Abstract

The invention discloses an air conditioner and an energy efficiency computing method thereof. The energy efficiency computing method comprises the following steps of acquiring a current working condition of the air conditioner, power of a compressor and power consumption of the air conditioner; acquiring shell heat dissipating capacity Qloss of the compressor; acquiring temperatures t2, t4, t5, t6 and t10 of detecting points; generating temperatures t1, t7 and t8 according to the corresponding temperatures; when the current working condition of the air conditioner is a refrigeration condition, generating corresponding refrigerant enthalpy values and lubricating oil enthalpy values according to the temperatures of the corresponding points; generating a mixture enthalpy value of the corresponding point according to the refrigerant enthalpy value and the lubricating oil enthalpy value of each point; generating the refrigerating capacity of the air conditioner according to the power of the compressor, the shell heat dissipating capacity Qloss of the compressor and each mixture enthalpy value; generating the energy efficiency of the air conditioner according to the power consumption and the refrigerating capacity of the air conditioner. The energy efficiency computing method is capable of accurately detecting the energy efficiency of the air conditioner in real time and improving the operating state.

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 ...
