Patent ID: 8910489

Claim:
A heat pump system for a vehicle that includes a cooling module disposed in the vehicle to supply a motor and an electronic device with a coolant through a cooling line and an air conditioning module connected to a refrigerant line to control cooling and heating of an interior cabin of the vehicle, wherein the cooling module comprises: a radiator disposed at the front of the vehicle and through which the coolant is circulated along the cooling line by a water pump and that cools the coolant through heat exchange with outside air; a cooling fan disposed at the rear of the radiator; and a water cooled condenser connected to the cooling line to circulate the coolant, that selectively uses waste heat generated from the motor and the electronic device according to a driving mode to change the coolant temperature, and connected to a refrigerant line of the air conditioning module to make the inflow refrigerant exchange heat with the coolant, wherein the water cooled condenser is disposed between the radiator and the motor on the cooling line, and the cooling modules include a third valve that selectively bypasses the cooling line to supply the coolant to the radiator or directly to the water pump according to heating, cooling, and dehumidifying modes of the vehicle.
