A vehicle comprising an air conditioning unit, comprising: a first air duct provided on one side of a partition panel (2DB1), a second air duct provided on the other side of the partition panel (2DB1), a first fan disposed in the first air duct, a second fan disposed in the second air duct, a rotating machine for rotating the first fan and the second fan in the same direction, a first heat exchanger having an upstream heat exchange part and a downstream heat exchange part, wherein; the upstream heat exchange part is located between the first fan and an outside air inlet so that air outside the vehicle flowed in from the outside air inlet is flowable through the upstream heat exchange part by the rotation of the first fan, the downstream heat exchange part is located between the first fan and a vehicle compartment outlet, so that the air outside the vehicle flowed in from the first fan is flowable through the downstream heat exchange part, the first heat exchanger is configured such that the flow of air outside the vehicle compartment flowing through the upstream heat exchange part and the flow of air outside the vehicle compartment flowing through the downstream heat exchange part are opposite flows, and a second heat exchanger is configured such that the air outside the vehicle compartment is flowable from the first fan through the downstream heat exchange part through the second heat exchanger, the first heat exchanger is an orthogonal heat exchanger configured to exchange heat as the inside air and outside air flow without being mixed and flow in cross, the second heat exchanger is a heat exchanger that is a component of a refrigeration cycle execution system, and the air conditioning unit is configured such that air in the vehicle compartment, which flows in from an inside air inlet by the rotation of the second fan and is discharged from an outlet to the outside of the vehicle, is flowable through the first heat exchanger exchanging heat with the air outside the vehicle compartment flowing through the first heat exchanger. a first air duct provided on one side of a partition panel (2DB1), a second air duct provided on the other side of the partition panel (2DB1), a first fan disposed in the first air duct, a second fan disposed in the second air duct, a rotating machine for rotating the first fan and the second fan in the same direction, a first heat exchanger having an upstream heat exchange part and a downstream heat exchange part, wherein; the upstream heat exchange part is located between the first fan and an outside air inlet so that air outside the vehicle flowed in from the outside air inlet is flowable through the upstream heat exchange part by the rotation of the first fan, the downstream heat exchange part is located between the first fan and a vehicle compartment outlet, so that the air outside the vehicle flowed in from the first fan is flowable through the downstream heat exchange part, the first heat exchanger is configured such that the flow of air outside the vehicle compartment flowing through the upstream heat exchange part and the flow of air outside the vehicle compartment flowing through the downstream heat exchange part are opposite flows, and a second heat exchanger is configured such that the air outside the vehicle compartment is flowable from the first fan through the downstream heat exchange part through the second heat exchanger, the first heat exchanger is an orthogonal heat exchanger configured to exchange heat as the inside air and outside air flow without being mixed and flow in cross, the second heat exchanger is a heat exchanger that is a component of a refrigeration cycle execution system, and the air conditioning unit is configured such that air in the vehicle compartment, which flows in from an inside air inlet by the rotation of the second fan and is discharged from an outlet to the outside of the vehicle, is flowable through the first heat exchanger exchanging heat with the air outside the vehicle compartment flowing through the first heat exchanger.
