VEHICLE AIR CONDITIONING DEVICE
In a vehicle air conditioner, air in the first flow path flows sequentially through outside air intake opening ( 112 ), blower fan ( 102 ), evaporator ( 103 ), condenser ( 104 ), and the inside of vehicle, and air in the second flow path flows sequentially through inside air intake opening ( 116 ), sensible heat exchanger ( 101 ), and the outside of the vehicle. Sensible heat exchanger ( 101 ) exchanges heat between outside air introduced from outside air intake opening ( 112 ) by the suction force of blower fan ( 102 ), and inside air passing through the first flow path and the inside of vehicle and introduced in the second flow path by the blowing force of blower fan ( 102 ). Sensible heat exchanger ( 101 ) uses drain hose ( 201 ) discharging drain water created in cooling the outside air by evaporator ( 103 ) to the outside of vehicle, to discharge the inside air for which heat was exchanged to the outside of vehicle.
1 . A vehicle air conditioning apparatus comprising:
an outside air inlet through which outside air is introduced from outside of a passenger compartment;
an inside air inlet through which inside air is introduced from inside of the passenger compartment;
a heat exchanger that exchanges heat between inside air introduced through the inside air inlet and outside air introduced through the outside air inlet;
a blower fan that blows outside air which has been subjected to heat exchange by the heat exchanger, or outside air introduced through the outside air inlet, or inside air introduced through the inside air inlet;
an evaporator that cools outside air or inside air blown by the blower fan; and
a condenser that heats the outside air or inside air cooled by the evaporator and sends the heated outside air or inside air toward the inside of the passenger compartment, wherein:
a first flow passage is formed through which outside air or inside air flows in the order of the blower fan, the evaporator, the condenser, and the inside of the passenger compartment;
a second flow passage is formed which is separated from the first flow passage, and through which inside air flows in the order of the inside air inlet, the heat exchanger, and the outside of the passenger compartment; and
the heat exchanger exchanges heat between outside air introduced through the outside air inlet by suction power of the blower fan, and inside air introduced into the second passage after passing through the first passage and the inside of the passenger compartment by a blowing force of the blower fan, and discharges inside air which has been subjected to heat exchange to the outside of the passenger compartment by using a drain hose provided for discharging drain water to the outside of the passenger compartment, the drain water being generated when outside air is cooled by the evaporator.
2 . The vehicle air conditioning apparatus according to claim 1 , wherein the heat exchanger is a sensible heat exchanger.
3 . A vehicle comprising the vehicle air conditioning apparatus according to claim 1 .
