The　traditional　Chinese　Kang　system　is　a　kind　of　ancient　domestic　heating　system　in　China,　which　is　widely　used　in　the　northern　rural　area　of　China　since　it　has　the　advantage　of　heating　the　room　by　utilizing　waste　heat　of　cooking.　However,　the　traditional　Chinese　Kang　is　facing　the　challenge　of　dropping　out　of　use　due　to　it　heating　the　room　by　burning　biomaterials　or　coal　directly.　In　order　to　reform　the　existing　Kang　system,　a　novel　Kang　system　which　employs　a　capillary radiation　mat　as　heating　terminals　was　proposed　in　this　research.　Moreover,　a　dual　heat　source　of　solar　energy　and　air　source　heat　pump　was　used　in　the　system　to　replace　biomaterials　and　coal.　In　order　to　validate　the　feasibility　of　the　system,　a　numerical　simulation　was　performed　in　this　research　to　obtain　the　temperature　and　flow　distributed　characteristics　in　the　heating　room　and　the　results　showed　that　this　system　could　provide　a　comfortable　indoor　environment　for　residents.　©　Springer　Nature　Singapore　Pte　Ltd　2020.
