Teaching--- I taught “Theory of Combustion” for about 300 undergraduate students from 2003 to 2008. The textbook for this course was revised and the experimental apparatus was redesigned. From 2011, I taught “Engineering Heat Transfer” for undergraduate students. I participated in the teaching reform project of the course “Theory and Method of Engineering Testing” for graduate students, which won the second prize of the Seventh Session of Higher Education Tianjin Municipal Teaching Achievement Award in 2013. I also undertook the graduate courses “Thermodynamic Cycle Analysis and Advanced Development” and “Modern Refrigeration and Heat Pump Technology”. By now, I have supervised 15 undergraduate students, among which six students’ theses were rated as excellent, and I was awarded excellent graduation thesis supervisor twice as well. I also supervised 7 groups of undergraduate students to complete their innovation training projects, among which two projects were awarded the second prize in The Seventh National College Students’ Social Practice and Science and Technology Competition of Energy Saving and Emission Reduction in 2014 and the first prize in The Third Embraco Innovation Contest in2015, respectively. I have supervised 13 master students and assisted in supervising 6 PhD students. Among them, a master student, Miss Yang Yingying, won the scholarship of Weichai Engine Co. Ltd. and the national scholarship for studying abroad in 2014, and a PhD student, Mr Dai Baomin, was awarded the doctoral graduate national scholarship in 2015.
Research--- I am engaged in the application study of new environment-friendly working fluids in refrigeration and heat pump systems, especially the development of CO2 transcritical systems. I developed the prototype of rolling piston expander and swing expander to replace throttling valves in traditional CO2 transcritical cycles for the first time in
Social Service --- I was the reviewer of a dozoen or more international journals and domestic journals such as Energy, Applied Thermal Engineering, Journal of Heat transfer, and CIESC Journal. I participated in the writing of 8.1 chapter in the book entitled “
International cooperation --- I cooperated with Panasonic Co., Ltd. of
