Using　ambient　energy　to　cool　the　telecommunication　base　station　in　the　transitional　seasons　and　winter　is　an　effective　measure,　which　indicates　that　the　potential　of　energy　saving　is　considerable.　Based　on　the　analysis　of　the　energy　consumption　characteristics　and　environmental　requirements,　the　energy　consumption　model　is　set　up,　and　the　simulation　analysis　is　carried　out　under　different　conditions　in　the　typical　areas.　Taking　the　brick　wall　with　the　thicknesses　of　180,　240,　and　370　mm　and　the　polystyrene　sandwich　panel　of　50,　75,　and　100　mm　as　an　example,　the　room-base　temperature　is　analyzed,　the　air　conditioning　cooling　load　and　the　building　envelope　heat　dissipation　in　the　whole　year　are　simulated　under　different　environmental　control　temperatures,　the　effect　of　the　air　conditioning　system　coupled　with　a　thermosyphon　heat　exchanger　on　the　energy　consumption　of　the　communication　base　station　is　compared　with　that　of　the　air　conditioning　system,　and　the　energy　saving　effect　of　the　thermosyphon　heat　exchanger　is　also　discussed　in　different　areas.　Result　shows　that　higher　environmental　control　temperature　(25-28°C)　can　effectively　reduce　energy　consumption,　and　the　best　results　can　reach　16%.　Simulation　results　show　that　the　envelope　material　affects　the　air　conditioning　cooling　load　much.　For　brick　material　with　the　envelope　of　180　mm　in　thickness　performs　better　with　larger　heat　transfer　coefficient　and　is　propitious　to　dissipate　the　heat　of　the　base　station.　For　polystyrene　sandwich　panel　material　with　the　envelope　of　50　mm　in　thickness　performs　better.　Compared　with　the　air　conditioning　system,　the　air　conditioning　system　coupled　with　the　thermosyphon　heat　exchanger　obviously　saves　energy　with　the　rate　of　54.5%.
