Review on performance assessment of phase change materials in buildings for thermal management through passive approach
مروری بر ارزیابی عملکرد مواد تغییر فاز در ساختمانها برای مدیریت حرارتی از طریق رویکرد غیرفعال-2020 Latent heat energy storage (LHES) systems using phase change materials (PCMs) are well known for its
excellent thermal energy storage and release during melting and solidifications respectively. PCMs can
be efficiently deployed in applications where significant temperature difference exists in the system
for intermittent thermal energy storage. Several research contributions has been made on integrating
PCMs in buildings for thermal management, as it enhances building thermal inertia, reduces maximum
heat flux, shifts peak energy demand, reduces temperature fluctuations of air, etc., owing to its isothermal
behavior and high energy storage density during phase change. Results of several research articles reveal
that incorporation of PCM in buildings could significantly improve indoor comfort conditions and reduce
energy demand of Heating ventilation and air conditioning (HVAC) systems, provided appropriate PCM
selection, encapsulation methods, location deployed etc. This review paper is devoted to elucidate various
facts attributing PCM integration in buildings for thermal management through passive approach.
The facts includes performance of PCMs in buildings in terms of heat gain reduction, temperature attenuation,
peak energy demand shifting and energy saving potential, encapsulation deployed, are discussed
and presented in order to expedite the interpretation for future researchers, who took their research work
in the field of building thermal energy management. Keywords: Phase change material | Passive approach | Thermal energy management | PCM Encapsulation | Buildings |
