Guide to Fans: Types, Costs, Proper Use, and Alternatives

Fans are appliances that circulate air to provide a cooling effect in various settings. Fans play a crucial role in providing air cooling and circulation in homes, offices, and outdoors. The versatility of fans makes them a popular cooling solution to improve comfort and air quality.

There are several types of fans that help keep you cool under different conditions. Firstly, large upright fans such as tower fans, Dyson fans, and pedestal fans are useful in large rooms or for cooling large groups of people. Secondly, small fans such as neck fans, desk fans, hand-held fans, and cooling fans work to supply air to small areas directly. Finally, mounted ceiling fans, kitchen extractor fans, and bathroom extractor fans offer permanent air circulation solutions to large and small areas with niche purposes.

Fans cool the air by evaporating the moisture from the air and skin, which lowers the body temperature by providing a cooling sensation. The different types of fans work by using an electric motor to spin blades called impellers, generating airflow by pushing or pulling air. The impellers force air from one area to another to circulate air throughout a space.

The cost of running a fan can vary depending on the specific model, its power consumption, and the duration of use. To calculate the cost of running a fan, you can multiply the wattage by the number of hours used and the cost of electricity per kilowatt-hour (kWh), but the price varies depending on your electricity provider. Additionally, situational factors impact the cost of running a fan. For example, the position of a fan in a room will determine how effective it is at cooling.

The best locations for a fan depend on the area that needs to be cooled and the available space. For example, a pedestal fan works well to cool a large area with poor ventilation if it’s placed opposite a doorway. The active flow of air pushes the stagnant air from the improperly ventilated room and circulates air from outside the room, providing a cooling feeling. Additionally, a tower fan near an open window will pull fresh air from outside to circulate within a room.

Fans are cost and energy efficient but not all scenarios call for the use of a fan. There are three main cooling system alternatives to fans that are capable of providing similar cooling effects. Firstly, air coolers are devices that use cool water or ice to humidify the air. Secondly, air conditioners are cooling systems that use refrigeration to lower the temperature and dehumidify the air. Thirdly, air-source heat pumps heat and cool spaces by transferring air between indoors and outdoors. Additional alternatives to fans vary depending on their intended use. For example, sleeping with a fan on can warrant alternatives such as natural ventilation, or cooling mattresses, sheets, and pads.

Fans are a cost-effective and efficient cooling solution that suits a variety of purposes. Below, we explore the different types of fans, how much fans cost, the proper uses for fans, and alternative cooling solutions.

How does a fan work?

Fans work by utilising electric motors to rotate blades which in turn circulate air and create a cooling breeze. Depending on their design, the blades of the fan push or pull air, which generates an airflow that helps to evaporate moisture from our skin, making us feel cooler quicker. Additionally, the movement of air created by a fan creates a wind-chill effect, providing a refreshing sensation over the skin. Fans are a popular and energy-efficient way to cool down during hot weather because of their practical use and convenience. However, fans are incapable of preventing heat-related illness, such as heat stroke, in ambient temperatures above 35 degrees Celcius.

Below are four examples of different types of fans and how they work.

• Ceiling fans: Ceiling fans are mounted on the ceiling and consist of a central motor housing with attached blades. They work by using an electric motor to rotate the blades in a circular motion, pushing air downwards and around the room. The downward airflow creates a cooling effect by increasing evaporation from our skin, making us feel cooler. Ceiling fans are effective in circulating air throughout the room, providing a gentle breeze that can help regulate the environment.
• Tower fans: Tower fans are tall and slim, resembling a tower or pillar. Tower fans draw air in through the base of the unit and propel it upwards using an electric motor and a vertical fan assembly. The vertical design allows for a wider area of air circulation, making them effective in cooling a room. Tower fans offer a more focused and targeted airflow, providing a concentrated cooling effect in a specific direction. They often come with additional features such as oscillation (rotation), multiple speed settings, and remote control functionality.
• Dyson fans: Dyson fans, known for their innovative technology and sleek design, utilise the Air Multiplier™ technology. Instead of traditional blades, Dyson fans have a hollow ring that draws in air through the base. The air is then amplified and accelerated through the ring, creating a powerful stream of smooth airflow. Dyson fans provide consistent and evenly spread cooling throughout the room. Their bladeless design ensures the safety and almost silent operation. Dyson fans also come with features like oscillation, multiple speed settings, and remote control functionality for personalisable use.
• Extractor fans: Extractor fans are typically used in kitchens, bathrooms, and other areas where extra ventilation is necessary.

Fans play a vital role in cooling and air circulation, but not all types of fans are suitable for every situation. Understanding how a fan works gives you insight into choosing the right product for your needs.

How does a fan blow cold air?

A fan blows cold air by circulating the air in a room. Fans don’t blow cold air like an air conditioner, instead, they create a cooling effect. The blades, or impellers, of a fan, rotate in order to push or pull the surrounding air. As the air moves, it works to evaporate moisture from our skin, making us feel cooler. The evaporative effect creates a sensation of cold air, even though the temperature of the air effectively remains the same. By increasing air movement, fans enhance the evaporation process, providing a refreshing breeze that can make us feel more comfortable in warm environments.

Do fans cool a room?

No, fans don’t cool a room. Fans do not actively cool the air in a room like an air conditioning system does, but they create a cooling effect by improving air circulation and increasing sweat evaporation. Fans circulate the air to move the heat away from our bodies and accelerate the evaporation of sweat, which cools us down as a consequence. The movement of air can make us feel cooler and more comfortable in a room, even without lowering the room temperature. Fans are particularly effective in smaller spaces and when used in conjunction with open windows or ventilation to promote the exchange of fresh air.

Where to put a fan to cool a room?

Put a fan in a location where the breeze reaches the most people. Proper placement of a fan in relation to the layout of the room is crucial to effectively cool a room. For the best circulation, a fan should be placed opposite an open window or another entry point for fresh air. Access to fresh air will help to displace hot air and draw in cooler air from outside. The fan should also be positioned at least 3 feet away from walls and other objects, so as not to disturb airflow. Additionally, the fan should be placed at an angle that will direct airflow towards areas where it is needed most, such as the sofa, desk, or bed. It is also important to keep your fan free of dust and grease, as this will clog the rotor blades and impede proper airflow.

Below are four tips on where to put a fan to cool a room.

• Place the fan near a window: Positioning a fan near a window allows it to draw in cooler air from outside and circulate it throughout the room. Placing the fan near a window is especially beneficial during the cooler parts of the day or at night when outdoor temperatures are lower.
• Point the fan towards the centre of the room: Directing the airflow towards the centre of the room helps to evenly distribute the cooled air and promotes better circulation. Pointing the fan towards the centre of the room helps create a more comfortable environment throughout the entire space.
• Use multiple fans strategically: Using multiple fans in different locations creates cross-ventilation. Cross-ventilation involves placing one fan near an open window or door to bring in the fresh air and another fan on the opposite side of the room to exhaust hot air. This promotes air exchange and enhances the cooling effect.
• Consider the height of the fan: Adjust the fan’s height to target the airflow towards the desired level. Turn on the fan’s oscillation (rotation) feature in order to sweep the cool air across a larger area, allowing for better air circulation and coverage.

Fans help create a cooling sensation, but they do not lower the room temperature. Therefore, it’s important to combine fan use with other strategies like shading windows, using curtains or blinds to block out sunlight, and reducing heat-generating activities during hot weather.

How much does a fan cost to run?
