空气源热泵热水机组系统仿真的研究

Study of the Digital Simulation for Air Source Heat Pump Unit

建立了空气源热泵热水机组的系统仿真流程,给出了机组四个主要部件的稳态仿真数学模型,进行变工况稳态工作性能预测,同时给出了换热器中的换热关联式模型。稳态仿真结果与21组实验数据相比,机组运行特性与制热特性均得到准确模拟,验证了所建模型的可靠性。

A general steady - state simulation model was presented for predicting the performance of air source heat pump unit under variable operation conditions. Mathematic models of four main components in the unit were set up. Three- zone parameter model was developed for the heat - exchangers. The good agreement between simulation and experimental results indicated that the model could be successfully used in performance predicting of the air source heat pump.
