Definitions

  • the invention relates to a device for conditioning a structurally incomplete volume of space by means of a gas mass flow and their use.

  • a heating pipe is laid in each case, from the outlet slits warm air flows out.
  • the thawing walls have foldable aprons in their upper area, which rise under the influence of the upward flowing warm air and rest against the wagon side walls. Under the influence of gravity, these aprons fall back into their vertical starting position.
  • thaws are installed.
  • the main difference to the above-mentioned stationary structures is that the thawing tent can be completely removed and stored during the warmer months of the year. Nevertheless, even with the thawing tents, an enclosure for the entire vehicle is created.
  • the Auf- / /- the dismantling of such a thawing tent requires a not inconsiderable amount of time.
  • the thawing tents - especially during the winter - must be reliably secured against being torn off in stormy weather conditions.
  • a thawing tent also has the character of a stationary installation to which the rail vehicles to be treated have to be supplied separately.
  • the invention is therefore based on the object to provide a device for conditioning a structurally incomplete volume of space by means of a gas mass flow, which overcomes the disadvantages of the known prior art.
  • this device should be able to be used mobile and be suitable for use even in confined space conditions.
  • the device is formed of an array of inflatable air cushion, the arrangement consists of a main air cushion and at least one additional secondary air cushion, each sub-air cushion in one piece or cohesively with the formation of a pivotally movable intermediate element is connected to the main air cushion and each intermediate element Has at least one gas-permeable passage between the main and secondary air cushion, the device has at least one inlet opening for introducing a conditioned gas mass flow and at least one outlet opening with an opening in excess pressure in the air cushion outlet valve for discharging the gas mass flow, and the arrangement of main and secondary Air cushion is aligned in the inflated state such that each secondary air cushion angled aligned with the main air cushion and the at least one outlet opening on the inner side of the formed from the main and secondary air cushion in the inflated state angle is arranged.
  • an air cushion which when energized (ie filling) with air such and erects that a conditioning of the enclosing volume enclosing arrangement of main and secondary air cushion is provided.
  • This enclosure effect can be further enhanced by the fact that the device is designed such that not only several different air cushions of the same device against each other in the inflated state, but also create the air cushion to external, not to the device according to the invention associated objects with sufficiently smooth surface and In this way, a tight fit between auxiliary air cushion and external component can bring about.
  • the room volume to be conditioned can thus be largely sealed gas-tight against the ambient air.
  • the gas mass flow is introduced into the device via the at least one inlet opening and leaves it via the at least one outlet opening as soon as a sufficient overpressure has built up in the device according to the invention.
  • This built-in pressure in the device also serves to deploy or inflate the main and secondary air cushion.
  • the main air cushion has a plurality of outlet openings, which are executed for example in the manner of a perforated grid.
  • the effect of the automatic erection of the auxiliary air cushion can be enhanced by the fact that the sheaths of the intermediate elements are dimensioned on the inside in the inflated state side in terms of area smaller than on the outside.
  • the outer regions of the envelope expand more than the inner regions, which causes an automatic raising of the secondary air cushions with respect to the main air cushion.
  • a particular advantage of the invention is also to be seen in the fact that the volume of space to be conditioned is very small in comparison to the solutions known from the prior art, since the actual critical points are only selectively subjected to conditioning. This has a shortening effect on the required exposure time (ie the time that is effectively needed until the conditioning takes place) and on the energy efficiency as well as the C0 2 balance.
  • the invention is not limited to a conditioning of the space volume delimited by the device according to the invention by means of an air mass flow. It is rather the conditioning by means of any kind of gases possible.
  • air cushion takes place in the context of this application merely linguistic reasons and for ease of reading. It is obvious to the expert without saying that such an air pillow flows through not only by air but also from other gases and filled Kings ⁇ nen.
  • a first use of this technical teaching according to the invention provides for the enclosure and tempering of a corridor area of a vehicle arranged component. If, for example, the underfloor region of a rail vehicle is to be heated, then such a device according to the invention can be arranged in the space between the lower edge of the rail vehicle floor and the upper edge of the track area, wherein the depth or width of the main air cushion is approximately the width of the track or corresponds to the rail distance. To facilitate manual handling of the device, it can initially be stored in a folded state and placed under the rail vehicle. Only after correct alignment of the device with respect to the rail vehicle is this then transferred to a folded state, wherein in the unfolded state, the main and secondary pillows are fully deployed.
  • the main air cushion can either be a rather oblong cubic or
  • the secondary air cushion of the device according to the invention are directed such that the auxiliary air cushion fill the space between the vehicle and track and a conditionable air space - as a heating chamber - forms below the vehicle floor. In this way, for example, heated air can be introduced into this air space to heat or thaw mounted on the underbody of the rail vehicle components.
  • a useful further development of the inventive concept provides that main and / or sub-air cushion on their respective outer surfaces via locking elements for mutual hooking in the inflated state with adjacent main or secondary air cushion have.
  • the dimensional stability of the device according to the invention is improved and the seal between the air cushion even in unfavorable external conditions, especially in stronger wind or draft guaranteed.
  • these locking elements are designed as Velcro fasteners. These can be readjusted by an operator and corrected if necessary.
  • these locking elements are designed as locking strips with a sawtooth-like surface profile on the surfaces of the outer shells of the air cushion. In this way, the outer surfaces entangle upon the ingress of air, i. with unfolding air cushion, against each other automatically. A manual intervention by operating personnel is eliminated.
  • the device has at least one secondary air cushion, which is connected to form an articulated movable intermediate element with the end face on at least one longitudinal end of the main air cushion.
  • the main air cushion on the outer side of the angle formed by the main and secondary air cushions in the inflated state is equipped with stiffening stabilizing elements.
  • This may be, for example, in act the outer wall of the air cushion incorporated rigid fabric strips.
  • the outer side of the main air cushion can also be glued to a stiffening element (eg in the form of a plywood board) whose outer contour is adapted to the base area of the main air cushion.
  • the invention expediently provides that the outer geometries of main or auxiliary air cushions in the inflated state have recesses for collision-free adaptation to obstacles located in the room volume to be conditioned.
  • This embodiment variant is helpful if the object to be conditioned can not be completely enclosed by the device according to the invention.
  • the above-mentioned "axle walls" have a T-shaped outer contour, so that free spaces for the disc wheels of the rail vehicle are formed on both sides of the formed by the T-shape of the longitudinal web.

  • the gas-permeable passage in the intermediate element between the secondary and main air cushion has a pressure-dependent inlet valve. In this way it is ensured that in the course of filling the device according to the invention with a gas mass flow the overflow into one of the secondary cushions takes place only when a minimum pressure level in the main cushion is reached or exceeded. Thus, it can be ensured that the secondary cushions are filled with gas only when the main cushion has reached a sufficient basic stability. By using valves with different triggering limits, even the order of filling the various secondary pads can be specified.
