Operation principle for OS20/30

The heated fresh air is blow into the house by a fan, driven by photovoltaic panel. The sun shines on the special heating absorption board and the surrounding air absorbs heat. The fan makes air transport which results in a contribution to heat the building and thus a saving on heating bills. Regular ventilation without power consumption. Nakoair air heater starts and stops according to the intensity of sunlight, and run without any maintenance. Reducing the air volume can increase the air temperature into the room. Increasing the air volume can increase the heating efficiency, the overall heat of the room.

Applications

Holiday Homes; Residential; Commercial Buildings; Cellar; Lofts; Garages; Workshop; Granges; Cabins; Summer Houses; Storage Rooms; Chalets; Sheds; Cottages; Caravans; Tents; Greenhouses; Drying Rooms; Gyms; Shops; Houses without electricity. Nakoair can be used to dry crops such as vegetables, fruits and grains.

Note that by setting up two panels, e.g. one facing east-southeast and one south-southwest, you can take full advantage of the available sunshine throughout the day.

 Parameter

• OS20/30

Just heating outdoor fresh air

• OS22/32/42

1. Heating outdoor fresh air;
2. Heating indoor air internal circularly.

Houses with little sunlight or poor insulation; rooms with frequent occupancy or high humidity require much larger models. For frequently occupied rooms, it is better to purchase OS22/32/42 with LCD thermostat and automatic vents.

 Product information

Mechanical thermostat

Standard configuration：Ventilator will stop working when the heated temperature reaches the set value (eg. 25℃ ).

Runs completely independent of the grid.

Fan brand: Sunon

Instead of hydraulic fan, double ball fan is adopted, with longer lifespan ( 70000h ), low temperature resistant.

The expected service life of photovoltaic panels is 15-20 years.

Easy installation & repair

Installing your solar panel is so easy that you can do it yourself without the help of electrician, construction worker. Small area, light weight. Product includes thermostat and all the necessary accessories for installation, such as screws, fixing clips, air ducts, air outlets, manuals, etc.

The 135mm hole saw for wooden walls or lightweight bricks already contains.

You can substitute the spare parts except pv panels all by yourself within 30 minutes, with easy tools like scissors, tape, screwdriver.

Frame and Sealing strips

The sealing strip is made of high-quality silicone rubber, which is sun-proof, weather-resistant and has a better appearance.

Frame: for open air, sun-proof texture coating, sun-proof outdoor screws.

Low iron solar tempered glass

Low iron solar tempered glass is with big intensity, high elasticity, the transmission is excellent:up to 92%. Lower diffuse reflection can prevent heat loss.

Adjustable Air Vent

Galvanized steel sheet, high temperature baking varnish, made with ingenuity. Strong, durable, anti-corrosion, fire prevention, rust-proof and sun-proof and do not change color.

New design: easy operation and installation. The air door can move 6mm in one circle, fast in and out. It is easy to open and close. An ordinary screw can only move 1 mm after one turn. It takes a long time to open or close the air door. Easy to install: Insert it first, then rotate, and it can be installed in 2 seconds. No need to tighten screws. The hose does not need to be fixed with a hoop.

Activated carbon filter: filter dust, drive off odor, silencer, prevent flying insects. Plug it in the air intake duct to the fan. It needs to be removed and cleaned in time to avoid blocking the warm air. Otherwise please do not use.

Fresh air inlet of solar air heater standard PET film: stops cold air, moisture, condensation of air humidity, and back draft( When the collector is not working).

Long life

Glass is much longer than polycarbonate panels, which are only 10 years. and after sunlight irradiation, polycarbonate panel becomes yellow and solar transmittance goes lower.
