Spring: Evap. Cooling

When it comes to keeping your home comfortable during our warm summer months here in the valley you have some choices to make. Around here, swamp evaporative coolers are pretty popular. We have a dry climate (usually) and we can capitalize on that with evaporation to cool our homes.  Evap. coolers use water and air to cool your home. The process of air flowing over the water causes evaporation, during that process heat is removed from the air, resulting in fresh cooled out-side air.

Different coolers offer different cooling abilities and it is important that you have the correct cooler for your home. The cooling capacity has to do with the size of the cooler, the size of the motor, size and number of duct runs, size of your home and the type of media used for evaporation. Some coolers offer aspen pads, while others  use a cardboard composite, like this:

Maintenance is a must, coolers must be started in the early summer and winterized to prevent damage before the first freeze. Most coolers require draining and disconnect from a water source when you shut it down, and many people opt to place a cover over the unit for the winter. Placing a cover over the unit helps keep the dust out while also helping to keep heat in your home in the winter.

While the unit is in operation windows must be opened to allow proper air flow. Evap. coolers do not (generally) have a return air duct like A/C, so when blowing air into your home it needs some place to go. Other options, such as Up-Ducts can be installed in your home so windows do not need to be open. For the freshest and coolest air, the air in you home must be circulated in 3 minutes or less, otherwise a humid “muggy” feeling can occur.

Yes, these evap. coolers do put humidity into your home, and many people enjoy this during our hot dry summer. In late July and August some humidity does come into our area, at this time the cooler will not work quite as well, but rest assured, it is still doing what it can to cool your home.
