Or you install the necessary cooling coil -which capacity is unknown for the moment - but estimated on +/- 10 to 12 kW with +/- 600 l/s air flow or you install the max needed ventilation for a proper ventilation of 150 l/s and a matching coil of +/- 3 kW which will not cool enough.

Or your first flow of 360 l/s and a 5 to 6 kW coil which will serve well 80 to 90% of the year.
The max load is only for a few days/year.
Important: ground coil to pre-cool, you will need certainly a summer bypass if you expect excess heat.
