Hello,
We have built a passive house and moved in around Easter. Unfortunately, we had an almost unbearable summer. Despite shading, we had almost continuously over 26 degrees in the house, even at night. We have a ventilation system from Paul (Novus 450) with an active brine air precooling. The ventilation is not yet properly adjusted; it currently runs at about 30% higher volume flow than necessary. The problem now is that no matter what the temperature of the supply air is, about 0.5 degrees less than the room temperature arrives at the valves. Even with active bypass and a lowering of the supply air to 16 degrees, we have 22.9 degrees (our current room temperature without additional heating is 23.5 degrees). The installer measured the values and said not optimal but within limits. However, I cannot believe that since we sweat night after night and don't even get cool air into the house at night? Has anyone had a similar experience? Thanks for any help...
Regards,
Thorsten
