A refrigeration cycle operates at steady state between a how

A refrigeration cycle operates at steady state between a how reservoir at T_H of 300K and T_c of 270k. Determine the minimum theoretical power input in kWper kWof heat transfer from the cold reservoir. For reversible and irreversible power cycles, reversible and irreversible refrigeration cycles and reversible and irreversible heat pump cycles, all described below, show that. T_H > T_H for the power cycles.

Solution

>>Solution 5

As, for Minimum Theoretical Power Input, we will consider Reversed Carnot Cycle

So, COP = Q2/W = T2/(T1 - T2)

=> W/Q2 = (T1 - T2)/T2 = (300 - 270)/270 = 0.111

=> Required Power Input per kW of Heat transfer from Cold reservoir = 0.111 kW
