Document Type and Number:
WIPO Patent Application WO/2018/155871
Kind Code:
A1
Abstract:
Disclosed is a vehicle heat pump system using a water cooled condenser, in which a heating part and a heat sink part are separated so that engine waste heat can be independently used as only a heat source, and a high temperature coolant loop is additionally separated to decrease the length of a loop. The vehicle heat pump system includes: a first coolant line connecting a vehicle driving component to a chiller in order to circulate a coolant; a second coolant line connecting a heater core, which is disposed in an air conditioning case and used for heating the inside of the vehicle, to the water cooled condenser in order to circulate the coolant; and a valve provided between the first coolant line and the second coolant line. Here, when the valve is arranged in a first manner, the first coolant line and the second coolant line are operated separately, and, when the valve is arranged in a second manner, the first coolant line and the second coolant line are connected in series.
