Air conditioner and energy efficiency calculating method thereof

Abstract

The invention discloses an air conditioner and an energy efficiency calculating method thereof. The energy efficiency calculating method includes the following steps that the current working condition, the compressor power and air conditioner electricity consumption power of the air conditioner are obtained; the air return port temperature t1 of an compressor, the exhaust port temperature t2 of the compressor, the outdoor heat exchanger first end temperature t4, the indoor heat exchanger first end temperature t7 and the air supplementing temperature t8 of the compressor are obtained; when the current working condition of the air conditioner is the refrigeration condition, the refrigerant enthalpy value h1 of an air return port, the refrigerant enthalpy value h2 of an exhaust port, the refrigerant enthalpy value h4 of the outdoor heat exchanger first end, the refrigerant enthalpy value h7 of the indoor heat exchanger first end, the enthalpy value h8' of the gaseous refrigerant supplemented into the compressor and the liquid refrigerant enthalpy value h8'' of a flash evaporator are generated according to t1, t2, t4, t7 and t8 respectively; the refrigerating capacity is generated according to the compressor power, h1, h2, h4, h7, h8' and h8''; the energy efficiency of the air conditioner is generated according to the air conditioner electricity consumption power and the refrigerating capacity. By means of the energy efficiency calculating method, the energy efficiency of the air conditioner can be accurately detected in real time.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an energy efficiency calculation method for 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, an 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 condition...
