Wac (elec) The diagram depicts a portion of a DX air-conditioning system that provides cooling to one zone in a building. The outdoor unit provides heat-rejection and includes the compressor and the condenser fan. The indoor-fan moves air from the conditioned zone, across the cooling coil, and then back to the conditioned zone. The indoor-fan (with directly coupled motor) is located within the air-stream. Electric power consumption of the indoor fan motor is denoted Wm. The electrical power supply for...

Problem 3 A home in a Midwestern city is being heated with a heat pump in a winter day where the outside temperature is 5 C. Due to poor insulation, the home loses 800 KW of heat to the outside surroundings. An space heater inside the room generates 150 KW and another 120 KW of heat is generated by all the appliances and people in the room. The home is desired to be maintained at 25°C The heat pump consumes...

4. A new air-conditioner using R-410A is used in heat pump mode. The high pressure is 300 psia and the low pressure is 60 psia. It warms a house at 70 F driven by an electric power input of 2 Btu/s. The ambient is at 25 F. Assume the compressor is reversible and adiabatic, the stream leaving the condenser is saturated liquid, and stream leaving the evaporator is saturated vapor. Find...

A steam power plant operates with high pressure oft 4 MPa and hasleel receiving heat from a 700°C reservoir. The ambient air at 20°C provides cooling to maintain the water/vapor mixture in the condenser at 60°C. All components are ideal i.e., reversible) except the turbine which has an efficiency 92% of a reversible, isentropic process. Other than the irreversibility of the turbine, the power plant can be considered as a Rankine cycle. Determine the following quantities in the suggested...
