In this paper, many methods about simulation analysis and study of air conditioning system ( ACS) for civil aircraft are introduced. The mathematic models of ACS components for civil aircraft are built, and the simula-tion modules of ACS components and cabin/cockpit heat load module are developed. , The simulation model of air conditioning system for some civil aircraft is established, which is verified by examples. ACS ram air flow-rate calculation in flight envelope is predicted by validated simulation model . The ram air energy consumption is evalua-ted by standard algorithm to provide the basis for ACS design optimization. It is of great references for civil aircraft ACS design optimization and airworthiness compliance verification.
