Description

Technical Field

[0002] Central heating refers to a heating method that provides heat energy for multiple buildings or units in a region through a central heating system. Compared with individual household heating, central heating has some characteristics and advantages. Central heating plays an important role in urban construction and development. By sharing heat sources within a region, central heating improves the energy utilization efficiency. Common central heating heat sources include boiler houses, heating plants, combined heat and power generation, etc. Through centralized heating, energy can be utilized more efficiently, energy waste can be reduced, and carbon emissions can be lowered; the central heating system can concentrate combustion boiler facilities at dedicated heating sites, effectively controlling the waste gas and emissions generated by combustion, thereby reducing the risk of air pollution and indoor pollution. Compared with decentralized heating, central heating has less impact on the environment and human health; the central heating system is operated and managed by a heating company or management agency, and the heating equipment and pipe networks are maintained and repaired uniformly. This can ensure the normal operation of the heating equipment and pipelines, and promptly handle faults and maintenance requirements; through the establishment of a perfect heating pipe network and heat substation, the central heating system can achieve balanced regulation of heating load, improving the stability and reliability of heating. Even in cold seasons or peak hours, the heating system can continuously and stably provide heat energy for users; central heating can reduce heating costs through large-scale operation and shared heat sources. The heating company can purchase fuel and maintain equipment more effectively, thereby achieving cost savings, and can provide more competitive heat energy prices through intensive operation.

[0003] However, there are also some challenges and problems in central heating, such as heat loss, pipe network leakage, heat distribution, and damage to pipelines by external forces. Therefore, it is necessary to improve the existing pipelines through reasonable design and improvement of some existing pipelines. Content of the Utility Model
