Abstract
Embodiments of the present disclosure are directed to a heat exchange device that includes a condenser configured to receive a refrigerant, an evaporator having an evaporation tube bundle, a throttling device configured to receive a first portion of the refrigerant from the condenser and to expand the first portion of the refrigerant before directing the first portion to the evaporator, and an ejector having a high pressure conduit, a low pressure conduit, and an outlet conduit, the ejector is configured to receive the first portion from the throttling device or a second portion of the refrigerant from the condenser via the high pressure conduit, receive a third portion of the refrigerant from the evaporator via the low pressure conduit, mix the first portion or the second portion with the third portion to form a mixed refrigerant, and direct the mixed refrigerant to the evaporator via the outlet conduit.
