The impact affects electronic components, mechanical parts, and materials. If environmental conditions do not meet the requirements for these devices, it will reduce the reliability of the computer, accelerate the aging of components and materials, shorten the lifespan of the machine, and even lead to the loss of important data and malfunctions.

Harsh environments not only affect the physical and mental health of computer operators but also impact work efficiency, cause operational errors, and in severe cases, endanger the safety of personnel and equipment. Therefore, understanding the role and impact of computer room environmental conditions is crucial. GB2887-2000 classifies computer room environmental conditions into two levels, A and B.

The impact of environmental conditions on computer rooms includes: the effects of temperature, humidity, dust, harmful gases, and electromagnetic interference.
