Annotated Summary on HVAC system. (Seekers - Don)


In the article “The Rising Demand for Air Conditioners”, Team (2020) claims that the use of air conditioning is increasing and thus, driving the global electricity demand by 2050. Southeast Asia is already using about 60 percent of its electricity for air-con alone. The need of air conditioning has been increasing even till today due to the increased ambient temperature from climate change. Climate change had cause countries like France and Australia to experience temperature as high as 45.9 degree Celsius and 49.5 degree Celsius in 2019. Heatwaves are becoming more common and it is affecting everyone in this planet, Earth. Heat can prove lethal, especially to vulnerable group such as infants, the sick and elderly. A simulation was conducted by the Centre for Climate Research Singapore, the result shows that Singapore can expect to face temperatures of 40 degree Celsius as early as 2045. With the rise of global temperatures, more people are buying air conditioning units today. The air conditioning units create an environment where one will feel much more comfortable when the sweltering heat is replaced with cold air. With the increasing frequency of air conditioning usage, it leads to a higher power consumption. However, an increasing rate of air conditioning use can also increase the rate of carbon dioxide that is released into the atmosphere. A leak from a faulty air conditioning unit can also release refrigerant (hydrofluorocarbons) into the atmosphere thus trapping heat in the Ozone layer and worsening global warming (climate change). The writer also mentions that by educating consumers on efficient usage and easy to read manuals can also reduce carbon footprints and power wastage.

    Dear Donovan,

    For an annotated summary, the reference should be placed all the way at the top of the document. The annotated summary also needs to include your view on the article and how it relates to your research topic.

    Regards,

    Dear Donovan,

    Your annotated summary is missing your views on the topic and the link between your findings and your report. Otherwise i had a great time reading your summary.

    Regards,

Self Introduction (edited 300920)

  Subject: Self-introduction Dear Professor Blackstone,   My name is Donovan Chan and I am writing this to introduce myself as a student attending your effective communication module. I am a year 1 engineering student studying Sustainable Infrastructure Engineer Building Services in Singapore Institute of Technology (SIT).   I graduated from Ngee Ann Polytechnic in 2018 with a diploma in Aerospace Technology. From young, I had always been interested in engineering and on how things work, particularly on cars and aircraft. In my free time, I would usually do my research in the powetrain system of a car. To be specific, the engine. During my Polytechnic days, I managed to gain hands-on experience during my internship at one of the Aerospace companies. I got to open up and learn the insides of a fuel pump from an aircraft. I find it very intriguing and this is the reason why I still chose the world of engineering.   My weakness is in verbal communication. At times, I wo...

Article summary: Porous Asphalt Is King of the Road (Draft 1)

In the article “Porous Asphalt Is King of the Road”, PaveGreen (n.d.) claims that porous asphalt is the best pavement surface. The world sees a need to fight pollution and are doing all they could to slow down the rate of global warming as our climate is changing faster than predicted. Porous asphalt pavement is one way to improve safety, reduce erosion and mitigate water pollution. What makes porous asphalt different is, under the pavement is a “recharge bed” built of stones with spaces between them allowing water to flow through. Rainwater sinks through the pavement into the recharge bed and filtered out into the earth. This concept is also used on superhighways for safety purposes. It sharpens the visibility during rainstorms. During winter, it helps to reduce the need for de-icing. The writer also mentions that adopting the use of porous asphalt is a cheap solution for going green considering that the cost is similar to typical asphalt.  Reference: PaveGreen. (n.d.). Porous Asp...
