从压缩机制造商的角度来看，吸入蓄能器好坏参半。如果使用得当，它们可以提供非常大程度的保护，防止因暂时失去足够的液体控制而发生液体制冷剂溢流。我怀疑在过去几年里，没有比压缩机制造商更好的蓄能器销售人员了。但蓄能器并不是解决所有系统制冷剂问题的灵丹妙药。在现场安装的系统上，选择程序充其量只是一个有点随意的过程，可能并不总能达到预期的结果。如果我们要明智地讨论蓄能器的应用，我们首先需要清楚地了解，为了提供合理程度的保护，我们必须对压缩机暴露在液体制冷剂中设置哪些限制。压缩机用于泵送制冷剂蒸汽，而不是液体吸入阀和排出阀，如果受到泵送蒸汽中的液滴的影响，其应力可能会远远超过其预期设计极限。 但更令人担忧的是，返回压缩机的液体对润滑的影响蓄能器在其设计概念中似乎是一个简单的装置——仅仅是一个贮存器，用于收集溢出的制冷剂，并以压缩机能够承受的速率将其送入压缩机。但在实际操作中，这并不是那么简单。引用:ASHRAE交易，第81卷，第一部分，新泽西州大西洋城

From the viewpoint of a compressor manufacturer, suction accumulators are a mixed blessing. Applied properly, they can provide a very substantial degree of protection against those periods when liquid refrigerant flooding occurs due to a temporary loss of adequate liquid control. I suspect there have been no better salesmen for accumulators than compressor manufacturers for the past several years. But an accumulator ·is not a magic cure-all for every system refrigerant problem. On a field installed system, the selection procedure at best is a somewhat haphazard process which may not always achieve its desired results.If we are to discuss accumulator application intelligently, we need first to have a clear understanding of just what limitations we must place on compressor exposure to liquid refrigerant in order to provide a reasonable degree of protection. A compressor is built to pump refrigerant vapor, not liquid suction and discharge valves can be stressed far beyond their intended design limits if subjected to liquid droplets in the vapor being pumped. But of far more concern is the effect of liquid return to the compressor on lubricationAn accumulator appears to be a simple device in its design concept - merely a reservoir to trap flooding refrigerant and feed it to the compressor at a rate which the compressor can tolerate. But in actual practice, it is not so simple.
