In this paper, we will focus on the eight computing power hubs and 10 national data center clusters under the “East Counts, West Counts” project.

basket filter is mainly composed of receiver, cylinder, filter basket, flange, flange cover and fasteners. Installed in the pipeline can remove large solid impurities in the fluid, so that machinery and equipment (including compressors, pumps, etc.), instrumentation can work and operate normally, to stabilize the process, to protect the role of safe production.

The operating principle of the electronic expansion valve is based on an electromagnetic or stepper motor drive. The controller receives signals from temperature and pressure sensors, and after calculation, outputs a pulse width modulation (PWM) signal to the stepper motor or electromagnetic coil, which drives the valve needle up and down, thus changing the size of the valve opening, and realizing the precise control of the amount of refrigerant entering the evaporator.

Guests from outside the university mainly included: Prof. Fan Xin, Secretary of the Party Committee of New Ziguang Group, Mr. Zhang Jie, President of China Association of Survey and Design, Chief Engineer of Beijing Architectural Design and Research Institute, and Prof. Zhu Yingxin, Chairman of the Teaching Guidance Sub-committee of the Higher Education Schools Specialized in Building Environment and Energy Application Engineering (hereinafter referred to as the “China Association of Survey and Design, Building Environment and Energy Application Sub-committee”).
