AI Technical Summary

Technical Problem

Existing vehicle air conditioning systems cannot efficiently regenerate the adsorbent material of the humidification equipment while the battery is charging, which may require regeneration during the ride and affect the riding experience.

Method used

When the vehicle is connected to an external power source and there are passengers, the regeneration mode is implemented through the control unit. The external power is used to heat the adsorbent material, and the heating mechanism, which combines the honeycomb structure and PTC characteristic material, achieves efficient regeneration of the adsorbent material.

Benefits of technology

It enables efficient regeneration of adsorbent materials under external power supply, reducing the need for regeneration during passenger travel and improving the efficiency of humidity control inside the vehicle.

Abstract

The present application provides a vehicle air conditioning system capable of regenerating the adsorption material of a humidifying device more efficiently while using the power of an external power source. The vehicle air conditioning system (1) includes a humidifying device (2) having an adsorption section (20) and a heating mechanism (21), a passage (3) having a first flow path (31) and a second flow path (32), a valve (4), a blower (5), and a control section (6) that controls the humidifying device, the valve, and the blower. The control mode of the control section includes an adsorption mode in which the heating mechanism is not activated and the blower is activated to cause air (10) to flow into the first flow path (31), and a regeneration mode in which the blower and the heating mechanism are activated to cause air to flow into the second flow path (32). The control section (6) implements the regeneration mode when the following (1) and (2) are satisfied. (1) An external power source is connected to the vehicle; and (2) a radio wave from an electronic key held by a user of the vehicle is received or there is an occupant in the vehicle cabin.
