Abstract

The invention discloses an air conditioner and an energy efficiency calculation method thereof. The method comprises the following steps that the current working condition of the air conditioner, power of a compressor and air conditioner power consumption are obtained; the temperature t2 of an exhaust port of the compressor, the temperature t4 of the first end of an outdoor heat exchanger, the temperature t6 of the middle of an indoor heat exchanger and the indoor environment temperature t9 are obtained; the temperature t1 of a return air inlet of the compressor is generated according to t9 and t4, and the temperature t7 of the first end of the indoor heat exchanger is generated according to t9 and t6; when the current working condition of the air conditioner is the refrigeration condition, refrigerant enthalpy values and lubricating oil enthalpy values of the return air inlet, the exhaust port, the first end of the outdoor heat exchanger and the first end of the indoor heat exchanger are correspondingly generated according to t1, t2, t4 and t7; mixture enthalpy values h1, h2, h4 and h7 of all positions are generated according to the refrigerant enthalpy values and the lubricating oil enthalpy values of all the positions; the refrigerating capacity of the air conditioner is generated according to the power of the compressor, h1, h2, h4 and h7; the energy efficiency of the air conditioner is generated according to the air conditioner power consumption and the refrigerating capacity.

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, 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 conditioner...
