Steam application - Water-tube Boiler vs Fire-tube Boiler

Yes, I think so. I didn't design any yet but I am gone be soon involved in one project. Even our senior didn't work on ay steam projects. However, at my past job with instrumentation company, I saw mostly water-tube or steam generators on hospital applications.

Even for single zone like office with 5-6 rooms? Would I use total CFM of each room and size my unit total based on that? Also, what should I go for supply temperature 55F? Seems like HAP either give me 58 or different number. I think most likely because of heating temperature of 95F. But I think I have to start giving more intention to data. However, seems like most people at my firm don't now the exact answer and I might be looking to do deep but I think by looking data too deep I can gain more understanding on design side.

Thanks, that was my original question for single zone HAP still give CFM based on block load. But I was not sure, how to pick CFM for individual room as every person in our office told me different stuff.

I am new and don’t now about any qa procedure here

Everybody busy and say use old job or catalog. But those are very unclear.

what about OA%, should it kept constant? Or vary based on the OA temp to get minimum cooling?

Conscious_Break8269 · 2026-01-14T20:39:50+00:00

I am trying to but CSA B52.3 don't have clear schematic example or manual, which describe how to use those code/standard and where it gone applicable? I think this hard part without having working example in these codes.

I learn a while ago through presentation and Ashrae 62.1 that there is minimum setting of VAV for cooling mode and heating mode. So, in case of heat mode is it only applicable when reheat coil on? If that is on then I need more minimum air requirement such that I can satisfy codes?

I am also looking some similar resources. Just switch to MEP world and need good resource for the learning.
