Embodiment Construction

[0032] Below, refer to Figure 1 to Figure 4 The vehicle air conditioner 10 according to the embodiment of the present invention will be described.

[0033] The vehicle air-conditioning apparatus 10 is arranged at a substantially central portion in the vehicle width direction on the front side of the vehicle. Such as Figure 1 to Figure 3 As shown, the vehicle air conditioner 10 is integrally equipped with: an air introduction unit 11 such as a blower unit for introducing air, a heat exchange unit 12 for exchanging heat with the air flow of the introduced air, and an air flow from the inside of the heat exchange unit 12 to the interior of the vehicle compartment. Each part of the air flow path 13 is provided continuously.

[0034] The heat exchange unit 12 includes an evaporator 14 and a heater core 15 arranged downstream of the evaporator 14 in the casing 40 .

[0035] In the evaporator 14 , the refrigerant circulates between a radiator (not shown) and the like, and cools ...

Abstract

A rear-side flow channel (17) is provided with a rear-side duct (19), a first communication channel (21), a second communication channel (22), a first damper (23), and a second damper (24). The rear-side duct (19) extends from downstream of a heater core (15) toward the rear of a passenger cabin. The first communication channel (21) communicates the downstream of an evaporator (14) and a front-side flow channel. The second communication channel (22) communicates the downstream of the evaporator (14) and the downstream of the heater core (15). The first damper (23) can selectively guide an airflow to the first communication channel (21) or the second communication channel (22). The second damper (24) changes the communication state between a downstream opening (15b) of the heater core (15), the rear-side duct (19), and the second communication channel (22).

Description

technical field [0001] The present invention relates to a vehicle air conditioner mounted on a vehicle. [0002] This application claims priority based on Japanese Patent Application No. 2017-107108 for which it applied in Japan on May 30, 2017, and uses the content here. Background technique [0003] There is known a vehicle air-conditioning apparatus that includes an evaporator and a heater core disposed downstream of the evaporator, and blows air mixed with cool air from the evaporator and warm air from the heater core into the vehicle compartment. [0004] In the vehicle air-conditioning apparatus of Patent Document 1, the flow rate of warm air and the flow rate of cold air are individually adjusted by a damper or the like, thereby adjusting the mixing ratio of warm air and cold air. The mixed air of warm air and cold air is blown out from the feet and face on the front side of the car and the feet and face on the rear side of the car. The air conditioning of the cabin...
