PURPOSE:To improve a demisting ability at the time of a low open air, by setting to values having a correlation with an open air temperature, a set value stopping a compressor, and the target cooling degree of an evaporator. CONSTITUTION:When an open air temperature is larger than a predetermined value by means of the 1st deciding means 100 which decides whether or not the open air temperature is larger than the predetermined value on the basis of the output of an open air temperature sensor 43, respective settings are done so that a thermo set value setting means 200 sets a thermo set value stopping a compressor 18 to a predetermined value and also, a target cooling degree setting means 500 sets the target cooling degree of an evaporator 8 to a predetermined value. Also, when the open air temperature is decided to be smaller than the predetermined value by means of the deciding means 100, respective settings are done so that the setting means 200 sets the thermo set value to a value having a correlation with the open air temperature, and also, the setting means 500 sets the target cooling degree of the evaporator 8 to a value having a correlation with the open air temperature. As a result, even if the evaporator 8 is frozen, a demisting control can be secured to the extent where there is no hindrance. |
