In the sweltering heat, keeping cool is of utmost importance. But choosing the best device to cool us off and keep us from getting too hot is not an easy task. Although both portable and evaporative air conditioners can be effective in cooling a living area, which one is best?
There are several key differences between swamp cooler vs evaporative cooler. These differences can help determine the best cooling device for you.
HVAC Units Use a Chemical Refrigerant for Cooling and Dehumidifying Indoor Air
Air conditioners cool homes with the cooling effect of adding cool air to replace hot air. An AC unit – whether it’s a central or portable unit or window Unit – consists of several coils or tubes that run from the inside to out. This loop contains a chemical refrigerant. The refrigerant is able to absorb heat from the house and then send it outside. As this happens, the AC unit releases cool dry air which lowers the temperature inside and reduces humidity.
An air conditioner can be described as a closed system. A home’s windows or doors should be closed in order for the unit can function effectively. To maintain a lower interior temperature, it is important to close any windows or doors that allow cool air to escape.
Evaporative Coolers Use Water to Humidify and Cool the Rooms
Evaporative coolers also cool down the air. They are less effective than air conditioners nonetheless. Also known as the swamp chiller an evaporative cooler uses water and fans to lower temperature. You can think about the way your body feels after you leave the shower. You feel cooler because the water on your skin evaporates. This is how a portable cooler that evaporates water works.
In an evaporative chiller, the pads are soaked in water. The fan pulls in warm air from the outdoors and places the damp evaporative cooler pad on top. The pads evaporate water, which lowers the temperature. The cool air is pushed out of the cooler by the fan.
Swamp coolers bring outside air into homes and improve indoor air quality. However, closed-system air conditioners are better for allergy sufferers.
Evaporative cooling systems are open systems. It means that some doors or windows must be at minimum partially open while they are being used to let warm air escape. Cooling the home while the windows and doors are open can increase the flow of fresh air and improve the air quality.
Although fresher, cooler air is sometimes viewed as a benefit to swamp coolers, it can also be harmful to allergy sufferers. People who are allergic to pollen or other indoor allergens will benefit more from portable air conditioners that operate with the windows open.
An air conditioner unit could be a better solution if you live near wildfire smoke or other air pollution. It is safer to keep doors and windows closed in such climates. Evaporative coolers can draw polluting substances like smoke into your residence.
Air Conditioners Can Be Used In All Climates
Evaporative coolers and portable air conditioners have important differences. Although an air conditioning unit works well in any climate, wet or humid, it is not the same for evaporative cooling units.
Evaporative coolants lower the temperature in space by passing warm, humid air over damp cooling plates. The indoor temperature will drop as the water evaporates. However, the indoor humidity will be increased because of the evaporating water. A higher humidity level can be beneficial in dry areas, like the Southwest.
