Refrigerated Cabinet

an insulated refrigerated box with doors. Refrigerated cabinets are widely used for the short-term storage of perishable products in stores and in food service enterprises. The inner and outer cases of such cabinets are made of steel, aluminum, or plastic. A layer of low-temperature insulation 50–100 mm thick is placed between the cases. The doors either are insulated and made entirely of metal or consist of double or triple glass. Shelves, racks, or trays for products are inside the cabinet, which is cooled by means of a small refrigerating machine with a built-in or separate refrigerating unit. Depending on the temperature in the cooled space, a distinction is made between medium-low-temperature (1°–3°C) and low-temperature (not above – 18°C) refrigerated cabinets.

The volume of the cooled space in Soviet commercial refrigerated cabinets ranges from 0.4 to 1.6 cu m. Refrigerated cabinets with thicker low-temperature insulation and higher-capacity refrigerating machines are used in laboratory practice and for industrial purposes, such as the cold quenching of tools or the accelerated aging of various parts.
