PURPOSE: A vehicle refrigerator is provided to operate refrigerator in a normal manner without installing an additional heat exchanger to the refrigerator by feeding condensate water and cooling air generated from a vehicle heat exchanger to the vehicle refrigerator and allowing the condensate water and cooling air to circulated through the circulation coil installed to the vehicle refrigerator. CONSTITUTION: A vehicle refrigerator(1) has a circulation coil(3) for circulation of refrigerant, and the circulation coil has a drain valve(4) formed at an end of the circulation coil. An evaporator(2) of a heat exchanger has a drain pan(5) arranged in the lower portion of the evaporator so as to collect the condensate water generated from the evaporator. The drain pan is connected to the circulation coil through a connection pipe(6), and a pump(8) is installed to the connection pipe. A bypass pipe is arranged between the evaporator and pump so as to allow the refrigerant circulating through the evaporator to be by-passed and applied to the circulation coil. Thus, the cooling air generated from the evaporator is fed to the circulation coil, to thereby lower the temperature of refrigerator without installing an additional heat exchanger to the refrigerator.
