E1…E7
Energy types E1…E7 are described by application examples below.
Application no. 1
Closed thermal system with 1 flow meter
Heat energy: E1 = V1(T1-T2)k
T1:Inlet or T2:Outlet
Cooling energy: E3 = V1(T2-T1)k
T1:Inlet or T2:Outlet
Flow meter V1 is placed in inlet or outlet as selected
during PROG.
Mass: M1 = V1 (Kmass t1) or
Mass: M1 = V1 (Kmass t2) depending on Inlet/Outlet
programming.
Application no. 2
Closed thermal system with 2 identical flow meters
Billing energy: E1 = V1(T1-T2)k
T1:Inlet
Control energy: E2 = V2 (T1-T2)k
T2:Outlet
T3 can be used for checking the measurement of
either inlet for outlet temperature, but T3 is not used
for calculation.
Mass: M1 = V1 (Kmass t1)
Mass: M2 = V2 (Kmass t2)
