Expansion vessel sizing for solar collectors loop
The sizing has the following assumptions: Collector loop is closed and
when collectors are overheated the water/glycol mixture is vaporized
in the whole volume of collectors. No automatic air separator shoud be
instaled. Only security valve. Additionally the solar medium is
expanded by ten percent. No static pressure is assumed. I suggest
expansion vessel near collectors and security valve on top of the
collectors for manual discharge.
You should choose at least one liter bigger vessel than minimum!
