Swamp Coolers: How Do They Work?

Swamp cooling, evaporative, is a popular and affordable way to cool your house in the southwest. Swamp cooling works best when there is no humidity. Basic swamp cooling starts with a water pan. Water will naturally fill the pan as water evaporates. The water is pumped into a pan and then to a wet pad. It absorbs the water before it drains back into its pan. The wet plate filters the air drawn from the outside using a blower motor. Air is then pushed through a tube into the house. The wet pad cools the air and gives it humidity. Cooler air between supply and return will condition the whole home. The supply refers to the air coming out of the vents and registers of the house. The returns are an open window or door. The heat from the outside will be absorbed into the house by the air that circulates through it. The result is cooler and more manageable living conditions during hot, dry days.

How Does a Swamp Cooler Work?

Locate Your Swamp Cooler Control: This panel is identical to the controllers pictured below. There are several options. Also, it is important to know that there are manual and digital thermostat control systems.

Turn off The Fan and Turn on the Pump: If you have manual control, always turn on the pump for about five minutes to ensure the pad is adequately wet. Please turn on the fan and adjust it to low or high to circulate cool, fresh air throughout your house. You can set your digital thermostat to automatically allow the fan and pump to turn off.

Always Have A Window Open: to run your swamp cooler. Swamp coolers move cool air through your home’s air duct system. The hot air then gets pushed out of open windows. This is not refrigerated heating or air conditioning. You close your windows and doors when you turn on the air conditioner.

How to Make the Most of Your Swamp Cooler?

These tips are combined with a video showing you what you should do to ensure your swamp cooler is at its coolest. Contact a professional to evaluate your swamp cooler if you need something else.

Make Certain Your Pads Have Been Properly Dried: In case your swamp cooler stops cooling your home, first make sure that you check your pads for moisture. If your swamp cooler isn’t moist, it will blow hot outside air inside your home. Problems could arise if the pads aren’t getting wet. It could be an issue with your pump.

Do you have sufficient relief air? Ensure that there are enough windows open to vent the hot air. For cooler air to enter these rooms, be sure to open the windows in your hottest area of the house.

Buy A Digital Thermostat: A digital thermostat can be set to control the temperature of your swamp cooler.

Humidity: Your swamp cooler’s cooling efficiency depends on the outside humidity. Humidity levels that are too high will make it more difficult for your cooler to cool your home. The video below will explain how humidity levels affect efficiency temperatures.
