家用冰箱制冷机组多以毛细管作为节流装置,这一特点使得用计算方法确定其最佳致冷剂充注量复杂化。现在已籍助机组调试和模拟试验方法将其确定下来。原有的理论分析表明,系统容积,特别是蒸发器容积对充注量有主要影响。 Domestic refrigerator refrigeration units to use more capillaries as a throttling device, which makes the use of computational methods to determine the optimal refrigerant charge complexity. It has now been aided by crew commissioning and simulation test methods to determine it. The original theoretical analysis shows that the system volume, especially the evaporator volume has a major impact on the charge.
