Abstract

The invention discloses an air conditioner and an energy efficiency calculation method thereof. The energy efficiency calculation method comprises the following steps that the current working condition of the air conditioner, power consumption, power of a compressor and the shell heat dissipating capacity Qloss are obtained; the temperature t1 of a return air inlet of the compressor, the temperature t2 of an exhaust port of the compressor, the temperature t4 of the first end of an outdoor heat exchanger, the temperature t7 of the first end of an indoor heat exchanger and the air supply temperature t8 of the compressor are obtained; when the current working condition is the refrigeration condition, a refrigerant enthalpy value h1 of the return air inlet, a refrigerant enthalpy value h2 of the export port, a refrigerant enthalpy value h4 of the first end of the outdoor heat exchanger, a refrigerant enthalpy value h7 of the first end of the indoor heat exchanger, an enthalpy value h8' of a gas-state refrigerant added into the compressor and a hydraulic refrigerant enthalpy value h8'' of a flash evaporator are generated according to t1, t2, t4, t7 and t8 respectively; the refrigerating capacity is generated according to the power of the compressor, Qloss, h1, h2, h4, h7, h8' and h8''; the energy efficiency of the air conditioner is generated according to the power consumption and the refrigerating capacity, and therefore the energy efficiency of the air conditioner is detected accurately in time.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner energy efficiency calculation method, 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 current air conditioners cannot know the changes in 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 conditio...
