Abstract: There is disclosed a refrigeration system for a soft drink plant which refrigeration system provides cooling for cooler/carbonators used in the manufacturing of soft drink and which utilizes any access compressor capacity to precool water being used in the manufacture of soft drinks while assuring priority and adequate cooling capacity for the cooler/carbonators.

Abstract: A cascade heat exchange system in which the heat given off in condensing a superheated vaporized refrigerant is used to vaporize carbon dioxide and to add sensible heat to a water system. The superheated discharge vapor of a refrigeration system is pumped into the shell side of a heat exchange vessel, where evaporative tube bundles absorb heat from the refrigerant. In one tube bundle, liquid carbon dioxide flowing through the tubes is vaporized. Another tube bundle receiving heat from the refrigerant is used to heat water for industrial use. The vaporized refrigerant leaving the heat exchange vessel shell having become desuperheated and de-oiled since giving off heat to the tube bundles is then condensed for continued use in the refrigeration cycle.

Abstract: An injector cooler control system which controls the flow of refrigerant from a common receiver that ties a common refrigeration plant to more than one injector cooler systems. The control system limits the amount of liquid refrigerant entering a cooler surge tank by limiting the amount of liquid refrigerant passing from the receiver through an injector valve, thus preventing liquid carryover to the compressor of a common refrigeration plant.
