ABSTRACT:
There is used a refrigerant which is lower in a saturated water concentration in gas phase than in liquid phase, such as, for example, Freon-134a or Freon-22. In a body block 46 of a box-shaped expansion valve there are formed by-passes 77, 81 and 86 for by-passing a portion of the refrigerant evaporated in an evaporator 41. Halfway in the by-passes 77, 81 and 86 a cooling cylinder 73 is disposed for cooling the refrigerant present in those by-passes, and further a filter 83 is disposed for collecting the water contained in the refrigerant. In addition, a water permeating membrane 88 is disposed in a water discharge passage 79 formed in the body block 46.
