Air well (condenser)

An air well (or condenser) is a type of machine that helps to cool the air around us. It works by using a fan to take in hot air from the outside, then passing it over some special coils filled with cold water. The hot air from the outside is cooled by the cold water inside the coils and the cooled air is sent back out into the environment. This process helps to keep our homes and other places cool during the summer and helps to reduce the amount of energy we use to cool down the air around us.
