What is refrigeration equipment?

Refrigeration equipment is a device that combines a refrigerator with a facility that uses cold capacity. Design and construct refrigeration units for the efficient use of cold energy to refrigerate food or other items; Carry out product performance test and scientific research test at low temperature; In industrial production, certain cooling processes are implemented, or air conditioning is performed.

When the item is cooled or frozen, a certain amount of heat should be released, and the enclosure structure of the refrigeration device will also introduce a certain amount of heat when it is used. Therefore, in order to maintain the low temperature conditions in the refrigeration unit, a refrigerator must be installed in order to continuously remove this heat, or use the melting of ice or the sublimation of dry ice to absorb this heat.

How many kinds of cooling methods are there for refrigeration equipment?

There are two kinds of cooling methods of refrigeration equipment: direct cooling and indirect cooling. Direct cooling is to install the evaporator of the refrigerator in the box or building of the refrigeration device, use the evaporation of the refrigerant to directly cool the air, and rely on cold air to cool the object that needs to be cooled. The advantages of this cooling method are that the cooling speed is fast, the heat transfer temperature difference is small, and the system is relatively simple, so it is widely used. Indirect cooling depends on the evaporation of the refrigerant in the evaporator of the refrigerator, so that the refrigerant (such as brine) is cooled, and then the refrigerant is input into the box or building of the refrigeration device, and the air is cooled through the heat exchanger. This cooling method has a slow cooling speed, a large temperature difference in total heat transfer, and a complex system, so it is only used in fewer occasions, such as brine ice making and cold storage with constant temperature requirements.

According to the different purposes of cooling and the use of cold capacity, refrigeration devices can be broadly divided into four categories: refrigeration devices for refrigeration, refrigeration devices for testing, refrigeration devices for production and refrigeration devices for air conditioning.

Refrigeration refrigeration equipment is mainly used to store or transport food and other goods at low temperatures, including various refrigerators, cold storage, refrigerated trucks, refrigerated ships and refrigerated containers.
