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.
