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.
Claims43
A device with a refrigeration or heat pump cycle comprising a combination of a mechanical vapour compression cycle and an adsorption cycle, the device further comprising:
- a first working fluid capable of being adsorbed and/or desorbed in an adsorption means;
- said adsorption means comprising two or more adsorption/desorption beds;
- said adsorption/desorption beds being connected to an evaporator means and to a condenser means through one or more dedicated direction altering means, and operable in an alternating manner
- a mechanical vapour compression unit to compress a second working fluid, the MVC refrigerant, and connected to the said two or more adsorption/desorption beds, which alternatively act as the condenser and evaporator of the mechanical vapour compression unit, the condenser providing the regeneration heat to the desorber bed of the adsorption section, and the evaporator providing the cooling to the adsorber bed of the adsorption section,
- wherein the heat pump cycle provides the useful heat for desorption and/or cooling for adsorption for the adsorption cycle.
A method for heat pump operation in a device with a refrigeration or heat pump cycle comprising a combination of a mechanical vapour compression cycle and an adsorption cycle, the device further comprising:
