<P>PROBLEM TO BE SOLVED: To effeciently heat the interior of a compartment with preventing a window from fogging. Ž<P>SOLUTION: An evaporator 18 includes: an upper stage 18A corresponding to a flow passage 68; and a lower stage 18B corresponding to a flow passage 70, both of which are integrally formed, and further includes: a sensing tube 76 arranged between the upper stage and the lower stage; and an sensing tube 78 installed on a refrigerant discharging side of the lower stage. The sensing tubes 76 and 78 are connected to an expansion valve 16 through a sensing tube changing-over valve 80. When the air conditioning device 10 is set to an outdoor air/indoor air double layer mode for introducing outdoor air into the flow passage 68 and indoor air into the flow passage 70, the expansion valve and the sensing tube 76 are made to communicated with each other through the sensing tube changing-over valve, and the zone downstream of the vicinity of the refrigerant discharging port at the upper stage becomes SH96B to prevent the indoor air from being cooled by a heater core. Thus, deterioration of heating efficiency is avoided when the window is prevented from fogging. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
