Why does the computer room need to install a temperature and humidity monitoring system? Shenzhen Jitong, an environmental monitoring expert in computer room, will answer your questions. A large number of semiconductor devices, resistors and capacitors are used in computer equipment. When the computer is turned on, the ambient temperature will affect its normal work. When the temperature is too high, some components may not work normally, or even lose their functions completely, resulting in the failure of computer equipment.

In order to ensure the safe and reliable operation of the computer, in addition to strictly controlling the temperature, we should also control the humidity within the specified range. Generally speaking, when the relative humidity is lower than 40%, the air is considered dry; When the relative humidity is higher than 80%, the air is considered humid; When the relative humidity is 100%, air is saturated. When the relative humidity remains constant, the higher the temperature, the greater the pressure of water vapor, and the greater the influence of water vapor on computer equipment. With the increase of pressure, the water film formed by water vapor on the surface of components or dielectric materials becomes thicker and thicker, resulting in "conductive path" and arc phenomenon, resulting in equipment failure. The harm of high humidity to computer equipment is obvious, and the harm of low humidity is sometimes more serious. Under the same conditions, the lower the relative humidity, the drier it is, and the higher the electrostatic voltage, the more obvious the influence on the normal work of electronic computer equipment. The experiment shows that when the relative humidity of the computer room is 30%, the electrostatic voltage is 5000v, when the relative humidity is 20%, the electrostatic voltage reaches 10000V, and when the relative humidity is reduced to 5%, the electrostatic voltage can reach 20000V V. ..

Therefore, it is necessary to install a temperature and humidity monitoring system in all important parts of the computer room, record the temperature and humidity curve for managers to inquire, and start the alarm as soon as the temperature and humidity exceed the limit; Remind managers to adjust the working setting value of air conditioner or adjust the distribution of equipment in the computer room in time, and the system can also automatically adjust the working setting value of air conditioner. At the same time, the curves recorded by the system can be used for reference by computer room managers; In order to facilitate timely adjustment according to the local temperature and humidity conditions in each season and prevent unnecessary equipment damage caused by temperature and humidity quality in time; After the problem occurs, it is easy to find and solve the problem according to the historical curve.
