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”).

When he first began to study evaporative cooling technology, Gu Guobiao was only 22 years old and had just joined the recently established Institute of Electrical Engineering. “Not to do with foreign duplication of things, to do one or two things beyond the foreign.” This idea, once regarded as “ridiculous”, became the lifelong belief of him and his team. For decades, they have been thinking about how to apply evaporative cooling technology to a broader field, not only to meet the country's major needs, but also to play a role in the main battlefield of the national economy.
