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, power of a compressor and air conditioner power consumption are obtained; the temperatures t1, t2, t4, t7, t8 ad t11 of all detection points are obtained; when the current working condition of the air conditioner is the refrigeration condition, refrigerant enthalpy values and lubricating oil enthalpy values of all detection points are generated according to the temperatures corresponding to all the detection points respectively; mixture enthalpy values h1, h2, h4, h7, h8 and h11 corresponding to all the detection points are generated according to the refrigerant enthalpy values and the lubricating oil enthalpy values of the corresponding detection points; the refrigerating capacity of the air conditioner is generated according to the power of the compressor and the mixture enthalpy values h1, h2, h4, h8, h11 and h7 of all the detection points; the energy efficiency of the air conditioner is generated according to the air conditioner power consumption and the refrigerating capacity. The energy efficiency of the air conditioner can be detected accurately in real time, and operating condition 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 ...
