A　pump-driven　loop　heat　pipe　(PLHP)　was　proposed　for　energy　recovery　from　exhaust　air　to　reduce　fresh　air　handling　energy　consumption　of　air　conditioning　systems.　The　influences　of　working　fluid,　mass　flow　rate,　heat　exchanging　area　and　facing　air　velocity　on　heat　transfer　capacity,　temperature　effectiveness　and　coefficient　of　performance　(COP)　were　studied　experimentally　under　different　working　conditions.　The　optimum　working　fluid　and　value　were　obtained,　respectively.　Results　indicate　that　the　heat　transfer　capacity　and　COP　increase　with　the　temperature　difference　between　indoor　and　outdoor　air　while　the　temperature　effectiveness　decreases.　The　general　performance　for　R32　as　working　fluid　was　better　than　R22　and　R152a.　For　summer　condition,　the　heat　transfer　capacity　was　4.09　kW　and　the　COP　was　9.26　when　the　mass　flow　rate　was　250　kg　h(-1),　the　heat　exchanging　area　was　58.0　m(2)　and　the　facing　air　velocity　was　1.8　ms(-1).　For　winter　condition,　the　heat　transfer　capacity　was　6.63　kW　and　the　COP　was　14.20　while　the　mass　flow　rate　was　300　kg　h(-1),　the　heat　exchanging　area　was　58.0　m(2)　and　the　facing　air　velocity　was　1.8　m　s(-1).　The　tested　device　could　meet　the　energy　recovery　need　with　remarkable　energy　savings.　(C)　2017　Elsevier　B.V.　All　rights　reserved.
