| 摘 要： | 城市污水处理厂高耗能限制其运转及发展,基于能耗分析提出了污水处理厂资源能源综合利用技术路线。再生水源热泵回收污水厂外排水低温余热,将其提升后满足污泥高温消化等需热工艺;被吸取热量后低温水用于建筑制冷,形成再生水源热泵冷热联供系统。研究了冷热联供系统工况,以系统联合负荷收益性能系数为指标,提出夏季工况下联供系统最优制冷量即热泵蒸发侧吸热量,分析了蒸发温度对制冷效率影响。整体能流分析表明,再生水源热泵冷热联供系统可降低城市污水厂污泥厌氧消化处理工艺和建筑制冷供暖能耗,夏季和冬季工况节能率分别可达30%、40%。

| Abstract: | From the analysis on energy consumption,a reclaimed water source heat pump based combined heating and cooling system was proposed to use the energy in available resources from wastewater treatment plants.In the present sysytem,a reclaimed water source heat pump is used to absorb the heat of wastewater from the plant to meet the heating need in the thermophilic anaerobic digestion process.Then the wastewater with lower temperature is applied to cool the plant buildings in summer.The effect of the evaporating... |
