As a result of growing Chinese urbanization, special demands are being placed on construction projects to reduce energy consumption and pollution. Recently, HVAC-system provider Danfoss has won more orders for Shanghai Tower, including an order for 6,700 valves to control the cooling and heating systems in the 632-meter high building. It is the highest number of these valves that Danfoss has ever delivered to a single building.

Awards

Shanghai Tower has already earned the American Leadership in Energy and Environmental Design gold certification and the Chinese 'Three-star green building' award, which is the highest standard that can be achieved in China.

The 6,700 control valves in Shanghai Tower will automatically secure precise control and the right balancing of the water flow in the kilometer-long pipework. This also means that people on the top floor get the temperature they want quickly, regardless of the temperatures preferred on the lower floors.

“More than 50% of the building’s energy consumption comes from the heating, ventilation and air-conditioning system. By using our control valves, 20% of this energy consumption can be saved, which means a lot to the owner,” says Lv Guosheng, Danfoss sales engineer, who is in charge of the project.

Variable speed drives

For the heating and cooling systems, Danfoss will also deliver 660 variable speed drives that will ensure that the pumps, compressors, and fans never run faster than is necessary to secure the right temperature. This will contribute to additional savings of 20-40% compared to running without this technology. Moreover, energy-efficiency in the air-conditioning system will be boosted by pressure transmitters and filter driers from Danfoss.

Previously, Danfoss has also delivered products to the highest building in world, Burj Khalifa in Dubai, as well as other significant constructions globally such as the Empire State Building in New York, the Kremlin Palace in Moscow and the Carpe Diem Tower in Paris.
