| Abstract: | This paper presents a simple
and efficient methodology to design a household desert cooler, predict
performance of
evaporative medium and
determine pad thickness and height for achieving maximum cooling. Inputs for
formulation include inlet
air DBT and humidity ratio,
air velocity, water temperature and flow rate, and geometrical properties of
evaporative medium. A
test rig was designed and
fabricated to collect experimental data. Predictions of air condition at cooler
outlet for given input
conditions agree
satisfactorily for air exit temperature (+15%) and humidity ratio (+10%).
Results are useful for size selection of
medium geometry required for an evaporative cooler design. |
