▎ 摘　　要

NOVELTY - High-efficiency energy-saving heating system has a cold water tank (200) whose water outlet is connected to a water inlet of a graphene solar system (100) for storing cold water. A water inlet of a hot water tank (300) is connected to a water outlet of the graphene solar system for storing hot water. A water inlet of an electric heating system (500) is connected to a water outlet of an air energy water heater system (400) for evaporating the hot water into steam. A water outlet of a surface treatment production line is connected to a water inlet of the hot water tank for electroplating process. A power supply output end of a solar photovoltaic assembly is connected to a power supply input end of the air energy water heater system for providing power supply. USE - The system is useful in electroplating industry. ADVANTAGE - The system reduces the investment in the electroplating industry and improves the return rate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the High-efficiency energy-saving heating system in electroplating industry.
