Uponor Taicang Production Factory

With Uponor Spectra metallic panel, energy is exchanged between surfaces and the surrounding areas by radiation and there is no air movement involved. The temperature of the water in the radiant panels is between 15°C and 18°C in cooling mode and between 35°C and 40°C in heating mode. The absence of radiators, fan coils or other cumbersome devices means complete freedom in terms of layout and furnishing. It allows all available space to be utilized to its full potential.

Using a DOAS In humid climate zones, with a mixing chamber and recirculation air is essential to save energy. The custom made DOAS used in this particular case, consists of three VSD fans for exhaust, recirculation and fresh air and a mixing chamber. This allows to control the CO₂ and the dew point of the internal space according to demand. The fresh airflow streams through a sensible heat exchanger and is mixed with part of the return air. After mixing, a pre-cooling coil, served by the shared chiller plant, followed by an evaporative cooling coil, served by direct expansion chiller, dehumidifies to a dew-point of 8 g/kg water content in the air. The condensing coil of the direct expansion chiller reheats the air flow. In order to control the sensible temperature of the supply air flow, a post-cooling coil, also served by the shared chiller plant, provides sensible temperature adjustments. Maintaining a dew point below 15˚C was the target to achieve perfect operating condition for radiant cooling.
