AB  - Evaporative cooling, used in many industrial and residential applications, is a complex coupled heat and mass transfer process where fluid cooling occurs due to water vaporization and the conversion of sensible to latent heat. In this paper, the development, testing, and implementation of a small, highly visual, Low-Cost Desktop Learning Module (LCDLM) for demonstration of evaporative cooling phenomena in the undergraduate classroom will be presented. The newly developed cross-flow direct evaporative cooler module is constructed from inexpensive expanded aluminum packing media, an off-the-shelf, battery-powered computer fan, a simple water distribution system with a battery-powered pump, and clear acrylic housing. The LCDLM is operated in a non-steady-state recycle mode where a small volume of water is circulated and, depending on the water temperature, either heats or cools incoming air. Preliminary data for simple experiments that can be repeated in the classroom are presented showing the effect of varying the initial water temperature, water flow rate, and air velocity on the cooling rate and temperature profiles in the module. These variables can be easily controlled in the classroom so that students can quickly observe their effect on the performance of the evaporative cooler. Finally, we outline worksheet and conceptual assessment questions to accompany classroom activities and present conceptual assessment results from a spring 2022 pilot classroom implementation of the evaporative cooler LCDLM in a Fluid Mechanics and Heat Transfer course. Significant student learning gains were observed after implementation, suggesting a positive influence of the LCDLM on understanding.
