We normally install light commercial systems but have recently been asked to look into a couple of rooms in an industrial building which are not keeping to their designed temperature.
They run off a Air Handling Unit with a 300kW cooling coil working from an internal air intake of 30°C Summer and 18°C Winter.
Required Room Specs are:
Room 1:
20°C±2°C
45Pa
10 Air Changes
3.22m³/s
Room 2:
20°C±2°C
30Pa
16 Air Changes
2.57m³/s
Basically just want to know if the AHU is sufficient for what is required for each room?
If anyone can help, I'd appreciate it.
Please find drawing of the system below:

Well first off you need to know how much sensible cooling capacity you need for each room.
The quantity of air is known, so then you can calculate the supply temp of the air.
When you know de supply temp, you can calculate the cooling capacity of the AHU (sensible + latent)
If you dont have enought cooling capacity, i think the best thing to do is add capacity in the room itself, so that you dont have to dehumidify so much air.
