How centrifugal scroll blowers convert kinetic velocity into high static air pressure

Portable climate devices like the EcoFlow Wave 2 must force air through extremely tight internal channels, narrow cooling coils, and long exhaust ducting. Standard axial fans, like the ones found in computer desktop coolers, fail completely in these environments because they push air straight parallel to the axis and lack the force required to overcome physical air resistance.

To conquer this, portable air conditioners utilize Centrifugal Blowers housed inside specialized Scroll Casings.Inside the blower, air is drawn into the center of a spinning wheel fitted with curved blades, which fling the air outward at high velocity via centrifugal force. As the high-speed air enters the expanding spiral shape of the surrounding scroll casing, the physical geometry of the housing forces the air to slow down.

According to fluid dynamics, this controlled deceleration converts the kinetic velocity of the air directly into high static air pressure. This pressure allows the unit to punch a steady stream of conditioned air through restrictive ducts and tight coils with maximum efficiency.
