Air conditioner and energy efficiency calculation method thereof

Abstract

The invention discloses an air conditioner and an energy efficiency calculation method thereof. The energy efficiency calculation method comprises the following steps that the current working condition of the air conditioner, the power of a compressor and the power consumption of the air conditioner are obtained; the shell heat dissipating capacity Qloss of the compressor is obtained; the temperatures t2, t4 and t6 of an air outlet in the compressor, a first end of an outdoor heat exchanger and the middle portion of an indoor heat exchanger, and the indoor ambient temperature t9 are obtained; the return air inlet temperature t1 of a return air inlet in the compressor is generated according to the t9 and the t4, and the temperature t7 of a first end of the indoor heat exchanger is generated according to the t9 and the t6; when the current working condition of the air conditioner is a refrigerating working condition, the refrigerant enthalpy value h1 of the return air inlet, the refrigerant enthalpy value h2 of the air outlet, the refrigerant enthalpy value h4 of the first end of the outdoor heat exchanger and the refrigerant enthalpy value h7 of the first end of the indoor heat exchanger are generated according to the t1, t2, t4 and t7 correspondingly; the refrigerating capacity of the air conditioner is generated according to the power of the compressor, the Qloss, the h1, the h2, the h4 and the h7; and the energy efficiency of the air conditioner is generated according to the power consumption and the refrigerating 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, 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 conditioner...
