ABSTRACT:
A thermal machine includes a horizontal rotatable shaft extending through a cylindrical housing which contains the at least high and low pressure stages. The shaft carries a pair of cylindrical drum heat transfer means within the housing to rotate with the shaft. All or part of both drums contain an intermediate pressure stage, with pool collection capability within the drums using annular rims to retain the absorbent solutions. The outer housing has means to permit collection of absorbent solutions in separate pools in contact with the respective outer sidewall surfaces of the drums. Such contact provides thermal coupling between stages. Additional sections of the drums may contain pools for external circulants, which drum sections also contact the pools in the outer housing. Sealing means permits rotation of the respective drum means but isolates the vapors within the drums from the pools within the outer housing and vapors from the outer housing pools from one another. Piping is provided for the flow of an absorbent solution among the vessels in different stages and conduits may permit vapor flow from one vessel to a second within a stage. In some applications, the drum may be corrugated and wiped for enhanced heat transfer.
