A refrigeration unit includes a compressor, an evaporator, a fan, and an air duct component, utilizing the evaporator for cooling and the fan to deliver cold air formed by heat exchange with the evaporator into compartments for cooling; a heating unit for transferring heat generated by the heating unit into the compartments for heating; a temperature sensor unit for detecting the actual temperature inside the compartments and the external environment temperature; and a control mainboard that selects cooling or heating based on the actual temperature within the compartments. When the control mainboard selects cooling by the refrigeration unit, the control mainboard obtains the actual environmental temperature, derives a corresponding correcting temperature difference according to the actual environmental temperature, and corrects the switch-on and switch-off temperatures of the compressor based on the corrected temperature difference; the compressor operates according to the switch-on and switch-off temperatures corrected by the corrected temperature difference.

Constant temperature wine cabinet

A constant temperature control method, an electronic device, and a constant temperature wine cabinet. The method includes obtaining a first temperature difference between the first actual temperature of the compartment and the baseline compartment temperature at a baseline environmental temperature; modifying the switch-on and switch-off temperatures of the compressor to obtain a first revised switch-on temperature and a first revised switch-off temperature based on the first temperature difference; obtaining a second temperature difference between the baseline compartment temperature and the second actual temperature of the compartment at an actual environmental temperature; modifying the first revised switch-on temperature and the first revised switch-off temperature to obtain a second revised switch-on temperature and a second revised switch-off temperature based on the second temperature difference; and controlling the compressor to switch on at the second revised switch-on temperature and switch off at the second revised switch-off temperature.
