Abstract:
An automotive climate control system comprising:an air-conditioning casing (11) for passing the air to be blown out into the cabin; a first heat exchanger (12) arranged in said air-conditioning casing (11) for exchanging heat between a refrigerant and the air; a face opening (17) arranged downstream of said first heat exchanger (12) in the air flow for blowing out the air to the faces of the occupants in the cabin; a foot opening (18) arranged downstream of said first heat exchanger (12) in the air flow for blowing out the air to the feet of the occupants in the cabin; a defroster opening (19) arranged downstream of said first heat exchanger (12) in the air flow for blowing out the air to the vehicle windshield glass; an internal air inlet (22) arranged upstream of said first heat exchanger (12) in the air flow for introducing the air from the cabin; and an external air inlet (23) arranged upstream of said first heat exchanger (12) in the air flow for introducing the air from outside the cabin; wherein when the electrical equipment mounted on the vehicle is not supplied with power, among a first air path (A) leading from the first heat exchanger (12) to the face opening (17), a second air path (B) leading from the first heat exchanger (12) to the foot opening (18) and a third air path (C) leading from the first heat exchanger (12) to the defroster opening (19), only the air path (C) having a larger air resistance than an air path (E) leading from the first heat exchanger (12) to the external air inlet (23) passes air therethrough while, at the same time, air is passed through the air path (E) leading from the first heat exchanger (12) to the external air inlet (23).
