Industrial Refrigerators

Industrial refrigerators are also referred to as industrial cooling machines. Industrial chillers are used to maintain products at extremely low temperatures. The temperature range of these refrigerators is usually -20 or lower than that. Blood Station is widely used in hospital, medical stations, epidemic prevention centers, research institutes, electronic industry, chemical medicine, biological engineering, higher laboratory, military enterprise, etc. It is suitable for use in many institutions and organizations.

 

Since the required coldness is relatively lower than that of household refrigerators, energy consumption is higher. Since industrial refrigerators require different degrees of coldness depending on the area to be used, the machines to be supplied differ from each other. Industrial refrigerators generally use layered cooling technology, so the cooling effect is better, the noise is less and maintenance is easier.

Industrial Refrigerators and Types

As its name suggests, it is an industrial machine used to keep production products that need to be kept cold at a certain temperature. These materials often include food, agricultural products, proteins and pharmaceutical products. Industrial refrigerators may also be needed in many other places, such as chemical and military industries. Some industrial refrigerators are portable and some are fixed.

 

History of Cooling

Food preservation is a method used by human beings for a long time. Storing some food products in cold places to protect them from dirt or to prevent these products from spoiling has been used since ancient times. The use of snow and natural ice molds is one of the examples that can be considered in this regard. However, with the advancement of technology, the industry has also made significant strides in the construction of cooling devices. The first machines began to be made in the late 19th century. In these devices, ammonia or water gas was used to produce cold air. Then, an odorless gas that had an ideal performance in creating destructive cycles was used. In addition, the problem of poisoning with this gas was eliminated.

 

The introduction of gas into the prophylactic industry further expanded the industry and the first industrial and household refrigerators were produced in this way. However, in 1985, it was announced in the Vienna Convention that some countries would limit the use of free gas due to environmental problems. The same substance has caused manufacturers to turn to other refrigerants and produce different refrigerants with different chemical formulas.

 

Although construction of the refrigerator began in the late 19th century, it took more than thirty years for it to be officially built. Ammonia gas was used in France, and later Americans also used it as a refrigerant. In 1900, tracheal cooling devices entered the commercial market and were used in the food, chemical and ice industries.

 

The first basis of classification of industrial refrigerators is the temperature range. In general, industrial cold storages are divided into two main groups:

Above Zero Industrial Refrigerator
Subzero Industrial Refrigerator

Below, we will introduce and review the details of these two types of industrial refrigerators.

 

Above Zero Industrial Refrigerators

Keeping some food products and medicines below zero temperature can destroy the chemical and physical texture of the product and reduce its quality. In such cases, employers turn to refrigerators that do not have a freezing effect. The temperature range of these refrigerators usually fluctuates between 0 and +15 degrees Celsius. Choosing the temperature range depends on the efficiency of the refrigerator and the main purpose of its installation. The most important use of high temperature refrigerators is when you want to store a product for a short period of time. In maximum mode, this period may not exceed fifteen days. Agricultural products, fruits and vegetables are often stored in this type of industrial refrigerators. In such cases, the temperature of the product should not reach freezing point. Other products kept in high-temperature refrigerators include products such as dairy products, proteins, medicines, flowers and plants.

 

Subzero Industrial Refrigerators

The main purpose of these refrigerators is food, agriculture, etc. is to freeze its products. The average temperature range for these refrigerators is between -12 and -3 degrees Celsius. Multistage compressors are used in subzero refrigerators. In these compressors, the process of compressing the refrigerant is carried out in several stages, and as a result, the temperature of the refrigerant when leaving the compressor is not too high, which has a positive effect on the cooling performance of the compressor. In general, the liquid circulation rate in subzero industrial refrigerators is faster.
