Optimized peak heat source configuration for secondary network of renewable energy heating system
摘要：
结合地热供热系统的特点，采用能源中心+末端换热站供热模式，中深层地热承担基本热负荷，天然气锅炉承担调峰热负荷。基于费用年值法，建立了以年运行费用和全寿命周期内费用年值最小为目标的模型。以西安市某新区为例，分析了不同调峰热负荷系数下的能耗、初投资及年运行费用。结果表明，最佳调峰热负荷系数为0.25。
Abstract：
Combined with the characteristics of geothermal heating system, adopts a heating mode of energy station plus terminal heat exchange station, with the medium-deep geothermal energy for essential heat load and the natural gas boiler for peak heating load. Based on the annual cost method, develops a model aiming at minimal annual operating cost and annual life cycle cost. Taking a new district in Xian as an example, analyses the energy consumption, initial investment and annual operating costs with different peak heat load factors. The results show that the optimal peak heat load factor is 0.25.
