Abstract
Description

[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, bars, food processing, and supermarkets. The refrigeration system is generally composed 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 to create 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 boils and vaporizes to absorb heat when passing through the evaporator.
[0003] In the prior art, ice easily forms on one side of the refrigeration pipe inside the freezer, which not only causes food to stick to it, but also affects the refrigeration effect after freezing, causing food to spoil. Utility Model Content
