Definitions

  • the invention relates to an air conditioner with at least one inlet outlet opening to the room to be air-conditioned and relates in particular to such an air conditioner for work, living or lounge rooms or for vehicles, in particular motor vehicles.
  • air conditioning devices are conventionally used in one of the walls delimiting such a room, which suck in fresh air from the outside environment, condition it, ie to a be bring the right temperature and / or relative humidity, and then deliver a more or less closable outlet grille into the room to be air-conditioned, usually with an adjustable sealing element, such as a folding blind or the like.
  • This conventional type of air conditioning has u. a. the disadvantage that the outflowing fresh air tends to cause disturbing noise or rattling noises.
  • the most important disadvantage of this known type of room air conditioning is the fact that the fresh air emerges from a relatively small area of the outlet grille of the air conditioning unit relative to the wall surfaces of the room to be air-conditioned and therefore not only uncomfortable, but in many respects also extremely harmful to health Brings draft effect, which also leads to undesirable air flows and turbulence, especially when the air conditioner is running, which inevitably mixes and swirls the air in the room to a greater or lesser extent with existing dust, which in turn further deteriorates the indoor climate.
  • the invention is therefore based on the object to provide a way to improve conventional air conditioners for work, living or common rooms as well as for vehicles of the type described with simple and inexpensive and otherwise practically inexpensive means so that such rooms while avoiding the disadvantages of these conventional air conditioners both with original equipment and by means of retrofitting simple, quick and convenient and yet extremely economical warm or cold air with or without predetermined (r) relative (r) humidity can be supplied or removed without any dangers for Noise or draft-related nuisance or even damage to health would be to be feared, rather, while avoiding the development of dust at the same time, significantly improves the room climate and thus the comfort of people, animals or plants present in such rooms as well as sensitive machines such as computers, both when heated and can also be increased considerably when cooling such rooms.
  • the conditioned air is supplied or withdrawn from the conditioned air via one or more surfaces (s) which are as large as possible in relation to the air outlet opening (s) of the air conditioning unit, but in doing so the Bringing the outflow speed of the same to the lowest possible value, or keeping it there, is shown by the invention a way not only to meet these conditions and both the initial equipping of a room of the type described with a climate device to enable according to the invention, but also in such rooms already installed air conditioners by way of retrofitting with an appealing aesthetic external appearance of both the air conditioner and the room to be air-conditioned with this so that not only the disadvantages of conventional air conditioners described, in particular Noise nuisance and disturbance of the feeling of comfort and sometimes also of health due to draft and / or swirling air as well as with regard to the production costs can be effectively avoided.
  • the calming chamber can have a guide device in its interior, for which otherwise at least one hood-fixed partition wall can preferably be arranged in the interior of the calming chamber, which, in further perfection of this subordinate inventive concept, is made of sheet metal or plastic sheet material or but can also be formed as a one-piece plastic injection molded or pressed part.
  • a further perfection of this subordinate inventive concept of the same aims, according to which the partition wall or walls can have a roughened surface (s) applied, for example, by a rubber or plastic coating. Because of this, flow energy is at least in the boundary layer of the fresh air emerging from the air outlet opening of the air conditioner, at least in the boundary layer, such that the fresh air supplied to the large-area outflow throttle has a particularly low flow velocity as the inflow velocity.
  • the invention is fundamentally aimed at achieving an air supply to the room to be air-conditioned with a minimal inflow speed into the room, it may be desirable if, in addition to the supply of fresh air into this room as well a certain drafts effect, which is then checked for harmlessness to health, remains noticeable, in order to give the occupant the feeling of fresh air at all, possibly combined with a certain feeling of cooling, without significantly disturbing the level of comfort he initially achieved compared to conventional air conditioning units would.
  • the invention provides, according to another subordinate inventive concept, that an approximately slit-shaped flow accelerator nozzle which can be brought into effect is arranged in the calming chamber. Experience has shown that this can advantageously be arranged in the upper region of the calming chamber.
  • the accelerator nozzle is arranged in the uppermost air duct of the guide device.
  • This accelerator nozzle should not fundamentally accelerate the supply air flow, which has been calmed down by the concept according to the invention, in its entirety, but rather, while maintaining the greatest possible infiltration condition of the supply air into the room to be air-conditioned, only in a targeted manner at certain points which are particularly felt by the occupants low proportion of fresh air with increased speed give the impression of the presence of fresh air supply.
  • the flow accelerator nozzle can be designed in any form, and also in the form of a plurality of nozzle openings of relatively small outflow cross-section, or as a slit-shaped nozzle that covers all or only part of the width of the settling chamber, it has been found Proven particularly useful for design as well as manufacturing reasons, if the accelerator nozzle is formed by two hood-fixed walls made of sheet metal or plastic, which enclose a converging space between them in the direction of the outflow throttle.
  • Such an embodiment also has the additional advantage that it is relatively a small outflow space, a noticeable drafts flow can be achieved, and this with a relatively small amount of supply air, while the majority of them infiltrate the remaining large areas of the outflow throttle into the space to be air-conditioned at minimal speed in a manner that is calmed according to the invention.
  • the accelerator nozzle can have a closure element, which can be actuated from outside the hood, for its inflow opening.
  • This can furthermore advantageously be formed by a flat or curved plate which is articulated on the hood side and is preferably steplessly pivotable on the hood side for pivoting from a closed position closing the inflow opening of the accelerator nozzle into an open position opening this inflow opening for air entry. It can be seen that this creates the desired possibility of being able to individually satisfy the feeling of comfort by virtue of the fact that, at its own discretion, by actuating the closure element of the accelerator nozzle, the outflow speed from the latter and thus also the exit speed of the area of the outflow throttle assigned to it or adjacent to it Supply air can be set.
