Right here you'll be able to see both equally in the values we calculated slide between vales shown within the table so we must execute a bilinear interpolation. To save time we’ll just use an internet calculator to learn that, link here (observe the video to learn the way to accomplish a bilinear interpolation).

Would seriously recognize your insight/strategies how i could get to the desired temp selection during the RM2.

Once you’ve adjusted the damper of all diffusers on the concentrate on airflow, go close to and measure all diffusers once more to see if their airflow is now acceptable (what you wish to obtain).
