Claim Text:
1. A refrigerant vapor compression system comprising: a first refrigerant heat rejection heat exchanger having a refrigerant inlet and a refrigerant outlet; a second refrigerant heat rejection heat exchanger having a refrigerant inlet and a refrigerant outlet; a refrigerant compression device having a first compression stage and a second compression stage; a branch refrigerant line connecting a refrigerant inlet of the first compression stage to a refrigerant inlet of the second compression stage; a flow control device in the branch refrigerant line; the first and second compression stages and the first and second refrigerant heat rejection heat exchangers selectively configurable in a first arrangement wherein the first and second compression stages operate in a series refrigerant flow relationship and the second refrigerant heat rejection heat exchanger functions as an intercooler for cooling refrigerant passing from the first compression stage to the second compression stage, the flow control device closed in the first arrangement, and in a second arrangement wherein the first and second compression stages operate in a parallel refrigerant flow relationship and the second refrigerant heat rejection heat exchanger functions as a gas cooler for cooling refrigerant passing from the first compression stage, the flow control device open in the second arrangement.
