In higher load, the CCHP owns obvious saving energy potential. With the decrease of the 领域，而建筑能源需求中的冷、热需求通常随气温 load, the advantage is reduced; and its performance is worse 的变化而变化，因此冷热电联产系统一般为变工况 than traditional systems after the load is low enough. To [3-4] 模式运行。文献 对于冷、热负荷的变化有所研究， improve CCHP all-operation performance, the phase change 但它们关注的主要是设备容量的优化配置。 storage system and the potential storage system are combined 大多数情况下冷热电联产系统处于变工况运行 with CCHP. Through the simulation of some building all-operation heating and cooling demands in winter and 模式，部分负荷下联产系统的性能对联产系统的发 summer, respectively, it is found that the utilization of storage 展至关重要。为此，本 对采用单轴燃气轮机的冷 systems make
