1. An integrated thermal management system for a vehicle, comprising:
a refrigerant flow line extending to allow a refrigerant discharged from a compressor to flow in an order of an indoor condenser, an external condenser, and an evaporator and to flow back to the compressor;
a plurality of refrigerant chiller lines branching from the refrigerant flow line at a point downstream of the compressor, a point downstream of the indoor condenser, or a point downstream of the external condenser, the refrigerant chiller lines joining the refrigerant flow line at a point upstream of the compressor after the refrigerant, flowing in each of the refrigerant chiller lines branching therefrom, passes through a battery chiller and an electric chiller or bypasses the battery chiller and the electric chiller;
a battery cooling line extending to allow a coolant, passing through a battery and being discharged therefrom, to circulate while passing through a battery radiator or the battery chiller; and
an electric cooling line extending to allow the coolant, passing through an electric component and being discharged therefrom, to circulate while passing through an electric radiator or the electric chiller,
wherein the refrigerant chiller lines comprise an integrated valve connected to the point downstream of the compressor, the point downstream of the indoor condenser, or the point downstream of the external condenser so that the refrigerant in the refrigerant flow line flows thereinto, and connected to the point upstream of the compressor by passing through or bypassing the battery chiller and the electric chiller so that the refrigerant flowing thereinto is discharged to the refrigerant flow line,
wherein the system further comprises a controller configured to control operation of the compressor, to control the integrated valve to regulate flow of the refrigerant in the refrigerant flow line or the refrigerant chiller lines, and to control flow of the coolant in the battery cooling line or the electric cooling line,
wherein the controller, in a battery waste heat absorption heating mode, permits flow of the coolant so that the coolant, passing through the battery and being discharged therefrom in the battery cooling line, circulates while passing through the battery chiller, controls the integrated valve so that the refrigerant in the refrigerant flow line flows into the refrigerant chiller lines at the point downstream of the indoor condenser or at the point downstream of the external condenser and is discharged to the refrigerant flow line at the point upstream of the compressor via the battery chiller and the electric chiller through the refrigerant chiller lines, and absorbs waste heat of the battery by expanding the refrigerant at a point upstream of the battery chiller on the refrigerant chiller lines.
