  4. 2. Heat Transfer Enhancement of Latent Thermal Energy Storage in Rectangular Components

    Author : Amir Abdi; Viktoria Martin; Justin NingWei Chiu; Mohammed Farid; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Abstract : Latent Thermal Energy Storage (LTES) is an interesting choice to storethermal energy in a sustainable energy system. The primary benefit of LTESis the relatively high latent heat of fusion of the materials, known as PhaseChange Materials (PCM), used in such a system as the storage medium. READ MORE

  6. 4. Laminar-flow Liquid-to-air Heat Exchangers - Energy-efficient Display Cabinet Applications

    Author : Caroline Haglund Stignor; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-efficiency; indirect cooling; display cabinet; pressure drop; heat transfer; flat-tube heat exchanger; cooling coil; laminar;

    Abstract : Provisions are stored and displayed in supermarkets and grocery stores, at a temperature lower than the ambient, in display cabinets, which are responsible for a significant amount of the energy use in this sector. During the 1990s, major changes in the regulations governing the use of synthetic refrigerants took place in Sweden. READ MORE

  7. 5. Optimal Pin Fin Heat Exchanger Surface

    Author : Hamid Nabati; Jafar Mahmoudi; Mohsen Assadi; Mälardalens högskola; []
