Abstract
A method and a device for controlling a low-temperature refrigeration air valve, the method includes: 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 a target pressure of the current system; and adjusting an opening degree of the air valve according to a difference value between the target pressure of the current system and the actual pressure of the current system, wherein the air valve is disposed at a low-temperature cover. An opening degree of the air valve is adjusted according to the difference value between the target pressure of the current system and the actual pressure of the current system, to meet the refrigeration demand of the user in an ultra-low temperature environment, expanding the operation scope of refrigeration.
