分析了重庆市CBD总部经济区采用冷热电联供和江水源热泵复合供能系统进行区域供能的自然条件,结合项目动态冷热负荷和系统冷热源机组配置情况,根据机组经济成本最低优先开启、机组高负荷率运行和吸收式机组尽量避免补燃等原则,确定了机组的优先开启顺序和冷热源系统的运行策略,得出了复合系统的能耗。分析了能源价格在一定幅度(90%~130%)内变化时冷热量价格盈亏平衡点的变化规律及其敏感性。
Based on the analysis of the natural conditions of district heating in CHUECC using the combined heat and power (CHP) supply and the water-source heat pump complex energy supply system, combined with the project’s dynamic cooling and heating load and the system configuration of cold and heat sources, Priority to open, the unit load operation and absorption units try to avoid burns and other principles, to determine the priority of the unit to open the order and operating system of cold and heat source strategy, obtained composite system energy consumption. The change regularity and sensitivity of the hot and cold price break-even point when the energy price changes within a certain range (90% ~ 130%) are analyzed.
