Abstract: An air conditioning device has a heat source unit and a utilization unit connected via a refrigerant connection pipe to form a refrigerant circuit, and has a cooler, a secondary receiver, and a separation membrane device. The cooler cools at least a portion of the refrigerant that flows through the liquid-side refrigerant circuit as the compressor is operated and the refrigerant in the refrigerant circuit is recirculated. The secondary receiver separates the refrigerant cooled by the cooler into a liquid refrigerant and a gas refrigerant that includes non-condensable gas. The separation membrane device has a separation membrane for separating the non-condensable gas from the gas refrigerant obtained by gas-liquid separation, and discharges the non-condensable gas thus separated to the outside of the refrigerant circuit.

Abstract: The improved refrigeration system of the present invention includes an accumulator with a diffuser pipe extending downwardly into the upper end of a vapor refrigerant tank, the diffuser pipe extending from an evaporator and discharging vapor refrigerant therefrom into the tank. The diffuser pipe includes a lower end located within the interior of the tank which is expanded in diameter relative to the upper end, thereby reducing the velocity of fluid flowing through the pipe and entering the accumulator tank. A diffusion plate is mounted in the lower end of the diffuser pipe, to further diffuse fluid flowing therethrough.

Abstract: An auxiliary purge unit to be retrofitted to the existing purge unit of a low pressure refrigeration system includes a double-walled condenser portion, a pneumatic pressure chamber and a discharged-refrigerant tank. The double-walled condenser portion includes inner and outer walls with a chilled condensing coil disposed between the two walls, a stand pipe to create a reservoir of condensed refrigerant between the stand pipe and the inner wall, and an exhaust port for exhausting non-condensibles from the system. The pneumatic pressure chamber pressurizes the gas to be purged from the refrigeration system and delivers it to the chilled condensing coil. The discharged-refrigerant tank includes a float valve to prevent fluids from exiting the tank unless the valve is in the open position, and allows the elevated pressure of the system to be maintained. In operation, the gas to be purged from the system is pressurized, directed through the chilled condensing coil, and bubbled through the reservoir of liquid refrigerant.

Abstract: An improved process for separating and removing non-condensible gaseous contaminants (e.g., nitrogen, oxygen and the like) from a conventional halocarbon vapor compression refrigeration system by withdrawing a vapor stream above liquified refrigerant exiting the condenser on the high pressure side of the expansion valve and then processing this vapor by use of a second compression step, followed by condensation into a receiver. The liquid halocarbon from the receiver is returned to the evaporator while the vapor phase is sent to a semipermeable membrane separation unit. The halocarbon enriched effluent from the semipermeable membrane unit is recycled to the inlet side of the second compressor while the non-condensible contaminant enriched stream is vented from the refrigeration system. Such a high pressure purge loop is useful in selectively removing non-condensible gaseous with minimum halocarbon refrigerant loss.

Abstract: A refrigeration system is disclosed having a purge system with means for monitoring operation of the purge system and for taking corrective action in response to excessive purge system operation. Preferably, the monitoring means is a microcomputer control system for monitoring purge pump operation to determine if the purge pump has operated continuously for a period of time greater than a predetermined amount of time. If the purge pump has operated continuously for a period of time greater than the predetermined amount of time, then the microcomputer control system overrides normal purge pump operation and maintains the purge pump inoperative for a selected time period before attempting to resume normal operation. The microcomputer control system counts the number of consecutive times that normal purge pump operation is overridden and totally disables the purge system if the number of consecutive overrides exceeds a preselected number.

Abstract: A purge apparatus for removing foreign non-condensable gases from a refrigeration system including a closed vessel adapted to receive the foreign gases together with a portion of the refrigerant from the high pressure region of the system. The vessel is cooled to condense the refrigerant, and a float actuated electrical switch is provided within the vessel to open a first valve for discharging the condensed refrigerant upon the refrigerant reaching a predetermined level, and a second valve for venting the non-condensable gases to the atmosphere upon a drop in the refrigerant level. The discharged condensed refrigerant is utilized to cool the vessel by evaporating the same in an area about the outer walls of the vessel, and then returned to the low pressure region of the system.
