In extremely arid climates swamp coolers are great. Add a twinge of humidity and they’re useless. Swamp coolers, or evaporative air cooler, operate by injecting moisture into the atmosphere, and that moisture absorbs a large amount of heat as it evaporates. If the temperature is 90 degrees and the relative humidity is 25 percent or less, a swamp cooler provides cost effective cooling. If the humidity is 40 percent, the effect is negligible. Think of being outdoors in the heat and spraying water onto your exposed arm, chest and face. In arid climates, that mist will evaporate almost immediately, cooling those surfaces. In a humid environment, the atmosphere is already saturated, so there’s little, if any, evaporative/cooling benefit. You just have a sweaty and wet arm, chest and face. Swamp coolers were the norm in Albuquerque 40 years ago. The climate has changed, the humidity has risen, and people renting or selling houses feature retrofits to refrigerated cooling as a major selling point. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.
