Precision air conditioners are generally deployed in independent spaces and only control the ambient temperature. When the cabinets are fully equipped, there are disadvantages of poor cooling effect and high energy consumption, especially for servers. When the equipment is deployed in a centralized manner, the requirements for the ambient temperature are high. The traditional indoor open cooling cannot immediately take away the heat of the local server, resulting in the performance degradation or even downtime of the server.

Limited by the circulation space, when the air duct is blocked, the cooling effect will drop significantly, which will have a great impact on the performance of high-end equipment. In addition, due to the consideration of space utilization in the modular machine room, the possibility of redundant cooling is generally small. When cooling When equipment failure occurs, high energy consumption equipment can only be stopped, which brings challenges to the operation and maintenance of information equipment.
