Indoor Air Gas Exchanger Control for Rapid Pollution Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Indoor air pollution poses a significant threat due to the presence of harmful gases such as PM1, PM2.5, PM10, carbon dioxide, TVOC, formaldehyde, and pathogens, which can endanger human health, and existing solutions lack effective real-time monitoring and rapid purification capabilities.
Innovation Solution
A portable gas detection device is used to monitor indoor air quality and remotely control a network of gas exchangers that purify the air by inhaling outdoor gas, filtering it, and reintroducing it into the indoor space, with adjustable airflow rates from 200 to 1600 CADR, ensuring pollutants are reduced to safe levels within minutes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a portable gas detection device is used to monitor indoor air quality in real time, then the ability to detect and respond to air pollution is improved, but the complexity of the monitoring system increases
Solution Approach 1:
The portable gas detection device is designed to detect multiple types of air pollutants simultaneously (PM2.5, PM10, CO, TVOC, formaldehyde, etc.), making it a multi-functional monitoring device that consolidates what would otherwise require multiple separate detectors, thereby improving measurement precision without proportionally increasing system complexity
Solution Approach 2:
The detection device serves as an intermediary that communicates with the gas exchanger system through wireless signals, enabling remote monitoring and control without requiring direct physical connection or complex integrated control systems, thus improving detection capability while keeping system complexity manageable
2Productivity
If multiple gas exchangers are deployed to rapidly purify indoor air, then the purification speed is improved, but the device complexity and cost increase
Solution Approach 1:
The air purification system is divided into multiple independent gas exchanger units distributed throughout the indoor space, each capable of operating autonomously. This segmentation allows the system to achieve high purification speed through parallel operation while keeping each individual unit relatively simple and manageable
Solution Approach 2:
The system dynamically adjusts the number and operation intensity of gas exchangers based on real-time air quality data from the detection device. When air quality deteriorates, more exchangers are activated or existing ones increase their airflow rate, enabling the system to achieve high purification speed only when necessary, thus balancing productivity with device complexity
3Productivity
If the gas exchanger operates at high airflow rate to quickly reduce pollutants, then the purification efficiency is improved, but the energy consumption increases
Solution Approach 1:
The gas exchanger dynamically adjusts its airflow rate based on real-time air quality conditions. When pollutant levels are high, the system operates at high airflow rates (up to 1600 CADR) to quickly reduce contaminants. When air quality improves or stabilizes, the airflow rate is reduced, thereby achieving high purification efficiency when needed while minimizing energy consumption during normal conditions
Solution Approach 2:
The system implements a feedback control mechanism where the portable gas detection device continuously monitors air quality and sends signals to adjust the gas exchanger's operation. This feedback loop ensures the system operates at high energy consumption levels only when necessary to achieve rapid pollutant reduction, rather than running at maximum capacity continuously, thus balancing purification efficiency with energy consumption
