At steady-state, a reversible refrigeration cycle discharges energy at the rate H to a hot reservoir at temperature TH, while receiving energy at the rate C from a cold reservoir at temperature TC.
a. If TH = 13°C and TC = 2°C, determine the coefficient of performance.
b. If H = 10.5 kW, C = 8.75 kW, and TC = 0°C, determine TH in °C
c. If the coefficient of performance is 10 and TH = 27°C, determine TC in °C.
