The excellent desk personalized ventilation scheme is found in this paper by the way of comparing the four
winter air supply schemes, basing on the numerical simulation software of CFD. We find that air supply quality and air
supply angle are both the important factors to personalized ventilation individual comfort in winter. The air temperature
and velocity surrounding the human body of the excellent desk personalized ventilation scheme are discussed. It comes to
the conclusions that under simulated conditions the excellent desk personalized ventilation scheme can better satisfy the
human body comfort on the surrounding air temperature and healthy than the traditional air conditioning, and it is easier
to achieve energy saving too.
