ABSTRACT:
A channel type diffuser is applied to a centrifugal compressor to obtain substantially complete expansion of the refrigerant downstream of the impeller wheel. The relatively large volume of expanded gases that results from such a diffusion process is accommodated by the use of a relatively large volume collecter with a uniform circumferential cross section. The result is higher efficiencies and a more stable operating range.
