100% Outside Air System
100% Outside Air System
(OP)
I have a case where we will build a building that requires 100% OA for process purposes. There is a requirement for 2 air changes per hour. The building is a typical metal building used in the US, and will be insulated. There will be about 10 people in the building normally, and some industrial equipment. My question is, based on the OA requirement, how does the equipment (internal) and external load impact the cooling load calculation? All air will be exhausted, so heat generated from these loads will be as well. Would these loads be added to the cooling load calculated for the Outside air or not?

The bottom line is heat energy and capacity.
Your air enters at a certain temperature having been cooled and is then heated up by the radiant heat and alos by the people and the machines. That will raise the air temp to some temperature which you can calculate before it is exhausted out of the building.
Hence if you get the air distribution wrong, some people will freeze and others will or could get very hot if your machines emit a lot of heat.

A temperature that you can run a motor might not be the same to maintain an operator comfortable.
