The project is constructed by the Hot Spring County Housing and Construction Bureau, and adopts the heating method of middle and deep hot spring hot water + centrifugal heat pump + electric boiler + heat storage tank. The hot water temperature of the underground 60℃ hot spring is 40℃ after heat exchange. 4 sets of heat pump units can provide 67℃ hot water and 3 sets of 65.7MW open type electric boilers can provide 72℃ water supply to the heat network. There are also three 3,179.0m³ open-type heat storage tanks, utilizing peak and valley electricity to store heat. The project has built a new energy station to provide heating for 95.0 million square meters of existing heat users in the county, and the heating effect meets the requirements of energy saving, environmental protection and low carbon after one heating period.
