Vehicle Individual Air Conditioning with Temperature Control Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Eco-friendly vehicles face challenges in reducing energy consumption and preventing dew condensation on vehicle windows during individual air conditioning, particularly when only the driver is present, as existing systems often fail to efficiently control air distribution and humidity levels for both driver and passenger seats.
Innovation Solution
An individual air conditioning apparatus for vehicles, comprising driver's and passenger seat modules with evaporation and heater cores, temperature control doors, and a door controller that can close channels to direct air-conditioned air specifically to either seat, and an air guide to enhance DEF outlet airflow, allowing for efficient temperature control and humidity management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If individual air conditioning is performed by distributing air volume to driver's seat and passenger seat, then energy consumption is reduced, but dew condensation occurs on the window
Solution Approach 1:
The air conditioning system is divided into separate driver's seat and passenger seat modules, each with independent air conditioning ducts, evaporation cores, and heater cores. This segmentation allows individual air conditioning for each seat, reducing overall energy consumption while maintaining the ability to control air distribution to prevent dew condensation on windows
Solution Approach 2:
Temperature control doors are provided that can dynamically open or close channels to regulate air flow distribution. The door controller adjusts the position of these doors based on operating conditions, enabling the system to switch between individual air conditioning mode and modes that prioritize dew condensation prevention, thus resolving the contradiction between energy savings and window condensation
2Adaptability or versatility
If air conditioning ducts are provided for both driver's seat and passenger seat, then individual air conditioning is enabled, but device complexity increases
Solution Approach 1:
The system uses separate air conditioning modules for driver and passenger seats, each with its own duct, evaporation core, and heater core. This segmentation enables independent temperature control for each seat, providing adaptability for individual air conditioning needs
Solution Approach 2:
The temperature control doors serve multiple functions: they can close channels to direct air-conditioned air specifically to either the driver's seat or passenger seat for individual air conditioning, or open channels to allow air distribution that prevents dew condensation on windows. This multi-functionality reduces the need for additional dedicated components

AI summary
An individual air conditioning apparatus for a vehicle includes: a driver's seat air conditioning module and a passenger seat air conditioning module sequentially provided with an evaporation core and a heater core; a first channel that passes through the evaporation core and is connected to an indoor outlet; a second channel that passes through the evaporation core and the heater core and is connected to the indoor outlet; and a temperature control door that opens and closes the first channel and the second channel.
