Abstract
Energy and mass are transferred in a system utilizing a gaseous refrigerant which is mixed and sorbed (absorbed/adsorbed) with a liquid carrier selected from the group consisting of long chain alcohols, ethers, glycols, glycol ethers, sebecates, phthalates, aldehydes and ketones, and sorbate/liquid mixture then combined with a particulate solid capable of forming a solid/gas compound with the gaseous refrigerant. The process is carried out in a mass and heat exchange apparatus capable of collecting and transferring the energy created by the formation or dissociation of the solid/gas compound.
Claims14
Apparatus in which mass and heat are transferred between a mixture of a liquid and particulate solid comprising
- a container having a cavity for receiving said mixture,
- a plurality of heat exchange surfaces in said cavity having means for transferring heat therefrom to and from said liquid and particulate solid in contact therewith, each said surface disposed at a different elevation from the other of said surfaces and tilted with respect to horizontal for gravitationally feeding said mixture successively along said surfaces from the uppermost surface, and
- first pump and conduit means for pumping said mixture from the bottom of said cavity to the uppermost of said heat exchange surfaces.
Apparatus in which heat and mass are transferred between a liquid and a particulate solid comprising
- a container having a cavity for receiving said liquid and said particulate solid and a refrigerant gas,
- an upper and a lower porous wall impervious to said particulate solid in said cavity and defininng a chamber therebetween for holding said particulate solid, and having an upper cavity portion above said upper wall and a sump cavity portion below said lower wall,
- first pump and conduit means for pumping said liquid between said sump cavity portion and said upper cavity portion, and
- a first heat exchanger in heat exchange communication with said first conduit means.
Apparatus in which mass and heat are transferred between a liquid and a particulate solid comprising
- a container having a cavity containing a layer of a mixture of said liquid and said particulate solid on the bottom thereof, a layer of said liquid lying on top of said layer of said mixture, and a space above said layer of said liquid,
- a plurality of heat exchange surfaces in said cavity having means for transferring heat therefrom to and from said liquid and particulate solid in contact therewith, at least two of said heat exchange surfaces being disposed in said space at different elevations from each other and tilted with respect to horizontal for gravitationally feeding said mixture successively along said surfaces from the uppermost surface,
- first pump and conduit means for pumping said mixture from the bottom of said cavity to the uppermost of said heat exchange surfaces, and
- second pump and conduit means for pumping said liquid from said layer of said liquid to said first conduit means,
- whereby said liquid from said liquid layer is mixed with said mixture in said second conduit means prior to being deposited on said uppermost of said heat exchange surfaces.
Apparatus in which heat and mass are transferred between a liquid and a particulate solid comprising
- a container having a cavity containing a first layer of a mixture of said liquid and said particulate solid and a second layer of said liquid contiguous with said first layer, said cavity including a space above said first and second layers,
- first distribution means for directing said liquid into said space,
- first pump and conduit means for directing said liquid from said layer thereof to said first distribution means, and
- a first heat exchnager in heat exchange communication with said first layer of said mixture in said cavity for directing heat to or from said mixture, and a second heat exchanger in heat exchange communication in said first conduit means for transferring heat to or from said liquid.
Apparatus in which heat and mass are transferred between a liquid and a particulate solid comprising
- a container having a cavity for receiving said liquid, said particulate solid and a refrigerant gas,
- an upper and a lower porous wall impervious to said particulate solid in said cavity and defining a chamber therebetween for holding said particulate solid, and having an upper cavity portion above said upper wall and a sump cavity portion below said lower wall,
- first pump and conduit means for pumping said liquid between said sump cavity portion and said upper cavity portion, and
- a heat exchanger in said chamber.
