Industrial refrigeration is defined as a closed environment that has a temperature lower than its outside temperature. This temperature difference is significant and large and is designed to protect the contents inside the refrigerator or prevent it from spoiling and keep them in the desired environmental conditions. In fact, since the 19th century, refrigeration and freezing of food has been done mechanically with the help of ammonia, but the method of this refrigeration in cold stores has been constantly synchronizing and adapting to the needs of the day and resources.
Refrigerators are classified according to different criteria. From these criteria can be
- Temperature suffering
- Application
- Structure
- Dimensions
- Insulating and procedural features
- Staying or moving
- Product type stored
- Special features
Cited. Among these, industrial cold storage is a large-sized cold storage that is generally used for commercial and industrial purposes and has a high loading volume. Industrial refrigeration is used to store fruits, nuts, meat, fish and other food items such as vegetables, medicines in large dimensions. These types of refrigerators are usually located next to fishing centers, slaughterhouses, gardens and the like, and are a large space consisting of several rooms where the temperature and humidity of all rooms can be adjusted by the control room.
Industrial refrigerators are also used for home appliances, automotive industries, data centers and information processing centers.
Refrigerators are classified into different types based on different criteria.
Types of fixed or movable industrial refrigerators
It has been said that the most important use of industrial refrigerators is for goods and products that, if not in the refrigeration environment, lose their freshness, deteriorate or are physically and chemically damaged. Therefore, for these cases, refrigerators are designed and built in a fixed manner near the production site or near the depot. At this stage, a room in the form of a warehouse or a larger place in the form of a building is installed to build a cold storage, then the necessary equipment to build a cold storage is brought to the same place and the cold storage is gradually built there as part of the structure. .
However, there is not always the opportunity to store products in a fixed location or there is basically no storage space from the beginning. In these cases, a mobile industrial refrigerator is used. Sometimes portable, industrial refrigerators are essentially needed, regardless of space. In this way, the refrigerator is made in the form of a container and installed on the site. Therefore, it is portable and removable when necessary. In this case, the ready-made industrial refrigerators produced in the factory can be purchased and brought to the project site.
