Journal/Article Review 3 – HEAT TRANSFER & CHANGE OF PHASE
Title of Journal/Article:
Effect of phase change material on the heat transfer rate of different
building materials

Brief Summary:
Energy conservation and efficiency is a highly concern among researchers
and industrialists. In this fast-changing world where there is a continuous increase
in population, thus also increase in the number of infrastructure and buildings, the
need to prioritize energy efficiency is vital. In addition, reducing heat transfer through
the building materials will conserve energy. That is why in this article, the
researchers particularly determine the effects of having phase changing materials
(PCM) on building materials on the rate of heat transfer. PCM are widely known as
latent heat storage. Meaning, they can absorb latent heat to make thermal comfort
because PCMs has the ability to store and release large amounts of latent heat and
this characteristic is ideal for the constructions of modern buildings. They used
paraffin as the PCM and tested it alongside with different conventional building
materials to investigate the rate of heat transfer. And they have found out that there
is a significant difference or advantage on achieving steady state conditions using
the PCM alongside with the different conventional building materials. Which means
that PCMs such as paraffin is effective to be used in construction to reduce heat
transfer thus promotes energy efficiency.
Reaction/Impact:
I have learned in our thermodynamic lesson about the phase change as well
as the latent heat and how does this work or all about this concept. However, I didn’t
know at first that there is an actual phase change materials that is significantly used
in our industrial buildings meaning, they are everywhere around us and we are
benefiting from them. That is why upon searching about the journal articles regarding
this topic, this research article really caught my interest. Because prior from reading
this I just only know about insulators that are used between walls to reduce heat, but
I didn’t realize that those some videos I am watching in youtube or facebook
something similar about this, are actually PCMs. And is significantly used on today’s
world. This research and my realization are the real life example of this concept, and
I will remember this not only from the examples given and because of the formulas.
But because of its significance and the fact that it is already around me.
