根据最不利用户资用压头选择循环水泵的传统设计方法存在缺点,这种传统设计方法,调节阀至少要节流掉30%的能量,造成能源的极大浪费。本文作者应用HFSNET软件,分别对多种不同的分布式变频系统进行模拟计算和可及性分析,得出最优的供热输配系统设计方法———用户混水变频泵与沿途加压变频泵和主循环变频泵相结合的方法,可节能75%。本论文研究的供热输配系统设计方法是用于指导系统设计和运行的有效手段,应用到工程实践中将会取得巨大的经济效益和社会效益。
According to the most unfavorable user-funded choice of recirculating water pump pressure head shortcomings of traditional design methods, this traditional design method, the throttle valve to cut off at least 30% of the energy, resulting in a tremendous waste of energy. The author of this paper applies HFSNET software to simulate and analyze the different distributed frequency conversion systems respectively to get the optimal design method of heat transfer and distribution system --- user mixing water frequency conversion pump and frequency conversion frequency conversion Pump and the main loop frequency pump combination of methods, can save 75%. The heat transfer system design method studied in this paper is an effective means to guide the design and operation of the system. It will achieve huge economic and social benefits when applied to engineering practice.
