【摘要】 以宁波地区的某办公建筑作为冷热电三联供系统的用能对象,研究了内燃机容量和吸收式制冷机容量的组合对系统经济性的影响,给出了容量配置范围参考表,同时提出了适用于该地区办公建筑三联供系统的容量配置比。结果表明:办公建筑三联供的回收期在5.6～9.3年之间,内燃机大容量和吸收式制冷小容量的配置经济性最差,内燃机容量和吸收式制冷容量的组合应该在合适的范围内,宁波地区办公建筑吸收式制冷容量与内燃机容量的容量配置比建议值为1.32,按该比例配置容量时随着容量同时增大,回收期较短且变化不大,但年收益和系统初始投资都有较大幅度增长,投资者还需根据自己投资能力和收益需求确定容量规模。更多还原

【Abstract】 An CCHP model was established to study the influence of configuration of internal combustion engine generator capacity and absorption chiller capacity on the economic performance,by selecting an office building in Ningbo China as the energy consumer.The list of recommended configuration range was obtained,and he configuration ratio of generator capacity and absorption chiller capacity was proposed for CCHP system of Ningbo office buildings.It has been found that the payback period will be between 5.6 years and 9.3 years.Configuration of large generator capacity and small absorption chiller capacity will have the worst economic performance.The configuration of capacity should be appropriate.The recommended capacity configuration ratio for Ningbo office CCHP system should be 1.32,and the payback period will remain short by this ratio when configuration varies,while the annual profit and the investment cost will have dramatic growth.Therefore,investors should also consider their investment abilities along with their return on investment to determine appropriate size of capacity by configuration ratio.更多还原
