The heat recovery full-displacement fresh air system ensures 24-hour fresh air supply indoors, achieving an air exchange rate of 0.5-0.8 times/hour per room, and approximately 300 m³/hour per household. Return (exhaust) air is centrally exhausted from the bathroom, undergoing heat recovery by the rooftop fresh air handling unit. This unit features a high-efficiency plate-type full heat recovery unit, ensuring no cross-contamination between supply and exhaust air, with a heat recovery rate exceeding 60%.
The fresh air system replaces indoor air polluted by living conditions with fresh outdoor air, maintaining indoor air cleanliness at a minimum standard. Furthermore, fresh air systems are used in environmental remediation projects, such as suppressing odor emissions through air injection and extraction systems, combined with deodorizers for comprehensive dust and odor removal. In addition to maintaining fresh indoor air, the fresh air system is energy-efficient and also offers additional functions such as temperature and humidity control, and disinfection, making it suitable for various indoor spaces.
