Generally speaking, the temperature of the machine should be controlled between 20℃～24℃ and the relative humidity should be kept within the range of 45%～65%.

The country has a national standard GB2887-89 "Technical Conditions for Computer Station Sites" concerning the computer room site, in which Article 4.4.1.3 stipulates: the ambient temperature and humidity standards in the computer room when the computer is turned on. The ambient temperature is: Class A 22±2°C, Class B 15～30℃, C grade 10～35℃; ambient humidity: A grade 45%～65%, B grade 40%～70%, C grade 30%～80%; the standard of general communication room should reach A grade standard.

Extended information:

The equipment in the computer room is composed of a large number of microelectronics, precision mechanical equipment, etc., and these equipment use a large number of electronic components, mechanical components and materials that are easily affected by temperature and humidity.

Temperature has a greater impact on the electronic components, insulating materials and recording media of computer room equipment; for semiconductor components, for every 10°C increase in room temperature within the specified range, the reliability will be reduced by about 25%;

For capacitors, when the temperature increases by 10°C, the service time will decrease by 50%; the insulating material is also sensitive to temperature. If the temperature is too high, the structural strength of the printed circuit board will be weakened. If the temperature is too low, the insulating material will become brittle. It will weaken the structural strength; for the recording medium, too high or too low temperature will cause data loss or access failure.

The impact of humidity on computer equipment is also obvious. When the relative humidity is high, water vapor forms a water film on the surface of electronic components or dielectric materials, which easily causes passages between electronic components; when the relative humidity is too low, it is easy to A higher electrostatic voltage is generated. The test shows that: in a computer room, if the relative humidity is 30%, the electrostatic voltage can reach 5000V, the relative humidity is 20%, the electrostatic voltage can reach 10000V, and the relative humidity is 5%. Up to 20000V, and the electrostatic voltage up to tens of thousands of volts has an obvious impact on computer equipment.

The precision air conditioner for the computer room is a special air conditioner designed for the computer room of modern electronic equipment. Its working accuracy and reliability are much higher than that of the ordinary air conditioner. To improve the stability and reliability of the equipment in the computer room, the temperature and humidity of the environment must be strictly controlled within a specific range. The precision air conditioner in the computer room can control the temperature and relative humidity of the computer room at plus or minus 1 degrees Celsius, which greatly improves the life and reliability of the equipment.
