摘要

The performance study and complete design of a 25-ton multiple slide helical screw compressor for application in solar assisted heat pump systems have been carried out. The work entailed testing of a 100-ton 4-slide screw compressor that had been previously built, complete conceptual and detailed design of the 4-slide 25-ton compressor and an alternate 2-slide/fixed port configuration, thorough computer simulations of compressor performance, and design of a 25-ton test loop. Partial construction of the test loop and ordering of long-lead components for fabrication was also carried out. Testing of the 100-ton prototype was done to develop slide configuration and control technique, investigate oil system behavior, and obtained performance data at high and low speed. Results were input into the 25-ton compressor design. In the performance study, computer codes were developed to carry out the thermodynamic analysis of the vapor cycle using real vapor properties from standard refrigerant property tables. It is found that either the 4-slide or 2-slide compressor is technically attractive for solar assisted heat pump application and would be able to obtain high coefficient of performance and energy conservation, but little market is expected unless solar assisted heat pumps gain interest.
