开式原生污水源热泵系统取水运行特性分析

高效的城市污水取水技术是原生污水源热泵系统可靠运行的前提。针对现有相关技术的不足,提出了开式集成污水取水技术。通过定义网眼阻塞系数、污物密度、截面系数等重要参数,建立了表征其取水特性的数学模型,并提出了临界运行工况的参数条件,考察了各临界运行参数及不同旋转周期下网眼阻塞系数等的变化规律。

Operational Analysis of Open Untreated Sewage Source Heat Pump System

The effective sewage intake technology is prerequisite for the untreated sewage source heat pump system to run steadily. In terms of the insufficiency of current sewage intake technologies, an open sewage intake integration technology is proposed. The mathematical model and the distinguish basis of critical state are established for the sewage intake characteristic by defining some important operating parameters, such as the blocking coefficient, the contamination density and the section coefficient. Furthermore, the change rule of each critical operation parameter is observed along with the various initial parameters. The result can provide the theoretical basis to design the open intake integration technology.
