    The efficiency of the combined solar collector in the gravity mode in the southern orientation
    (Lviv Polytechnic Publishing House, 2015) Shapoval, Stepan; Vengryn, Iryna; Lviv Polytechnic National University
    In the article we investigated the efficiency of combined heating system in the southern orientation on the territory of Ukraine and the change in the intensity of solar radiation during the experiment. Also it’s investigated the quantity of heat flux that has entered the plane of solar collector in natural conditions during the experiment.

    The potential of solar energy in Ukraine
    (Lviv Polytechnic Publishing House, 2015) Shapoval, Stepan; Lviv Polytechnic National University
    In this paper the analysis of potential cumulative, direct, and diffuse solar radiation on the territory of Ukraine during to the period of one year and during the heating season is presented. It is shown that there is a change in these variables in Ukraine received empirical functional relationship to calculate the solar energy. The incoming solar energy in Ukraine has been analyzed according to its geographical position (i.e. latitudes). These research results may be used in the design and choice of location solar heating in Ukraine.

    Experimental studies of combined heat supply system in the flow mode during the summer period for Lviv
    (Lviv Polytechnic Publishing House, 2015) Pona, Ostap; Gulay, Bohdan; Shapoval, Stepan; Lviv Polytechnic National University
    Experimental model of a combined solar collector (SC) in the flow mode is effective in seasonal (summer) period of application. The article presents the analysis of thermal energy, accumulated by solar heat supply system (SST), and energy that were received on the plane of the solar collector in the course of the experiment.
