The paper analyses the innovative internal blinds, which allow to use the solar energy, received through a window for a heating, more efficiently and to ensure a greater air velocity due to the convection. Blinds are constructed that one side is covered with material, which absorbs the solar energy and the other side is reflective. Thus, there is an ability to control an amount of absorbed solar radiation and air supply temperature between the window and the blinds. In addition, the construction of the air to provide locating elements. The elements for air deflection are additionally foreseen in the construction. Due to the natural circulation cold air falls between the blinds and the window, then warms up and rises to the top. The paper presents an empirical and theoretical assessment of an operation of the blinds. In addition, the analysis of the experimental researches of an air flow intensity and a dependency of temperature increase from external (climatic) conditions is performed.
