Hi,

I am classifying my 24/7 elec/comms rooms under G3.1.1 Exception b and therefore modeling them with System 3 - Constant volume packaged roof top air conditioner.

My question is as these spaces aren't really occupied but are 24/7, should the system a) be constant volume 24/7 and vary the temperature to meet the load in the space or b) cycle on/off to meet the load in the space.
Thanks
