In order to establish the new college and to meet the demands of building micro-nano processing laboratories, XMU funded 20,100,000 CNY allocated by Ministry of Education of the People’s Republic of China to reconstruct Class 100/1000 clean rooms in Yixuan Building at the end of 2015. Fifteen sets of latest micro-nano and grapheme processing instruments were introduced.

After nearly 8 months preparations by the staff of Pen-Tung Sah Institute of Micro-Nano Science and Technology, new laboratories were established and following tests were begun from July 15th, 2016 and on September 15th the new laboratories were officially put into use. Constructed with international standards, these new laboratories can provide and maintain constant, steady environmental indexes including temperature, humidity and pollutant particles, so scientific instruments can be protected well and efficiency of instrument application will be enhanced in these clean rooms.

While clean rooms are built and maintained under high standards, energy consumption rapidly increases to a very high level. In order to reduce energy consumption and build eco-friendly laboratories, Engineer Wang, Jiaqin and Engineer Li, Ming from Pen-Tung Sah Institute of Micro-Nano Science and Technology did numerous researches and finally presented a reconstruction plan which only needs a 15,000 CNY investment on both software and hardware update at the end of 2016. Wang and Li also debugged and tested the system to ensure its stability and reliability. Wang and Li set 4 levels of air-circulation flow rate which can be intelligently switched through computer program: flow rate will be turned to lower levels during idle hour such as nights, weekends and holidays, while flow rate will be gradually turned to higher levels during busy hour and instruments reservation system can be linked to the program to ensure dynamic regulation of the flow rate. In 2 months trial operation, the system maintains steady and 33.7﹪ electric energy is saved on year-on-year basis. From acquired data, the system is estimated to save more power during summer and over 300,000 CNY power fund is saved through Wang & Li’s reconstruction plan.

This air-circulation regulation system is base on independent research and development of XMU and can be applied to management of clean rooms of other colleges or schools or even other organizations of the public.
