Temperature and humidity control in the server room is a key factor to ensure stable operation of the equipment and extend its service life. Here are some technical requirements and standards:
Temperature control:
According to the "Electronic Information System Computer Room Design Specification GB50174–2017"
, the temperature of Class A and Class B computer rooms should be controlled within the range of 18–22°C. This temperature range helps maintain device stability and performance while avoiding hardware damage caused by overheating.
Humidity control:
Relative humidity should be controlled between 40%-60%. Too low humidity can cause static electricity problems and increase the risk of equipment failure; too high humidity can lead to equipment corrosion and mold growth.
Air dust concentration:
When tested under static conditions, the number of sharp particles greater than or equal to 0.5um per liter of air should be less than 18,000. This helps reduce equipment failures and maintenance costs.
Air conditioning system design:
The data center requires year-round cooling, and cooling load calculations should be performed for each room that requires cooling. The summer cooling load of the air conditioning system should be determined based on factors such as heat dissipation of electronic information equipment, heat incoming from the building envelope, and solar radiation heat
.
Airflow organization:
The air conditioning system form and air flow organization of the main computer room should meet the heat dissipation requirements of all equipment in the room. The airflow direction of electronic information equipment in the rack and adjacent racks should be consistent, and the racks should be arranged in a manner such that hot and cold aisles are separated.
System monitoring and control:
The monitoring system of data center refrigeration and air-conditioning facilities should meet the environmental requirements for the stable operation of electronic information equipment, and should take into account energy conservation and operation and maintenance requirements. The monitoring system should be connected to the operating parameters of the refrigeration and air-conditioning facilities. When the parameters are abnormal, the monitoring system will alarm.
Fire protection and evacuation :
The fire resistance level of the electronic information system room should not be lower than Level 2. A partition wall with a fire resistance rating of not less than 2h should be installed between the main computer room and other parts.
Interior decoration:
The ceiling, wall panels and partitions of the main computer room should be non-combustible and organic composite materials should not be used .
Fresh air system:
The fresh air system in the main room should bear the entire dehumidification load of the air conditioning area, and its processing method should be determined based on the calculated outdoor temperature and air supply status point requirements.
Humidity independent control:
The humidity in the data center should be controlled by special equipment, and a strategy of independent temperature and humidity control should be adopted.
These technical requirements and standards help ensure that the temperature and humidity of the server room are controlled within an appropriate range, thereby ensuring the stable operation of the equipment and the security of data.
