Abstract: An improved system for recovering and charging refrigerant of a refrigeration system. The system includes a series arrangement of two gas compressors that boost the pressure of the recovered refrigerant to a high enough level for storage in a DOT-3AA type cylinder. The recovered refrigerant is not condensed to the liquid state during recovery, nor is the cylinder chilled. The second high-pressure compressor includes a free-floating piston within a cylinder. The piston is hydraulically actuated. The system includes microprocessor control. The system is well suited for recovery of refrigerants such as R-13, R-23, R-503, and SUVA-95.

Abstract: An improved reversible cycle heat pump system incorporating powered subcooling to increase heating capacity by over 50 percent over conventional heat pump technology without imposing a performance penalty; wherein over 21 percent is attributable to evaporator capacity gained by subcooling, over 21 percent is attributable to recovery and utilization of sensible heat energy removed as a by-product of subcooling, and over 8 percent is attributable to recovery and utilization of sensible heat energy resulting from the conversion of electric energy to mechanical work, heat of compression, and mechanical heat of friction. The powered subcooling improvement is also easily installed as original equipment, or retrofitted to existing heat pump systems.

Abstract: The present invention relates to a rupture disk fragment collection trap for minimizing the loss of refrigerant from a mechanical refrigeration system. A mechanical refrigeration system generally includes a storage vessel for the storage of a refrigerant, which to comply with applicable safety codes requires a pressure relief unit for venting an over-pressurized storage vessel. The pressure relief unit includes a fragmentary carbon rupture disk that provides a mechanical seal to contain the refrigerant, prevent the infiltration of contaminants into the refrigeration system, and rupture to relieve the over-pressurized state of the storage vessel. A mechanical re-seating type pressure relief valve is positioned downstream from the carbon rupture disk to control the flow of refrigerant into the atmosphere. The valve and the rupture disk are connected in fluid communication by a sealed passageway containing a rupture disk fragment collection trap. The trap prevents fragments in the passageway following rupture disk breakage from interfering with the operation of the pressure relief valve. After the pressure in the passageway has dropped below a predetermined value the pressure relief valve closes to prevent any further escape of refrigerant into the atmosphere.

Abstract: The present invention relates to a fluid containment system for minimizing the loss of refrigerant fluid from a refrigerant evaporator. The mechanical refrigeration system includes an evaporator for absorbing energy from the cooling media. The evaporator includes a pressurized shell, which to comply with applicable safety codes requires a pressure relief system for relieving an over-pressure condition. A sealed over-pressure containment vessel is connected in fluid communication with the evaporator. The containment vessel receives liquid refrigerant from the evaporator in order to reduce the pressure in the evaporator, and the flow of refrigerant fluid from the evaporator to the containment vessel is controlled by a pressure differential therebetween. After the over-pressure condition in the evaporator has been corrected the liquid refrigerant in the containment vessel can be returned to the evaporator. The containment vessel while receiving liquid refrigerant from the evaporator allows for the reduction of pressure in the evaporator and acts to help prevent the discharge of refrigerant into the atmosphere.

Abstract: A portable apparatus for recovering high-pressure CFC refrigerants in vapor form includes a removable tank for receiving and storing the liquefied refrigerant to be recovered and two refrigeration circuits. The first refrigerant circuit processes the refrigerant to be recovered and includes a compressor and a condenser. The removable tank acts as the evaporator of the first refrigeration circuit. The second refrigeration circuit is included to cool both the condenser of the first refrigeration circuit and the removable tank. This second refrigeration circuit includes a compressor, a condenser and an evaporator, and contains a second refrigerant physically isolated from the refrigerant to be recovered. Both the condenser of the first refrigeration circuit and the evaporator of the second refrigeration circuit are preferably coil shaped, with the condenser coil preferably coaxially arranged within the evaporator coil. The condensing coil/evaporator coil arrangement substantially surrounds the removable tank to assist in cooling that element. The compressor of the first refrigeration circuit is preferably capable of compressing vapor refrigerants to a pressure of at least about 300 psi. Wheels and handles to assist in moving the liquid refrigerant recovery apparatus are also provided.
