Abstract

The invention discloses an air conditioner and an energy efficiency calculation method thereof. The energy efficiency calculation method comprises the following steps: current working condition of the air conditioner, power of a compressor and power consumption power of the air conditioner are acquired; temperature of each temperature point is acquired; the temperature t1, t7 and t8 are generated according to the corresponding temperatures of the temperature points; when the current working condition of the air conditioner is a refrigerating working condition, refrigerant enthalpy values and lubricating oil enthalpy values corresponding to the temperature points are generated according to the temperatures of the corresponding temperature points; h1, h2, h4, h7, h8' and h8'' are generated according to the refrigerant enthalpy values and the lubricating oil enthalpy values; refrigerating capacity of the air conditioner is generated according to the power of the compressor and the enthalpy value of each mixture; and the energy efficiency of the air conditioner is generated according to the power consumption power and the refrigerating capacity of the air conditioner so that the energy efficiency condition can be obtained in real time, and the operation state is optimized.

Description

technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to an energy efficiency calculation method of an air conditioner and the air conditioner. Background technique [0002] With more and more emphasis on energy saving, whether the air conditioner is energy-saving and comfortable has attracted more and more attention from users. [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 embodiment of the present invention proposes an energy efficiency calculation method of an air conditioner, which can accurately detect the energy efficiency of the air ...
