| Abstract: |
| The development of machinery manufacturing and heat recovery technologies has resulted in the development and adoption of environment-friendly reverse Brayton cycle air refrigeration systems. This study introduces the principle of the reverse Brayton cycle and describes the composition, performance, advantages and disadvantages, and applications of seven types of systems, i.e. regenerative cycle, two-stage compression cycle, two-stage expansion cycle, cascade cycle, positive and negative pressure cycles, open and closed loop cycles, and mixed working fluid cycle. Three regenerative schemes (non-regenerative, first-stage regenerative, and two-stage regenerative), positive and negative pressure cycles, and open and closed loop cycles were compared. The optimization methods and advantages and disadvantages of the expander, heat exchanger, and dehumidification devices as well as their development status, are summarized. Finally, the key technologies and future research directions of reverse Brayton cycle air refrigeration systems are discussed. |
