Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If air intake area is increased by adding air inlet hole in bottom wall, then cooling capacity is improved, but device complexity increases
Solution Approach 1:
The patent introduces a new spatial dimension for air intake by adding an air inlet hole in the bottom wall of the indoor part, perpendicular to the traditional side-wall air intake direction. This multi-directional air intake approach increases the effective air intake area without requiring significant increases in chassis overall dimensions, thereby improving cooling capacity while maintaining relatively simple device structure.
Solution Approach 2:
The chassis is divided into distinct functional regions: indoor part with air inlet hole, outdoor part with condenser, and intermediate partition. This segmentation allows independent optimization of each region's function, enabling the bottom wall air inlet to be specifically designed for increased air intake area without affecting other structural integrity requirements.
2Power
If supercooling tube with bent segment is added to enhance heat exchange, then cooling performance is improved, but device complexity increases
Solution Approach 1:
The supercooling tube is designed with a bent segment that curves toward the indoor part, increasing the tube's contact length with condensate water. This curved configuration maximizes the heat exchange surface area within the limited space of the water storage tank, enhancing supercooling effect and cooling performance without requiring additional tube components or complex routing.
Solution Approach 2:
The supercooling tube is nested within the water storage tank, utilizing the existing tank space for dual purposes: water storage and heat exchange. The bent segment of the tube is positioned to optimally contact the condensate water inside the tank, creating an efficient heat exchange arrangement without occupying additional external space or requiring separate heat exchange components.
3Power
If water storage tank is added for refrigerant cooling, then heat exchange efficiency is improved, but device complexity increases
Solution Approach 1:
The water storage tank serves multiple functions simultaneously: it stores condensate water collected from the evaporator, provides a heat exchange medium for supercooling the refrigerant, and acts as a structural component of the chassis assembly. This multi-functionality approach improves heat exchange efficiency without requiring separate dedicated components for each function, thereby limiting the increase in device complexity.
Solution Approach 2:
The system utilizes the condensate water naturally collected during the air conditioning operation to provide the cooling function for the refrigerant. The evaporator produces condensate water that automatically flows into the water storage tank, which then serves as the cooling medium for the supercooling tube. This self-service approach eliminates the need for external cooling systems or additional water supply mechanisms.
