Seasonal solar system: AC-VG-25 vacuum solar collector

The solar collector is designed to heat large quantities of water during the spring-summer-autumn period.

The solar vacuum collector AC-VG-25 is designed for heating large quantities of water in the spring-summer-autumn period.

The collector is the central part of the solar water heating system. It is assembled from individual evacuated tubes, the necks of which are hermetically inserted into the manifold and the lower ends of which are secured to the collector frame. Using a selective coating on the evacuated tubes, solar energy is absorbed and converted into heat, heating the water in the tubes. The maximum heating temperature is 90°C. Because hot water is lighter than cold water, hot water naturally circulates to the top of the tube, while cold water circulates to the bottom. This circulation is based on the temperature difference. Cold water is forced into the manifold, which circulates downwards, thereby forcing heated water out of the tube and the other end of the manifold. The evacuated tube
