[Introduction] The compressed air energy storage power station lacks corresponding codes as technical support in the design of main power House. There are some controversial and inapplicable provisions in the Code for design of compressed air station, which is difficult to meet the needs of the current large-scale development of compressed air storage power station. The paper aims to solve these critical problems in the implementation of the codes and to find better design schemes for the main power House. [Method] The explosion risks of the air energy storage compressor were analyzed, an economic comparison between the combined power House design and the separate power House design was made, and the storage volume of compressed air in the compressor room was sorted out and summarized. [Result] The results show that the air energy storage compressor has no chemical explosion hazard, and no physical explosion hazard on the premise that the equipment′s quality meets the standard. Combined power House design can save a lot of investment compared with separate power House design. The storage volume of compressed air in the compressor room is smaller than that of the main power House. [Conclusion] From the perspective of process flow, system integration, overall economy, convenient operation and maintenance, combined power House design is recommended for the main power House of a large-scale compressed air energy storage power station. According to the process layout and maintenance operation requirements, large platform structure is also recommended. A class-A fire door can be set up when the compressor power House is adjacent to other rooms, and the door buckets together with other protective measures should be set up.
