Document Type and Number:
Japanese Patent JP2019099045
Kind Code:
A
Abstract:
To prevent a window glass from fogging even in a circumstance where a temperature detection sensor cannot support variation in temperature of the window glass.SOLUTION: A vehicle air conditioning device acquires variation in outside air temperature based on a detection result of an outside air temperature detection sensor. When variation in outside air temperature exceeds a predetermined level, the vehicle air conditioning device controls an inside/outside air switching damper so as to lower an upper limit of an inside air circulation amount as compared to that when the variation in outside air temperature is equal to or lower than the predetermined level.SELECTED DRAWING: Figure 12
