Most consumers have heard of the Dyson's consumer electronics company. They are famous for their products related to vacuum cleaners. They have come up with a new kind of fan, called the Dyson Air Multiplier. The Dyson Air Multiplier is a bladeless fan. Yes, no blades to throw air towards you. This fan looks like a circular hollow tube. This tube is mounted on a pedestal.
Working of a Dyson Bladeless Fan
If you have been able to catch a glimpse of the Dyson fan, you may have noticed that it looks totally different from a conventional fan. There are no visible moving parts and no blades that you normally notice in your fans. There is just a big 'O' attached to a long cylindrical tube that is in turn attached to the base. So, how is the bladeless fan able to push air towards you? Thus arises the question about Dyson Airfoil fan: how does it work? Let us see the basic principle behind Dyson Airfoil fan: how does it work in the following paragraph.
A new advanced technology is based behind the working of the Dyson fan. It works just like the way airplane wings work. It uses an airfoil shaped ramp that is placed in a cross-section. There are blades in this fan too. However, these blades are placed in the base of the fan, thus remain invisible. It uses about 5.28 gallons of air per second. It draws in the air using a very efficient brushless motor. Applying a few scientific principles used in jet engines and turbochargers, the fan is made to work efficiently. With the help of an annular aperture, the airflow of the fan is accelerated. When the air passes over the airfoil shaped ramp, it is channeled towards a specific direction. A process called inducement takes place, in which the air behind the Dyson Air Multiplier is drawn into the airflow. Entrainment is another process that takes place where air from around the machine is also drawn into the airflow.
The airflow comes in contact with a circular shaped part of the fan called the mixed flow impeller. The mixed flow impeller is placed in the cylindrical structure. This impeller works like an air pump and blows the air upwards. This upward directed air reaches the ring, from where it creates a negative pressure. This negative pressure occurs above the ring and cylinder joint. The air that is present behind the ring is pushed forward due to the negative pressure. This leads to development of a negative pressure behind the ring. Thus, the air starts flowing from the back to the front. This process is called the Coanda effect. The direction of the air flow is forward in a circular cross-section. The air present around the air flow also begins to move due to viscous shearing. Thus, the airflow is amplified about 15 times.
Dyson Fan Review
The Dyson fan reviews are very positive as this fan has many advantages. The first and foremost advantage of a Dyson fan is the safety factor. You no longer have to worry about kids poking their fingers or getting their hands caught in blades when the fan is switched on. As there are no blades attached to the fan, it proves to be a safe option for families with kids and pets. The second advantage of this fan is that it is extremely easy to clean. The fan has a very easy to clean, simple design that can be cleaned by almost anyone. When compared to other fans, the Dyson fan has the ability to oscillate the airflow upwards as well as downwards. This is because when you have a look at the Dyson fan, you will notice the center of gravity is very far from the base of the fan. The air from ordinary fans is usually chopped off due to the blades, thus making the airflow a bit rough. Dyson bladeless fans correct this problem as there are no blades thus making the air flow very smooth. What's more in the Dyson fan review? Noise level. The fan is rather silent and is not louder than your conventional fans. You can have a peaceful sleep while the Dyson fan is switched on.
Dyson Fan Price
The Dyson fan price is thought to be a bit expensive as compared to other conventional fans. The price of this home appliance is about $299. However, if you go through the advantages of having a Dyson Air Multiplier fan, you will find that $299 is worth the bargain.
There are lot of advanced scientific principles applied for working of the Dyson fan. The above paragraphs is the most simple explanation for a common consumer to understand. Hope you have been able to understand more about the Dyson Air Multiplier fan and made up your mind for investing in this unique and ascetically beautiful fan.
