Indoor unit of air-conditioning apparatus and air-conditioning apparatus

The invention discloses a control method of an air conditioner. The air conditioner comprises an indoor air inlet, a fresh air inlet and an air outlet; the indoor air inlet is connected with the air outlet through an inner circulating air duct, a humidification device is arranged in the inner circulating air duct, and the fresh air inlet is connected with the air outlet through a fresh air duct; and the air conditioner further comprises an air volume regulating device, and the air volume regulating device is used for regulating the inlet air volume of the inner circulating air duct and the fresh air duct. The control method of the air conditioner comprises the following steps that the humidity and the freshness of the air conditioner in the environment are obtained, the air volume ratio ofthe inner circulating air duct and the fresh air duct is determined according to the humidity and the freshness, and the opening degree of a first air volume regulating device and a second air volumeregulating device is regulated according to the air volume ratio. The invention further discloses an air conditioner and a computer readable storage medium. According to the control method of the airconditioner, the ratio between the outdoor imported air volume and the indoor circulating air volume is changed by regulating the opening degree of the air volume regulating devices of the outer circulating air inlet and the inner circulating inlet, and the target and reasonable regulating of the humidity and freshness is achieved.

Control method of air conditioner, air conditioner and computer readable storage medium

The invention provides an anti-condensation control method and device for an air conditioner. The control method comprises the steps that after it is detected that the air conditioner is in a refrigeration mode, the temperature and the relative humidity of the inner environment where an air conditioner indoor unit is located and the heat exchanger coiler temperature of the indoor unit are detected; the dew point temperature of the indoor environment where the indoor unit is located is calculated according to the indoor environment temperature and the indoor environment relative humidity; if the indoor environment temperature is larger than or equal to the indoor environment temperature preset threshold value, the indoor environment relative humidity is larger than or equal to the indoor environment relative humidity preset threshold value and the heat exchanger coil temperature of the indoor unit is smaller than the indoor environment dew point temperature, whether the first anti-condensation mode or the second anti-condensation mode of the air conditioner is started is determined according to the comparison result of the difference value of the heat exchanger coil temperature and the indoor environment dew point temperature of the indoor unit and the preset temperature difference value. By the adoption of the anti-condensation control method and device, the anti-condensation control accuracy of the air conditioner is improved, and the air conditioner is prevented from generating condensation.
