An air conditioning apparatus

Abstract

The application discloses an air conditioner device, comprising an evaporation temperature detection module, the low pressure of the air conditioner device is determined as follows: detecting the evaporation temperature signal; determining the evaporation temperature according to the evaporation temperature signal; obtaining the number of matches and the length of the pipe of the air conditioner device, and obtaining the pressure correction coefficient corresponding to the air conditioner device from the pressure correction coefficient relationship corresponding to the number of matches and the length of the pipe of the air conditioner device determined in advance; determining the low pressure of the air conditioner device according to the evaporation temperature and the pressure correction coefficient. The air conditioner device determines the pressure correction relationship coefficient according to the number of matches and the length of the pipe of the air conditioner device and the relationship between the low pressure and the evaporation temperature in advance, when the air conditioner device is running, the pressure correction relationship coefficient is determined according to the number of matches and the length of the pipe of the air conditioner device, and then the low pressure is determined according to the evaporation temperature and the pressure correction relationship coefficient, thus, the determined low pressure can be adapted to the refrigerating capacity of the air conditioner device and the actual installation, and the determined low pressure is more accurate.
