Pls. Answer thank you! An air-conditioning system is used to maintain a house at 65°F when the temperature outside is 85°F. The house is gaining heat through the walls and windows at a rate of 1250 Btu/min, and the heat generation rate within the house from people, lights, and appliances amounts to 350 Btu/min. Determine the minimum power input required for this air-conditioning system
3.) When a gas surrounded by air is compressed or expands adiabatically, its temperature rises or decreased even though there is no heat input or dissipated to the gas. Where does the energy come from to raise or lower the temperature? 4.) Why must a room air conditioner be placed in a window rather than just set on the floor and plugged in? Why can a refrigerator be set on the floor and plugged in?

Hello Sir,Good Morning.I have a question in my homework related thermodynamics lesson. The following below is my question. Please advice. Thank you. Regards,Irfan An air conditioning system is used to keep the house at 65°F when the outside temperature is 85°F. The house gets heat through the walls and windows at a rate of 810 Btu/min, and the rate of heat generation inside the house from occupants, lights, and equipment is 120 Btu/min. Determine the minimum power input required for this air conditioning system.
During an average year of operation, the heat pump described in Part (a) above provides 15kW of heat to the house while using a total of 4.29kW of electricity. Using this information, calculate the Coefficient of Performance of the heat pump? A deep retrofit is beihg carried out on a domestic dwelling house to achieve an “A" Building Energ Rating. As part of this retrofit, an air-source heat pump is being installed. Using a detailed diagram describe the operation of an air source heat pump, showing the various components, identifying the working fluid, and how the heat is transferred.
13 .Mexico's metro requires the implementation of an air conditioning system for each of its cars. On the hottest days the air inside the car can reach 45°C. A temperature of 25°C is expected to be achieved to keep passengers satisfied. A car measures 17 m x 2.5 x 2. In order to make the decision on the air conditioning system to install, the engineering director has asked to calculate: A. Amount of energy to be removed from the car when the air is at 45°C and the car is empty. B. Amount of energy to withdraw when the car is full (approx. 130 people with a volume of 0.06 m3/person). Each person releases 30 kJ while in the car. C. Power of a system that removes the estimated energy A and B in less than 1 minute.
