  • Publication number: 20240019135
    Abstract: Described herein is an apparatus and method for removing moisture and/or sorbates from airstream and/or other fluid. The system comprises a preconditioning desiccant wheel and a main desiccant wheel. The preconditioning desiccant wheel comprises of at least two first sectors for allowing air to pass therethrough, including a first process sector and a first reactivation sector. The main desiccant wheel comprises of at least three second sectors for allowing air to pass therethrough, sequentially including a second outside air sector, a second process sector, and a second reactivation sector. The ambient airstream is sequentially dehumidified in one of the at least two sectors of the preconditioning desiccant wheel and the outside air sector of the main desiccant wheel, before being at least partially supplied for reactivation to the reactivation sector of the main desiccant wheel.

  • Patent number: 10837682
    Abstract: The present invention provides a device with a combined hybrid mechanical vapour compression-adsorption cycle, particularly to devices used in moisture or temperature control applications which incorporate or embody refrigeration or heat pump cycles, such as for example HVAC applications. In this invention, heat from the adsorption process and/or condensation process of the adsorption cycle is pumped to the desorption process. Thus, this new hybrid combined cycle becomes a partially or fully electricity driven heat pump cycle.

  • Publication number: 20180283744
    Abstract: The present invention relates to a novel split level sorption refrigeration system. In particular, the present invention provides a split level sorption based unit as a novel method of using the traditional sorption based refrigeration unit. The present invention offers orientation free configuration with efficient cooling power delivery to the various cooling load locations which is achieved by splitting the evaporator of the sorption chiller from the sorption beds and the condenser.

  • Patent number: 9777933
    Abstract: The present invention generally discloses desiccant dehumidifiers control systems. In particular, the present invention relates to solid desiccant dehumidifiers which use a rotor (commonly called a wheel) to dehumidify a process airstream. The invention provides a novel apparatus for control of desiccant dehumidifiers and to an improved method of control of such dehumidifiers, and also to dehumidifiers provided with such control systems.

  • Patent number: 9534840
    Abstract: The present invention relates to a method for moisture determination and control using real time measurement of the moisture content of the material being processed. The present invention also provides a device that is used for moisture determination and control based on real time measurement of moisture content of a material being processed. The present invention is particularly suitable for controlling the moisture content of a material in a drying process, such as in a drying hopper, where the material moisture content is measured at an inlet and an outlet of the drying process. The drying process is further controlled by anticipating the drying load by measuring the moisture content of the incoming material to be dried.

  • Patent number: 9303884
    Abstract: A method and apparatus for energy-efficient desiccant dehumidification of air or other gases to low humidity levels is disclosed. The method and apparatus includes a desiccant rotor (wheel) having more than one dehumidification zone or sector. Separate dehumidification sectors may be used to dehumidify separate air or gas streams, or they may be used to dehumidify a single air or gas stream by passing it through more than one sector. All or a portion of the discharge air or gas from a dehumidification sector is used for all or a portion of reactivation inlet air or gas prior to heating. The desiccant wheel may include more than one reactivation sector, with separate air or gas sources for each sector. The desiccant wheel may include a purge sector between the reactivation and dehumidification sectors to improve the thermal efficiency of the dehumidification process.
