ENERGY OPTIMISATION OF THE MODULAR GREENHOUSE FOR THE NORTH ADRIATIC CLIMATIC CONDITIONS

Due to the increase in price of fossil fuels and a greater ecological awareness, in today's world there is a need to explore the possibilities of using alternative energy sources, primarily solar energy. However, due to the intermittence of solar radiation, as well as the fact that its daily intensity oscillation is incompatible with the daily oscillation of energy consumption, it is necessary to construct a system for energy accumulation with the aim of using optimally solar energy. It is necessary to store that part of irradiated solar energy which exceeds the heating requirements during the day in a thermal storage energy unit so that later this energy can be used when there is no solar radiation (night). In that way a significant saving of heat and therefore fuel too is achieved. Accumulation of solar energy is particularly suitable for greenhouses because during the day heat gains from solar radiation significantly exceed heat losses [1], [2]. This paper analyses the heating requirements of the solar greenhouse and compares it with conventional greenhouse requirements. An analysis of heat consumption has been carried out for the North Adriatic climatic conditions, more precisely for the geographic latitude of 45.3°.
