PURPOSE: A public bath utilizing natural energy and renewable energy is provided to prevent the waste of energy by blocking the inflow of outer air current and the outflow of inner hot air because a building is installed as a closed structure. CONSTITUTION: A public bath utilizing natural energy and renewable energy comprises a building or a land, a water recycling system, an air current circulating system, a solar energy producing system, a wastewater recycling system, and an energy storage. The water recycling system is installed in the building or on the land and recycles water by settling, circulating, and purifying rainwater or waste water. The air current circulating system circulates air current in and out of the building or the land, and utilizes the produced energy or stored energy. The solar energy producing system produces heat produced by sunlight or hot water heated by the heat. The wastewater recycling system collects the hot heat of the waste water by circulating the used hot water. The energy storage stores and uses the heat and hot water producing in the solar energy producing system, cold air, and ice(35). |
