Micro refrigeration systems for personal cooling: a review

The development of MEMS makes the micromation and light weight of process machine possible. Compared with the size of traditional refrigeration systems, the size of micro ones can reduce to below onesixtieths. Micro refrigeration systems can be widely used for personal cooling in special environment. Presents the research findings and progress of micro refrigeration systems at home and abroad, points out the current main problems and puts forward some suggestions for the future researches.
