摘要
压缩式冷水机组是化工装置冷水系统的核心设备。介绍不同类型冷凝器、蒸发器、膨胀节流装置结构特点;分析对比制冷剂特性,螺杆式冷水机组和离心式冷水机组的冷量范围、负荷调节、COP值(名义工况性能系数)。
Compression-type water chiller is the core equipment of chilling water system in chemical plant. This paper describes the structure characteristics of the different types of condensers,evaporators,expansion throttle unit; analyzes and compares the characteristic of refrigerant and the cooling capacity range of screw type water chiller and centrifugal water chiller,load regulation,COP value(nominal working coefficient of performance).
