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.
