AIR CONDITIONING EQUIPMENT, METHOD AND AIR CONDITIONING ROOM

ENGINEERING

5

The present invention relates generally to ventilation. In particular, but not exclusively, the invention relates to air-conditioning of a ship cabin.

TECHNICAL BACKGROUND

10

Ventilation systems are commonly used in ship cabins for ventilation, in which a terminal air conditioning unit is installed above the cab roof and the exhaust air is handled by means of a separate duct, eg a duct mounted above the roof. The terminal is supplied with filtered air 15 through an inlet duct. The terminal, in turn, supplies air to the cabin via a supply air diffuser (i.e., diffuser) or similar mounted on the ceiling.

Depending on the system, the cabin occupant may also control the operation of the supply air terminal with a control unit mounted on the cabin wall. Typically, the user may, for example, set the cabin temperature lower or higher. The airflow to the cabin (for example, flow rate, temperature, or both) is adjusted based on user control settings and any other system settings such that cabin air conditioning conditions best meet the occupant's needs and requirements.

CVJ

ό The ventilation unit is installed above the roof of the cabin, either at the shipbuilding stage at the shipyard or, increasingly, at the cabin factory besides the manufacture of cabins x. Finished cabin modules are typically installed on board

CL

by pushing them into place on the ship's deck and securing them to the ship's S 30 hull. Because the space between the ship's decks and cabin modules in the vertical direction is tight, the terminal device cannot in practice be in its stationary position in the operating position.

CVJ

when pushed on board. Because the terminal typically extends significantly above the cabin ceiling when attached to the cabin ceiling, the terminal may strike the horizontal beam of the ship 2 and break when the cabin module is pushed into the ship, or may even prevent the cabin from being fully installed.

The above problem has been solved in one known embodiment 5 by using a flexible accordion tube as the inlet pipe at the air inlet end of the supply air terminal and by dropping the terminal with the accordion tube during cabin installation. During the commissioning phase, the terminal is lifted back into position above the cabin roof. However, there is a problem with this solution that the accordion tube may be damaged if bent. 10 It may dent or warp so that it affects the supply air flow to the terminal and typically also temperature control.

SUMMARY

15 in accordance with the invention, a first aspect of the air conditioning apparatus, comprising: a terminal which is adapted to be secured to be conditioned to the operating position in the ceiling at least partially above the roof, the terminal comprising: a feeding air supply side of the supply air terminal device.

The air-conditioning system comprises: a sliding and swinging mechanism for dropping the terminal through a hole in the ceiling to the side of the air-conditioned space supported by the supply air supply side upstream of said mechanism.

CVJ

The said mechanism (or means) may comprise means for sliding and oscillating ό. The devices may or may be attached to or connected to the terminal, or partly to the terminal and partly to the terminal, x Depending on the embodiments, for example, special slide rails and / or slot parts and / or

CL

rods, pins and / or projections moving and / or attached thereto

C/O

The S 30 can be mounted either on the terminal, on the ceiling of the room to be ventilated and / or on a special mounting frame or rail or the like.

CVJ

In some embodiments, said mechanism is a drop mechanism that allows the terminal 3 to be dropped into a particular supported position. There are two types of support or a combination of these. In the first method, the terminal is dropped into a supported position where the terminal itself is supported by the hardware. In this case, for example, the terminal may remain suspended on the drop mechanism 5. In another way, the terminal is dropped directly from the drop mechanism, whereby the terminal itself is not supported by the hardware, but rather by the installer or the like.

In some embodiments, the air conditioning system comprises a mechanism (or means) for moving or dissolving the terminal device horizontally in and out of the duct adapter. In some embodiments, said mechanism is adapted to release the terminal device from said mechanism when the terminal device is moved or disengaged from the tube adapter for a predetermined distance.

In some embodiments, the air conditioning system comprises a combined sliding and rotating mechanism (or means) for dropping the terminal by swinging it down into said supported position downstream of the supply air supply. In some embodiments, such a solution, in which the terminal is rocked down, is called a swingdown mechanism. Such a swingdown mechanism may be implemented, for example, using a mounting frame or using separate mounting rails. The swingdown mechanism may include support bars or rails attached to the terminal, which are secured to the support bars above the roof of the room to be ventilated (e.g., ship's cabin). The terminal can be swung down, for example, before the ship cabin is installed, and during the commissioning phase, the terminal can be raised

CVJ

0 25 back into position above the roof. The terminal can be fixed in place ό, for example, to a supply air duct adapter (ie adapter), at one end of which i m is fixed, or the supply air duct is attached via an accordion tube or the like.

CC

CL

In some embodiments, the air-conditioning apparatus comprises a ceiling mounting frame made of non-combustible material S 30 which completely surrounds said ceiling opening. In some

CVJ

in embodiments, the mounting frame covers a certain amount (e.g., 25 mm) of the roof opening above each opening to meet certain fire safety requirements.

4

In some embodiments, the air conditioning apparatus comprises a mechanism comprising a sliding mechanism and a combined sliding and rotating mechanism, the sliding mechanism allowing for dissolution of the terminal and a combined sliding and rotation mechanism of the combined sliding and rotating movement of the terminal. Rotation may be allowed around a particular axis of rotation.

In some embodiments, the air conditioning apparatus 10 comprises an air supply connected to the inlet side of the plurality of pyörteilynvähennyslevyjä. The apparatus may comprise said turbulence reduction discs, regardless of other embodiments, and whether or not there is a mechanism for dropping the terminal through a hole in the ceiling to the side of the air conditioner to be ventilated upstream of the supply air. In accordance with one aspect of the invention is thus carried out in apparatus for conditioning, the apparatus 15 comprises in connection with the air conditioning the air input side of the plurality of intake air pyörteilynvähennyslevyjä. In some embodiments, the plates are oriented in the direction of supply air supply, thereby facilitating the formation of a laminar flow. When the plates are parallel to the supply direction, the tangent to their surface is parallel to the supply direction and is normal to the surface normal to the supply direction. The vortex reduction plates may be located, for example, in the supply air duct adapter. They may be co-located.

According to another aspect of the invention there is provided a process wherein:

CVJ

o 25 moving the ceiling of the air-conditioned space at least partially above the roof ό an air-conditioning supply air terminal that can be secured between the operating position and i m a supported position, whereby: x moving the terminal within the air conditioning sliding and swinging

CL

supported by a permissive mechanism between said operating position and a supported position S 30 through a ceiling opening in a position where the supply air supply side is o towards the space to be ventilated.

CVJ

In some embodiments, the method drops the terminal device from the operating position 5 to the aforementioned supported position through an opening provided in the ceiling of the room to be ventilated, the supply air supply side of the terminal being upstream.

In some embodiments, the method lifts the terminal, from the aforementioned supported position to the operating position, through an opening in the ceiling of the space to be ventilated, facing the supply air side of the terminal.

In some embodiments, the method moves or slides the terminal device 10 substantially in or out of the tube adapter. In some embodiments, the method swings the terminal down into said supported position with the supply air supply side down.

In some embodiments, the method permits the terminal to be flagged by a sliding mechanism, and allows the combined terminal to be flagged and rotated around the axis of rotation by the combined terminal flag and rotation mechanism in a condition where the terminal is disengaged from said sliding mechanism.

In some embodiments, the method reduces the turbulence of the supply air 20 by a plurality of turbulence reduction discs. The turbulence of the supply air can be reduced by a plurality of turbulence reduction plates, regardless of other embodiments, and whether the method moves at least partially the ceiling-mounted supply air terminal between the operating position and a supported position. Thus, according to one aspect of the invention, there is provided

CVJ

o A method of reducing the turbulence of the supply air by a plurality of yör turbulence reduction discs placed in connection with the air conditioning system.

When the terminal is moved according to some embodiments of the invention

CL

on the roof of the room to be ventilated backwards so that the device oscillates down into the supported position S 30 in front of the supply air supply pipe end, in some embodiments it may be advantageous for o in such a solution to accommodate the terminal

CVJ

to the side of the room to be ventilated (e.g. inside the cabin), typically with a smaller opening than usual. This, in turn, typically allows for a smaller diffuser size of 6.

For example, if said duct adapter includes turbulence reduction plates (e.g., lamellae) to compensate for air turbulence, adjusting the air conditioning system is easier in certain systems, particularly those where the supply air duct pressure is measured or at least partially based on differential pressure measurements.

According to a third aspect of the invention there is provided an air-conditioned living room comprising an air-conditioning apparatus comprising any of the first aspects or embodiments thereof, wherein said living room is, for example, a hotel room or a cabin for a ship or other vehicle.

Figure 1 shows a three-dimensional view of an air-conditioning system according to an embodiment. The air conditioning system comprises a terminal 110, a mounting frame 115 and a pipe adapter 120. In Figure 1, the terminal 110 is in a down position (e.g. for maintenance) where it hangs with its sliding members 140a, 140b.

o 25 pins (or support bars) 141a, 141b of mounting frame 115. The terminal comprises ό supply air inlet conduit 130, supply air outlet conduit 125 and (quick) connectors 170 µm, and a strain relief 175 for electrical connections. The terminal 110 has integrated or x-attached projections 151a, 151b that fit into the corresponding mounting frame

approaching the upper position to move within the slot portions 160a, 160b of their ends 161a, 161b, which have a widening or other arrangement that allows for inward movement. The projections 151a, 151b can be implemented, for example, by a mounting rib 150 attached to the terminal 110, whose bent ends form said projections 151a, 151b. In an upright position, the terminal 110 may be further slid horizontally to an operating position in which the supply air inlet conduit 130 is secured to the duct adapter 120. The duct adapter 120 is in turn secured to the supply air duct by, for example, a flexible conduit, accordion tube, throat. In one embodiment, the tube adapter 120 comprises lamellae 180 to reduce turbulence in the supply air.

Fig. 2 is a side cross-sectional view of the apparatus of Fig. 1 with the terminal 110 in the lowered position. The terminal 110, with its sliding member 140a, hangs on the ceiling 210 of the space to be ventilated (e.g., ship's cabin) from the pin 141a of the removably or permanently mounted mounting frame 115, the terminal 110 extending to the side of the ventilated space.

Figure 3 is a side cross-sectional view of the apparatus shown in Figure 1 with the terminal 110 in a down position and an intermediate position between the operating position.

Figure 4 shows a side cross-sectional view of the apparatus of Figure 1 with the terminal 110 in the operating position. The terminal 110 is in the operating position at least partially above the ceiling of the space to be ventilated, in some embodiments substantially above the ceiling.

CVJ

0 25 The terminal 110 can be moved between the lower position and the operating position, for example, ό for installation or maintenance purposes. For example, moving from the lower position to the operating position i m is as follows:

Terminal 110 is raised from the lower position of Figure 2 so that

C/O

The pin 141a of the mounting frame 115 controls the lifting movement and moves from one end to the other end of the slide member 140a. In the same context, the terminal 110 also

CVJ

the pin 141a is rotated around the axis of rotation formed by the direction of the arrow 31 (Figure 3) as shown. When the terminal 110 is lifted and rotated in this manner, the projection portion 151a hits the tubular adapter 120 of the slot portion 160a as seen at the far end 161a from which it is inserted into the slot portion 160a. The terminal 110 is now moved or slid through its aperture of the space to be ventilated, at least partially above the ceiling horizontally towards the tube adapter 5 120. The projection 151a and the pin 141a control the horizontal movement of the terminal 110 and move in the slot 160a and slider 140a, respectively. The terminal horizontal movement is illustrated in Figure 4 by the arrow 41. The slot portion 160a together with the projection portion 151a prevents the vertical movement of the terminal, whereby the terminal cannot rotate about the axis of rotation formed by the pin 141a when the slot portion 160a 10 of the projection portion 151a. When the terminal 110 reaches the tube adapter 120, the terminal 110 is conveniently attached to the tube adapter 120 depending on the embodiment. A suitable seal (not shown) may be used for the attachment.

Moving the terminal 110 from the operating position to the lower position, for example for maintenance purposes, is effected, for example, as follows:

Initially, the terminal 110 is disconnected from the tube adapter 120. The terminal 110 is moved or slid horizontally away from the tube adapter 120. The projection portion 151a and the pin 141a guide the horizontal movement of the terminal 110 and move in the slot portion 160a and the sliding portion 140a respectively. The slot portion 160a together with the projection portion 151a prevents the vertical movement of the terminal, whereby the terminal cannot rotate about the axis of rotation formed by the pin 141a when the slot portion 160a of the projection portion 151a. However, when the projection portion 151a is
