Abstract:

A mathematical model for the direct evaporative cooling air conditioning is presented. Three dimensions solid evaporative cooling pad is regard as a big two dimensions plane. In order to avoid determining length and width of the plane, the set of partial differential equation is transformed to nondimensional form. Then directly calculate the product ( aaA) so as to avoid measuring aa and A. Finally, the set of partial differential equation can be solved.
