Question
A 50-ton vapor compression refrigeration system is to evaporate R-12 at -20°C and to
condense it at 40°C. The vertical compressor is to run at 10000 rpm; it is double acting, has the bore equal
to the stroke, and has 10% clearance. Vapor enters the compressor at -10°C and liquid enters the expansion
valve at 30°C.
