    Sammanfattning : The Phase change materials (PCM) have the ability to absorb and release heat as the temperature changes from high to low temperature and vice versa. The use of phase change materials has increased in the construction sector due to the established environmental requirements and the various application benefits, especially in the thermal comfort of building applications and construction of sustainable infrastructure around the world (Berardi and Gallardo, 2019).

    Master-uppsats, KTH/Energiteknik

    Författare :JiaCheng Lin; HaoRan Teng; [2019]
    Nyckelord :Phase Change Material; Latent Thermal Energy Storage; Temperature-history; Sugar Alcohols; Supercooling; Duration of crystallization; Crystallization; Solidification; Fasändringsmaterial; Latent Termisk Energilagring; T-history; Sockeralkoholer; Underkylning; Varaktighet av kristallisering; Kristallisering; Stelning;

    Sammanfattning : Utilizing Phase Change Materials (PCM) for Latent Thermal Energy Storage (LTES) applications have previously been extensively researched as a measure to reduce greenhouse gas emissions from energy consumption. In order to make use of the waste heat from industrial processes for LTES purposes, a new demand emerged for PCMs capable of phase change in mid-temperature ranges of 100 °C - 200 °C. LÄS MER

    Nyckelord :PCM; Phase change materials; Thermal Storage;

    Sammanfattning : All energy, wind, water, biofuel and fossil fuel besides nuclear- and tide power originates from the sun. It’s very hard to take full advantage of the huge amount of energy hitting the earth each day from the sun. The suns highest radiation appears often when the energy need reaches its lowest. LÄS MER
