Hi,

Sorry for the newbie questions here.

I'd like to design a system with a partially filled, atmospheric pressure tank, which is on the collector side and acts as the energy store and the drainback tank. I have found a template with a Chinese tank, which is partially filled with programmable controller, so it looks like what I want to do is possible in Polysun.

My questions are:
  • How do I add a vent to a tank to keep it at atmospheric pressure?
  • Am I missing some obvious drainback templates in Polysun?
  • How do I fit a pressure relief valve to a pressurised drainback system?

Many thanks in advance :)

Hi Lazster,

Thank you very much for your question.
Polysun focusses on the energy system design and to do so some system properties can be neglected. Therefore, Polysun does not include components such as pressure relief valves. Please feel free to contact us again when you need any help with the system design.
Kind regards,

Michael Hönes
