Abstract

The invention discloses an air conditioner and an energy efficiency calculation method thereof. The method comprises the following steps that power of a compressor, air conditioner power consumption, the compressor outlet flow rate qv, the shell heat dissipating capacity Qloss of the compressor, the temperature t4 of the first end of an outdoor heat exchanger and the temperature t7 of the first end of an indoor heat exchanger are obtained; when the current working condition of the air conditioner is the refrigeration condition, refrigerant enthalpy values and lubricating oil enthalpy values of the first end of the outdoor heat exchanger and the first end of the indoor heat exchanger are generated according to t4 and t7 respectively, mixture enthalpy values h4 and h7 of the first end of the outdoor heat exchanger and the first end of the indoor heat exchanger are generated according to the refrigerant enthalpy values and the lubricating oil enthalpy values of the first end of the outdoor heat exchanger and the first end of the indoor heat exchanger; the refrigerating capacity of the air conditioner is generated according to qv, Qloss, h4 and h7; finally, the energy efficiency of the air conditioner is generated according to the air conditioner power consumption and the refrigerating capacity. Therefore, the energy efficiency of the air conditioner can be detected accurately 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. 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...
