This project is to design, construct and test a 25 ton air-cooled solar water chiller for multi-family and commercial applications. The design utilizes a dual loop Rankine power cycle driving a Rankine vapor compressor cycle. R-113, selected as optimum for this application, is common to both loops. The prime mover is a high speed turbo machine with gas bearings and a variable speed electric auxiliary energy source. During this period, the turbo machine was completed and successfully bench tested on an air loop to qualify the rotor dynamic design. The chiller, with turbo machine, was completed in a water cooled configuration to facilitate initial testing. The chiller was installed in a specially designed test loop with complete instrumentation and data acquisition equipment. A series of tests was initiated to qualify the turbo machine rotor dynamics and gas bearings in the R-113 working fluid under selected operating conditions. During these tests, a failure of the thrust bearing was experienced. A detailed analysis of this failure is presented in this report with recommendations for future work.
