Do those mister's really work? I remember liking what I saw from the promo's but there seemed to be a lot of people claiming snake-oil.

- mchannon 9y agoI've never owned one, but the physics are pretty straightforward. The greater concern is longevity. I seem to recall a refrigerated air unit will use about 15% of its energy to cool its hot side and about 85% to pump the heat from cold side to hot side. So even if this eliminates that entire 15%, you're still going to be putting a lot of juice into that heat pump.
- brudgers 9y agoEvaporative cooling is more useful in dry arid climates. If you live in Pheonix, AZ, you may get by with nothing but a swamp cooler [1]. If you live in Phenix City, AL, you'll just get mold because the relative humidity is high. So if spraying water on your coils will cool them, then a swamp cooler may be a better option. At large scale, evaporative cooling works even in humid climates but by large scale I mean upwards of 20 tons [2] square feet plus a place to put industrial level noise.

It equates to upwards of 12,000 square feet of conditioned space.
