摘要：

The　efficiencies　of　single　screw　expander　and　multi-stage　centrifugal　pump　are　obtained　by　fitting　experimental　data,　and　which　substitute　the　constant　efficiencies　of　the　expander　and　the　pump　in　most　researches.　Modelling　analysis　of　four　configurations　of　organic　Rankine　cycle　system　(conventional　organic　Rankine　cycle,　organic　Rankine　cycle　with　a　regenerator,　extraction　organic　Rankine　cycle　and　extraction　organic　Rankine　cycle　with　a　regenerator)　is　conducted,　the　effects　of　evaporation　pressure　and　condensation　temperature　on　the　thermal　efficiency　of　different　cycle　configurations　are　investigated　and　compared.　Extraction　pressure　and　extraction　ratio　are　introduced　to　analyze　the　thermal　efficiency　of　the　latter　two　cycle　configurations.　Result　shows　that　the　extraction　organic　Rankine　cycle　with　a　regenerator　has　the　highest　thermal　efficiency　at　the　same　operation　condition;　evaporation　pressure　has　a　positive　effect　on　the　thermal　efficiency,　while　condensation　temperature　has　a　negative　effect　under　a　certain　range.　This　study　can　provide　a　reference　for　the　selection　of　the　cycle　configuration　and　design　of　operation　parameters　for　a　given　system.　©　Springer　Nature　Switzerland　AG　2020.
