摘要
对某医院空调及生活热水负荷特性、系统方案配置、冷凝热回收系统不同方式的能耗进行模拟计算,分别从经济性、节能性及环境性进行对比分析。结果表明:相对于常规系统,部分冷凝热回收和全热冷凝热回收系统的一次能源节能率分别为5.6%和13.2%;每个供冷季节约的运行费用分别为12.99万元和29.9万元,静态投资回收期分别为3.81a和1a;碳排放量减少率分别为5.7%和13.2%。
Studies the load characteristics,the system scheme configuration and the methods of condensation heat recovery system of air conditioning and domestic hot water in a hospital building,dynamically simulates and calculates the energy consumption of conventional system,part-load condensation heat recovery system and full-load condensation heat recovery system using TRNSYS software,and compares and analyses the aspects of economic,energy conservation and environmental benefits respectively.The results show that,comparing with conventional system,the primary energy conservation rate of part-load condensation heat recovery and full-load condensation heat recovery systems is 5.6% and 13.2% respectively,and the running expense saved in each cooling period reaches up to 129 900 and 299 000 Yuan respectively,static investment payback period is 3.81 years and one year respectively,and the carbon emission reduction rate is up to 5.7% and 13.2% in each cooling period.
