Description
Technical field
The present invention relates to a kind of marine air conditioning and force ventilation device, particularly a kind of isolated noise reduction ventilation terminal.
Background technology
Because in recent years, the order of Chinese working ship gradually moves towards medium-to-high grade, such as Middle East, European countries, these countries
Higher is required to the comfortable working environment degree of crewman.Such as to have to working environment vibration, noise, illuminance clearly
Ask, also have clear and definite regulation in the character of class Hab of correspondence classification society.Due to present ventilation terminal maximum air output when, exert oneself
Requirement can be reached by force, once air quantity is turned down, noise is at once exceeded, not be suitable for using on the ship with Hab symbols, this every
Mainly pass through from formula noise reduction ventilation terminal technical principle with a distance from insulating noise source and room, and increase muffler in centre,
So as to reduce noise.
Conventional air outlet ventilation terminal has following 2 kinds at present：
One kind is to be directly entered ventilation terminal by airduct, carries out air draft with square and circular air outlet regulation air quantity, does not have
A bit noise reduction, air quantity is small to increase noise on the contrary, this to belong to archetype.
Two kinds are to increase one bigger than airduct section 1.5 ~ 2 times of square or circular structure between wind-distributing pipe and ventilation terminal,
Again air draft is carried out with air outlet regulation air quantity.
Although the ventilation terminal of the second relatively primitive type has been to reduce the noise of many decibels, for there is comfort level Hab requirements
The ship of high added value still can not meet requirement.The 10 70 meters of Multipurpose anchor workmanships accepted for 2012 as our companies
It is all band Hab character of class that 6 79 meters of Multipurpose anchors for making ship and 2013 to accept, which make workboat, to the noise on ship, vibration,
Illuminance has higher requirement, and the noise for solving force ventilation and air conditioner ventilation on ship is a great problem of our these ships tackling key problem
One of, this just turns into the free-revving engine of this practical research.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides the isolated muffler that a kind of noise is low, vibration is small, solved
