摘　　要：本文采用主观问卷调查的方法研究了胸部送风工位空调下的吹风感。实验选取不同局部送风温度、风速和风口面积的9个局部送风工况,背景温度为28℃。采用吹风不满意率和吹风感投票值两种方法来评价吹风感。研究结果表明,胸部可能产生吹风感的几率最大,其次为上臂。为避免吹风感过大,应设置局部送风温度不低于25℃;而当局部送风温度低于25℃时,尽量设置局部送风风速低于0.6 m/s。吹风不满意率(吹风感投票值)随局部送风风速的升高而增大(降低),随局部送风温度的升高而降低(升高)。吹风感投票值与吹风不满意率在各工况下的变化规律是一致的。得出了吹风不满意率与吹风感投票值之间的关系式。The paper researched on the draft in the task ambient air conditioning with chest esposure by subjective questionnaires. The ambient temperature kept 28 ℃, the 9 conditiones with different levels of local supply air temperature, velocity and vent area were involved. Two index, draft rate and draft vote, were applied to evaluate draft. The results showed that the chest is the main target part of draft, second is the forearm. The local supply air temperature should be set to be lower than 25℃, and the local supply air velocity should be lower than 0.6 m/s if the air temperature is no more than 25 %, in order to decrease the risk of draft. Draft rate increased with the local supply air velocity, decreased with the local supply air temperature. Draft vote changes with the local supply parameters the same with the draft rate. The correlations between draft rate and draft vote was built.
