This paper focuses on the research of how to realize sustainable operation and maintenance management by optimizing the hardware and implementing intelligent control of the cooling source system

while ensuring air quality and reducing energy consumption. In the scenario of intelligent buildings

by integrating hardware devices

sensing devices and control systems

it can not only meet the air quality standards of the project's environmental space

but also achieve the goals of energy conservation

consumption reduction and efficient management and control. For the control system

this paper conducts specific practical analysis combined with the actual cooperative application cases of different control units such as PLC and MCU.
