Evaporative cooling is a technique that utilizes water evaporation for endothermic refrigeration. In the absence of other heat conditions, water and unsaturated air between the heat and moisture exchange process is the water from air to absorb sensible heat and vaporize and evaporate into the air, the air due to moisture absorption and moisture content increases, the air lost the sensible heat and the temperature drops, but the total heat of the air remains the same Theoretically, both the water temperature and the air temperature will reached the wet bulb temperature of the air. According to this principle and the development of equipment known as evaporative cooling equipment.
What are the advantage of evaporative cooling ?
The efficient of evaporative cooling for this technology in compelling. Compared to the energy shortage in the mechanical refrigeration system, the evaporative cooling system requires only a simple fan transfer air and basic pump for keeping the unit wet. From the point of view of the size of equipment and the complexity of overall system. Evaporating cooling system are also easy to maintain compared to conventional computer room air conditioning. Evaporative cooling in environmentally friendly because the refrigerant is not like chlorofluocarbons or toxic chemical, but is a common daily water.
Evaporative cooling system is the biggest disadvantage of humidity, steam for such a climate as the desert is very useful, but only rely on these humidity is not enough. At the same time, evaporative cooling requires frequent supply of watering dry and dry areas can not work effectively.
Including the emergence of algae and the smell of its production, such as the breeding of flies in the water and other pests, while working with mold caused by mold problems cause by the workers healthy potential concern.
If you are using an evaporative cooling system, you only need to place the evaporative cooling system on a small number of servers, operate at high temperature, and improve data center efficiency.
