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 thereof comprises following steps: the current station of the air conditioner, the power of a compressor and the air conditioner power consumption are obtained; the temperature t1 of an air returning opening, the temperature t2 of an exhaust opening, the temperature t4 of the first end of an outdoor heat exchanger and the temperature t6 of the middle of an indoor heat exchanger in the compressor, and the indoor environment temperature t9 are obtained; according to t6 and t9, the temperature t7 of the first end of the indoor heat exchanger is generated; when the current station of the air conditioner is the refrigeration station, according to t1, t2, t4 and t7, the refrigerant enthalpy values and lubricating oil enthalpy values of the air returning opening, the exhaust opening, the first end of the outdoor heat exchanger and the first end of the indoor heat exchanger are correspondingly generated; according to the refrigerant enthalpy values and the lubricating oil enthalpy values of the temperature detection points, mixture enthalpy values h1, h2, h4 and h7 of the temperature detection points are correspondingly generated; according to the power of the compressor, h1, h2, h4 and h7, the refrigeration amount of the air conditioner is generated; according to power consumption and the refrigeration amount of the air conditioner, the energy efficiency of the air conditioner is generated.

Description

Technical field [0001] The present 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-temporary computer-readable storage medium. Background technique [0002] Whether the air conditioner is energy-efficient 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. To this end, an object of the present invention is to provide an energy efficiency calculation method for an air conditioner, which can accurately detect the energy efficiency of the air conditioner in real time...
