Vacuum Tube Collector Solar
Vacuum tube collecor solar is one of the most popular water heating system for swimming pool. Vacuum tubes are made up of a double glass tube, between whose walls a very high vacuum is made (around 0.005 Pa) in order to minimize heat losses by conduction and convention. The glass surface of the inner tube usually has a selective sprayed metal-based coating to increase radiation absorption. In a vacuum collector, solar radiation passes through the outer glass tube, strikes the inner absorption tube, and is transformed into heat. The heat is transferred through its walls to the liquid that flows inside the inner tube. These vacuum tube collector solar allows water to be heated up to temperatures of 110 ºC, which makes it possible to use in water heating applications.
