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.

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.

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.

Apparatus and method for control of solid desiccant dehumidifiers

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.

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.

System and method for improving the performance of desiccant dehumidification equipment for low-humidity applications

An active wheel desiccant dehumidifier is controlled for improved energy savings by modulating operation characteristics including process air flow, reactivation air flow, temperatures, and wheel rotation in response to changing conditions.
