<p><P>PROBLEM TO BE SOLVED: To effectively prevent generation of dew condensation near a cooling portion while reducing a size and costs by simplifying a structure. <P>SOLUTION: This heat exchanging system comprises an outdoor heat exchanger 11, an indoor heat exchanger 12, a compressor 13 disposed on a first path PT1 and compressing a refrigerant, an electronic expansion valve 15 disposed on a second path PT2 in a state that its opening is controllable, and a cooling jacket 25 disposed on the second path PT2 and cooling a cooled object 30. The electronic expansion valve 15 has a two-stage throttle structure comprising a first throttle portion 21a and a second throttle portion 21b. The cooled object 30 is cooled by the cooling jacket 25 by the refrigerant passing through a path between the first throttle portion 21a and the second throttle portion 21b. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
