Description

82306

The invention relates to a ventilation system.

The ventilation arrangement of the cabins of ships is usually formed by an equipment solution in which a terminal for fresh ventilation air is arranged on the ceiling of the cabin space. The disadvantages of the above-mentioned known solution are the loud noise caused by the supply air and the feeling of traction caused by the supply air. Especially in cabin solutions where the cabin space comprises a bunk bed, there are problems with ceiling blowing, especially for those staying in the upper bed. The feeling of traction, especially near the ventilation terminal, is strongest.

The object of the invention is to provide a ventilation system which has been able to avoid the above-mentioned drawbacks.

The object of the invention has been achieved by a solution in which it is realized that the supply air terminal member is located close to the floor level of the room space and in particular under a bed in a fixed position. The invention has been able to achieve e.g. the following significant benefits. It has been possible to take advantage of free otherwise unused space. The supply air terminal member has been able to be positioned so that the air flow it produces is not directly on the people living or working in the 25 rooms. The terminal member of the ventilation system according to the invention can be easily installed in the rooms. The invention has realized the use of furniture in fixed locations to control the air flow and, on the other hand, to prevent the air flow in certain directions.

30

The ventilation system according to the invention is mainly characterized in that the supply air device is arranged in a space below the fixed bed, which space is bounded above by the bed mattress and supporting members, which mattress acts as a , in which case higher velocities are allowed for the air discharged into the cabin space.

The invention has realized the use of an air-impermeable surface element of furniture. In this case, it has been possible to take advantage of the space above the surface element for a purpose which might otherwise be disturbed by the flowing air. The surface element can be, for example, a bed mattress and / or an element supporting 5 mattresses, whereby the space above the element in question provides a draft-free and comfortable resting and bed space according to the invention.

The system can be used in connection with cabins in which cabin 10 is intended as a passenger or long-term living space, service space, common space such as a canteen, or the like in a ship or floating marine structure. The system can be utilized in connection with a cabin equipped with a service cabinet. The air is first introduced centrally into the service closet of each cabin, hence individually along the ventilation duct 15 of this cabin to the supply air device.

When the system according to the invention is used in the air-conditioning of passenger cabins on ships, fresh air is first introduced into the cabin service compartment, which is preferably located in a modular cabin so that the service compartment can be opened towards the ship's corridor. The service compartment comprises a door that opens into the entrance. This makes it easy to adjust and maintain the ventilation equipment. Fresh air is brought in through the service closet and is further led along the air duct, e.g. through floor structures, to the cabin space itself via a ventilation terminal that opens there.

25

However, the invention is not intended to be limited to passenger-cabin use alone, but in a broader embodiment of the invention, the ventilation system can be used in general as a ventilation system for hotel rooms and the like in accommodation facilities.

The invention will now be described with reference to some preferred embodiments of the invention shown in the figures of the accompanying drawings, to which the invention is not intended to be exclusively limited.

Fig. 3B shows a top view of the cabin structure of Fig. 3A and shows in particular the air discharge pattern.

Figure 1 shows a prior art cabin arrangement on a ship. Air is introduced to the ventilation terminal S1 via the air duct S, '. Ventilation terminal S, located in the roof of cabin space H,. Thus, the fresh supply air causes a considerable feeling of traction, especially in a cabin with a bunk bed for a person staying in an upper bed. The supply air device also makes a significant noise because the supply air 20 can be discharged into the cabin space without damping. In Figure 1, two adjacent cabins H ,, H, are marked. The floor structure of the cabins is marked with the letter L, the wall with the letter Q and the deck structure with the letter R. The hull beams P ,, P2, ... are with a certain distribution under the structure R. When placing the cabins H ,, H ,, ... in the floor space L, the difficulty in the solution of the prior art 25 is that the distance d ,, dj between the frame beams Pt, P2 ... and the cabin wall Q ,, Q2. . . does not become constant, but each terminal member S ,, S2 of the ventilation system must be installed on a cabin-by-cabin basis due to space problems caused by the beams P ,, P2, ... The ship's cabins Η ,, Η ,, ... are pre-built at the factory and only 30 are installed on the ship. Thus, a large number of different cabins are formed, with the only difference being the location of the ventilation terminal on the roof.

This makes the installation of cabins time consuming and very cumbersome.

Figure 2A is a plan view of a ship's cabin arrangement. Cabins 35 H, ... H, are modularly adapted to each ship block. Each cabin 4 82306 H, ... H, comprises a service space, i.e. a service cabinet K, ... K ,, through which air can be led to the supply air device in the cabin space H, ... Hg.

Fig. 2B shows a floor plan of a cabin H and also shows an arrangement of a ventilation device according to the invention. According to the invention, fresh air is introduced into the ventilation terminal member 10 via the air duct 11. The ventilation terminal member 10 is adapted to be located below the bed 13 and the mattress 13b of the bed 13 near the floor. Figure 2B shows the discharge pattern of the air discharged from the terminal member 10 by 10 T. The throw pattern is located substantially below the bed 13. Thus, the air passing under the bed 13 enters the space 14 next to the bed substantially without impulse and velocity. The exhaust air duct is adapted to be located at the top of the cabin near the roof. The exhaust air duct may comprise a control valve for controlling the amount of air leaving the cabin. The air 15 is introduced centrally to the service cabinet Κ ,, Κ ,, ... of each cabin and from there it is led along the duct 11 to the supply air device 10, from which it is arranged to discharge into the free space 12 below the furniture, preferably the bed 13 (arrow L,).

‘. Figure 3A shows a ventilation solution for a room space according to the invention, in particular a cabin. The cabin is shown in a side view. The cabin comprises fixed beds. The lower bed 15 and the upper bed 16 are placed on top of each other. The air inlet terminal 10 is arranged under the lowest bed 15. Thus, both the terminal member 10 and the mattress 15b of the bed 25 attenuate the sound of the supply air and thus the cabin space is noise-free. The supply air discharge pattern T is also located substantially below the bed 15 in the free space 12 and thus the air flow under the bed enters the actual living zone 14 without high speed and further exits the cabin through the exhaust duct 17 at the top of the cabin space. The exhaust duct 17 30 may comprise an adjustable valve 18 in the cabin space, e.g. a check valve, by means of which the amount of exhaust air can be adjusted. Air entering the room from the terminal member 10 is indicated by arrows L, and air leaving the cabin space is indicated by arrows Lj.

Figure 3B shows a top view of the cabin solution of Figure 3A. Shown is the throw pattern T. It can be seen from the figure that the throw pattern remains substantially under the bed IS.

5 The planar element controlling and damping the air flow can be an air * tight plate. However, this level element can also consist only of the bed mattress. It is essential, however, that the effective airflow throw pattern is effectively limited vertically below said planar element, e.g. a mattress.

The cabin ventilation according to the invention allows the supply air device to be invisible. The fitting of the supply air device specifically under the stationary bed also makes it possible to have higher speeds under the bed without the risk of traction for the person in the cabin 15. In this way, it is also possible to take advantage of the completely useless space under the bed. The supply air device also holds sound-absorbing material, and the bed also acts as a silencer, and therefore no sound is caused by fresh air being blown into the ears of a person sleeping in the cabin. The ventilation system according to the invention considerably improves cabin comfort. The solution according to the invention also enables advantageous utilization of heat in the cabin space. The heat is always brought down because the heated air is brought in from below. Thus, according to the invention, the cabin space can be heated advantageously using air heating. When the supply air device is located at the bottom of the cabin space, the warm air 25 rises upwards and exits through the exhaust air duct 17.
