Fan, pumps and controls

[John73]

Hi,
I have a problem with my consumption of fan pumps and controls which is around 5.4MWh.
I would like to know what IES take into account in this part?
How can I reduce this consumption?

Also, I set solar panel for my domestic hot water production, but I do not see where it appears in the result.

Regards

Hi this comes from the project Apache Systems, I expect it will mostly be from auxiliary energy (check the HVAC and DHW systems).

Vista defn:

Ap Sys fans/pumps/ctrls energy: Energy consumed by fans, pumps and controls within Apache Systems. Includes auxiliary energy, chiller heat rejection pump energy, and pump energy associated with DHW and solar water heating systems.

You were right.It come from auxiliary energy, we had an auxiliary energy value of 8.287w/m², I don't know what it means.
Can we do without any AEV?
Can you tell me what is the difference between AEV and SFPs?

Thank you

I think you'll find the answers to your questions in this manual (try the Apache Systems section, page 38):
