This would effectively double the daily power usage of this system, requiring us to double up the 250Ah battery bank. The Viesa Holiday IIIs uses 0.5L – 1.5L per hour, which it takes from an integrated tank that must be topped up. The other consideration is that evaporative coolers use water when they are running. And if you take holidays to Mediterranean Europe, you’ll find your evaporative cooler even more effective there. Thus, an evaporative cooler is at its most effective during the hours when cooling is needed most. Humidity decreases as temperatures increase in the hottest part of the day. In that case, does the UK’s relatively damp island climate make evaporative cooling untenable? Well, many commercial buildings in the UK are turning to evaporative cooling for its low power requirements. Their main drawback is the fact that their efficacy decreases as outside humidity increases. The cooling effect is less profound, though some say that overall comfort is higher with an evaporative cooler due to their maintenance of a humidity level that’s optimal for human comfort. They have a more subtle effect, passing cool, fresh, humidity-controlled air into the room, as opposed to dry, thoroughly chilled air. This is in contrast to air con units, which have to work harder as it gets hotter outside.Įvaporative coolers won’t feel the same as air con units. Finally, the efficiency of an evaporative cooler actually increases as outside temperatures increase, as this promotes evaporation of water. Furthermore, evaporative coolers constantly pull fresh outside air inside, cooling it on the way, rather than recirculating stale air from inside the van. For example, the Viesa Holiday IIIs, a popular evaporative cooler for campervans, only uses 1.3A – 5.8A when running. The only powered components in an evaporative cooler are the fans and a small water pump, making them much less power intensive. This cool air is then blown into the indoor space. When hot outside air is passed through filters saturated with water, water evaporates into the air, cooling it down. Evaporative coolers are much simpler than air conditioning, with fewer moving parts.
