摘要：

In　order　to　improve　the　operation　efficiency　of　ground　source　heat　pump,　this　article　carried　out　performance　tests　on　actual　ground　source　heat　pump　system　under　different　refrigerant　charge　quantity　of　R22　from　external　water　circle　side　and　inner　refrigerant　side　simultaneously.　This　article　analyzed　the　performance　states　of　ground　source　heat　pump　and　the　reasons　from　thermodynamics　and　system　theory,　and　determined　the　degree　of　influence　of　refrigerant　charge　quantity　on　the　performance　of　ground　source　heat　pump　system,　finally　provided　the　optimal　refrigerant　charge　quantity.
