Uponor Shanghai office, China
On the other hand, Uponor PEX-a pipe underfloor heating and invisible supply air duct are also installed in the whole office. DOAS (dedicated outdoor air system) in parallel with radiant cooling has been also applied. Cooling load of the conditioned space has been split into sensible load (36kW) and latent load (12kW). 100% of the internal latent load and 30% of the internal sensible load are covered by the DOAS. The remaining sensible load is covered by the Uponor radiant cooling system and controlled by Uponor Smatrix Wave Plus individual room controller. It constantly monitors changes in conditions inside and outside the building. By intelligently adjusting and adapting, Uponor Smatrix ensures that just the right amount of energy is used at just the right time.
This is already the third project we using DOAS in parallel with Uponor Radiant heating and cooling system in Asia region. With a combination with DOAS used in the case, it consists of two VSD fans for exhaust, fresh air and a mixing chamber. It allows maintaining healthy CO₂ levels at the same time to provide fresh air to the office space.
