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

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.
