Fangyuan Tower located at Beijing in north China with cooling time more than 5 months every year. In their original cooling system, there are 4 chiller and 8 cooling towers. the cooling tower can not work with high efficiency during low flow, which means the chiller can not get enough cool capacity during partial load. Furthermore, the location of cooling tower is very specia with high wall around. the walls are 5 meters high, and one meter higher than the wind inlet of the fillers. The distance from the wind inlet to the walls are 3 meters of 2sides, and only 0.5 meters of the other 2 sides. The place is really bad for the wind flow of the cooling tower.
After seriouse on-site survey and evaluationm ACEC provide the customer with tailor made "all condition efficiency" system upgrade solution.
After the amendment, all the problems of Fangyuan Tower cooling system are solved with cooling approach reached 1.4℃ (design standard is 4℃, the actual operation condition is over 5℃ for most projects). the target for energy saving, water saving, intelligence management is all achieved - engergy saving for chiller is around 15%, energy saving for pump is around 50%, energy saving for fans are between 60-70%, which means 40000-50000 kwh per month power saving. The customer is really satisfided with the result.
Founded in 1988, Fordoo group, the member of Fordoo group Hongkong, is one of the most famous garment company in China. the company is loacted at Hudu industry garden Quangzhou Fujian with a area of more than 100 Mu and nearly 150,000 square meter's building area..
They use the ACEC cooling tower in their air-con system: type AC300T6N1G, cooling capacity 300*6m³/h. Compared with their original system, the energy consumption reduced 15%. Customer speak high of the stable cooling performance, intelligence and high efficiency manangement.
Shishi International Textile City, located at the north of Shishi Garment city, is one of the key construction project. The whole project occupied a area of more than 500 mu, with total building area 820,000 square meter. Thera are 4 fabric market and 5 business building, means 4 fuctional area - fabric market, businees office, general commercial center, logistic service.
Currently, the cooling system for all the areasare from ACEC with total capacity around 14200 m³/h.
The intelligence control management of ACEC system bring the benefit of easy management, high efficiency, low management cost, uniformed water distribution and low energy cost. The high quality service image gained the honor from construction party, the management team as weel as the owner.
Shishi Garment City is located at the busy street of Shishi city, cover the area of 1110 mu with building area of 600,000 squaremeters, and total investment reach 1 billion.
The cooling tower in the original system have the problems of uneven water distribution, suciton and overflow, which caused the bad result of chiller cooling. A area is taken as the pilot project upgraded by ACEC tower with high-efficiency intelligence manament. After upgraded, the cooling water approach reached 2.2℃. The chiller performance in the pilot area is increased a lot and the cooling result is much more better than the other area. At the same time, the energy consumption is generally decreased - 23% decrease for chiller, 20% decrease for fan and 50% decrease for pump.
As the result in pilot area is over the expectation, the upgrade for other area is also put onto agenda.
