Page 28: Function Of The Check Valves [Expert]
10 Function of the check valves [Expert] 10 Function of the check valves [Expert] Within their application range, the check valves of this station prevent unwanted gravity circulation. The functioning of the check valves depends on: the installation height • the temperature difference between the storage tank and the collector •... - Page 29 10 Function of the check valves [Expert] Do you wish to get further information? The density of the solar fluid decreases with rising temperature. In high installations with large temperature differences, the difference in density will cause gravity circulation. This circulation can lead to a cooling down of the storage tank.
