Hello, we are currently in the construction planning phase for our single-family house. We are getting the Alpha Innotec KHZ60 (heat pump + integrated controlled residential ventilation). The fresh air supply for the ventilation module has now been placed on the side of the front door lintel in the exterior wall, so that it is about 2.30m above the ground level.
However, the supply and exhaust openings of the heat pump (system is located in the utility room in the basement) are to be realized by means of wall penetrations and light wells. For the exhaust air, I only see the problem of possible dirt on the plaster of the outer wall above the air outlet light well. But for the supply air or the supply air light well, I have read that these very often attract dust, dirt, insects, snow, etc., and thus regularly clog the filters of the intake chamber, resulting in high maintenance costs. In a construction diary, a complete tight ice layer had also formed on the weather protection grille of the light well due to frozen sleet.
What do you think about this? Is such a regulation of the supply air via a light well acceptable? I see the aforementioned open issues and, in turn, it would be my responsibility to take appropriate protective measures (protective plates, plantings, etc. around the light well). Could the supply air of the heat pump not be placed next to the supply air of the controlled residential ventilation?
