Abstract

The invention discloses an air conditioner and an energy efficiency calculating method thereof. The method comprises the following steps: present working conditions of the air conditioner, the power of a compressor and the power consumption of the air conditioner are obtained; a high-pressure side pressure of an exhaust port of the compressor, a temperature t1 of an air return port in the compressor, a temperature t2 of the exhaust port in the compressor, a temperature t4 of a first end of an outdoor heat exchanger and a temperature t7 of a first end of an indoor heat exchanger are obtained; when the present working conditions of the air conditioner are refrigeration working conditions, a refrigerant enthalpy value h1 of the air return port, a refrigerant enthalpy value h2 of the exhaust port, a refrigerant enthalpy value h4 of the first end of the outdoor heat exchanger and a refrigerant enthalpy value h7 of the first end of the indoor heat exchanger are respectively generated according to t1, t2, the high-pressure side pressure, t4 and t7; the refrigeration capacity of the air conditioner is generated according to the power of the compressor, h1, h2, h4 and h7; and the energy efficiency of the air conditioner is generated according to the power consumption and the refrigeration capacity of the air conditioner, so that the real-time accurate detection of the energy efficiency of the air conditioner in realized.

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...
