Introducing all kinds of industrial refrigeration
Industrial cold storage above zero This type of industrial cold storage is designed to create temperatures above zero. In this way, if the temperature of the industrial cold storage is between 1 and 15 degrees Celsius, you can use the industrial cold storage above zero. Medicines and some food items are sensitive to sub-zero cold and lose their properties if they get too cold. For such products, industrial cold storage above zero is suitable. Industrial cold storage below zero For products that need a lot of cold and spoil at temperatures above zero, subzero industrial cold storage is suitable. Protein materials are among the products that should be kept at sub-zero temperatures. The compressor used in these cold stores is usually of multi-stage type. Double circuit industrial cold storage This type of industrial cold room has the ability to produce temperatures above zero and below zero. In this way, its usage can be easily changed. In case of change of use, it is better to completely empty and disinfect the cold storage and then use it. Advantages of industrial cold storage One of the advantages of industrial cold storage is to prevent spoilage of perishable food. Usually, the production of perishable food is much less if there is no industrial cold storage, and the possibility of shortage in the market increases. Among other advantages of these cold stores, we can mention their diversity. The dimensions of these cold stores can be very large, and there is also the possibility of producing fixed or mobile cold stores.
What is the difference between a refrigerator below zero and above zero?
• The compressor of the refrigerators is different from each other. In this way, the compressor below zero has less capacity and power than above zero. • The power of the compressor winding is the same in the cold room below zero and above zero. But because the sub-zero compressor has a lower discharge pressure, the diameter of the compressor cylinder has been designed to accommodate more gas. • The temperature of cold storages below zero is usually between minus 18°C and minus 20°C. But in cold storages above zero, the air temperature is from 1°C to 5°C and in some cases up to 10°C. there are. • The distance between the fins in cold stores is different. In this way, the distance between the fins above zero is slightly more than below zero. The reason for this distance is to prevent the formation of frost on the surface of the operator and to reduce the temperature of the cold room. • Cold rooms above zero are used to store fruits, medicine, vegetables, dairy products, etc. But below zero is used to store and freeze chicken, meat, fish, etc.
Capacity and temperature of the refrigerator above zero
The temperature of the cold room above zero is between 1 and 5 degrees Celsius. Of course, there are other samples that are rarely used and have a temperature between zero and 10 degrees Celsius. These types of cold stores have a capacity of 10,000 to 20,000 tons of refrigeration. The equipment used in this type of cold storage is similar to subzero cold storage. The only difference is the amount of energy used to control the ambient temperature, this type of refrigerator uses less energy to reduce its ambient temperature. It should be noted that the use of this type of cold storage is done in a short period of the year, and for this reason, there is no need to use some fluids and to insulate the walls.
