[Equest-users] why pump consume less energy

[周志仁]

Dear all

         My proposed model consume much less pump energy which is less than
1% of the total energy. There are 10 chiller and 10 pumps(all are VSD) in
the proposed. The figure below shows the breakdown of total energy
consumption, the pump is very low. The pump setting is shown in the second
figure below. 

Why the loop head is given in the SIM file as shown in the third figure
below? Why the pump consume little energy? Can anyone tell me the reason?
Thanks a lot. 

 

 
Yours arron
