A prototype design has been built to simulate natural draft wet cooling tower based on geometrical, dynamic and thermodynamic similarity. Experimental tests were done in summer (hot and dry) and at winter (cold and wet) weather according to Iraqi weather using (10) cm trickle fill. The mass flow rate of water has changed from (0.8 to 2.4) gpm, and cross wind fixed at zero (m/s). The obtained results clarify that tower range, cooling capacity, and air temperature change, are higher at winter than them at summer where relative humidity change, enthalpy change, and show higher values at summer than them at winter. It is found that water consumption in winter is more than it in summer in spite of the more humidity in outside weather at winter.
