Abstract

A radiant heater air-conditioning system includes: a heater main body having a heating portion energized to generate heat so as to radiate a radiant heat into a vehicle interior; an energization setting unit that sets an energization enable state for enabling energization of the heating portion and an energization disable state for disabling the energization of the heating portion; and an air-conditioning control apparatus that controls an air-conditioning output of a heating operation in the vehicle interior. The air-conditioning control apparatus reduces the air-conditioning output when the energization enable state is set, compared with when the energization disable state is set.

Claims

a heater main body having a heating portion energized to generate heat so as to radiate a radiant heat into a vehicle interior;

an energization setting unit that sets an energization enable state for enabling energization of the heating portion and an energization disable state for disabling the energization of the heating portion;

an air-conditioning control apparatus that controls an air-conditioning output of a heating operation in the vehicle interior;

a specific seat switch operated to set a specific seat mode for performing air-conditioning on a predetermined seat preferentially, the specific seat switch includes a one-seat concentration switch operated by an occupant to set one of a front driver seat, a front passenger seat, and rear seats as the predetermined seat, wherein

the air-conditioning control apparatus reduces the air-conditioning output when the energization enable state is set, compared with when the energization disable state is set, and

the air-conditioning control apparatus reduces the air-conditioning output to a seat other than the predetermined seat when the energization enable state is set and when the specific seat mode is set, compared with when the energization disable state is set.
