摘 要:水质状况不仅对江水源热泵系统的水处理方案、换热器形式的合理选择具有影响,还直接关系到系统的运行效果和使用寿命。研究针对重庆地区嘉陵江和长江的水质变化情况开展了全年逐月测试。结果表明:两江水的pH值、钙镁离子及硫酸根离子变化趋势具有一致性;相较于嘉陵江而言,长江水除铁离子含量和浊度值较高外,其它几种水质指标均低于嘉陵江水。为合理选择水处理系统,对比分析了两江水的各种水质指标与水热泵机组和换热器的允许值,发现在利用嘉陵江水作冷热源时,需采用过滤器或除砂设备着重处理6-9月的浊度,采用电子水处理仪或离子棒水处理仪处理12月、1月和2月的钙镁离子;而对于长江水,需利用过滤器或除砂设备解决全年浊度水平过高问题。The selection of water-treatment program and exchanger of river source heat pump system is directly affected by water quality.In addition,the performance and lifespan of the system are also directly affected by water quality.The research on water quality of Yangtze River and Jialing River in Chongqing is done by the annual monthly testing.The results indicated that Yangtze River has lower value of water quality than Jialing River except Iron and pH,but has the same change trend as Jialing River on pH,Ca2+and Mg2+,SO42-.At the same time,base on the data,the comparative analysis of the two rivers' water quality and the value allowed by air-conditioning unit and heat exchanger is done.And the analysis indicated two pivotal points.One is that the turbidity should be removed by filter or grit equipment from June to September.The other is that Ca2+and Mg2+ should be removed by electronic or ion bar water treatment equipment in January,February and December when Jialing River is used as cooling and heating source.Another is when Yangtze River is used as cooling and heating source,we just only take more attention on the turbidity all of the year.
