Design and Fabrication of 360◦ Cooler cum Heater

Abstract

The evaporative cooling and forced convection heater is one of the earliest methods employed by men for conditioning their houses. Only in recent years, it has been put on sound footing thermodynamically. Evaporative cooling is a process of adiabatic saturation of air when a spray of water is made to 360 degree evaporative cooling pads without transfer of heat from or to the surroundings. Simple 360 degree evaporative cooling is achieved by direct contact of water particles & a moving air stream. If the water is circulated without a source of heat & cooling, dry air will become more humid & will drop in temperature. Simple 360° cooling is achieved by direct contact of water particles & a moving air stream. If the water is circulated without a source of heat & cooling, dry air will become more humid & will drop in temperature. In a complete contact process, the air would become saturated at WBT of the entering air.
