    Abstract: Systems and methods are disclosed for processing hot, humid air resulting from an industrial process, such as paper production. These systems and methods allow a large amount of water to be recovered from the air and the plume emitted into the environment to be reduced, all with reasonable energy consumption. The exhaust stream of air is passed through two heat exchangers, which cool the exhaust air by heating respective streams of water. The heated streams of water are routed to and cooled by an absorption cooler before being returned as input to the heat exchangers. Some embodiments may also include a scrubber, which allows direct air-water contact, positioned between the two heat exchangers. The scrubber also aids removal of pollutants. Some embodiments may mix heated outside air with the exhaust stream of air prior to discharge in order to reduce the emitted plume.

  • Patent number: 8534067
    Abstract: Disclosed is an energy retriever system and methods for absorbing energy and using that energy elsewhere or converting it to other useful forms of energy or work. The energy retriever system consists of a series of components interconnected by a plurality of conduits containing a fluid. Working as a self-contained thermodynamic system, the energy retriever system allows the fluid to circulate through all of these elements. Heat added to the energy capture subsystem heats the fluid. The fluid becomes more pressurized and moves into the expansion cycle subsystem. The energy extraction subsystem transforms the thermal energy of the fluid into work, kinetic energy or thermal energy. The reservoir subsystem compresses the fluid and reintroduces it into the energy capture subsystem. One-way valves are used throughout the system to keep the flow of the fluid in one direction and separate sections of the system that contain different pressures.

A low temperature heat source is used as a heating working medium to heat in a regenerator by heat exchange the absorption liquid working fluid from the absorber and consisting of a salt absorbent and ammonia or carbon dioxide as an absorbed agent to form the absorbent and the superheated high pressure absorbed agent. The superheated and vaporized absorbed agent enters into a turbine to provide energy and generate power via turbine expansion step. After heat release, the resultant low pressure absorbed agent is discharged from the turbine and returns to the absorption step and contacts with the absorbent from the regeneration step to form the absorption liquid which can enter into the next thermodynamic cycle process.

  • Publication number: 20110225991
    Abstract: The absorption chiller-heater apparatus of present invention utilizes a portion of direct heat, used to heat water, for providing the refrigeration effect. The external heat input required for providing refrigeration is minimal; hence, the efficiency of the apparatus is increased by 30-40% over the conventional systems. Further, as the quantum of the external heat source required for a new cycle is reduced, the size of the high temperature generator required, is smaller, which results in lower capital costs. The apparatus provides chilled water which can be used for various industrial purposes. The absorption chiller-heater reduces CO2 emissions and utilizes a single arrangement to produce both heating and refrigeration effect. Thus, additional electrical and heat input or separate components are not required.

  • Patent number: 7997077
    Abstract: Disclosed is an energy retriever system and methods for absorbing energy and using that energy elsewhere or converting it to other useful forms of energy or work. The energy retriever system consists of a series of components interconnected by a plurality of conduits containing a fluid. Working as a self-contained thermodynamic system, the energy retriever system allows the fluid to circulate through all of these elements. Heat added to the energy capture subsystem heats the fluid. The fluid becomes more pressurized and moves into the expansion cycle subsystem. The energy extraction subsystem transforms the thermal energy of the fluid into work, kinetic energy or thermal energy. The reservoir subsystem compresses the fluid and reintroduces it into the energy capture subsystem. One-way valves are used throughout the system to keep the flow of the fluid in one direction and separate sections of the system that contain different pressures.

  • Publication number: 20110100036
    Abstract: A solar-powered adsorption-desorption refrigeration and air conditioning system that uses nanostructural materials such as aerogels, zeolites, and sol gels as the adsorptive media. Refrigerant molecules are adsorbed on the high surface area of the nanostructural material while the material is at a relatively low temperature, perhaps at night. During daylight hours, when the nanostructural materials is heated by the sun, the refrigerant are thermally desorbed from the surface of the aerogel, thereby creating a pressurized gas phase in the vessel that contains the aerogel. This solar-driven pressurization forces the heated gaseous refrigerant through a condenser, followed by an expansion valve. In the condenser, heat is removed from the refrigerant, first by circulating air or water. Eventually, the cooled gaseous refrigerant expands isenthalpically through a throttle valve into an evaporator, in a fashion similar to that in more conventional vapor recompression systems.
