The following description is given to enable any person skilled in the art to implement and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0080] First, the terms involved in this application are explained:

[0081] Air Conditioner: Generally, it includes cold source / heat source equipment, cold and hot medium distribution system, terminal device and other auxiliary equipment. It mainly includes refrigeration host, water pump, fan and pipeline system. The terminal device is responsible for using the cold and hot water distributed to process the air state so that the air parameters of the target environment meet certain requirements.

[0082] Refrigerant: A working fluid used in air conditioning systems that transfers heat and refrigerates air in the air conditioning cycle. Common air conditioning refrigerants include Freon series, ammonia, carbon dioxide, etc. Refrigerant leakage refers to the leakage of refrigerant in the air conditioning system at some place, causing the refrigerant to escape from the system. Refrigerant leakage may have some negative impacts on the environment and human health, and also affect the performance and efficiency of the air conditioning system.

[0083] Superheat: Superheat refers to the difference between the steam temperature at the evaporator outlet and the saturation temperature in an air conditioning or refrigeration system. It is an important parameter used to evaluate the operating status and performance of the air conditioning system. The calculation method of superheat can be determined by measuring the difference between the steam temperature at the evaporator outlet and the saturation temperature. The saturation temperature refers to the temperature at which liquid and gas exist at the same time at a given pressure. The value of superheat can be obtained by looking up the steam table or using a temperature sensor and a pressure sensor.

[0084] The embodiments of the present application provide an air conditioning control method, device, electronic device, and computer-readable storage medium.

[0086] However, in the existing air-conditioning control technology, the most intuitive manifestation of air-conditioning refrigerant leakage is the increase in exhaust temperature. Therefore, when judging the air-conditioning refrigerant leakage, the judgment is only made based on the exhaust temperature value, resulting in inaccurate judgment results. It is impossible to detect whether the air-conditioning refrigerant is leaking in time, which affects the air-conditioning operation efficiency and brings safety hazards to users.

[0087] The embodiment of the present application provides an air conditioning control method, device, electronic device and computer-readable storage medium.

[0088] In summary, the air-conditioning control method provided in the embodiment of the present application can judge the air-conditioning refrigerant leakage according to the air-conditioning exhaust pressure, exhaust temperature and compressor frequency, and adjust the corresponding operation strategy, thereby achieving the technical effect of improving the accuracy of refrigerant leakage judgment, timely changing the air-conditioning operation strategy, and improving the user experience.
