Solution Overview
Problem
Existing air-conditioning systems face challenges in integrating air purifiers with air conditioners due to differences in air discharge regions and the use of HEPA filters causing airflow resistance, and existing ceiling-mounted systems complicate filter replacement.
Innovation Solution
An integrated air-conditioning system with a first air-processing apparatus for temperature control and a second air-processing apparatus for air purification, featuring a filter cleaner that moves along guide rails for easy filter replacement and a louver system for adjustable air discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a HEPA filter is mounted in the air conditioner inlet region, then air purification efficiency is improved, but airflow resistance increases making it difficult to operate
Solution Approach 1:
The filter system is segmented into a pre-filter (first filter) and a HEPA filter (second filter) positioned in separate regions. The pre-filter is located in the inlet region to remove large particles, while the HEPA filter is positioned downstream to capture fine particles without creating excessive resistance at the inlet, thus resolving the contradiction between purification efficiency and airflow operation.
Solution Approach 2:
A pre-filter acts as an intermediary element between the inlet and the HEPA filter. It removes larger particles first, reducing the load on the HEPA filter and minimizing overall airflow resistance while maintaining high purification efficiency for fine particles.
2Ease of manufacture
If air conditioner and air purifier are physically separated at different positions, then each device can be optimized for its function, but the air discharge regions differ reducing overall efficiency
Solution Approach 1:
The air conditioner and air purifier functions are merged into a single integrated device. The system combines the heat exchanger (for temperature control) and the HEPA filter (for purification) within one unit, with a common outlet that discharges both conditioned and purified air to the same region, thereby improving overall air discharge efficiency while maintaining functional optimization.
3Area of stationary object
If ceiling-mounted structure is used for air processing apparatus, then space utilization is improved, but filter replacement becomes difficult due to ceiling inaccessibility
Solution Approach 1:
The filter assembly is designed with movable components that allow it to be lowered from the ceiling-mounted position during maintenance. The filter can be dynamically repositioned to an accessible location for easy replacement, then returned to its ceiling-mounted operational position, thus resolving the contradiction between space utilization and ease of repair.
