Air conditioner and energy efficiency calculating method and system thereof

Abstract

The invention discloses an air conditioner and an energy efficiency calculating method and a system thereof. The method comprises the following steps: present working conditions of the air conditioner, the power of a compressor, the power consumption of the air conditioner and a shell heat dissipating quantity Qloss of the compressor are obtained; a high-pressure side pressure of an exhaust port of the compressor is obtained; a temperature t1 of an air return port in the compressor, a temperature t2 of the exhaust port in the compressor, a temperature t4 of a first end of an outdoor heat exchanger, a temperature t7 of a first end of an indoor heat exchanger and an air supply temperature t8 of the compressor are obtained; when the present working conditions of the air conditioner are refrigeration working conditions, mixture enthalpy values h1, h2, h4, h7, h8' and h8'' of all temperature detecting points are respectively generated according to t1, t2, the high-pressure side pressure, t4, t7 and t8; the refrigeration capacity of the air conditioner is generated according to the power of the compressor, the Qloss, h1, h2, h4, h7, h8' and h8''; and the energy efficiency of the air conditioner is generated according to the power consumption and the 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, a non-temporary computer readable storage medium and an energy efficiency calculation system of an air conditioner. Background technique [0002] Whether the air conditioner is energy-saving and comfortable is a question that users are more concerned about. [0003] The current air conditioner cannot know the change of energy efficiency during operation, so 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 [0004] The present invention aims to solve one of the technical problems in the above technology at least to a certain extent. For this reason, the first objective of the present invention is to propose an air conditioner energy efficiency calculation method, which can accurately detec...
