Abstract

The invention is suitable for the technical field of air conditioners, and provides an evaporator state detection method and device, air conditioning equipment and a storage medium. The refrigerant pressure of an evaporator outlet is detected; then the saturation temperature of an evaporator is obtained according to the refrigerant pressure; and finally, the freezing state of the evaporator is determined according to the saturation temperature, the accurate saturation temperature of the evaporator can be obtained according to the refrigerant pressure data, obtained through direct measurement, of the evaporator outlet, and therefore the freezing state of the evaporator can be accurately judged according to the saturation temperature. And the operation state of the air conditioning equipment is adaptively controlled according to the freezing state of the evaporator so as to protect the evaporator and a compressor and prevent the evaporator and the compressor from continuous low-pressure operation.

Description

technical field [0001] The present application belongs to the technical field of air conditioning, and in particular relates to an evaporator state detection method and device, air conditioning equipment and a storage medium. Background technique [0002] With the continuous development of air-conditioning technology and the promotion of the application of air-conditioning systems, air-conditioning systems are more and more widely used in people's daily production and work life, and people pay more and more attention to the safety requirements of air-conditioning systems, including evaporators Identification of frozen state. The evaporator uses the liquid low-temperature refrigerant to evaporate easily under low pressure, transform into vapor and absorb the heat of the cooled medium to achieve the purpose of refrigeration. It is an indispensable and important part of air-conditioning equipment. [0003] At present, most air-conditioning systems use the temperature of the ev...
