Medium Temperature Refrigerated Display Cabinets

Trade refrigeration equipment serves not only to store food products under certain conditions, but also is an excellent marketing tool that allows to represent goods in a more favorable light. A separate class of such units are mid-temperature refrigeration showcases intended for short-term storage and laying out of many food groups of goods.

This climatic class of showcases is equipped with refrigeration units capable of maintaining a temperature in the internal volume of 0 ... + 8C. They are great for storing sausage, dairy and cheese products, as well as salads and semi-finished products that do not require pre-freezing.

Medium-temperature refrigeration cabinets can be equipped with a blind front glass, or a front part, which can be opened if necessary, which provides additional convenience for potential buyers. The design of the units can include both built-in and remote units, which ultimately will determine the dimensions of the display case, as well as some features of maintenance and repair. Special attention should be given to the quality of thermal insulation, as well as the design of the evaporator when choosing a technique.

The heart of any refrigerated display is a compressor. For medium-temperature models, the optimum refrigerating capacity is 600-100 W depending on the size of the unit, as well as on the evaporation temperature of the refrigerant and the external operating conditions.

The design of showcases uses the principle of natural or forced air circulation. Accordingly, the cooling of the internal volume of such equipment will be dynamic or static. Models with forced circulation provide a more even distribution of the cold inside the unit, so this equipment costs a little more.

One of the most important criteria for aggregates is the depth of the computation. Equipment with a large enough exposure area pays off more quickly, however, in retail premises with a limited area it is worthwhile to use more compact showcases. The most advanced models of mid-temperature units are equipped with front glass preheating systems, automatic defrosting, and multifunctional control and control units.

It is necessary to separately note the way of organization of cooling production of medium-temperature equipment. Showcases equipped with built-in units are comparatively cheap and easy to install, but they work more noisily and require the use of additional conditioning to organize proper heat removal. Models with remote units tend to have a greater depth of computation due to the lack of hardware in the design. In addition, compressor installations in remote systems have a much greater service life than a technique equipped with built-in cold.

Large supermarkets and trade enterprises that have capacious trading halls prefer to use showcases that can be connected to the central cooling system. This solution allows the use of heat generated by the units for heating the premises, and also provides the possibility of simultaneous connection of a sufficiently large number of equipment.
