An attic fan is useful when an attic has very low airflow and when there is a crack or space in the closing in between the attic and the remaining portion of the building. The fan enhances the airflow, pulling air up out of the building to the attic, reducing the dampness in the air and also saving power. The attic fan acts to cool down the entire building, not just the attic. The fan pull up the cold air to the attic when it enter the house from the windows. It's a good idea to use solar-powered fan for this reason. As solar fan doesn't have cords to plug in, it lessens the risk of electric incidents and fire, it's also environmentally friendly, and it's less costly in the end (although it may be slightly pricey in the beginning).
Solar fan can also be placed in greenhouse where it can assist in the air flow and humidity control. (Cooling isn't a concern in a greenhouse while it is within an attic). Location of the solar cells that control the fan is very important in this circumstance because it's not advisable to hinder the natural light entering the greenhouse itself. Plants need fresh air just as much as pets do, since plants breathe in their very own fashion, and a well-insulated greenhouse can lack appropriate circulation.
A smaller version of a solar fan is available for cars. The goal is not to cool down or ventilate the car while traveling (for that, air cooling performs a lot better, even if it's of the four-forty style -- leaving all four windows open while traveling 40 mph or perhaps faster), but rather for giving air flow plus some cooling while the automobile is parked unde
r the sun in a scorching climate. The fan matches the top of a window and is powered by a tiny solar cell. It recirculates air from outside to the car and scorching, stale air from the auto to the outside. This may make the auto more at ease after direct exposure to the hot sun, and also minimize the probability of dangerous chemicals being emitted by the car's upholstery in high-temperature situations.
You'll find solar fan kits which can be used in constructing ventilation that is 50% off the price of the whole fan. Amazon, eBay, and also other outlets for cheap purchases online have solar fan kits for only 10. The amount of work necessary to position the fan together is very little and basically requires linking the solar panel into the fan itself.
One can also find hats provided with built-in tiny solar fans for cooling the skull on scorching days. It is best for a jungle safari or simply revitalizing talk.
