How to choose refrigeration equipment article. How to choose the right refrigeration unit for the distribution cabinet

To store food in accordance with sanitary standards, it is necessary to purchase industrial refrigeration equipment for industrial and commercial facilities. The list of industrial equipment is much wider than household equipment: it includes not only refrigerators and freezers, but also refrigerated cabinets, display cases, special chest freezers, shock freezers and dozens of other types of equipment. It protects food and beverages from spoilage, ensuring compliance with the temperature regime of storage.

Industrial refrigerators and freezers are selected taking into account several more parameters that determine the convenience of their operation. Pay attention to the following features:

1. The presence of a control panel with indicators. A convenient panel simplifies and speeds up temperature setting, in addition, it allows you to control the operation of the refrigerator.
2. Recessed handles for opening compartments. This is an important difference from household refrigeration units: A household refrigerator has external opening handles, while an industrial one has recessed ones. This eliminates collision with carts and simplifies the movement of personnel.
3. Compressor location. It is better to purchase a refrigerator or freezer with a top-mounted unit: it provides free access for maintenance and repair, it suffers less from pollution.
4. The presence of a self-diagnosis system. With it, you can quickly identify and fix the problem to return the equipment to work.

Also in our catalog it is proposed to pick up a cash box for shops and other types of commercial equipment for points of sale of various sizes. All offered furniture and appliances meet the highest quality and reliability requirements.

According to experts, properly selected refrigeration equipment can increase sales of goods several times in both small retail outlets and large supermarkets.

Refrigeration equipment performs a number of functions related not only to the storage of products, but also to their pre-sale demonstration. In addition, it plays an important role in creating the design of the room.

The modern market of refrigeration equipment is saturated with a wide variety of models of refrigerated display cases. Choosing the right option is not an easy task. There are several factors that must be considered first of all when selecting this category of refrigeration equipment.

Universal and specialized refrigerated display cases.

The first point is technical. Modern refrigerated display cases can be divided into two main categories - universal and specialized.

• The first category of equipment is suitable for storing and displaying most food products sold at catering establishments and retail outlets.
• The second category is designed to store only certain types of goods. The main difference between the two categories of refrigeration equipment is the method of loading the goods, the depth of its display, the possibility of connecting external cold and a special drive.

An important point is the correct determination of the required mode of cooling goods. There are showcases with dynamic and static cooling principle.

• In the first variant, the supply of cold is carried out with the help of a special fan, which distributes cold air currents inside the showcase.
• In the second case, the cold is distributed evenly throughout the territory. Different categories of food products imply certain storage conditions.

Refrigerating show-windows with the portable and built-in cold.

The second point to which attention should be paid is the type of activity and the enterprise itself. Small retail outlets and large supermarkets require refrigeration equipment with different temperature conditions and different refrigeration systems. Refrigerating show-windows can be both with built-in, and with remote refrigerating units. Remote refrigeration is usually used in large supermarkets. This is primarily due to the fact that a separate room is required to install such a cooling system, and there is also a need for additional work.

The temperature regime of the refrigerated showcase can be medium temperature or low temperature.

• The first group of equipment is intended for the storage of non-frozen products. This category of goods includes, for example, sausages, already prepared salads, dairy products, semi-finished products.
• Low-temperature refrigerated showcases are designed for demonstration and storage of frozen products - meat, fish, seafood.

Design and type of refrigerated showcase.

When choosing a refrigerated display case, one should take into account the size of the retail space and the specifics of the enterprise. It is important to correctly determine the location of the refrigeration equipment. If the outlet is small, then to create an optimal flow of customers, it is better to choose wall-mounted refrigerated display cases. If the outlet has an impressive area, you can use another type of refrigerated display cases - island ones. Such equipment is located in the center of the room.

The specifics of the goods should be taken into account when choosing a model of a refrigerated display case. Closed showcases are ideal for storing frozen food, and open ones are ideal for displaying fresh goods or products that do not require prior freezing.

Value for money refrigeration equipment.

The third point, which is no less important, is the cost of refrigerated display cases. This category of equipment is divided into several classes:

• "economy";
• "business";
• "lux".

The equipment of the "luxury" class has the highest technological characteristics. "Economy class" is presented, as a rule, in the form of equipment with built-in refrigeration units and mechanical control systems. "Business class" is equipment with both built-in and remote cooling systems, it has a special electronic control unit.

Among the manufacturers of modern refrigerated display cases, some brands known all over the world can be distinguished. For example, the trademarks Unis, Gulfstream, Elektrolux, Polair, Polyus have been recognized by consumers for many decades. These manufacturers supply the market with both economical options for refrigerated display cases and elite expensive refrigeration equipment.

Quality refrigeration equipment is made of stainless steel, polyurethane and plastic of the highest quality. Modern manufacturers of refrigerated display cases offer their customers not only a wide range of refrigeration equipment, but also provide after-sales support, give a factory warranty for components and assemblies.

You can consult on all your questions on the Refrigerated Showcases website. Here you will always find the best solution for your business. It is enough just to determine the needs and specifics of your business.

What are the main criteria for choosing refrigeration equipment? What should you pay attention to when buying it. In this article, we will consider the main points that you should pay attention to when choosing this commercial equipment.

Your product will be of interest to customers only if it is in all its glory - fresh and pleasant to look at. Refrigeration equipment performs not only the function of storage, but also presents products in the best light. There are two types of refrigeration units: cabinet and chamber.

Refrigerator and chamber

The refrigerator is immediately ready for use after unpacking. It is designed for a small number of products. In turn, the cold room consists of prefabricated elements: panels and modules are already assembled at the installation site. Accordingly, its volume can vary and be significantly higher than the volume of the refrigerator.

Refrigeration equipment temperature

Medium-temperature equipment includes a refrigerated display case, chests and cabinets. They are intended for short-term storage of refrigerated goods. Long-term storage is possible only in sealed packaging of products with the required shelf life. The temperature of the refrigerating chamber of this type ranges from 0 to 10C.

Low-temperature refrigeration equipment is designed for frozen goods. Temperature range: 0 - -18 C.
The combined type of equipment includes:

• Combined freezer that supports different modes in different chambers.
• Refrigerating chamber with a transition mode: -5 - +5 C. Such equipment keeps vegetables, fresh meat and fish well.
• Wine cabinet with its own temperature regime at different levels.

When choosing refrigeration equipment for a store, look at temperature controllers. Settle on regulators with small steps. In this case, you can choose the ideal mode for each product even in small temperature ranges.

Requirements for refrigeration equipment

There are seemingly insignificant details that can help in choosing freezing equipment:

• Choose refrigerated cabinets with recessed handles, not protruding handles - they will not interfere with carts and staff to move freely in the room.
• Pay attention to the indicators: how detailed they reflect the condition of the equipment. The self-diagnosis function is very useful.
• Choose equipment with a refrigeration unit located at the top - it will be less contaminated and easier to reach in case of a problem.

Choice of refrigerant and compressor

The main requirement for the refrigerant is environmental friendliness. Modern commercial refrigeration equipment contains ozone-friendly refrigerants R404a and R134a.
The compressor must meet the following requirements:

• Low noise level.
• Power capable of sustaining continuous, trouble-free operation.

Rules for storing food in a refrigeration unit

Before choosing refrigeration equipment for a store, study the rules for storing food:

• Products are stored according to the classification: bakery products, dairy products, fish, dry products, vegetables, fruits.
• Specifically smelling products (fish, spices) must not be stored next to products that easily accept odors (flour, cheese, salt, etc.)
• Choose refrigeration equipment with easy-to-clean racks with a condensate drainage system.
• Finished products and raw materials are stored separately.
• Deep-frozen foods can be stored nearby.
• Choose stainless steel cookware. It does not change the properties of the products.

When choosing industrial refrigeration equipment for your business, you need to determine the main task that your industrial refrigerator will perform in the future. For each of the tasks there will always be several solutions, we need to choose one - the optimal one. To do this, when choosing industrial equipment, it is worth considering some factors that affect the performance of the system and its efficiency.

To make the right choice of industrial refrigerator you need to know:

Maximum heat dissipation;

How does heat release change during the working day;

Hydraulic system resistance;

Where will the heat be removed?

The need for duplication of the system.

It is often more profitable to put more than one installation, but to break it down by performance. In this case, all installations can work during the day shift, but at night, on weekends and holidays, a small machine is quite enough. This will allow you to save on the operation of the system, as well as increase the reliability of the cooling system.

The choice of a pump, the main task of which is to pump the coolant, is influenced by the following factors: the distance from the industrial refrigerator to the place of consumption, the diameter of the pipelines, and the need to raise this very liquid to a certain height.

The system can also be equipped with refrigeration equipment, which will be in stock. It is advisable to do this if the cost of production downtime is commensurate with the cost of equipment. In this case, electronic control units are installed on the units, which are able to automatically regulate the operation of refrigeration machines so that the operating hours are the same.

It is unacceptable to select industrial refrigerators with a powerful electric drive with a performance that exceeds the required level. Why? Because sometimes customers buy refrigeration equipment "for the future", expecting that after a while they will need large capacities. For example, they buy a refrigerator with a very high (yet not needed) cooling capacity, hoping that in the future additional equipment will be produced that will require water cooling. It would seem that the calculation is correct. Having bought a more powerful industrial refrigerator today, you can be sure that tomorrow it will be enough for new equipment. However, a problem arises. If the cooling capacity of the equipment is much greater than the heat load, the refrigerator will turn on/off frequently. And for equipment with a powerful electric drive, there is a limit on the number of starts per hour. What caused it? The fact that at each start the equipment operates in the most unfavorable mode: starting currents exceed the rated current up to 10 times, and, accordingly, the heat dissipation of the electric cable can be 100 times higher than when operating in the rated mode. The increase in current at start-up leads to an increase in torque, which in turn leads to dynamic shock to the couplings, bearings and shaft at each start. Consequently, even the most reliable industrial refrigeration equipment will not be able to serve you for a long time, and the cost of its operation (the cost of energy consumed) will increase several times.

The optimum performance level of industrial refrigeration equipment is achieved when operation is continuous throughout the entire shift. To do this, it is necessary to select the refrigeration unit in such a way that it barely covers the maximum heat flow. In addition to the exact selection of equipment performance, you can also consider various methods for reducing the frequency of starts. One of such ways is to increase thermal inertia in circulating water supply systems by introducing a container with a coolant into the system, which will work as a "cold accumulator" and will increase the time between starts.

When an industrial refrigerator takes heat from the cooled liquid, it needs to use this heat somewhere, in other words, “throw it away”. And the heat emission, depending on the power of the installation itself, can be very large.

There are 3 options for solving this problem:

Heat emission to the street (using a remote condenser);

If the enterprise operates in the cold season, then for its system it is necessary to provide for the possibility of starting (winter start-up system).

Emission of heat into the workshop (monoblock version of the refrigerator);

This option can be used if the generated heat, when dissipated throughout the space of the room, does not cause a significant increase in temperature. And in some cases, it even allows you to save on heating the workshop.

Emission of heat to a place where it is needed (energy recovery).

If there is a place nearby where there is a need for heat (for space heating), then in some cases it is advisable to transfer this heat there using a heat carrier.

So, the question of which system is better to choose is desirable to decide even before the production line is put into operation.

We sincerely hope that this article will help you make the right and informed choice of industrial refrigerator.
