  • Patent number: 8721916
    Abstract: The refrigerant composition is a hydrocarbon-based composition that may be used as a refrigerant for air conditioners, refrigerators or the like, and further, which may be used as a detergent for cleaning precision components, such as semiconductor chips, motherboards or the like. The refrigerant composition preferably includes, by volume, between 50% and 65% propylene, between 30% and 45% propane, and between 5% and 10% isobutane. In a preferred embodiment, the refrigerant composition contains about 40% propane, about 55% propylene, and about 5% isobutane (methyl propane) by volume.

  • Publication number: 20130247558
    Abstract: The heat pump with a turbine-driven energy recovery system provides selectively cooled and/or heated air and recovers energy from refrigerant circulation. The heat pump includes a condenser for receiving refrigerant and condensing the refrigerant into a cooled liquid to release thermal energy therefrom. An evaporator receives the cooled liquid refrigerant and boils the refrigerant, the evaporator absorbing thermal energy to boil the refrigerant. A compressor circulates the refrigerant between the condenser and the evaporator, as is conventionally known. At least one turbine is positioned in a refrigerant flow path between the condenser and the evaporator, such that the at least one turbine is driven by the refrigerant circulating therebetween. At least one electrical generator is driven by the at least one turbine, the at least one generator being in electrical communication with the compressor for providing power thereto.

  • Patent number: 8097182
    Abstract: The hydrocarbon refrigerant and detergent composition is a hydrocarbon-based composition, which may be used as a refrigerant for air conditioners, refrigerators or the like, and which may also be used as a detergent for cleaning precision components, such as semiconductor chips, motherboards or the like. The hydrocarbon composition includes about 5.0% ethane, about 60.0% propane, about 5.0% isobutene and about 30.0% butane by volume.

  • Patent number: 7730735
    Abstract: The refrigerant service port valve for air conditioners has a valve body defining a main fluid conduit adapted for insertion into a coolant line using compression fittings at opposite ends of the conduit. A pedestal is mounted on the exterior conduit wall. The pedestal has a bore therethrough forming a lower service passage that enters the main fluid conduit, and an internally threaded blind bore parallel to the lower service passage. A slider is mounted on the pedestal, the slider having a male quick connect fitting defining an upper service passage. The upper service passage may be aligned with the lower service passage in an open position to service the system, or the slider may be moved to align the upper service passage with the blind bore to access a setscrew, which is raised partially into the upper service passage to lock the valve in a closed position.

  • Publication number: 20080257332
    Abstract: The charcoal igniter provides for the pre-ignition of charcoal, prior to placement of the charcoal within a barbecue or grill. The charcoal igniter includes a charcoal receptacle having at least one sidewall, a lower wall and an open upper end. The lower wall has an opening formed therethrough and the charcoal receptacle defines a charcoal-receiving chamber therein. A support is mounted on a gas cylinder, adjacent the nozzle thereof. When the charcoal receptacle is mounted on the support, the nozzle projects through the opening formed through the lower wall. Charcoal is then received within the charcoal-receiving chamber and gas flowing through the nozzle may be ignited. Once the charcoal is ignited, the receptacle may be lifted off the support for dispensing of the ignited charcoal into the barbecue of grill.
