Description

Technical Field

[0001] The utility model patent relates to the technical field of ventilation duct pressure regulation, and mainly relates to a pressure regulation device for a ship cabin air-conditioning ventilation duct. Background Art

[0002] When a ship sails in various sea areas, the meteorological conditions are complex and the climate is changeable. In order to enable crew members and passengers to have a comfortable living and working environment, air-conditioning technology can be used to create a suitable artificial climate in the cabin and improve the environment. The air-conditioning ventilation in the ship cabin adopts a pressure return air design. Fresh air for air-conditioning is supplied to the ship's accommodation to form a positive pressure, and then enters the cabin corridor through the ventilation duct. Finally, it returns to the air-conditioning processing unit through the return air duct to form a cycle. Generally, the corridor and the atmosphere are connected through the ventilation duct to maintain the air pressure balance.

[0003] The existing ventilation duct pressure regulation equipment has a too complex structure. When in use, the amount of regulation cannot be controlled, and the device is relatively fixed, not convenient for disassembly, repair, and difficult to install between ventilation ducts with different intervals. Therefore, we provide a pressure regulation device for a ship cabin air-conditioning ventilation duct. Summary of the Utility Model
