Why You Should Install Ceiling Fan? 為什麼要安裝吊扇?
There is only one thing constant in this world and that is change. The changing times also changed the taste and preferences of people which moved from hand fan to ceiling fan to coolers to air conditioners. But there are few things that retain its magnetism and utility withstanding the tests of time. Ceiling fans are one of those things which are still preferred by many because of its aesthetics, money saving and space saving capacity, its environmental conditions as well as for its convenience.
世界上只有一件不變的定律就是變化。時代變遷也改變了人的口味，現在從地扇轉用到天花風扇再轉用冷氣。但實用經受了時間的考驗。吊扇就是這些東西，仍然是許多人的首選，因為它美觀，能節省金錢，節省地方，以及環保及方便。
Some ceiling fans can even be further customized and can also be provided with or without built in lighting be it spot light or diffuse light or frosted glass or any other and this overhead light is ideal for a playroom or dining room or any other place of choice. Besides it is attractive, it is also practical for all classes and an energy saving device. Even if there is a central heat or air conditioner installed in the respective room or hall, the ceiling fans help lower the energy consumption and the electric bill thus contributing to the savings of the household as it lowers the room temperature by eight degrees as per facts noted. And unlike an air conditioner which requires regular servicing to function properly, the ceiling fan does not require a lot of maintenance apart from regular cleaning.
有些吊扇可以因個人化設定，也可以安裝或不安裝照明燈具，光線可以是聚焦光或散光或磨沙玻璃，這些附加燈在遊戲室或餐廳或任何其他地方提供理想的光線。除了吊扇很有吸引力，這對任可地方也是實用及帶來節能用途。即使安裝在各個房間或大廳的中央再開著其他暖氣或冷氣，吊風扇有助於降低能源消耗和電費從而促進了家庭的儲蓄，因為它能降低室內達5度。不像冷氣機般，需要定期保養才能正常運作，吊扇並不需要大量的維護，但必須定期清潔。
Benefits of ceiling fans
As they reduce energy consumption they are in turn environmental friendly as well as it reduces carbon footprint. Moreover, to personnel with allergies ceiling fans are better than central air conditioning as moulds can grow in vents and ducts if not properly cleaned and serviced on a regular basis. Ceiling fans are similar to floor fans with the added advantage of space clearance and they provide inherent safety as well with children and pets which is certainly not the case in standalone units.
吊扇燈能減少能源消耗又環保，及它亦能減少碳足跡。此外，冷氣如果沒有正確的清潔和保養，過慮網可以在通風口和管道增長細菌，對有過敏症的人有影響。吊扇與坐地扇相似但有更附加優勢，就是吊扇比較節省空間，吊扇對兒童和寵物更能提供的固有安全性。
Another aspect is that its wiring is nicely hidden from the view unlike standalone units which involve long cords laid across the floor for tipping and other hazards. Moreover, the blades of ceiling fans differ in length and the longer the blades of the fan, it provides better and wider circulation especially for larger rooms. There are even such models available that are remote control operated which adds to the convenience of ceiling fans with its capability to adjust added lighting, fan speed, switching it on or off or any other feature that accompanies the automation.
另一方面，它的電線很好地隱藏起來，與坐地扇不同，在地板上鋪設了容易傾翻等危害的電線。此外，吊扇葉片的長度有所不同，越長的風扇更能提供更好的和更廣泛的空氣循環，特別對於較大的房間更為有用。有些吊扇可用遙控器控制，更增令使用時帶來方便，其功能開關附加燈飾照明，風扇轉速，或任何其他附加自動功能。
How Does Ceiling Fan Cools Down A Room? 吊扇怎樣降低空間溫度?
How Does Ceiling Fan Cools Down A Room?
Simply love those ceiling fan? Living in a hot and humid climate such as Hong Kong, it is necessary for one to possess a device or some way of cooling oneself down or lowering the temperature of the area around the person, especially in an enclosed area. Technology has blessed us with a variety of gadgets to do so, such as the air conditioner, standing fan and ceiling fan. Then there’s also the traditional way of cooling yourself down, using a hand-made fan to fan yourself. However, in this article, we will be discussing about an age old traditional gadget which has withstood the test of time and still in use nowadays – the ceiling fan.
愛上吊扇燈？生活在炎熱和潮濕的氣候，例如香港，需要一個冷卻設備降低周圍的溫度，特別是在一個密封的區域。科技已經賜給我們的各種小工具，例如冷氣，坐地扇和吊扇或手工製作的紙扇。然而，在這篇文章中，我們將討論的一個古老傳統的小工具，它已經時間的考驗，至今仍在使用 – 吊扇。
Ceiling fans originated from United States of America in the mid-19th century and has been in used throughout the world since then. Hong Kong is no exception and ceiling fans are still a common sight within Hong Kong. You can still see them at coffee shops, hawker centres, some traditional shop houses, and even at some peoples’ houses. Despite the fact that ceiling fans are still widely used, few people really understand how it works and how it cools down a room. On the surface, it seems like you just switch on, and the blades will start turning and this in turn will result in cool air and breeze being produced. To change the strength of the fan, either adjusts the knob by the side or to pull a string attached to the ceiling fan. Superficially, it will appear like this to many people. So how does it work exactly?
吊扇起源於美國，在19世紀中期以來，已經在世界各地使用。香港也不例外，吊扇仍然在香港隨處可見。你仍然可以看到他們在咖啡店，舖頭，或一些住宅。儘管吊扇仍在廣泛使用的事實，很少有人真正了解它是如何運作，以及它如何冷卻的空間。表面上看吊扇開著後，風葉開始轉動，這樣會導致涼爽的空氣流道和產生微風。扭一下牆上開關或拉一下拉繩，可調節快慢速，從表面上看，這樣理解的人不少。那麼它是如何工作是什麼呢？
Basically, the above superficial answer is a pretty good summary as to how a ceiling fan works. A ceiling fan is made up of a few key components, the power source which is the switch, the motor, and the fan blades. When the switch is switched on, an electrical current will be generated and it will travel towards the fan motor. Through the movement of the electrical current near the motor, a magnetic field will be generated and it will exert a force on the electrical energy circulating the motor, converting it into mechanical energy which will in turn be transferred to the coils which is attached to the blades, causing the coils to move. The turning motion of the coil will result in the blades to move as well and this is what we see – the spinning of the fan blades. The spinning motion of the fan blades will create an air draught, which causes cool air to sink and hot air to rise. This allows us who are under the fan to feel the cool breeze generated and cause air to circulate within the designated area. Do note that a ceiling fan doesn’t lower the temperature of the surroundings like an air-conditioner, but it just causes air circulation and a cool breeze.
基本上，上述的顯淺答案是一個很好的總結，吊扇是如何運作的。吊扇是由幾個組件組成，所述的是電源開關，馬達和風扇葉片。當開關接通時，向馬達產生電流，令風扇轉動。通過電機附近的電流的流動，產生磁場，施加對電能的動力循環的馬達，將其轉換成機械能這將反過來被傳輸到連接到線圈葉片，造成線圈移動。線圈的轉動運動將導致葉片移動，以及與這就是我們看到的風扇葉片旋轉。風扇葉片的旋轉將產生一個空氣氣流，這導致冷空氣下沉，熱空氣上升。這使得我們感覺到的涼風，造成在指定區域內空氣流通。請注意，吊扇不能像冷氣般將周圍環境溫度降低，但它只是使空氣流通和涼爽的微風。

Air-Conditioner vs Ceiling Fan 冷氣vs吊扇
Ceiling fans are the bread and air conditioner are butter in nowadays Hong Kong. They are commonly seen outdoors in shopping centers and restaurants or house patios. They are the number one indoor and outdoor cooling device, and works differently from the more appealing air conditioner. A ceiling fan generates the surrounding air flow while the air conditioner lowers the temperature of the surrounding air to balance evenly around the area. Furthermore, an air conditioner is mounted on the side of the wall while the ceiling fan is installed directly above us which air travel all over 360 degrees.
現今香港，吊扇是麵包冷氣是牛油。是在室內和室外餐廳或庭院的房子常見的戶外產品。它們是室內和戶外的冷卻裝置。與冷氣的作用不同。吊扇燈風扇燈能幫助周圍空氣的流動，而冷氣只能降低空氣溫度，但不能平均分佈於周圍區域去降低溫度。此外，空調只能安裝在牆上的單一面，而吊扇燈風扇燈能直接安裝天花上，讓風向遍布360度。
Hong Kong Red Hot Summer香港夏天
Hong Kong’s hot and humid weather during the summer and spring has been a torture. Ceiling Fans were used before air conditioning was invented. It is affordable, easy to install and operate. It provides substantial savings on energy and offers another alternative to air-conditioning.
香港春天與夏天悶熱的天氣一直是折磨。吊扇燈風扇燈的發明早於冷氣之前，它經濟實惠，而且易於安裝和操作。它能節省大量的能源和提供了另一種冷氣的替代品。
Many of us overlook the benefits and advantages of ceiling fans compared to air conditioners. Although after the introduction of air conditioning systems in the market the demand of ceiling fans has decreased but even today it is considered as the basic requirement of every home. The air conditioning systems not only consumes a lot of energy; it also doesn’t make your wallet feel good. Also, it is affecting the environment to a large extent. One of the reasons of increasing global warming is usage of air conditioners. Using air conditioners can also affect your health as it deprives you of fresh air. Cooling your house with ceiling fans can be healthy as well as save money and energy.
相對於冷氣，我們很多時忽略了吊扇的好處和優勢。自從冷氣推出市場後，吊扇的需求有所下降，但是在今天，吊扇被認為是每一個家庭的基本要求。冷氣系統不僅消耗了大量的能源;它也會令你的錢包感覺不良好。另外，還影響環境，在很大程度上。其中增加全球暖化的原因是冷氣的使用。使用冷氣也可以影響你的健康，因為它剝奪了新鮮空氣。吊扇冷卻你的房子可以是健康的，以及節省金錢和能源。
The process of ceiling fans makes your environment cooling by at least three degrees which means that thermostat can be set at a higher temperature to save on energy costs! It is not only for airy purposes but also stylish for home decorations.
使用吊扇燈風扇燈時室內溫度能至少降低3度，這樣冷氣便可以被設置在一個較高的溫度，節省更多能源費用！吊扇燈風扇燈不僅是有空氣對流的作用，而且還是一種時尚的家居裝飾品。
Looking at all the benefits of the ceiling fan, one should try to avoid the usage of air conditioners and take full advantage of the ceiling fans.
看著天花的風扇帶來的好處，應該盡量避免冷氣的使用和採取的吊扇充分利用。
Ceiling Fan vs Table/ Floor Fan 吊扇vs枱扇地扇
There are various types of fans available in the market. There are the standings fans, where they can stand on the floor or bay window, and those shorter standing fans or box fans that can be placed on tables. Standing and box fans are convenient as they can be moved easily from place to place where wind is required.
市場上有各種類型的風扇可選擇。有企身地扇，他們可以被放置在地上或窗台上，而那些較矮身的風扇或鴻運扇則可以放在檯面上。企身扇和鴻運扇很方便，因為他們可以很容易地從一個地方移動到另一個有需要的地方。
On the other hand, ceiling and wall fans are fixed to the ceiling and wall, respectively, thus restricting their mobility. However, standing and box fans take up space and seriously look out of place in an elegantly designed room! Both wall and standing fans are similar in how they blow the air i.e. they blow the air forward and as they oscillate, the air will be circulated around the room. Ceiling fans blow the air downwards and circulates the air within the location it is mounted, making the room breezy and cool.
另一方面，天花和牆身風扇被固定在天花板和牆壁，因而限制了它們的流動性。然而，企身扇和鴻運扇佔用空間，它們在一個設計優雅的房間太過礙眼！而牆身和企身的風扇都的風向只是吹向前方，氣流只能夠到達其搖擺時所能到達的位置。吊扇之氣流卻能不段向下循環，為房間帶來陣陣的涼風。
How to Clean Ceiling Fan 怎樣清潔吊扇
- 確保風扇電源完全關上，然後才作任何清潔或維護。
- Because of the fan’s natural movement, some connections may become loose. Check the support connections, brackets, and blade attachments twice a year. Make sure they are secure. (it is not necessary to remove fan from ceiling.)
- 有時候，由於風扇自然運作上了一段時間，或會有些連接位可能會鬆動。建議每2年檢查吊扇支持連接部份，支架，和葉片連接附件等。確保他們的安全。（這是不需要把吊扇從天花板上拆下。）
- Use only a soft brush or lint-free cloth to clean your fan periodically to avoid scratching the finish. The plating is sealed with a lacquer to minimize discoloration to tarnishing. Do not use water when cleaning, this could damage the motor, or the wood, or possibly cause an electrical shock.
- 使用軟刷或無絨抹布或除塵紙定期清理你的風扇，切勿使用清潔劑以避免刮傷塗層。因吊扇用了電鍍封閉漆，以減少變色。清潔時，不要使用水，這可能會損壞摩打或令木扇葉受潮而變形，或可能會導致觸電。
- There is no need to oil your fan. The motor has permanently lubricated bearings.
- 風扇是無需添加潤滑油的。電機是具有永久潤滑軸承。
Ceiling Fan Blades Material 吊扇風葉物料
Ceiling fans are made of different materials e.g. plastic, wood and metal and come in various designs.
Acrylic blade fans 塑膠風葉
You can also look for acrylic. Acrylic material has the capacity to resist moisture and thus prevents the blades from getting corroded. Thus usually outdoor usage with undercover. This would help in prolonging the life span of the fan.
塑膠造風葉: 塑膠風葉擁有抵抗潮濕水氣功能，所以風葉較難腐蝕，多用於有蓋戶外使用，壽命亦較長。
Wooden blade fans
Wooden fans provide that extra bit of safety when compared to the Acrylic fans and Metal fans. Most of the wooden fans come in the form of three, four blade fans and five blade fans.
木造風葉比塑膠或金屬較為安全。多數以3,4,5葉出現。
What Ceiling Fan Size is Right for My Room?
什麼吊頂風扇尺寸是適合我的房間？想要為您的家庭安裝吊扇？吊扇可以有效的替代費用較昂貴的空調。風扇在開機時能直接有冷卻的效果，有時候連空調也未必能做到。大部份時間，當我們選擇時我們都只會顧及款式，以配襯我們的家居裝飾中，但對於選擇相對合適的吊扇大小，我們往往不知所措。
Does size matter? You bet it is, and it is important to know that ceiling fan size is just one of the many vital factors that determine whether you will get the effects you want. Therefore, please give some thoughts to the various factors can put you to the right decision.
Among the many guidelines, the golden rule to follow is to choose the biggest fan that will fill your room without appearing too overpowering. Smaller fans can’t stir up the same airflows as would bigger ones, and air circulation will therefore not be as effective. Where conditions permit, allow yourself a bigger one. It is worthwhile to invest just that little more so that everyone experiences lesser discomfort and stay happier.
吊扇大小重要嗎？那當然是很重要的，吊扇大小能決定你是否會得到你想要的效果。因此，請細心想一想各種因素可以令你作出正確的選擇。
選擇正確吊扇的黃金法則是跟據你房屋的大小去挑選。如空間許可，可以選擇較大的吊扇，尺寸較小的吊扇是不及尺寸大的可以做到更大的氣流，因此，空氣流通不及尺寸大的吊扇有效。如條件許可，讓自己挑選一個更大的。這是絕對值得的。
When we position ourselves under the moving blades of ceiling fan, we experience the most effective cooling sensation that it can produced. This air rotation that the blades produce becomes increasingly less felt when we gradually drift away from this position. At about 0.6 meters away, this airy loss becomes very pronounced. What this means is that you may be placing your fan directly in the middle of your room, but if you are placing your sofa set 1.2 meters away from it, you’re in for a big disappointment. It goes to say that apart from room size, where you install your fan will also determine whether you will get the cooling effect you required; your room layout is just as important and you need to give some thoughts to it.
當我們身處於吊扇的葉片之下，我們可以直接享受它所產生的清涼效果。而當我們漸漸遠離這個位置，清涼的感覺便會漸漸減少。在距離吊扇約0.6米，風力減弱已經會變得非常顯著。如你把吊扇直接安裝你的客廳的正中間，與沙發的距離1.2米，你會對於你的吊扇感到失望。因此請注意，除了房間的大小，在您安裝的風扇的位置也將決定吊扇帶來的冷卻效果；安裝吊扇的地方與房間設計佈置都是一樣的重要。
The next thing to consider has something to do with visual feel. Do you know that colors can play tricks to your eyes? If you are not careful, the wrong mix can put things to your disadvantage. Conversely, if you use them well, you can turn things around and dramatically improve the situation. Let’s assume that you have a room that is not very big, which has a ceiling that is not too high or not too low, just the usual type. If your furnishings are all in dark browns and you choose a fan of the same color tone, hoping that it will blend well with your settings, you are in for a surprise. The fan appears as though it is just above your head. This is worst if ceiling is also coated with the same color, but of course no one is going to do that.
接下來要考慮的就是視覺感受。大家知道色彩是可以矇騙你的眼睛？不小心把顏色搭配錯誤，將會突出其缺點。相反，如果使用得宜，可以扭轉乾坤，並顯著改善。讓我們假設你有一個房間，不是非常大，樓底不是太高或不太低，屬於一般的類型。如果你的家具都是深棕色而又選擇相同色調的吊扇，希望這樣能夠融合了你的設計，這其實是錯誤的； 因為吊扇看起來好像在你頭上而變得平平無奇。
To make the fan appear higher, it is better to choose one of a smaller size. But your next disappointment will be the weak airflow that the smaller fan is driving. You can however, easily get around this problem by getting a usual size fan that shares the same color scheme as your ceiling. In this way, you can eliminate the false illusion of an over lowly mounted fan and at the same time enjoy the good moving air from a little bigger fan.
為了讓吊扇看起來沒有壓迫感，最好是選擇一個較小尺寸的吊扇。但是，較小尺寸的吊扇，氣流亦會相對地較為微弱。如你家中的樓底不高，而你又想解決吊扇壓迫感的問題，你可以選擇與天花顏色一樣的吊扇燈。雖然這樣可能令吊扇變得有些平平無奇，但你便不需局限於選取尺寸較小的吊扇，又能享受到合適大小的吊扇為你帶來的最佳效果。
Safety concerns with installation 安裝安全問題
一個典型的吊扇的重量為15磅和50磅之間，安裝吊扇會用兩個爆炸螺絲繫於混凝土天花板上。安裝吊扇的另一問題涉及風葉相對於地面的高度。 吊扇的扇葉需安裝距離地板最小7英尺，否則可能造成傷害。其實大部份吊扇摩打只有低扭力，如摩打受到阻力，將迅速失去動力，減少傷害。如風葉由輕型材料組成，在高速時受到撞擊將較容易折斷。強力的鋼葉或金屬工業吊扇葉片比木製或塑膠能夠造成傷害，若受到撞擊仍能迅速失去動力。
A typical ceiling fan weighs between 15 and 50 pounds when fully assembled. Solid concret ceiling is essential for installing ceiling fan as two bolt screws will be inserted into concret ceiling to hang the ceiling fan. Major concern with installing a ceiling fan relates to the height of the blades relative to the floor. American law states that no fan can be mounted with its blades closer than seven feet from the floor, otherwise potentially causing injury. Residential ceiling fans are, apparently by design, largely incapable of causing more than minor injury, having low-torque motors that slow down quickly when blocked, and blades composed of light materials that tend to break easily if impacted at speed. More powerful industrial ceiling fans with steel blades proved capable of causing injury and laceration, but still lost energy rapidly once blocked.
Wobbling 搖動
搖動是因風扇葉片的重量不平衡而引起的顫動。這是由於各種因素的影響，包括葉片是翹曲的，葉片被彎曲，沒有被正確安裝，或葉片的不同重量/ 形狀/ 尺寸(這些細微的偏差)。此外，如果葉片具有不同的角度，空氣力學上不相等，垂直反作用力可引起擺動。這些擺動不會是因風扇安裝的方式，或在安裝表面而受影響。
Wobbling is caused by the weight of fan blades being out of balance with each other. This can happen due to a variety of factors, including blades being warped, blade irons being bent, blades or blade irons not being screwed on straight, or blades being different weights or shapes or sizes (minute differences matter). Also, if all the blades do not exert an equal force on the air (because they have different angles, for instance), the vertical reaction forces can cause wobbling. Wobbling is not affected by the way in which the fan is mounted or the mounting surface.
吊扇風扇於操作過程中會產生輕微移動，事實上，它們不是緊固地安裝在天花上，如果是緊固的安裝在天花上，吊扇風扇產生的震動可以另震動天花石屎。
Ceiling fan tend to move during operation due to the fact that they are not generally rigidly mounted- if they were, they could generate excessive ceiling vibration and stress on their Mountings.
吊扇風扇所產生的幾豪米的搖擺是完全可以接受的，並且不會令吊扇風扇會掉下來。
Movement of a couple of centimeters is quite acceptable and does not suggest the fan will fall down.
吊扇風扇安裝在非常牢固的鋼支架與橡膠緩衝或球型接頭，之所以允許自由搖動。
Ceiling fans are mounted very securely on steel brackets with rubber cushioning or with ball-joints to allow free movement.
請注意，所有的吊扇是不一樣的，即使在同一個型號，一些搖動或多或少於其他。
Please note that all ceiling fans are not the same, even in the same model – some may move more or less than others.
普遍人的誤解，吊扇搖動不會導致吊扇墮下。吊扇由固定橫栓及split pins/ R-clips鎖緊，所以搖動不會影響吊扇的安全。至目前為止，並沒有報告因風扇搖擺而從天花板墮下。然而，隨著長時間嚴重的搖動可能會導致燈具或燈罩鬆脫，對風扇下的人構成傷害的風險，也可能被玻璃碎傷害。安裝風扇時緊記，必須跟製造商安裝程序的說明，使用適當的安裝螺絲。同樣重要的是，所有螺絲（特別是鎖緊吊杆的螺絲）必須擰緊，和吊扇燈具和燈罩也必須牢固地連接。
Contrary to popular misconception, wobbling will not cause a ceiling fan to fall. Ceiling fans are secured by clevis pins locked with either split pins or R-clips, so wobbling won’t have an effect on the fan’s security. To date, there are no reports of a fan wobbling itself off the ceiling and falling. However, a severe wobble can cause light fixture shades or covers to gradually loosen over time and potentially fall, posing a risk of injury to anyone under the fan, and also from any resulting broken glass. It is important that, when installing the fan, the installer closely follows the manufacturer’s instructions with regard to using proper mounting screws. It is also important that all screws (especially the set screws which hold twist-on downrods in place) be tight, and any ceiling fan light fixtures are properly assembled with their shades and covers securely attached.
