To　improve　the　thermal　performance　of　the　air-to-air　energy　recovery　devices　in　cold　climates,　especially　in　low　temperature　conditions,　a　novel　integrated　system　with　heat　recovery　combining　pump-driven　loop　heat　pipe　and　heat　pump　is　proposed　and　studied.　The　energy　recovery　device　can　operate　separately　at　three　modes:　pump-driven　loop　heat　pipe　mode,　heat　pump　mode　or　integrated　mode.　Results　show　that　the　temperature　effectiveness　and　energy　efficiency　ratio　of　the　integrated　system　are　higher　than　that　of　heat　pump　system　in　whole　conditions,　and　the　heat　transfer　capacity　of　the　integrated　system　has　a　positive　correlation　with　the　fresh　air　load.　In　addition,　the　system　can　switch　its　operating　modes　according　to　the　different　outdoor　temperature.　In　test　conditions,　when　outdoor　temperature　is　greater　than　8.7　degrees　C　or　lower　than　35.8　degrees　C,　heat　pump　system　performs　better,　otherwise　the　integrated　system　is　more　suitable.　Compared　with　others　systems,　the　novel　integrated　system　has　better　performance　in　all-year,　especially　in　low　temperature　conditions.　The　novel　integrated　system　shows　a　good　application　prospect　in　energy-saving　buildings.
