The course of Heating Ventilating and Air-conditioning (HVAC), which is a main course in the building environment and facilities engineering specialty, is deemed to be very suitable for the implementation of research-oriented teaching mode. Considering the contents and characteristics of the specialty course, the authors analyze and summarize some main points that should be paid special attention to during the practice of the task-driven research-oriented teaching mode and also discuss on the feedback and continual improvement of this teaching mode. The authors hope it to be helpful in the cultivation of high quality and innovation-oriented talents through the teaching mode reform.
