Air-conditioning apparatus for vehicle
View Patent ↗An air-conditioning apparatus for a vehicle includes an air-conditioning duct that includes an air supply path through which air to be supplied into an interior of the vehicle passes, a first tank to which a cool medium and a warm medium for adjusting the temperature of a first intermediate medium are supplied, a first heat exchanger that is provided in the air-conditioning duct and through which the first intermediate medium circulates from the first tank, and a controller that controls the first intermediate medium to a temperature needed to set the interior to a desired temperature.
1. An air-conditioning apparatus for a vehicle, comprising:
an air-conditioning duct that includes an air supply path,
wherein the air supply path is configured to pass air to be supplied to an interior of the vehicle;
a first tank configured to store a first intermediate medium, and to which a first cool medium and a first warm medium to adjust a temperature of the first intermediate medium are supplied;
a first heat exchanger that is provided in the air-conditioning duct and through which the first intermediate medium circulates from the first tank;
a second heat exchanger that is juxtaposed below the first heat exchanger in the air supply path of the air-conditioning duct and through which the first intermediate medium circulates from the first tank
a second tank configured to store a second intermediate medium, and to which a second cool medium and a second warm medium to adjust a temperature of the second intermediate medium are supplied;
a third heat exchanger that is provided, in the air-conditioning duct, upstream of both the first heat exchanger and the second heat exchanger, and wherein the second intermediate medium circulates from the second tank through the third heat exchanger; and
a controller configured to:
control the first intermediate medium to set a temperature of the interior of the vehicle to a desired temperature;
control the second intermediate medium to a dehumidification temperature; and
pass the first intermediate medium in a larger amount through the second heat exchanger than through the first heat exchanger.
2. The air-conditioning apparatus for a vehicle according to claim 1 , wherein the air-conditioning duct includes:
an upper blowout path configured to blow out the air toward an upper portion or a glass surface of the interior of the vehicle, and
a lower blowout path that is provided below the upper blowout path and is configured to blow out the air toward a lower portion of the interior of the vehicle,
the first heat exchanger is provided in the air supply path, where the first intermediate medium flows from bottom toward top, and
the second heat exchanger is provided in the air supply path, where the second intermediate medium flows from top toward bottom.
3. The air-conditioning apparatus for a vehicle according to claim 1 , further comprising:
an interior circulation path configured to allow the first intermediate medium to circulate between the first tank and the interior of the vehicle.
4. The air-conditioning apparatus for a vehicle according to claim 2 , further comprising:
an interior circulation path configured to allow the first intermediate medium to circulate between the first tank and the interior of the vehicle.
