PROBLEM TO BE SOLVED: To prevent frost from adhering to a tube and growing. SOLUTION: A cross sectional shape of the tube 131 is a streamlined shape. Consequently, since air flowing around the tube 131 flows smoothly without stagnating, a water drop which forms a start point for the growth of frost does not occur on a surface of the tube 131. As a result, it is possible to prevent frost from adhering to the tube 131, namely, an evaporator 13 and growing. COPYRIGHT: (C)2004,JPO
