Most people deal with equipment like refrigerators every day. But this technique is designed for the home. What devices are in production? After all, products are sold in large volumes.

What is this

Industrial refrigerators are entire structures that are a refrigerating chamber for cooling or freezing food. They may vary in size and temperature range. Usually it is from +4 to -40 degrees Celsius. Also, the capacity of the chamber can be different, usually this figure is calculated in tons:

- small refrigerators have a capacity of less than 500 tons;

- medium - no more than 5000 tons;

- large ones can hold more than 5000 tons of products.

Usually large refrigerators have several floors. It depends on their purpose and available space.

Easier to load and store products in low-rise chambers.

Humidity and temperatureof the refrigerating chamber depend on the technological process. Often, a brine system is used for cooling. With it, a brine of calcium chloride or table s alt circulates through the coils of the refrigeration unit. Along with such a system, there is an air system. Its principle of operation is similar to that of a fan, it creates enhanced air circulation.

Also, industrial refrigerators can have various active ingredients, from helium and ammonia to freon and carbon dioxide. All of these substances are capable of receiving a significant amount of heat.

The quality of refrigeration equipment largely depends on its thermal insulation.

It must be produced in a quality manner. The coefficient of thermal conductivity should be within the range of 0.029 - 0.116 W / (m • K). Insulation can be made from various materials (slag wool, polystyrene, aluminum foil, etc.), as long as it fulfills its intended function.

The tightness of the door is one of the conditions for the good operation of the refrigerator compartment.

There are industrial refrigerators that provide a certain temperature for a particular production process. They are mainly used in the wine industry, when the wine must mature under special conditions. Such refrigerators can be gigantic in size, usually they are concrete, in which the optimum temperature and humidity are maintained.

Types of equipment

Refrigerators that consume large amounts of electricity are not cost effective.

This is compressor equipment and refrigerant-free Peltier refrigerators.

Industrial refrigerators can be made not only with the installation of a refrigerant, but also with other heat sources, it can be produced by diesel fuel, gasoline or gas. There are varieties of dual-power refrigerators, as well as modern options that run on alternative energy sources - solar or mass heat.

Terms of Use

Safety and proper operation will allow the equipment to serve for a long time. If there is a violation of the norms, then repair of industrial refrigerators may be required. This is a very expensive procedure, in order to avoid it it is better to follow the rules:

- Do not store non-food and hazardous to human he alth substances together with food. This condition is protected by law.

- Any item in the refrigerator must be marked.

- All chemicals must be sealed.

Sandwich panels as a material for industrial refrigerator

This is a material containing a layer of thermal insulation, which allows you to perform structures with maintaining optimal humidity and temperature conditions. Refrigerators from such panels can be of two types: stationary or collapsible.

The second option is more often used, as it allows the installation of such equipment anywhere, and if necessary, it is possible to dismantle it andmove to another.

Stationary cameras require the approach of specialists to their design. Its design must comply with all production standards, take into account the occupied area and cost costs.

Proper installation of industrial refrigerators from sandwich panels can only be done by specialists in this field. They can make the necessary calculations to select the panel thickness. It will depend on what temperature is needed in the chamber itself, what will be outside, on the volume of the chamber and the products that will be stored in it.

Types of installations

Refrigerating units for industrial refrigerators are divided into two main types:

- absorption;

- compressor.

Installations of the absorption type heat up a special substance - absorbent - and condense refrigerant vapor from it. This view, in turn, is divided into:

- continuous operation - such installations can be diffusion or pumping;

- periodical action.

Absorption plants are large and consume large volumes of water. But they have an advantage over compressors in the simplicity of the device, noiselessness, reliability of components and the use of cheap forms of energy.

The compressor type plant is also a steam condensate machine.

It uses substances that effectively absorb heat - ammonia or freon. Such installations are divided into:

- sealed;

-semi-sealed;

- open.

Cost of the refrigerator compartment

The price category of industrial equipment will depend on what type of cold store the company needs.

A refrigerator of medium size 1960x2860x2200 mm will cost about 80 thousand rubles. Such equipment can be ordered from the manufacturer ASK-holod LLC.

It is possible to buy industrial refrigerators, the price of which will be lower, but the volume of the chamber will change. That is, the cost directly depends on the dimensions. For example, a refrigerating chamber 3160x5260x2200 mm from the same manufacturer will already cost about 130 thousand rubles.

Fridge Compressor

In order for the refrigerant vapors to be compressed and circulated, a special compressor is used for an industrial refrigerator. Such a device is divided into the following types:

- rotary;

- piston;

- centrifugal.

When purchasing such a device for a refrigerator, you need to familiarize yourself with the principle of its operation and with what substance it works. There are two types of compressors according to the type of refrigerant:

- working on freon;

- on ammonia.

Ammonia compressor requires additional equipment as it generates high temperatures.

But the element with freon can work with air flow.

Cost

Its price category depends on which refrigerator it is inwill be installed.

Namely, what volume will need to be cooled. Huge refrigerators require more than one element. The compressor and condenser unit ACC TFH4524 ZHR (medium temperature) will cost 90 thousand rubles. There are also more expensive ones. The two-compressor unit AMK-H-2-4CC-6.2 can be bought for about 760 thousand rubles.

So, we found out what refrigeration units for industrial refrigerators are and how much they cost.
