高层供暖系统加压方式与技术经济分析

探讨了住宅小区同时存在多层建筑与高层建筑的高层供暖系统加压方式。以高层建筑采用高位水箱定压系统为研究对象,理论分析了初期注水及定压补水时水泵扬程远高于系统循环时水泵扬程。结合工程实例,对设置兼用于补水、加压泵的方案与分别设置补水泵及加压泵的方案进行了经济性分析,后者的经济性较优。

Pressurization Mode of Heating System for High-rise Buildings and Its Techno-economic Analysis

The pressurization mode of heating system for high-rise buildings in the residential area where multi-story and high-rise buildings coexist is discussed.Taking a high-rise building using pressuri- zation system by elevated expansion tank as research object,the theoretical analysis shows that the lift of water pump during initial water injection and pressurization by make-up water is much higher than that during circulation of the system.Combined with an engineering example,the economic analysis is made on t...
