PURPOSE: To improve cooling capacity by providing first and second condensers connected to a compressor in parallel, setting the line length of the second condenser for supercooling refrigerant longer than that of the first condenser, and arranging the refrigerant pipe line so as to be converted from the windward side to the leeward side.
CONSTITUTION: The discharge pipe 12 of a compressor driven by an automobile engine is connected to the refrigerant inlet side of first and second condensers 13, 14, and the refrigerant outlet side of the first condenser 13 is connected to the refrigerant inlet pipe 16 of a liquid receiver 15. The refrigerant outlet pipe 17 of the liquid receiver 15 and a refrigerant outlet pipe 18 connected to the refrigerant outlet side of the second condenser 14 are connected to an expansion valve through a confluent pipe, and then connected to an evaporator. In this case, the refrigerant pipe lines 25 of the respective condensers 13, 14 are arranged so that the refrigerant flows meanderingly from the inlet side to the outlet side, from the leeward side to the windward side, and the refrigerant pipe line 25 of the second condenser 14 longer than that of the first condenser 13 is arranged on the windward side of the first condenser 13.
