Hello
In our new building from 2013, we have a central Vallox controlled residential ventilation system installed in the attic.
Last summer, however, it was the case that the system can only blow in air that has the same temperature as the outside air, so it became sometimes unbearably hot inside the house due to the sun shining through the windows. Of course, the controlled residential ventilation system can do nothing against that, after all, it is not an air conditioner...
Now I have seen a house where the controlled residential ventilation system was combined with an earth air heat exchanger, through which the air drawn in is cooled down/ somehwat warmed up in summer in the ground...
Has anyone retrofitted something like this before? Laying the pipe is less of a problem, rather that you have to run an air duct up the outside wall of the house to the intake opening of the system, which means again 8 meters of duct (east side of the house) that stands in the sun at least in the morning/forenoon and is heated up by the outside air during the day... A duct inside the building would accordingly involve considerable effort...
