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 that the current working condition and power consumption of the air conditioner, the current frequency of a compressor and the shell heat dissipating capacity Qloss are obtained; the temperature t1 of an air return opening of the compressor, the temperature t2 of an exhaust opening, 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 is the refrigeration working condition, a mixture enthalpy value h1 of an air return port, a mixture enthalpy value h2 of an exhaust port, a mixture enthalpy value h4 of the first end of an outdoor heat exchanger, a mixture enthalpy value h7 of the first end of an indoor heat exchanger, an enthalpy value h8'of a mixture supplemented into a compressor and a mixture enthalpy value h8 ''of a flash evaporator are generated according to t1, t2, t4, t7 and t8; obtaining the power of the compressor according to the current frequency of the compressor and a preset compressor performance curve; the refrigerating capacity of the air conditioner is generated according to the power, Qloss, h1, h2, h4, h7, h8'and h8 '', and the energy efficiency of the air conditioner is generated according to the air conditioner power consumption and the refrigerating capacity.

Description

[0001] This case is a divisional application of the Chinese patent application number 201710775493.X, the filing date is 2017-08-31, and the invention name is "air conditioner and its energy efficiency calculation method". technical field [0002] 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 [0003] Whether the air conditioner is energy-saving and comfortable is a problem that users are more concerned about. [0004] 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 [0005] The present invention aims to solve one of the technical problems in the above-mentioned technologies a...
