The invention discloses an air conditioner and an energy efficiency calculation method thereof. The energy efficiency calculation method comprises the following steps: acquiring the current working condition and power consumption of the air conditioner and the power of the compressor; acquiring the pressure on the low pressure side and the pressure on the high pressure side; acquiring the temperature t1 at the return air inlet of the compressor, the temperature t2 at the air outlet of the compressor, the pressure on the lower pressure side, the temperature t4 at the first end of an outdoor heat exchanger, the temperature t7 at the first end of an indoor heat exchanger and the air supplement temperature t8 of the compressor; when the current working condition is the refrigeration condition, generating the following values according to the pressures, t1, t2, t4, t7 and t8: namely the enthalpy value h1 of a refrigerant at the return air inlet, the enthalpy value h2 of the refrigerant at the air outlet, the enthalpy value h4 of the refrigerant at the first end of the outdoor heat exchanger, the enthalpy value h7 of the refrigerant at the first end of the indoor heat exchanger, the enthalpy value h8' of a gaseous refrigerant added to the compressor and the enthalpy value h8'' of a liquid refrigerant of a flash evaporator; generating the refrigerating capacity according to the power of the compressor, h1, h2, h4, h7, h8' and h8''; and further generating the energy efficiency of the air conditioner according to the power consumption and the refrigerating capacity of the air conditioner. According to the air conditioner and the energy efficiency calculation method thereof, the energy efficiency of the air conditioner can be detected accurately.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an energy efficiency calculation method of an air conditioner, an air conditioner and a non-transitory computer-readable storage medium. Background technique [0002] Whether the air conditioner is energy-saving and comfortable is a problem that users are more concerned about. [0003] Since the air conditioner in the related art cannot know the change of energy efficiency during operation, it is difficult to maintain a good operating state, and the cooling and heating effects and energy-saving performance are not ideal. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, an object of the present invention is to provide an energy efficiency calculation method of an air conditioner, which can accurately detect the energy efficiency of the air co...
