Hard angles in this fairly standard climate battery tubing layout mean that airflow is heavily unbalanced. This system still performs, but a majority of the tubing is doing very little work. Imagine how a well-designed tubing layout would function! https://images.squarespace-cdn.com/content/v1/5f97074e11067d7587b2d840/a255c03c-e8f7-47c3-a0bc-096626c784d0/Top+Edge+Volumetric+-+Velocity+%40+15+Seconds+-+9m_s+Cap.png The Condensate Blog - Climate Battery Design Comparison - Why Design Matters - Make it stand out The Atmos Version 1.2 design reveals a more balanced airflow distribution with a flow rate of 3,500 CFM at 0.33” static pressure with our specified fans.
