Abstract

The invention discloses an air conditioner and an energy efficiency calculation method thereof. The method comprises the following steps: obtaining a current operating condition of an air conditioner, power consumption of the air conditioner, compressor outlet flow quantity qv, shell heat dissipating capacity Qloss, temperature t4 of a first terminal of an outdoor heat exchanger and temperature t7 of a first terminal of an indoor heat exchanger; when the current operating condition is the refrigeration operating condition, according to the t4 and t7, respectively generating a refrigerating fluid enthalpy value h4 of the first terminal of the outdoor heat exchanger and a refrigerating fluid enthalpy value h7 of the first terminal of the indoor heat exchanger; according to the compressor outlet flow quantity qv, the compressor shell heat dissipating capacity Qloss, the refrigerating fluid enthalpy value h4 of the first terminal of the outdoor heat exchanger and the refrigerating fluid enthalpy value h7 of the first terminal of the indoor heat exchanger, generating refrigerating capacity of the air conditioner; according to the power consumption and the refrigerating capacity of the air conditioner, generating the energy efficiency of the air conditioner. Therefore, the energy efficiency of the air conditioner can be accurately detected in real 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. For this reason, an object of the present invention is to propose an energy efficiency calculation method of an air conditioner, which can accurately detect the energy efficiency of the air co...
