Hey Ed, Does It Matter Where I Take My Supply Air Measurements for Discharge Air Temperature or Relevant Humidity?
In this edition of "Hey Ed", Ed discusses if it matters where you take your supply air measurements for discharge air temperature or relevant humidity
Hey Ed, does it matter where I take my supply air measurements for discharge air temperature or relevant humidity? It definitely makes a big difference where we’re gonna take that supplier temperature, when the air comes out of the top of the evaporator coil or if it's in an air handler and the fan is sucked in the air through, that air is gonna be turbulent, it’s not gonna be mixed well, so we wanna get half a dozen feet downstream at least or even better if we have a tape off and the air has an opportunity to mix and turn, that’s gonna give us the best reading that we can possibly take on that supply side of the system and that’s the way I see it.
