I noticed that when parked, the airco fan sometimes switches on for long periods. Outside temperature was over 95°F. I've been amazed to feel that it blows quite fresh air, even 20 minutes after the engine -and the compressor I guess- was shut off. Is this normal?
V70 - A/C fan

It is part of a system they have to keep smells from forming in the AC system due to moisture and fungus forming. Letting the fan blow dries out the AC system.
If you're talking about the fan inside the car, then that's normal. It's to dry the condensation caused by using the A/C, which inhibits mould formation (smell) and corrosion (expensive part replacement).
It was still that way on my 2001 V70, the A/C fan comes on after we leave the car. It gives the normal condensate time to run down the walls into the drain. Then it kicks on the fan to dry it out.
