Marine or marine structures with a variety of uses in the marine environment are equipped with facilities that can harm human bodies (eg TOP SIDE modules installed on LNG FPSO), which are harmful to human body. In case of leakage, there is a possibility that the leaked gas flows into the interior space of the hull through the air inlet of the air conditioner.

In order to remove such a human body component, conventionally, a gas detection sensor is installed in the air intake port of the air conditioner, and a duct is provided with a blocking damper for blocking the suction of the outside air to cut off the duct when the gas is leaked. However, when the gas detection sensor confirms the presence of the gas contained in the outside air, the outside air including the gas reaches the blocking damper for blocking the air suction from the air inlet for a predetermined time (i.e., gas retention time It is necessary to make the duct of the air conditioner longer in accordance with the gas retention time determined by the gas flow rate from the point where the gas detection sensor is installed to the point where the blocking damper is installed. Accordingly, there is a problem that space utilization of a hull having a limited space is reduced.

FIG. 1 is a view showing an outboard expansion type air conditioner according to an embodiment of the present invention, and FIG. 2 is a schematic view illustrating the air conditioner shown in FIG. 1 as an emergency exit. 3 is an enlarged view of a driving unit of the air conditioner shown in Fig.

1 to 3, the outboard expansion type air conditioner according to an embodiment of the present invention may include an outside air intake body 200, an outside air intake duct 300, and an air conditioning unit 400.

According to the present embodiment, it is possible to satisfy the design criteria of the gas retention time, which is the time required for the outside air including the gas to reach from the air intake port to the blocking damper for blocking the air intake, It is possible to reduce the wasted space by extending the duct for long), it can improve the space utilization of the hull compared to the existing one.

Also, according to the present embodiment, by separating the air intake port 310 as far as possible from the danger zone in the hull, it is possible to place the air intake port 310 far away from the dangerous space in the hull, have. Thereby, the air inlet 30 can be spaced apart from the gas leakage point or the gas cloud formation, if necessary, without shutting down the air conditioner. Accordingly, it is possible to implement a front-view expansion type air conditioner which can receive fresh outside air.

In addition, according to the present embodiment, the outside air suction duct 300 is extended not only to satisfy the retention time, but also can be used as an escape route so that the crew can quickly escape outboard.

Hereinafter, a specific configuration of the outboard expansion type air conditioner according to the embodiments of the present invention will be described with reference to FIG. 1 to FIG.

The offshore structure is a structure including the hull (1000). Here, the offshore structure may include various marine plants as mentioned above. The term " offshore structure " as used herein refers to a concept that encompasses all types of linear vessels operating in the ocean, such as LNG carriers, as propulsion propulsion vessels.

The outside air suction body 200 may be fixedly mounted on the hull 100. That is, the outside air suction body 200 is a structure fixed to the hull 100, and can connect the outside air suction duct 300, which will be described later, and the air conditioning unit 400 in the hull 100 with each other.

The outside air suction body 200 may be formed of, for example, a cylindrical or box-shaped structure, and a flow path for connecting the outside air suction duct 300 and a connecting duct 400, which will be described later, .

According to the present embodiment, the outside air suction duct 300 can be formed to extend from the outside air suction body portion 200 to the outside of the hull 100. As shown in FIG. Specifically, the outside air suction duct 300 may be formed into a spiral shape such that it is extended to the outside of the ship 100. Accordingly, the outside air suction duct 300 can satisfy the design criteria of the gas retention time and reduce the wasted space due to the extension of the duct to satisfy the design criteria. In other words, The space utilization of the hull 100 can be increased compared with the conventional one.

The outer air suction duct 300 may extend downward from the outer air suction body 200 to the side of the hull 100. One end of the air suction duct 300 may be connected to the outer air suction body 200 And an air inlet 310 may be formed at the other end of the outside air suction duct 300.

Therefore, fresh outside air can be sucked into the outside air intake duct 300 through the air intake port 310 provided at the other end of the outside air intake duct 300. The outside air thus sucked is passed through the outside air intake body part 200 And may be supplied to the air conditioning unit 400 inside the hull 100.

That is, according to the present embodiment, as the air intake port 310 is located far away from the center of the hull 100, as compared with the conventional method of sucking the outside air directly from the central area of the hull 100, have. In addition, even if gas leaks from the central region of the hull 100, as the gas is diluted in the air, the amount of the gas sucked through the air inlet 310 remote from the center of the hull 100 will be very low, It is possible to minimize the case where the outside air suction of the air conditioner 1000 is interrupted and the operation is interrupted.

Referring to FIG. 2, a door 210 may be installed on the outside air suction body 200. The door 210 may be used as an escape path through which a source of the emergency can escape to the lifeboat 10 through the outside air suction duct 300. At this time, the outside air suction duct 300 may be formed in a spiral shape having an inclination allowing the escape person to slide so as to be used as an escape hole in an emergency.

The air conditioning apparatus 1000 according to the present embodiment may further include a support portion 600 for supporting the outside air suction duct 300 to the outside air suction body portion 200. The support portion 600 may be formed of a bar-shaped frame that can fix the outer air suction duct 300 of the twist-like shape to the air suction body 200.

At this time, the bar-shaped support part 600 can be hinged around the hinge rotation axis 610 to the outside air suction body part 200. Accordingly, as the supporting portion 600 rotates about the hinge rotation axis 610, the outside air suction duct 300 can be rotated with respect to the outside air suction body 200 as shown in FIG.

Since the external air suction duct 300 is rotatable with respect to the external air suction body 200, the inclination angle of the external air suction duct 300 with respect to the sea surface can be adjusted. Accordingly, when the emergency escape of the crew is required, the inclination degree of the outside air suction duct 300 can be easily adjusted according to the height of the hull 100 with respect to the sea surface, and the crew can more safely escape the hull 100 have.

For this, the air conditioning apparatus 1000 according to the present embodiment may further include a driving unit 700 that rotates the supporting unit 600 with respect to the air sucking body unit 200.

In this case, the actuator may comprise, for example, a piston / cylinder mechanism operated by hydraulic or pneumatic pressure, and may further comprise an accessory device for providing hydraulic or pneumatic pressure to the piston / cylinder mechanism. Referring to FIG. 3, the driving unit 700 including the actuator is stretchable and contractible in the longitudinal direction so that the helical outer air suction duct 300 rotates about the hinge rotation axis 610 with respect to the outer air suction body 200 You can exercise.

As the driving unit 700 is driven as described above, the rod-like supporting unit 600 can be rotated so as to vary the tilt angle with respect to the outside air suction body 200.

Accordingly, the position of the air inlet 310 of the air conditioner 1000 can be varied as needed when operating the ship or the offshore structure in the ocean. In addition, when the ship or the offshore structure is moved to another place, the outside air suction duct 300 projected outside the hull 100 can be moved to the hull 100, thereby preventing a safety accident during navigation.

Meanwhile, although not shown in the drawing, the outside air suction duct 300 may be detachably coupled to the outside air suction body 200. Accordingly, when the emergency air intake duct 300 is separated from the air intake body 200 in an emergency, it can be utilized as an emergency lifeboat. To this end, the outside air suction duct 300 may be made of a material that can float on the water surface, that is, a material having buoyancy.

1, the outside air suction duct 300 is capable of extending and contracting in the longitudinal direction (see the arrows in FIG. 1) from the outside air suction body 200. In this case, the outside air suction duct 300 can be stretched and contracted through the support portion 600 which can be stretched and contracted in the longitudinal direction. Although not specifically shown in the drawings, the support portion 600 may be configured in the form of a multi-stage telescoping boom. In this case, the multi-stage telescoping boom is capable of stretching movement in the longitudinal direction through, for example, a hydraulic actuator.

Since the outside air suction duct 300 can be expanded and contracted in the longitudinal direction according to need, for example, the inclination angle of the outside air suction duct 300 with respect to the sea surface can be adjusted so as to secure a safe inclination when the source is escaped have. Further, the air inlet 310 can be spaced farther away from the gas cloud, if necessary, so that the air conditioner can be continuously operated without shutting down due to gas leakage.

Meanwhile, a gas detection sensor 800 capable of detecting the presence or absence of gas in the outside air may be installed in the air inlet 310.

The air conditioning apparatus 1000 according to the present embodiment may further include a connection duct 500 connecting the air intake unit body 200 and the air conditioning unit 400. The connecting duct 500 may be provided with a blocking damper 900 to block the inflow of gas when the gas is detected in the outside air.

As described above, according to the embodiments of the present invention, it is possible to satisfy the design criteria of the gas retention time and to improve the space utilization of the hull, and to improve the air intake from the danger zone in the hull It is possible to realize an outboard expansion type air conditioner which can receive fresh outside air by separating the outside air.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention as set forth in the appended claims.
