Abstract

The invention discloses an air conditioner and an energy efficiency calculation method and system thereof, and the method comprises the following steps: obtaining the current working condition of the air conditioner, the power of a compressor, the power consumption of the air conditioner and the heat dissipating capacity Qloss of a shell of the compressor, and obtaining the pressure of the high-pressure side of an exhaust port of the compressor; the temperature t1 of an air return opening of the compressor, the temperature t2 of an exhaust opening of the compressor, the temperature t4 of the first end of an outdoor heat exchanger, the temperature t7 of the first end of an indoor heat exchanger and the air supply temperature t8 of the compressor are obtained; when the current working condition of the air conditioner is the refrigeration working condition, the mixture enthalpy values h1, h2, h4, h7, h8'and h8 ''of all the temperature detection points are generated according to t1, t2, the high-pressure side pressure, t4, t7 and t8, the refrigerating capacity of the air conditioner is generated according to the power of the compressor, Qloss, h1, h2, h4, h7, h8' and h8 '', and the energy efficiency of the air conditioner is generated according to the power consumption of the air conditioner and the refrigerating capacity.

Description

[0001] This application is a division with the application date of "August 31, 2017", the application number of "201710774267.X", and the application name of "air conditioner and its energy efficiency calculation method and system" technical field [0002] The present invention relates to the technical field of air conditioners, and in particular, to an energy efficiency calculation method of an air conditioner, an air conditioner, a non-transitory computer-readable storage medium, and an energy efficiency calculation system of an air conditioner. Background technique [0003] Whether the air conditioner is energy-saving and comfortable is a problem that users are more concerned about. [0004] Since the current air conditioner cannot know the change of energy efficiency during operation, it is difficult to maintain a better operating state, and the cooling and heating effect and energy saving performance are not ideal. SUMMARY OF THE INVENTION [0005] The present inventi...
