U-Shaped air treatment arrangement in an air handling unit

An air handling unit comprising a U-shaped air treatment arrangement, which U-shaped air treatment arrangement extends between longitudinal walls, floor and ceiling of the air handling unit, thereby defining an air intake zone and an air outflow zone within the air handling unit, which U-shaped air treatment arrangement comprises,

• beginning at a first longitudinal wall of the air handling unit, a first secondary bypass wall, connected perpendicular to the first longitudinal wall,
• the first secondary bypass wall is connected in a perpendicular manner to a first primary air path wall running parallel to the first longitudinal wall,
• the first primary air path wall is connected via a first corner connection piece to a primary bypass wall which is positioned perpendicular to the first primary air path wall and distal from the first secondary bypass wall along the first primary air path wall,
• the primary bypass wall is connected via a second corner connection piece perpendicular to a second primary air path wall running parallel to the first primary air path wall and a second longitudinal wall of the air handling unit,
• the second primary air path wall is connected in a perpendicular manner to a second secondary bypass wall, which second secondary bypass wall is connected in a perpendicular manner to the second longitudinal wall,
• wherein, in conjunction with the floor and ceiling of the air handling unit, the afore-described U-shaped air treatment arrangement completely divides the air handling unit into an air intake zone and an air outflow zone, and wherein the bypass wall are equipped with bypass dampers, and optionally air filtration or air conditioning component(s), and the primary air path walls are equipped with air conditioning components and air filtration, and optionally face dampers.
