Problems solved by technology
[0004] However, if you do not have the laboratory test conditions for enthalpy difference, you will not be able to directly use the above two methods to test the capacity and energy efficiency of air conditioners.
Moreover, the refrigerant flow value in the air conditioner is a relatively independent parameter relative to temperature and pressure, and cannot be obtained by temperature point fitting. If the flow sensor is directly installed to measure the refrigerant flow value, the cost will be high, and The flow sensor is bulky and difficult to implement on the product

Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for calculating the capacity and energy efficiency of an air conditioner, a computer storage medium and an air conditioner. Background technique [0002] For the test of air conditioner capacity and energy efficiency, it is usually carried out in the enthalpy difference laboratory. In the enthalpy difference laboratory, the power consumption of the air conditioner can be directly obtained by using the power meter connected to the air conditioner. In the enthalpy difference laboratory, the air-side enthalpy difference method and the refrigerant-side enthalpy difference method are usually used to test the ability of the air conditioner. The air-side enthalpy difference method uses the air volume chamber to test the dry and wet bulb temperature of the air entering and leaving the indoor unit. The air enthalpy difference is multiplied by the air volume to calculate ...
