5.1 Summary of findings
After doing Experiment 1,2 and 3, we have concluded that the dehumidifier is unable to remove moisture from the air and instead adds to the relative humidity of its surroundings. This could be due to several reasons as explained in 4.2 and 4.4.
5.2 Practical Applications
The automatic dehumidifier is extremely convenient to Singapore’s environment, where work comes before well-being. Fundamentally, it will serve its purpose as a dehumidifier and reduce the excessive amount of humidity in the air. However, the dehumidifier can go a step further by switching on and off automatically according to the fluctuating humidity to ensure that people who are preoccupied will not have to do it themselves. Moreover, people often do not realise what is the suitable range of humidity, which is around 45% - 50%, and they go about their daily lives experiencing a level of relative humidity that is potentially harmful. The automatic dehumidifier can assist them in acknowledging the excessively high level of humidity and furthermore switching on so that it is able to decrease the humidity level back to an acceptable range.
The automatic dehumidifier is also economically beneficial. Many times people leave their dehumidifiers running for hours on end for various reason, be it they forgot about the dehumidifier or they were too wrapped up in their work to switch it off. The advantage of the automatic dehumidifier is that once the relative humidity has been been brought down to an apt percentage, instead of running on until someone remembers to switch it off, the dehumidifier will turn off on its own. This way, it will not consume more electricity than needed and help reduce the bills of numerous households.
Moreover, many people use air conditioners instead of dehumidifiers when they feel too uncomfortable due to high humidity levels even if they are experiencing cold weathers. Air conditioners draw a lot of power and in some cases, where the weather might be already be cold, there may not be any need for the cool air dispensed by the air conditioning unit. Therefore, much of the power drawn in by the air conditioner goes to waste. In addition to that, air conditioners are manufactured by Chlorofluorocarbon (CFC), which upon escaping travel 30 miles above the earth to the ozone layer and then proceed to destroy the ozone layer (Ozone Layer Protection, 2010). This way, air conditioners are a great contributor to global warming as they release CFCs every time they are in use. Contrary to this method, people can use the dehumidifier to reduce the high humidity levels in their homes as an alternative to air conditioners and save not only power but also the earth. The dehumidifier does not release any CFCs, in fact the silica gel it uses is non-toxic to humans, pets and the environment (Yudisky), which makes it more environmentally friendly than air conditioners.
5.3 Areas for further study
This is only the first step towards the development of more user-friendly dehumidifiers. If the dehumidifier is improved upon to fix up the areas it is lacking in we can manage to build a dehumidifier that will open a gate way for many more alterations and innovations of different kinds of dehumidifiers, such as automatic ones.
Also, little studies have been done on humidity, some of them being (Dai, A., 2006) (Willet, 2007). Therefore, further research can be done on humidity, how it affects us and the work and school climate that we live in and experience on a daily basis so as to better understand its characteristics. This way more in depth knowledge can be acquired about humidity and based on that, better and more efficient dehumidifiers can be made. Not only that, through the extensive research that could be done,everyday appliances can be adapted to better sustain humidity to provide more comfort to its users.
We have also discovered the many functionalities of silica gel, such as its ability to absorb water and then be warmed to be rid of the water in it. Moreover, silica gel is nearly harmless, which is why it is found in multiple food products. (HowStuffWorks, 2000) This is proof of the fact the silica gel is extremely useful as a desiccant and through more thorough research, its various characteristics could be put to other uses for the betterment of people’s lives.
