Abstract

The invention relates to an urban large thermal capacity water circulating system utilizing a renewable energy source, belonging to the technical field of region energy comprehensive utilization. The invention aims at enabling cold and heat in a region to naturally balance and reducing mechanical conversion heat to be the minimum so as to directly supply the cold, the heat and domestic water for region buildings, fully utilize the renewable energy source and improve the energy supply efficiency and energy consumption safety. The urban large thermal capacity water circulating system comprises a water feeding and discharging subsystem including a primary water treatment function, a large-thermal-capacity water circulating pipe net subsystem, a user side subsystem including a middle-high water treatment function, and an auxiliary thermal source subsystem. The invention provides a direct heat supply and cold supply energy source conversion and utilization manner, realizes an idea of supplying water with different qualities for a user side, provides a user with domestic hot water, middle water and direct drinking water, and realizes functions of an urban heat supply pipe net, an urban cold supply pipe net and an urban water supply pipe net through a set of pipe net; therefore, a conventional energy source is saved, an urban municipal pipe net system is simplified, the pipe net construction cost and the operation management cost are reduced, and the system can be applied to urban region energy source comprehensive utilization and combined energy supply optimal design.

Description

technical field [0001] The invention relates to an urban large heat capacity water ring system, which belongs to the technical field of regional energy comprehensive utilization. Background technique [0002] At present, the research on joint energy supply system at home and abroad mainly focuses on the combined heat and power system of conventional energy and the combined heat, power and cooling system. Judging from the development at home and abroad, these systems all use fossil energy or are mainly based on fossil energy. With the advancement of technology, the efficiency of traditional fossil energy systems has been significantly improved, and the cost of improving efficiency in the later period is very high. Moreover, with the acceleration of my country's urbanization process, the supply of fossil energy such as petroleum and coal is in short supply. It is a major trend for the urban energy system to be supplemented by renewable energy or transformed into a renewable e...
