Air conditioner and energy efficiency calculating method thereof

Abstract

The invention discloses an air conditioner and an energy efficiency calculating method thereof. The method comprises the following steps of: obtaining a current working condition, power of a compressor, power consumption power of the air conditioner and heat dissipating amount Qloss of a compressor housing; obtaining a temperature t1 of an air return hole of the compressor, a temperature t2 of an air exhaust hole of the compressor, a middle temperature t6 of an indoor heat exchanger and an air supplementing temperature t8 of the compressor; generating a temperature t7 of a first end of the indoor heat exchanger and a temperature t5 of a second end of the indoor heat exchanger according to indoor environment temperatures t10 and t6; when the current working condition is a heating working condition, separately generating mixture enthalpy values h1, h2, h5 and h7, h8' and h8'' of the air return hole, the air exhaust hole, the second end of the indoor heat exchanger, the first end of the indoor heat exchanger, the supplementing compressor and a flash evaporator according to t1, t2, t5, t7 and t8; generating heating amount of the air conditioner according to power of the compressor, Qloss, h1, h2, h5, h7, h8' and h8''; and generating energy efficiency of the air conditioner according to power consumption power and heating amount 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 change of energy efficiency during operation, it is difficult to maintain a good operating state, and the heating effect 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 conditioner in rea...
