the air conditioner (20) can be appropriately performed, the air blowing operation of the air conditioner (20) for stirring the indoor air can be efficiently performed. .
