Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners often fail to provide pleasant wind speeds, leading to discomfort due to direct cold air discharge, increased noise with high blower fan RPM, and require large panels or slow cooling rates without fans.
Innovation Solution
An air conditioner design featuring a rotatable discharge unit with multiple outlet ports of varying lengths and speeds, allowing for selective air discharge at different velocities to optimize user comfort and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the RPM of the blower fan is increased to maximize wind speed and airflow, then cooling efficiency is improved, but noise increases and user comfort deteriorates due to direct cold air discharge
Solution Approach 1:
The discharge unit is divided into multiple discharge ports with different characteristics: a first discharge port for high-speed airflow and a second discharge port for low-speed airflow. This segmentation allows the system to distribute airflow at different velocities, reducing direct cold air discharge to users while maintaining overall cooling efficiency.
Solution Approach 2:
The discharge unit is designed to be rotatable, allowing dynamic adjustment of the discharge direction and selection between different discharge ports. This enables the system to adaptively change airflow patterns based on operational conditions, optimizing both cooling efficiency and user comfort.
2Speed
If the blower fan RPM is increased to achieve high wind speed, then airflow capability is improved, but noise increases
Solution Approach 1:
The discharge unit segments airflow into different velocity streams through multiple discharge ports. The first discharge port handles high-speed airflow for effective cooling, while the second discharge port releases lower-speed airflow that generates less noise, thereby reducing overall noise levels while maintaining cooling performance.
3Speed
If the heat exchanger is minimized and blower fan RPM is increased, then wind speed is maximized, but discharge temperature is lowered causing user discomfort
Solution Approach 1:
By dividing the discharge unit into multiple ports with different characteristics, the system can release air at different temperatures and speeds. The second discharge port is designed to discharge air at higher temperature and lower speed, preventing direct contact with users and improving comfort while the first port maintains effective cooling airflow.
