Abstract
An air conditioning apparatus for electric motor vehicles includes a sub-heat exchanger provided between a heat exchanger and an electric heater, and the sub-heat exchanger is moved towards the heat exchanger or the electric heater so that heat is conducted to the sub-heat exchanger depending on whether or not the heat exchanger and the electric heater are operated depending on a heating condition, thereby increasing a heat dissipation area through the sub-heat exchanger during heating and thus being capable of improving heating performance.
