An Annotated Summary

Dincer, I., & Abu-Rayash, A. (2020). District Cooling System. ScienceDirect. https://www.sciencedirect.com/topics/engineering/district-cooling-system

 

In this article, Dincer and Abu-Rayash (2020) fixate on the topic of the district cooling system. According to the authors, district cooling systems generate chilled water for multiple households as a “deliverable commodity exactly like water and electricity.” A centralized production containing multiple chillers are located underground to generate chilled water. Water pumps will then transport the chilled water to various households through a network of insulated pipes. The chilled water can either be transported directly to the building’s fan coils or interchanged with the building’s heat exchangers. This system removes the need for users to have personal air-conditioners and chillers, thus resulting in substantial energy and cost savings. The authors also mentioned that buildings employing the district cooling system have to be in close proximity to each other. Consequently, this system is ideal for “dense cities or institutions with numerous buildings such as university campuses.”

 

This article is important for our report as there are useful statistics on the benefits of the district cooling system. For example, this system “offers highly efficient processes leading up to more than 40% of energy efficiency improvements and 20% lifecycle cost savings.” Dincer and Abu-Rayash also mentioned that this system is environmentally friendly as it utilizes water instead of refrigerants and decreases greenhouse gas (GHG) emissions. The district cooling system was also reported to reduce power consumption by 50% when compared to conventional cooling systems. The authors further stated that “district cooling systems present a reliable cooling source, as they are unpretentious by peak load demands and grid interruptions,” making them the ideal choice to replace conventional cooling systems in dense residential estates.

A Descriptive Reflection in the Form of a Formal Letter

-
Dear Professor Blackstone,   My name is Clement Ten, from your effective communication class (T3). I am writing this letter in hopes that you will get to know me a little better. I graduated from Temasek Polytechnic with a diploma in clean energy engineering. Though I am currently pursuing my degree in sustainable infrastructure engineering, about two years ago, I had ambitions to study criminology due to my fascinations with problem-solving and analytical work. However, through much deliberation and wise counsel from friends and family, I thought it best to tread on a more familiar path.   One of the strengths that I have in communication is my ability to adapt to different communication styles according to my audience. As I was working in a café-bar as a barista two years ago, I had to converse with customers from different walks of life. During the day, the café-bar served cakes and tarts to casual coffee-loving customers; in the evening, we served main courses and wines to...

The Importance of Communication Skills for Engineers

-
“While all engineers should have good communication skills, global engineers face additional challenges, making effective communication an imperative.” Debra Kraft, Careers Content Writer, Demand Media (2016)   Due to language barriers, global engineers are confronted with an additional challenge of communicating effectively across different cultures. This problem is harder than it seems due to the fact that languages are usually intertwined with culture. For the global engineer to communicate  effectively,  he has to go the extra mile to learn the language's unique sentence structures, grammar rules and even cultural slangs that are commonly used in its region. A simple example would be the difference in the way english is spoken in Singapore as compared to the original english language. Singaporeans' usage of "lah" and "lorh" have often confused other english speaking nationalities. This problem would be further compounded when the global engineer is requ...
