1, anti-static floor laying
In the technical construction of computer room engineering, the ground engineering of computer room is a very important part. Anti-static raised floor is generally used for the floor of computer room. The removable floor is convenient for connecting wires and cables, pipelines, maintenance and replacement of all equipment. The space under the raised floor can be used as a static pressure air supply bin, and the cold air sent by the air conditioner in the machine room is sent to the room and the cabinet of heating equipment through the raised floor with air outlet. Because the air outlet floor is interchangeable with the general raised floor, the air distribution in the machine room can be adjusted freely.
The floor surface under the raised floor generally needs moisture-proof treatment (such as washing moisture-proof paint, etc.). ). If the space under the raised floor is used as the air supply bin of the air conditioner in the computer room, the ground under the raised floor needs floor insulation treatment (such as Durkflex, etc.). ) to ensure that in the process of cold air supply, the ground will not be dewed due to the temperature difference between the ground and the cold air.
2, the roof wall decoration
The ceiling decoration is mostly used for the roof decoration of the computer room. The main functions of the ceiling of the computer room are as follows: the space from the ceiling to the ceiling is used as the static air supply or return air warehouse of the computer room, and ventilation pipes can be arranged; Install fixed lighting lamps, wires, various tuyeres and automatic fire detectors; Prevent dust from falling and so on. Metal aluminum ceiling is selected for the computer room, and the aluminum plate and its components should be light, fireproof, moisture-proof, sound-absorbing, dust-free and dust-free.
The purpose of interior wall decoration of computer room is to protect wall materials, ensure indoor use conditions and create a comfortable, beautiful and clean environment. The decorative effect of the interior wall is composed of three factors: texture, line and color. At present, the most common wall decoration for computer rooms is wall materials (such as aluminum-plastic plates and color steel plates), which are characterized by smooth surface, good air tightness, easy cleaning, no dust and no deformation. Wall base should be moistureproof, shielding, heat preservation and heat insulation.
3, partition decoration
In order to ensure that there are no columns in the computer room, the computer room buildings often adopt long-span structures. In order to meet the different requirements of different equipment in computer system for the environment and facilitate air conditioning control, dust control, noise control and computer room management, partition walls are often used to divide the space of large computer rooms into smaller functional areas. The partition wall should be light and thin, and it can also be sound and heat insulated.
Fireproof and burglarproof doors and windows are mostly used for doors and windows outside the computer room, while the doors and windows inside the computer room generally adopt frameless large glass doors, which not only ensures the safety of the computer room, but also ensures the transparent and bright effect in the computer room.
4.UPS uninterruptible power supply
The load of computer room is divided into main equipment load and auxiliary equipment load. The main equipment load refers to the computer and network system, computer external equipment and computer room monitoring system. This part of the power supply and distribution system is called "equipment power supply and distribution system", and its power supply quality requirements are very high. UPS uninterrupted power supply should be adopted to ensure the stability and reliability of power supply. Auxiliary equipment load refers to air conditioning equipment, power equipment, lighting equipment, test equipment, etc. Its power supply and distribution system is called "factory power supply and distribution system", and its power supply is directly supplied by mains electricity.
High-quality cables, trunking and sockets should be selected for electrical construction of the computer room. Sockets should be divided into waterproof sockets for mains supply, UPS and main equipment, and marked with easily identifiable signs. Lighting should choose the glare-free advanced lamps dedicated to the computer room.
The power supply and distribution system of computer room is the power guarantee for the safe operation of computer room. Computer rooms often use special power distribution cabinets to standardize the power supply and distribution system in order to ensure the safety and rationality of the power supply and distribution system in the computer room.
Generally, computer rooms are powered by mains electricity and generators, and generators are the main backup power supply, so the operating cost is low.
5. Air conditioning system
The task of air conditioning system in computer room is to ensure the continuous, stable and reliable operation of equipment in computer room. It is necessary to discharge the heat emitted by heat sources such as equipment in the computer room, maintain the constant temperature and humidity in the computer room, and control the dust content in the air in the computer room. Therefore, the air conditioning system in the computer room is required to have the ability of air supply, return air, heating, humidification, cooling, dehumidification and air purification.
Room air conditioning system is the most important equipment to ensure a good room environment, and precision air conditioning system with constant temperature and humidity should be adopted.
6. New exhaust system
The new exhaust system of the computer room has two main functions: one is to provide enough fresh air for the computer room and create a good working environment for the staff; Secondly, keep the positive pressure difference outside the computer room, avoid dust entering and ensure the better cleanliness of the computer room. The air distribution form of computer room should be considered in combination with the requirements of computer system and building conditions. The position of air duct and air outlet of the new exhaust system should be reasonably arranged with the air conditioning system and indoor structure. Its air volume depends on the air supply of the air conditioner.
7. Grounding system
Computer room grounding system is a comprehensive information processing project involving many aspects, and it is an important content in computer room construction. Grounding system is one of the key issues to measure the quality of computer room construction. There are generally four grounding methods for computer rooms: AC working place, safety protection place, DC working place and lightning protection place.
Computer room grounding should pay attention to two points:
(1) Signal system and power supply system, high-voltage system and low-voltage system should not adopt * * * grounding loop.
(2) The grounding of sensitive circuits should be isolated or shielded separately to prevent interference caused by grounding backflow and electrostatic induction. The comprehensive grounding scheme should be adopted for the grounding of the machine room, and the comprehensive grounding resistance should be less than 1 ohm.
8. Lightning protection system
The lightning in the computer room can be divided into direct lightning and inductive lightning. The protection of direct lightning is mainly accomplished by lightning rods installed in buildings; The lightning protection of computer room (including power supply system and weak current information system) is mainly to prevent lightning surge caused by induced lightning and overvoltage caused by other reasons.
9, monitoring system
The scale of CCTV monitoring system in computer room is not large, but it is essential to establish the security mechanism in computer room. It can monitor and record any event in the computer room 24 hours a day.
10, access control system
The access control system of computer room mostly adopts non-contact intelligent IC card integrated management system. The system can flexibly and conveniently specify the personnel, time and authority to enter the computer room, prevent the damage caused by human factors and ensure the safety of the computer room.
1 1, water leakage detection system
The main sources of water damage in the computer room are: water leakage on the roof of the computer room; The ground of the machine room is leaking due to the blockage of the upper and lower water pipes; The drainage pipe of air conditioning system is improperly designed or damaged and leaks; Poor heat preservation of air conditioning system forms condensed water. The flood in the computer room affects the normal operation of the equipment in the computer room and even paralyzes the operation of the computer room. Therefore, the leakage detection of computer room is one of the important contents of computer room construction and daily operation management. Besides paying attention to water hazards during construction, a water leakage detection system should also be installed.
12, computer room environment and power equipment monitoring system
With the continuous improvement of social informatization, there are more and more computer systems in the computer room, and more and more environmental equipment in the computer room. Environmental equipment in the computer room (such as power supply and distribution system, UPS power supply, air conditioning, fire protection system, security system, etc.). ) must always provide a normal operating environment for the computer system. Therefore, it is particularly important to monitor the electrical equipment and environment of the computer room.
Computer room environment and power equipment monitoring system mainly monitors the running state, temperature, humidity, cleanliness, voltage, current, frequency of power supply, switching state of power distribution system, leakage detection system and other historical data of computer room equipment (such as power supply and distribution system, UPS power supply, lightning arrester, air conditioner, fire protection system, security access control system, etc.). ) and record the historical data, so as to realize the management functions of telemetry, remote communication, remote control and remote adjustment of the computer room.
13, fire protection system
The engine room should be equipped with a gas fire extinguishing system, and the gas cylinder room should be located outside the engine room, adopting a pipe network structure, and the nozzle should be located on the ceiling. The fire alarm system consists of fire control box, smoke sensor and temperature sensor.
The fire fighting system in the computer room should adopt gas fire fighting system, and the common gases are heptafluoropropane and SDE.
14, shielding system
Computer room shielding is mainly to prevent all kinds of electromagnetic interference from damaging the equipment and signals in the computer room. There are two common types: metal mesh shielding and metal plate shielding. According to the different requirements of the computer room for shielding effect and the different frequencies and frequency bands of shielding, the materials and construction methods of shielding system are selected, and the requirements of various indicators are strictly implemented in accordance with the national "Code" standards.
