Problem 4- A HVAC system is operating in heating mode with a steam humidification system, as shown below. Air enters the system at 10°C and 70% relative humidity at a rate of 35m3/min. After heating and subsequent humidification by saturated water vapor at 100°C, the air leaves the system at 20°C and 60% relative humidity. Find (1) the temperature and relative humidity of the air when it leaves the heating section, (2) the heat transferred to the air in the...

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...
