Under Floor Air Distribution System (UFAD)

Schneider Electric India Pvt Ltd offers Under Floor Air Distribution (UFAD) System. UFAD reduces energy consumption by over 20% compared to traditional overhead systems thanks to: lower fan pressures required to deliver air in a room; lower inlet temperature because air is supplied close to occupants and not from the ceiling; and efficient supply/return air flows that prevent freshly supplied air to be partially taken in by the suction fans. The increased well-being of office occupants translates in a more productive working environment: there is no chance for short cycling of the supply air. The natural convective flow activated by the human body heat moves the conditioned air up, pulling CO2 and humidity towards the return plenum. Unlike overhead systems, UFAD system air is always supplied at the comfort temperature, without high-speed air jets; a closer temperature control can be obtained by installing air boosters in separate rooms or in areas exposed to solar radiation. The system devices are integrated in the modular access floor without the use of ductworks, in this way they can be easily moved to accommodate layout modifications. The height of each floor can be reduced by 10%: this means for example that a 40 m high building can have 11 floors instead of 10; the access floor plenum is not only used to host air conditioning but also other infrastructures like electrical and hydraulic systems. No need of building dedicated ductworks since the ceiling and floor plenums are used as air ducts. The system design and construction is faster: 40% time is saved compared to traditional solution.
