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

The computer room air conditioner is a high-precision air conditioner specially designed for the computer room.

The computer room air conditioner can not only control the temperature of the computer room, but also control the humidity at the same time, so it is also called the special air conditioner for the computer room of the constant temperature and humidity air conditioner.

The main service object of the computer room air conditioner is the computer, which provides stable and reliable IDC for the computer room and detects the working temperature, relative humidity and air cleanliness of the computer room. It has the characteristics of high sensible heat ratio, high energy efficiency ratio, high reliability and high precision.

Specific features of computer room air conditioners:

1. Refrigeration all year round

Due to the large amount of heat generated in the computer room, excessive heat generation can lead to a series of problems. Some IDC rooms have a calorific value of more than 300w/㎡, so they are cooled throughout the year.

2. High sensible heat ratio

The sensible heat of the computer room air conditioner is relatively high, generally above 0.9.

Large air volume and small enthalpy difference are the essential differences between computer room air conditioners and other air conditioners.

Using a large air volume can keep the outlet air temperature from being too low, and increase the number of air changes in the computer room, which is beneficial to both server and computer operations. If the temperature of the computer room changes too much in a short period of time, it will cause server operation errors, and if the humidity in the computer room is too low, it will cause static electricity.

3. High energy efficiency ratio

The computer room air conditioner adopts a scroll compressor, and the maximum COP can reach 5.6. The energy efficiency ratio of the whole machine is above 3.0.

4. High-precision design

The computer room air conditioner can adjust not only the temperature, but also the humidity, and the accuracy is very high.

Computer room air conditioners generally require a temperature accuracy of ±2°C and a humidity accuracy of ±5%. High-precision computer room air conditioners can have a temperature accuracy of ±0.5°C and a humidity accuracy of ±2%.
