From the author: In the case of run-around loop systems there are different strategies for capacity control of the liquid flow to obtain optimal operation. Common alternatives are constant flow with variable temperature by means of a shunt group and variable flow by means of two-way valve. A more energy efficient way is direct flow control of a variable speed pump. In direct flow control a much smaller pump power is used compared to valve control. Shunt groups, in particular, result in pump power that is constant and unaffected by the real demand. Calculations based on measurements on a run-around loop system with direct flow control during three months show that the pump power after optimizing the flow can be reduced by 80 %.
