Using psychrometric chat to answer the questions below:
15 m3/min humid air is to be cooled using an air conditioning unit. The inlet air is at 35 °C and 60% relative humidity and should be cooled to 18 °C, at which point it will be saturated.
a) Below which temperature will condensation start occurring?
b) How much water will have condensed if cooled to 18 C (mw,out)?
c) Determine the heat removal, Qout, using the first law of thermodynamics.
