Mixing loops
Due to variations in use, flow temperature and heat
demand in different parts of the building, the heating
system should be divided into zones controlled by
independent mixing loops. Due to the flow variations, a
speed-controlled mixing-loop pump will have the
authority in the system. This will help obtain a better
hydraulic balance in the total system. Speed control of
the pump via selection of a control mode, depending
on system application, ensures maximum energy
saving. See section Selection of control mode, page
24.
Advantages of using mixing loops:
• Reduced excessive differential pressure in the
system and hereby reduced risk of overflow.
• Increased control ability as the loop is provided with
the exact flow and temperature demand.
