A cooling system includes a unit for processing product to be cooled or frozen. A secondary refrigeration loop is connected to this unit and introduces a refrigerant at or near atmospheric pressure into the unit. The secondary refrigeration loop may be open or closed. The secondary loop includes a secondary heat exchanger for cooling the refrigerant. A primary, closed refrigeration loop, operating at a pressure of not less than 2 atmospheres, includes a forward flow path which comprises a primary refrigerant compressor for producing compressed primary re...
A refrigeration system, comprising: a secondary refrigeration loop connected to a refrigeration load for introducing a secondary loop refrigerant into said refrigeration load, and including secondary heat exchange means for cooling said secondary loop refrigerant; and a primary closed refrigeration loop including a forward flow path comprising refrigerant at a high pressure, expansion means for expanding said primary loop refrigerant to a pressure not less than two atmospheres and within the range of from 40% to 90% of said high pressure so as to cool sa...
