Problems solved by technology

However, it can be seen from heat transfer theory that the higher the temperature of the heating circulating water, the greater the heating temperature difference, and the more heat energy will be transported. The low temperature and small temperature difference transportation of the second network not only increases the initial investment of pipelines, but also increases the circulating water pump. power consumption

Abstract

The invention relates to a distributed heating system. The distributed heating system comprises: a secondary network hot water circulation module, a user-side hot water circulation module, a first heating pipeline, a second heating pipeline and a return water The output end of the secondary network hot water circulation module is connected to the input end of the user-side hot water circulation module through the first heating pipeline and the second heating pipeline. The input end of the water circulation module is connected with the output end of the return water pipeline, and the output end of the user-side hot water circulation module is connected with the input end of the return water pipeline. The distributed heating system provided by the present invention adopts the secondary network hot water circulation module to reduce the initial construction investment and system operation cost of the project through the same water supply and return pipes in most heating areas and a distributed control system, and can effectively solve the heating system. The phenomenon of water conservancy imbalance can realize the unconditional grid-connected operation of multiple heat sources.

Description

technical field [0001] The invention relates to the field of urban heating, in particular to a distributed heating system. Background technique [0002] At present, the central heat supply in cities and towns mainly adopts the indirect heat supply form of central heat supply with combined heat and power. After obtaining heat from the heat source, the first-network heating water supply heats the second-network water through the heat exchange station, and the heated second-network water is transported to the heat user, and the indoor heating is carried out through the terminal heat dissipation equipment. In this mode, the temperature difference of the first network heating is about 40°C, and the temperature difference of the second network is 10-15°C. It is the most common heating mode in the heating industry at present, and it reduces the phenomenon of uneven heating and cooling of heat users to a certain extent. . However, it can be known from heat transfer theory that the...
