Two practical crawlspace heating systems introduced in detached houses have been chosen as a field study.One is the crawlspace warm air heating system and the other is the crawispace hot water circulation system.Based on the field study result,by using the simulation software,THERB,the effectiveness of the crawlspace warm air heating system has been examined.The effect of the factors,such as the wind amount circulating between crawispace and indoor space,foundation insulation condition,and heat amount into the crawlspacc,on the indoor thermal environment has been analyzed.Based on these analyses,the measured crawlspace heating system can make the average temperature of the living room above 20 ℃.These two houses have excellent thermal environment.According to the simulating result,heat amount input into crawlspace,which can make comfortable indoor thermal environment,for every month in heating period has been roughly concluded,and they arc 600 W in December and March and 800 W in February and January,respectively.
