Brief introduction of fresh air system in computer room;
Air conditioning and fresh air system are the guarantee of operating environment. The highly reliable operating environment of the equipment in the computer room, including temperature, humidity and cleanliness. The computer field system runs at constant temperature and humidity all year round. Only window sealing can ensure the normal operation of temperature and humidity of the system. The computer equipment in the computer room generates a lot of heat and has strict requirements on the amount of dust in the environment, which all put forward higher requirements for the air conditioning system. In order to keep the temperature and humidity of the computer room constant, it is necessary to choose a special precision air conditioning for the computer room. At the same time, the computer room must be supplemented with fresh air. The fresh air in nature can only enter the computer room after being treated by the fresh air system, forming an internal circulation and filtering the fresh air to meet certain purification requirements.
Functions of fresh air system in computer room:
1. The fresh air system of the machine room can maintain the positive pressure difference outside the machine room, avoid dust from entering and ensure the better cleanliness of the machine room. The air distribution form of computer room should be considered in combination with the requirements of computer system and building conditions. The air volume depends on the air supply volume of the air conditioner and the number of operators in the computer room. Half of the value is the fresh air volume per person: 50m3/h fresh air ventilation system can be installed by hanging or cabinet units, and fresh air and polluted air can be circulated independently and bidirectionally through air ducts. The fire damper should be installed in the fresh air ventilation system and can be connected with the fire fighting system. In case of fire accident, the fresh air inlet can be automatically cut off. If the machine room is unattended, there is no need to set up a fresh air ventilation system.
2. The fresh air system of the computer room can provide enough fresh air for the computer room and keep the positive pressure difference of the computer room. 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. The function of the precision air conditioning system in the computer room is to ensure the continuous, stable and reliable operation of the equipment in the computer room, discharge the heat emitted by the equipment and other heat sources 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 precision air conditioning system in the computer room is required to have the capability of air supply, air return, heating, humidification, cooling, dehumidification and air purification. Precision air conditioning system in computer room is the most important equipment to ensure a good computer room environment, and precision air conditioning system with constant temperature and humidity should be adopted.
Regarding the role of fresh air system in the computer room, the small series of home improvement network is here to introduce it to you.
