Review on Heat and Mass Coupled Transfer of Wooden Passive House Wall in the Cold Region

Abstract

In this paper four aspects were reviewed in macroscale and microscale heat and mass coupled transfer shown by the transfer process between external and internal walls of the wooden passive house. (1) heat and mass coupled transfer process of external wooden passive house wall in the cold region; (2) influences of high temperature difference on heat and mass transfer feature parameters of wooden passive house walls; (3) heat and mass transfer process of wooden wall surface in cold region; and (4) the feature of heat and mass transfer shown by coupling characteristics between internal and external of the wall. The importance of heat and mass transfer of wooden passive house wall in cold region on the research of maximumly increasing wall’s acclimatizing ability and the detail research on energy saving performance was analyzed. Finally, some suggestions were improved on current research status and developed direction.
