重庆市某小型能源站冷热源优化设计
Optimization of cold and heat source for a small energy station in Chongqing
摘要：
以重庆市某小型能源站设计为例，利用TRNSYS模拟软件模拟了建筑群的逐时冷热负荷，得到了能源站的逐时负荷和负荷率分布，并分析了建筑群的负荷特征。根据负荷率的分布，以全年运行费用及全寿命周期费用为目标函数，对冷热源方案进行了优化设计。结果表明，对于该能源站，采用以离心机+直燃机为冷热源的方案全寿命周期费用较低。

Abstract：
Simulates the hourly load of a small energy station in Chongqing by the TRNSYS software, obtains the hourly load and load ratio, and analyses the load characteristics of the buildings. According to the load ratio distribution, performs the optimal design for the energy station by the objective function of annual operating cost and life cycle cost (LCC). The result shows that the LCC of the centrifugal liquid chiller and direct-fired absorption chiller is less.
