What is evaporative cooling and how does it work?
Evaporative cooling is the conversion of liquid water into vapor using the thermal energy in the air, resulting in a lower air temperature. Evaporative cooling therefore causes a drop in the temperature of air proportional to the sensible heat drop and an increase in humidity proportional to the latent heat gain.
Is evaporative cooling any good?
One of the main advantages of an evaporative cooling system is that it provides fresh, clean air. An evaporative unit circulates outside air and filters out all harmful dust particles and allergens. With an evap cooler your home becomes hygienic and a safe environment for those who suffer from airborne allergies.
How does evaporative cooling work?
An evaporative cooler, sometimes referred to as a swamp cooler, utilizes water-soaked pads to cool the air. This process works because a fan pulls hot air into the unit, sending it through a series of pads that helps evaporate the liquid into a gas which then blows out cooler than it was when it entered the unit.
What is the difference between evaporative cooling and air conditioning?
Differences Between an Evaporative Cooler and Air Conditioner. Generally, air conditioners use refrigerants to remove heat and moisture from inside a space. While evaporative coolers do use water to cool naturally, they do not produce any mist, fog or spray water.
Do you need to open windows for evaporative cooling?
For an evaporative air conditioner to work effectively, some windows or outside doors must be open, or some other form of ventilation provided. The best approach is to open the windows or outside doors that are the furthest away from the air conditioning vents or ducts.
How do I make my evaporative cooler colder?
10 Tips to Make Your Swamp Cooler Colder and More Efficient
- Use Your Swamp Cooler in a Dry Climate. The biggest mistake people make with their evaporative cooler is trying to use it on humid days.
- Use Your Swamp Cooler Seasonally.
- Open the Windows.
- Run a Dehumidifier.
- Cultivate a Green Thumb.
- Experiment With Positioning.
- Prime the Pads First.
- Use Cold Water.
Can you leave evaporative cooling on overnight?
Using Evaporative Air Conditioning in a Heatwave
This prevents excessive heat build-up. You can keep it running 24/7 until the hot spell ends. You can turn the aircon on to fan only over night if the night temperatures are in the mid 20s or keep it running over night if the temperature are close to 30 degrees.
At what humidity does evaporative cooling stop working?
Although evaporative coolers are energy-efficient and affordable cooling devices, they’re only suitable in certain environments, particularly in areas where temperatures rise above 80° F and humidity levels below 50%.
How much water does an evaporative cooler use per hour?
Evaporative coolers use both electricity and water. How much water is used depends on the humidity of the day and the fan speed that the unit is set to operate on. A portable unit might use up to 4 litres per hour while a central system could use as much as 25 litres per hour.
How many windows do you need to open with evaporative cooling?
This lets you use the evaporative cooler as a whole-house fan during mild weather. Control the cooler’s air movement through the house by adjusting window openings. Open the windows or vents on the leeward side of the house to provide 1 to 2 square feet of opening for each 1,000 cfm of cooling capacity.
How cool can an evaporative cooler get?
Portacool evaporative coolers CAN drop the air temperature up to 30°F when the air is very dry such as arid climates of the Southwest where relative humidity is typically 30% or less. That said, even in hot and humid areas such as Houston, you can still expect to achieve a 10°F-13°F drop in temperature.
Where is evaporative cooling the most effective?
Evaporative cooling is most effective in climates where average relative humidity is less than 30%. As humidity increases, and the cooling capability declines, the temperature difference between the outside and inside of the chamber decreases.
Which is better evaporative cooling or split system?
Evaporative cooling, as well as it may work in drier environments, does not tend to work as efficiently in environments of high humidity. On the other hand, split system AC will work just as well in humid climates as any other and is therefore a viable option no matter where homeowners live.
Which is better evaporative or refrigerated air conditioning?
Evaporative cooling is easily the cheaper option and can be up to 50 per cent cheaper to install and more than seven times cheaper to run. Refrigerated cooling gives a better result but will have higher running costs. Evaporative uses far less electricity, as the cooling process is more natural.
Is evaporative cooling cheaper than air conditioning?
EVAPORATIVE COOLING (otherwise known as swamp coolers)
Set up costs are slightly cheaper than the refrigerated air conditioning. Evaporative coolers use a lot of water and they will not work in humid climates so you might want to take that into consideration.
