Currently have a large UPS within a room that has poor ventilation.

I would like to propose to add an AC system within the room and tie it to the UPS to keep the UPS from overheating.

Since the UPS is always running and feeding life safety loads, I believe the UPS is a life safety load itself as well which will need to keep itself within the temperature ratings.

Tried to look for NFPA standards that could assist me with this suggestion and couldn't locate anything I would appreciate anybody's help on this.
 
The national electrical code requires all installations be done in accordance with the manufacturers instructions for listed devices. This is to be found in article 110 somewhere.

If the instructions that come with a listed UPS specify a maximum ambient temperature, you are not in compliance with the national electrical code if you allow the ambient temperature to that maximum.

I'm pretty sure that a UPS that is being used for life safety circuits is required to be listed.
 
HVAC systems typically don't need UPS power as long as they're on a generator that will start & take load fairly quickly and if the HVAC can tolerate a 15-30 second outage and restart. (If a 30 second HVAC outage is a problem, there are bigger issues than just heat removal.)

Can you improve the ventilation?

Standard UPSs are not designed or listed to carry life safety loads as related to Article 700 or 701.
