The Underfloor Air Distribution solution adopts the method of supplying the indoor lower part with the air-passed heat-exchanging process of an AHU for ventilation through ceiling or wall grills; as the air flows toward the ceiling, air-conditioning environment and air quality are favorably maintained indoors.
The pressure in the air-conditioning plenum is kept the same as indoor pressure, air is sent in the room by FTU equipped with a fan, and air volume and temperature are controlled by controlling the built-in blower in the FTU (built-in coil/heater) to respond to local load and for high energy efficiency
Air is sent in the room through floor blow-out holes by maintaining constant- pressure difference between the inside of plenum and room space. Constant-temperature air volume is transmitted through the same size of blow-out holes to the space where pressurized floor air-conditioning is done.
