Atmospheric air at 32°C and 70% relative humidity passes through a cooling section in an air-conditioning duct where the air is cooled below its dew point and some of the water is removed. The air then passes over a heating section where heat is added until the final temperature is 22°C and the relative humidity is 45%. Assume the process occurs at constant pressure of 1 atm. Using the psychrometric chart, determine:
(a) The amount of water removed in the cooling section (kg of water/kg of dry air).
(b) The heat added in the heating section (kJ/kg dry air).
(c) Illustrate the processes on a psychrometric chart.

2. An air conditioning system is to take in air at latm 33C, 70% relative humidity and flow rate of 50m3/min and deliver it 23C and 60% relative humidity. The air first flows over the cooling coils, where it is cooled and dehumidified, and then over the resistance heating wires, where it is heated to the desired temperature. Assuming that the condensate is removed from the cooling section at 10C, determine: a) The temperature of the air before it enters...

Moist air at 24°C, 1 atm, and 35% relative humidity enters an evaporative cooling unit operating at steady state consisting of a heating section followed by a soaked pad evaporative cooler operating adiabatically. The air passing through the heating section is heated to 45°C. Next, the air passes through a soaked pad exiting with 50% relative humidity. Using data from the psychrometric chart, determine: (a) the humidity ratio of the entering moist air mixture, in kg(vapor) per kg(dry air). (b)...
