Mini Split Heat Pump Sizing in Scranton – What Is an Air Well?

An air well provides a point for dew to condense, allowing for the collection of water. Variations on such equipment have been in use among various human cultures for thousands of years, particularly in arid regions where water supplies are limited. Using an air well permits people to harvest water from the air, in varying amounts, depending on humidity levels in the area. The technology can be used to supply safe drinking water and meet irrigation needs.

Several designs are in use, but the basic principle involves building a structure that can be cooled to a point lower than that of the surrounding area, which facilitates the formation of dew. Some air wells are passive, cooling without any need for energy use. They typically include a structure with a high surface area, which promotes heat loss. As air moves through the air well, condensation starts to form on the walls. Special materials can be used to trap the dew more effectively and funnel it to a collection area.

Other designs are active. In this type of air well, water or another coolant is circulated through the structure to bring the temperature down. This heat exchanger approach allows the structure to become much cooler, again promoting the formation of dew. 

An example can be seen with air conditioning systems, which can become accidental air wells if they are not designed and placed carefully. Droplets can start to collect on the equipment in high humidity because the air conditioner is so much cooler than the surrounding air.
