Definitions
- the invention relates to a method for manufacturing an air- conditioning system closing plate, the method comprising manufacturing a support structure with an opening having a first sealing surface and arranging in the opening a turnable baffle having a second sealing surface and being turnable to a closed position, in which the turnable baffle is arranged to substantially entirely close the opening and in which the second sealing surface of the baffle is arranged to at least partly touch the first sealing surface of the opening and to at least partly seal a gap between the first and second sealing surfaces.
- the invention also relates to an air-conditioning system closing plate that comprises a support structure with an opening having a first seal- ing surface and in the opening a turnable baffle having a second sealing surface and being turnable to a closed position, in which the turnable baffle is arranged to substantially entirely close the opening and in which the second sealing surface of the baffle is arranged to at least partly touch the first sealing surface of the opening and to at least partly seal the gap between the first and second sealing surfaces.
- a problem with such a closing plate is the tightness between the baffle and support structure and how to make a closing plate, in which the baffle and support structure can together form such a tight structure that prevents fire gases and the like from spreading in the air-conditioning system.
- Another problem is the fastening of the sealing between the first and second sealing surfaces to the baffle.
- the sealing is mounted between two parts that are pressed together.
- the prior-art solutions therefore always require at least two parts for mounting the sealing. This is a specific problem if the manufacturer makes a great deal of closing plates with different sizes. Different-sized closing plates require different-sized parts and this multiplies the number of required parts. In addition, the joining of the parts takes time.
- One advantage of the solution of the invention is that the second sealing surface can be made to exactly match the first sealing surface. This results in a tight structure when the baffle is in its closed position. In addition, only a little time is needed to make the baffle, because the sealing is mounted in a groove. This reduces the number of required items by at least half, because the sealing is not mounted between two parts.
- the sealing groove is easy to make while the second sealing surface is machined in the same machine tool, for instance.
- the closing plate of the invention can therefore be made with a smaller number of work stages than the conventional closing plate.
- the second sealing surface of the baffle can easily be streamlined using machining, in which case the pressure loss caused by the baffle is small when the baffle is in the open position shown in Figure 2, for instance. Pressure loss occurs, because the baffle is in the airflow passing through the opening of the closing plate.
- the baffle causes turbulence in the airflow, for instance. It is also possible to affect the sound level by means of the shape of the second sealing surface. The baffle causes sound when it is in the airflow. Machining the second sealing surface of the baffle to be streamlined and to cause less turbulence also reduces the sound level caused by the baffle.
- a drilling for a shaft can also preferably, but not necessarily, be machined to the edge of the baffle. More preferably, but not necessarily, two drillings are machined to the baffle, one drilling diametrically on each side of the baffle. Each drilling preferably, but not necessarily, comprises a bottom.
- a spring can then first be placed in each drilling and after this, a shaft.
- the baffle can be mounted in place in such a manner that the baffle is mounted on the support structure having recesses for the shafts and the baffle is positioned so that the shafts installed in the drillings are at the location of the recesses, as a result of which the springs placed in the drillings push the shafts to the recesses. Drillings of this type are easy to make while the second sealing surface of the baffle and the groove are machined.
- Figure 1 is an air-conditioning system closing plate in a situation, in which the baffle is closed
- Figure 2 is an air-conditioning system closing plate in a situation, in which the baffle is open
- Figure 3 shows a circular baffle
- Figure 4 is a rectangular baffle
- Figures 1 and 2 show an air-conditioning system closing plate that comprises a support structure 1 with an opening (not marked with a reference number) having a first sealing surface 2.
- the air-conditioning system closing plate also comprises a turnable baffle 3 having a second sealing surface 4.
- the turnable baffle 3 can be turned to a closed position, in which the turnable baffle 3 is arranged to substantially entirely close the opening and in which the second sealing surface 4 of the baffle 3 is arranged to at least partly touch the first sealing surface 2 of the opening and to at least partly seal a gap 5 between the first sealing surface 2 and the second sealing surface 4.
- first sealing surface 2 and the second sealing surface 4 refer to the surfaces that are arranged to settle against each other when the baffle 3 closes the gap of the support structure 1.
- the baffle 3 and the opening can have any cross-profile shape. For instance, Figure 3 shows a circular baffle 3 and Figure 4 shows a rectangular baffle 3.
- the second sealing surface 4 of the baffle 3 is at least partly machined to match the first sealing surface 2 of the opening.
- FIG 4 which shows a rectangular baffle 3
- the second sealing surface 4 of the baffle 3 is straight.
- the figures show baffles 3 that are turnable around a shaft 6 in the middle of the baffle 3 in such a manner that on both sides of the baffle 3, there is a second sealing surface 4 arranged to settle against the first sealing surface 2 of the opening.
- the cross-profile of the second sealing surface 4 is partly curved, because it is made to match in cross-profile the first sealing surface 2 that is curved in cross-profile.
- the first sealing surface 2 and the second sealing surface 4 can alternatively have another matching cross- profile shape.
- Figures 1 and 2 show a support structure 1 that is a casing part and comprises elements for connecting the closing plate to other components (not shown) of the air-conditioning system.
- An air-conditioning duct (not shown) can be such a component.
- the baffle 3 can at least partly be made of a ceramic material or calcium silicate.
- a groove 7 for a sealing material 8 can also be machined to the baffle 3, the sealing material 8 being arranged to at least partly settle between the baffle 3 and support structure 1 when the baffle 3 is turned to its closed position.
- a drilling 9 for the shaft 6 can also be machined to the baffle 3, the baffle 3 being turnable around the shaft 6 to its closed position.
- the invention also relates to a method for manufacturing an air-conditioning system closing plate.
- a support structure 1 with an opening having a first sealing surface 2 is manufactured.
- a turnable baffle 3 having a second sealing surface 4 is arranged in the opening, the turnable baffle 3 being turn- able to a closed position in which the turnable baffle 3 is arranged to substan- tially entirely close the opening and in which the second sealing surface 4 of the baffle 3 is arranged to at least partly touch the first sealing surface 2 of the opening.
- the second sealing surface 4 of the baffle 3 is machined to at least partly match the first sealing surface 2 of the opening.
- the baffle 3 can be at least partly manufactured from a ceramic material or calcium silicate.
- a groove 7 for a sealing material 8 can also be machined to the baffle 3, the sealing material 8 being arranged to at least partly settle between the baffle 3 and support structure 1 when the baffle 3 is turned to its closed position.
- a drilling 9 for a shaft 6 can also be machined to the baffle 3, the baffle 3 being turnable around the shaft 6 to its closed position.
