• In spring and autumn, the sun will be much better. The effect will be much better. Solar products are environmentally friendly products, which are very useful for reducing greenhouse gas emissions. Reducing the air volume can increase the temperature, and increasing the air volume can increase the heating efficiency and dehumidification effect.
• More than 4,000 pieces per year of this collector are sold. The air temperature depends on the intensity and angle of the sun, as well as air volume. Please do not be misled by competitors!

• Heating

On a sunny day, the temperature of the injected air is approximately 5-30ºC higher than the outdoor or indoor air inlet temperature. In addition, the air temperature on the sunny side usually rises more than 10 °C under the big sun.

• Ventilation

Depending on the model, approx. 5 to 140 m³ dry, warm air is blown into the room per hour. The room can also be slightly ventilated on a cloudy day without sunlight. The fresh air of solar air heater squeezes the turbid air out of the room, keeping the air fresh and oxygen-rich. Avoid moisture, mold, fungus, formaldehyde (HCHO), TVOC, benzene and odor. The room air can be exchanged within 2 hours.

• Always give you a clean and healthy home

Improve the indoor environment, reduce the irritation caused by allergy, especially for newborns. Improvement on the dwelling atmosphere---- bring in oxygen and reduce carbon dioxide; discharge unpleasant odors which might cause allergies and discomfort; control the temperature and moisture of the room, prevent the emergence and spread of bacteria. When dry and warm air keeps flowing in the room, the damp, rot or mold would be long-term reduced. 

• Dehumidification and Humidification: Optimum level (for comfort as well as building quality) is a relative humidity (RF) of 40-70%.

Absorb room moisture and drain out the room. Ventilation + Heating = Dehumidification. Make sure the value of your holiday home and wooden furniture. Especially suitable for wooden houses and basements. Nakoair solar air heater in basement, can sufficiently solve the moisture in basement, and prolong the life span of indoor structure and electrical appliance. The problem: Humid basements. One of the first signs of humidity in the basement is the stale smell. The humidity will soon destroy items stored in the basement, such as textiles, cardboard boxes or furniture. In addition, the lack of regular ventilation will result in mould and harmful fungus. To make the rooms fit for use again they have to be heated, mechanically dehumidified and vented on a regular basis. Below 15 ºC, electric dehumidifier will frost, and dehumidification effect will be much worse. Moreover, dehumidifier needs refrigeration and consumes a lot of electricity. This usually results in high operating costs.

The dry climate indoor can easily cause virus and bacteria to multiply and spread. In addition, the dry air takes away water from the body, making them feel dry, feverish, depressed, coughing, hoarse, and sore throat.

• Reduce the amount of air pollution and greenhouse gases that result from the use of fossil fuels for heating.
• Safety: low voltage, no fire, no household electricity, no smoke or dust.

Function Introduction

Operation principle for OS20 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.
