Solution Overview
Problem
Conventional air conditioners often result in unpleasant temperature sensations for users due to high wind velocity and noise, and radiation-based systems are inefficient and costly.
Innovation Solution
An air conditioner design featuring a door unit with a movable door blade and controller to control air discharge direction and velocity, allowing for straight-line or radial discharge of heat-exchanged air through multiple dischargers, optimizing air distribution and user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rpm of the blower fan is increased to achieve high wind velocity, then air volume and cooling efficiency are improved, but noise increases and user comfort deteriorates
Solution Approach 1:
The patent divides the air discharge function into two separate discharge paths: a first discharger for high-velocity direct cooling and a second discharger for low-velocity radial air distribution. This segmentation allows the system to provide both efficient cooling and comfortable air distribution without the harmful effects of high noise levels.
Solution Approach 2:
The patent employs a movable door blade that can dynamically adjust its position to control the discharge mode. By moving the door blade to different positions, the system can switch between direct high-velocity discharge through the first discharger and radial low-velocity discharge through the second discharger, adapting to different operational requirements.
2Object-affected harmful factors
If a radiation-based air conditioning system is used instead of a blower fan, then noise is reduced, but panel size increases and cooling speed decreases
Solution Approach 1:
The patent merges the advantages of both blower fan-based systems and radiation-based systems by combining a blower fan with two types of discharge mechanisms. The first discharger provides blower-based high-speed cooling when needed, while the second discharger provides radiation-based low-noise air distribution, achieving both fast cooling and noise reduction.
3Temperature
If the heat exchanger is minimized in size and air velocity is maximized, then discharge temperature is reduced, but user comfort deteriorates due to direct exposure to high-velocity cold air
Solution Approach 1:
The patent applies different discharge qualities to different users and locations. The first discharger provides high-velocity cold air for areas requiring rapid cooling, while the second discharger provides low-velocity radially distributed air for areas where user comfort is the priority. The movable door blade enables selective activation of each discharge mode based on local requirements.
