- A room humidifier works as follows: a stream of air with 20% humidity and a dry bulb temperature equal to 20 °C is mixed with a stream of water also at 20 °C until saturation is reached. Then the saturated air stream passes through a heat exchanger where it is heated. Knowing that the flow rate of the air stream entering the humidifier is 100 m3/h and that the heat exchanger supplies 500 kcal/h to heat the saturated air stream, determinea) the minimum mass flow rate of the water stream to saturate the air stream.b) the temperature and humidity percentage of the air stream at the exit of the heat exchanger.

It is desired to reduce the temperature of the ambient air entering an air handling unit at a volumetric flow rate of 550 m3/min, at a temperature of 35°C and a relative humidity of 0.75 to 20°C and its relative humidity to 0.45. For this purpose, the air is first cooled to a temperature below the dew point by passing through a cooling coil, and after some moisture is taken by condensation, its temperature is increased to 20˚C by passing over a heating coil. In this way, the temperature of the ambient air at the outlet of the air handling unit is brought to 20˚C and its relative humidity to 0.45. It is assumed that the pressure remains constant at P=100 kPa. Relationships will be used in the calculations. a) Calculate the amount of moisture condensed per unit time.b) Find the amount of heat drawn from the air by the cooling coil.c) Calculate the amount of heat given to the air by the heating coil.d) Show the phase changes on the psychrometric diagram.
