k*****n Extract Hoods

Post by RossThompson87 »

Hi,

I was just wandering how people approach entering k*****n extract hoods into DSM simulations.

Can they be ignored as their use is intermittent and dependent on a specific activity?

My preference would be to enter them as local exhaust. However obtaining data for the flow rates and specific fan powers never seems to be straight forward. Particularly if they are made by companies that generally only deal in k*****n appliances.

By default IES will assume an SFP of 0.4 W/l/s which seems very generous.

P.S.

I wanted the post to read "K. I. T. C. H. E. N" but apparently that has been censored!

Profanity filters are great :lol: (I was trying to figure out what exotic swear word you were using to vent your anger before I opened the full message!)

Anyway, I think hood extract sits under the definition of "process load" and should therefore be ignored.

I can't believe someone legitimately wanted to write kitch.en!

On the question we can define additional exhaust at room level as you know but there's no way to schedule when it operates (other than via the NCM Activity) so I think you would be unfairly penalised by it, I can't say for sure if you should be including for this or not though.
