An air conditioner with air purification function and the control method thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners with integrated air purification filters face issues such as increased airflow resistance, reduced heating/cooling efficiency, and shortened filter life due to filters being used even when pollution levels are below acceptable thresholds.
Innovation Solution
An air conditioner with sensors that detect pollution levels and a movement mechanism to automatically position additional filters on the air suction duct when needed, ensuring efficient airflow and extending filter life by only activating filters when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If additional filters are placed along the suction line to improve air purification, then air quality improvement capability is enhanced, but airflow resistance increases and heating/cooling efficiency decreases
Solution Approach 1:
The patent applies the dynamics principle by making the filter position adjustable rather than fixed. The filter can be moved between a retracted position (during heating/cooling operation) and an extended position (during air purification mode). This dynamic positioning allows the system to optimize airflow during heating/cooling while enabling effective filtration during purification mode, thus resolving the contradiction between air quality improvement and energy efficiency.
2Reliability
If filters are continuously exposed to airflow to maintain purification readiness, then air purification capability is maintained, but filter life decreases due to unnecessary exposure
Solution Approach 1:
The filter is designed with dynamic positioning capability, allowing it to be retracted when air purification is not needed and extended when purification mode is activated. This ensures the filter is only exposed to airflow when actually required for purification, maintaining purification readiness while significantly extending filter life by minimizing unnecessary exposure.
Solution Approach 2:
The system prepares for air purification by pre-positioning the filter in the extended state when pollution levels are detected or purification mode is selected. This preliminary action ensures the filter is ready for immediate operation without requiring continuous exposure, thus maintaining purification capability while conserving filter life.
