Air conditioner and energy efficiency calculating method thereof

Abstract

The invention discloses an air conditioner and an energy efficiency calculating method thereof. The method comprises the following steps of: acquiring the current working condition of the air conditioner, the power of a compressor and the power consumption of the air conditioner; acquiring the pressure of a low pressure side; acquiring the temperature t1 of an air return port of the compressor, the temperature t2 of an exhaust port of the compressor, the pressure of the low pressure side, the first end temperature t4 of an outdoor heat exchanger, the first end temperature t7 of an indoor heat exchanger and the air supplementing temperature t8 of the compressor; when the current working condition of the air conditioner is a refrigerating working condition, separately generating a refrigerant enthalpy value h1 of the air return port, a refrigerant enthalpy value h2 of the exhaust port, a refrigerant enthalpy value h4 at the firs end of the outdoor heat exchanger, a refrigerant enthalpy value h7 of the first end of the indoor heat exchanger, a gaseous enthalpy value h8' of a refrigerant supplemented to the compressor and a liquid refrigerant enthalpy value h8'' of a flash evaporator; generating a refrigerating capacity of the air conditioner according to the power of the compressor and h1, h2, h4, h7, h8' and h8''; and generating the energy efficiency of the air conditioner according to the power consumption and the refrigerating capacity of the air conditioner. The energy efficiency of the air conditioner can be accurately detected.

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 air conditioner in the related art cannot know the change of 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 co...
