摘要:
直接式污水源热泵是用污水作冷热源直接进入热泵机组蒸发器、冷凝器进行换热的系统形式，相对于使用中间换热器的间接式污水源热泵来说，减少了换热损失，但其污垢的生长严重影响了机组的性能．以西安某污水处理厂直接式污水源热泵为研究对象，该系统以城镇二级出水为冷热源，在机组换热器清理维护后对其进行了供暖、供冷两个工况的连续测试．结果表明由于流动形式和温度条件的不同，蒸发器和冷凝器内污垢的生长规律有所不同，作者测试计算得到了二者传热系数随着污垢生长的衰减特性，拟合出了污垢的生长预测模型，可为污水源热泵系统的设计和应用提供参考．
Abstract:
Direct sewage source heat pump system is a form which let sewage goes directly into its condenser and evaporator. It can usually reduce energy loss relative to indirect form which use an intermediate heat exchanger, but fouling influence the energy efficiency of the system a lot. Authors of this article take a direct sewage source heat pump in Xi’an as the research object, the system uses municipal secondary effluent as its cold and heat sources. After cleaning and maintaining the heat exchangers of the system, the consequent tests have been finished under the cooling and heating operating conditions of the system. The result shows that the growth rhythm of fouling in condenser and evaporator is different because of the difference of flow mode and temperature conditions. The authors test and calculate the attenuation characteristics of the heat transfer coefficient of the two heat exchangers, establish and fit the growth prediction model of the fouling, compare and analyze the difference of fouling characteristics in condenser and evaporator, which can be a reference in the design and application of sewage source heat pump systems.
