Heat transfer on A/C humidifier operating by solar energy

A solar humidifier unit used for humidification of an air conditioning syst em is presented. A Runge-Kutta procedure of fifth order has been used to so lve the governing equations. Solar energy data as well as ambient temperatu re data for one hot summer day were used in calculation the inside temperat ure of the humidifier as well as other parameters to determine the effectiv e use of the solar humidifier. The results obtained are promising to corpor ate it with an A/C system. The amount of vapor produced reaches a maximum v alue at the time when the ambient temperature reaches also a maximum value and the relative humidity reaches a minimum values.
