BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidity control method for an air conditioner.

[0002]

2. Description of the Related Art Conventionally, as a method for operating an air conditioner and a humidifier at the same time to maintain a constant indoor humidity, as disclosed in, for example, Japanese Patent Application Laid-Open No. 61-55536, an air conditioner is disclosed. The air conditioner detects the indoor temperature and humidity and the operating state of the air conditioner, and the humidifier operation command based on the detection results is sent to the air conditioner. Is sent to the humidifier to control the operation of the humidifier so that the indoor humidity is maintained at the set value.

[0003]

However, since the air conditioner and the humidifier are separated and the indoor temperature and humidity are detected by the air conditioner, it is necessary to make the humidity distribution in the entire room uniform. It was difficult. The present invention has been made in view of the above problems, and an object of the present invention is to provide a humidity control method for an air conditioner that can make the indoor humidity distribution uniform and create a comfortable living environment.

[0004]

In order to solve the above-mentioned problems, a humidity control method of the present invention is a compressor for compressing a refrigerant to form a refrigeration cycle together with an indoor heat exchanger and an outdoor heat exchanger, and an indoor blower. And an indoor unit having therein a humidifier provided with the indoor heat exchanger and a flow control valve capable of controlling the flow of humidifying water, a humidity detecting means for detecting the humidity around the remote controller built in the remote controller, and the flow control. The set humidity storage means for storing the set humidity value for opening the valve, the comparing means for comparing and outputting the set humidity stored in the set humidity storage means and the humidity detected by the humidity detecting means, and the comparing humidity by the comparing means It comprises a judgment means for judging the operation of the flow control valve by a signal, and a selection output means for controlling the operation of the flow control valve according to the output of the judgment means.

[0005]

According to the present invention having the above-mentioned structure, the humidity detecting means of the remote controller detects the indoor humidity, and the humidifier is built in the air conditioner, whereby the humidity distribution in the entire room can be made uniform. It is a thing.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 shows a refrigeration cycle in the embodiment of the present invention, which is composed of a compressor 1, heat exchangers 2 and 3, and a four-way switching valve 4.

During the cooling operation, the refrigerant from the compressor 1 circulates in the order of the outdoor heat exchanger 2 functioning as a condenser, the expansion valve 5, and the indoor heat exchanger 3 functioning as an evaporator, and returns to the compressor 1. During the heating operation, the indoor heat exchanger 2, which functions as a condenser, the expansion valve 5, and the outdoor heat exchanger 2, which functions as an evaporator, circulate in this order and return to the compressor 1. The indoor heat exchanger 3 has an indoor fan 6 that blows the warm or cool air toward the room.
Is provided. A humidifying element 7 is arranged on the front surface of the indoor heat exchanger 3, and a water tank 8 is provided in the humidifying element 7.
Water is supplied through the water amount control valve 9.

A humidity detecting element 11 is built in the remote controller 10 to detect the humidity around the remote controller.

FIG. 3 is a main circuit diagram in the operation control unit. In the figure, the microcomputer 100 has a drive signal generating means for generating an output signal at an appropriate time according to the input value.
On the input side of the microcomputer 100, a humidity detecting element 101 provided in a remote controller, which is a humidity detecting means, and a resistor 1 whose resistance value can be changed as necessary via a comparator 109.
A humidity detecting unit constituted by 02, an arithmetic processing unit 103 for processing a signal, and resistors 104 and 105 whose resistance values can be changed as necessary are connected. On the output side,
A relay 106 that drives the water amount control valve 9 that is the driving means is configured via the switching transistor TR.

Here, comparing the configuration of FIG. 1 with the configuration of FIG. 3, the humidity detecting element 101 and the resistor 102 built into the remote controller are the humidity detecting means and the signals created by the resistors 104 and 105 are the set humidity memory of FIG. Means, the comparator 109 corresponds to comparison means, and the microcomputer 100 corresponds to determination means and selection output means.

Next, the operation of the humidity control method applied to the air conditioner having the above structure will be described with reference to the flowchart of FIG.

First, when the heating operation is started, the operation of the compressor 1 is started as shown in step 1, and the indoor humidity S is detected by the humidity detecting element 12 built in the remote controller (step 2).

Next, in the indoor control section 10, the humidity is compared with a preset humidity S1, and if S> S1, a control signal is output from the indoor control section 10 to the water volume control valve drive means 18 to control the water volume control valve. Remains closed (step 3).

When S <S1, a control signal is output from the indoor control unit 100 to the water amount control valve drive means 18, the water amount control valve is opened for a certain period of time to supply water to the humidification element from the water tank to perform the humidification operation. Do (step 4).

[0015]

As described above, according to the humidity control method for an air conditioner of the present invention, the humidity is controlled by the indoor humidity detecting means provided in the remote controller, so that the temperature distribution in the entire room is made uniform. be able to.
