  螺杆式冷水机组选购技巧:螺杆式冷水机组简介

  1、螺杆式冷水机选用冷水机组时,应注意名义工况的条件。

  ①冷水出水温度和流量;

  ②冷却水的进水温度、流量以及污垢系数。

  2、选用冷水机组时,应注意该型号机组的正常工作范围,主要是主电机的电流限值是名义工况下的轴功率的电流值。

  3、在设计选用中应注意:在名义工况流量下,冷水的出口温度不应超过15℃,风冷机组室外干球温度不应超过43℃。若必须超过上述范围时,应了解压缩机的使用范围是否允许,所配主电机的功率是否足够。

  4、冷水机组的选用应根据冷负荷及用途来考虑。对于低负荷运转工况时间较长的制冷系统,宜选用多机头活塞式压缩机组或螺杆式压缩机组,便于调节和节能。

  5、选用螺杆式冷水机组时,优先考虑性能系数值较高的机组。根据资料统计,一般冷水机组全年在100%负荷下运行时间约占总运行时间的1/4以下。同时,在设计选用时应考虑冷水机组负荷的调节范围。多机头螺杆式冷水机组部分负荷性能优良,可根据实际情况选用。

  以上为大家介绍了螺杆式冷水机组选购技巧,在我们以后购买螺杆式冷水机组的话,上面介绍的这些技巧能成为大家不错的参考对象,相信大家肯定能购买到适合自己用的螺杆式冷水机组,给我们带来很好的制冷效果。
