Exploring Evaporative Cooling
Evaporation and condensation are integral processes of our lives. The very example of these processes resides in our body – perspiration. When the outer weather gets too hot, our body secretes water – sweat – to cool off the body. This sweat evaporates because of the hot weather, and this evaporation causes a cooling effect. The heat and the humidity in the atmosphere control how quickly you feel cooler; that’s why you feel hotter on a humid day than on a dry day. This is exactly the principle used in Evaporative Cooling within a datacenter. T he process of evaporative cooling has been used very commonly in homes for cooling during summers; the coolers are popularly known as swamp coolers. But it has recently entered the scene of datacenter cooling as an environment-friendly option, mainly because it doesn’t use a refrigerant for cooling. How does an evaporative cooler work? A datacenter consists of a lot of equipment which run continuously for a long time. That caus
