Abstract:
1. An auxiliary air conditioning apparatus for a vehicle, comprising: a blower unit, wherein a blower is provided therein to forcibly blow intake air; a temperature control unit fluid-connected to the blower unit in order to receive air blown from the blower unit, wherein the temperature control unit includes an evaporator and a heater therein and is connected to an air duct in order to exhaust air that is cooled by the evaporator or heated by the heater; an auxiliary temperature control unit fluid-connected to the blower unit to receive air blown from the blower unit and fluid-connected to the air duct, wherein the auxiliary temperature control unit includes a heat exchanger core provided therein, the heat exchanger core having a thermoelectric device and is connected to the air duct in order to exhaust air that is cooled or heated by the heat exchanger core; an auxiliary power supply supplying electrical power to the blower and the heat exchanger core; and an auxiliary cooling/heating control unit controlling operation of the blower and the heat exchanger core; wherein the temperature control unit and the auxiliary temperature control unit have separate air inlets and independent air passages from each other, and the blower unit includes a blower door capable of selectively opening the air inlet of the temperature control unit while closing the air inlet of the auxiliary temperature control unit or vice versa; wherein the auxiliary cooling/heating control unit is configured to cool or heat a cabin of the vehicle when an engine is stopped, by rotating the blower door to close the air inlet which is connected to the temperature control unit while opening the air inlet which is connected to the auxiliary temperature control unit, and at a same time, the auxiliary cooling/heating control unit controls the auxiliary power supply to supply electrical power to the blower and the heat exchanger core.
