Using a evaporative cooling has long been the most energy efficient method of rejecting heat from air-conditioning. When used in conjunction with water cooled chillers it can offer a energy savings of over 20% alone. For every 1 K reduction in condensing temperature reduces the power consumption of a chiller by 3%. Since the wet bulbs use 6 to 12 K less than the dry-bulb temperature, energy savings of as much as 30% are possible. The new systems also leave a smaller footprint so take up less space to install leaving more room for other things. All this means is that using a evaporative cooling system could be the ultimate Green Machine.
