Heat Recovery Problems

[IrinaB]

Hi all,

I am trying hard to get the amount of heat recovered from the heating system joint with ventilations system in a passive house. In Apache System in UK NCM system type i set that it is central heating with air distribution (exactly how i plan to do it) but then in heating system option there is no heat recovery indicator, it is present just in ventilation system. I set the efficiency and type of the HR heat ecxhanger, but i still do not get heat recovery curve in the result of my simulations. It is a residential house and cooling does not exist there.

Can someone help me with this task? I already tryed different options but still do not get it.

Regards,
Irina

think this is a duplicate but will ask again here...

Do you have ApacheSim or only the free SBEM? Will effect the answer I fumble my way into.

Yes, thisi is the same question...

Yes, i think i have ApacheSim ... at least it is written Apache, thermal calculation and simulation.
