Air diffuser is also called cabin unit, it is a kind of terminal unit of marine air conditioning system.
Ceilding Air Diffuser is mainly composed of static pressure box, air volume regulator and diffuser. The air volume has the function of primary air volume limit and secondary air volume regulation. The primary limit mechanism of transmission is used to balance the air volume, so that the air volume distribution reaches the design value. The Secondary air volume is manually adjusted by the crew's own comfort level.

An azimuth thruster is a configuration of marine propellers placed in pods that can be rotated to any horizontal angle (azimuth), making a rudder unnecessary. These give ships better maneuverability than a fixed propeller and rudder system.
360 degree Azimuth thrusters are for main propulsion and steering of displacement vessels. They are available from 45kW to 2205kW to replace conventional propulsion and rudder steering systems to perform both the propulsion and steering functions.
Azimuth thrusters are used when enhanced maneuverability is required in applications such as dynamic positioning, ship escort and ship docking services.
Azimuth thrusters are available in Z-drive configuration with direct diesel engine drive or in L-drive configuration for electric or hydraulic drive from overhead.
The propeller rotates 360 degrees around the vertical axis so that the thruster can perform both the propulsion and steering duties for a vessel, or positioning for a semi-submersible rig, drillship or FPSO.
Types of azimuth thrusters
1.Mechanical transmission, which connects a motor inside the ship to the outboard unit by gearing. The motor may be diesel or diesel-electric. Depending on the shaft arrangement, mechanical azimuth thrusters are divided into L-drive and Z-drive. An L-drive thruster has a vertical input shaft and a horizontal output shaft with one right-angle gear. A Z-drive thruster has a horizontal input shaft, a vertical shaft in the rotating column and a horizontal output shaft, with two right-angle gears
2.Electrical transmission, more commonly called pods, where an electric motor is fitted in the pod itself, connected directly to the propeller without gears. The electricity is produced by an onboard engine, usually diesel or gas turbine.
3.Mechanical azimuth thrusters can be fixed installed, retractable or underwater-mountable. They may have fixed pitch propellers or controllable pitch propellers. Fixed installed thrusters are used for tugboats, ferries and supply-boats. Retractable thrusters are used as auxiliary propulsion for dynamically positioned vessels and take-home propulsion for military vessels. Underwater-mountable thrusters are used as dynamic positioning propulsion for very large vessels such as semi-submersible drilling rigs and drillships.
Primary advantages are electrical efficiency, better use of ship space, and lower maintenance costs. Ships with azimuth thrusters do not need tugboats to dock, though they still require tugs to maneuver in difficult places
Drive type of the Azimuth propeller:Electric motor drive,Engine drive,Hydraulic motor drive.
Installation:Deck installation,well installation,Transom installation.
According to propeller type, it can be divided into Controllable-pitch propeller(CPP) type and fixed-pitch propeller(FPP) type.
According to installation type it can be divided into vertical installation type and horizontal installation type.
Ship bow thruster, also known as the bow thruster, the main function is for ships provide the side thrust of the first, meet the ship small rotation angle of pivot steering (normal ship no bow thruster of requires turning radius is at least twice as captain), waves can also provide lateral thrust to balance the yaw moment to stay the course. Direction of motion is the direction of the ship's heading.
A bow thruster is a transversal propulsion device built into, or mounted to, either the bow , of a ship or boat, to make it more maneuvrable. Bow thrusters make docking easier, since they allow the captain to turn the vessel to port or starboard side, without using the main propulsion mechanism which requires some forward motion for turning; indeed, the effectiveness of a thruster is curtailed by any forward motion due to the effect. Large ships might have multiple bow thrusters
Thruster mainly in the ship sailing in narrow waterway, on the docks or back, through the traditional steering difficult or unable to operate the equipment operation is good tool, is often used in the bad environment in operation of the ship.
Thrust in used to rely on when you leave the terminal operation, have very good effect, can save a lot of tug use cost, generally 3 ~ 5 years can see benefits.
1.High performance and great durability
Robust and easy-to-handle , high durability has been achieved.
2.Low level of vibration and noise
Fine design considerations given to duct structure and thickness in order to reduce vibration and noise in living space when thruster is in operation.
3.Easy to install and maintain
Thrusters have a structure without duct ribs to ensure they can be fitted by welding to any part of the exterior surface of the duct. Only the seal in the rotating part needs regular replacement, which reduces the hassles of maintenance.
4.Wide variety of drive systems
Compatible with electric motors, engines and hydraulic motors, thrusters can be used in a wide variety of configurations.
