A Cold Room Refrigeration Unit is a system used to maintain the temperature of a room or space at a constant level. This unit is typically comprised of a compressor, condenser, evaporator, and expansion valve. The compressor compresses the refrigerant, which is then passed through the condenser to cool the refrigerant. The cooled refrigerant then passes through the evaporator, where it absorbs heat from the air in the room or space. The hot air is then expelled from the unit and the cooled air is then circulated throughout the room. Cold Room Refrigeration Units are used in various applications such as in industrial and commercial buildings, restaurants, and warehouses.
