| Abstract: |
| Objective To investigate the scheme of the air handling system which is suitable for the large climatic environmental test facility. Methods The scheme of the air cycling system, the fresh air system and the air compensation system was discussed based on the functions of the air handling system in large climatic environmental test laboratory. The working process as well as the advantages and disadvantages of each system were analyzed. An optimized integrated air handling system scheme was put forward based on the analysis. Results The air cycling system adopting the ducts in series could better ensure the limit temperature and humidity as well as the uniformity indices of the facility. The integration of the air cycling system with the air compensation system was better than the two independent systems, and was feasible. Conclusion The scheme of the air handling system put forward in this paper was suitable for the large climatic environmental facility. |
