Climate control systems having ejector cooling for use with moderate to high glide working fluids and methods for operation thereof

Abstract

Climate control systems, like reversible heat pumps, circulate a working fluid having moderate to high glide with first and second refrigerants having a difference in boiling points ≥about 10° F. (1 atm.). The system includes a gas-liquid separation vessel, a compressor, a first heat exchanger disposed downstream of the compressor that generates a first multiphase or liquid working fluid stream, an expansion device, a second heat exchanger that receives and at least partially vaporizes a reduced pressure stream from the expansion device to generate a second multiphase or vapor working fluid stream; an ejector component disposed downstream of the first and second heat exchangers that receives and mixes the first stream and the second stream to generate a third multiphasic fluid stream that is directed to the gas-liquid separation vessel; and a fluid conduit for circulating the working fluid. Methods of operating such climate control systems are also provided.
