摘要： Vehicular air conditioning system improving the ease of assembly and the maintainability of a photocatalyst module by structural improvement of an intake case and suppressing an air vortex generated at the air intake side during air intake process in a blower and a rumbling noise caused by the air vortex.
The vehicular air conditioning system includes an intake part configured to suck indoor or outdoor air and blow air into a vehicle interior, a photocatalyst module purifying the air by emitting superoxide radicals toward the air blown into the vehicle interior from the intake part, which is installed on a downstream outer surface portion of a blower casing of the intake part, and an interference avoidance groove for avoiding interference with the photocatalyst module is formed on an outer surface portion of the intake case corresponding to the periphery of the photocatalyst module installed in the blower casing.
