Reverse Circulation In Thermosiphon Systems
Installing check valves on the solar heat tubes can prevent reverse flow. Place the check valves in-line with the flow direction, ensuring the valves are oriented correctly. Use gravity loops or thermosiphon breaks: By installing gravity loops or thermosiphon breaks in the solar heat tube system, you can create barriers to reverse flow.
