Lets assume the following in a single room:
Sensible gain: 20662
latent gain: 1662
total: 22324
I am looking at a mr slim type rated at 24,000 btu unit with the following:
sensible capacity: 14800 btuh
latent capacity: 9400 btuh
I see the total for the unit is greater than the total heat gain...
If I have a Oven Room (110 sqft) with one louver for exhausting air with a propellar fan and one louver for pulling in outside air.
What method do I use to size the fan (CFM-wise) in order to maintain my oven room to equal outdoor temperatures?
Lets just assume I'm generating 20000 btu/h from...

Ive been looking at a few sites and Im not sure if they are all pretty much the same thing or theres a certain one that is better than others.
thanks
Does anyone know of any company/seminars that offer quality electrical design for buildings? I am trying to get into the field and wanted to see if there is a good place to start.
Thanks in advance.
If a building has a controls system which ties multiple thermostats to a single air handler (Trane Tracker).
The room setpoints for Heating is set to 68, all of the room temperatures are below 68 as reported by the Trane Tracker system, BUT the system is calling for cooling. Is this simply a...
Im trying to size a 100% OA unit. What is the typical way to do this? I always thought you would pick the point where the humidity ratio was the highest for that region. Is this the correct way?
Say I had a split system serving 2 rooms, one being exterior and one being interior space. I understand you should not group these two together on the same zone bc they have different cooling loads. But why can you just not have more air flowing to the exterior room and have the damper in the...
