The　air　conditioning　energy　consumption　for　fresh　air　handling　in　buildings　increases　yearly,　especially　in　low　energy　buildings.　This　energy　consumption　can　be　greatly　reduced　when　exhaust　air　is　recovered　for　preheating　or　precooling　fresh　air.　Then,　significant　savings　in　the　total　energy　consumption　in　buildings　will　be　achieved,　which　in　turn　helps　achieve　the　carbon　peak　in　the　building　field.　In　this　paper,　a　booster/pump　coupled　energy　recovery　ventilator　is　proposed　for　energy　recovery　in　buildings.　The　system　performance,　which　depends　on　the　loop　number　and　combination　strategies　were　analyzed　and　compared　through　model　simulations.　Results　indicate　that　the　heat　transfer　rate　of　different　coupling　systems　increases　with　the　temperature　difference.　In　summer,　the　pump/booster　driven　dual-loop　system　has　the　highest　average　temperature　effectiveness　of　47.3%　and　average　heat　transfer　rate　of　4.97　kW.　The　booster/booster-driven　dual-loop　system　has　the　highest　average　heat　transfer　rate　of　5.07　kW　and　average　temperature　effectiveness　of　47.1%.　The　average　temperature　effectiveness　of　the　pump/booster/booster　driven　triple-loop　system　reaches　up　to　45%　and　average　heat　transfer　rate　of　4.73　kW.　The　booster/booster/booster-driven　triple-loop　system　has　the　highest　average　heat　transfer　rate　of　4.82　kW　and　average　temperature　effectiveness　of　44.7%.　In　winter,　the　maximum　average　heat　transfer　rate　and　temperature　effectiveness　of　the　pump/booster　driven　dual-loop　system　are　8.54　kW　and　44.44%,　respectively.　The　maximum　average　heat　transfer　rate　and　temperature　effectiveness　of　the　pump/booster/booster　driven　triple-loop　system　are　7.90　kW　and　41.5%,　respectively.　Throughout　the　year,　the　best　coupling　scheme　of　the　dual-loop　system　is　the　pump/booster　driven　dual-loop　system,　and　its　average　heat　transfer　rate　and　temperature　effectiveness　are　6.755　kW　and　45.85%,　respectively.　The　best　coupling　scheme　of　the　triple-loop　system　is　the　pump/booster/booster-driven　triple-loop　system,　and　its　average　heat　transfer　rate　and　temperature　effectiveness　are　6.315　kW　and　43.25%,　respectively.　©　2023
