Steam ejector system

without comments

The low pressures (8–22 mbar) required to evaporate water as a refrigerant at 4–7°C for air-conditioning duty can be obtained with a steam ejector. High-pressure steam at 10 bar is commonly used. The COP of this cycle is somewhat less than with the absorption system, so its use is restricted to applications where large volumes of steam are available when required (large, steam-driven ships) or where water is to be removed along with cooling, as in freeze-drying and fruit juice concentration.
