【摘要】 随着社会的发展和工业的进步，能源和环境危机已成为全世界亟待解决的问题。蒸汽作为能源，广泛应用于各行各业当中，蒸汽凝结水回收利用得到关注。以蒸汽为能源的区域供冷供热系统中，凝结水作为生活热水的回收方式，既回收了水资源同时也回收了热量，符合环保和节能的要求。 首先，讨论了凝结水的两种利用方式：返回热源的方式和就地利用的方式，分析了两种方式的适用范围和条件。 其次，针对以蒸汽为能源的区域供冷供热系统，分析了夏季蒸汽溴化锂机组凝结水的产生量和水温情况，冬季汽水换热器的凝结水量和水温情况，凝结水的水质符合生活热水的使用要求，在此基础上分析了生活热水的水量和使用规律，以及凝结水用于区域热水供应系统的技术问题。 最后，以台州东方太阳城的回收实例，对凝结水用于热水供应的夏季、冬季和全年工况地进行了经济和环境效益分析。更多还原

【Abstract】 Energy and environment conjunctures are problems that need to be solved imminently along with the progress of society and industry. The steam is used in all kinds of way as energy source, The people pay more attention to the ways of condensate recovery now. The steam condensate are recoveried and utilized as domestic hot water in district heating and cooling system with steam, which recovery the water source and heat as well, it is according with the environmental protection and energy conservation.First of all, discuss the two methods ways of condensate utilization: one way is to return to heat source, another is to utilize on the spot. Analyze the applicability and condition of two ways.Secondly, for district heating and cooling system with steam, analysis the quantity and parameter of condensate produced by steam-driven lithium-bromide absorption-type refigerating machine in summer; analysis the quantity and parameter of condensate produced by steam-water type heat exchanger in winter at the same time. Quality of condensate is according with the standard of domestic hot water. Research the quantity and regulation of domestic hot water, research the technical problem in condensate used to district domestic hot water system.Finally, take TaiZhou tai yang city for a example, analysis the economical and environmental benefit when condensate is recovried as domestic hot water in different seasons.更多还原
