Smart farm where the treated water is used as boiler supplement water nutrient solution water and cooling water

摘要

The present invention provides a smart farm comprising: an inflow water storage unit (410); a water treating unit (420) which produces treated water through RO treatment of inflow water stored in the inflow water storage unit (410); and a treated water storage unit (430) which stores the treated water produced in the water treating unit (420). The smart farm comprises: a greenhouse (100) which receives a nutrient solution of a nutrient solution storage unit (400); and a boiler (200) which is connected to a makeup water supply unit (300) and heats the greenhouse (100). The treated water stored in the treated water storage unit (430) is selectively supplied to the nutrient solution storage unit (400) or to the makeup water supply unit (300). The treated water in the treated water storage unit (430) is connected to a heat medium supply pipe of the boiler (200) to cool the heat medium supply pipe. Accordingly, the smart farm can use treated water as boiler makeup water, nutrient solution supply water and cooling water.
