This project is located in the Shanghai Bonded District in land parcel GSM1-3. To meet their internal demand, ICBC needs to build additional data center spaces on this site. It will have 2 phases where Phase 1 has 12,000 square meters of net computer hall space and an additional 6,000 square meters in Phase 2.
The data center was designed to comply with Uptime Institute’s Tier IV standards, according to the principles of reliability, simplicity, flexibility, scalability, and proportionality. It has a total of four floors with an average 6-meter floor height. Level 1 is for machine rooms and two wind tunnels designed for heat dissipation of machine rooms. Levels 2 to 4 are for computer halls. There are two units on each floor, totaling 6 units for the building. Managers and maintenance staff will enter the computer halls from the basement level via special elevators for security control. Visitors and materials suppliers will each have dedicated paths again for maximum security.
We designed the most innovative redundant cooling system for this project. The primary cooling is to be handled by a water-cooled chiller plant. An independent air-cooled plant will function as a backup. The water-cooled plant is chosen as the primary system due to operational efficiency. The water-cooled system will have 8 hours of makeup water for the cooling tower and chilled water storage in the cold loop to allow time for the air-cooled redundant system to respond. The air-cooled chiller plant will allow concurrent maintenance to be done on any part of the water-cooled system and vice versa. The air-cooled chiller system also saves precious project space. The inter-use of the air-cooled and water-cooled systems will truly enhance the cooling redundancy of the data center.
The base UPS technology required for ICBC is static, low voltage, double-conversion type UPS. The required battery support time at full UPS capacity is 15 minutes. This design requires that the UPS substations, UPS systems, and UPS batteries are on the same floor as the data halls. The load-bearing capacity of the battery room floors must be increased because of the weight of the batteries. The normal operating efficiency of this type of UPS system is 89%- 93%. We propose the following alternate UPS technologies that offer advantages over the base UPS technology.
