Function of Nakoair® solar air heater

1. Heating

The built-in solar powered 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. On a sunny day, the temperature of the injected air is approximately 5-30°C 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.

2. Ventilation

The fresh air of solar air heater squeezes the turbid air out of the room, keeping the air fresh and oxygen-rich.  

Depending on the models, approx. 5 to 140m³/h dry, warm air is blown into the room. The room can also be slightly ventilated on a cloudy day without sunlight. Humid air is drove out of the room through a built-in valve or the cracks and crevices of the building.

Ventilation is a key factor to the state of every building. Stagnant indoor air increases the risk of fungi, rot and other unwanted consequences.  

Preserve the value of your vacation home while getting fresh air – for free and all year round!   

 

  3. Dehumidification or humidification

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

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. Electric dehumidifiers will frost below 15 °C, so the dehumidification effect will be worse. In addition, the dehumidifier requires refrigeration and consumes a large amount of power. 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.

4. Healthy and fresh indoor climate          

Improve the indoor environment, reduce the irritation caused by allergy and asthma, 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.

WHO (World Health Organization) lists indoor air pollution as one of the top 10 threats to human health. When indoor ventilation conditions are poor, gas pollutants will accumulate indoors, and the concentration will increase, causing serious indoor air pollution.

Ventilation, heating, dehumidification or humidification. Solar collector with LCD thermostat, provides you with a healthy and warm home and automatically processes indoor air. Simple operation, thoughtful air management expert!
When it's a sunny day, the collector will keep heating the room in the morning & afternoon. At noon, it will automatically heat fresh air outdoor to ventilate / dehumidify all room, supply you fresh air all day. This function is only applicable for OS22/32/42. Ventilation can be extended at noon in spring / autumn.
Even in rainy or cloudy weather, the collector will provide fresh air to you by automatically switching to electricity, and the power consumption is less than 10kWh per year. When the outdoor temperature reaches its highest level at noon in spring / autumn / winter, or when the weather is cool in the summer evenings, it will ventilate the room to improve the indoor temperature; keep you warm in winter and cool in summer. The collector can also dehumidify or humidify the room according to the difference of moisture content between indoor and outdoor to maintain a relative humidity of 40-70%. The dry air outside will automatically drive away the humid air indoor. Similarly, the humid outdoor air will automatically humidify the room.
