    Heat pumps in subarctic areas: current status and benefits of use in Iceland 
    Atlason, Reynir Smari; Oddsson, Gudmundur V.; Unnthorsson, Runar (Springer Nature, 2017-09-07)
    Heat pumps use the temperature difference between inside and outside areas to modify a refrigerant, either for heating or cooling. Doing so can lower the need for external heating energy for a household to some extent. The eventual impact depends on ...

    Implicit Equation for Photovoltaic Module Temperature and Efficiency via Heat Transfer Computational Model 
    Hassanian, Reza; Riedel, Morris; Helgadottir, Asdis; Yeganeh, Nashmin; Unnthorsson, Runar (MDPI AG, 2022-02-21)
    This paper evaluates the photovoltaic (PV) module operating temperature’s relation to efficiency via a numerical heat transfer model. The literature reports that higher PV module operating temperatures impact PV module efficiency. There are dozens of ...

    Mesh Twisting Technique for Swirl Induced Laminar Flow Used to Determine a Desired Blade Shape 
    Helgadottir, Asdis; Lalot, Sylvain; Beaubert, Francois; Pálsson, Halldór (MDPI AG, 2018-10-10)
    Swirling flow has been shown to increase heat transfer in heat exchangers. However, producing swirl while not presenting a severe pressure drop can be a challenge. In this paper, a desired shape of guidance blades for laminar swirl flow is determined ...

    A Review in Context to Wind Effect on NOCT Model for Photovoltaic Panel 
    Hassanian, Reza; Riedel, Morris; Yeganeh, Nashmin (Crimson Publishers, 2022-02-23)
    This study aims to consider the Nominal Operating Cell Temperature (NOCT) model for the photovoltaic (PV) module by adding the wind effect via experiment equation. The resulting model presents a linear wind convection heat transfer equation; the PV ...
