摘要： A refrigeration system is provided, such as for use with chillers. The system uses a tube-side condenser (24), such as a microchannel condenser, along with a shell-side evaporator (32) such as a falling film evaporator. A flash tank economizer (26) is disposed between the condenser and the evaporator, and an inlet valve (28) to the flash tank is controlled based upon subcooling of condensate from the condenser. The vapor exiting the flash tank may be fed via an economizer line to a system compressor. Liquid phase refrigerant combined with some gas phase refrigerant exits the flash tank and is directed through an orifice (30) before entering the evaporator.

摘要： A system includes a high side heat exchanger (105), a flash tank (115), an air conditioner load (150), an air conditioner ejector (205), a refrigeration load (120), a first compressor (130), a second compressor (140), and a vapor ejector (150). The high side heat exchanger (105) removes heat from a refrigerant. The flash tank (115) stores the refrigerant from the high side heat exchanger (105). The air conditioner load (150) uses the refrigerant from the flash tank (115) to remove heat from a first space proximate the air conditioner load (150). The air conditioner ejector (205) pumps the refrigerant from the air conditioner load (150) to the flash tank (115). The refrigeration load (120) uses the refrigerant from the flash tank (115) to remove heat from a second space proximate the refrigeration load (120). The first compressor (130) compresses the refrigerant from the refrigeration load (120). The second compressor (140) compresses a flash gas from the flash tank (115). The vapor ejector (110) pumps the refrigerant from the refrigeration load (120) to the flash tank (115).
