The outdoor unit 21 and the indoor unit 22 are connected by a refrigerant pipe and a communication line 16 (not shown). The indoor unit 22 includes a cooling unit 22a and a cooling / heating unit 22b. The outdoor unit 21 includes a cooling outdoor unit 21 a connected to the cooling unit 22 a through the refrigerant pipe and the communication line 16, and a cooling and heating outdoor unit 21 b connected to the cooling and heating unit 22 b through the refrigerant pipe and the communication line 16. That is, the air conditioner 12 includes a cooling air conditioner 12a including a cooling outdoor unit 21a and a cooling unit 22a, and a cooling / heating air conditioner 12b including a cooling / heating outdoor unit 21b and a cooling / heating unit 22b. The air conditioner 22a is a dedicated air conditioner and dehumidifier, and is installed at a position where air is blown out in the center of the room. The air conditioner 22b is capable of cooling, dehumidifying and heating, and is installed at a position where air is blown to the peripheral part of the room (by the wall or near the window). The indoor unit 22 includes a heat exchanger 23 connected to a refrigerant pipe (not shown). The heat exchanger 23 performs air conditioning of the indoor air by exchanging heat between the refrigerant and the indoor air that is ventilated. Furthermore, a part of the cooler / warmer 22b is connected to the humidifier 11, and the humidified air from the cooler / warmer 22b can be blown out. The air conditioner 12 may be configured to be connected to one type of outdoor unit 21 in which the cooling unit 22a and the cooling / heating unit 22b are common.
[0037]
The monitoring control device 13 monitors and controls the respective operations for the plurality of humidifying devices 11 and the plurality of air conditioning devices 12. The monitoring control device 13 can transmit a dehumidification suppression command to the air conditioner 22 a of the air conditioner 12. The monitoring control device 13 is connected to the humidifying device 11 and the air conditioning device 12 by a communication line 16.
[0038]
<Operation>
〔Normal operation〕
The operation of the air conditioner 12 during normal operation will be described.
[0039]
First, when indoor air conditioning settings are input from a remote controller (not shown), a command from the remote controller is sent to the air conditioner 12. The air conditioner 22a and the air conditioner 22b perform air conditioning according to the command. For example, in the summer season, the air conditioner 22a and the air conditioner 22b perform a cooling operation or a dehumidifying operation, respectively. For example, in the winter season, the air conditioner 22a performs a cooling operation, and the air conditioner 22b performs a heating operation.
[0040]
At this time, the monitoring control device 13 monitors the operation of the air conditioner 12.
[0041]
Note that the monitoring control device 13 may perform centralized control of the air conditioner 12 without using a remote controller.
[0042]
(Dehumidification suppression)
The operation of the air conditioner 12 when the dehumidifying action is suppressed will be described. A state in which the humidity in the room is high or high occurs during or after humidification by the humidifier.
[0043]
First, the case where humidification by the humidifier 11 is performed will be described.
[0044]
When setting or reservation of indoor humidification is input by a remote controller (not shown), if the humidifier 11 is in a condition for performing a humidifying operation by a humidity sensor (not shown), the humidifier 11 starts the humidifying operation, and cooling / heating The air humidified from 22b is blown out.
[0045]
At this time, the monitoring control device 13 that monitors the operation of the humidifying device 11 detects that the humidifying device 11 is humidifying. In response to this, the monitoring controller 13 sends a dehumidification suppression command for increasing the evaporation temperature of the refrigerant in the heat exchanger 23 of the cooling device 22a for a predetermined time to the cooling air conditioner 12a. Thereby, the dehumidification effect | action in the air conditioner 22a which is performing air_conditioning | cooling is suppressed.
[0046]
Next, the case where the air conditioner 22a operates after humidification by the humidifier 11 will be described.
[0047]
When the humidifying device 11 stops after performing the humidifying operation, the monitoring control device 13 records the operation history of the humidifying device 11. When the operation of the air conditioner 22a is started within a certain time after the operation of the humidifier 11 is stopped, the dehumidifying suppression is performed so that the monitoring control device 13 increases the evaporation temperature of the refrigerant in the heat exchanger 23 of the air conditioner 22a for a predetermined time. The command is sent to the cooling air conditioner 12a. Thereby, it is suppressed that the indoor air humidified by the humidification apparatus 11 is dehumidified by the air conditioner 22a.
[0048]
<Features>
In the air conditioning system according to the present invention, when the room is humidified by the humidifying device 11, the monitoring control device 13 sends a command to the cooling air conditioning device 12a to increase the evaporation temperature of the refrigerant in the heat exchanger 23 of the cooling device 22a. Send. Thereby, it becomes possible to suppress the dehumidifying action caused by the cooling operation of the cooling device 22a.
[0049]
The monitoring control device 13 monitors the operation status of the humidifying device 11 and transmits a command when the humidifying device 11 is operated. For this reason, dehumidification can be suppressed only when it is necessary to suppress the dehumidifying action. That is, when the humidifier 11 positively humidifies the room, it is possible to suppress the dehumidifying action by the cooler 22a of the cooling air conditioner 12a. Thereby, it is possible to humidify the air-conditioning system while cooling in an office or a store, so that the humidification effect is not impaired.
[0050]
Further, unlike the devices disclosed in Patent Documents 1 to 3, the monitoring control device 13 does not perform transmission based on a sensor such as a dew point temperature sensor or a dew condensation water sensor to transmit a dehumidification suppression command. For this reason, there are advantages such as no sensor cost, no sensor maintenance, and no malfunction due to a sensor failure, compared to the conventional example.
[0051]
<Other Example 1>
Another embodiment of the air conditioning system according to the present invention is shown in FIG.
[0052]
Here, the humidifier 31 is not connected to the communication line 16 and is installed in the room independently. The humidifier 31 is automatically operated according to the humidity in the room.
[0053]
The monitoring control device 13 is connected to the remote monitoring server 41 of the remote monitoring center C via the communication network 40. The remote monitoring server 41 is connected to the plurality of monitoring control devices 13 and monitors the plurality of air conditioning devices 12 via the monitoring control device 13. The remote monitoring server 41 can receive weather information from a weather information server (not shown) and transmit it to the monitoring control device 13.
[0054]
(Dehumidification suppression)
The humidifying device 31 performs a humidifying operation when the indoor humidity decreases. The monitoring control device 13 is not connected to the humidifying device 31, but estimates the operation of the humidifying device 31 based on the weather information from the remote monitoring server 41. As weather information, a predicted value of an outdoor discomfort index is used. For example, when the predicted value of the discomfort index in the daytime is 60 or less, the monitoring control device 13 predicts that the humidifying device 31 will operate, and increases the evaporation temperature of the refrigerant in the heat exchanger 23 of the cooling device 22a for a predetermined time. The dehumidification suppression command to be sent is sent to the cooling air conditioner 12a. Thereby, the dehumidification effect | action in the air conditioner 22a which is performing air_conditioning | cooling is suppressed.
[0055]
[Characteristics of Other Embodiment 1]
The other features of the first embodiment shown in FIG. 2 are that the monitoring control device 13 and the humidifying device 31 are not connected, and that the monitoring control device 13 can acquire weather information, and based on this weather information. The point which estimates the driving | operation of the humidifier 31 and the above two points are mentioned.
[0056]
Since the humidifier 31 does not communicate with the monitoring controller 13, the humidifier 31 does not require a communication function. For this reason, even when the simple humidifier 31 is installed indoors, the monitoring controller 13 predicts the operation of the humidifier 31 based on weather information, and suppresses the dehumidifying action by the air conditioner 22a at an appropriate time. can do.
[0057]
Moreover, since the monitoring control apparatus 13 can acquire weather information, it is not necessary to install a sensor for measuring outdoor humidity. For this reason, there are advantages such as no sensor cost, no sensor maintenance, and no malfunction due to sensor failure.
[0058]
Furthermore, in the other embodiment 1, even when the humidifying device 31 is not installed or is not operated, dehumidification in the room can be suppressed. That is, when the humidifying device 31 is not installed or operated, the outdoor humidity tends to affect the indoor humidity. For this reason, when the monitoring and control apparatus 13 obtains an expectation that the outdoor is high humidity from the weather information, there is a high possibility that the room will also be high. At this time, if the air conditioner 22a is operated, a dehumidifying action may occur. In such a case, when the monitoring control device 13 sends a dehumidification suppression command for increasing the evaporation temperature of the refrigerant in the heat exchanger 23 of the cooling device 22a to the cooling air conditioner 12a, the dehumidifying action in the cooling device 22a is suppressed. Will be. Thereby, indoor dehumidification is suppressed.
[0059]
<Other Example 2>
In another embodiment 1 of the air conditioning system according to the present invention, the monitoring control device 13 acquires weather information from the remote monitoring server 41, but the weather information may be acquired by other means. For example, the monitoring control device 13 may directly connect to a weather information server that provides weather information, and acquire weather information.
