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%。
The energy consumption of different modes of air conditioning and domestic hot water load characteristics, system configuration and condensing heat recovery system in a hospital were simulated and compared respectively from the aspects of economy, energy conservation and environment. The results show that the primary energy saving rates of partial condensing heat recovery and total heat condensing heat recovery system are 5.6% and 13.2% respectively compared with those of conventional systems. The operating costs of each cooling season are respectively 129,900 yuan and 299,000 yuan , And the static investment payback period is 3.81a and 1a, respectively; and the reduction rate of carbon emission is 5.7% and 13.2% respectively.
