Air conditioner and energy efficiency calculating method thereof

Abstract

The invention discloses an air conditioner and an energy efficiency calculating method thereof. The energy efficiency calculating method thereof comprises following steps: the current station and the power consumption of the air conditioner, the power of a compressor, the high-pressure side pressure of an exhaust opening, exhaust opening temperature t2, the low-pressure side pressure of an air returning opening, the air returning opening temperature t1, the temperature t4 of the first end of an outdoor heat exchanger and the temperature t7 of the first end of an indoor heat exchanger are obtained; when the current station of the air conditioner is the refrigeration station, according to t1, t2, the high-pressure side pressure, the low-pressure side pressure, t4 and t7, the refrigerant enthalpy values and lubricating oil enthalpy values of the air returning opening, the exhaust opening, the first end of the outdoor heat exchanger and the first end of the indoor heat exchanger are correspondingly generated; according to the refrigerant enthalpy values and the lubricating oil enthalpy values, mixture enthalpy values h1, h2, h4 and h7 are generated; according to the power, h1, h2, h4 and h7, the refrigeration amount of the air conditioner is generated; according to power consumption and the refrigeration amount of the air conditioner, the energy efficiency of the air conditioner is generated, so that real-time accurate detection of energy efficiency of the air conditioner is achieved.

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...
