How do formaldehyde and carbon dioxide sensors drive fresh air systems to intelligently monitor and automatically adjust air quality?
Publish Time: 2025-08-18
With modern living environments increasingly focused on health and energy efficiency, the two-way flow full-heat fresh air system, with its superior overall performance and forward-thinking technology integration, has become an indispensable "breathing center" for high-end residences, offices, and public buildings. It's no longer just a simple air replacement device; it's a comprehensive air management solution incorporating intelligent sensing, efficient purification, energy recovery, and silent operation. With a high air volume of 600 m³/h, 97% purification efficiency, a noise level as low as 38 dB, and 60% heat recovery efficiency as its core attributes, this fresh air system minimizes energy consumption while ensuring indoor air quality, redefining the standards of comfortable and sustainable living.
At first glance, the two-way flow full-heat fresh air unit's design exudes the sophistication of a high-end home appliance and the robustness of industrial equipment. Its EPS thermal insulation liner effectively isolates the unit from external temperature influences, preventing condensation and significantly improving its overall energy efficiency. The clean, sleek exterior, typically available in matte white or metallic gray, blends effortlessly into modern homes and commercial spaces. The control panel features an integrated high-definition display or can be remotely controlled via a mobile app, displaying key indoor parameters such as formaldehyde, CO2 concentration, temperature, and humidity in real time. The highly visual data allows users to monitor air quality at all times. The standard two DC inverter fans operate smoothly and efficiently, maintaining low noise levels even at maximum airflow. A sound pressure level of 38dB, comparable to a library, ensures no disturbing nighttime operation.
The core innovation lies in the synergistic mechanism of "two-way flow" and "full heat recovery." This two-way flow, full-heat fresh air system utilizes independent supply and exhaust ducts, achieving true two-way ventilation: fresh outdoor air is purified through primary and high-efficiency filters and then delivered indoors, while contaminated indoor air (containing high concentrations of CO2, odors, and VOCs) is simultaneously exhausted. The full-heat exchange core plays a key role in this process, leveraging the thermal conductivity and moisture permeability of the material to exchange temperature and humidity between the supply and exhaust air. In winter, the warm, moist exhaust air transfers heat and moisture to the cool, dry incoming air, preventing indoor heat loss. In summer, the cool exhaust air pre-cools and dehumidifies the fresh air, reducing the air conditioning load. A 60% heat recovery efficiency means nearly two-thirds of the energy is recycled, significantly reducing heating and cooling energy consumption, achieving a win-win for both the environment and the economy.
Another key feature is its intelligence. Equipped with built-in sensors for formaldehyde, carbon dioxide, and indoor and outdoor temperature, the two-way flow full heat fresh air system automatically senses changes in air quality. When formaldehyde levels exceed the standard or CO₂ concentrations are too high, it automatically increases air volume to accelerate ventilation. When there is a large difference in indoor and outdoor temperature, it optimizes heat recovery mode to balance comfort and energy savings. Some high-end models also integrate with smart home systems, autonomously adjusting the air quality throughout the home based on sleep patterns, weather forecasts, and occupant activity, truly achieving "invisible protection, intelligent breathing."
In terms of purification capabilities, the dual-layer primary and high-efficiency filtration system effectively intercepts particulate matter such as PM2.5, pollen, dust, and bacteria. Its 97% purification efficiency meets medical-grade standards, making it particularly suitable for people with allergies, children, and the elderly. A filter replacement reminder ensures the system is always in optimal working condition, preventing efficiency loss due to filter clogs.
The two-way flow full-heat fresh air system is a profound example of technology empowering healthy living. It uses silent airflow to weave a clean breathing network and intelligent algorithms to balance energy flow. With every breath of fresh air, it silently fulfills its commitment to a high-quality living environment—making freshness no longer a luxury and energy conservation a norm.
