This paper provides a literature review on ejectors and their applications in refrigeration. A number of studies are grouped and discussed in several topics, i.e. background and theory of ejector and jet refrigeration cycle, performance characteristics, working fluid and improvement of jet refrigerator. Moreover, other applications of an ejector in other types of refrigeration system are also described.

Ejectors: applications in refrigeration technology

A complete review of working fluids of absorption cycles is presented. Absorption cycles contain absorption heat pumps, absorption chillers and absorption transformers. Working fluids are divided into five series according to different absorbents.

A review of working fluids of absorption cycles

Absorption heating technologies: A review and perspective

Application of absorption heat transformer to recover waste heat from a synthetic rubber plant

Performance analysis of the single-stage absorption heat transformer using a new working pair composed of ionic liquid and water

Performance analysis of an absorption heat transformer with different working fluid combinations

Study on a new ejection-absorption heat transformer

A two-stage heat transformer with H2O/LiBr for the first stage and 2,2,2-trifluoroethanol(TFE)/N-methy1-2-pyrrolidone (NMP) for the second stage

The utility model provides a jet-absorption-type heating apparatus, relating to a waste heat recovery and renewable energy utilization apparatus which can change lower grade energy into middle grade heat energy The jet-absorption-type heating apparatus is characterized in that a jet composed of a nozzle, a mixing chamber and a diffuser is arranged at a traditional absorption type heating apparatus Compared with the traditional single stage absorption type heating apparatus, the utility model has the advantages of effective output temperature improvement under the same heat source temperature condition, and obvious system performance; compared with the double stage or double effect absorption type heating apparatus, the utility model has the advantages of simpler structure, convenient maintenance and operation, less equipment and low manufacture cost
