離子驅動無葉式全熱交換機 Ion-Driven Bladeless Total Heat Exchanger
This study developed an ion-driven bladeless total heat exchanger to address indoor air quality issues caused by excessive carbon dioxide concentration in enclosed spaces. The system replaces traditional fans with ionic wind technology as the airflow source, offering features such as low noise, low power consumption, and maintenance-free operation. Combined with total heat exchange technology, it simultaneously recovers indoor thermal energy during ventilation to reduce air conditioning energy consumption. The device can be installed on windows or walls and uses a CO₂ sensor to continuously monitor air quality; when the concentration exceeds a preset threshold, the ventilation function is automatically activated. To prevent ozone produced during ion generation from affecting human health, the airflow passes through a manganese dioxide catalytic layer that converts ozone into oxygen, ensuring safe exhaust. Experimental results show that the ionic wind generator can reach a maximum air velocity of 1.5 m/s within the effective range of 1–2 m/s, and in a 10 m³ enclosed space, it can reduce CO₂ concentration from 720 ppm to 540 ppm within 30 minutes, a 30.5% decrease. This study verifies the feasibility of applying ionic wind technology to total heat exchange systems, demonstrating advantages in energy efficiency, low noise, and intelligent control.
