Ground engineering of computer room

In the technical construction of computer room engineering, the ground engineering of the computer room is a very important component. The floor of the computer room is generally made of anti-static raised flooring. The raised floor has the characteristic of being detachable, so the connection of all equipment's wires and cables, pipeline connection, and maintenance replacement are very convenient.

The ground surface under the raised floor generally needs to be treated with moisture-proof measures (such as applying moisture-proof paint, etc.). If the space under the raised floor is used as an air conditioning supply air duct for the computer room, the ground under the raised floor also needs to be insulated with a floor.

Computer room ceiling project

The ceiling decoration of computer rooms often adopts the suspended ceiling method. The main function of the suspended ceiling in the computer room is to serve as a static pressure supply or return air duct in the space above the ceiling, and to arrange ventilation ducts; Install fixed lighting fixtures, wiring, various air vents, and automatic fire detectors; Prevent dust from falling, etc. The computer room should choose a metal aluminum ceiling, and the aluminum plate and its components should have lightweight, fire-resistant, moisture-proof, sound-absorbing, dust-free, and dust-free properties.

Computer room wall engineering

The purpose of interior wall decoration in the computer room is to protect the wall materials, ensure indoor usage conditions, and create a comfortable, beautiful, and clean environment. The decorative effect of interior walls is composed of three factors: texture, lines, and color. At present, the most common wall decoration in computer rooms is the use of wall mounted materials such as aluminum-plastic panels and color steel plates, which have the characteristics of smooth surface, good air tightness, easy cleaning, no dust, and no deformation.

The base layer of the wall decoration should be treated with moisture-proof, shielding, and thermal insulation.

Computer room partition project

In order to ensure that there are no internal columns in the computer room, large-span structures are often used in the computer room building. In order to meet the different environmental requirements of different devices in computer systems and facilitate air conditioning control, dust control, noise control, and computer room management, partition walls are often used to divide large computer room spaces into smaller functional areas. The partition wall should be both light and thin, and also provide sound and heat insulation.

Fire resistant and anti-theft doors and windows are commonly used for the exterior doors and windows of the computer room, while frameless large glass doors and windows are generally used for the interior doors and windows of the computer room. This not only ensures the safety of the computer room, but also provides a transparent and bright effect inside the computer room.

Computer room power distribution engineering

The load of the computer room is designed according to the first level power supply load.

The computer room load is divided into main equipment load and auxiliary equipment load. The main equipment load refers to the computer and network system, external computer equipment, and computer room monitoring system. This part of the power supply and distribution system is called'Equipment power supply and distribution system'The power supply quality requirements are very high and should be adoptedUPSUninterrupted power supply is used to ensure the stability and reliability of power supply. Auxiliary equipment load refers to air conditioning equipment, power equipment, lighting equipment, testing equipment, etc. Its power supply and distribution system is called'Auxiliary power supply and distribution system'Its power supply is directly provided by the municipal power supply.

High quality cables, cable trays, and sockets should be selected for electrical construction in the computer room. The sockets should be divided into mains powerUPSAnd waterproof sockets specifically designed for major equipment, with easily distinguishable markings. The lighting should choose high-end non glare lamps specifically designed for the computer room.

The power supply and distribution system in the computer room is the driving force for the safe operation of the computer room. The computer room often uses dedicated distribution cabinets to standardize the power supply and distribution system in the computer room, ensuring its safety and rationality.

The computer room generally adoptsuseDual circuit power supply of mains and generator, with the generator serving as the main backup power source, resulting in lower operating costs.

Lightning protection and grounding engineering for computer room

The grounding system of the computer room is a comprehensive information processing project involving multiple aspects, and is an important part of the construction of the computer room. Whether the grounding system is good is one of the key issues to measure the quality of a computer room construction. The computer room generally has four grounding methods: AC working ground, safety protection ground, DC working ground, and lightning protection ground.

When grounding in the computer room, two points should be noted:

1The signal system, power system, high voltage system, and low voltage system should not use a common ground circuit.

2The grounding of sensitive circuits should be isolated or shielded separately to prevent interference caused by ground return and electrostatic induction. The grounding of the computer room should adopt a comprehensive grounding scheme, and the comprehensive grounding resistance should be less than1Ohm.

The lightning in the computer room is divided into direct lightning and induced lightning. The protection against direct lightning strikes is mainly achieved by the lightning rods installed in buildings; The lightning protection work of the computer room (including the lightning protection of the computer room power system and weak current information system) is mainly to prevent lightning surges caused by induced lightning and overvoltage caused by other reasons.

Computer room air conditioning and ventilation engineering

The task of the computer room air conditioning system is to ensure that the equipment in the computer room can operate continuously, stably, and reliably. It is necessary to discharge the heat emitted by the equipment and other heat sources in the computer room, maintain a constant temperature and humidity in the computer room, and control the dust content of the air in the computer room. Therefore, it is required that the computer room air conditioning system has the ability to supply air, return air, heat, humidify, cool, dehumidify, and purify air.

The computer room air conditioning system is the most important equipment to ensure a good computer room environment, and it is recommended to use a constant temperature and humidity precision air conditioning system.

The new exhaust system in the computer room has two main functions: one is to provide sufficient fresh air to the computer room and create a good working environment for the staff; Secondly, maintain a positive pressure difference outside the computer room to prevent dust from entering and ensure better cleanliness of the room.

The airflow organization form in the computer room should be comprehensively considered in combination with the requirements of the computer system and building conditions. The position of the air ducts and vents of the new exhaust system should be arranged reasonably in conjunction with the air conditioning system and indoor structure. The air volume depends on the size of the air conditioning supply.

Fire protection engineering in the computer room

The computer room should be equipped with a gas extinguishing system, and the gas cylinder room should be located outside the computer room, with a pipe network structure. Nozzles should be installed on the ceiling, and the fire alarm system consists of a fire control box, smoke detectors, and temperature sensors networked together.

The fire protection system in the computer room should adopt a gas fire protection system, with commonly used gases being heptafluoropropane andSDETwo types of gases.
