3.5 A heat pump is a closed system that operates steadily (or in cycles) while requiring the mechanical power input W, absorbing the heat transfer rate Qo from the ambient, and transferring heat at the rate QH to the inside of a house. In the steady state, the house temperature remains constant as the heating effect QH is balanced by the heat that leaks to the ambient through the house insulation. The heat pump operates irreversibly. Show that the power requirement of the heat pump is proportional to the rate of entropy generation in the entire region where the temperature is higher than the ambient temperature To. Which features and components are responsible for this entropy generation rate?

A refrigerator is operating at a steady state with COP 4.5 and power input 0.8kW. If energy is rejected from the refrigerator to the surroundings at 20 degrees Celsius due to heat transfer from metal coils, the rate of energy rejection is computed as ____kW and the lowest theoretical temp inside the refrigerator is ____ degrees Celsius
Two reversible cycles are in series, each process doing the same net work, Wcycle. The first cycle receives energy QH by heat transfer from a hot reservoir at 1000°R and energy Q is reinjected by heat transfer to a reservoir at an intermediate temperature, T. The second cycle receives energy Q by heat transfer from the reservoir at temperature T and reinjects the QC energy by heat transfer to the reservoir at a temperature of 400°R. All energy transferred is positive in the direction of the arrow. Determine: a) the intermediate temperature T, in °R, and the thermal efficiency for each of the two cycles; b) the thermal efficiency of a simple reversible cycle operating between the hot and cold reservoirs at 1000°R and 400°C, respectively. Then determine the net work done by the simple cycle, expressed in terms of the net work done by each of the two cycles, Wcycle.

3) When a person enters his house, which is completely closed in summer, he sees that the temperature is 34°C. After turning on the air conditioner, the temperature of the house becomes 22 °C within 15 minutes. Since the efficiency coefficient of the air conditioning system is 3.2, a) the electrical power drawn by the system, b) heat dissipated to the environment, and c) Assuming that it works 8 hours a day and the electricity price is 0.6 TL per kWh, find its cost for 4 months. Assume that the entire mass inside the house is equivalent to 1000 kg of air. For air, take Cv = 0.73 kJ/kgK, Cp= 1.0051 kJ/kgK.
