Technical room boundary construction, air source heat pump suction

I agree with you and have already filed the idea away and thank you for the clarification.

Now to the question; are there air heat pumps where the intake and the blower are only on one side?

That is certainly feasible with appropriate piping, it just doesn't make sense

We have it like this. Works very well so far.

Ok.

What ideas would you suggest if the air heat pump is planned in the technical room in the corner, but a wall is directly adjacent to the neighbor's garage wall?

Would you have a photo for better viewing?

How much space does the casing require?

Under no circumstances should the openings be directed towards the neighbor. We have that too, but with a 6m distance, you can no longer hear anything, etc.
