Abstract: A chilled beverage dispenser has a “holeless” bowl and uses a cradle evaporator to achieve cooling of the beverage. In one exemplary embodiment, the cradle evaporator comprises three panels—a bottom panel and two side panels, the side panels being bolted or similarly fastened to the edges of the bottom panel in a substantially perpendicular orientation relative to the bottom panel. The bottom and side panels each define a continuous and sinuous channel, which carries a cooling medium. The dispenser bowl preferably is constructed of a thin-walled plastic, such that when the dispenser bowl is received in the cradle evaporator, heat transfer is achieved through the bottom wall and portions of the side walls of the bowl.

Abstract: A flash tank configuration for an economizer is provided that is inexpensive and simple to construct, reliable to operate, and efficient for use in an economizer compression refrigeration system. The configuration includes an upper baffle and a lower baffle configured and arranged within the flash tank so as to separate the liquid and gas phases of intermediate pressure refrigerant, and to convey each phase to other components in the refrigeration systems. The flash tank has a generally cylindrical shape, and is dimensioned so as to provide adequate internal volume for expansion of refrigerant to a desired pressure, separation of the resulting refrigerant gas and refrigerant liquid phases, and temporary storage of the refrigerant phases before conveying the liquid phase to the main refrigerant line between the condenser and the evaporator, and returning the gas phase to the compressor. Additionally, methods are provided for using the flash tank to separate refrigerant phases.

Abstract: The surroundings heat exchanger envelops an enclosure's insulation so that it exchanges part of its heat load directly through the enclosure, instead of indirectly with the surroundings which would then exchange an equal amount of heat with the enclosure. This reduces the temperature differentials required to drive heat a transfer because little heat remains to be transferred by the indirect path.

The coil is bonded to the shell, and a heat transmitting layer between evaporator coil turns is formed using a heat conducting adhesive material having metal granules dispersed in a resin base.

Abstract: The present invention is a mechanical cooling system, for use with thermal analysis instruments such as differential scanning calorimeters, which interposes a gaseous heat transfer path between the heat exchanger or evaporator cooling the differential scanning calorimeter cell and the differential scanning calorimeter cell. This configuration improves the performance of the thermal analysis system by reducing noise in the heat flow signal otherwise resulting from evaporation of the refrigerant in the heat exchanger. The mechanical cooling system is attached to the thermal analysis instrument by an arrangement providing for minimum direct physical contact between the mechanical cooling system and the thermal analysis instrument.
