  • Patent number: 10337746
    Abstract: A heat pump has an evaporator for evaporating water as a working liquid so as to produce a working vapor, the evaporation taking place at an evaporation pressure of less than 20 hPa. The working vapor is compressed to a working pressure of at least 25 hPa by a dynamic-type compressor so as to then be liquefied within a liquefier by direct contact with liquefier water. The heat pump is preferably an open system, wherein water present in the environment in the form of ground water, sea water, river water, lake water or brine is evaporated, and wherein water which has been liquefied again is fed to the evaporator, to the soil or to a water treatment plant.

During operation, gas introduced through the tube mixes with the fluid and the combined gas and fluid flow at a high rate with a high degree of turbulence, thereby promoting vigorous mixing and intimate contact between the gas and the fluid, which leads to a more efficient and complete evaporation. Additionally, vapor exiting the submerged gas evaporator is condensed in a condensing unit thus precipitating vapor into a liquid for removal.

  • Patent number: 8672300
    Abstract: A modified carburetor allows the fuel and air input ratio to be adjusted by varying the opening sizes in the carburetor. After the proper air opening size is determined and set, the fuel jet setting can be adjusted for cold starts and/or to fine tune the engine. The air opening setting may remain the same, regardless of engine speed. This allows the engine to create a vacuum of near zero to five inches of mercury or more, depending on the speed of the engine. A small air input opening setting may be used for the engine to create this vacuum. The higher the vacuum created, the better the fuel efficiency. The fuel from the modified carburetor then flows through a heated evaporator chamber that maintains this vacuum. This enhances and completes the evaporation process as the fuel passes through and over metal shavings toward the engine.

  • Patent number: 7897019
    Abstract: Systems and methods for desalting seawater by distillation are disclosed. Warm air is fed into the bottom of a natural draft tower. The warm air passes through seawater in an exchange means to increase the water content of the air. The moisture-laden air then rises and is drawn through a condensing means. The condensing means is cooled by cold water drawn from deep ocean depths. Desalted seawater is collected from the condensing means.

  • Patent number: 7744070
    Abstract: An external gas humidifier for fuel cell transfers recycled high-temperature waste heat produced by the fuel cell to a reactant gas, such as hydrogen or air, which is guided into the external gas humidifier. The heated reactant gas is treated in the external gas humidifier to effectively increase the moisture content of the reactant gas within a shortened time. When the humidified reactant gas enters into the fuel cell, it enables a polymeric membrane in the fuel cell to be well humidified to thereby enhance the power generation efficiency and service life of the fuel cell.

  • Patent number: 7654307
    Abstract: An automotive air conditioning system is disclosed comprising an evaporative cooler in series with the conventional vapor compression system. The evaporative cooler comprises an array of dry channels and a contiguous array of wet channels. The primary air stream to be conditioned by the evaporator of the conventional air conditioning system is preconditioned by the evaporative cooler by lowering its dry bulb temperature without changing its absolute humidity. An evaporator core is supported downstream of the evaporative cooler for receiving the primary air from the dry channels and thereby produces liquid condensate. The system is distinguished by conducting the liquid condensate from the evaporator core to the wicking tank for use in the wet channels of the evaporative cooler.
