Claim:
1. A refrigeration system comprising: a refrigeration loop including a compressor, a first heat exchanger, and an expansion assembly, and a second heat exchanger interconnected by a first piping loop, the first piping loop circulating a hydrocarbon refrigerant; and a cooling loop circulating a cooling liquid in direct heat exchange relationship with the hydrocarbon refrigerant within the second heat exchanger, the cooling loop including a pump configured to circulate the cooling liquid through the cooling loop and interconnected with the second heat exchanger and a third heat exchanger by a second piping loop, wherein the first heat exchanger is in heat exchange relationship with an airflow passing through the first heat exchanger, and wherein the airflow is in communication with a space adapted to support product to be cooled, and wherein the third heat exchanger rejects heat to an ambient environment.
