In　this　study,　a　concept　of　air-source　heat　pump　using　heat　pipes　as　heat　radiator　system　(ASHPP)　for　room　heating　was　proposed.　The　heat　pipes　radiator　was　developed　to　replace　the　heating　terminal　equipment　used　in　traditional　heat　pump　plants.　A　tested　room　with　artificial　load　was　constructed　and　an　experimental　apparatus　of　ASHPP　system　was　developed.　Heat　radiator　performances　with　different　kinds　of　refrigerant　and　different　refrigerant　mass　filling　ratio　of　heat　pipe　have　been　experimentally　investigated.　The　variations　of　system　heating　performance　under　the　condition　of　different　indoor　air　temperature　and　outdoor　air　temperature　were　researched.　The　purpose　of　this　study　is　to　provide　technique　reference　for　developing　new　heat　pump　room　heating　system.　(C)　2018　Elsevier　Ltd　and　IIR.　All　rights　reserved.
