The present invention relates to a refrigerant module for a heat pump system, capable of reducing occurrence of a loss and a thermal loss. According to the present invention, the refrigerant module for a heat pump system of a vehicle changes a flow direction of a refrigerant and expands the moved refrigerant by being connected to an inner condenser, an outer condenser, an evaporator, and an accumulator of a heat pump system for a vehicle. Moreover, the refrigerant module for a heat pump system of a vehicle can exchange heat of the refrigerant and the heat of coolant. The refrigerant module for a heat pump system of a vehicle includes: a manifold body connected to the indoor condenser, the outer condenser, the evaporator, and the accumulator and having an inner flow path unit and a valve flow path unit connected to the inner flow path unit, wherein the inner flow path unit guides the refrigerant so that the refrigerant flows therein; a water cooling type condenser connected to and installed in the manifold body to be connected to the inner flow path unit, wherein the water cooling type condenser exchanges the heat of the coolant flowing to a coolant line and the heat of the refrigerant flowing to the inner flow path unit; a battery chiller connected to and installed in the manifold body to be connected to the inner flow path unit, wherein the battery chiller cools the coolant of a battery by heat exchange with the refrigerant; an expansion valve unit connected to the valve flow path unit and depressurizing the refrigerant flowing to the water cooling type condenser, the outer condenser, the inner condenser, the battery chiller, and the evaporator; and an opening and closing valve unit connected to and installed in the valve flow path unit and changing the flow of the refrigerant flowing into the inner flow path unit.
