ABSTRACT:
A regenerative sorption compressor assembly for use in a sorption compressor/refrigerator system. The regenerative sorption compressor assembly of the present invention comprises a series of sorption compressor elements connected to a flowing loop of heat transport fluid. The compressor elements are heated and cooled by the heat transport fluid. At some point in the loop the fluid path is broken and the fluid is diverted to a heat source. At another point in the loop the fluid path is broken and the fluid is diverted to a heat sink. The points at which the heating and cooling flows are diverted are switched from compressor element to element in the direction of fluid flow at such a rate that the thermal capacity rate of the fluid in the heat transport loop relative to the moving switch point is equal and opposite to the thermal capacity rate of the compressor assembly relative to the switch point. The unique thermal recovery concept of the present invention provides a significant improvement in operating efficiency for a cryogenic refrigerator.
