Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioner apparatuses without ventilation functions can only circulate indoor air, leading to deteriorated air quality when used for cooling or heating, and existing models that exchange outdoor and indoor air lack efficient heat exchange mechanisms.
Innovation Solution
An air conditioner apparatus with a dual-channel module system, including suction and discharge channels, heat exchangers, and dampers, allowing for efficient heat exchange with heat exchangers that cover the entire surface, enabling both circulation and ventilation modes while optimizing air flow and heat exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If air is circulated without outdoor air introduction, then energy consumption is reduced, but air quality deteriorates
Solution Approach 1:
The system dynamically switches between circulation mode (indoor air only) and ventilation mode (outdoor air introduction) based on operational needs, allowing the air handling configuration to adapt between energy-efficient and quality-maintaining states
Solution Approach 2:
The air conditioner is designed to perform multiple functions: both air circulation for energy efficiency and air ventilation for quality maintenance, unified in a single system that can operate in different modes
2Object-affected harmful factors
If outdoor air is introduced for ventilation, then air quality is maintained, but heat exchange efficiency decreases
Solution Approach 1:
The air handling system is segmented into separate channels: a first channel for outdoor air intake and a second channel for indoor air circulation, allowing independent optimization of each flow path for its specific function
Solution Approach 2:
A partition plate is introduced as an intermediary structure to separate and organize the different air flows, ensuring that outdoor and indoor air streams do not mix and can be processed independently through the heat exchanger
3Loss of energy
If heat exchanger surface area is increased, then heat exchange efficiency is improved, but device complexity increases
Solution Approach 1:
The partition plate extends in the vertical dimension to divide the heat exchanger into multiple sections, effectively increasing the heat exchange surface area utilization without requiring a larger horizontal footprint or more complex three-dimensional structures
