The invention provides an air conditioner and an energy efficiency calculating method therefor. The method comprises the steps of acquiring a current working condition and the power consumption of an conditioner, and the power, the shell heat dissipation quantity Qloss and the high-pressure side pressure of an exhaust port of a compressor; acquiring the air return port temperature t1 of an air return port of the compressor, the exhaust port temperature t2 of the exhaust port of the compressor, the first end temperature t4 of a first end of an outdoor heat exchanger, and the first end temperature t7 of a first end of an indoor heat exchanger; if the current working condition of the air conditioner is a refrigerating working condition, generating the refrigerant enthalpy value h1 of the air return port, the refrigerant enthalpy value h2 of the exhaust port, the refrigerant enthalpy value h4 of the first end of the outdoor heat exchanger, and the refrigerant enthalpy value h7 of the first end of the indoor heat exchanger according to t1, t2, the high-pressure side pressure, t4, and t7; generating a refrigeration quantity of the air conditioner according to the power, Qloss, h1, h2, h4 and h7; generating the energy efficiency of the air conditioner according to the power consumption and the refrigeration quantity. Thus, the energy efficiency of an air conditioner can be detected accurately in real time.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner energy efficiency calculation method and an air conditioner. Background technique [0002] As the country pays more and more attention to energy saving, consumers have higher and higher requirements for energy saving and comfort of air conditioners. At present, during the operation of the air conditioner, since it is impossible to detect the change of the energy efficiency of the air conditioner in real time, it is difficult for the air conditioner to maintain a good operating state, resulting in unsatisfactory cooling, heating effects and energy-saving performance. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. [0004] Therefore, the first object of the present invention is to provide an energy efficiency calculation method of an...
