Abstract

The invention discloses an air conditioner and an energy efficiency calculation method thereof. The energy efficiency calculation method comprises the steps that the current working condition of the air conditioner, power of a compressor and air conditioner power consumption are obtained; temperatures t2, t4, t5, t6 and t10 of an exhaust port of the compressor, the first end of an outdoor heat exchanger, the second end of an indoor heat exchanger, the middle of the indoor heat exchanger and the interior are obtained respectively; the temperature t1 of a return air inlet of the compressor, the temperature t7 of the first end of the indoor heat exchanger and the air supply temperature t8 are generated separately; when the current working condition of the air conditioner is the refrigeration condition, refrigerant enthalpy values h1, h7, h2, h4, h8' and h8'' corresponding to all points are generated respectively according to corresponding point temperatures; the refrigerating capacity of the air conditioner is generated according to the power of the compressor and all the enthalpy values; 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.

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 ...
