TY - JOUR TI - Dynamic modeling of а heating system using geothermal energy and storage tank AU - Milanović Predrag D AU - Ećim Olivera Đ AU - Jelić Miloš B AU - Tomić Vojislav G JN - Thermal Science PY - 2012 VL - 16 IS - 3 SP - 947 EP - 953 PT - Article AB - This paper analyzes a greenhouse heating system using geothermal energy and storage tank and the possibility of utilization of insufficient amount of heat from geothermal sources during the periods with low outside air temperatures. Crucial for these analyses is modelling of the necessary yearly energy requirements for greenhouse heating. The results of these analyses enable calculation of an appropriate storage tank capacity so that the energy efficiency of greenhouse heating system with geothermal energy could be significantly improved.
