A refrigerant vapor compression system includes a compression device having at least a first compression stage and a second compression stage arranged in series refrigerant flow relationship. A first refrigerant heat rejection heat exchanger is disposed downstream with respect to refrigerant flow of the second compression stage. A first refrigerant intercooler is disposed intermediate the first compression stage and the second compression stage. The first refrigerant intercooler is disposed downstream of the first refrigerant heat rejection heat exchanger with respect to the flow of the first secondary fluid. An economizer includes a vapor line in fluid communication with a suction inlet to the second compression stage. A second refrigerant heat rejection heat exchanger is disposed intermediate with respect to refrigerant flow of the second compression stage and the first refrigerant heat rejection heat exchanger. A second refrigerant intercooler is disposed intermediate the first compression stage and the second compression.

A compact heat exchanger assembly for a refrigeration system includes a heat rejection heat exchanger assembly and a heat absorption heat exchanger assembly. The heat rejection heat exchanger assembly includes a primary heat exchanger and a secondary heat exchanger. The primary heat exchanger has a tube bank extending between a first manifold and a second manifold. The tube bank being provided with at least one bend such that the primary heat exchanger has a generally curvilinear shape. The secondary heat exchanger is disposed between the first manifold and the second manifold.
