The most common devices designed to overcome the debilitating summer heat are fans and air conditioners in Mippin. Many people perceive fans as a relic of the past, believing that they have hopelessly lost their effectiveness against the background of modern air-conditioning systems. Air conditioners really cool the room in a relatively short period of time, however, unlike fans, they do not differ in mobility, require complex installation work and, moreover, often provoke the development of colds. And given that air conditioners are not cheap, sometimes the choice in favor of the fan becomes obvious.
The most reliable and convenient device for home use is considered to be a floor fan, which provides maximum cooling even in large premises. They are different, so the “Dream House” offers to understand the types of fans and the principles of their work, in order to facilitate the selection of an appliance for cooling an apartment, a house or an office.
What are the floor fans?
Floor fan is a design on the leg, the height of which, often, can be adjusted. In addition to adjusting the height, often modern manufacturers leave the opportunity to change the angle of inclination and rotation of the fan itself so that you can choose the most comfortable angle of blowing.
The radial fan of air for the house possesses a more difficult and perfect mechanism. The design of this device is equipped with a rotor with curved blades that move the air, pushing it back into the room. The air processed by the radial fan has pressure and, like a light wind, spreads around the room, cooling even the not blown zone.
What to look for when choosing a floor fan?
Regardless of the degree of equipment with additional functions, the fan will cool the room qualitatively only if its power corresponds to the dimensions of the space being blown. The power of modern floor fans ranges from 30 to 140W. As a rule, for rooms of standard size, it is quiet enough that the device has a power of from 50 to 80W. If you purchase an axial fan, first of all, pay attention to the diameter of its blades, which determines the intensity of the blower. In addition, for safety reasons, the blades of the structure must be protected by a solid, fine mesh.
How to choose a good fan?
During the summer heat, many modern residents of large cities seem ready to give everything away so that the house is cooler. However, not everyone can afford an air conditioner, which is why cheaper devices are fans today and are more common. It is commendable that modern fans are much less noisy than their predecessors another trump card in favor of the choice of fans.
There are four criteria for evaluating a fan. The first criterion is the type of fan. In total, there are four types of such devices column, table, floor, and fan heaters. Floor devices are quite large. In such fans can adjust the height of the location and the angle of the device. In addition, the user can select the operating mode horizontal or vertical.
The most compact and lightweight fans – desktop. They are good, such devices can be moved almost anywhere, and anywhere to put. Lack of devices they are not as productive as, for example, the same floor fans. Column fans are large and cylindrical in shape. Such devices can only rotate horizontally. Another feature using such a fan, you can independently regulate the flow of air. Fan Heaters the latest subspecies of devices in this collection. Choose them if you need a “two in one system” the fan, coupled with a heater. Such a device will be able to work both in the cooling mode of the room and in its heating mode.
They are made of heat-resistant materials and are equipped with overheating protection. If we talk about the fan operation mode (the second selection criterion), then the rotational speed, the plane of rotation and the angle of inclination of the device are taken into account. The third important criterion for choosing a fan is the airflow rate.
Variety of a floor fan model:
Today, fans are used everywhere to supply fresh air to the premises. Many people constantly work alongside them, but not everyone knows what features these devices have. In short, a fan is a device for moving air, providing a pressure difference or some degree of compression at the air inlet and outlet. Most often, the fan consists of a rotor on which the blades are fixed. The rotor rotates the fan blades begin to throw air. It is comfortable with a sleeping mask. During fan operation, a thrust or air pressure is created, so fresh air is supplied to a room equipped with this device. When buying a fan, you should definitely pay attention to the position of the blades, as well as their shape this determines the direction in which air is thrown when the fan is running. Fans are classified according to several criteria. By design, they are axial, centrifugal, and diametrical.
The blades of an axial fan move air along an axis around which they themselves rotate. It is worth noting that today the axial fan devices are the most common they are quite simple to manufacture, moreover, with the operation of such a fan, the movement of the intake and discharge air coincides. Such devices are used for cooling electronics, in everyday needs in apartments and houses, they are also installed in turbofan aircraft engines. In addition, there are centrifugal (they are also radial) fans. In such fans, the blades have a spiral shape.
The air through the inlet enters the rotor, there it acquires a rotational motion, and then, due to centrifugal force, is sent to the outlet, which in such fans is located at right angles to the inlet. Typically, devices of this type are widely used in the industry. The third type of fan is a fan of diametrical cross-section; it is usually carried out in the form of a cylinder, in which instead of walls there are rows of forwarding curved blades. Air is drawn along the entire length of the case from the front side of the fan. Such fans are usually installed in air conditioners. Finally, there are fans at all without blades. The airflow in them is formed by a turbine hidden in the base.
