AHU- AIR FLOW RATE & COOLING CAPACITY

Hi, please let me know the below details. I need the chilled water type AHU and here is the unit details.
1. Air flow rate - 9795 cmh
2. Cooling capacity - 34.30 Kw
3. Water In / Out - 6 /12 Deg.C
4. On / Off Coil Temperature - 50.01 ºC DB / 40.00 ºC DB
5. Design Temperature - 50.0 Deg.C (Room Temperature)
When I sent an enquiry to the AHU supplier he informed me that based on the details (Air flow rate) given the cooling capacity will be 140.0 Kw.
I don't understand the reason behind this. Could you please let me know the concept of this?

regards,
giri
