Abstract
In a vehicle air conditioning system, a non-contact temperature sensor having plural temperature detecting elements is disposed to detect a predetermined region within a passenger compartment. The plural temperature detecting elements are constructed by plural first elements each of which has a smaller temperature detecting area in the predetermined region, and plural second elements each of which has a larger temperature detecting area in the predetermined region. The non-contact temperature sensor detects an area, where a detail temperature-distribution information is necessary, using the first elements, and detects an area, where the detail temperature-distribution information is unnecessary, using the second elements.
