Title:
METHOD AND DEVICE FOR CONTROLLING LOW-TEMPERATURE REFRIGERATION AIR VALVE
Document Type and Number:
WIPO Patent Application WO/2020/133927
Kind Code:
A1
Abstract:
Provided in the present invention are a method and a device for controlling a low-temperature refrigeration air valve, wherein the method comprises: acquiring a current environment temperature; according to the current environment temperature, determining an initial target pressure of the current system and an initial opening degree of an air valve; acquiring an actual pressure of the current system and the current system target pressure; and adjusting the opening degree of the air valve according to a difference value between the current system target pressure and the current system actual pressure, wherein the air valve is arranged on a low temperature cover. Therefore, according to the low-temperature refrigeration air valve control method provided in the embodiment of the present invention, the opening degree of the air valve is adjusted according to the difference value between the current system target pressure and the actual pressure of the current system, so as to meet the refrigeration needs of a user in an ultra-low temperature environment, and expand the scope of refrigeration operations.
