与传统的往复式压缩机相比，直线压缩机没有曲柄机构。当线性压缩机用于蒸汽压缩制冷（VCR）系统时，这允许更高的效率、无油操作、更低的成本和更小的尺寸。通常，线性压缩机由线性马达（连接到活塞）和悬挂弹簧组成，以共振频率操作。本文对制冷系统用直线压缩机进行了综述。讨论了用于家用制冷和电子冷却（微型VCR系统）的线性压缩机的不同设计和建模。介绍了直线压缩机的主要特性，包括电机类型、压缩机损耗、活塞传感和控制、活塞漂移和共振。与线性压缩机相关的挑战也进行了讨论，以提供一个全面的审查技术的研究和发展的未来。
Linear compressor has no crank mechanism compared with conventional reciprocating compressor. This allows higher efficiency, oil-free operation, lower cost and smaller size when linear compressors are used for vapour compression refrigeration (VCR) system. Typically, a linear compressor consists of a linear motor (connected to a piston) and suspension springs, operated at resonant frequency. This paper presents a review of linear compressors for refrigeration system. Different designs and modelling of linear compressors for both domestic refrigeration and electronics cooling (miniature VCR system) are discussed. Key characteristics of linear compressor are also described, including motor type, compressor loss, piston sensing and control, piston drift and resonance. The challenges associated with the linear compressors are also discussed to provide a comprehensive review of the technology for research and development in future.
