Abstract

The invention discloses an air conditioner and a method for computing energy efficiency thereof. The method for computing the energy efficiency includes steps of acquiring current working conditions of the air conditioner, power of a compressor and power consumption of the air conditioner; acquiring heat dissipating capacity Q<loss> of a shell of the compressor; acquiring the temperatures t1, t2, t4, t7, t8 and t11 of various detection points; generating enthalpy values h1, h2, h4, h7, h8 and h11 of refrigerants of the corresponding detection points according to the corresponding temperatures when the current working conditions of the air conditioner are refrigeration conditions; generating refrigerating capacity of the air conditioner according to the power of the compressor, the heat dissipating capacity Q<loss> of the shell of the compressor and the corresponding enthalpy values H1, h2, h4, h7, h8 and h11 of the refrigerants of the various detection points; generating the energy efficiency of the air conditioner according to the power consumption of the air conditioner and the refrigerating capacity. The air conditioner and the method have the advantages that the energy efficiency of the air conditioner can be accurately detected in real time, and accordingly running states can be optimized.

Description

technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to an energy efficiency calculation method of an air conditioner and the air conditioner. Background technique [0002] With more and more emphasis on energy saving, whether the air conditioner is energy-saving and comfortable has attracted more and more attention from users. [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 embodiment of the present invention proposes an energy efficiency calculation method of an air conditioner, which can accurately detect the energy efficiency of the air ...
