Analysis of the Necessity and Advantages of Bottom Vents in Atomizing Fireplaces

Necessity

1. Enhanced Air Circulation Atomizing fireplaces require adequate air supply to maintain optimal flame effects. Calculations show that approximately 11-13m³/h of airflow is needed per kilowatt of power. The bottom vent should maintain a minimum area of 150cm² to ensure sufficient air supply. The recommended distance between the vent and the floor is 15-20cm, effectively introducing cool air and promoting overall air circulation. Proper ventilation design can stabilize flame height at 25-30cm.

2. Prevention of Overheating Atomizing fireplaces generate heat of approximately 40-50°C during operation. Bottom vents working in conjunction with top exhaust create natural convection cooling. Proper vent placement (symmetrical front and back, evenly distributed left and right) maintains equipment internal temperature within safe limits (not exceeding 60°C), significantly extending equipment lifespan. It is recommended to use aluminum alloy materials for vent grilles due to their excellent thermal conductivity and durability.

Advantages

1. Improved Flame Effect Fresh air introduction through bottom vents of 150-200cm² helps maintain ideal flame heights of 25-30cm. Proper ventilation design allows atomized particles (diameter approximately 15-25 microns) to rise uniformly, creating more realistic flame effects. A 45-degree angle design for vents is recommended to further optimize airflow direction.

2. Safety Assurance Standards require indoor air exchange rates of no less than 3-4 times per hour. Bottom vents combined with 300m³/h exhaust capacity ensure indoor air quality. Additionally, bottom vents should incorporate protective mesh (aperture ≤4mm) to prevent foreign object entry. Testing shows this design maintains indoor CO₂ levels below the safe threshold of 1000ppm.

3. Aesthetic Appeal Vents can be finished with brushed aluminum alloy, complemented by LED strip lighting (3000K warm white, color rendering index Ra>90). The 45-degree angle design ensures both ventilation effectiveness and elegant appearance. Proper ventilation design coupled with 3D simulated flame technology can achieve over 95% realistic flame reproduction.

Conclusion Bottom vents are essential components of atomizing fireplaces. Proper design not only ensures safe and stable equipment operation but also enhances overall aesthetic appeal and user experience. It is recommended to strictly follow dimensional and positioning requirements during installation and select quality materials to ensure optimal performance.
