Design, consultation and implementation of all types of cold storage

We are all familiar with perishable products such as vegetables, fruits, etc.; In order to store these products so that they do not spoil and have a longer shelf life, they should be kept at a low temperature, which is possible by using a refrigerator. The cold room with its features can divide the cooling between different floors, which as a result makes these products last longer.

So, the most important and main advantages of cold storages is to prevent various products from spoiling, and of course, this is not the only case; This device should be able to maintain the quality of the products in case of spoilage, which is related to the points that were observed during the construction of the cold storage.

The main equipment of cold storages

Before going to the more complex discussions of cold storage design, it is better to be familiar with the main cold storage equipment. In fact, this equipment is the same in all types of cold storages and should be used in all of them. These equipments include:

• Compressors are one of the main components of every household, and actually increasing the refrigerant pressure is one of the tasks of these compressors.
• Cold storage condenser Another main equipment during the construction of the cold room is the one that is responsible for transferring the heat of the refrigerant to the outside of the cold room.
• The expansion device, which is also clear from its name, is used in cold stores to create a refrigerant pressure drop.
• The operator, which you are probably all familiar with, has the task of transferring the heat of the internal environment to the refrigerant; One of the other tasks of the compressor, which we explained above, is to remove the gases that are created from the operator’s side.
• A series of safety devices such as filters, service valves, electrical panels, etc.

Introduction of fixed cold storage

The most important use of fixed cold storage is to run small and medium cold storage. Products cannot be stored in large quantities in this cold store; Of course, for this reason, restaurants welcome this type of cold storage and use them to store their own products such as fruits.

Among the types of cold stores, fixed cold stores are among the most widely used and popular. Of course, apart from restaurants, they are also used in other places such as hotels, fast food, sandwiches, etc.

Fixed cold storage feature

To use a fixed cold storage, you first need to be familiar with the benefits and features of this cold storage, and then for Construction of cold storage Take action consistently. In the following, we will introduce you some examples of the most important features of the fixed cold storage:

• Despite their small size, fixed cold storages have high durability and strength.
• Due to their small dimensions, these cold stores can be produced in high tonnage.
• Fixed cold stores have the ability to run and install the unit, which means that they can be used separately from the body and the space around the cold store.
• Inside these cold storages, there are no floors with high tolerance; But it is possible to build heavy internal floors in fixed cold stores, and if needed, you can store products in large quantities by building these floors.

What are the disadvantages of fixed cold storage?

So far, we have learned about the advantages and features of the permanent residence; But it’s not like this cold store has only advantages and no flaws. Before designing the refrigerator, you should be familiar with their disadvantages so that you can buy the best type according to your needs.

Here are some examples of the most important advantages:

• If you need to move somewhere urgently, these cold storages are not suitable for you.
• You have to pay a lot of money for this when you move from one place to another.
• In the advantages section, we said that due to the small dimensions, it can also produce them in high tonnage. But if you use high tonnage, you must use concrete infrastructure.
• To protect the cold storage space, there are various problems that make the work a bit difficult.

Introducing the mobile cold storage

If you are planning to build a small cold room or a medium cold room inside the sheds or in a large space, the best choice for you is a mobile cold room, which is also known as a cold room.

As we have explained above in the fixed cold storage section, rooms are used in the design of a fixed cold storage, and this is the case when metal structures or sheds are used in mobile cold storage.

Investigating the use of mobile cold storage

We said above that fixed cold storages are used in restaurants, fast food, hotels, etc. due to their small dimensions. But the implementation of mobile cold storage is not for these places and they are used to store relatively more important products such as protein, pharmaceutical industries, dairy industries, etc.

Features of mobile cold storages

In this section, we want to take a look at the features of mobile cold storage, so that you can make a safer choice when buying or operating a cold storage. The following are among the most important features of these cold stores:

Mobile cold storage body

You probably noticed during your research that the body of each cold store is one of their most important parts. Therefore, in the construction of the body of the cold room, you must use sheets that provide the best feedback and actually prevent the penetration of heat and the exit of cold.

The body of most of this cold storage is usually made of sandwich panel. Sandwich panels have high resistance and long life and durability, and they have a very light weight and a beautiful appearance.

Determination of evaporator temperature and evaporator temperature difference

In order to absorb heat from the cooling fluid (for example, air in a cold room), the temperature difference must be Cold room evaporator be chosen correctly. The meaning of evaporator temperature difference is the temperature difference of the cooling fluid (like air in a cold room) and the surface temperature of the evaporator..

Choosing the right temperature for the evaporator is very important, because if this temperature is chosen lower than the right value, the temperature of the air coming out of the evaporator will be lower than the desired value. And vice versa, if the evaporator temperature is selected higher, either the heat transfer is not performed or this value is low and the output fluid temperature is higher than desired, which will be a problem in both cases.

The ability to move anywhere

Unlike fixed cold storages, which cannot be moved immediately, mobile cold storages can be moved quickly, and the moving process is easy. Because the components of the mobile cold storage are easily separated from each other.

Cold storage engine

The motors used in the mobile cold storage are from Danfoss or Copeland, which have a power of 1.5 horsepower.

Electrical panel

This other part depends on the expert’s skill at the time of building the cold storage; Because these electrical panels must be installed in a principled and high-quality manner, and the reason is that all the parts of the cold stores are placed on these electrical panels.
