Carousel heat exchanger for sorption cooling process
First Claim
1. A carousel heat exchanger comprising:
- a) plurality of heater tubes disposed radially about a rotational axis, each of said heater tubes being sealed and having a hollow bore, said hollow bore being uniformly lined with a solid sorbent and containing a refrigerant;
b) a baffle disposed about said rotational axis, defining an outer zone and an inner zone having said heater tubes passing transversely therethrough, said baffle defining a first internal zone of said heater tubes in said outer zone and a second internal zone of said heater tubes in said inner zone;
c) a plurality of vanes disposed radially along said rotational axis, and extending transversely through said baffle, said vanes defining a plurality of axial flow segments, that subdivide said inner and said outer zone; and
,d) a manifold for moving a flow of a heat carrier into a portion of said axial flow segments in said outer and inner zones.

Abstract
A carousel heat exchanger is provided for air conditioning or waste heat recovery applications. The carousel heat exchanger includes a plurality of heater tubes disposed radially about a rotational axis. Each of the heater tubes is sealed and has a hollow bore which is uniformly lined with a solid adsorbent and contains a refrigerant. A baffle is disposed about the rotational axis such that to the heater tubes extend transversely therethrough. The baffle defines an outer zone to the outside of the baffle and an inner zone to the inside of the baffle and divides the heater tubes into a first internal zone of the heater tubes located in the outer zone and a second internal zone of the heater tubes located in the inner zone. A plurality of vanes is disposed radially along the rotational axis. The vanes extend transversely from both sides of the baffle, defining a plurality of axial flow segments that subdivide the inner and outer zones. A manifold moving a flow of a heat carrier into a portion of the axial flow segments in the outer and the inner zones is provided. Using the carousel heat exchanger of the present invention, particularly with an adsorbent selected from the group consisting of zeolite Y-54, zeolite Y-85, calcined low cerium rare earth exchanged zeolite Y-84 and calcined rare earth exchanged LZ-210, can result in significant improvements in cooling and waste heat recovery system power per unit-mass of sorbent, and can simplify the manufacture of sorption cooling systems.
