Air conditioner for vehicle

Abstract

An air conditioner for a vehicle provided with a cooling line which includes an evaporator core, a compressor, a condenser, and an expansion valve, may include a heater core provided between the compressor and the condenser on the cooling line, configured to be introduced with a refrigerant from the compressor, to have the refrigerant circulated therein, and to discharge the refrigerant to the condenser.

What is claimed is: 
     
         1 . An air conditioner for a vehicle provided with a cooling line which includes an evaporator core, a compressor, a condenser, and an expansion valve, the air conditioner comprising:
 a heater core provided between the compressor and the condenser on the cooling line, configured to be introduced with a refrigerant from the compressor, to have the refrigerant circulated therein, and to discharge the refrigerant to the condenser.   
     
     
         2 . The air conditioner of  claim 1 , wherein the heater core is provided between the condenser and the expansion valve on the cooling line, is introduced with the refrigerant from the condenser, has the refrigerant circulated therein, and discharges the refrigerant to the expansion valve. 
     
     
         3 . The air conditioner of  claim 1 , wherein the heater core has a high temperature and high pressure refrigerant compressed by the compressor circulated therein to heat conditioned air discharged to an interior of the vehicle. 
     
     
         4 . The air conditioner of  claim 1 , wherein conditioned air discharged into an interior of the vehicle is formed by selectively mixing air passing through the evaporator core with air passing through the heater core. 
     
     
         5 . The air conditioner of  claim 1 , further comprising:
 a cooling fan configured to condense the refrigerant in the condenser; and   a controller configured to stop an operation of the cooling fan in a heating mode.   
     
     
         6 . The air conditioner of  claim 5 , wherein the controller is configured to operate the compressor in the heating mode to compress the refrigerant at high temperature and high pressure. 
     
     
         7 . The air conditioner of  claim 1 , further comprising:
 a housing vertically provided with an inlet and an outlet and having the heater core and the evaporator core each disposed in a left and right space therein;   an inflow side door provided at a side of the inlet between the heater core and the evaporator core and configured to control a distribution amount of air introduced into the heater core and the evaporator core; and   an outflow side door provided at a side of the outlet between the heater core and the evaporator core and configured to control a mixed amount of air discharged from the heater core and the evaporator core.   
     
     
         8 . The air conditioner of  claim 2 , wherein the heater core has a high temperature and high pressure refrigerant compressed by the compressor circulated therein to heat conditioned air discharged to an interior of the vehicle. 
     
     
         9 . The air conditioner of  claim 2 , wherein conditioned air discharged into an interior of the vehicle is formed by selectively mixing air passing through the evaporator core with air passing through the heater core. 
     
     
         10 . The air conditioner of  claim 2 , further comprising:
 a cooling fan configured to condense the refrigerant in the condenser; and   a controller configured to stop an operation of the cooling fan in a heating mode.   
     
     
         11 . The air conditioner of  claim 10 , wherein the controller is configured to operate the compressor in the heating mode to compress the refrigerant at high temperature and high pressure. 
     
     
         12 . The air conditioner of  claim 2 , further comprising:
 a housing vertically provided with an inlet and an outlet and having the heater core and the evaporator core each disposed in a left and right space therein;   an inflow side door provided at a side of the inlet between the heater core and the evaporator core and configured to control a distribution amount of air introduced into the heater core and the evaporator core; and   an outflow side door provided at a side of the outlet between the heater core and the evaporator core and configured to control a mixed amount of air discharged from the heater core and the evaporator core.
