  • Patent number: 9651310
    Abstract: The present invention relates to a heat recovery system, of a part of the energy spent in the preparation of waste water, e.g. water from baths or kitchens, energy that is usually lost when the water is drained into the sewer. This energy can be recovered and reused to heat water that is readily used, for example in the shower, or can be stored in a water heater. This system is designed in such a way that, together with any tub or shower base, constitutes a heat recovery shower base or a heat recovery bath, for example. The energy recovery system is composed, preferably, by a coil generally made of copper inside a PVC pipe that has at one end a throttle plate also made of PVC, a filter for the protection of the system against impurities, turbulence fins, and an external casing. The system has a compact structure which benefits its rapid adaptation.

  • Patent number: 8534346
    Abstract: A modular, water-to-air heat exchanger with flexible tubes is adjustable in length to conform to different size cooling coils and thus provides an inexpensive, retro-fittable run-around heat recovery for pre-existing air handling systems. The heat exchanger comprises multiple heat exchange tubes formed of flexible material in a shape that permits them to be lengthened or shortened by simply moving the headers toward or away from each other. Preferably, the tubes are formed of a flexible, non-resilient material such as copper, and are shaped in a serpentine or helical manner. In this way, the tubes can be drawn out to elongate the heat exchanger or compressed to shorten it, depending on the dimension of the cooling coil in the air handler. One convenient way to control the length of the flexible tubes is to support the headers on one or more adjustment bars, each having a threaded adjustment mechanism.

    Abstract: A system and method of recovering some of the latent heat of vaporization in a system having a heated environment that adds heat to liquid material and converts the liquid material into gaseous material. The latent heat of vaporization is partially recovered using a unique heat exchanger. The heat exchanger preheats the liquid material entering the heated environment with heat energy from the gaseous material exiting the heated environment. The heat exchanger has a gas flow path. A volume of a gas medium fills the gas flow path. A pump causes the gas medium to flow through the gas flow path at a predetermined mass flow rate. The gas medium and its flow rate are selected to ensure that the specific heat of the gas medium surpasses that of the gaseous material exiting the heated environment.

When the top plate is fastened and sealed to the lower plate, the flow of the incoming cold water is contained within the confines of the serpentine lower plate of the heat exchanger. Heat is transferred from the grey waste water falling onto the top plate to preheat the incoming cold water flowing underneath the top plate in the serpentine conduit chamber of the lower plate in contact with a bottom surface of the top plate. The cold water is thereby preheated and used as a substitute for the incoming cold water that would be normally plumbed to the discharge shower head.

  • Patent number: 7539601
    Abstract: A refrigeration based air handling system design process for significant energy and cost savings in cleanroom and other applications requiring large air change rates is presented. The process utilizes a by pass around the air conditioning system, the ratio of bypass to air conditioning flow being such that minimal or no reheat of the air is required for applications having relative humidity (RH) control requirements and with RH control being achieved via cooling. If dehumidification is achieved by adsorptive processes, then the by pass ratio is varied so as to minimize cooling of the heated dry air. In other non relative humidity control applications the bypass is varied to minimize the air conditioning flow, thereby decreasing cost, but by using optimum cooling coil velocities in a manner such that system energy for airflow is minimized. The energy and cost savings achieved by this process vary between 65% to 15% depending on the Class of the cleanroom and/or on the number of air changes per hour required.

  • Patent number: 7442353
    Abstract: A process by which heat is removed from a reactant fluid to reach the operating temperature of a known pollutant removal method and said heat is recirculated to raise the temperature of the product fluid. The process can be utilized whenever an intermediate step reaction requires a lower reaction temperature than the prior and next steps. The benefits of a heat-recirculating cooler include the ability to use known pollutant removal methods and increased thermal efficiency of the system.

  • Patent number: 7398643
    Abstract: A combined EGR cooler and non-thermal plasma device has first and second fluid passageways which are in heat exchange communication with one another. One or more electrodes are located in the second fluid passageway. The electrodes are connected to a voltage source. When a voltage of sufficient magnitude is applied to the electrodes, a non-thermal plasma is generated in the second fluid passageway. The device can be constructed in the form of a shell-and-tube heat exchanger or a stacked-tube type heat exchanger, wherein the electrodes extend through the heat exchange tubes. Hot exhaust gases preferably flow through the tubes in heat exchange contact with a liquid coolant, thereby cooling the exhaust gases. The electrodes generate non-thermal plasma inside the tubes, converting at least a portion of the NO in the exhaust to NO2, which reacts with soot in the exhaust gases to generate CO2 and N2, thereby cleaning the exhaust gases.

  • Patent number: 7360580
    Abstract: A heat exchanger is mounted external to a section of flue pipe or is an integral part of a section of flue pipe. The heat exchanger preheats a domestic hot water supply and boosts the return water temperature prior to reentry to the furnace coil. The heat exchanger reduces fuel use, pollution and wear of the furnace and burner. A typical heat exchanger installation includes an oil or gas burner located on a furnace or boiler having a flue pipe leading to a gaseous outlet, such as a masonry chimney. A short vertical flue section leads to a draft-regulating damper. The flue heat exchanger may be a coil of tubing wrapped around flue section, such that the tubing picks up heat from the heated flue gasses. Preheated water exits from the heat exchanger.

  • Patent number: 7316261
    Abstract: A heat exchanging system of a ventilating device includes: a heat exchanging housing communicating with an outdoor air passage and an indoor air passage; a rotational shaft rotatably supported at one side of the case of a ventilating device; and a heat exchanging elements mounted at an outer circumferential surface of the rotational shaft at regular intervals, and performing a heat-exchanging operation of outdoor air and indoor air while being rotated by a wind force of outdoor air passing the outdoor air passage and a blow force of indoor air passing the indoor air passage. Thus, any additional driving unit is not necessary to rotate the heat exchanging system, so that a fabrication cost can be reduced, the overall size of the ventilating device can be reduced, and a noise and vibration can be reduced.

  • Patent number: 7101507
    Abstract: Aerobic and anaerobic contamination is removed from a slurry by a sterilizing process and apparatus (10). A slurry piping circuit (26, 28, 30, 32, 34) interconnects a supply tank (12), three serial heat exchangers (16, 18, 20) and a storage tank (14). The circuit and storage tank are sanitized by flushing with mist of hydrogen peroxide (44) and nitrogen (50). One heat exchanger (16) transfers heat from the sterilized slurry to the unsterilized slurry. A closed hot water piping circuit (60, 62, 64) interconnects a hot water boiler (22) and the other two heat exchangers (18, 20). The slurry is sterilized in an insulated manifold (24) interconnecting the other two heat exchangers (18, 20). Slurry is pumped through the piping and heated by hot water in the manifold to kill the bacteria, and is covered by a layer of nitrogen (54) in the storage tank (14).
