ABSTRACT:
A cooling system which is modular and capable of maintaining a variety of pre-selected temperatures for a plurality of liquids being dispensed and/or a plurality of spaces being air conditioned. A single refrigerator unit has a chilled glycol distribution line connected thereto and through which the chilled glycol is pumped. One or more cooler modules are tapped into the glycol distribution line at points wherever desired. The modules contain a low boiling refrigerant, a fluid tube carrying a relatively warm fluid (liquid or air), a cooling tube connected to the distribution line run and a flow control valve responsive to pressure changes in the module for permitting flow of chilled glycol thereinto and being adjustable to achieve the desired temperature of the fluid within the fluid tube.
