  • heat exchanger devices can be used in air coolers to cool the air in large-volume rooms, such as walk-in storage or cold storage rooms.
  • the air coolers used for this purpose are part of the equipment of the storage or cold storage room and are installed stationary therein.
  • the air cooler contains a heat exchanger, e.g. in the form of a heat exchanger, past or through which the air to be cooled is passed, whereby the heat exchanger extracts heat from the air and cools it.
  • the heat exchanger can be a heat exchanger that has a pipe or duct system through which a coolant or refrigerant flows.
  • the heat exchanger can also be an evaporator that has a pipe or duct system through which a two-phase refrigerant flows.
  • the evaporator's piping or duct system is coupled to a compressor and a condenser or dry cooler, which is usually located outside the space to be cooled (e.g., on the roof of the building containing the storage or cold storage room).
  • the condenser or dry cooler is connected to the air cooler's evaporator via piping to convey the refrigerant in liquid form and at low pressure through the evaporator.
  • the initially liquid refrigerant evaporates, extracting heat from the flowing air.
  • the evaporated refrigerant is returned via the piping to the compressor and the condenser or dry cooler, where it is liquefied or cooled by compression.
