Air　conditioning　system　as　a　key　subsystem　of　environmental　regulation　within　the　entire　vehicle　system，the　carbon　emission　of　air　conditioning　system　throughout　its　entire　lifecycle　is　crucial　for　meeting　the　environmental　protection　and　emission　requirement　of　electric　vehicle.　Combining　the　life　cycle　climate　performance　（LCCP）model　of　electric　vehicle　air　conditioning　system　with　relevant　data，the　LCCP　values　in　different　provinces　of　China　are　analyzed　in　this　paper.　Besides，the　LCCP　values　under　two　different　heating　schemes　and　different　carbon　intensities　of　electricity　are　compared.　The　results　show　that　low-GWP　mixed　refrigerant　RE170/R134a（RE170　to　R134a　mass　fraction　ratio　90∶10）can　lead　to　a　decrease　in　LCCP　values　for　electric　vehicle　air　conditioning　system　by　11.2%　to　28.1%　in　China.　Replacing　the　PTC　heater　with　the　heat　pump　results　in　a　decrease　in　LCCP　values　by　0　to　33.1%.　In　addition，considering　the　future　changes　in　China＇s　carbon　intensity　of　electricity　and　the　proliferation　of　electric　vehicles，it　is　anticipated　that　the　LCCP　values　for　an　individual　vehicle　by　2035　will　decrease　by　31.7%　to　39.3%，while　the　gross　electric　vehicle　LCCP　values　in　China　will　increase　significantly.　©　2024　SAE-China.　All　rights　reserved.
