1, the country divides the computer rooms into Class A, Class B and Class C. The requirements for the three types of computer rooms are different, and the requirements for various construction standards and operation indicators are reduced in turn.

2. In terms of temperature and humidity, the requirements of Class A and Class B computer rooms are the same, with the temperature of 23 1℃ and the humidity of 40%~55%. The temperature of Class C machine room is 18~28℃ and the humidity is 35%~75%.

3. Therefore, we need a quick-acting ring monitoring system to control the temperature and humidity in a suitable range to ensure the normal operation of all equipment in the computer room.

This parameter comes from GB50 174-2008 Code for Design of Computer Rooms of Electronic Information Systems.
