Re: [MBZ] Swamp cooler

Back in the fifties parents bought one of the first window units Sears sold. After it ran a while it was less humid in the living room, but it was vaguely uncomfortable. We checked and found that it had removed the humidity quite well but had not lowered the temperature. Sears replaced it with

Re: [MBZ] Swamp cooler

What we are talking about (and Curt mentioned it earlier) is the heat needed to convert the liquid water into gaseous water - the heat of evaporation, or latent heat. For water, it takes 2264.76 kJ/kg to evaporate the water. This heat is coming from the air. It will therefore drop the temperature

It's properly called "Evaporative Cooling" .. "swamp" doesn't correctly transmit the physics in play.. NM / AZ / NV .. "dry heat" areas "evaporate" moisture, Water droplets [moisture] in suspension in the air, absorb heat. Thus, in DC, with WET HEAT and very little evaporation, you "feel the

Re: [MBZ] Swamp cooler

Physics, Bunky, is the key to understanding life. The hot dry air evaporates water, which absorbs heat (the heat of vaporization) as it makes the transition from liquid to vapor, thus cooling the air from which that heat is extracted. You can get considerable temperature drop in the air, it

Re: [MBZ] Swamp cooler

Swamp coolers were the only cooling we had in the high desert of NM and CA, where I lived for 2 years and 5 years, respectively. They actually do a good job with low energy consumption providing (1) the ambient relative humidity is very low (like desert), (2) you start daily cooling long before

Re: [MBZ] Swamp cooler

A properly fitted evaporative cooler needs to be hooked to a water supply so it maintains a constant supply in the water pan.. otherwise, the water pump will run dry and burn up... so, different than the humidifier in that regard. Also.. the volume of water loss requires constant feed to the float
