Air conditioner and energy efficiency calculation method thereof

Abstract

The invention discloses an air conditioner and an energy efficiency calculation method thereof. The method comprises the following steps: current working condition of the air conditioner, power of a compressor and power consumption power of the air conditioner are acquired; heat dissipation capacity Qloss of a shell of the compressor is acquired; a compressor air return opening temperature t1, a compressor exhaust opening temperature t2, a temperature t6 of a middle part of an indoor heat exchanger, a temperature t7 of a first end of the indoor heat exchanger and an indoor environment temperature t9 are obtained; a temperature t5 of a second end of the indoor heat exchanger is generated according to the t6 and the t9; when the current working condition of the air conditioner is a heating working condition, according to the t1, the t2, the t5, and the t7, refrigerant enthalpy values and lubricating oil enthalpy values of an air return opening, an exhaust opening, the second end of the indoor heat exchanger and the first end of the indoor heat exchanger are generated respectively, and mixture enthalpy values h1, h2, h5 and h7 of the temperature detection points are further generated; according to the power of the compressor, the h1, the h2, the h5 and the h7, heating capacity of the air conditioner is generated; and the energy efficiency of the air conditioner is generated according to the power consumption power and the heating capacity of the air conditioner.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an energy efficiency calculation method for 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. 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 ...
