Using window fans to help cool your home can be a very efficient and economical way to provide comfort as well as helping the environment. When used properly, window fans can reduce energy costs and help draw the heat away from your home. Proper placement of window fans can make a big difference in how your living space feels. With just a few simple steps, you can use window fans to bring down the heat and make your home a more inviting place to relax and unwind.

How to Use Window Fans

Determine the type of weather you have outside to see if using window fans will work for you. If it is humid or hot during the evenings outside, they will not cool the house properly.

Decide how many window fans you want to use and where you would like to place them. You want to also have fans being used to draw the hot air out of the home, using about a 60/40 ratio with more air being drawn in than blown out.

Place intake fans in windows that are on the east side of the home near shady areas and exhaust fans on the west side of the home where the air is hotter in the afternoon. Always keep the intake fans on the opposite side of the home from the exhaust fans.

Attempt to place window fans in areas where they can take advantage of the outside wind direction if possible and check wind direction periodically, but always keep in mind to place the intake fans on the cooler sides of the home such as the eastern and northern sides. It doesn’t do any good to place the fans with the wind direction if you are blowing hot air into the home.

Keep fans blowing through the house in one direction for better cooling ability. Do not create a situation where the fans are blowing against each other.

Place fans inside the window frame and close the window down on the fan to keep the air circulating one way. If needed, use cardboard or wood to close the gaps in the sides of the window so the fans will continue to blow one way.

Run the fans during the coolest part of the day and in the evening for the best cooling effect. Close the window blinds or drapes during the heat of the day to keep the home cool.

Floor fans are dust magnets and the dust is often clearly visible on the fan blades. Not only is a dirty floor fan unsightly, the dust buildup can be irritating for people with allergies. It is necessary to clean floor fans periodically to remove this buildup from the fan blade and other parts of the fan. Washing floor fans regularly will not only keep the dust count lower in your home, but will also increase the lifespan of the floor fan. The easiest way to clean floor fans is by disassembling the fan so you can reach all of the parts.

Unplug the floor fan from the electrical outlet.

Use a Phillips screwdriver to remove the front grill from the back grill. Some fans will not have screws securing the front and back grills. Instead, use your fingers to pop off the clips holding the front grill to the back grill, and then lift up on the front grill to remove it from the base.

Turn the blade cap clockwise to unscrew it, and pull it off. The blade cap is situated right in the center of the fan blade. Slide off the fan blade from the back grill after removing the blade cap.

Remove the back grill nut from the back grill with your fingers or a wrench, depending on how tight the nut is secured into place. Slide off the back grill from the base of the fan.

Fill a bucket with warm water. Add a few drops of mild dish soap, and use your hands to mix up the soap and water.

Dip a rag into the soapy water and wring it out well. Wipe down each part of the fan that you disassembled with the rag and soapy water. Rinse and wring out the rag often while cleaning the fan parts.

Set the fan parts on a towel to dry. You can help the fan parts dry quicker by wiping each part down with a dry rag. Make sure that there is no moisture on the fan parts before reassembling.

Put the fan back together by using a reverse order of the instructions for disassembling the fan.

Look for in an Oscillating Tower Fan

Offices, homes and schools all have the tendency to overheat with an overflow of people, or when the summer months bring along a heat wave. Traditionally, box fans and floor fans have been placed in such areas. However, fans that provide a higher level of cooling and comfort—fans that can spin 360 degrees—are currently en vogue, as they provide the best value on the market. Choosing the right oscillating tower fan depends on the features you find important.

Remote Control

When a room is uncomfortably warm, falling asleep can be difficult. In offices, it may be a chore to interrupt your train of thought and get out of your seat to change a fan’s settings for optimal comfort. Some oscillating tower fans are equipped with remote controls that can alleviate such issues. Many remote controls contain advanced features for greater convenience and ease of use. Some companies, such as Honeywell, employ glow-in-the-dark lighting on oscillating tower fan remotes to improve use in the middle of the night. LCD displays and fan timers on the remote make remote-controlled tower fans an especially attractive option for individuals who wish to put a minimum of effort into fan use.

Washable Filters

Filters on air conditioning units need to be replaced frequently to prevent allergens from reentering the air in a living or working space. Oscillating tower fans often employ long lasting, washable filters that can be reused, saving time, and money. Some such filters can be machine washed while others require hand washing to achieve a dust-free cooling system. Washable filters are easy to remove, simple to wash, and take little time or effort to reinstall once cleaned, resulting in a quick and cost-effective solution to airborne allergens.

Programmability

Tech-savvy individuals appreciate the ability to program cellular phones, laptops and home security systems. Modern oscillating tower fans are programmable, utilizing buttons on the unit or the remote to control the everyday operation of the machine. Programming ensures that you can expect a consistent result from your fan, day in and day out. Fans can be set to turn on at intervals as low as one hour and as long as eight hours at a time, providing a feature that larger and more expensive air conditioning units tout, but at much lower prices.

Portable Fan Science Projects

A portable fan is a staple of life in hot climates or places that do not have air-conditioning. Portable fans are used in homes, offices, schools and stores. A fan is something that students can have access to easily and cheaply, and they’re easy to run, using minimal electricity. Therefore, students can use them in science experiments at any age level.

Fan-Powered Boat

“Can I make a portable-fan powered boat?” is a science experiment that students in grades three and up might do with a portable fan. A student needs a battery-operated fan and a small, flat boat. It might be a boat that he made or found, but it needs to be very light. It should be made out of paper or plastic. Using the battery-powered fan, students will try to figure out if they can make the boat move across the water. Some possible results include strapping the fan to the back of the boat and using the air movement to push the boat, or placing the blades of the fan into the water–providing that they are waterproof–and using the fan as a propeller.

Fans as Wind

“What Will the Wind Move?” is a science experiment in which the main point is to see what objects will be moved by a portable fan. Students can drop several different types of objects from a height in front of the fan, and see if the objects land directly on the ground or if they are moved by the wind. Objects might include feathers, pieces of paper, rocks, balls or peanuts. Students can experiment to see if the wind has a stronger effect on objects that are heavy, light, big, small, round, flat or any other descriptive that they would like.

Fans and Drying

“How Does a Fan Affect Drying?” is an experiment for any age level. In this experiment, student use a portable fan to try to dry liquids on different surfaces. Students might get two sheets of paper wet and hang one in front of a fan and hang the other in an area where the fan is not blowing, and then time them to see how long it takes for them to dry. Students might also place a shallow pan of water in front of a fan and another in a different area of the room, and then measure how quickly the water in both pans evaporates.

Pedestal Fan Works

Design

Pedestal fans are also considered oscillating fans. They have an adjustable metal stand so the head of the fan can be set anywhere from 2 to 4 feet off the ground. Also, the head connects to the pedestal on a platform which can be angled up or down. Inside, the fan head is comprised primarily of an alternating current electric motor with a secondary output which attaches to a worm gear at the base of the platform.

Single Speed Fans

Single speed pedestal fans primarily use a single-phase AC induction motor. The fan blade is attached to a spindle which extends into the motor. Inside the motor, there are two parts. The spindle, which ends in a free-spinning piece of magnetized iron, is known as the rotor. It splits by means of a CV joint so that a secondary spindle extends down from the motor to rest against the worm gear in the base. Sitting on either side are the two halves of what is known as the stator. Electricity is passed through both sides of the stator.

In proximity to one another, the ends of the stator create a shifting magnetic field, the poles of which change between positive and negative as the electricity continues to flow. Sitting in the center of this magnetic field, the rotor is forced to spin, turning both the fan blade and causing the fan to oscillate on its stand.

Multi Speed Fans

Multi speed pedestal fans are a little more complex, using a voltage regulator connected to a single phase AC synchronous motor. Because of its complexity, the fan head is bulkier, and the CV joint connecting the fan head spindle to the worm gear spindle is placed outside the motor, though still within the fan’s plastic casing. In this case, the rotor is not a single piece of metal, but a copper cylindrical cage called a squirrel cage which sits just within the stator, which is of the same squirrel cage design.

The voltage regulator controls how much electricity reaches the stator and rotor; the more power the faster the speed. Also, rather than splitting the available current evenly, slightly less power is sent to the rotor by means of a smaller gauge wire. This difference in electrical potential between rotor and stator generates a magnetic field, causing the rotor to spin and power the
