Abstract
A heat pump system and a method for operating this system type includes a heat pump circuit for a heat pump circuit medium flowing through a primary side of a heat exchanger, and a heating circuit for a heating circuit medium flowing through the heat exchanger secondary side. A heat circuit pump is connected upstream of the exchanger secondary side when viewed in the heating circuit medium operating flow direction. When viewed in the heating circuit medium operating flow direction, a check valve connected downstream of the heating circuit pump and upstream of the secondary side closes when a heating circuit medium flows opposite the operating flow direction, and a degassing unit connected downstream of the secondary side when viewed in the operating flow direction prevents a flow of the heating circuit medium in the operating flow direction from a predefined gas amount in the heating circuit medium.
