冷热电三联供系统研究（5）：磁悬浮离心式冷水机组的应用
Research of combined cooling heating and power systems (5): The application of centrifugal magnetic suspension water chillers
摘要：
提出了冷热电三联供（CCHP）系统的一种新的设计方法，将集中设置在能源站中的普通离心式冷水机组采用磁悬浮离心式冷水机组替代，并分散设置在园区多个制冷站内，室外冷热水管网按供暖负荷或部分冷负荷设计。工程实例的经济分析结果表明：CCHP系统的初投资和运行费用降低，多项经济指标均高于国家有关部门CCHP系统的规定，经济效益明显。
Abstract：
Puts forward a new design method of CCHP system, which replaces the conventional centrifugal water chillers grouped on the energy stations by the centrifugal magnetic suspension water chillers dispersed on multiple refrigerating stations in the garden district and designs the outdoor hot and cold water pipe network based on the heating load or part of the cooling load. Project economic analysis shows that the CCHP system reduces the initial investment and operating costs and a number of economic indicators are higher than the requirements on CCHP systems stipulated by the relevant national authorities, and the economic benefit is obvious.
