Summary

High performance air cycle refrigeration system has been developed and commercialized. Existing air cycle systems were unsatisfactory, because of the clogging problem caused by moisture and its lower efficiency than any system using HCFC or ammonia. By the examination of air cycle system, the authors determined the efficient range where the COP is almost equivalent to or higher than that of HCFC and ammonia system. The range is under -20°C of room temperature and under 35 kilowatts of cooling capacity. The application beyond the above range, usage of natural energy is suggested. Air cycle for train air conditioning is also introduced. The lower COP of air cycle in air conditioning range has been compensated for thanks to application in areas having a short hot season.
