Abstract
The application discloses an air conditioner, which comprises a refrigerant circuit composed of a compressor, a condenser, a throttling device and an evaporator, an indoor fan and an indoor temperature detecting device for detecting an indoor temperature. After receiving a first signal, a first rotating speed of the indoor fan, a first operating frequency of the compressor and the indoor temperature are obtained, a first air volume entering an indoor heat exchanger is obtained based on the first rotating speed and the indoor temperature, a first latent heat quantity is obtained based on the first operating frequency, the indoor temperature and the first air volume, a first sensible heat quantity is obtained based on the first operating frequency and the first latent heat quantity, an air conditioner system capacity value is obtained based on the first latent heat quantity and the first sensible heat quantity, and the operating frequency of the compressor is adjusted according to the relationship between the air conditioner system capacity value and a preset capacity range. Without additional hardware sensors, the latent heat exchange quantity and the sensible heat exchange quantity of the air conditioner are obtained by calculation based on the operating frequency of the compressor, the rotating speed of the fan and the indoor temperature, and then the air conditioner system capacity value for displaying the air conditioner system capacity is obtained, so that the air conditioner has simple structure and high accuracy.
