This block computes the load on a system based on the return temperature, active supply temperature setpoint and measured flow through the associated circuit flow meter, using the following equation.
Q_flow = V_flow * rho_default *
cp_default * (TSupSet - TRet)Q_flow = V_flow * rho_default *
cp_default * (TRet - TSupSet)Q_flow less than or equal to
zero means that there is no actual load on the system.The output load QReq_flow is the rolling average of
Q_flow over a period of dtMea.
