Sizing expansion vessels
What is the rule of thumb for sizing an expansion vessel for a sealed
heating system? My application is not a domestic heating system but rather an unvented cooling system cooling a large industrial machine, but the principal is the same. The 'boiler' equates to the machine being cooled. the 'radiators' are a fan cooled bank of tubing and the water based coolant is circulated by a pump. Given the system volume = V and coefficient of expansion of water per degree is E and temperature rise is deltaT presumably : (V(orig) x E x deltaT) - V(orig) = the max increase in volume But what safety margins are applied in domestic heating systems? Do plumbers really calculate system volume ? AWEM |
