The evaporative straw or pine filter is located in the tray, external air is pulled through the moistened straw causing evaporation over a large surface area resulting in the cooling of the passing air which is delivered to the internal vents. It also filters out dust, insects, and acts as a humidifier in very low […]
Evaporative Cooling: How much cooling can be expected?
You can get an idea of how much cooling can be expected in a particular environment by taking a look at the below graph which shows the temperature of the air blowing out of the Fresair unit versus the outside air temperature, in various relative humidities. Even in higher humidities a lot of comfort and […]
Evaporative Cooling: Cool Air Cycling
While dependent on the outside temperature, you should see 20°F-40°F reduction from the ambient temperature to the air emitting out of the vents. Fresair is not a traditional air conditioner, there are no coolants or compressors, which would kill the batteries. Fresair is a green product powered by a 12V power source, normally just the […]
