Thermal comfort zone study based on equivalent temperature under task air conditioning system

Evaluates the local and overall thermal sensation using equivalent temperature index in the non-uniform thermal environment of task air conditioning system. Conducts the human thermal test in a mockup office, and obtains the data of local sensation and equivalent temperatures under different stimulating conditions. The results show that there is an obvious separation phenomenon between the equivalent temperature of stimulating site and that of non stimulating sites. The air temperature and velocity are the important factors to affect the equivalent temperature of the stimulating site. From the scatter plot, finds a good linear relationship between human thermal sensation vote and equivalent temperature. Obtains the equivalent temperature comfort zone for the non-uniform thermal environment with task air conditioning through the fitting method.
