Abstract

A glycol chiller comprising an elongate vertical sheet metal tank with front and rear walls, laterally spaced vertical end walls, vertically spaced top and bottom walls and a horizontal intermediate wall spaced between the top and bottom walls and defining a lower glycol chiller chamber and an upper glycol reservoir within the tank filler opening in the top wall, a flow through port in the intermediate wall conducting glycol from the reservoir into the chamber, a plurality of spaced apart partitions in the chiller chamber defining an elongate zig zag glycol flow passage with upstream and downstream ends within the chamber, glycol inlet and outlet fittings communicating with opposite ends of the flow passage and projecting from the tank to connect with glycol return and delivery lines extending from a related heat exchanging device; a motor driven pump downstream from the inlet fitting and operating to continuously recirculate glycol through the flow passage and the selected heat exchange device; an electric powered freon charged refrigeration machine including an elongate zig zag evaporator coil extending longitudinally and centrally through the passage; and, a thermal insulating jacket structure about he exterior of the tank.
