6-103E An air-conditioning system is used to maintain a house at 70°F when the temperature outside is 100°F. The house is gaining heat through the walls and the windows at a rate of 800 Btu/min and the heat generation rate within the house from people, lights, and appliances amounts to 100 Btu/min. Determine the minimum power input required for this air-conditioning system.

Illustrate the contradiction between refrigeration cycles and the second law of thermodynamics while explaining how the efficiency of a refrigeration cycle could be higher than 100% and does not contradict with the Second Law of thermodynamics.
Rooms with floor areas of up to 15-m2 are cooled adequately by window air conditioners whose cooling capacity is 5000 Btu/h. Assuming the COP of the air conditioner to be 3.5, determine the rate of heat gain of the room, in Btu/h, when the air conditioner is running continuously to maintain a constant room temperature.

a student, observed that she can focus more in her lessons if the air conditioning unit in her spacious room is opened. She usually set the temperature to be maintained in her room at 10 C. The temperature outside of her room is 40 C. The refrigerant of her AC unit is HFC-134 a. What is the coefficient of performance of her AC unit if it is operating on a Vapor Compression refrigeration cycle? The compressor efficiency is 0.7.
A space to be air-conditioned has a sensible heat load of 34.9 hp and a latent heat load of 6.97 hp. The space is to maintained at 24°C DB and 17°C WB. Outside air is at 32°C DB and 24°C WB temperatures. With a re-heater to satisfy the space conditions, the conditioned air will enter the space at 18°C. If 40% of the supply air, is fresh air and the rest is re-circulated, find the specific humidity of outside air in kgv/kgda. The mass flow rate of supply air, ms is 312 kg/min. Take the mass flow rate of supply air, (ms = the sum of air mass flow rate to dissipate the sensible heat, msh, and the air mass flow rate to dissipate the latent heat, mlh). Take cp of dry air = unity. A) 0.0155 B) 0.0070 C) 0.0130 D) 0.0092
Refrigerant vapor rejects 70 kW of heat as it passes through an air-cooled condenser. The condenser has an air-side area of 210 m2 and, based on this area, has an overall heat transfer coefficient of 0.037 kW/m2∙°C. Cooling air flows at a rate of 7.59 kg/s. If condensation of the refrigerant occurs at 55°C, what is the inlet temperature (in °C) of the air? Take the specific heat of air to be 1.02 kJ/kg∙°C.
