一种高效双级压缩离心式冷水机组
本技术涉及冷水机组
,尤其涉及一种高效双级压缩离心式冷水机组。
技术介绍
离心式冷水机组有以下几个特点:一、冷量大,运行费用高,对能效要求较高;二、离心式冷水机组体积大,占地面积大,对机组的紧凑性要求较高;三、大型工厂、数据中心等场所,冷水机组是稳定运行的基础,其故障造成的损失较大,所以对机组的稳定性要求较高;四、近年来,环境问题越来越引起人们的注意,使用环保制冷剂也成为大家的共识。目前市场上主要有以下几种离心式冷水机组产品:1、单级压缩机离心式冷水机组;2、开启式离心式冷水机组;3、负压制冷剂(R123)离心式冷水机组;4、磁悬浮离心式冷水机组。以上离心式冷水机组的缺点如下:缺点1:机组1的转速较高,机组运行噪音较大;缺点2:机组2存在轴封漏油问题,且电机产生的热量排至机房内,造成热污染;缺点3:机组3负压机组体积大,占地面积大,且R123不属于环保制冷剂;缺点4:机组4价格高,技术起步阶段,目前国内应用案例较少;缺点5:现在市场上氟冷电机接线柱存在“冷桥”效应,需要对 ...
