Question

At steady state, a reversible heat pump cycle discharges energy at the rate Q˙H to a hot reservoir at temperature TH, while receiving energy at the rate Q˙C from a cold reservoir at temperature TC.


(a) If TH = 10°C and TC = 2°C, determine the coefficient of performance.

(b) If Q˙H= 15 kW, Q˙C= 8.75 kW, and TC = 0°C, determine TH, in °C.

(c) If the coefficient of performance is 5 and TH = 27°C, determine TC, in °C.

At steady state, a reversible heat pump cycle discharges energy at the rate Oy to a hot reservoir at temperature TH, while receiving energy at the rate Oc from a cold reservoir at temperature Tc. (a) If TH = 10°C and Tc = 2°C, determine the coefficient of performance. (b) If QH = 15 kW, c = 8.75 kW, and Tc=0°C, determine TH, in °C. (c) If the coefficient of performance is 5 and TH = 27°C, determine Tc, in °C.
