Commercial freezer cabinet temperature is generally below -15 degrees, mainly for ice cream, frozen dumplings, dumplings, frozen meat storage sales. According to the structure of the form and industry habits are divided into horizontal ice cream cabinet, island frozen food cabinet, vertical commercial freezer cabinet, desktop cabinet, playing cabinet. Horizontal ice cream cabinet for the Chinese market for the mainstream of commercial freezers, common volume from 100L to 600L ranging.

Vertical commercial freezers are mainly used for high-end ice cream storage and sales due to their larger display area and more intuitive display effect. Countertop cabinets are generally used for counter sales in high-end places.

The refrigerator refrigeration system, the main components of the compressor, condenser, evaporator and capillary tube four parts, since a closed loop system. The evaporator is installed on the top of the inside of the refrigerator, and the other parts are installed on the back of the refrigerator. The system is charged with a substance called "Freon 12 (CF2Cl2, international symbol R12)" as a refrigerant.

Freon 12 vaporizes from a low-pressure liquid to a gas in the evaporator, absorbing heat from the refrigerator and lowering the temperature inside. The gaseous Freon 12 is sucked in by the compressor, which compresses it into a high-temperature, high-pressure gas and then discharges it into the condenser. In the condenser, the gaseous Freon 12 is continuously exothermic to the surrounding space and gradually liquefies into a liquid.

These high-pressure liquid must flow through the capillary tube, throttling down the pressure to slowly flow into the evaporator, to maintain the evaporator continues to vaporize, heat absorption and cooling. In this way, the refrigerator using electrical energy to do work, with the refrigerant state of matter changes, the box evaporator around the heat transfer to the box after the condenser to release, so that week after week and constantly cycle, in order to achieve the purpose of refrigeration.
