Dual-Zone Vehicle Air Conditioning with Partitioned Heating and Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air conditioning systems in vehicles, particularly dual-zone systems, face challenges in accurately and independently controlling the temperature of each zone due to uneven air volume distribution and complex temperature air door based-air mixing structures.
Innovation Solution
The proposed air conditioning system includes a first and second refrigeration component, a first and second heating component, and corresponding control valves. These components are separated by a partition plate, allowing for independent control of each zone, reducing energy consumption, and facilitating miniaturization of the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a temperature air door based-air mixing structure is used to adjust dual temperature zone, then the air conditioning system can provide different temperatures for different zones, but the air volume distribution is uneven and control accuracy of each temperature zone is poor
Solution Approach 1:
The air conditioning system is divided into two independent temperature zones with separate control mechanisms. Each zone has its own air mixing structure and control valve, allowing independent temperature adjustment without interference from the other zone, thereby improving control accuracy while maintaining dual-zone capability
Solution Approach 2:
Different regions of the air conditioning system are given different local characteristics through separate air mixing structures for each zone. Each zone's air mixing structure is optimized for its specific temperature requirements, enabling precise local temperature control rather than uniform control across the entire system
2Device complexity
If a single-zone air conditioning system is used, then the system structure is simple, but it cannot meet personalized temperature requirements of different drivers and passengers
Solution Approach 1:
The single-zone system is segmented into multiple independent temperature zones, each with its own control mechanisms. This segmentation allows the system to provide personalized temperature control for different occupants while maintaining a relatively simple overall structure through modular design
Solution Approach 2:
The air conditioning system is designed with multi-functionality to serve multiple temperature zones simultaneously. Each zone can operate independently or in coordination, allowing the system to adapt to various usage scenarios and personalized requirements without requiring completely separate systems
3Volume of stationary object
If refrigeration and heating components are integrated without partition, then the system volume is reduced, but temperatures of different areas cannot be accurately controlled and energy consumption increases
Solution Approach 1:
The integrated refrigeration and heating components are segmented into separate functional areas using partition plates. This segmentation allows independent temperature control for each area, preventing energy waste from cooling and heating the same space simultaneously, while maintaining a compact overall system volume through the integrated layout
