Solar collectors aim to convert solar radiation into thermal energy reducing heat losses. The vacuum tube solar collector consists of a set of cylindrical tubes. The tubes are made up of a selective absorber on a reflective seat and surrounded by a transparent glass cylinder.
Direct flow vacuum solar collectors have a central heat collector from the primary circuit in the upper part of the tube. Each tube is connected to this collector using an outward and a return circuit (sometimes they can reach 20 tubes).
As a result, solar water heating can be used to obtain domestic hot water (DHW) in order to supply heated water to heating systems, swimming pool heating, etc. In solar vacuum tube collectors, the insulating effect is achieved by a vacuum in a glass tube or the space of two concentric glass tubes.
