Research on Desk Personalized Ventilation in Winter Based on CFD

ABSTRACT

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.
