![]() The process involves changing it from a liquid state to a gaseous state. When hot air flows over the coils, the coils absorb the heat. The process also acts as a dehumidifier, drying the inside air.Īn air conditioner contains evaporator coils fill with refrigerant. They are thermostat controlled and unlike swamp coolers, they can significantly lower room temperatures. The major components are a condenser, compressor, expansion valve and evaporater. In places where triple digit heat is the norm, refrigerated air is a better choice.Īir conditioners are a more complex system than swamp coolers. If it’s 110 degrees outside, you need to lower the temperature inside by more than a few degrees. Evaporative coolers are limited in that they can only lower the temperature a few degrees below the ambient temperature of the room. While places like Phoenix are very dry, the temperatures are consistently high. So one window must be kept open a few inches to keep the air flow continuous.Įvaporative coolers only work well in dry climates. Without proper ventilation, the air inside the home becomes overly humid. A steady supply of somewhere between 4 and 10 gallons of water is also required.Īir flow is crucial to an evaporative cooler. Only two components require electricity, the fan and the water pump. ![]() In an evaporative cooler, a fan blows water through absorption pads, effectively cooling the air by making it more humid.Įvaporative air coolers, often referred to as “swamp coolers”, are relatively simple in their construction. Hot air flows over water droplets, evaporating the moisture and reducing the temperature of the air. A real treat when you’ve been doing yard work in 110 degree heat.Īs a simple example, that’s evaporative cooling. The air that hit my face was deliciously cool. On hot breezy days I’d turn the hose on the juniper trees then stand in front of them. So you brave the heat, mow and pull weeds and prune your rose bushes, always with a garden hose close by to water plants and water yourself. The excuse “it’s too hot to do yard work” sounds good, but if you act on it there you won’t do any yard work from April to October. ![]() That said, there’s a difference between evaporative coolers and air conditioners. What’s the difference between a swamp cooler and an air conditioner?Īnswer: When we’re hot, we really don’t care how the air got cool. They had a swamp cooler in their adobe house. Question: I was visiting family in Las Cruces, New Mexico. ![]()
