【摘要】 为了研究制冷剂充注量对直接膨胀式地源热泵性能的影响,进行了不同充注量实验。根据实验数据分析了充注量的变化对系统运行输入功率以及对蒸发压力、冷凝压力和系统性能系数(COP)等的影响,系统运行最佳效率状态确定最佳充注量。研究结果可为直接膨胀式地源热泵的优化运行提供指导。更多还原

【Abstract】 In order to study the effects of refrigerant charge on the performance of Direct Expansion Ground Source Heat Pump,many experiments under different charge were carried out。 Based on the experimental results,the effects of changing the refrigerant charge on the input power of system,condensing pressure,evaporating pressure and coefficient of performance(COP) were analyed。 The optimum Refrigerant Charge was determined by the optimum efficiency。 The conclusion from this study may be guidance of optimizing the the performance of Direct Expansion Ground Source Heat Pump。更多还原
