1. A device for controlling a low-temperature refrigeration air valve, comprising:
a first acquiring module, configured to acquire a current environment temperature;
a determining module, configured to determine an initial target pressure of a current system and an initial opening degree of the air valve according to the current environment temperature;
a second acquiring module, configured to acquire an actual pressure of the current system and a target pressure of the current system; and
an adjusting module, configured to adjust 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,
wherein the determining module is further configured to determine an adjustment extent of the opening degree of the air valve based on the initial target pressure of the current system and the initial opening degree of the air valve,
wherein the first acquiring module is configured to acquire the current environment temperature at intervals of a preset time period,
the determining module is configured to adjust the target pressure of the current system according to the current environment temperature, and
the second acquiring module is configured to acquire an adjusted target pressure of the current system.
