Vehicle Air Conditioning Unit Relocation to Engine Room
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle air conditioning systems installed inside the dash panel cause noise, vibration, and space constraints, leading to reduced passenger convenience and accessibility for maintenance.
Innovation Solution
The air conditioning unit with noise-inducing components is relocated to the engine room, and a distribution duct is placed inside the vehicle, minimizing noise and vibration while maximizing interior space and improving accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the air conditioning unit with noise-inducing components is installed inside the vehicle based on the dash panel, then the air conditioning system can be easily accessed for maintenance, but noise and vibration increase in the interior of the vehicle
Solution Approach 1:
The air conditioning system is divided into two separate parts: the air conditioning unit (containing noise-inducing components like compressor and condenser) is installed in the engine room, while the distribution duct (containing air outlets and control mechanisms) is installed in the interior based on the dash panel. This segmentation allows maintenance access to both parts while isolating noise sources from the passenger compartment.
2Ease of operation
If the air conditioning system is installed inside the vehicle, then air distribution can be optimized, but interior space is reduced and passenger convenience is deteriorated
Solution Approach 1:
The air conditioning unit is relocated from the interior space to the engine room, utilizing the three-dimensional space available in the engine compartment. This dimensional relocation allows the distribution duct to be positioned optimally in the interior for efficient air distribution, while the bulk of the system occupies space that would otherwise be unusable, thereby preserving passenger compartment volume.
3Object-affected harmful factors
If the air conditioning unit is arranged in the engine room, then noise and vibration are reduced in the interior, but accessibility for follow-up service may be reduced
Solution Approach 1:
The system is segmented into two serviceable components: the air conditioning unit in the engine room and the distribution duct in the interior. Both components are designed with accessible mounting positions and connection points, allowing technicians to service either part independently without requiring complete system disassembly or relocation.
4Ease of operation
If the air conditioning system occupies interior space, then air distribution is improved, but passenger convenience such as foot rest and storage is reduced
Solution Approach 1:
The air conditioning system is segmented into the engine room-mounted unit and the interior-mounted distribution duct. This segmentation minimizes the footprint within the passenger compartment, preserving space for passenger convenience features while maintaining effective air distribution through strategically positioned outlets in the distribution duct.

AI summary
Disclosed herein is an air conditioning system for a vehicle, in which an air conditioning unit having noise inducing unit is arranged at an engine room based on a dash panel and a distribution duct for distributing air to the interior of the vehicle is arranged in the interior of the vehicle based on the dash panel, thereby reducing noise and vibration in the interior of the vehicle, securing visibility and enabling a worker to easily access the air conditioning system for follow-up service because the air conditioning unit causing noise is arranged inside the engine room, and enhancing passengers' convenience by maximizing the interior space of the vehicle in comparison with the conventional air conditioning systems because only the distribution duct is arranged in the interior of the vehicle.
