As it is known, if the consumption rate continues in the same way, oil
will be exhausted after 50-60 years and coal will be exhausted after 100-150
years. For this reason, many studies are carried out to minimize energy
consumption and use of renewable energy resources. In this study, it is aimed
to increase the efficiency of heating and cooling systems as a result of the
application of PCM to the building walls. It was used to decrease the heating
and cooling load in a test room which was formed by evaluating isothermal
behavior of PCM and high volumetric storage properties. The results of the
experiment showed that the melting point of the phase-changing substance in the
building and the melting point contributed positively to the energy saving as a
result of thermal energy storage. When selecting PCM, it is necessary to
determine the most suitable melting point, thermal property and encapsulation
method. It is performed for the phase change substance in microencapsulated PCM
capsule to obtain a more suitable environment for the transfer of heat. In this study, microencapsulated PCM was
used. When the test chamber was empty and the PCM agent was used, comparisons
showed that micro-capsulated PCM has been determined that it contributes about
5-10% cooling load in the summer and 10-20% of heating load in in winter
period. According to this study, the obtained values and graphs were found to
be consistent with the literature. As a result, the application of PCM to the
building walls will help us to save on fossil fuel and electricity consumption,
domestic resources will be used more efficiently and reduce dependence on
foreign sources. However, investments will be reduced and environmental savings
will be achieved by decreasing emissions.
