Household Fans Demystified
Fans are appliances that are used to produce airflow for the purpose of climate control, ventilation, or exhaust, and they can come in the form of any type of vane used for producing air currents.
Fans have been used since antiquity for applications such as personal comfort, climate control, removing dust, drying, and to provide drafts for fires. The first mechanical fans were those found in the Middle East in the 1500s called punkahs. These consisted of canvas-covered frames that were suspended from ceilings, and servants operated these primitive fans by pulling a rope connected to the frame to move the device back and forth.
It wasn’t until the late 1890s to the early 1920’s that fans were widely used. Combining both style and practicality, these fans were usually constructed of brass blades and cages. However, these fans were quite unsafe, as the cage openings were often big enough to fit fingers or an entire hand, and subsequently, it was common for people to suffer severe injuries as a result of their use.
Nonetheless, with the rise of the Industrial Revolution in the 1920s, mass-produced steel fans were made in many different shapes, sizes, and styles, and these devices became more affordable and accessible to homeowners across the country. Since then, fans have become more utilitarian, but they still provide cooling comfort for countless people around the world.
With that in mind, it should be noted that ceiling fans are some of the most popular among homeowners, and these are devices that are powered by hub-mounted rotating paddles which circulate air to produce a cooling effect. These fans are suspended from the ceiling and are used in the summer to provide cooling comfort. In addition, they are also often used in the winter in a reversed rotation to move warm air from the ceiling, down walls, and onto inhabitants in the room.
The following are some general questions commonly asked by consumers regarding household fans:
Q: What are “whole-house fans” and are they useful?
A: Whole house, or attic fans are types of fans that are installed in homes and designed to push hot air out. With the flip of a switch, they pull cooler air from the outside through open windows and send hot indoor air through an attic. These can result in a five degree temperature drop in as little as five minutes. They can also be used to ventilate a home whenever the outdoor air is cooler – typically when the sun sets.
If properly installed, a whole house can cost-effectively bring the temperature down in your home, and when in the market for such an appliance, look for one that will fit between your trusses. Also don’t forget to pay attention to your air volume requirements.
Q: Is a fan really more energy efficient than an air conditioner?
A: If you’re looking for more air movement, use a ceiling fan or even a regular portable fan instead of relying on your air conditioner’s blower. Because air conditioners run about 50% of the time in the hottest days of the summer, this can cost much more to operate than leaving your ceiling fan on 24 hours a day, 30 days a month.
Also, depending on an air conditioner’s blower can sometimes result in leaks in your duct system. In turn, this can add more heat to your home, as hot air from the attic will be introduced into the air stream.
Q: Why should I use a ceiling fan in the winter?
A: It’s important to understand the temperature in a room varies in layers – the air near the ceiling is always warmer than the air near the ground due to the rising of warm air. With that in mind, ceiling fans can push warm air near the ceiling down the ground, and as a result, the heating system is not overworked when warming a room.
To use a ceiling fan during the winter, be sure to set the fan to run in a clockwise direction, as this will push the air up against the ceiling and down to the walls. Doing so will often help slash your energy bill by as much as 10% in the winter.
Q: Why is it necessary to use an exhaust fan?
A: In addition to small leaks and cracks found around openings such as doors or windows, the duct work used to distribute warm or cool air in your home will always be prone to some degree of leakage.
