Transmission Electricity Consumption of Heating System and Building Energy Saving

In order to corporately perform the task of energy-saving renovation of building, this paper discusses energy saving of the hot-water heating system. Base on the current situation of district heating supply system, we study on the electricity consumption of constant pressure and circulation modes to enhance the hot-water heating system efficiency and reduce transmission energy consumption. Through theoretical computation and the actual operation effect, the electricity consumption of various modes are compared and analyzed to forecast heating system energy consumption. In order to corporately perform the task of energy-saving renovation of building and explore optimal energy-efficient heating system means. The electricity consumption of various circulating modes of boiler building heating system and thermal station heating system is compared quantitatively. Correct results are gotten through economic analysis of the system's energy-saving renovation. Proved variable flowrate adjust of the heating system shows that the effect of energy saving is satisfactory and variable frequency technique of pump can save the energy efficiently. It is suitable for renovation of the district heating supply system and provides effective methods and useful experience.
