ᐅ Preparation for possible attic ventilation or air conditioning

Hello,
we are currently renovating our new home (existing property) and are planning to convert the attic into living space in the medium term, most likely setting up two children's bedrooms there. Over the past few weeks, I have noticed that the attic gets quite warm.
We will properly insulate the roof, but if that is not enough, we might consider installing an air conditioning system later on.
Therefore, my questions are: What should I prepare now to make adding an air conditioning system easier in the future? I was thinking about a separate electrical circuit (possibly even a three-phase power supply). Does it also make sense to install larger conduits now to later run the ducts for cold air without having to open the walls again or do similar work?

Thanks for your opinions or even better, your experiences!

Regards

In my opinion, the drainage of condensate is one of the biggest challenges, especially when retrofitting. It is not exactly straightforward to install a pipe with a continuous slope from the indoor unit to the nearest drain pipe in an existing building.

We didn’t prepare separately but installed everything correctly right away. As a tip: the condensate drain is really the biggest issue! Be sure to include drain pipes at the appropriate locations. We used “self-closing adapters” where the hose connects. Never fix the condensate drain hose permanently in places like the screed, as it can get clogged. We routed all hoses into the ceilings so they are accessible in case of maintenance. Proper slope is also important. The pumps make noise, which you especially want to avoid in bedrooms. The unit itself is much quieter.

Do modern appliances evaporate the condensate for greater efficiency, or is that a misunderstanding?

Thank you for your experiences, suggestions, and tips!
One more question regarding the power supply: Does such a split unit require a three-phase connection, or is a 16A single-phase supply sufficient?

Not the common modern split systems, regardless of the design of the indoor unit
