摘要

针对小区集中供暖扩容改造问题,提出3种方案。方案1:增加4台燃气热水锅炉;方案2:增加3台燃气热水锅炉和1台烟气换热器;方案3:增加2台燃气热水锅炉和1台烟气全热回收型吸收式热泵。给出主要设备的技术参数、投资、运行成本,对3种方案进行经济性比较,得出方案3最优。
        In view of the problems of central heating capacity expansion and reconstruction in residential areas,three schemes are proposed. The scheme1: add 4 gas hot water boilers. The scheme 2: add 3 gas hot water boilers and 1 flue gas heat exchanger.The scheme 3: add 2 gas hot water boilers and 1 flue gas full heat recovery-type absorption heat pump. The technical parameters,investment and operating cost of the main equipment are given. The economy of the three schemes is compared,and it is concluded that the scheme 3 is optimal.
