摘　　要：针对集装箱建筑供暖、生活热水需求,以热负荷自给自足为目标,搭建离网式PV/T集热器联合空气源热泵供热系统(简称联合供热系统)。以单个集装箱房为例,限定联合供热系统发电量不满足耗电量时间,采用Hooke-Jeeves算法,以最小费用年值为目标,对联合供热系统配置进行优化。优化后联合供热系统发电量不满足耗电量的时间37.9 h,可基本实现热负荷自给自足。优化后,主要设备容量保持不变或有不同程度降低,各项系统性能指标合理。与优化前相比,费用年值减少12.2%。In view of the heating and domestic hot water demand of container buildings,with the goal of selfsufficiency in heat load,an offgrid PV/T collector combined with airsource heat pump heating system(referred to as combined heating system)was built.Taking a single container house as an example,the power generation of the combined heating system is limited to not meet the power consumption time,and the HookeJeeves algorithm is used to optimize the configuration of the combined heating system with the minimum annual value as the goal.After the optimization,the combined heating system does not meet the power consumption time of 37.9 h,which can basically achieve selfsufficiency in heat load.After the optimization,the capacity of the main devices remains unchanged or decreases to varying degrees,and the various performance indicators of the system are reasonable.Compared to before the optimization,the annual cost decreases by 12.2%.
