The emergence of new technologies, such as cold storage equipment, has created a great transformation in the industry, especially in the food, fruit and vegetable industries, etc. So that the lack of benefit from these technologies and refrigeration systems has become inevitable in most of the construction cases of the food industry and other industries.
Refrigeration and cooling systems such as cold stores are widely used for the purpose of taking care of food supply and demand market, storage of medicines, distillation and separation operations in the petrochemical industry, laboratory industries, etc. Cold storage is made in various designs such as connexion cold storage, chamber cold storage and industrial cold storage, and in sub-zero and above-zero types. The basic facilities used in all these cold stores include compressors, condensers, evaporators, control valves, electrical panels and protective facilities. In this article, we have explained these features and forms of high quality brands available in the market.
Refrigerator equipment
We can mention compressor, condenser, evaporator, switchboard and control and protection valves among the most important and prominent cold storage equipment. The performance of the cold room and its effective age mostly depend on the type of compressor, condenser, and evaporator, and these parts are the most expensive in the construction of the cold room. But in the cold storage of the connection, its body and the type of insulation used are also very important. Due to the very low cost of construction compared to industrial cold storage, cold storage facilities are widely used in different industries. In total, the different parts in cold storages are:
Cold room body and its type of insulation in cold room equipment The body of the cold room is a sandwich panel with a thickness of 10 to 15 cm. The type of insulation is polyurethane and the whole body is covered with a sheet cover. Cold room insulation debate is very important. Because the more comprehensive the insulation, the refrigeration systems will be less stressed and energy consumption will be saved. Also, perfect insulation, due to the avoidance of temperature fluctuations inside the freezer, helps the health of food, especially fruits and vegetables, in cold storages above zero, because in these types of cold storages, with an unwanted drop or rise in temperature, the negative effects of the bed Gas appears on productions.
The role of the compressor in cold storage equipment: The most important part and the beating heart of any refrigerator is its compressor. A compressor is a device that is used to compress gases. It is worth mentioning that in compressors, the operation of condensing and compressing gases causes the temperature of the gas to rise. Usually, this part is also called a cold storage engine. It should be mentioned that the electricity consumed by cold stores is three-phase industrial. But connexion freezers with single-phase electricity can also be insulated, but the cost of installing this type of cold storage is much higher than its three-phase type. Compressors are made in different shapes. For example, the most well-known compressor brands in the market can be Danfoss, Tecumseh, Bitzer, Copeland, etc.
Condenser in cold storage equipment: Condenser or the heat exchanger in the general situation are responsible for cooling the fluid and changing the phase of the refrigerant from gas to liquid. In cold storage, the condenser cools the hot and condensed gas caused by the compressor. This cooling operation is formed by water or air, which is known in the market as air condenser or blue color. In the cold room, the condenser transfers the heat of the freezer and the internal fluid in the compressor. The blue condenser transfers heat to water and the air condenser transfers heat to air. Air condensers are installed in the open space so that the cooling operation can be performed using the fresh air method. Condensers are usually sold together with corresponding compressors in the market under the title of distillation unit. Therefore, the companies that produce compressors, the compressors in the catalog of the device, provide the appropriate and recommended type of condenser.
