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.

A water removing device for removing water from a refrigerant for which saturated water concentration is lower in the gas phase than in a liquid phase comprising: a by-pass passage including a capillary tube for by-passing a part of the refrigerant evaporated in an evaporator; and a water collector

A water removing device for removing water from a refrigerant for which saturated water concentration is lower in the gas phase than in a liquid phase comprising: a by-pass passage including a capillary tube for by-passing a part of the refrigerant evaporated in an evaporator; and a water collector which is provided in the by-pass passage and connected to said capillary tube, said water collector being formed with an expansion chamber which causes adiabatic expansion of the refrigerant from said capillary tube to condense water and collect the water contained in the refrigerant.
