Air conditioner and energy efficiency calculating method thereof

Abstract

The invention discloses an air conditioner and an energy efficiency calculating method and system thereof. The energy efficiency calculating method includes the following steps that the current working condition and the electricity consumption power of the air conditioner and compressor power are obtained; the high-pressure-side pressure corresponding to an exhaust port of the compressor, the exhaust port temperature t2, the low-pressure-side pressure corresponding to an air return port, the air return port temperature t1, the outdoor heat exchanger first end temperature t4 of the outdoor heat exchanger first end and the indoor heat exchanger first end temperature t7 of the indoor heat exchanger first end are obtained; when the current working condition of the air conditioner is the refrigeration condition, 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 outdoor heat exchanger first end and the refrigerant enthalpy value h7 of the indoor heat exchanger first end are generated according to t1, t2, the high-pressure-side pressure, the low-pressure-side pressure, t4 and t7 respectively; the refrigerating capacity of the air conditioner is generated according to the power, h1, h2, h4 and h7; the energy efficiency of the air conditioner is generated according to the air conditioner electricity consumption power and the refrigerating capacity, so that the energy efficiency of the air conditioner is 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...
