The invention discloses a new type of sideboard cabinet, comprising cabinet, support legs and drawer section; the bottom of the cabinet is fixed to the ground through the support legs, the cabinet is equipped with a plurality of storage spaces along its lengthwise direction, corresponding storage spaces of the cabinet are equipped with bi-parting cabinet doors, the storage spaces in the cabinet are provided with a plurality of groups of criss-crossed partition boards, and the multiple groups of partition boards divide the storage spaces into a plurality of groups of storage compartments; the drawer section is slidably arranged in the storage space located at one side of the cabinet.

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.
