Prevention of frost formation on the refrigerant evaporator by intermittent operation of the refrigerant compressor based on an input signal from a temperature sensing element that detects the temperature on or near the outlet side of the refrigerant evaporator. A first control device performs control, and arithmetic processing is performed on signals from the temperature sensing element, room temperature sensor, outside temperature sensor, temperature setting device, etc. to control the opening degree of the air mix damper and the rotation speed of the blower. a second control device, and a switching unit for switching between outputting the signal from the temperature sensing element to the first control device or to the second control device. Features of vehicle air conditioning control equipment. 2. The air conditioning control device for a vehicle according to claim 1, characterized in that a relay is used as the switching section. 3. The air conditioning control device for a vehicle according to claim 1, wherein the switching unit is activated in conjunction with opening and closing of a starting switch for the refrigerant compressor. 4 When the signal from the temperature sensing element is output to the first control device by activation of the switching unit, the second control device outputs a signal of a predetermined constant value from the temperature sensing element. 2. The vehicle air conditioning control device according to claim 1, wherein the air conditioning control device performs arithmetic processing as a substitute for the signal.
