In　this　article,　a　new　evaporative　condenser　with　an　annular　elliptic　finned　tube　heat　exchanger　that　includes　a　round　inner　tube　and　elliptic　outer　finned　tube　was　designed　and　analyzed.　The　refrigerant　flows　between　the　round　inner　tube　and　the　elliptic　outer　tube,　and　it　simultaneously　exchanges　heat　with　the　cooling　water　in　the　inner　tube,　the　spray　water,　and　the　cooling　air　flowing　past　the　outer　tube.　Using　field　measurement　for　the　traditional　round　finned　tube　evaporative　condenser　in　the　Futong　Metro　Station　of　Line　14　in　Beijing,　China,　the　theoretical　heat　transfer　performance　of　the　annular　elliptic　finned　tube　evaporative　condenser　was　analyzed　and　simulated.　Compared　with　a　round　finned　tube　heat　exchanger,　the　heat　exchange　capacity　of　the　annular　elliptic　finned　tube　increased　by　2.34%　to　9.28%;　the　total　heat　transfer　coefficient　increased　by　47.42%,　and　the　power　consumption　of　the　fan　in　the　air-conditioning　system　with　an　annular　elliptic　finned　tube　heat　exchanger　decreased　by　11.18%　to　14.65%.　Therefore,　the　energy-saving　performance　and　the　heat　transfer　performance　of　the　new　annular　elliptic　finned　tube　heat　exchanger　were　enhanced　compared　to　the　round　finned　tube　heat　exchanger.
