摘要：

An　organic　Rankine　cycle　system　with　recuperator　was　designed　for　recycling　waste　heat　of　a　vehicle　diesel　engine　and　R245fa　was　used　as　working　medium.　The　change　of　waste　heat　from　vehicle　diesel　engine　under　variable　working　conditions　was　studied.　The　operating　performance　of　the　organic　Rankine　cycle　system　with　recuperator　was　analyzed　under　variable　working　conditions　and　the　influence　of　degree　of　superheat　on　the　organic　Rankine　cycle　system　with　recuperator　was　discussed.　Three　evaluation　indices,　waste　heat　recovery　efficiency　(WHRE),　engine　thermal　efficiency　increasing　ratio　(ETEIR)　and　output　energy　density　of　working　fluid　(OEDWF)　were　presented　for　the　vehicle　diesel　engine-organic　Rankine　cycle　combined　system.　The　net　power　output,　WHRE　and　ETEIR　could　reach　maximum　values　of　43.74　kW,　14.93%　and　13.58%.　©,　2015,　Chemical　Industry　Press.　All　right　reserved.
