Question: An ideal vapor-compression refrigeration system operates at steady state with Refrigerant R-12 as the working fluid. Superheated vapor enters the compressor at 25 lbf/in2, 10oF
An ideal vapor-compression refrigeration system operates at steady state with Refrigerant R-12 as the working fluid. Superheated vapor enters the compressor at 25 lbf/in2, 10oF and saturated liquid leaves the condenser at 200 lbf/in2. The refrigeration capacity is 5 tons. Determine
(a) The compressor power in horsepower,
(b) The rate of heat transfer from the working fluid passing through the condenser, in Btu/min, and
(c) The coefficient of performance (COPR).
