China's commercial freezer market is significantly different from the household freezer market in terms of channels and products. The commercial freezer market mainly consists of the industry's large customer market and the end of the fragmented customer market, in which the freezer manufacturers are mainly in the way of direct sales to cover the industry's customer market, and every year through the beverage, ice cream industry, large customers of the bidding to determine the intention of commercial freezer purchases, and in the fragmented customer market mainly rely on the dealers to cover.
Development
Commercial freezers are the product of the market economy, with the development and growth of major beverage, ice cream, frozen food manufacturers expanding the market size, the product form a gradual breakdown. Initially, the market generally use the insulation box to maintain the temperature of the items, and later with the emergence of cold cabinets, the use of ordinary foam door cooler storage of beverages, ice for supermarkets, street stalls and other sales, the rapid development of FMCG products has led to the development of commercial freezers listed on the market, due to the display of a more intuitive, more professional storage temperature, and the use of a more convenient, commercial freezers rapidly expanding the size of the market.
The use of crowd
Convenience store owners, cold drink store vendors, supermarket salesmen, Internet café operators, hotel kitchens, theaters and so on.
Working Principle
And the same principle used in ordinary freezers, commercial freezers is to use the compressor to compress the liquid refrigerant into high-temperature and high-pressure gaseous refrigerant, and then sent to the condenser to dissipate the heat to become a low-temperature and high-pressure liquid refrigerant, so the condenser blowing out of the hot air. Then to the throttling device (generally use capillary tube) throttling pressure, into the evaporator, because the refrigerant from the capillary tube to reach the evaporator after the sudden increase in space, the pressure decreases, the liquid refrigerant will be vaporized into a gaseous low-temperature refrigerant, which absorbs a large amount of heat, the evaporator will become cooler, the use of direct cooling or air-cooled, to achieve the cabinet cooling.
Edit this section of the use of attention
1. Domestic freezers use AC 220V/50Hz power supply. If the power conditions do not meet the AC 220V/50Hz (187-242V), you must add more than 1,000W of automatic voltage regulator with the use.
2. Must use independent special socket and reliable grounding. The power cord of the freezer is equipped with a (grounding) plug that meets the standard three-wire (grounding) socket. Under no circumstances should the third (grounding) prong of the power cord be cut or removed.
3. It is strictly prohibited to put flammable, explosive dangerous goods and strong corrosive acid, alkali, etc. in the freezer.
4. Do not use combustible sprays close to the cooler to avoid fire.
5. When there is gas and other flammable gas leakage: close the valve of gas leakage; open the exhaust device, doors and windows; do not pull or plug the power plug of the freezer;
6. The key should be kept properly, do not let children play in the cabinet to prevent accidents.
7. Once the freezer cut off the power supply, need to wait more than five minutes before reconnecting, so as to avoid damage to the compressor or system. Maintenance, must be unplugged. After the freezer is installed in place, the plug should be accessible to prevent the occurrence of danger in time to unplug the power supply.
8. If the power cord needs to be lengthened, the cross-sectional area of the lengthened cord shall not be less than 0.75mm2. If the power cord is damaged, a special cord must be used, and the local after-sales service personnel of the freezer company should be contacted for replacement.
9. Just turn on the power of the freezer do not immediately into the food, let the empty cabinet run for a period of time (about 3 hours in summer, about 2 hours in winter), and then the frozen food loaded into the cabinet storage.
10. After the freezer is moved, it should be left to stand for more than ten minutes before turning on the power.
11. Regularly clean the freezer, in order to safe cleaning before the power plug removed. Regular dusting of the heat exchanger in the cabin can enhance the efficiency of heat transfer and reduce energy consumption.
12. Mechanical defrosting of commercial freezers should be regularly defrosted to avoid the frost layer is too thick to increase the energy consumption of the freezer. Defrosting, the first cabinet goods transfer, leave a period of time until the frost layer melted and then use the freezer equipped with a defrost shovel shovel, avoid using sharp objects brute force defrosting, so as not to damage the inner wall of the freezer.
Product classification
Commercial freezers are generally divided into commercial refrigerated cabinets (also known as beverage cabinets), commercial refrigerated cabinets (also known as cold food cabinets), kitchen refrigerators of three major categories, the volume from 20L to 1600L ranging.

Kitchen refrigerators, also known as kitchen freezers, are low-temperature storage devices used in the restaurant industry for storing ingredients. Because the kitchen refrigerator is used in the environment for the kitchen, and to contact with food and raw materials, it should be wear-resistant, acid and alkali resistance, fire prevention, anti-bacteria, hygiene and other characteristics, so the kitchen refrigerator is generally stainless steel. Kitchen refrigerator according to the structure and the door body is generally divided into desktop, two-door, four-door, six-door, etc. Kitchen refrigerator door increase, said the box separated into different temperature ranges of the number of space increases, so that the kitchen refrigerator function more perfect, different storage temperature requirements of the goods can be accessed separately in different doors, can reduce the storage of goods interfere with each other, at the same time is conducive to reducing the cold air leakage. Haier kitchen refrigerator as a newcomer to the industry, backed by Haier's strong technical reserves, advanced experimental testing equipment, professional production process, has now entered the military supply channel.
