摘 要工程概况：该机房制冷系统为四管制系统，即冷却水供/回水管、冷冻水供/回水管系统。经冷水机组制冷后的 7℃的冷冻水通过冷冻水供水管到达分水器，再通过分水器分别送往旅馆的各个区域，经过空调机组后的 12℃的冷冻水回水经集水器再由冷冻水回水管返回冷水机组，通过冷水机组中的蒸发器与制冷剂换热实现降温过程。从冷水机组出来的 37℃的冷却水经冷却水供水管到达冷却塔，经冷却塔冷却后降温后再返回冷水机组冷却制冷剂，如此循环往复。考虑到系统的稳定安全高效地运行，系统中配备补水系统，软化水系统，全程水处理系统等附属系统。关键词: 住宅、制冷机房、设计目 录第1章 原始资料 ··································1第2章 方案设计······························22。1设计方案·····························22。2 定压方式····························22.3 管材的选择与防腐····························2第3章 制冷循环系统热力计算···························3第4章 冷水机组的选择···························5 第 5 章 管径的 确 定 ···························6 第 6 章 水泵的选择···························7 5.1冷冻水泵的选择······························7 5。2冷却水泵的选择······························75。3补水泵的选择······························7第7章 其它设备的选型···························87。1冷却塔的选择······························97.2分水器与集水器的选择························97。3软化水箱及补水箱······························97.4其它附件······························9设计小结································10主要参考文献··························...
