Energy saving research on strengthening indoor air movement to improve thermal comfort

Based on a thermal comfort experiment, studies the influence of increasing air velocity on human thermal comfort and the proper air velocity. The results show that SET*(standard effective temperature) could remain unchanged by increasing air velocity, thereby the design values of temperature and relative humidity could be properly increased to save energy. Taking Tianjin as an example, analyzing results show shorter operation period for air conditioning systems and higher utilization ratio for direct evaporative cooling mode.
