Question: Problem 1. Design a vapor compression refrigeration unit using R290 as the refrigerant. The unit must be capable of pumping 1.5 refrigeration tons of heat

Problem 1.

Design a vapor compression refrigeration unit using R290 as the refrigerant. The unit must be capable of pumping 1.5 refrigeration tons of heat at 25C. The condenser will be operated using water at 25C. Determine the flow rate of the refrigerant and the coefficient of performance assuming the compressor to operate with 80% efficiency. Additional information: One standard refrigeration ton is 12,000 BTU/h (3,517 W).
