The　outdated　structures　and　heating　devices　in　old　residential　buildings　can　no　longer　functionally　meet　the　thermal　needs　of　users　and　require　reasonable　supplementary　measures　to　meet　the　demand.　Personalized　local　heating,　owing　to　its　thermal　comfort　and　energy-saving　performance,　is　a　good　solution　for　addressing　the　thermal　needs　of　occupants.　The　objective　of　this　study　was　to　examine　the　influence　of　personalized　local　heating　on　the　thermal　comfort　of　occupants　in　old　residential　buildings　under　low-temperature　heating.　A　field　study　was　conducted　with　16　participants　in　typical　old　residential　buildings　under　different　conditions　from　January　to　February　2023.　The　findings　revealed　that　all　personalized　local　heating　methods　could　increase　the　overall　thermal　sensation　of　participants　at　background　temperatures　of　16　degrees　C　and　19　degrees　C,　but　only　a　few　of　them　were　effective　in　enhancing　the　participants＇　overall　thermal　comfort.　Regardless　of　the　chosen　localized　heating　method,　the　participants＇　thermal　acceptance　vote　varied　over　time.　When　using　localized　heating,　there　were　differences　in　the　body　parts　selected　for　heating　among　participants　at　16　degrees　C　and　19　degrees　C.　The　analysis　showed　that　the　corrective　power　of　heating　devices　for　human　thermal　comfort　is　related　to　the　background　environ-ment　temperature,　with　stronger　corrective　power　shown　at　lower　temperatures.　Furthermore,　as　long　as　the　problem　of　uneven　local　heating　was　effectively　resolved,　radiant　devices　were　the　preferred　environmental　conditioning　devices.　This　study　provides　important　guidance,　both　for　improving　thermal　comfort　in　old　resi-dential　buildings　and　for　expanding　the　application　of　personalized　local　heating.
