Swamp cooling, also called evaporative cooling, is a popular and inexpensive way to cool your home. The basic way a swamp cooler works is that it has a pan that holds water and automatically refills itself as water evaporates. The water is pumped from the pan to a pad, which soaks up the water and drains back into the pan. A blower motor pulls air from outside and sends it into the house through a duct, where a wet pad filters it. As the air passes through the wet pad, it gets cooler and more humid (this is where the evaporation happens). Between the supply and return, cooler air will be used to cool the whole house. The air coming out of the registers (vents) in the house is the supply, and an open window or door is the return.
How To Use A Swamp Cooler
- Find the swamp cooler’s control panel. The control panel for a swamp cooler looks like any of the panels shown below. There are also many different versions of these. Also, you should know that there are both manual and digital thermostat controllers.
- Turn on the pump. The first step is to turn on the pump to wet the pads before turning on the fan. If your pump has manual control, you should always turn it on for about 5 minutes to make sure the pads get enough water. Then you turn on the fan on high or low to start circulating cool air through your home. If you have a digital thermostat control, you can set a temperature threshold that will turn on the cooler and turn on the pump and fan automatically when your house reaches a certain temperature.
- Always open a window or two when your swamp cooler is running. As swamp coolers push cool air through the duct system in your home, the hot air is pushed out through open windows. This is the opposite of refrigerated air conditioning, in which you keep your windows and doors closed when the air conditioner is on.
How To Use Your Swamp Cooler Most Effectively
Here are some quick tips that show you what you can do to make sure your swamp cooler gives you the coolest temperatures. If you don’t feel comfortable doing any of these or getting on your roof, please call a professional to look at your swamp cooler.
• Make sure your pads are wet. If you feel like your swamp cooler isn’t cooling your home, the first thing to do is check to see if your pads are getting wet. If you don’t wet the pads, your swamp cooler will just blow hot air from outside into your home. If your pads don’t get wet, there may be a problem. There could be a problem with your pump or your water lines could be clogged.
• Do you have enough rescue air? – Check to see if you have enough windows open to get the hot air out of your home. Also, make sure to open windows in the hottest part of the house to bring cooler air into those rooms.
• Get a digital thermostat. With a digital thermostat, you can set a temperature for your swamp cooler to automatically turn on and off. This gives you better control over the temperature in your home.
• Humidity: The amount of humidity outside affects how well a swamp cooler cools. If humidity gets too high, your cooler will have a harder time bringing down the temperature inside your home.
