Decoration Engineering
Including: ceiling, raised floor, wall, partition, door, insulation layer, etc.
▲ ceiling: the ceiling should be used for the decoration of the ceiling of the machine room. The secondary function of the ceiling in the machine room is that the space above the ceiling to the ceiling is used as the static pressure return air reservoir of the machine room, and the ventilation duct can be arranged; Fixed lighting fixtures, wiring, various air outlets and automatic fire extinguishing detectors; Avoid falling dust, etc. Metal aluminum ceiling shall be selected for the machine room, which has the functions of light weight, fire prevention, moisture-proof, sound absorption, no dust and no dust collection.
▲ raised floor: anti static raised floor shall be laid in the air of the machine room. The raised floor has the characteristics of assembly. Therefore, the connection of wires and cables, pipes and inspection, modification and replacement of all equipment are very convenient. The space under the raised floor can be used as a static pressure air supply warehouse. The cold air sent by the air conditioner in the machine room is sent into the room and the cabinet of heating equipment through the air outlet raised floor. Due to the interchangeability between the air outlet floor and the ordinary raised floor, the air distribution in the machine room can be adjusted freely. The ground surface under the raised floor generally needs to stop heat preservation and moisture-proof treatment.
▲ wall: the purpose of the interior wall decoration of the machine room is to maintain the wall structure, ensure the indoor application conditions, and create a comfortable, beautiful and clean environment. The decorative effect of the interior wall is composed of three elements: texture, line and color. At present, the most rare wall decoration in the computer room is that the wall materials include aluminum-plastic plate and color steel plate, which are characterized by flat appearance, good air tightness, easy cleaning, no dust and no deformation. The wall facing base course shall be treated with moisture-proof, shielding and thermal insulation.
▲ partition: the machine room is set with different functional zones according to the computer operation characteristics and detailed requirements of equipment, and the partition wall is used to separate the large machine room space into smaller functional areas. The partition wall shall be light and thin, sound insulation and heat insulation. It is required to have transparent effect. Generally, tempered glass is used for partition.
▲ doors: there should be no less than two safe exits in the machine room, and they should be set at both ends of the machine room. The doors should be opened in the evacuation direction and can be closed automatically. Therefore, fire and anti-theft doors are mostly used for the external doors of the machine room, and glass doors are generally used for the internal doors of the machine room, so as to ensure the safety of the machine room and the transparent and bright effect in the machine room.
electrical engineering
Including: distribution cabinet, UPS, lighting, diesel generator, lightning protection and grounding, etc.
▲ power distribution cabinet: the power supply and distribution system of the machine room is the power guarantee for the safe operation of the machine room. The power distribution system shall adopt the system with frequency of 50Hz and voltage of 220 / 380V. The machine room often adopts the public distribution cabinet to standardize the power supply and distribution system of the machine room, so as to ensure the safety and rationality of the power supply and distribution system of the machine room. The load of computer room is divided into main equipment load and auxiliary equipment load. The main equipment refers to the computer and network system, the internal equipment of the computer and the monitoring system of the computer room. Its power supply quality requirements are very high. UPS discontinuous power supply should be used to ensure the fluctuation and reliability of power supply. Auxiliary equipment refers to air conditioning equipment, power equipment, lighting equipment, maintenance and test equipment, etc., and its power supply is indirectly supplied by municipal power. High quality cables, trunking and sockets shall be selected for electrical construction in the machine room. The cable should be copper core shielded conductor, laid in metal trunking and far away from the computer signal line as far as possible. The socket shall be divided into waterproof sockets shared by mains power, ups and secondary equipment, and shall be clearly marked. Public non glare primary lamps shall be selected for lighting.
▲ UPS: UPS discontinuous power supply is adopted to ensure the fluctuation and reliability of power supply. When the utility power is suddenly supplied by infill power supply, UPS can quickly switch operation online, the host computer will not lose data, and can ensure the continuous operation of computer equipment in the computer room within a certain period of time.
▲ lighting: the lighting power supply of computer room belongs to the scope of auxiliary power supply, but it has certain particularity and independence. The lighting of the computer room will not only affect the task efficiency and physical and mental health of computer operators and software and hardware maintenance personnel, but also affect the reliable operation of the computer. Therefore, the lighting mode should be reasonably selected, and the lamp type, layout and some related equipment can not be ignored in the decoration electrical engineering.
▲ diesel generator: the machine room shall be equipped with uninterruptible power supply system. Generally, the utility power and diesel generator double circuit power supply plus UPS power supply system are adopted. The diesel generator is used as the secondary backup power supply with low operation cost.
▲ lightning protection: lightning is divided into direct lightning and inductive lightning. The protection against direct lightning is mainly completed by the lightning rod installed in the building. The lightning protection of the machine room mainly refers to the lightning surge caused by induction lightning and overvoltage caused by other reasons, including the lightning protection of power supply and signal.
▲ grounding: AC task grounding, safety maintenance grounding, DC task grounding and lightning protection grounding should share a group of grounding installation, and the grounding resistance shall be determined according to the minimum value; If the lightning protection grounding is set independently, the other three grounding should share a group of grounding installation, and its grounding resistance should not be greater than the minimum value, and measures to avoid ground potential return stroke shall be taken according to the requirements of the current national code design standard for building lightning protection.
Air conditioning environmental engineering
Including: fine air conditioner, fresh air fan, water leakage detection, etc.
▲ fine air conditioner: the duty of the air conditioner in the machine room is to ensure that the equipment in the machine room can operate continuously, fluctuate and reliably, discharge the heat distributed by the equipment and other heat sources in the machine room, maintain the constant temperature and humidity in the machine room, and control the dust content in the air in the machine room. Therefore, the air conditioner in the machine room is required to have the ability of air supply, air return, heating, humidification, cooling, dehumidification and air pollution. The air conditioning system in the machine room is the most important equipment to ensure a good machine room environment, and it is appropriate to adopt constant temperature and humidity fine air conditioning system.
▲ fresh air fan: the fresh air in the machine room plays two main roles. One is to provide enough fresh air for the machine room and create a good task environment for the task personnel; Second, maintain the positive pressure outside the machine room to prevent dust from entering and ensure better cleanliness of the machine room.
▲ water leakage detection: the water leakage of fine air conditioner and water pipe in the machine room occurs from time to time. In order to prevent the occurrence of dangerous situations, it is very necessary to lay water leakage detection system in the machine room. At present, the leakage detection system commonly used in the United States is used for leakage detection, and the sensing cable line is used to distinguish and monitor water, acid / alkali and oil liquids (this scheme is mainly aimed at water detection).
Fire engineering
The machine room shall be equipped with gas fire extinguishing system and automatic fire alarm system. The common fire extinguishing agents are heptafluoropropane, aerosol, CO2, etc.
Heptafluoropropane (FM200) cylinder room should be set outside the machine room, which is of pipe network structure, and the nozzle should be set downward on the ceiling layer of the ceiling. Nozzles shall also be set at the upper part of the ceiling layer and the lower part of the floor of the important machine room to truly play the role of omni-directional plane fire extinguishing.
