| Abstract: |
| Objective To select the refrigerants and secondary-refrigerants suitable for the large climatic environmental test facility. Methods The selection principle of the refrigerants and secondary-refrigerants was proposed based on the analysis of characteristics of cooling systems in climatic environmental test facility. The properties of common refrigerants and secondary-refrigerants were comparatively analyzed, and the optimization of the refrigerants scheme was conducted considering the environmental friendliness, the refrigeration inner-circulating characteristics, the requirements of the cycle air system and the makeup air system. Results R507 and R23 were selected as the refrigerants for the high- and low-temperature sections of the cascade system, respectively, AS-6 was selected as the medium- and high-temperature secondary-refrigerant, while AST-30 was selected as the low-temperature secondary-refrigerant. Conclusion The scheme of the refrigerants proposed in this paper was applicable to the large climatic environmental facility. |
