Ship ventilation system

Abstract

The invention provides a ship ventilation system which comprises a ventilator with an inner air opening and an outer air opening, the inner air opening of the ventilator is connected with a ventilation main pipe, the ventilation main pipe is provided with ventilation branch pipes communicated with all cabins, and the tail end air openings of the ventilation branch pipes are located in the corresponding cabins. Axial fans and electric heating nets are arranged at the tail end air openings of the ventilation branch pipes, the axial fans and the electric heating nets are electrically connected with the control panel, and by adjusting the gears of the axial fans in the ventilation branch pipes, the amount of air entering the corresponding cabins is adjusted so as to meet the ventilation requirements of the different cabins; and the electric heating net is arranged to heat air in the corresponding ventilation branch pipes, so that the heat preservation requirement of some cabins is met, and people or goods in the cabins are prevented from being frozen.

Description

technical field [0001] The invention belongs to the technical field of ventilation systems, and in particular relates to a ship ventilation system. Background technique [0002] The current ship ventilation system is divided into natural ventilation and mechanical ventilation. Due to the large resistance along the air duct, the natural ventilation without pressure often cannot achieve a good air intake and exhaust effect, and can only achieve the effect of balancing the cabin air pressure; Although the mechanical ventilation is equipped with a large fan for the air intake and exhaust of each cabin, the air volume of the vent near the large fan is large, and the air volume of the vent far away from the large fan is small, which cannot meet the ventilation of different cabins Require. [0003] In addition, with the large-scale development of ships, the electricity required for daily work and life of the crew continues to increase. If we continue to rely on burning non-renewab...

[0002] The current ship ventilation system is divided into natural ventilation and mechanical ventilation. Due to the large resistance along the air duct, the natural ventilation without pressure often cannot achieve a good air intake and exhaust effect, and can only achieve the effect of balancing the cabin air pressure; Although the mechanical ventilation is equipped with a large fan for the air intake and exhaust of each cabin, the air volume of the vent near the large fan is large, and the air volume of the vent far away from the large fan is small, which cannot meet the ventilation of different cabins Require

[0003] In addition, with the large-scale development of ships, the electricity required for daily work and life of the crew continues to increase. If we continue to rely on burning non-renewable energy to obtain electricity, it will not only emit a large amount of pollutants, but also accelerate the depletion of non-renewable energy. The light is strong, inexhaustible, if not utilized, it will be a great loss

[0004] Furthermore, sea conditions are changing, and severe weather that occurs rapidly (that is, has a short life history) is prone to occur, such as storms, typhoons, etc. If these severe weather are not predicted in time and measures are taken, it will greatly affect the safety of maritime navigation. threaten
