초록

In order to design a standing column well (SCW) for a sustainable groundwater curtain system for greenhouse heating, we conducted parameter sensitivity tests. These tests simulated the outlet temperature changes of the SCW in a groundwater recirculating greenhouse cultivation system. Our modeling considered ground thermal conductivity and hydrogeological conditions. Specifically, we examined several factors, including SCW length, enhanced thermal conductivity of the ground, and groundwater circulation rate. The simulation results indicated that there was not a significant difference in the heat exchange rate based on the characteristics of enhanced thermal conductivity. However, we anticipate a substantial difference in the case of varying SCW lengths. Therefore, we conclude that the simulation results are primarily influenced by conductive heat exchange values, as the circulating water remains at a constant groundwater level.
