The swamp coolers are a great way to cool and cheap cars in his shop in the summer.

A swamp cooler is essentially a large fan pads moistened with water in front of it. The fan draws hot air out through the pills and now blows the cooled air throughout the house. The pads can be made wood shavings – wood from poplar trees is a traditional choice – or other materials that absorb and hold moisture while resisting mildew. Pads Aspen wood, also called Excelsior, should be replaced every season or two, and generally cost $ 20 to $ 40 for a set.

Small lines distribution of water supply to the top of the pads. Water soaks the pads and, thanks to gravity, trickles through them to collect in a sump at the bottom of the refrigerator. A small water pump circulates the collected water back to the top of the pads. Then the process starts again.

Since water is continually lost through evaporation, a float valve – much like controlling the water in a toilet tank – adds water to the sump when the level is low. Under normal conditions, a swamp cooler can use between 3 to 15 gallons of water a day.

A wide range indicates air through the pads, where evaporation lowers the temperature of approximately 20 degrees. The fan blows the cooled air into the house. Small units can be installed in a window, blowing cooled air directly into a room. Larger units can blow air into one central location, or air can travel through ducts to individual rooms.

Normal air conditioning is a closed system, taking air from inside a house and recycling. For air conditioning to function properly, doors and windows should be closed. Swamp coolers, however, take the air outside the house. For a swamp cooler to work properly, the outside air cooling should be allowed to escape. By choosing which of your doors or windows left open house can help to direct the flow of cool air to areas where needed.
