Free door-to-door installation of air conditioners in computer rooms in Japan

  As the name suggests, the machine room air conditioner is a high-precision air conditioner used in the * * machine room
Because it can not only control the temperature of the machine room, but also control the humidity at the same time, it is also called the special air conditioner for the constant temperature and humidity air conditioner machine room
In addition, it is also called the machine room precision air conditioner because of its high precision in temperature and humidity control
The main service object of the air conditioner in the machine room is the computer, which provides stable and reliable IDC for the machine room and detects the working temperature, relative humidity and air cleanliness of the machine room
It has the characteristics of high sensible heat ratio, high energy efficiency ratio, high reliability and high precision
The equipment in the computer room is composed of a large number of microelectronics and precision mechanical equipment, which use a large number of electronic components, mechanical components and materials vulnerable to temperature and humidity Temperature has a great influence on electronic components, insulating materials and recording media of computer room equipment; For example, for semiconductor components, the reliability will be reduced by about 25% for every 10 ℃ increase in room temperature within the specified range; For the capacitor, the service time will decrease by 50% when the temperature increases by 10 ℃; Insulating materials are also sensitive to temperature
If the temperature is too high, the structural strength of printed circuit board will become weak
If the temperature is too low, the insulating materials will become brittle, which will also weaken the structural strength; For the recording medium, too high or too low temperature will lead to data loss or access failure The influence 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 is easy to cause a path between electronic components; When the relative humidity is too low; It is easy to produce high electrostatic voltage
The test shows that in the 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%, the electrostatic voltage can reach 20000V, and the influence of electrostatic voltage up to tens of thousands of volts on computer equipment is obvious
Precision air conditioner in computer room is a special air conditioner designed for modern electronic equipment room
Its working precision and reliability are much higher than ordinary air conditioner
In order to improve the stability and reliability of these machine room equipment, it is necessary to strictly control the temperature and humidity of the environment within a specific range
The precision air conditioner in the machine room can control the temperature and relative humidity of the machine room at plus or minus 1 ℃, which greatly improves the service life and reliability of the equipment
