Embodiment Construction

[0035] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0036] The main solution of the embodiment of the present invention is:

[0037] Obtain the temperature of the electronic control module in the refrigeration device regularly;

[0038] Obtain the dew point temperature corresponding to the outdoor environment of the refrigeration device;

[0039] When the temperature of the electronic control module is lower than the dew point temperature, the opening degree of the electronic expansion valve in the refrigeration device is reduced to increase the return air temperature of the liquid storage tank.

[0040] In the prior art, the cooling medium is generally used to dissipate heat. However, the temperature of the cooling medium is often low, resulting in low surface temperature of the electronic control unit and condensation.

[0041] The present invention provides a solution to...

Abstract

The invention discloses a control method of a refrigeration device, comprising the following steps of: acquiring the temperature of an electric control module in the refrigeration device; acquiring the temperature of a dew point corresponding to the outdoor environment of the refrigeration device; when the temperature of the electronic control module is lower than the temperature of the dew point,the opening degree of an electronic expansion valve in the refrigeration device is appropriately reduced to improve the return air temperature of a liquid storage tank. The invention further discloses a refrigeration device and a computer readable storage medium. In the invention, the electric control module is radiated through the liquid storage tank, and when the temperature of the electric control module is lower than the temperature of dew point in the outdoor environment, the opening degree of the expansion valve in the refrigeration system is appropriately reduced, so that the return air temperature of the liquid storage tank is improved, the temperature of the liquid storage tank can be improved by increasing the return air temperature, the temperature of the electric control module is further improved, and condensation of the electric control module is avoided.

Description

Technical field [0001] The present invention relates to the technical field of refrigeration devices, in particular to a refrigeration device control method, device and computer-readable storage medium. Background technique [0002] Air conditioners, refrigerators and other devices require the participation of compressor components in order to realize the refrigerant circulation. The main components of the compressor components include the compressor and the liquid storage tank. In order to realize the control of the compressor, such as starting, stopping and adjusting the operating frequency, the refrigeration device also needs to include an electronic control module unit. When the electronic control module unit controls the compressor, a certain amount of power is generated. Part of this power is converted into heat. The heat needs to be dissipated in time to ensure that the electronic control unit is in a reasonable temperature range. [0003] The existing electronic control un...
