CO2 refrigeration is in demand all over the world for a variety of issues, including: use of lower GWP refrigerants following the environmental regulations that will direct the operators to adhere to the corporate sustainability norms, and the fact that some western countries have brought their preferred CO2 refrigeration over the conventional HFC systems. From an environmental point o, traditional hydro- fluorocarbon (HFC) systems used in majority of the refrigeration systems. Numerous lower-GWP alternatives are present that can be used over the full spectrum of GWP ratings, but CO2 as refrigerant is often considered as a sustainable alternative to the future as it suffices the current and known future regulation requirements. As a result, refrigeration unit manufacturers are devising methods to perfect the CO2 refrigeration technology to support the use of this environmental friendly alternative. The paper discusses the review of some research work that uses CO2 as refrigerant, various methods discussed in this work on use of Co2 as refrigerant. The paper discusses the development of CO2 refrigeration system using the ejector in the refrigeration circuit. The paper deals with the modeling theoretical and structural analysis of the components of ejector. The components of the system have being modeled using unigraphix Nx, and the analysis has being done using Ansys work bench-16.0
