    By the way, when both the above-described conventional air conditioner and humidity controller are installed in the same room, the air conditioner performs an indoor air conditioning operation, while the humidity controller performs an indoor air humidity adjustment operation. I was going. In other words, the conventional air conditioner and the humidity control apparatus are each configured to perform optimum operation independently. Therefore, even if the indoor air is dehumidified by the humidity control apparatus, the air conditioner is unique. The operation was controlled to dehumidify the room air. As a result, the air conditioner dehumidifies the room air with the humidity control device, and ensures the evaporating temperature of the refrigerant in the indoor heat exchanger to ensure the dehumidification of the room air and adjust the room air temperature. Because it is necessary to control the operation under the evaporation temperature conditions that can properly perform both of the above, the set value of the evaporation temperature of the refrigerant in the indoor heat exchanger is set low, and as a result, the operating efficiency of the air conditioner is significantly reduced. There was a problem of letting it.

    This invention is made | formed in view of such a point, and it aims at improving the operating efficiency of an air conditioning apparatus while ensuring the humidity control performance of indoor air.

    The present invention relates to the evaporating temperature of the refrigerant in the indoor heat exchanger (15) of the air conditioner based on the recognition of the start / stop of the humidity controller (5) installed in the same room (2). Is adjusted.

    In the first invention, a compressor (14), an outdoor heat exchanger (16), an expansion mechanism (18), and an indoor heat exchanger (15) are connected in order, and a refrigerant circuit (13 And a control means (40) for controlling the capacity of the compressor (14) so that the refrigerant evaporation temperature of the indoor heat exchanger (15) becomes a set temperature, and the humidity control for adjusting the humidity of the indoor air An air conditioner that performs air conditioning in the same room (2) as the apparatus (5), wherein the control means (40) recognizes the start / stop state of the humidity control apparatus (5) And an evaporating temperature adjusting means (43) for adjusting the evaporating temperature of the refrigerant in the indoor heat exchanger (15) based on the on / off state of the humidity control device (5) by the recognizing means (42). .

    In the said 1st invention, while a humidity control apparatus (5) performs humidity control operation | movement of room air, an air conditioning apparatus performs indoor air conditioning. And a recognition means (42) recognizes the start / stop state of the humidity control apparatus (5) installed in the same room (2) as an air conditioning apparatus. The evaporating temperature adjusting means (43) adjusts the refrigerant evaporating temperature of the indoor heat exchanger (15) based on the recognition of the start / stop state of the humidity control device (5) by the recognizing means (42). The capacity of the compressor (14) is controlled to reach the refrigerant evaporation temperature.

    In a second aspect based on the first aspect, the evaporating temperature adjusting means (43) adjusts the evaporating temperature of the refrigerant within an air conditioning capacity range necessary for air conditioning into the room (2). It is configured.

At this time, the evaporating temperature adjusting means (43) adjusts the refrigerant evaporating temperature within an air conditioning capacity range necessary for air conditioning into the room (2). And a control means (40) controls the capacity | capacitance of a compressor (14) so that it may become the adjusted refrigerant | coolant evaporation temperature.

    According to a third invention, in the first or second invention, the evaporating temperature adjusting means (43) recognizes that the recognizing means (42) recognizes that the humidity control apparatus (5) is in a humidity control operation. The set value of the refrigerant evaporation temperature of the indoor heat exchanger (15) is increased.

    In the third invention, when the recognizing means (42) recognizes that the humidity control device (5) is in the dehumidifying operation state, the evaporating temperature adjusting means (43) reduces the capacity of the compressor (14). And evaporating temperature of the refrigerant in the indoor heat exchanger (15). When the evaporation temperature of the refrigerant in the indoor heat exchanger (15) becomes high, the indoor air becomes difficult to be dehumidified by the air conditioner. That is, the air conditioner performs air conditioning of the room air while the humidity control apparatus (5) dehumidifies the room air.

    According to the first aspect of the invention, since the recognition means (42) for recognizing the start / stop state of the humidity control device (5) is provided, the air conditioner operates in the humidity control operation (humidity control operation) of the humidity control device (5). ) Can be recognized.

Thereby, since the setting range of the evaporation temperature of the refrigerant | coolant of an indoor heat exchanger (15) can be enlarged, this evaporation temperature can be set to the temperature which the operating efficiency of an air conditioning apparatus improves. As a result, the indoor air is appropriately conditioned by the humidity control device (5), and the operating efficiency of the air conditioner can be increased.

    According to the second aspect of the invention, since the refrigerant evaporation temperature is adjusted within the range of air conditioning capacity necessary for air conditioning into the room (2), the air conditioning capacity necessary for air conditioning into the room (2). The refrigerant evaporation temperature can be adjusted while ensuring the above. Thereby, it can be reliably prevented that the air conditioning capability relating to the air conditioning to the room (2) is insufficient due to the adjustment of the refrigerant evaporation temperature. As a result, the indoor air is appropriately conditioned by the humidity control device (5), and air conditioning of the room (2) can be reliably performed by the air conditioning device.

For this reason, the dehumidifying capacity of the indoor air by the air conditioner can be lowered by the amount of the dehumidifying capacity of the indoor air of the humidity control device (5). Thereby, the set value of the evaporation temperature of the refrigerant in the indoor heat exchanger (15) can be increased. As a result, the room air can be appropriately dehumidified by the humidity control device (5), and the operating efficiency of the air conditioner can be increased.

-Driving action-
Next, the air conditioning operation of the air conditioner (10) will be described. The air conditioner (10) is switched between a cooling operation and a heating operation.

    In the heating operation, the four-way switching valve (17) is set to the second state, and the opening degree of the outdoor expansion valve (18) is appropriately set. In this state, the gas refrigerant discharged from the compressor (14) condenses into a liquid refrigerant in the indoor heat exchanger (15) and is decompressed by the outdoor expansion valve (18), and then the outdoor heat exchanger (16). Is then cycled back to the compressor (14) via an accumulator (not shown).

    In the cooling operation, the four-way switching valve (17) is set to the first state, and the opening degree of the outdoor expansion valve (18) is appropriately set. In this state, the gas refrigerant discharged from the compressor (14) condenses in the outdoor heat exchanger (16) to become a liquid refrigerant, and is decompressed by the outdoor expansion valve (18), and then the indoor heat exchanger (15) Is then cycled back to the compressor (14) via an accumulator (not shown).

    Next, the interlocking operation with the humidity control device (5) during the cooling operation will be described.

    First, when the operation of the air conditioner (10) is started, the air conditioning controller (41) updates the temperature data. This temperature data is each detection value input from the suction temperature sensor (32), the indoor heat exchange temperature sensor (34), and the remote controller, that is, the data of the indoor air suction temperature, the refrigerant evaporation temperature, and the indoor set temperature. And an air-conditioning control part (41) controls the capacity | capacitance of a compressor (14) so that the refrigerant | coolant evaporation temperature of an indoor heat exchanger (15) may become the target value of the refrigerant | coolant evaporation temperature based on the said temperature data. Specifically, the capacity of the compressor (14) is controlled so that the suction pressure of the suction pressure sensor (22) becomes a pressure value corresponding to the target value of the refrigerant evaporation temperature. In this state, the temperature of the room (2) gradually decreases, and the capacity of the compressor (14) (that is, the compressor capacity) is also reduced accordingly. At this time, in the indoor heat exchanger (15), since the indoor air is cooled when the indoor air passes through the indoor heat exchanger (15), the moisture contained in the indoor air condenses into water droplets. Become. Thereby, indoor air is dehumidified and supplied indoors.

    Here, when the humidity controller (5) starts the dehumidifying operation of the room air, the humidity controller (6) sends an operation signal to the recognition unit (42) of the air conditioning controller (40). The recognition unit (42) receives the operation signal and recognizes that the humidity control device (5) is in the dehumidifying operation. Then, the recognition unit (42) sends a recognition signal to the evaporation temperature adjustment unit (43). When receiving the recognition signal, the evaporation temperature adjusting unit (43) sets the target value of the refrigerant evaporation temperature of the air conditioning control unit (41) to a high value (for example, set to the original refrigerant evaporation temperature plus 5 ° C.). If the target value of the refrigerant evaporation temperature of the newly set indoor heat exchanger (15) satisfies the air conditioning capability necessary for adjusting the temperature of the indoor air (suction air temperature), the air conditioning control unit (41) The capacity of the compressor (14) is controlled so as to become a target value of the newly set refrigerant evaporation temperature.

-Effect of the embodiment-
According to the embodiment, since the recognition unit (42) for recognizing the start / stop state of the humidity control device (5) is provided, the air conditioner (10) can recognize the humidity control operation (humidity control operation). it can. Moreover, since the evaporating temperature of the refrigerant in the indoor heat exchanger (15) is controlled based on the recognition of the humidity control operation of the humidity control device (5), the humidity control operation according to the humidity control device (5) is performed. The air conditioner (10) can be operated at the evaporation temperature of the refrigerant. Thereby, since the setting range of the evaporation temperature of the refrigerant in the indoor heat exchanger (15) can be increased, the evaporation temperature can be set to a temperature that improves the operation efficiency of the air conditioner (10). As a result, the indoor air is appropriately conditioned and the operating efficiency of the air conditioner (10) can be increased.

    Also, the refrigerant evaporating temperature is adjusted by the evaporating temperature adjusting unit (43) within the air conditioning capacity range required for air conditioning to the room (2) of the air conditioner (10). The refrigerant evaporation temperature can be adjusted while ensuring the air conditioning capability necessary for air conditioning. Thereby, it can be reliably prevented that the air conditioning capability of the air conditioner (10) to the room (2) is insufficient due to the adjustment of the refrigerant evaporation temperature by the evaporation temperature adjusting unit (43). As a result, the indoor air is appropriately conditioned by the humidity control device (5), and air conditioning of the room (2) can be reliably performed by the air conditioning device (10).

    Furthermore, when the humidity controller (5) is in the dehumidifying operation state, the evaporation temperature adjusting means (43) increases the set value of the refrigerant evaporation temperature in the indoor heat exchanger (15). Therefore, in response to the dehumidifying operation by the humidity control device (5), that is, when the humidity control device (5) is performing the humidity control operation, the air conditioning device (10) can reduce the dehumidifying capacity. Become.
