In a specific embodiment, the method mainly comprises the following steps:
when the air conditioner is in a heating mode, the humidifying function is started, the humidity control is performed by default, and the default set humidity is 45%.
For example, in heating in winter, humidification control is performed to prevent indoor air from drying. When the air conditioner is in a heating mode, the fan does not stop air, the current relative humidity is less than the set humidity (such as 40%) -5% (the specific humidity can be determined according to the comfort level in a room during testing), and the indoor unit and the outdoor unit of the air conditioner are free of faults, the first opening time T1 of the humidifying electromagnetic valve connected with the water injection pipe is controlled to be K min (the time can be set according to the time from no water to full water in the groove of the water receiving tray).
The closing time and the closing state of the waterway electromagnetic valve are controlled by signals transmitted by the float, after the humidifying mode opening condition is entered, the humidifying electromagnetic valve is opened, tap water is filled into the groove of the water receiving tray through the water filling pipe until the groove is filled with water and overflows slowly, and the humidifying electromagnetic valve is closed until the float switch is operated. At the moment, water in the groove is heated and evaporated through a high-temperature high-pressure refrigerant flowing through the heating pipe, and is blown to the indoor side along with hot air flowing through the high-temperature heat exchanger, so that the environment is humidified, and the humidifying function is realized.
When a shutdown instruction is received, or the air conditioner is switched to other modes, such as a refrigeration mode, an air supply mode or a dehumidification mode, or a fan is stopped, or the current relative humidity is greater than or equal to the set humidity (such as 45%) + 5%, or an indoor unit of the air conditioner has a fault, or an outdoor unit of the air conditioner has a fault, the humidification electromagnetic valve is closed, the humidification mode is exited, so that the humidification function is closed, and humidification is stopped.
When the air conditioner is in a refrigeration mode, a dehumidification mode or an air supply mode, the air conditioner does not perform humidity control by default, and a user sets humidity not to perform humidity control, namely, does not start a humidification function. In the three modes, the humidifying electromagnetic valve is in a normally-closed state by default, so that the humidifying function cannot be started.
