Claims (1)

[Scope of Claim for Utility Model Registration] 1. A humidity sensor installed on or near the windshield on the inside of a vehicle, and a humidity determination device that provides a predetermined output when the output of the humidity sensor exceeds a predetermined humidity determination set value. and a compressor operating means for obtaining an operating output or an operation stop output of the air conditioning control compressor according to the output of the humidity determining means, in a demist control device in a vehicle air conditioning control system, wherein the humidity determining means comprises: A balloon mode determining means for determining which mode the balloon mode is in, and a set value varying means for varying the humidity determination set value of the humidity determining means in accordance with the output of the balloon mode determining means. A demist control device for a vehicle air conditioning control system, characterized by: 2. The demist control device for a vehicle air conditioning control system according to claim 1, wherein each of the blowout modes is a vent mode, a bi-level mode, a foot mode, a foot/differential mode, and a differential mode. 3. The demist control device in a vehicle air conditioning control system according to claim 2, wherein the humidity determination set value decreases in the order of vent mode, bi-level mode, foot mode, foot/differential mode, and differential mode.
