ABSTRACT:
A compressor-expander assembly for use in a refrigeration system which includes a housing defining compression and expansion chambers of generally cylindrical section arranged side by side. Compressor and expander rotors of cylindrical shape are journaled for rotation in the respective chambers. The rotor shaft is offset from the chamber axis so that the surface of each rotor extends closely adjacent to the wall of the chamber causing each chamber to have a convergent side and a divergent side. Equally spaced about the rotor periphery are a set of vanes having their outer edges extending into engagement with the walls of the respective chambers so as to define a series of compartments of changing volume. The compression chamber has an arcuate inlet port which extends over substantially the entire divergent side and a concentrated outlet port which is located near the end of the convergent side. The expansion chamber has a concentrated inlet port which is located near the beginning of the divergent side and an outlet port which extends over substantially the entire convergent side. A heat exchanger is connected between the compressor outlet port and the expander inlet port. In operation, ambient air drawn into the compressor inlet port is compressed in the convergent side accompanied by an increase in temperature, cooled by passage through the heat exchanger, introduced into the expansion chamber, and then expanded in the divergent side to ambient pressure accompanied by a sharp drop in temperature. The compressor outlet port and expander inlet port are relatively so positioned that a smaller volume of air is defined, at cut-off, between adjacent vanes at the expander inlet port than at the compressor outlet port, with the result that compressed air is conducted through the heat exchanger at substantially constant pressure.
