摘    要:根据哈尔滨某制药厂的污水情况,在污水源热泵系统中采用多级淋激式换热器作为污水侧换热器。采用分区参数法将换热器按制冷剂状态分为过热、两相、过冷三区,分别计算了各区的换热温差、传热系数等。分析了结构参数变化对换热器性能的影响,从而合理地设定了管列数、管径和管长,详细设计出三级淋激式换热器的结构。

关 键 词:污水源热泵系统  淋激式换热器  结构参数

Abstract:According to the status of sewage in a pharmaceutical factory in Harbin, uses the multistage spray heat exchanger in the sewage-source heat pump system. Based on the refrigerant state, divides a heat exchanger into three zones with zoned lump method, i.e. superheat, two-phase and subcooling zones, works out the temperature difference and heat transfer coefficients of the three zones. Discusses the influence of structural parameters on the heat exchanger performance in order to get more rational setting of the number of columns, diameter and length of tubes, and designs the three stage spray heat exchanger in detail.
Keywords:sewage-source heat pump system  spray heat exchanger  structural parameter
