Question 1 - Section A: (i) Air can be heated either by using an electrical heating coil or by injecting hot steam. Using sketches of the psychrometric chart, compare the above two methods of heating the air. (ii) Briefly describe two practical ways to implement evaporative (adiabatic) cooling in an air- conditioning system. (Naming the methods without describing will not be sufficient). (iii) Briefly discuss two methods you can use to eliminate or minimise harmful pathogens in the conditioned air that you supply into a large building.

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.
