GB 50084-2017 第4.2.6条
| | For spaces complying with Article 4.2.5 of this code, an automatic sprinkler system with early suppression fast response (ESFR) sprinklers may also be used where the ambient temperature permits. In hotels, areas with large clear heights such as atriums and lobbies may use this system in place of a deluge system where conditions are met. |
