In　order　to　improve　the　temperature　efficiency　of　the　pump-driven　loop　heat　pipe　system　and　explore　the　technical　feasibility　of　replacement　of　the　single-loop　pump-driven　loop　heat　pipe　system　by　the　multi-loop　pump-driven　loop　heat　pipe　system　for　energy　recovery　from　exhaust　air　in　public　buildings,　a　single-loop　and　a　triple-loop　pump-driven　loop　heat　pipe　system　prototype　were　developed.　An　experimental　setup　was　built　to　contrast　the　heat　transfer　characteristics　between　the　single-loop　system　and　the　triple-loop　system　under　summer　and　winter　working　conditions　based　on　the　principle　of　heat　transfer　temperature　difference　uniformity.　Results　indicated　that　performance　of　the　triple-loop　system　was　better.　Compared　with　the　single-loop　system,　the　temperature　efficiency　of　the　triple-loop　system　was　improved　by　22.6%　under　winter　working　condition　when　the　temperature　difference　between　indoor　and　outdoor　air　was　31.9　because　the　temperature　difference　uniformity　was　much　better,　while　the　temperature　efficiency　changed　little　under　summer　working　condition.　©　All　Right　Reserved.
