Air conditioner system for electric motor vehicles

An air conditioner system for an electric motor vehicle, the air conditioner system comprising:

• a refrigerant line through which a refrigerant circulates and comprising a compressor, a condenser, an expander, and an evaporator;
• a coolant line through which a coolant circulates and comprising:
• a dehumidifying heat exchanger configured to remove moisture from conditioning air,
• a radiator heat exchanger,
• an electric device including a motor, and
• a switching valve configured to switch a flow direction of the coolant based on whether the dehumidifying heat exchanger performs dehumidification or regeneration, wherein the coolant flowing through the radiator heat exchanger or the coolant flowing through the electric device is directed into the dehumidifying heat exchanger;
• an air line configured to cause air to selectively pass through the dehumidifying heat exchanger or the evaporator, and configured to cause the air having passed through at least one of the dehumidifying heat exchanger, the condenser, or the evaporator to be selectively supplied to an interior of the electric motor vehicle,
• wherein the air line comprises:
• a first line comprising a first blower configured to circulate air and extending to an exterior while passing through the dehumidifying heat exchanger;
• a second line comprising:
• a second blower configured to circulate air, and a temperature control valve configured to cause the air to selectively pass through the evaporator or the condenser;
• and
• a third line branching from a downstream end of the dehumidifying heat exchanger of the first line through a first shunt valve and connected to an upstream end of the evaporator through a second shunt valve;
• and
• a heat exchanging line through which external air circulates, wherein the heat exchanging line comprises an external heat exchanger configured to cause the refrigerant of the refrigerant line to exchange heat with the external air, and is connected to the radiator heat exchanger of the coolant line to cause the external air to exchange heat with the coolant of the coolant line.
