1. A heat management system for an electric vehicle,
the system comprising:
an inner condenser mounted inside an air conditioner casing and connected to a discharge portion of an electric compressor by a first refrigerant flow path;
a first three-way expansion valve connected to the inner condenser by a second refrigerant flow path;
an outer condenser connected to a 1-1 outlet of the first three-way expansion valve by a third refrigerant flow path;
a second three-way expansion valve connected to the outer condenser by a fourth refrigerant flow path;
an expansion valve connected to a fifth refrigerant flow path branched off from the fourth refrigerant flow path;
an evaporator mounted inside the air conditioner casing and connected to the expansion valve by a sixth refrigerant flow path;
a seventh refrigerant flow path connected between a 1-2 outlet of the first three-way expansion valve and the sixth refrigerant flow path;
an accumulator connected to the evaporator by a refrigerant return flow path and connected to an inlet portion of the electric compressor;
an eighth refrigerant flow path connected between a 2-1 outlet of the second three-way expansion valve and the refrigerant return flow path;
a battery chiller connected to a 2-2 outlet of the second three-way expansion valve by a ninth refrigerant flow path; and
a tenth refrigerant flow path connected between the battery chiller and the refrigerant return flow path.
