Comparison of Parallel and Serial Methods for Determining Clothing Insulation
Abstract
This paper examines the fundamental differences between the parallel and serial methods for the calculation of clothing insulation using a thermal manikin and demonstrates the differences in the insulation values calculated using these two methods. The parallel method is based on the condition that manikin surface temperatures remain uniform UST, while the serial method is based on the condition that manikin heat fluxes remain uniform UHF. Eleven clothing ensembles were evaluated on manikins in UST mode. Three of them were also evaluated on manikins in UHF mode. Insulation values were then calculated using both the serial and parallel methods. Result from UST mode showed that the parallel insulation values ranged from 1.24 to 5.79 clo, while the serial insulation values ranged from 1.43 to 7.98 clo.
