solar ventilation fans
Solar attic fans are a real lifesaver especially during extremely hot days. You see, your attic can quickly transform into an overhead furnace if you do not provide it with effective ventilation or cooling system. The sun’s heat can percolate in the attic and significantly raise the temperature in your home. Surely, you can always put up an air conditioning system up in the attic, but doing so will also drive your electricity costs and carbon footprints way up the scale. With this dilemma in mind, the best solution is a solar-powered fan in your attic. This is especially true if your home is not fully insulated to begin with or if you want to prevent heat buildup in your home during the summer months.
Solar attic fans provide a more cost efficient alternative to conventional attic fans. A big number of American households have been using attic fans to protect their homes from too much heat. This type of fan has been proven effective in preventing hot air from being trapped in the attic. However, leaving fans on for hours on end can take its toll on your pockets. The ever increasing costs of energy can surely make you pull the plugs off ordinary attic fans. But with solar powered attic fans, you do not have to worry about your bills. Harnessing the sun’s energy will allow you to enjoy the functionality of conventional fans without causing your utility costs to go overboard. As a matter of fact, your attic cooling system will be for free if you use this type of attic fans.
When you use solar attic fans, your energy cost savings do not stop in the attic. Â Rather, the total air conditioning requirements for your entire home will go down as a result of having a cooler attic. Your air conditioners will not be working too hard and you can even afford to turn them off for a few hours during the day without significantly raising the temperature in the lower areas of your home. When you invest in a solar powered attic fan, you make a one-time payment and then fully amortize the total cost in as early as two summer seasons. After paying off the cost, you get to enjoy a cooler and more comfortable home for the whole year and totally for free. Now, it is like having an unlimited return on your investment.
But if you think that solar attic fans are only good during the hot days of summer, think again. These devices can actually help you preserve your home. During the winter months, moisture easily builds up in the attic. As you know, moisture can cause all sorts of problems in your home, from causing the deterioration of the wooden parts of your home to hastening discoloration on your walls. By using solar powered attic fan even during winter, you ensure that the air inside your home is dry, preventing moisture to develop.
Solar attic fans are all about efficient air circulation inside your home. By enhancing ventilation, you get a more comfortable living space the whole year round.

Fans, Ventilation And Heating $28.7 CONTENTS Centrifugal and Disk Fans – - – - . – 3 Heaters for Hot Blast and Ventilation – 25 Heating and Ventilating Machine Shops – - 39 Copjrigbt, 1010, The Industrlal Press, Publishers of Nrcn xxar, 49-55 LaLayette Street, Sew Tork City CHAPTER I CENTRIFUGAL AND DISK FANS Tbere are ta-o types of fans in common use, known as the centrifugal fan or blower, and the disk fan or propelier. The former consists of a number of straight or slightly curved blades extending radIalIy from an axis as shown in Fig. 1. When the fan is in motion, the air in contact with the blades is thrown outward by the action of centrifugal force and delivered at the outer circumference or periphery of the wheel. A gartial vacuum is thus produced at the center of the wheel, and air from the outside flows in to take the place of that which has been discharged. Ffg. 3 illustrates the action of a centrifu gal fan, the arrows showing the path of the air. This type of fan is usually enclosed in a steel plate casing of such form as to provide Fig. 1. Centnfvffal Fan Flg. 2. Cestrlmgal Fan n C d a s h for the free movement of the air as it escapes from the periphery of the wheel. An opening in the circumference of the casing serves as , an outlet into the distributing ducts which carry the air to the various rooms to be ventilated, or to the furnaces in the case of mechanical draft. h fan with casing is shown in Fig. 2. The discharge opening can be placed in any position desired, either up, down, top horizontal, bottom horizontal, or at any angIe. Where the height of the fan room is limited, a form called the threequarter housing may be used, in which the I o e r p art of the casing is replaced by a brick pit below MICHISEBT, October, Sorcrnber and December, 1903. the floor level see Fig. 4. Another form of the centrifugal fail is shown in Fig 6. This is known as the cone fan and Is commonly placed in an opening in a brick wall and discharges alr from its entire periphery into a room called a plenum@³33333ÿ¾Úð |

The Principles And Practice Of Colliery Ventilation $21.88 Purchase of this book includes free trial access to www.million-books.com where you can read more than a million books for free. This is an OCR edition with typos. Excerpt from book: ever must the regulators be placed in the intake currents, or Downcast Shaft as the air being drawn out of the pit at a greater speed than it enters it, a depression will be caused that may produce a blower of gas. A duplicate engine must be attached ready for use in case of a breakdown, and the engine must be properly governed to run steadily at any speed. Care must also be taken to construct a drift to the fan from the Upcast Shaft, so that in the event of an explosion, the fan itself and its gear may not be damaged. There are so many forms of Centrifugal Ventilators and Vacuum Fans, that a description of all would be impossible; the following Chapter will give the rules (expressed arithmetically) to find the cubic feet of air per minute required to ventilate the pit, and the fan must be guaranteed by the manufacturer to yield this result with a fair margin, in case of emergency. Phosphor bronze bearings in the fan itself will be found an economy, and great attention should be paid to the trimming of the oil cups, the firing of the engine, and the air doors in the pit, or the fan is no economy over the furnace. In designing Centrifugal Fans, the following rules may be observed for proportions. D = diameter of Fan, V = velocity in feet per second of the tips of the Fan blades. P ? pressure in Ibs. per square inch. V = /p x 97300 IT P = 97300 Length of Vane = ? Diamater of Centre = ? Width = ? Eccentricity of Fan = ? 4 ‘ 10 CHAPTER III. The Laws Of Chemical Combination As Applied To Combustion. In calculating the velocity and quantity of the air current, the first thing we shall require to know is the rule for ascertaining the quantity of air required for the complete combustion of the principal form of fuel; and it will be noted that the met… |

Solar Radiation and Daylight Models $85.44 The cost of operating a building far exceeds the cost of constructing it, and yet until recently little attention was paid to the impact of solar radiation on the costs of heating, cooling and ventilation. And now that there has been a surge in interest in energy efficiency and solar design, architects and designers need a practical guide to the modelling and application of solar energy data. There are many different models and techniques available for calculating the distribution of solar radiation on and in buildings, and these algorithms vary considerably in scope, accuracy and complexity. This book demonstrates which of these predictive tools gives the best results in different circumstances, including explaining which models can be best used in different parts of the world. The author has had over twenty-five years of experience of dealing with solar energy data from four continents and has used that experience in this book to show the development not just of knowledge but also the growing sophistication of the models available to apply it. *Based on many years of first-hand experience with solar data*Different models demonstrated and evaluated*Calculations that can be used anywhere in the world |
