ᐅ Is it possible to install air conditioning as an upgrade if a mechanical ventilation system with heat recovery is already installed?

Hello,
we live in a KfW55 house with a controlled mechanical ventilation system. Since it gets too warm for me in the summer, I would now like to add air conditioning units.
I am planning a total of four units: in the three bedrooms upstairs and in the open living, dining, and kitchen area on the ground floor.
I have looked at units from Gree and would choose 2.7 kW units for the upstairs rooms and a 5.3 kW unit for the ground floor, based on the room sizes.
Now to the main question:
Does it make sense to install air conditioning if we already have a controlled mechanical ventilation system? Do the air conditioning units generally need to be sized larger because the ventilation system removes the cool air too quickly? Or does the controlled mechanical ventilation system prevent the rooms from cooling down effectively in the first place?

You just have to do the math. My office, with its 11m² (118 ft²), has almost 2 kW cooling load ...Let me repeat the question: how does this calculation work? Is it something practical for everyday life or more like a heating load calculation that models extreme situations?
