A control method, device, equipment and readable storage medium of a refrigeration system

Abstract

The present application discloses a control method of a refrigeration system, including obtaining the temperature outside the vehicle at the current moment; calculating the first difference between the temperature at the previous moment and the temperature at the current moment, and judging whether the first difference exceeds the first preset temperature threshold; if yes, control the refrigeration system to output the first cooling capacity, wherein the first cooling capacity is smaller than the second cooling capacity at the previous moment. In this application, by collecting the ambient temperature outside the vehicle and judging its change trend, when it is found that the vehicle enters an area with a lower temperature, such as the vehicle enters a tunnel, rain or hail area, the output of the refrigeration system cooling capacity is reduced to prevent the evaporator Freezing will help prolong the life of the refrigeration system. The application also discloses a refrigeration system control device, equipment and a computer-readable storage medium, which have the same beneficial effect as the above-mentioned refrigeration system control method.

Description

technical field [0001] The present application relates to the technical field of automatic control, in particular to a control method, device, equipment and computer-readable storage medium of a refrigeration system. Background technique [0002] With the development of technology, refrigeration equipment has been installed on many vehicles, such as air conditioners on trains. When the temperature inside the train is too high, the temperature inside the train reaches the target temperature by turning on the cooling mode of the air conditioner. During this process, protective measures will not be taken due to changes in the operating environment of the train, such as the train entering a tunnel or entering a rain and hail area. [0003] However, due to the complex and changeable train operating environment, the operating route may pass through areas with large temperature and humidity changes such as sunny, rainy and hail areas, or tunnel areas. When the train enters from a...

Problems solved by technology

[0003] However, due to the complex and changeable operating environment of the train, the operating route may pass through areas with large temperature and humidity changes such as sunny days, rainy and hail areas, or tunnel areas

When the train enters from a high-temperature environment into a low-temperature area such as rain or hail, especially when the humidity also increases, due to the large drop in ambient temperature in a short period of time and the increase in humidity, if no protective measures are taken, it is easy to cause the train air conditioning The evaporator freezes, affecting the life of the air conditioner
