<P>PROBLEM TO BE SOLVED: To simplify design by cooling a cooling air heat exchanger of an air-conditioning system in an aircraft and a heat exchanger cooling a coolant for power electronics by a simple cooling air ram. <P>SOLUTION: This aircraft air-conditioning system 20 has the cooling air ram, and this ram has an inlet 23, an outlet 24 and a fan 22, and also has a plurality of air heat exchangers and liquid sink heat exchangers 40 in the cooling air ram. Air sucked by the fan 22 cools the plurality of these heat exchangers. All the necessities for dividing a ram circuit are eliminated by using arrangement of incorporating the liquid sink heat exchangers 40 into the cooling air ram together with the plurality of air heat exchangers. <P>COPYRIGHT: (C)2007,JPO&INPIT |
