[0015] 1. This utility model utilizes a carbon dioxide direct expansion refrigeration unit. When storing items to be refrigerated, it sends a signal to the power supply unit when refrigeration is needed. This causes the drive module to control the insulated glass door to move and close on the side of the adjustment track. The mounting base supports the drive module. When the insulated glass door moves to the closed position, the refrigeration unit receives the signal and injects refrigeration into the internal cavities of the insulated glass door at both ends through the condensing pipe, forming a central condensing space. This causes the internal temperature to drop rapidly, preventing poor insulation of the insulated glass door from causing its protective function to fail.

The temperature monitor can be set to a temperature value and a signal is sent when the limit is reached. The limit plate protects the insulated glass door when it is reset. Two insulated glass doors are used for front and rear protection to enhance its heat preservation performance. Attached Figure Description
