氨水蓄能土壤源热泵集成系统工作过程的模拟研究

Simulation of an integrated ammonia-water solution energy storage and soil source heat pump system

提出了以浅层土壤为热源/汇的氨水蓄能热泵集成系统,建立了系统工作过程动态数学模型。以长江流域某一办公建筑为例,对该系统夏季空调工况和冬季供暖工况进行了数值模拟。与以空气为热源/汇的氨水蓄能热泵集成系统进行了比较,结果显示以土壤为热源/汇的系统工作性能优于以空气为热源/汇的系统。

Presents the integrated system using ammonia-water solution as working fluid and the heat pump system using shallow soil as the heat source and sink, and develops a mathematic model of its dynamic working process. Taking an office building located in the Yangtse River basin as an example, numerically simulates the cooling mode in summer and heating mode in winter of the system. Compares the simulation results with those of the integrated system using air as the heat source and sink, and concludes that the performance of the integrated system using soil as heat source and sink is better than one using air as heat source and sink.
