  • Patent number: 11976603
    Abstract: A method performed by a control unit in connection with a pre-heating process of an aftertreatment system for a combustion engine is provided. The control unit obtains a scheduled start time of the combustion engine. The control unit schedules a pre-heating of the aftertreatment system to be completed before the scheduled start time. The control unit detects a start of the combustion engine at an actual start time. In response to the detected start of the combustion engine, and using the actual and scheduled start times, the control unit determines whether the scheduled pre-heating of the aftertreatment system fulfils one or more success criteria. When the one or more success criteria are fulfilled, the control unit triggers a performance increase of the combustion engine.

  • Patent number: 11821654
    Abstract: The attic hot air recirculation system is mechanical system. The attic hot air recirculation system is configured for use with an HVAC system of a building. The attic hot air recirculation system is energy saving technology. The attic hot air recirculation system captures solar energy from the roof of the building. The attic hot air recirculation system monitors the temperature of the captured solar energy and the temperature of a chamber in the building. The attic hot air recirculation system uses the heat generated from the captured solar energy to heat a chamber in the room. When the temperature difference between the temperature of the captured solar energy and the temperature of a chamber in the building makes it thermodynamically favorable to do so, the attic hot air recirculation system transfers heat from the roof into the chamber.

  • 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.

  • Patent number: 8459044
    Abstract: A thermochemical reactor (1) for a cooling and/or heating includes at least one reagent unit (2) which, using chemical combination, can absorb a gas stream originating from a tank and which, using the reverse chemical reaction, can desorb the gas stream due to a rise in temperature. The reagent unit (2) is disposed in a container (3) that has walls, at least some of which are equipped with diffusers (7) for distributing the gas stream. In addition, the reagent unit (2), which can be heated, is of the type that can expand during absorption of the gas stream and retract during desorption of the gas stream. Moreover, at least some of the walls are mobile walls, which can accompany the longitudinal movement of the reagent unit (2), to enable successive deformation phenomena.

  • Patent number: 8302425
    Abstract: The invention discloses a regenerative adsorption system (50). The system includes at least two reactors (60, 70) capable of operating in an adsorption mode and a desorption mode and two liquid atomization units (62, 72) respectively in fluid communication with the reactors (60, 70). The liquid atomization units (62, 72) being capable of atomizing liquid to form adsorbate vapor or to condense desorbed vapor. In operation, the reactor in the adsorption mode adsorbs the adsorbate vapor and the reactor in the desorption mode produces desorbed vapor that is condensed by the atomised liquid.

  • Publication number: 20120006049
    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.
