ABSTRACT:
A coaxial economizer for use in a chiller system comprising an inner housing and an outer housing having a common longitudinal axis. The outer housing has an inlet for receiving a fluid from a upstream compressor stage of a multistage compressor and an outlet for conveying a fluid to a downstream compressor stage of a multistage compressor. A flow chamber forms a fluid flow path about the inner housing. A flash chamber is coterminous with the flow chamber and flashes fluid in a liquid state to a gas state. A flow passage between said flash chamber and the flow chamber for conveying a flashed gas from the flash chamber to the flow chamber; wherein the flashed gas conveyed from the flash chamber and the fluid received from the inlet of the outer housing mix along the fluid flow path toward the outlet of the outer housing.
