Data center computer room construction needs to pay attention to these problems
Data center computer room construction needs to pay attention to the major issues, we all know that the body is the capital of the revolution. With the development of modern network, everyone will deal with the data center computer room more or less, in fact, because we live and work for a long time. In modern buildings, the emergence of new concepts such as sick building syndrome is inevitable. According to the World Health Organization's sick building syndrome is the symptoms caused by the use of buildings, it also has many complications, then whether our data center computer room construction should circumvent similar problems.
In recent years, some experts and scholars have suggested that people's dissatisfaction with indoor odors should also be included in the sick building syndrome. A large number of surveys and analysis show that people spend about 90% of their time indoors, and poor indoor air quality is the main cause of sick building syndrome. Most of the devices in computers and program-controlled rooms are electronic devices such as computer systems and switch systems.
In order to ensure that the computer system and the switch system work stably and reliably, reduce faults, prolong service life and improve work efficiency, a good environment must be created. Therefore, when the machine room is built, it must pay enough attention to the equipment room environment. It is understood that in the computer network room that has been installed at present, some machines work very unstable and have a direct relationship with poor environmental conditions. The new air exhaust system in the engine room has two main functions: one provides enough fresh air to the machine room to create a good working environment for the staff; the other maintains the positive pressure difference of the machine room to avoid dust entering, ensuring that the machine room has better Cleanliness.
The airflow organization in the equipment room should be considered in combination with computer system requirements and building conditions. The position of the duct and tuyere of the new exhaust system should be properly arranged in accordance with the air conditioning system and the indoor structure. The air volume depends on the amount of airflow supplied by the air conditioner.
At the same time of exhausting the air, we also need to focus on the lightning protection of the equipment room. It is divided into direct lightning and inductive lightning protection. The protection against direct lightning strikes is mainly done by the lightning rod installed in the building; the lightning protection of the equipment room includes the power supply system of the equipment room and the lightning protection of the weak electricity information system. The work is mainly to prevent lightning surge caused by inductive lightning and overvoltage caused by other causes.
More than 95% of the lightning damage of computer room equipment is caused by inductive lightning strikes. The main ways are:
The outdoor transmission line is subjected to the electromagnetic overvoltage caused by lightning lightning to counter the industrial overvoltage. The lightning arrester shall be installed on all external lines (communication, power supply, etc. using metal transmission media) to enter the equipment port in the equipment room, and use 1 to 3 lightning protection as the case may be.
The grounding system is an important part of the equipment room environment. It not only directly affects the communication quality of the communication equipment in the equipment room and the normal operation of the power supply system of the equipment room, but also protects personal safety and equipment safety. The grounding system consists of a grounding body, a grounding lead-in wire, a grounding wire or a grounding tandem row, and grounding wiring. The resistance of the grounding system is mainly determined by the soil resistance near the grounding body.
