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 outboard expansion type air conditioner.

Conventionally, a gas detection sensor is provided at an air intake port of the outboard expansion type air conditioner, and a duct is provided with a blocking damper for blocking the suction of the outside air to cut off the duct at the time of gas leakage. 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 outboard expansion type air conditioner long 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.

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. In addition, since the outside air suction duct 300 is rotatable, the air inlet 30 can be moved from the gas leakage point or the gas cloud formation to another as needed, without shutting down the air conditioner .

As a result, the outboard expansion type air conditioner which can receive fresh outside air can be implemented.

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 installed on the hull 100. The outside air suction body 200 is a structure that interconnects the outside air suction duct 300 to be described later and the air conditioner 400 in the hull 100. [

For example, the outside air suction body 200 may have a cylindrical 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. That is, the outside air suction duct 300 can be formed to extend outside the hull 100 without occupying a space of the hull 100. Accordingly, the outside air suction duct 300 can satisfy the design criteria of the gas retention time, and can reduce the wasted space by extending the duct to satisfy the design criteria. As a result, The space utilization of the user can be increased.

Referring to FIG. 3, the external air suction duct 300 forms a structure extending in the horizontal direction from the external air suction body 200. Although not specifically shown in the drawings, the outside air suction duct 300 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.

At this time, one end of the outside air suction duct 300 may be coupled to the outside 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.

Referring to FIG. 1, as the air intake port 310 is located far away from the center of the hull 100, fresh air can be relatively inhaled compared with the conventional method of sucking the outside air directly from the central region of the hull 100 . 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 outboard expansion type air conditioner 1000 is cut off and the operation of the air conditioner is interrupted.

The second gear 620 may be installed in the inner space of the outer air suction body 200 to engage with the first gear 610. The second gear 620 may be, for example, a pinion gear.

The motor 630 is a power unit that provides a rotational force to the second gear 620. To this end, the motor shaft of the motor 630 may be fixedly coupled to the second gear 620.

The outer air suction body 200 can be rotated with respect to the hull 100 in accordance with the driving of the driving unit 600 so that the air sucked through the outer air suction duct 200 extending outwardly from the outer air suction body 200 300 can rotate together with the outside air suction body 200 as shown in FIG.

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

Although not shown, in addition to the above-described embodiments, the outside air suction body portion 200 can be modified into various forms. For example, the outside air suction body 200 may include a lower body fixed to the deck of the hull 100, and an upper body installed to be rotatable with respect to the lower body. In this case, the motor 630 of the driving unit 600 may be fixedly supported on the lower body, and the first gear 610 may be formed in an annular band shape on the upper body. Accordingly, the upper body can be rotated with respect to the lower body according to the driving of the motor 630, and the outside air suction duct 300 extending from the external air suction body 200 can be rotated You can exercise.

In this embodiment, the outer air suction body 200 is rotatable with respect to the hull 100. However, the present invention is not limited to this, And the air sucking duct 300 may be rotated with respect to the air sucking body 200. [
