From August 1st to 4th, the "2025 Laboratory Management Training Seminar of the Laboratory Management Work Branch of the Chinese Society of Higher Education and the 8th Executive Director Work Meeting of the 2025 Branch Council" was successfully held in Hohhot. Yishi Energy saving Technology (Shanghai) Co., Ltd. (hereinafter referred to as "Yishi Technology") was invited to attend the conference and explore laboratory energy-saving ideas and practical experience with the attending experts.

At the meeting, Ruan Hongzheng, Chairman of Yishi Technology, gave a speech titled "Practical Sharing of Comprehensive Energy saving Solutions for Air Conditioning and Ventilation Systems in University Laboratories", analyzing the "three highs" pain points in laboratory construction:

• High safety risks (physical and chemical laboratory risks are 5-10 times higher than ordinary laboratories);

• High construction costs (investment 3-5 times higher than ordinary buildings);

• High usage cost (ventilation and air conditioning systems account for 50% -70% of the total building energy consumption);

He also pointed out the common problems in chemical laboratories, such as strong chemical odors, energy waste caused by full supply and exhaust of fresh air, insufficient air conditioning configuration affecting comfort, high negative pressure, and loud noise.

Regarding these issues, Ruan Hongzheng introduced Yishi Technology's "Laboratory Ventilation and Air Conditioning System Safety and Energy saving Overall Solution". This plan can optimize the area of the air shaft and the spatial configuration of the roof equipment layer to improve utilization, reduce building electricity load, and save HVAC system equipment investment by more than 47%; While ensuring the safety and stability of the laboratory environment, reduce operating energy consumption by over 67%.

Ruan Hongzheng took two university laboratories as examples to describe the practical application effect of the scheme: after 877 Bernoulli internal air make-up exhaust cabinets were used in the State Key Laboratory of a chemical engineering college in Zhejiang, the total exhaust air volume dropped to 600000 m ³/h, and the fresh air volume dropped to 240000 m ³/h, significantly reducing the investment in air conditioning, power supply, operating costs and environmental pressure; A newly built key laboratory at a university in East China has adopted 470 sets of this exhaust cabinet, reducing the total exhaust volume by 40% and the total fresh air volume by 60%. The safety performance and energy-saving effect meet the standards, providing a model for subsequent construction.

The on-site audience expressed that the energy-saving ventilation solution of Yishi Technology represents the future trend of laboratory development, which will promote the transformation of laboratory construction from single function satisfaction to deep integration of safety and energy conservation, accelerate the evolution of the industry towards intelligent control and modular integration, and be in line with the sustainable development strategy of university scientific research, helping the industry to transform and upgrade towards low energy consumption and high safety.

The Yishi Technology Exhibition Area has attracted laboratory management leaders and industry experts from various universities to stop and have in-depth exchanges on the pain points of laboratory ventilation system renovation and the feasibility of energy-saving solutions. Many participants consulted the adaptability of their own university laboratory operations and consulting solutions in different scenarios. The team from Yishi Technology responded carefully and the atmosphere of on-site discussions was lively, providing practical and feasible paths for universities to reduce energy consumption costs and improve safety management efficiency in scientific research. It also injected practical momentum into the industry's exploration of green transformation models.
