Size determining method and device for fresh air inlet, and indoor unit of air conditioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no simple and feasible method to determine the size of the fresh air inlet for air conditioners, leading to reduced heat exchange efficiency when attempting to introduce fresh air into indoor units, resulting in uncomfortable indoor environments due to moisture loss during the heat exchange process.
Innovation Solution
A method and device for determining the size of the fresh air inlet by calculating the cross-sectional area and diameter based on the outputting air volume and fresh air coefficient of the indoor unit, allowing for the optimal addition of fresh air inlets without compromising heat exchange efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fresh air inlet is added to the indoor unit of air conditioner, then indoor comfort is improved, but heat exchange efficiency is reduced
Solution Approach 1:
The patent applies parameter changes by establishing a mathematical relationship between the fresh air inlet cross-sectional area and the air outlet cross-sectional area using the formula S1/K ≤ S ≤ S1, where K is the fresh air coefficient and S1 is the air outlet cross-sectional area. This quantitative parameter specification allows the fresh air inlet size to be precisely controlled to maintain heat exchange efficiency while providing adequate fresh air supply for indoor comfort.
2Quantity of substance
If fresh air inlet size is increased, then fresh air supply is improved, but determination method complexity increases
Solution Approach 1:
The patent applies self-service by enabling the system to automatically determine the appropriate fresh air inlet size through calculation based on the air outlet cross-sectional area and fresh air coefficient, rather than requiring complex manual measurement and determination processes. The control unit automatically computes the optimal fresh air inlet area using the established mathematical relationship, simplifying the overall determination process.
3Ease of operation
If fresh air inlet is added without size determination method, then fresh air can be introduced, but heat exchange efficiency is inevitably reduced
Solution Approach 1:
The patent applies preliminary action by pre-establishing the mathematical relationship and determination method for fresh air inlet size before the actual installation and operation. The control unit is programmed with the fresh air coefficient K and the calculation formula, enabling it to automatically determine the optimal fresh air inlet cross-sectional area based on the air outlet dimensions, thereby preventing heat exchange efficiency reduction from the outset.
