中文摘要: 为了对医院的供能分布式系统进行优化，提出了由2个江水源热泵与原分布式系统组成的复合系统模型，将其应用于上海某医院，利用TRNSYS软件分析对比了燃气轮机有无回热和江水源热泵性能系数（COP）变化下优化系统与原系统的年总成本。研究结果表明：随着江水源热泵COP的增大，年总成本逐渐减小；燃气轮机无回热时的年总成本低于有回热时的年总成本；江水源热泵处于制热端时分布式复合联供系统的年总成本最优，年总成本要远低于原系统方案。
Abstract:In order to optimize the distributed system of hospital energy supply,this paper proposes a composite system model composed of two river water source heat pumps and the original distributed system,and applies it to a hospital in Shanghai.The annual total cost of the optimized system and the original system with or without gas turbine heat recovery and the river source heat pump COP change is analyzed and compared by using TRNSYS.The research results show that:with the increase of the COP of the river water source heat pump,the annual total cost gradually decreases;the annual total cost of the gas turbine without recuperation is lower than the annual total cost with reheat.The annual total cost of the compound distributed system is optimized,and its annual total cost is much lower than the original system plan.
