Abstract
A multistage refrigeration system is provided. The multistage refrigeration system includes a first stage system and a second stage system connected by a multi stage heat exchanger. A heat exchanger connected to either one of the first or second stage system is disposed within a receiver of the second stage system. In an exemplary embodiment, the heat exchanger is a first stage evaporator, such that the receiver functions to transfer heat between the stages of the multistage system and to accumulate a reservoir of liquid refrigerant for distribution through the second stage system.
