Abstract

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.
