Abstract

The invention discloses an air conditioner and an energy efficiency calculating method of the air conditioner. The energy efficiency calculating method comprises the following steps that the current working condition of the air conditioner, the power of a compressor and shell heat dissipation capacity Qloss are obtained; the temperature t1 of an air return port in the compressor, the temperature t2 of the air outlet in 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 supplementing temperature t8 of the compressor are obtained; when the current working condition is the refrigeration working condition, the mixture enthalpy value h1 of the air return port, the mixture enthalpy value h2 of the air outlet, the mixture enthalpy value h4 of the first end of the outdoor heat exchanger, the mixture enthalpy value h7 of the first end of the indoor heat exchanger, the enthalpy value h8' of the mixture supplemented into the compressor and the mixture enthalpy value h8'' of a flash vessel are correspondingly generated according to t1, t2, t4, t7 and t8, the power of the compressor is obtained according to the current frequency of the compressor and a preset compressor performance curve, the refrigeration capacity of the air conditioner is generated according to power, Qloss, h1, h2, h4, h7, h8' and h8'', and the energy efficiency of the air conditioner is generated according to the power consumption and refrigeration capacity 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 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, 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 cond...
