In order to prevent it, a chocking device E or a capillary tube is interposed between the expansion valve C and an outdoor heat exchanger 6 at the outlet port of the expansion valve C. The heat shrinkable tube 1a is provided on the temperature sensitive unit 1 in such a manner and, therefore, the degree of overheating, in which the temperature of the superheat area has become more or less than 1 deg.C, may be changed.
