System and method for regulating and controlling temperature of concrete dam

The invention discloses a system and method for regulating and controlling the temperature of a concrete dam. The system comprises a temperature compensation source, a regulating and controlling medium, a medium replacing device, a reversible multi-connected output circulating pipeline, a temperature partition secondary regulating device, a flow regulating device and a control system. According tothe system and method for regulating and controlling the temperature of the concrete dam, through structural and functional design, corresponding components and control system development are adopted, multiple (more than two) regulation and control media with different temperatures and different flows can be provided by one set of device and output to a regulation and control pipe network arranged in the concrete dam, the flow and temperature of the media in each group of circulating pipelines are automatically adjusted in real time, and the flow direction can be automatically changed at anytime to meet the temperatu
