AIR MIX SELECTION
AIR MIX SELECTION
(OP)
Hello everyone,
I have the following problem, outside air x conditions and its required 90% return air and 10% outside air to heat a building.
Is there a rule of thumb on what conditions to consider for indoor air( return) to calculate the mix?
I need to determine the BTU/hr required and need a practical method to handle air mixes.
Thank you

Check thread403-299263: Paint Room Dehumidification for the procedure and download Psychro07.zip from http://www.hvacware.net/engrproj.html. The fourth worksheet is about mixing calculations.

I see the calculator and its easy to use when you have both air stream conditions.
The problem is when you dont have the return air measurements, I suppose we have to assume these conditions but Im not sure.
Am I wrong?
