Description

Water mist fire extinguishing system for central air conditioner of mail wheel Technical Field The application relates to the technical field of ship fire control, in particular to a water mist fire extinguishing system of a central air conditioner of a mail wheel. Background The mail wheel air conditioning system operates in high-load, high-humidity and high-salt-fog environment for a long time, and a large number of auxiliary pipelines, cable bridges, fan units and other electromechanical devices are generally arranged in the installation and arrangement space of the air conditioner room serving as a central air conditioner in a centralized manner. In order to cope with the fire risk possibly occurring in the central air conditioner, water mist pipelines and nozzles are mostly arranged in the room of the air conditioner room, and the central air conditioner is protected against fire by forming a water mist coverage area in the air conditioner room. However, due to the compact layout of equipment inside the air conditioner room, the pipelines and cables are densely distributed, and the practical water mist nozzles often face the problem that the effective working space is seriously shielded. The large number of peripheral pipelines obstruct the spray spraying path, so that the water mist is difficult to effectively cover the core part of the central air conditioner, which is easy to cause fire extinguishment success rate to be low when fire actually occurs, and reliable protection of the central air conditioner is difficult to realize.
