科学合理的能源规划方案对提高能源利用效率、保障能源供应安全有着重要意义。本文针对某典型用户的负荷特点,提出了一种低碳型冷热电联供(BCHP)系统配置方案,通过全年负荷预测和能耗分析,将该方案与其它方案进行了比较。分析可知,该方案可充分利用低位热能,使深入挖掘烟气余热与土壤源等低位热源成为可能;在夏季将制冷与除湿相结合可提高供热供冷效率,并实现热量回灌,保持地热的冬夏季平衡。同其它方案相比,此方案的供热节能与减排量均在50%以上,同时可降低运行费用,增量投资回收期在1 a左右。该方案的确定为低碳型能源系统的配置以及能源规划的制定提供了新的途径。
Scientific and reasonable energy planning programs are of great importance to improving energy efficiency and ensuring energy supply security. In this paper, according to the load characteristics of a typical user, a scheme of low carbon CCHP system configuration is proposed. Compared with other schemes, this scheme is compared with the annual load forecasting and energy consumption analysis. Analysis shows that this scheme can make full use of low-grade heat energy, making it possible to dig deep waste heat such as flue gas and low-level heat sources such as soil sources. Combining cooling with dehumidification in summer can increase heating and cooling efficiency and achieve thermal recharge and keep geothermal Winter and summer balance. Compared with other schemes, the heat energy saving and emission reduction of this scheme are above 50%, meanwhile, the operating costs can be reduced. The payback period of incremental investment is about 1 year. The program’s determination has provided a new avenue for the configuration of low-carbon energy systems and the formulation of energy plans.
