Air Conditioner Multi-Discharge Design for Low-Noise Comfort Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners often cause discomfort due to high wind speeds and noise, and radiator types are inefficient and costly, with slow cooling and large construction requirements.
Innovation Solution
An air conditioner design featuring a housing with a heat exchanger, multiple discharge portions, and adjustable blowing fans to control air flow speed and direction, allowing for comfortable cooling and heating with minimal wind speed through selective discharge of heat-exchanged air via first and second discharge portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the RPM of the blowing fan is increased to maximize wind speed and air flow rate, then cooling performance is improved, but noise is increased and user comfort is reduced
Solution Approach 1:
The discharge portion is divided into multiple discharge holes instead of a single large opening, allowing air to be discharged through multiple smaller pathways. This segmentation reduces the wind speed at each discharge point while maintaining overall air flow rate, thereby reducing noise and improving user comfort without sacrificing cooling performance
Solution Approach 2:
Different regions of the discharge portion have different numbers and sizes of discharge holes, creating localized variations in air flow characteristics. This allows certain areas to provide higher velocity for effective cooling while other areas provide lower velocity for comfort, resolving the contradiction between cooling performance and user comfort
2Speed
If the blowing fan is used to achieve high wind speed, then cooling speed is improved, but device complexity and construction cost increase
Solution Approach 1:
The blowing fan component is removed from the system entirely. Instead of using mechanical force to drive air flow, the design relies on natural convection currents generated by temperature differences between the heat exchanger and surrounding air, achieving cooling without the complexity and cost of fan motors and control systems
Solution Approach 2:
The mechanical blowing fan system is replaced with a thermal convection-based system. The heat exchanger creates temperature gradients that drive natural air circulation, substituting mechanical energy input with thermal energy-driven fluid motion, thereby reducing device complexity and construction cost while maintaining cooling effectiveness
