1- An air conditioned space is maintained at DBT= 24 č and RH-50% .The out side condition is DBT=38 c with WBT= 27 c.The space has a sensible heat gain of 24 kW and latent heat gain of 6 kW. Use all out side air system and find :- a) the supply condition of the air if the relative humidity at the supply point is taken to be 90% . b) volume flow rate of supplied air. c) the total cooling load of the cooling coil. d) the chilled water volume flow rate if its temperature rise is 5.6c. ( answer : T, 12.2 c ,h, 32.6 kJ/kg .Qeoil =95.6 kW , 4.06e-3 m'/s) 2- The sensible heat gain of a given space is 50 kW and its latent load is 15 kW. The inside design condition is 26 c with 50% relative humidity. The space is air conditioned using all return air system Find by assuming 90% saturation for the supply air. a) the supply conditioned of the air b) volume flow rate of supplied air c) coling coil load
