  • Patent number: 10668536
    Abstract: First subareas of a layer of powder applied on a substrate are heated locally with a process beam so as to heated, but not yet interconnect the grains of the powder in the first subareas. A temperature profile of the applied layer is evaluated proximate to the first subarea as a function of the distance from the respective first subarea and/or the time. The local thermal conductivity and/or local diffusivity are determined for the respective first subarea based on the temperature profile. Second subareas of the applied layer which at least partially overlap the first subareas are then heated locally with the process beam so as to interconnect the grains of the powder in the second subareas. A process variable of the process beam influencing heating of the second subareas is determined based on the local thermal conductivity or diffusivity previously determined for the at least partially overlapping first subarea.

  • Patent number: 10383175
    Abstract: An apparatus and method for melting snow and/or ice on a vehicle comprises a precipitation sensor, a surface temperature sensor, an ambient temperature sensor, a heater, and a programmable controller. The programmable controller comprises a memory unit to store a cut off surface temperature Tc, and a set of program modules. The programmable controller further comprises a processor to execute the set of program modules. A heater control module, executed by the processor, is configured to deactivate a heater based on a surface temperature being greater than the cut off surface temperature. Further, heater control module is configured to activate the heater based on an ambient temperature being lower than freezing point of water and precipitation being present outside the vehicle, thereby melting snow and/or ice on the vehicle. The snow melts off because of heat generated by the heater upon activation.

  • Publication number: 20140020413
    Abstract: The present invention relates to a heat exchanger module with thermal management containing a titano-alumino-phosphate as adsorber, which displays a high hydrothermal stability and already desorbs the adsorbed water again under the action of low heat. By targeted action of temperature, the adsorbed water is condensed out, whereby heat energy is released. By means of the action of low heat, the condensed water can be adsorbed again as cold vapour on the adsorber, whereby heat energy is released. The heat exchanger module can be used to heat objects, appliances or rooms on the basis of the adsorption energy being released during the adsorption, as this is discharged and used further. In addition to heating, the cooling of rooms, objects and appliances is also possible, as the area surrounding the heat exchanger module is cooled due to a fall in the temperature in the heat exchanger module.

    Abstract: A split solid adsorption cooling system is disclosed. The split solid adsorption cooling system includes a first adsorption unit, a second adsorption unit, and a shell-and-tube heat exchanger. The first and the second adsorption units are connected to each other via a first pipeline and a second pipeline of the shell-and-tube heat exchanger. While adsorption and desorption take place alternately in the first and the second adsorption units, the temperature of the first and the second pipelines is lowered, thereby decreasing the temperature of water flowing in the shell-and-tube heat exchanger. In addition, the manufacturing costs of the split solid adsorption cooling system can be lowered because the shell-and-tube heat exchanger need not be operated in a vacuum environment. Furthermore, as the shell-and-tube heat exchanger is separate from the first and the second adsorption units, the overall system volume is reduced.

The HT phenomenon is a reversible sorption of the fluid G by a liquid or solid sorbent. The endothermic phase of the LT phenomenon takes place in a reactor thermally isolated from the ambient environment.

  • Patent number: 7578143
    Abstract: A thermal compressive device provides energy-efficient heating or cooling by exploiting heat regeneration in a sorption system. The device comprises an array of generator modules (7) arranged in two banks (10, 11) to either side of a heating zone (13). Heat carrier fluid is driven past the modules in a reversible direction. During one phase, generators in the first bank (10) are cooled and therefore in various stages of sorbate re-adsorption. Sorbate in associated evaporator region(s) (26) will boil, enabling cooling of surrounding fluid (33). Generators (7) in the other bank (11) will be in various stages of desorption. Sorbate in associated condenser region(s) (21) will condense, enabling heating of its environment. During the other phase, each generator (7) switches function, but cooling remains at evaporator regions (26) and heating at condenser regions (21). Each module may be a self-contained unit comprising generator (7), condenser (21) and evaporator (26) sections.

  • Patent number: 7568355
    Abstract: Disclosed is a humidity control device which is provided with an adsorptive element (81, 82) having a humidity control passageway (85) capable of adsorption of moisture from a first air stream and of release of moisture to a second air stream, and which provides an air stream, the humidity of which is conditioned in the adsorptive element (81, 82), to an indoor space. In the humidity control device, the adsorptive element (81, 82) is provided with an auxiliary passageway (86) through which a heating fluid flows when the adsorptive element (81, 82) is regenerated by releasing moisture to a second air stream from the humidity control passageway (85). As a result, during regeneration of the adsorptive element (81, 82) by releasing moisture to a second air stream, the amount of release moisture is increased, thereby enhancing the device performance.

  • Patent number: 7490482
    Abstract: A two-liquid absorption refrigerator or space cooler of the cyclic type uses a spiral shaped Bourdon Tube as the refrigerant gas generator, with the lower end of the spiral disposed at a heat source. The generator may also function as the absorber vessel, thus greatly simplifying the operation of the device. In use, when ammonia depletion during the cooling cycle allows the generator to heat, it moves its lower end to a position removed from the heat source and begins to cool, thus allowing a charging cycle to replenish ammonia into the absorption liquid (usually water) in the generator. The device may thus function with only one moving part and without electricity, and further without control over the heating source.

  • Publication number: 20080209920
    Abstract: A method is provided of operating an adsorption refrigeration system. The system comprises a primary adsorption pump which is arranged in communication with a primary chamber containing coolant, a secondary adsorption pump and a high fluid impedance conduit which places the secondary adsorption pump and primary chamber into communication. The method comprises saturating the primary and secondary adsorption pumps with coolant whilst each pump is at its respective operational temperature. The pumps are then heated above their operational temperatures to desorb the coolant such that the coolant pressure in the primary chamber and the secondary adsorption pump substantially equalises through the conduit whilst the primary chamber is cooled. The secondary adsorption pump is then cooled causing coolant gas to be adsorbed and therefore a reduction in temperature and pressure of the coolant in the primary chamber is effected.

    Abstract: A thermal storage and transfer system includes a cooling system and method using ice or other frozen material with heat pipes to produce a cool airstream. Preferably, the ice is disposed in a container with the condensers and evaporators of the heat pipes respectively inside and outside the container. A fan blows air across the evaporator sections through a duct to circulate within an enclosed airspace to be cooled. A separate refrigeration system which may be used to independently cool the airspace also freezes water or another liquid to produce the ice or other frozen material in the container. The cooling system is broadly applicable, including use on motor vehicles to provide cooling for several hours when the vehicle engine is off. A heating system includes an adsorbent heat exchanger for extracting heat from exhaust gases of an engine and heating an enclosed airspace.
