Dear Experts, I have created model of house (Type 56). Heating is set as ideal with some limitation in power. Then I compare indoor surface temperature between case with 1.5 ACH infiltration and without (0 ACH). It is appear that indoor surface temperature are higher in the winter and lower in the summer if infiltration is 1.5ACH.How it is possible? Convective heat transfer coefficient are set constant (11 kJ/hm2K for indoor surfaces). Regards, -------------------------------------------------------------------- Karol BANDURSKI M. Sc.
