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...

3. The outdoor air enters an AC system at 10°C and 75% relative humidity at a steady rate of 26 m3/ min, and it leaves at 25°C and 45% relative humidity. The outdoor air is first heated to 21°C in the heating section and then humidified by injection of hot steam in the humidifying section. Assuming the entire process takes place at 1 atm, determine (a) the rate of heat supply in the heating section, and (b) the mass flow...

An air conditioning system operates at a total pressure of 95 kPa and consists of a heating section and a humidifier that supplies wet steam (saturated water vapor) at 100°C. Air enters the heating section at 10°C and 70 percent relative humidity at a rate of 35 m/min, and it leaves the humidifying section at 20°C and 60 percent relative humidity. Determine (a) the temperature and relative humidity of air when it leaves the heating section, (b) the rate of...

Air enters a heating and humidification system at 5◦C, 50% relative humidity. The air first passes over a heater, and is then humidified with steam. The steam is supplied at 200 kPa pressure and 300◦C. The air leaves the system at 30◦C, 60% relative humidity. (a) Determine the heat transfer to the air, per unit mass dry air. (b) Determine the temperature and relative humidity of the air leaving the heating section (i.e., prior to the humidification section). (c) Determine...

Moist air enters a duct at 10 °C, 80% relative humidity, and a volumetric flow rate of 150 m3/min. The mixture is heated as it flows through the duct and exits at 30 °C. No moisture is added or removed and the mixture stays at 1 atm. Determine the rate of heat transfer and the relative humidity at the exit.

Moist air at 20°C, 1 atm, and 43% relative humidity and a volumetric flow rate of 900 m/hrs. enters a control volume at steady state and flow along a surface maintained at 65° C, through which heat transfer occurs. Liquid water at 20° C is injected at a rate of 5 kg/hr and evaporates into flowing stream. For the control volume, Wev =0, and kinetic and potential energy effects are negligible. Moist air exits at 32°C, 1 atm. (a) draw...
