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.
First, 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 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.
