Description

AIR CONDITIONING APPARATUS

TO BE MOUNTED ON A WINDOW

  The present invention relates to an air conditioning apparatus

  station intended to be mounted on a window, and it aims more

  particularly a construction of such an air conditioning apparatus

  which improves natural lighting in the room

  in which said device is installed either, in an

  or similar, either in an office, or even in

a room for industrial use.

  Generally, an air conditioning unit intended to be mounted on a window comprises an assembly comprising at least one heat exchanger, an evaporator, means of

  supply or ventilation, as well as a set of conden-

  sation suitably mounted on the front or rear part of a container of rectangular profile, the upper and lower side or right or left side of one of its front faces forms the inlet or air suction means towards the interior of the room, while another front face forms the means for discharging cooled air towards

inside the premises concerned.

  However, a packaging device of the rec-

  tangular as described above occupies an important part

  aunt of the section of the window on which it is mounted, so that the window area supposed to provide natural light to the room in question is greatly reduced. This results in undesirable conditions in that the interior of the room in question is poorly lit or even darkened, and in that the user of said room is also subjected to the noise produced.

  by the air conditioning unit during operation.

  To improve the natural lighting conditions of the room in question, it has been proposed, in order to clear the useful surface of the window concerned, to mount the air conditioning unit on a wall partially excavated for this purpose, to thereby clear the window of any obstruction. However, this solution is not advantageous, since it is very expensive and it implies the need to damage the structure of the building concerned. In order to improve the natural lighting conditions and

  of noise pollution described above, the body of the device

  The air conditioning unit is divided into an indoor unit and an outdoor unit. The indoor unit is intended to be mounted on any part of the interior wall of the room concerned, except on a window; therefore, it does not

  does not interfere with the natural lighting of the room; however, this agency-

  The disadvantage is that it is relatively expensive.

  American patent US-A-4 109 708 describes an apparatus for

  typical air conditioning. This known device includes comparisons

  elements arranged so as to ensure accessibility and cooling of the engine, a vertical partition in the shape of an "L" delimiting, in the casing of said air conditioning unit,

  a condenser compartment with an additional air inlet

  mental and an air circulation channel; a panel of this partition carries the drive motor for the evaporator fan. An inspection door opposite the partition panel allows the entire assembly to be dismantled for maintenance purposes and to make other parts of the appliance accessible. The latter is easy to maintain without having to dismantle the top wall. However, this prior patent does not mention the division into an indoor unit and an outdoor unit by a partition delimiting compartments,

  so it’s just an air conditioning unit here

  tisation of the rectangular profile type.

  The object of the present invention is therefore to propose an air conditioning device intended to be associated with a window, which makes it possible to improve the natural lighting conditions of the room concerned and to reduce the noise caused by the

device operation.

  Another object of the invention consists in creating an air conditioning device associated with a window, the body of which is subdivided into an indoor unit intended to be mounted on the window and an outdoor unit intended to be mounted on an outer wall. The apparatus according to the present invention comprises an indoor unit comprising a fan and an evaporator, as well as an outdoor unit comprising a condenser, a compressor and cooling means, the two units

being separated by a partition.

  According to the invention, the part forming the air inlet on the indoor unit and the part forming the air outlet on the outdoor unit for discharging the air, after heat exchange, towards the interior of the room concerned are mounted. at the level of the window, so as to extend forward from the upper part of the thin casing of the air conditioning unit, and the active part comprises a condenser, a compressor and cooling means arranged in the lower part of the casing, this active part being mounted on the outer face of the window, which allows

  improve the natural lighting conditions of the indoor space

tightened.

  Other goals, characteristics and appaial advantages

  will read the description of various modes of zeali-

  sation of the invention, made without limitation and with reference to the appended drawing, o:

  - Figure 1 shows, in cross section, the agen-

  cement of the air conditioning apparatus according to the present invention, and - Figure 2 shows another embodiment of the invention. The figures show an air conditioning unit for conditioning the air inside an enclosure or a room.

  As shown in Figure 1, the air conditioning unit

  This comprises a casing 1 which contains an evaporator 2, a condenser 3, fan means 4, a compressor 5 and cooling means 6, like a conventional air conditioning unit. Housing 1 has a "T" shape

  and is subdivided into an upper part and a lower part

  by an intermediate plate or partition 15. The part

  upper extends forward from the lower part

  lower of the casing 1, and it is provided with a relatively thin inlet 7 and outlet 8, and two air passages are formed there by a partition 16 arranged between the inlet 7 and the outlet 8. The evaporator 2 has a height equal to that of the entrance 7 and is arranged near the interior of the room to be air conditioned. The fan means 4 are arranged at a certain distance from the window and extend over the

  two passages, so as to draw in the indoor air through the

  port 7 and to discharge the conditioned air (that is to say the air which has undergone a heat exchange) inwards through the outlet 8. The part extending from the casing 1 has

  a length greater than the thickness of the building wall 9.

  The evaporator 2 has a height less than that of the upper assembly constituting an evaporator assembly. Because the evaporator 2 according to the invention has a height and therefore a relatively small heat exchange surface, its thickness (or depth) is relatively large for

  compensate for the small frontal heat exchange surface.

  The lower part of the casing 1 is mounted at a

  distance from window 10 of the room considered. In this lower part are conveniently arranged the condenser 3,

  the compressor 5 and the cooling means 6, consisting of

  as a whole, killing the active operating means of the apparatus. Thanks to this arrangement, the noise due to the operation of this device and transmitted to the interior of the

  air-conditioned room is greatly reduced.

  The evaporator 2 and the condenser 3 are mounted respectively

  tively on the upper and lower parts in order to allow the condensed water formed by the evaporator 2 to flow downwards, towards the condenser 3, which

  increases the condensing efficiency of the device.

  For the installation of the air conditioning device described, the lower part of the casing 1 is fixed, for example, on the wall 9, using support and spacing elements 12, such as bolts, nuts or the like. Housing 1 is supported

  by a plate 14 carried, in turn, by a support element

  port 13, one end of which is mounted on the wall 9. The inlet 7 and the outlet 8 defined by the upper part of the casing 1 pass through the window 10 so as to be placed inside

laughter of the air-conditioned room.

  As shown in Figure 1, the housing 1 of the device

  reil air conditioning is mounted on the outer wall of the wall 9, the inlet 7 and the outlet 8 being placed inside the room, so that the air conditioning unit is partially mounted on the window 10, which causes a

  improvement of the natural lighting of the premises concerned. The en

  seems to generate cold 11 comprising the compressor 5, the cooling means 6 and the condenser 3 is disposed outside the room, so as to reduce, inside said room, the noise caused by the operation of

  the device which is therefore constituted by a climatic device

  with an indoor unit and an outdoor unit

  better. FIG. 2 shows another embodiment of the present invention, in which the functional assembly 11 is mounted in the upper part of the casing 1, and is fixed to a wall 9, at the top of the window 10, using a way to

suspension 12.

  As explained above, according to the present

  invention, the entry and exit of the air conditioning

  tion defined by the upper part or by the lower part

  lower extends towards the front of the casing 1, in the form of a thin part, and the lower part of the casing, which contains the active assembly generating cold or heat, is mounted outside the premises concerned . Thanks to this arrangement, the invention makes it possible to reduce the surface or the volume required for the installation of the air conditioning apparatus, to improve the natural lighting conditions of the room and to reduce the

  noise pollution due to the operation of the device.

  If the air conditioning unit according to the invention

  tion would be used for heat pump heating purposes the respective positions of the evaporator 2 and the condenser 3 would be reversed to inject into the room the air heated by the condenser 3 but the principles of

the invention would be preserved.

  Of course, the present invention is not limited to the embodiments described and shown, but it is capable of numerous variants accessible to man of

  art without departing from the spirit of the invention.
