Integrated Air Duct Layout for Stable Indoor Ventilation Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The introduction of outdoor air into indoor environments through traditional air duct systems often causes drastic temperature changes due to significant differences between input and indoor air temperatures.
Innovation Solution
An air duct device comprising a heat-exchange air duct and a ventilation duct, where the air input channel of the ventilation duct passes by the air outlet of the heat-exchange duct, allowing for heat exchange and preheating or precooling of outdoor air, which is then circulated back into the heat-exchange duct for further purification and temperature regulation, minimizing temperature fluctuations within the indoor environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If outdoor air is introduced through traditional air duct systems, then ventilation and air purification are achieved, but drastic temperature changes occur in the indoor environment
Solution Approach 1:
The patent applies preliminary action by preheating or precooling the outdoor air in the air input channel before it enters the indoor environment through the ventilation duct. This preliminary temperature adjustment prevents drastic temperature changes in the indoor environment while maintaining effective air purification.
Solution Approach 2:
The patent uses the air input channel as an intermediary between the outdoor air source and the indoor environment. This intermediary channel performs heat exchange with the air outlet, serving as a buffer that mediates the temperature difference between outdoor and indoor air, thereby stabilizing indoor temperature while enabling ventilation.
2Ease of manufacture
If heat-exchange and ventilation ducts are arranged individually, then air purification function is achieved, but device size and cost increase
Solution Approach 1:
The patent merges the heat-exchange duct and ventilation duct into a single integrated device housing. The air input channel and ventilation duct are arranged within the same housing structure, combining multiple functions (heat exchange, ventilation, purification) into one compact unit, thereby reducing device complexity and manufacturing cost.
Solution Approach 2:
The air input channel serves multiple functions: it acts as both a heat-exchange passage and a ventilation duct. By making this component multi-functional, the patent eliminates the need for separate heat-exchange and ventilation duct systems, simplifying the overall structure and reducing manufacturing costs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively reduces temperature differences between outdoor and indoor air, preventing drastic temperature changes and improving indoor air purification efficiency while also achieving miniaturization and cost savings by integrating the heat-exchange and ventilation ducts within a single housing.
Implementation Method 1
the air input channel of the second air duct passes by the air outlet of the first air duct, and thus the air input channel of the second air duct passing by the air outlet of the first air duct also has the heat exchanges during the heat exchange of the first air duct
Implementation Method 2
The air outlet of the second air duct is communicated with the air inlet of the first air duct, and thus the air preheated or precooled by the air outlet of the first air duct enters the air inlet of the first air duct after being purified
