Using the pipe sizing tables as instructed by the code books can lead to vastly oversized piping in some instances. I agree that if you use that procedure, it will work.
The code procedure does not seem to allow the deisgner to consider pressure losses for individual components in the...
The mechanical designer should give you data. At a minimum, Mfg, and Model# so that you do not have to read his mind.
Relating power consumption to performance is so varied that I would only use that kind of methodology for budgets and planning. For actual design and sizing of electrical, use...
Generally, I see unfiltered ventilation for electrical rooms with exhaust fan and intake louver (BDD on exhaust and motorized on intake). If dirty ventilation air is of concern then using a filtered supply fan and matching exhaust fan is a good way to go. The air flows can be matched, and the...
MagicJS,
Here in Tennessee, code officials interpert that to say that the free area of the duct and the free area of the louver are to conform to the SqIn/BTU rule.
ie. A 1000MBH boiler requiring 1 sqin/4000 btu will need 250 sqin area duct. If you use a std louver with ~ 75% free area...

I used to use HAP in DOS days (I'm dating myself)
Now I use Trace 700 for mostly load calculations, but The energy analysis is pretty easy and it does allow for doing side by side comparisions of different types of sysems.
The time needed to run calculations are inconsequental to the...

Does your apartment have occupied space above? How much exterior wall and window area do you have and what direction does it it face.
I digressed too far I suppose.... In that small portable window type A/C units are NOT designed to provide the comfort that most people expect...
MKimagin,
I hope that I can help...
- Remember that the HVAC system is a SYSTEM and even the space is part of it.
- The main purpose of the system (in cooling mode) is to remove the heat from the space in a way that keeps the occupants comfortable.
- Your theory that displacing the air...
