 a door allowing the first air passageway and the indoor circulation passage to communicate with each other and the second air passageway and the outdoor discharge passage to communicate with each other or allowing the first air passageway and the outdoor discharge passage to communicate with each other and the second air passageway and the indoor circulation passage to communicate with each other.   
     
     
         19 . The air conditioner according to  claim 18 , wherein the first blower and the second blower are disposed at the downstream side of the door in an air flow direction. 
     
     
         20 . The air conditioner according to  claim 17 , wherein the second blower is higher in air volume than the first blower. 
     
     
         21 . The air conditioner according to  claim 17 , wherein indoor air and outdoor air are selectively supplied to the evaporator and the condenser, and the indoor air exchanges heat with the evaporator and is supplied to the interior of the vehicle and the outdoor air exchanges heat with the condenser and is discharged to the outside of the vehicle in a cooling mode, and the indoor air exchanges heat with the condenser and is supplied to the interior of the vehicle and the outdoor air exchanges heat with the evaporator and is discharged to the outside of the vehicle in a heating mode. 
     
     
         22 . The air conditioner according to  claim 17 , further comprising:
 a compressor which compresses refrigerant passing through the evaporator and discharges the compressed refrigerant to the condenser, wherein the compressor is arranged on the air passageway on which the condenser is arranged.   
     
     
         23 . The air conditioner according to  claim 22 , wherein the compressor is disposed at the downstream side of the condenser in the air flow direction. 
     
     
         24 . An air conditioner for a vehicle comprising:
 an air-conditioning case having a first air passageway and a second air passageway;   an evaporator disposed on the first air passageway or the second air passageway; and   a condenser disposed on the first air passageway or the second air passageway,   wherein the air passing through the condenser flows to an outdoor discharge passageway only in a first air-conditioning mode.   
     
     
         25 . The air conditioner according to  claim 24 , further comprising:
 an auxiliary outdoor discharge passage, which bypasses the air passing through the condenser to the outdoor discharge passage to discharge the air to the outside,   wherein the air passing through the condenser is discharged through the auxiliary outdoor discharge passage in a second air-conditioning mode.   
     
     
         26 . The air conditioner according to  claim 24 , wherein the first air-conditioning mode is a heating mode, and the second air-conditioning mode is a cooling mode. 
     
     
         27 . The air conditioner according to  claim 25 , further comprising:
 a bypass door which controls the air passing through the condenser to pass the auxiliary outdoor discharge passage or bypass the auxiliary outdoor discharge passage.   
     
     
         28 . The air conditioner according to  claim 27 , further comprising:
 an electric heater disposed on the air passageway on which the condenser is arranged,   wherein the electric heater is arranged at the downstream side of the bypass door in the air flow direction.   
     
     
         29 . The air conditioner according to  claim 28 , further comprising:
 a door allowing the first air passageway and the indoor circulation passage to communicate with each other and the second air passageway and the outdoor discharge passage to communicate with each other or allowing the first air passageway and the outdoor discharge passage to communicate with each other and the second air passageway and the indoor circulation passage to communicate with each other,   wherein the electric heater is arranged between the door and the bypass door.   
     
     
         30 . The air conditioner according to  claim 17 , wherein the first blower and the second blower are arranged at right angles to each other. 
     
     
         31 . The air conditioner according to  claim 30 , wherein a rotary shaft of a first blower fan and a rotary shaft of a second blower fan are arranged at right angles to each other. 
     
     
         32 . The air conditioner according to  claim 31 , wherein the first blower and the second blower are arranged at the downstream side of the evaporator and the condenser in the air flow direction, and are formed in a suction type to inhale air.
