吸入管路蓄能器广泛应用于现代蒸汽压缩制冷系统中，以保护压缩机免受液体制冷剂进入吸入口造成的机械损坏。不同类型的压缩机，如往复式、旋转叶片式、离心式和旋转螺杆式压缩机，其处理液体制冷剂的能力各不相同。然而，有一点是肯定的，制冷压缩机的设计仅用于压缩气体，系统的设计和运行应确保只有蒸汽从系统进入压缩机。由于几乎不可能在所有操作条件下完全消除系统蒸发器中的液体溢出，明智的投资是安装一个吸盘，在液体到达压缩机之前将其排出。 蓄能器在尺寸、形状和结构上有很大的不同。在许多情况下，它们设计用于多种功能，例如减温器、泵接收器、低压接收器、油分离器。液体捕集器的设计原理并不复杂。设计的三个基本部分是确定所需的喘振体积、所需的液气分离体积和消除过量累积液体的方法。引用:ASHRAE交易，第81卷，第一部分，新泽西州大西洋城

Suction line accumulators are widely used in modern vapor compression refrigeration systems to protect the compressor from mechanical damage due to liquid refrigerant entering the suction port. Different types of compressors, such as reciprocating, rotary vane, centrifugal, and rotary screw designs vary in their ability to handle liquid refrigerant. One thing is certain, however, refrigeration compressors are designed for compression of gas only, and systems should be so designed and operated that only vapor enters the compressor from the system. Since it is almost impossible to completely eliminate liquid slop-over from the system evaporators under all operating conditions, a wise investment is the installation of a suction trap to remove the liquid before it reaches the compressor.Accumulators vary considerably in size, shape, and construction. In many instances, they are designed for more than one function, e.g., desuperheater, pump receiver, low pressure receiver, oil separator.The fundamentals governing the design of the liquid trap are not complicated. Three basic parts to the design are determination of the required surge volume, the required liquid-vapor separation volume, and the method of eliminating excess accumulated liquid.
