Outer Circulation Layout to Prevent Air Conditioner Hot Air Re-Inhalation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners suffer from decreased heat dissipation efficiency due to the re-inhalation of hot air from the outer circulation unit, which reduces their effectiveness.
Innovation Solution
The air conditioner design features an outer circulation unit with an outer circulation inlet higher than the outlet in a vertical direction and blades tilting towards the ground, preventing hot air from being re-inhaled and enhancing heat dissipation efficiency by directing airflow away from the inlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the outer circulation inlet and outlet are positioned at the same height, then the structure is simple, but hot air is re-inhaled reducing heat dissipation efficiency
Solution Approach 1:
The patent applies dimensional change by positioning the outer circulation inlet and outlet at different vertical heights rather than the same level. The inlet is located at the upper portion while the outlet is at the lower portion, creating a vertical height difference that prevents hot air re-inhalation and improves heat dissipation efficiency without significantly increasing structural complexity.
2Loss of energy
If the outer circulation outlet is positioned higher than the inlet, then hot air may be blown away from the inlet, but the structure becomes more complex and may not effectively prevent re-inhalation
Solution Approach 1:
The patent inverts the conventional arrangement by positioning the inlet higher than the outlet, opposite to the typical configuration. This inverted positioning, combined with the tilting blades, effectively directs the exhaust airflow away from the inlet area, preventing hot air re-inhalation while maintaining structural simplicity.
3Productivity
If conventional inlet and outlet positioning is used, then the structure is simple, but heat dissipation efficiency decreases due to hot air re-inhalation
Solution Approach 1:
The patent applies asymmetry by creating an uneven vertical positioning between the inlet and outlet, with the inlet located higher than the outlet. This asymmetric arrangement, combined with the tilted blade configuration, creates an effective airflow pattern that directs exhaust away from the inlet, preventing hot air re-inhalation and improving heat dissipation efficiency.

AI summary
An air conditioner is provided that includes an outer circulation unit. The outer circulation unit includes an outer circulation housing, an outer circulation inlet, an outer circulation outlet, and a condenser. The outer circulation inlet is formed on the outer circulation housing. The outer circulation outlet is formed on the outer circulation housing. An outer circulation flow enters the outer circulation unit via the outer circulation inlet, passes through the condenser to remove heat from the condenser, and leaves the outer circulation unit via the outer circulation outlet, wherein the height of the outer circulation inlet is higher than the height of the outer circulation outlet in a vertical direction.
