Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning systems face challenges in maintaining interior air quality due to malodors caused by fungal and bacterial metabolites, with unclear types and amounts of compounds contributing to these odors, necessitating a method to identify and address the specific compounds responsible for offensive smells.
Innovation Solution
A method for detecting and analyzing malodor compounds from air conditioners, involving gas collection and component analysis using techniques like GC/MS, GC/AED, and HPLC, followed by reproduction of the malodor composition using identified compounds such as ammonia, acetaldehyde, and other specific chemicals, and preparation of a corresponding malodor composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fungal and bacterial metabolites are present in air conditioner systems, then malodor is generated, but the specific types and amounts of compounds contributing to the odor remain unclear
Solution Approach 1:
The patent segments the complex malodor analysis into distinct compound categories (aldehydes, ketones, alcohols, organic acids, sulfur compounds, aromatic hydrocarbons) and uses targeted detection methods for each category, making the overall analysis manageable and precise
Solution Approach 2:
The patent employs GC/MS, GC/AED, and HPLC as intermediary analytical tools that convert the complex malodor mixture into identifiable individual compounds, enabling precise measurement of specific odor-causing substances
2Temperature
If air conditioning systems focus on temperature control, then cooling function is improved, but interior air quality and odor problems worsen
Solution Approach 1:
The patent converts the harmful malodor problem into beneficial information by identifying specific compound profiles, which can then be used to develop targeted odor removal strategies and improve overall air quality
Solution Approach 2:
The patent establishes a feedback mechanism by detecting and quantifying odor compounds in air conditioner systems, providing data that enables continuous improvement of air quality through targeted interventions
3Adaptability or versatility
If multiple offensive odor types are emitted from air conditioners, then odor variety increases, but understanding the fundamental cause becomes more difficult
Solution Approach 1:
The patent changes the detection parameters by using multiple analytical methods (GC/MS, GC/AED, HPLC) with different detection capabilities, allowing comprehensive identification of various odor compounds despite their diversity
