As　a　clean　and　sustainable　electrified　heating　technology,　air　source　heat　pump　(ASHP)　has　been　widely　used　in　household　in　China.　However,　some　problems　occurred　with　the　commonly　used　water　loop　system,　such　as　low　efficiency,　complicated　structure,　more　likely　to　be　frozen　and　burst　as　well　as　high　electric　energy　consumption,　etc.　In　this　paper,　a　new　air　source　heat　pump　with　multigroup　heat　pipe　radiators　(ASHPMP)　was　presented.　In　ASHPMP　system,　the　condenser　and　heat　pipe　were　coupled　together　to　form　a　new　type　of　heat　radiation　terminal,　which　was　named　as　heat　pipe　radiators,　multiple　terminals　driven　by　the　compressor　provided　heat　for　several　rooms.　An　experimental　apparatus　of　the　ASHPMP　system　was　developed　and　the　experiment　was　carried　out　in　residential　buildings　also,　and　R410A　was　used　in　the　heat　pump　and　R134a　was　used　in　heat　pipes.　The　influence　of　temperature,　pressure　of　heat　pump　and　heat　pipe　on　the　heating　performance　of　ASHPMP　under　frosting/defrosting　condition　was　analysed.　The　results　showed　that　the　new　system　can　operate　stably　under　outdoor　temperatures　of　−12.7　°C　to　6.5　°C.　As　the　indoor　temperature　was　set　at　20　°C,　the　heating　coefficient　of　performance　(heating　COP)　could　reach　up　to　3.15　with　outdoor　temperature　−12.7　°C,　and　it　was　6.73　with　outdoor　temperature　6.5　°C.　©　2023　International　Solar　Energy　Society
