b
Size the solar expansion tank so as to ensure complete
absorption of the expansion of the fluid contained within
the system, with reference to the prevailing regulations on
the matter. In particular, consider fluid characteristics, con-
siderable fluctuation of service temperature and vapour
that might be generated during solar collector stagnation
stage. Proper size of expansion tank ensures setting off
of all volume changes of the heat transfer fluid, avoiding
excessive pressure increase. Limited pressure changes
avoid reaching safety valve opening pressure and the con-
sequent fluid drainage.
