Abstract

See full text

A modular refrigeration system includes a refrigeration loop having a compressor, a condenser, an expansion assembly, and a chiller interconnected by a first piping loop cycling hydrocarbon refrigerant. A high side cooling loop includes a first heat exchanger and a first pump interconnected with the condenser by a second piping loop cycling a cooling fluid, the cooling fluid exchanges heat with the hydrocarbon refrigerant at the condenser. A low side cooling loop includes a second heat exchanger and a second pump interconnected with the chiller by a third piping loop cycling a chilled fluid, the chilled fluid exchanges heat with the hydrocarbon refrigerant at the chiller. A space supports the second heat exchanger and is configured to be maintained within a predetermined temperature range, wherein the total charge of hydrocarbon refrigerant associated with the space does not exceed 150 grams.
