1. Power supply should be stable and reliable, transportation and communication should be convenient, and the natural environment should be clean;
2. Stay away from dust, lampblack, harmful gases, corrosiveness, flammability,
Explosive places (boiler room, parking lot, sewage treatment station, etc.). ); 3. Stay away from areas with flood and fire hazards (kitchens, residential areas, etc.). ); 4. Stay away from strong vibration sources and strong noise sources;
5. Avoid strong electromagnetic interference (radio and television towers, etc.). ). When the electromagnetic interference intensity is uncertain,
Need field measurement. The measured value exceeds the electromagnetic field interference intensity index specified in the national standard "Code for Design of Electronic Information System Computer Rooms" GB 50 174-2008 (when the radio interference frequency is 0. 15 ~ 1000 MHz, the radio interference field strength of the main computer room and the auxiliary area should not be greater than 126dB, and the magnetic field interferes with the environment. ), shielding measures should be taken; 6. The composition, area and environmental conditions of the electronic computer site conform to the "general computer site"
Code GB/T 2887-2000.
7. Stay away from the main transformer and distribution room and avoid the place where the main power cable passes;
8. The computer room should be built in the center of the building as far as possible to avoid being too long and beyond the transmission range.
Conditions leading to signal attenuation. If there are two or more buildings, the main computer room should be placed in a building with dense information points, and the optical fiber should be radiated from the main computer room to the sub-computer room of other buildings, and then the network cable or optical fiber should be laid from the sub-computer room to the information point or relay equipment, and the sub-computer room should be located in the center of the building as far as possible.
9. Keep a considerable distance from garbage rooms, kitchens and restaurants to prevent rodents;
Second, the location choice of the computer room in the building
1. The location of the computer room should avoid areas that are prone to water leakage, and should not be located at the lower level of water equipment. Please pay attention.
There are no water pipes around to prevent the water pipes from bursting and flooding the computer room; (Considering the problem of air conditioning water intake) 2. Avoid choosing the top floor, basement, building corners and other places that are prone to rain leakage, water seepage and lightning strike.
The unit is the computer room;
3. Deformation joints and expansion joints should not pass through the main engine room;
4. The main structure should be a column network with large span and large bay;
5. The clear height of the machine room should be based on the area size, cabinet height (generally 1.8 ~ 2.2m) and ventilation requirements (gas
The distance from the top of the cabinet to the ceiling required for mobile organization is generally 0.4~0.8m). The clear height is generally 2.7 ~ 3.0m Therefore, the height above the ground (generally 0.4~0.5m), the clear height of the machine room, the height of the top gas fire extinguishing and air supply and exhaust pipeline and the overlapping height of the pipeline should be considered. The distance between the bottom of the beam and the ground should not be less than 3.3m The minimum height is 4-4.5m.. ..
6. The host and outdoor unit of special air conditioner for computer room have requirements for height difference and distance, which is true.
When determining the location of the main engine room, the installation location of the outdoor unit of the special air conditioner for the engine room should be considered. The vertical position difference between indoor and outdoor units is ≤22m, and the horizontal distance of pipelines is ≤ 40m; The shorter the distance between refrigerant pipes, the better the refrigeration effect. 7. The bearing capacity of the computer room area should meet the requirements of the design code for computer and electronic rooms, and the live load of the main computer room should be 8 ~
10kN/m2, UPS live load 8 ~ 10kn/m2, battery room live load 16kN/m2. From the economic point of view, the main engine room should be selected in the low-rise part of the building;
8. In order to reduce the electromagnetic induction damage caused by lightning, the main engine room should be located in the center of low-rise buildings.
And try to stay away from the lightning protection downlead of the building or the column of the external wall structure (using the steel bar in the column as the lightning protection downlead) to avoid the downlead from damaging the electronic information equipment due to the strong magnetic field generated by the large current; 9. Facilitate the transportation of large-scale equipment such as refrigeration, air conditioning, UPS and large-scale information system equipment serving the computer room.
Lost. The transportation route should be as short as possible and the equipment handling channel should be wide enough.
10. Considering the structural load, lightning induction, outdoor air conditioning installation, equipment handling and other factors,
The computer room should be located on the second and third floors of the building or the middle floor of the podium. Although considering the structural load, lightning induction and equipment handling, it is beneficial to set the computer room on the first floor and basement. There are risks of floods, dust, pests and rats, as well as safety problems. If the building is a high-rise building, outdoor air conditioning cannot be installed downstairs, or for other reasons, it is impossible to build a computer room on the lower floor of the building, it is best to choose the floors below the highest floor, and it is best not to choose the top floor. Because the top insulation is difficult, it is also prone to water leakage accidents.
1 1. The power supply of the computer room is Class A, so as to ensure that the dual power supply enters the computer room with a margin.
12. Consider 24 46-inch LCD TV monitoring walls.
13. Consider outdoor air conditioners and new fans.
