Natural processes of the environment often impose different situations on the people who live in a given area. Environmental processes result to environmental conditions which in turn form the weather of a given area. During the weather conditions, people face different challenges as each weather condition has its own effects on people. Hot weather, for instance, gives people a difficult time as they try to cope up with the high temperatures. During hot temperatures, people experience a great lack of comfortability due to the overrated levels of warmth than the human body could require. It, therefore, makes people be uncomfortable. As a result, people look for a solution to enable them to become more comfortable with the weather. People get very hot so they look for a solution to make their environment colder so they could increase their level of comfortability. People invent systems to make their rooms cooler and make their stay more comfortable, avoid sweating too much or getting burns due to increased warmth. High temperatures expose people to sun burns which make their feel painful. Additionally, people get thirsty very often which also makes them uncomfortable.
When it is hot, people experience hardships in doing their daily activities. When the sun is too hot, people always have difficulties moving from one place to another as it burns them. The property also tends to get damaged at a faster rate when it is hot than when the temperatures are low. People tend to perform their chores more slowly when it is hot as they get fatigued more quickly. When it is hot, people get tired quickly as their bodies try to deal with the increased heat that being directed to them. Property, on the other hand, goes through accelerated levels of wear and tear because of the heat. As a result, people experience more losses that when it is cold. It, therefore, gives people a burden of making sure that their property is not exposed to high levels of heat. High temperatures also give people headaches and rashes on the ankles.
People try to find solutions to make their environments cooler, make their lives easier and prevent their properties from tearing and wearing. To make their rooms cooler, people could for instance use cooling fans. Ceiling fans are generally designed to perform the function of blowing cold air into a building which reduces the prevailing temperatures (Ghosh, 2014). The ceiling fans rotate continuously which then forms an air breeze in the respective surroundings as well as enhancing the rate of the heat transfer. A ceiling fan makes a room become cooler as the increased rate at which it makes people to sweat. When people sweat at a relatively high rate, the bodies undergo a cooling process a bit faster than when there is no fan. Modern ceiling fans cannot be closely compared to the old way of using a series of paddles and motor which were used to push around the needed amount of air. Modern ceiling fans in the present are constructed with the aeronautical skills from the respective engineers as well as fluid dynamists who participate to increase the efficiency of ceiling fans (Ghosh, 2014). Aerodynamics specialists also enable the engineers to make ceiling fans that are quiet.
Ceiling fans are constructed with a number of features that enable them to operate as well as perform their respective purposes successfully. Some of the features that determine the functionality of ceiling fans include its tip design and the length of its blades among others. Fan blades perform the function of turning and pushing air downwards which creates a downdraft which in turn makes a room cooler Schaur, Gil. (2013). The direction towards which the fan rotates determines the direction it pushes air towards. The aerofoil of the blade’s cross section, on the other hand, determine how smoothly the air from the blade flows. A flow that is not smooth makes the amount of air moved to reduce as well as making it noisy. Blades also need to be even and smooth. Even and smooth blades enable the fan to be more efficient.
A blade also performs its works depending on how its blade’s tip is made. A fan’s blade tip should be turned upward to avoid air to escape to the top surface. Additionally, the number of blades that a ceiling fan has determined its functionality (Schaur, 2013). Too many blades on a fan make the flow less efficient as they risk them moving through the turbulence of each other which results in a noisy rotation as well as reduced efficiency. The standard number of blades on a fan can be 3-5. Blades’ width and length also affect the performance of a fan. Bigger blades tend to result to faster and noisier the tips rotate. Large blades may also affect the room’s lighting plan. Narrow blades also tend to function better than the wide blades. All the functions of fan blades should aim at coming up with a fan that has a high speed of rotation.
Standard ceiling fans provide their users with the efficiency of being used in flat as well as sloped ceilings. Standard ceiling fans can be used in buildings that are 8 feet or more so that they are not less than 7 feet above the ground. Standard ceiling fans tend to be more powerful than other types of ceiling fans which make their uses wider as well (Bermudez, 2013). Standards fans happen to be the best rated as they are more effective than the other types of ceiling fans. Low profile ceiling fans, on the other hand, are installed directly to fan’s mounting bracket. Low profile ceiling fans can be used in rooms that have a height of 8 feet or less so that they are placed not more than 7 feet above the ground. Low profile ceiling fans tend to be less powerful than the standard fans as they serve a shorter height than the latter. The low profile fans could, therefore, be used at home while the standard fans can be used in larger buildings with more people (Bermudez, 2013).
Ceiling fans are mainly aimed at serving those people who live in the tropical areas, deserts and the hot regions among other places that tend to experience high temperatures. Ceiling fans cannot be said to be made for a specific building or people of a given occupation as people in all walks of life need to make their environment conducive for their stay (Bermudez, 2013). Ceiling fans can be used by people anywhere in any type of building with its features regulated to suit the building it is installed in. people specify the functionality they prefer on fans and therefore they can choose the type of blade that they think serves their interests in the best way. Office workers can use ceiling fans to make the working environment comfortable while hospitals can install fans to make patient’s environment conducive to their recovery. People can also install fans at their homes to make their lives more comfortable and avoid high temperatures in their houses. Fans can also be used in machines like computers to regulate their temperature when they are on (Bermudez, 2013). The Emerson Carrera Grande Eco Montecarlo turbine tends to be the most prominent brands of standard ceiling fans. The Havells and Usha brands, on the other hand, are the best for the low profile ceiling fans.
