Why is it essential to keep the angle of transformation pieces below a certain threshold?

Keeping the angle of transformation pieces below a certain threshold is essential primarily to minimize pressure losses in air distribution systems. When the airflow encounters sharp bends or excessive angles, it creates turbulence and resistance, which can impede the flow of air. This pressure loss can lead to decreased efficiency in heating or cooling systems, resulting in higher energy consumption and reduced comfort levels in occupied spaces.

Maintaining a smooth transition in the ductwork not only helps preserve the intended airflow but also supports the overall performance of the HVAC system. When the angles are kept within recommended limits, it allows for optimal airflow, ensuring that conditioned air reaches its intended destination without significant losses. This focus on pressure management is critical for the design and operation of effective air distribution systems.
