PROFESSIONAL DATA CENTER COMPUTER ROOM CONSTRUCTION

The IDC data center room construction project is not just a decoration project. More importantly, it is a comprehensive project that integrates multiple disciplines and fields such as electrical engineering, electronics, architectural decoration, aesthetics, HVAC purification, computer, weak current control, and fire protection, and involves professional technologies such as computer network engineering and PDS engineering.

4. Fire protection in the computer room
1. Gas fire protection without pipeline network
The cabinet-type HFC-227ea gas fire extinguishing device can be connected to the fire control center and driven by the fire alarm and fire extinguishing controller to implement automatic fire extinguishing. The device does not require a dedicated equipment room, and the entire set of fire extinguishing equipment is within the protection zone. When a fire occurs, this device can automatically spray medicine directly into the protected area, which is convenient and quick. One system is set up in one protected area, and several devices can be used together to protect a larger area.

The lightning protection grounding system is an important subsystem for the protection of weak current precision equipment and computer rooms. It is mainly composed of lightning receiving devices, down conductors, grounding wires, grounding bodies (levels), grounding devices, grounding grids, and grounding resistors.

(2) Down conductor: A conductor used to conduct lightning current from the lightning rod to the grounding device.
(4) Grounding electrode: A metal conductor buried in the soil and in direct contact with the earth is called a grounding electrode. It is divided into vertical grounding electrodes and horizontal grounding electrodes.
(6) Grounding grid: A mesh grounding device composed of vertical and horizontal grounding electrodes with the functions of current discharge and voltage equalization.
6. Fresh air in the computer room
According to the installation method, the fresh air system can be divided into ducted fresh air system (central fresh air) and ductless fresh air system. Among them, the ducted fresh air system is mainly composed of three parts: fan, duct and air outlet, which are mainly divided into two types: ceiling full heat exchange fresh air fan and axial flow fan; while the ductless fresh air system is mainly divided into cabinet fresh air fan and wall-mounted fresh air fan. According to different ventilation principles, fresh air systems can be divided into two categories: one-way flow and two-way flow.
When designing the load-bearing capacity of a computer room, if you want to comply with computer room specifications, you should consider making scattered load-bearing brackets under the cabinets, and doubling the contact area of the bottom of the load-bearing brackets to disperse the load-bearing capacity of the floor. When the weight of equipment such as cabinets, air conditioners, UPS, etc. is large and exceeds the floor load, in order to ensure the structural safety of the building itself and meet the general computer room seismic requirements, you need to make load-bearing scattered load frames for the cabinets, air conditioners, UPS battery cabinets and precision air conditioners. The scattered load-bearing brackets can disperse the load-bearing capacity of the floor to meet the design value requirements of the floor ground bearing capacity.

9. Equipment Room Lighting
Emergency lighting ensures that personnel can handle emergencies and evacuate safely and quickly along the passage to the exit or emergency exit. The illumination is greater than 50LUX, and UPS is used to power some lamps. The glare limit level is required to reach Level I.
1. General lighting
The original lighting in the computer room was remodeled according to the cabinet layout, and the lighting rows were arranged directly above the sightseeing walkway and column walkway.

Emergency lighting, also known as accident lighting, is the lighting provided when normal lighting is extinguished due to a fault or power outage. According to the requirements of the bidding documents: the illumination of the passageway to the exit or emergency exit is greater than 50LUX, and other parts refer to the relevant standards: the measured illumination at 0.8 meters from the ground in the main engine room and the recorded media storage room is not less than 10LUX.
10. Construction Goals
All system designs should be planned uniformly during construction. Based on national standards and relevant standards promulgated by the state, including various construction, computer room design standards, power and electrical security standards, we adhere to the principle of unified standards, thus laying the foundation for future business development and equipment capacity expansion.

Adopt advanced and mature technologies and equipment to meet current business needs and take into account future business development needs. Use advanced technologies, equipment and materials as much as possible to adapt to the needs of high-speed data transmission, so that the entire system can maintain technological advancement for a period of time and have good development potential to adapt to future business development and technological advancement needs.
High reliability design standards should be adopted for each system. It should be able to complete the specified functions under existing conditions and within the specified time; it should be able to work reliably and stably over a long period of time; and it should have reasonable redundancy and disaster backup capabilities to provide basic environmental facilities that match the high reliability target requirements of information application systems.
There should be a complete security strategy and reliable security measures to ensure the security of the basic environment of the information room user operating system. Take effective measures in fire prevention, waterproofing, theft prevention, grounding, lightning protection, electromagnetic interference protection, noise reduction, etc., and consider special technical measures such as the ground's load-bearing capacity.

Each system should have a strong manageability logic of centralized management plus distributed implementation.

Each system should have the capability of sustainable development and greater flexibility in the system.
A good working environment should be provided in the computer room. First of all, keep the air fresh and the temperature and humidity in line with national standards. At the same time, it is necessary to ensure that the noise complies with relevant national regulations.
11. Construction Principles
We adopt advanced data channel management, energy conservation and environmental protection and other management methods, and fully consider the interfaces and supporting systems of integrated wiring, power transformation, computer network and other systems, so that the computer room system has a certain degree of advancement and ensures the long-term and efficient operation of the computer room system.
We use high-quality materials, superior equipment and standardized construction technology, especially the anti-interference and rapid replenishment capabilities in unexpected situations, to ensure that every link is safe and reliable.
The design is strictly in accordance with the relevant standards of the national technical site, the drawings and documents are standardized and complete, and the common symbols and marks of the national standard are adopted, striving for universality, adjustability, easy maintenance, and with detailed documentation.
After implementation, the computer room is rationally divided and the process flow is simple; the system configuration is thoughtful, comprehensive, convenient and flexible, and different grades of materials are selected according to the requirements of each functional area. On the basis of fully considering the perfect functions of the electronic computer room system, its cost performance is optimized.
This system should not only support the existing system, but also leave sufficient room for expansion in terms of spatial layout, system power grid capacity, network equipment ports, etc., to facilitate further development of the system and adapt to future system upgrades.
