In the application, since 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, a second heat exchanger through which the air outside the vehicle compartment flowing from the first fan through the downstream heat exchange part flows, a first heat exchanger is an orthogonal heat exchanger, the second heat exchanger that is a component of a refrigeration cycle execution system, the air in the vehicle compartment, which flows in from the inside air inlet by the rotation of the second fan and is discharged from the outlet outside the vehicle through the first heat exchanger, and the air outside the vehicle compartment, are exchanged with the first heat exchanger, it can be miniaturized along with the improvement of electricity cost.

Provided is an air-conditioning system including: an air pollution level detector configured to detect each of a pollution level of outside air, which is air outside a vehicle, and a pollution level of inside air, which is air inside the vehicle; and an air-conditioning control device configured to control air conditioning by switching an air-conditioning mode of the vehicle between an inside-air circulation mode and an outside-air introduction mode. The air-conditioning control device switches the air-conditioning mode from the outside-air introduction mode to the inside-air circulation mode based on the pollution level of the outside air acquired from the air pollution level detector, and switches the air-conditioning mode from the inside-air circulation mode to the outside-air introduction mode based on the pollution level of the inside air acquired from the air pollution level detector.

A recreational vehicle air conditioning system supports multiple recreational vehicle air conditioning units having closed air conditioning circuits and a controller that is electronically coupled to each of the recreational vehicle air conditioning units to control each of the closed air conditioning circuits to regulate an overall power consumption of the multiple recreational vehicle air conditioning units.
