A vacuum refrigeration system consists of a large insulated flash chamber kept at a low pressure by a steam ejector which pumps vapour to a condenser. Condensate is removed by a condensate to an air vent. Warm retum water enters the flash chamber at 13°C, chilled water comes out of the flash chamber at 5 C. Vapour leaving the flash has a quality of 0.97 and the temperature in the condenser is 32°C. For 350 kW of refrigeration.
