In the past several decades, many literatures have emerged on the topic of phase change material and latent heat storage techniques used in building. Accordingly, it is essential to review previous work to know about phase change material application in building better. This article presents a review on phase change material application situations in building, and several aspects are discussed: phase change material major applications in building, phase change material application areas, phase change material application types, phase change material thermal-physical properties, and phase change material application effects. The results of this research show that phase change material application areas are mainly concentrated into four parts of north latitude from 25°to 60°and south latitude from 25°to 40°. No matter in which region, the use of paraffin is the broadest (the maximum use frequency is up to 87.5%). For organic phase change material, the melting temperature and the heat of fusion vary from 19°C to 29°C and from 120 kJ/kg to 280 kJ/kg, respectively. The best phase change material application effect found is a reduction of 4.2°C for air temperature in room. This study has important and directive significance for the practical application of phase change material in building.

“…Charakterystyka termiczna MFZ zależy od szybkości akumulacji i oddawania ciepła, stanu skupienia oraz zakresu wahań temperatury. Niemniej jednak, współczynnik tłumienia obliczany w zmodyfikowany sposób był wykorzystywany do oceny efektywności zastosowania MFZ w przegrodach transparentnych [9] oraz pełnych [10].…”

Celem artykułu jest wyznaczenie stabilności termicznej komponentu izolacyjnego modyfikowanego warstwą MFZ. Analiza została przeprowadzona w stanie niestacjonarnym na podstawie rozkładu temperatury w przekroju ściany. Zaprezentowane zostały wyniki obliczeń przeprowadzonych dla dwóch wprowadzonych przez autorów, zmodyfikowanych współczynników tłumienia (ZWT i ZWWT), pozwalających w pełni określić efekt zastosowania warstwy MFZ na stabilizację termiczną przegrody zewnętrznej. Współczynniki określono na podstawie analiz symulacyjnych w Polskich warunkach klimatycznych. Porównanie wyników uzyskanych dla przegrody referencyjnej oraz modyfikowanej warstwą MFZ pokazuje różnice w wartościach ZWT od kilku do kilkunastu procent zależności od analizowanego dnia wybranego okresu czasu.Słowa kluczowe: dynamika cieplna, symulacja komputerowa, ściana zewnętrzna, sezon ogrzewczy, budynek zero-energetyczny

“…For instance, the paraffin based PCM with PCT of 23-26°C did not work in summer in Greece because the lowest temperature was higher than the PCT of PCM [33]. The daily OAT data of Adelaide obtained from the BOM were analysed in order to examine whether the OAT swings between average IAT which is candidate PCT of a PCM for passive and active system in building application.…”

The selection of melting temperature of phase change materials (PCMs) is crucial part of PCM applications in building sector in order to achieve better thermal performance. This study examines various temperatures in Adelaide local climate such as conditioned indoor air temperature and outdoor dry/web bulb air temperature in order to find suitable melting temperature of PCM for passive and active application. According to the conditioned indoor temperature from ten houses in Adelaide, indoor air temperature is maintained between 15°C and 32°C with 22-23°C as an average. Average outdoor dry and web bulb air temperature is less than 18°C and 15°C, respectively. The temperature analysis demonstrates that the PCM with melting temperature around 22°C is assumed to be suitable for passive and free cooling system of residential buildings in Adelaide. On the other hand, the PCM for passive and free heating system is assumed not to work well during most of the day in winter because the outdoor air temperature during the winter lies under the thermal comfort range. Furthermore, the PCM thermal storage unit coupled with evaporative cooling system (EVAP-CS) is expected to increase energy efficiency of building by using outdoor cooled air during the summer night comparing to conventional vapour compression air conditioning system.
