Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a horizontal dual-temperature refrigerator with an adjustable inner cavity size. Background Art

[0002] A freezer, also called a refrigerator, is a device that preserves food and other items at low temperatures. There are two types of freezers: home and commercial. Commercial freezers are used in restaurants, water bars, food processing, and supermarkets. The basic function of a freezer is to refrigerate and keep the inside of the box at an appropriate low temperature. The refrigeration system generally consists of four basic components: a compressor, a condenser, a capillary tube or a thermal expansion valve, and an evaporator. Refrigerant is a liquid that can boil at low temperatures under low pressure and absorbs heat when boiling. The refrigerant circulates continuously in the refrigeration system. The compressor increases the gas pressure of the refrigerant, creating liquefaction conditions. When passing through the condenser, it condenses and liquefies to release heat, then reduces the pressure and temperature when passing through the capillary tube, and then absorbs heat through the evaporator or coil heat exchange.

[0003] The current horizontal dual-temperature freezer generally adopts two inner chambers, and the two inner chambers are separated by a fixed partition. If the amount of refrigerated food and frozen food changes, the fixed-sized refrigeration chamber and freezing chamber are sometimes difficult to adapt to the corresponding amount of food or goods. Therefore, an improved technology is urgently needed to solve this problem in the prior art. Utility Model Content
