Description

Technical Field

[0001] The utility model belongs to the technical field of ship ventilation, and particularly relates to a fan room for a ventilation system of a cargo hold of a car transport ship. Background Art

[0002] A PCTC is equipped with access equipment such as stern doors and ramps, and is a special transport ship for large-scale marine automobile transportation. In the closed cargo hold of a PCTC ship, cars will produce exhaust when getting on and off the ship, causing harmful gases such as carbon monoxide to be contained in the air. Even when the car is stationary, the car fuel system may volatilize flammable gases. In order to ensure the health of the workers in the cargo hold, the cargo hold ventilation system injects fresh air from the outside to maintain the air quality in the cargo hold. The cargo hold of a PCTC ship has a large volume, and the regulations require a very high ventilation frequency, which is generally 10 times per hour when sailing at sea and 20 times per hour when loading and unloading, so the ventilation system is very large.

[0003] The cargo hold ventilation system of PCTC ships is mainly composed of fan room and structural air duct, and the most critical part is the fan room. Fans, wind dampers, silencers, etc. are arranged in the fan room. The operation of fans will generate a lot of power consumption and noise, and the cost of the fan room is relatively high. It is the key technology and main difficulty in the design and construction of PCTC ships. Utility Model Content
