An ordinary vapor compression refrigeration cycle using R134a is to operate with a condenser at 45 C and an evaporator at -10 C. The compressor is 80% efficient.
(a) Determine the amount of cooling per kg of R134a circulated
(b) determine the amount of heat rejected per kg of R134a circualted.
(c) Determine the work required per kg of R134a circulated, and the COP.
