New research shows that a very large number of modern ceiling fan designs are not all that unique.
According to the study, published in the journal PloS One, some ceiling fans can actually be quite similar.
The researchers say this suggests that ceiling fans are very similar to many of the designs of earlier in history, which can be attributed to the way in which they were designed.
“What we see in the study is that modern designs are actually quite similar to older designs,” Dr. Hyeon Kim, a co-author of the study and a senior lecturer at the University of Melbourne, told BBC News.
“We think they are very simple, they are relatively inexpensive, they can be found in a wide variety of products and they can easily be adapted to a variety of applications.”
In order to find the modern designs that could be considered the most unique, the researchers looked at the history of ceiling fans.
They were able to find designs from around the world, including the early days of ceiling fan design, which was based around simple cylindrical shapes that had a diameter of about three inches (7 centimeters).
The researchers then compared these designs to those found in museums and antique shops.
In order for these to be considered unique, they needed to be able to withstand the temperatures required to keep them from freezing.
“Modern designs that we have in the museum are probably comparable to the designs we have on the market today,” Dr Kim said.
“It’s hard to imagine that some of these designs would survive the long winter months.”
But the modern ceiling designs that are used in modern applications have different cooling requirements.
“Modern designs are designed for use in a cold climate and the cooling requirement is very different to the cooling requirements for the past,” Dr Kaeun Kim, the lead author of the paper, told ABC News.
In a world where most people are exposed to air temperatures between -5 and 15 degrees Celsius (minus 30 degrees Fahrenheit), the amount of heat produced in the air by modern designs would be much higher than what is needed for cold climates.
This may explain why some modern designs have cooling requirements that are lower than those for the ancient era.
“It’s a very simple thing to explain,” Dr Joon Hyeok Lee, an expert in modern materials science and engineering at the university, told Reuters.
“You can find a lot of similarities between modern and ancient designs.
But there are many differences.
Modern designs have the benefit of being able to be used in a very hot environment and these cooling requirements are very different.”
In fact, the team found that some modern ceiling design are not even capable of being used in the cold climate.
“The cooling requirements of the modern design is very similar for cold and hot climates,” Dr Lee said.
Dr Kim and his colleagues have been using computer models to predict the cooling needs of modern designs and have found that the current generation of modern design can be made to cool in just one day, if it can be kept inside the room for just one hour.
Dr Lee told BBC that modern design designs are a better choice than the more simple designs that were available in the past.
“We are seeing new designs coming out that are very much in line with the ancient designs, but these new designs are being created with the knowledge that they are not designed for the cold conditions,” he said.
“The design that we are seeing today is very close to the ancient design and the designers have taken a lot more care to make sure that the design does not need to be in a constant state of freezing, because it’s not going to be as efficient as it could be.”
The team has been using the computer models that were developed to predict that the modern room fans will require about a third of the cooling required for the classical era, the study found.
The researchers also found that even though many of these modern designs were not built to last for the long cold season, they do have the capability to last a bit longer.
The study shows that in order to be unique, modern designs must be able not only to survive the cold season but also to last longer.
“I would say that for this generation of ceiling designs, we’re seeing the ability to survive winter,” Dr Hyeong Kim said, referring to the modern designers.
“I think that it’s possible for some of the design to last as long as the classical style.”
But while this study shows the potential of modern designer designs for longevity, it also shows the challenges of adapting these designs for a variety the different uses of these design.
“Our studies show that we need to make certain adaptations in order for the modern era to continue,” Dr Kelly said.
