Abstract: Miniature heat pump refrigeration system (MHPRS) offers the advantages in size and
weight that can realize the effect of coofing under special conditions, such as limited space, limited
carrying weight load. However, its fabrication is complicated, and in general the system efficiency is
low. This paper gives a review of MHPRS based on published literature, and summarizes latest
applications and research progress of miniature compression-type thermodynamic cycles, and
miniature compressors as core components compared with conventional size heat pump refrigeration
systems. The main characteristics of MHPRS as well as the dominating factors influencing their
performance are analyzed and discussed. The miniature compressors have the advantages of high
pressure ratio, simple structure and good sealing, but have the disadvantages of difficulty in
processing, low stability, high noise and others. The vibration and noise of miniature compressor also
need to be paid attention for the individual micro-environment refrigeration. The future trends in
relevant researches, and feasibility of combination with renewable energy, such as solar energy are
proposed
Key words: miniature thermodynamic cycle; miniature compressors; renewable energy
