A vacuum refrigeration system consists of a large insulated flash chamber kept at low pressure by steam ejector which pumps vapor to a condenser. Condensate is removed by condensate to an air vent. Warm return water enters the flash chamber at 13oC, chilled water comes out of the flash chamber at 5oC Vapor leaving the flash chamber has a quality of 0.97 and the temperature in the condenser is 32oC. For 350 kw of refrigeration How much vapor must the steam ejector remove from the flash chamber?
