Evaporative Cooling v’s Air Conditioning in the UK
Evaporative Cooling
• As outside temperature increases, evaporative cooling increases in capacity / effectiveness / performance
• At temperatures well above design parameters, evaporative cooling keeps working
• As doors are opened and/or left open, evaporative cooling maintains control and keeps working
• Evaporative coolers have only a few moving parts, all of which can be replaced easily in minutes if they fail
• Evaporative cooling systems use fresh air to deliver free cooling when it’s cooler outside, saving energy, wear on components and money
• Evaporative cooling can be used to cool just small parts of a large open building (Spot cooling)
• Properly designed evaporative cooling systems maintain a natural moisture level without excessive humidity
Air Conditioning
• As outside temperature increases, air conditioning decreases in capacity / effectiveness / performance
• At temperatures well above design parameters, air conditioning fails completely
• As doors are opened and/or left open, air conditioning loses control and possibly fails completely
• Air conditioners have many moving parts, most of which take hours to replace and need specialist equipment and labour
• Air conditioning re-circulates internal air, and may need to run even when it’s cooler outside
• Air conditioning does not work well in parts of a large space, unless physical partitions are installed
• Air conditioning dries the air, increasing static build up and decreasing comfort levels
