The invention discloses an air conditioner and its energy efficiency calculation method. The method comprises the following steps: obtaining the current working condition of the air conditioner, the power of the compressor and the power consumption of the air conditioner; obtaining the temperature t1 of the air return port of the compressor, Port temperature t2, outdoor heat exchanger first end temperature t4, indoor heat exchanger first end temperature t7, compressor outer wall temperature t11, and compressor air supply temperature t8; generate the heat dissipation of the compressor shell according to t2 and t11 Qloss; when the current working condition is refrigeration working condition, according to t1, t2, t4, t7 and t8, respectively generate the enthalpy value of the mixture at the return air port h1, the enthalpy value of the mixture at the exhaust port h2, and the enthalpy of the mixture at the first end of the outdoor heat exchanger value h4, the enthalpy value of the mixture at the first end of the indoor heat exchanger h7, the enthalpy value of the mixture added to the compressor h8' and the enthalpy value of the flash evaporator h8"; according to the power of the compressor, Qloss, h1, h2, h4, h7 , h8' and h8" generate the cooling capacity of the air conditioner; generate the energy efficiency of the air conditioner according to the power consumption and cooling capacity of the air conditioner.
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 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, the first 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 cond...
