Recirculation Patents (Class 165/108)
  • Patent number: 11662147
    Abstract: A dual fluid heat exchange system is presented that provides a stable output temperature for a heated fluid while minimizing the output temperature of a cooled fluid. The heated and cooled fluids are brought into thermal contact with each other within a tank. The output temperature of the warmed fluid is maintained at a stable temperature by a re-circulation loop that connects directly to the mid portion of the tank such that the re-circulated fluid flow primarily warms only a re-circulation section of the tank. The other, lower flow rate, section of the tank may be positioned so that it has a cooler temperature and thus serves to increase the efficiency of the heat exchange by extracting extra heat energy out of the cooled fluid before it leaves the tank. Alternatively, the low flow rate section of the tank may be warmer than the re-circulated section, and thus allow the re-circulated section to be cooler than the output temperature of the warmed fluid.

  • Patent number: 10876276
    Abstract: An atmospheric water generation system with high efficiency is based on a counter flowing heat exchanger including multiple cold channels, each cold channel surrounded by multiple hot channels. The hot and warm gases flow in opposite directions, allowing the cool dry air to contribute to cooling the warm humid air to the dew point. Thermoelectric or passive cooling of the warm humid air, and hydrophobic surfaces in a cyclone structure also contribute in increasing the efficiency of the water generation system.

  • Patent number: 10655581
    Abstract: A returnless fuel supply system applicable to an LPG vehicle is provided. The system supplies LPG fuel from an LPG bombe to an engine at a predetermined pressure or greater and prevents the generation of vapor in the LPG fuel, thereby eliminating a need to return a portion of the LPG fuel supplied to the engine to the LPG bombe. Through the application of the returnless fuel supply system that does not return the high temperature fuel to the LPG bombe, the cause of the internal pressure increase in the LPG bombe is eliminated, and thus efficient refueling of LPG bombe with LPG fuel is achieved.

It has a hot side for grey water, and a cold side for fresh water under pressure. The heat recovery apparatus extracts heat from grey water to pre-heat water for a water heater. The fresh water is carried in passes in series, each pass being immersed in a grey water sump in a plastic pipe. The water level in the sump is high enough to immerse the dominant portion of the fresh water pass in grey water. Both ends of the fresh water coil are carried out through the same upper end pipe closure, without a penetration in the pipe wall. The entire assembly may be enclosed in a unitary external housing with easily accessible connection fittings.

  • Patent number: 10137410
    Abstract: The invention is a method for deacidizing a gaseous effluent comprising acid compounds, such as CO2 and/or H2S, and a device for implementing the method, through contact with a demixing absorbent solution. Regeneration is performed by vapor injection into the liquid guard (202) formed by the regenerated absorbent solution in the bottom of regeneration column (G). The vapor is generated within a reboiler (203) from a fraction of the regenerated absorbent solution withdrawn from the regeneration column. Vapor injection enables convective movement of the liquid for preventing any decantation phenomenon in the bottom of the regeneration column bottom which is harmful to the smooth operation of the deacidizing process.

  • Patent number: 8590603
    Abstract: An aircraft heat exchanger that exchanges heat between fluid, like air, to be warmed and a medium, like a liquid, to be cooled has a first path that encounters the fluid to be warmed and carries the medium at a first temperature. A second path carries the medium at a second temperature adjacent to the first path. An insulation gap is disposed between the first path and the second path so that heat exchange between the first and second path is minimized.

  • Patent number: 8499551
    Abstract: A first heat medium is circulated in a first circulating path (engine cooling circuit) of a heat source (engine) to cool the heat source down by the first heat medium, and exhaust heat from the heat source is absorbed by the first heat medium. A second heat medium is circulated in a second circulating path (exhaust heat recovering circuit) to exchange heat of exhaust air with the second heat medium, and heat of the first heat medium is exchanged with the second heat medium circulating in the second circulation path. The heat of the second medium to which heat is applied due to these heat exchanges is stored in heat storage means (heat storage tank).

  • Patent number: 8011536
    Abstract: A dispenser of cooled or heated liquid which in one embodiment is a server cart for an aircraft. To avoid the need for a pump, the reservoir has a cooling or heating heat exchanger that helically coils around the main reservoir, which cools from the top down or heats from the bottom up, forming a counter current. The reservoir is connected to at least two conduits, one near the cooler top of the reservoir and one near the relatively warmer bottom of the reservoir. The two conduits connect to one another at a distance from the reservoir forming a dispensing passage, thereby allowing fluid to constantly circulate through the dispensing passage due to difference in the specific gravity in the fluid caused by the temperature difference. The elimination of the pump device is especially desirable for weight sensitive environments such as an aircraft.
