1. Unique feature: Indoor air internal circulation mode: heating indoor air internal circularly. Applicable to OS22/32/42.
Heating indoor air mode, can keep heating the room air, and keeps away from any wet or cold or smog air. When people at home or when in the winter morning, just open the room air inlet; when people out or at noon, close the room air inlet and introduce fresh air to ventilate and dehumidify.
2. Special heating absorption board:
Corrugated special anodic aluminum oxide, texture nano heat insulation coating, high absorption, low reflection. Solar absorbance of selective absorbing coating: 0.92; Hemisphere emittance of selective absorbing coating: 0.12.
3. Solar photovoltaic panels are produced with well-known brand cell in high quality, high photoelectric conversion efficiency, low conversion efficiency attenuation rate, with life expectancy for 20 years. Collectors can be used to dry crops such as vegetables, fruits and grains. The service life of photovoltaic panels will not be affected even under high temperature and strong light in tropical and subtropical regions.
4. Instead of hydraulic fan, double ball fan is adopted, with longer lifespan, low temperature resistant. SUNON from Taiwan is the most well-known fan brand in the world.
5. Under sunlight, the air inside the Nakoair® air collector flows along both sides of the heat absorbing plate and can absorb the heat well from the absorbing plate.
6. Air vent: it is possible to be opened and closed automatically, with 8mm thermal insulation cotton inside, good insulation effect. Automatically turns off when the fan is not running.
7. Sealing strips are with high-quality silicone rubber: anti-UV, climate-resistance, better appearance. Frame: exclusively for open air, anti-UV texture coating, anti-UV outdoor screws.
8. Low iron solar tempered glass is with big intensity, high elasticity, the transmission is excellent. Lower diffuse reflection can prevent heat loss.
Glass is much longer than polycarbonate panels, which are only 10 years, and after sunlight irradiation, it becomes yellow and solar transmittance goes extremely lower.
9. Fresh air inlet of solar air heater standard PET film: stops cold air, moisture, condensation of air humidity, and back draft (when not working).
