  • Patent number: 6912858
    Abstract: A cryogenic liquid stream from a storage tank to be pumped is passed through the heat exchanger located within a phase separator vented to atmosphere and a subsidiary cryogenic stream is divided out of the cryogenic liquid stream and is diverted to the phase separator prior to a pump. Low pressure maintained within the phase separator causes the subsidiary cryogenic stream to boil off and form a liquid fraction that covers the heat exchanger. The liquid fraction, which is at a sufficiently low temperature, subcools the cryogenic stream passing through the heat exchanger. Flow of the subsidiary cryogenic stream is suspended when the height of the liquid fraction reaches a predetermined level and is reestablished when the level falls due to boil off. During periods of suspended flow, flow is temporarily reinitiated to prevent the accumulation of warm liquid and vaporized liquid near or at the inlet to the pump.

  • Patent number: 6910346
    Abstract: The device includes a heat pump integrating a refrigerant circuit taking calories from a cold source to transfer them towards a warm source. The device also includes a heat-conducting fluid/air thermal exchanger called external exchanger (30), located in the vehicle engine compartment (34), the heat-conducting fluid being either the refrigerant or a heat-conducting fluid in thermal exchange with the cold source refrigerant. The device also includes means of formation of an air flow, preferably a fan (40), circulating through the external exchanger (30) and called outlet air flow, directed from inside the engine compartment (34) to outside the vehicle. Preferably, the fan (40) shall be able to rotate in a first direction to form an air flow directed from outside the vehicle to inside the engine compartment (34) and called inlet air flow, and in a reverse direction to form the outlet air flow.

  • Patent number: 6907748
    Abstract: Each blow-off valve includes a valve body with a first movable wall defining a portion of the liquid fluid passage therein and a second movable wall defining a portion of the suction fluid passage therein. An actuator interconnects the movable walls for simultaneously moving the walls and opening the fluid passages in response to the electrical leakage-warning signal. In the species of FIGS. 2 and 3, the movable walls are integrally united with the valve body and include frangible sections that are fractured by an explosive squib to separate the movable walls from the body to simultaneously open the liquid and suction fluid passages. In the species of FIG. 5, the movable walls are separate valve elements disposed in a circular bore that opens the passages to the ambient surroundings. The actuator includes a spring, for biasing each of the valve elements out of its respective bore, and a holding device that weakens in response to the electrical leakage-warning signal.

  • Patent number: 6871509
    Abstract: An air conditioning system is disclosed which takes advantage of low ambient temperature conditions so as to activate a refrigerant flow that bypasses the compressor. The activation of the refrigerant flow is achieved by the intelligent control of a pump positioned between the outlet of the condenser and the inlet of an expansion device upstream of the evaporator. The refrigerant flow produced by the pump does not require any particular positioning of the condenser and evaporator components with respect to each other. The evaporator preferably absorbs heat from water circulating in a secondary loop which is used to remove heat from a building by one or more fan coil units.

  • Patent number: 6823686
    Abstract: A pressure equalization method and system is provided for starting a compressor while maintaining the condenser at a high pressure and includes a valve and a bleed port. The compressor has a compressor inlet for receiving a fluid at a first pressure and a compressor outlet for discharging the fluid at a second pressure, and is operable to compress the fluid from the first pressure to the second pressure. The valve is proximate to and in fluid communication with the compressor outlet and is movable to an open position when the compressor is operating to permit the fluid at the second pressure to flow through the valve and is movable to a closed position when the compressor stops operating to prevent backflow of the fluid at the second pressure through the valve toward the compressor inlet. The bleed port is upstream of the valve and in fluid communication with the compressor inlet to equalize the pressure of the fluid contained in the compressor when the compressor stops operating.

  • Patent number: 6820437
    Abstract: An air conditioner includes a direct-current (DC) power supply, a compressor, and a compressor driving device that converts a current supplied from the DC power supply into an alternate-current (AC) for driving the compressor. The DC power supply energizes the driving device through a center conductor and an outer conductor of a shield cable. This structure allows the driving device not to include a capacitor for smoothing a power current, and to suppress surge voltages and electromagnetic-wave radiation, thus providing an air-conditioner including a compact size and light-weighted compressor driving device.
