Room decoration solution:
Construction engineering technology computer lab, computer room ground engineering is a very important part. Room floor generally use anti-static floor. Raised floor with removable characteristics, therefore, all equipment wire cable connection, pipe connection and maintenance are easily replaced. Activities under the floor space can be used as static pressure sent via air base, air distribution outlet for movable floor will be sent out of the room air-conditioning cold air into the room and heating equipment cabinet, because air air inlet floor and general activities floor interchangeability, so you can freely adjust the distribution of air flow inside the engine room.
Anti-static activities under the floor of the General need for moisture-proof surface treatment (such as wash-proof paint, etc.). If the space under the floor as the room air supply duct library, activities under the floor ground also need floor insulation treatment, ensure that the process of cold air to surface from the ground and cold air temperature and dew.
Room ceiling works
Room ceiling decoration use ceiling. The engine room the ceiling in the main role is to: to the roof above the ceiling of the space as a computer lab or static air back into the air libraries, you can layout the ventilation pipe; install fixed lighting, alignment, and various types of diffusers, automatic fire detectors; prevent dust falling, and so on. Engine room should choose metal aluminum ceiling, aluminum plate and its Widget should have a light, fire, humidity, sound-absorbing, non-dust, dust, etc.
Room wall project
Room interior decoration purpose is to protect the wall materials, indoor use conditions and create a comfortable, beautiful and clean environment. Interior decorative effect is determined by the texture, line and color three factors. At present, the room walls decorated in the most common is the wall materials (such as aluminum-plastic plate, color steel plate) finishes, it features: the surface is smooth, hermetically, easy to clean, no dust, no distortion. Wall facing grassroots moistureproof, shield, the heat insulation.
Room dividers engineering
In order to ensure that the engine does not appear in the column, the engine room building often used span structures. Debate on computer systems with different equipment on the environment, and the different requirements for air conditioning control, dust control, noise control and room management, often uses the partition wall is a big room space separated into smaller functions. Partition wall to light and thin, sound insulation, heat insulation.
Outside the room doors and the use of fire-burglar-proof doors and Windows, the engine room door and window generally use the frameless large glass door, so that both guarantees the safety of the machine room, and ensure the engine is transparent, bright effect.
Lab power supply
Room load power supply load according to level. Computer room load into master load and auxiliary equipment load. The primary load refers to computer and network systems, computer peripheral equipment and engine room supervisory system, this part of the supply and distribution system called "equipment supply and distribution systems, its power supply is very high quality requirements should be used in UPS uninterruptible power supply to ensure stability and reliability of electricity supply. Auxiliary equipment load means the air conditioning equipment, electric equipment, lighting equipment, testing equipment, its supply and distributionSystem known as "secondary power supply and distribution systems, its power supply power directly from the mains.
The engine of the electrical construction should choose high-quality cables, cable and socket. Outlet should be divided into commercial power supply, UPS and major equipment dedicated GFI, and indicate the difference easily. Lighting should select room dedicated no-glare advanced lighting. Room for electrical power distribution system is the engine room safe run power that the computer lab are often machine room exclusively used distribution Cabinet to regulate room supply and distribution system, assurance of supply and distribution system in the engine room safely and rationally. Room generally use the dual-Circuit City electricity, generators, generator as the primary reserve power supply, low running costs.
Computer room air conditioning and a new exhaust system
Room air-conditioning system's mission is to guarantee the room equipment is capable of continuous, stable, reliable running, you need to emit the engine equipment and other sources of heat, the heat to maintain the engine temperature and humidity, and control room dust content of the air. To do this requires the engine room air conditioning system with air supply and return air, heating, humidification, cooling, humidity and air purification. Room air-conditioning system's mission is to guarantee the room equipment is capable of continuous, stable, reliable running, you need to emit the engine equipment and other sources of heat, the heat to maintain the engine temperature and humidity, and control room dust content of the air. To do this requires the engine room air conditioning system with air supply and return air, heating, humidification, cooling, humidity and air purification. Room air-conditioning system is to guarantee the good engine room environment of the most important equipment, the use of constant temperature and humidity precision air conditioning system.
Room new exhaust system has two purposes: first, to the room provides sufficient fresh air, for the staff to create a good working environment; and the second one the maintenance room external positive pressure difference and avoid dust to enter, guarantee room cleanliness is better.
Room airflow organization forms should be considered in conjunction with the computer system requirements and architectural conditions into consideration. New exhaust system for wind pipes and air outlet location should be combined with air conditioning systems and indoor structure to reasonable layout. The air flow according to the air conditioning air.
Room lightning engineering
Room grounding system involves a wide range of comprehensive information processing is house-building project, an important content. Grounding system is a good measure of a computer room construction quality of one of the key issues. Room generally has four grounding: sharing and security protection, DC work and protection against lightning.
In the room when it should be noted that two-point grounding:
1, signal systems and power systems, high-voltage and low voltage systems should not use the total ground loop.
2. sensitive circuits of earthing should each isolation or shielding to prevent backflow and static induction and interference. Engine room should adopt an integrated ground grounding, comprehensive grounding resistance should be less than 1 ohm.
Rooms are divided into lightning and Thunder and lightning. Protection against lightning, mainly by the buildings of the lightning rod complete installed; the engine room of lightning protection (including the engine room the power system and ELV system lightning protection) work is mainly caused by lightning proof lightning surge and other causes of overvoltage.
The engine room monitoring system project
