Abstract: Miniature heat pump refrigeration system（MHPRS） offers the advantages in size and weight that can realize the effect of cooling 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.
