VEHICLE AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/193897
Kind Code:
A1
Abstract:
This vehicle air conditioner is provided with an air conditioning case (10), a blower device (3), a cooling heat exchanger (4), a heating heat exchanger (6), an upward blowoff passage (80, 85), a foot blowoff passage (8c1), a bypass passage (10c), a switching unit (15) and a humidifier (9). The air conditioning case forms an inside air ventilation passage (10b) and an outside air ventilation passage (10a). The cooling heat exchanger cools inside air passing through the inside air ventilation passage and outside air passing through the outside air ventilation passage. The heating heat exchanger is arranged downstream of the cooling heat exchanger and heats inside air passing through the inside air ventilation passage and outside air passing through the outside air ventilation passage. The upward blowoff passage blows outside air that has passed through the outside air ventilation passage onto the upper body of the passenger. The bypass passage branches from the outside air ventilation passage upstream of the heating heat exchanger and merges with the upward blowoff passage. The switching unit switches the bypass passage between a communicating state and a cutoff state. The humidifier humidified air passing through the upward blowoff passage.
