Abstract: A heat pump heating and cooling system uses heat exchange coils which are located vertically in the ground. A double evaporator is used as a condenser in the heating cycle, and a single evaporator is used in the cooling cycle. The device sub-cools the liquid refrigerant during the cooling cycle, and super heats the refrigerant in the heating cycle, increasing the efficiency over prior art heat pump systems. No receiver for excess refrigerant is required, and problems associated with liquid refrigerant settling in the vertical ground coils are eliminated.

Abstract: A single motor drives both oil and refrigerant pumps in a refrigeration chiller, the motor and oil pump being disposed in the chiller's oil supply tank and the refrigerant pump being disposed exterior thereof. The refrigerant pump pumps liquid refrigerant to the chiller's compressor section so as to cool the motor by which the compressor is driven while the oil pump pumps oil to chiller locations that require lubrication when the chiller is in operation.

Abstract: A portable, potable-water generator for producing high-purity liquid water by condensation of dew from ambient air is described. The generator employs filtration subsystems to remove particulates and aerosols from the incoming air. An enclosed heat absorber cools the filtered air below its dew point and collects droplets of condensate into a closed system. The collected liquid dew is further continually treated in a bacteriostat loop to destroy adventitious living organisms and to filter out undesirable and dangerous contaminants. All the subsystems are failsafe-interlocked to disable the generator immediately and prevent delivery of water if any one of them stops functioning within predetermined safe limits. Hybrid embodiments of the water generator attached to or integrated with refrigeration-type appliances such as water coolers, refrigerators, freezers, icemakers and air-conditioners are illustrated.

Abstract: A beverage chilling and insulating device comprising an insulated sleeve for accepting a beverage container such as a beer or soda can. The insulated sleeve is secured at a bottom end to an insulated hollow base which defines a chilling chamber, the chilling chamber in communication with the sleeveway. A cartridge receptacle hole is located upon the insulated hollow base and extends inward into the insulated hollow base to form a cylindrical cartridge chamber. A needle valve protrudes from the cartridge chamber into the chilling chamber. A pressurized refrigerant cartridge which contains a volume of pressurized refrigerant such as freon or liquid nitrogen is inserted into the cartridge chamber until the needle valve punctures the cartridge, allowing the pressurized refrigerant contents to escape from the cartridge, through the needle valve into the chilling chamber and sleeveway.

The support extends downward within the flexible membrane supporting the article therein and allowing thermal contact between the article and chilling liquid via the flexible membrane. The support is radially collapsible or flexible to facilitate improved thermal contact between the article and chilling liquid via the flexible membrane.

Abstract: An air conditioner operating on a compressor-condenser-evaporator circuit utilizes water cooled by air flowing over an evaporative medium through which the water flows to cool a condenser coil located in a continuous serpentine channel in a sump member located at the lower side of the air conditioner unit. The condenser coils include offset intertwined upright coils that provide a large heat exchange surface with water flowing in the channel to a pump intake region of the sump. A pump is provided to supply the evaporative medium with water from the pump intake region of the sump for continuous circulation through the evaporative medium and the sump channel. A water distributor system supplies water uniformly to the top area of the evaporative medium by creating a film of water that is evenly distributed across the top of the evaporative medium.

Abstract: A bi-directional filter/drier having a flat header welded to a casing with a desiccant canister disposed in the casing. The header has a dedicated low side pressure inlet port formed in the flat which communicates through a pair of oppositely disposed check valves in a cross passage with two separate bi-directional inlet/outlet ports into which low side pressure flow is permitted to by-pass the desiccant to the bi-directional ports. Individual passages, each with a stiffer check valve are provided between the bi-directional ports for permitting high side pressure to flow in either port into the desiccant. A stand pip through the desiccant is connected to an interior port in the header and communicates with a dedicated outlet port in header exterior.
