Description

i 2819880 The present invention relates to an air conditioning unit

  or air conditioning intended to be placed in an unobstructed position from the walls in a room with a climatic atmosphere to be controlled, in particular a cellar room used as a storeroom. Air conditioners are known which are in the form of two separate blocks, one inside the enclosure to be air conditioned, this first block containing the air conditioning function and the refrigeration unit, and the other block placed outside. , often fixed to the wall, performing the evacuation of the calories drawn

in the room.

  In general, the air conditioners of this

  type have various disadvantages.

  First, the physical separation into two blocks requires having two suitable locations and involves fairly expensive laying and installation work with holes and fixing of connecting conduits. In addition, the condenser block mounted outside, cannot be installed everywhere because the place must be clear, not very sunny and discreet

  so as not to degrade the aesthetics.

  Due to the distance of the two blocks, the connecting conduits can reach significant lengths detrimental to the overall performance of the installation and even to the proper functioning of the assembly. For all these reasons, this type of air conditioner is not a technically and economically suitable solution for creating an atmosphere

  ideal in a cellar and in particular a wine cellar.

  We also know of compact air conditioners to be integrated into a wall. Through one side of the device, the air conditioning comes out and the calories are

  rejected to the outside by the opposite face.

  This type of device seems attractive by its

2 2819880

  perfect integration into the wall or wall and therefore only represent a less technical and aesthetic discomfort for the environment. Unfortunately, these qualities are greatly diminished by various disadvantages. The compact nature of this device increases its cost price. Indeed, its assembly of production turns out to be longer and more difficult and the regrouping of functions leads to choices

  and more expensive components.

  In addition, its installation requires the use of an exterior wall or a common wall with a room or a room of large volume due to the rejection to the outside and the necessary evacuation of calories

extracted.

  The part linked to the installation in the overall cost of this type of air conditioner turns out to be high due to the technical work relating to the structures

of the building.

  The object of the present invention is to remedy

  to various of the aforementioned drawbacks.

  It relates to an air conditioning unit for a room or a room, in particular a wine cellar, intended to be placed in a position free from the walls. The device includes two functional blocks corresponding to the basic functions grouped in an independent box simply supported or placed in a place clear of the walls inside the room or enclosure whose installation and installation costs are reduced. and whose compactness and independence allow it to be placed almost anywhere in

  inside the room or enclosure.

  To this end, the air conditioning or air conditioning apparatus according to the invention consists of two functional blocks each corresponding to a main function either evaporation or condensation, the blocks being grouped in a box

3 2819880

  thermally insulating and independent of a method of fixing or installation. The hot air is evacuated from the condenser to the outside by a flexible aeraulic connection of the ventilation duct type, and the condenser is crossed by a flow of fresh air coming from the outside through an aeraulic connection.

  Many advantages therefore appear.

  The work and cost generated by installation and installation are reduced. The installation is not linked to the constraint of a particular location or of a laying technique and is limited to the installation and connection of the air ducts opening to the outside or in a technical exhaust duct existing. For these connections, it suffices to cross one of the walls or the wall. In recent buildings or places of accommodation, reservations suitable for this purpose exist. It is enough

  then simply make the connection.

  Thus, this type of connection makes it possible to confer a mobile or displaceable character to the device according to the invention and therefore an independence in the choice of

his location.

  Other features and benefits of

  the invention will appear in the description which follows,

  given by way of example and accompanied by the drawings which represent: FIG. 1: a schematic overview of the installation showing the cellar room and the air inlet and outlet on the air circuit removing calories from the condenser; Figure 2: a simplified perspective view of the air conditioning apparatus according to the invention seen from the side showing its general constitution, view in which the box is shown transparent and the turbines are placed at the front for reasons of clarity.

  The air conditioning device according to the invention is provided more particularly, but not limited to, for a cellar, in particular a cellar room 1 in which must exist and maintain precise climatic ambient conditions, for example a humidity level. and an air temperature

as constant as possible.

  In the case of a wine cellar constituting one of the applications of the invention, the following approximate values may be indicated: humidity level: 70% air temperature: 12 C allowing bottles of wine to be stored as well as possible

  2 stored, for example, on supports 3.

  This interior atmosphere is created and can be guaranteed by means of an air conditioning device 4 according to the invention making it possible to condition the ambient air in terms of humidity and temperature to the

  desired values for the intended application.

  The admitted air can be filtered on the aeraulic circuit and if necessary treated against insects, mosses, fungi and other parasites. The air conditioning unit 4 according to the invention consists of two compact functional blocks or sub-assemblies 5 and 6 corresponding to the two main basic functions, namely an evaporative block 5 and a condensing block 6 of a refrigerant. allowing after compression and expansion to transfer the calories between two batteries 7 and 8 respectively from the evaporator

and condenser.

  These sub-assemblies 5 and 6 are grouped together and enclosed in a box 9, a trunk or other thermally insulating container in order to produce a compact and movable unit without any particular constraint or

  location, neither support, nor fixing, that is

2819880

  say totally independent of configuration and

the conformation of the place.

  Of course, this box 9 can simply be divided into two specific compartments 10 and 11 each provided for one of the two basic functions of the air conditioning unit 4 according to the invention, namely the evaporator function and the condenser function. from a refrigeration unit 12 comprising a compressor, an expansion valve and a reserve of refrigerant to form a machine

  refrigerator used as an air conditioner.

  The evaporation function is materialized by the evaporator battery 7 giving the air flow which passes through it precise climatic characteristics, for example a temperature and a hygrometry adapted to the application. The condensation function is materialized by the condenser battery 8 through which an air flow is responsible for removing the calories from the interior medium in which the evaporator battery 7 is immersed by thermal transfer using the change in physical state of the refrigerant. The medium in which the battery 7 of the evaporator is immersed is, for the application envisaged, the part

cellar 1 for cellar use.

  The air flow circuit of the evaporator is a short circuit inside the box formed for example by a simple air inlet 13 equipped with an openwork protection 14 and possibly a filter upstream of the battery 7 of the evaporator, and a simple air outlet 15 downstream of the evaporator battery also protected by an openwork piece 16. This air circuit is a channel 17 inside the first compartment 10 of the box 9, straight or at right angles, of which the section is occupied by the battery 7 of the evaporator. To improve the exchange speed, it is planned to project the air flow onto the battery 7 of the evaporator via a turbine 18

6 2819880

  taken from outside the device. After passing over the evaporator battery, the air conditioning flow

  leaves the casing 9 on the front by the air outlet 15.

  The second compartment or condensation compartment 11 of the box 9 is connected aeraulically to the outside of the room by the aeraulic circuit of the condenser which is a two-branched heat evacuation loop 19 and 20 leading to the interior volume of the compartment 11 containing the condensing battery 8. Each end of this exhaust loop is in communication with the outside environment of the room to be conditioned through a wall or a wall 21 by air inlet 22 and air outlet 23 vents each equipped with a grid. It is an aeraulic heat evacuation circuit having an external part along the two branches 19 and 20 in the form of two aeraulic conduits, for example two flexible ducts one upstream 24, the other downstream 25 and an internal part to the box 9, straight or bent in the form of a channel 26, the passage section of which is closed by the battery

8 of condensation.

  The upstream sheath 24 is connected to the casing 9 by a piece of cuff 27, the rear part of which

  contains a dust filter 28.

  To increase the speed of the air exchange at the level of the condenser battery 8, provision is made to create a forced discharge flow by a turbine 29 sucking in and projecting the fresh outside air.

  on the upstream face of the condenser battery 8.

  In the basic version there is an evaporator turbine 18 and a condenser turbine 29 each placed near the exchange battery

  corresponding respectively 7 and 8.

  As a variant, the aeraulic circuit of the conditioned or conditioned air can be supplied with air coming from outside before or not

7 2819880

  lowered in temperature by an additional air duct or duct coming from an outside air inlet fitted with a dust filter (variant not shown). The side looking towards the inside of the device is that on which the fresh air is projected, the outside face forms the air outlet of the device from which the flow of conditioned air is ejected. More particularly, the heat removal circuit has an upstream branch 19 coming from the air inlet outside the room furnished with a grid and a filter integrated in the separation wall. This upstream branch 19 is produced in the form of a flexible sheath 24 connecting the air inlet to the box in the condensation compartment 11 from which it opens onto the turbine equipping the upstream face of the condensation battery 8. The transfer of calories is carried out by the refrigeration circuit and the transmission of these then their evacuation by means of the condensing battery 8 and

a connection to the outside.

  This connection to the outside is the downstream branch 20 of the evacuation circuit starting from the condensation compartment 11 of the box 9 to lead to the outside by an evacuation mouth 23 also equipped with a protective grid and optionally a filter. This connection is produced in the form of a flexible air duct 25 making it possible to connect the outlet of the box 9 to the assembly without difficulty.

  air outlet 23 outside the room.

  Evaporator condensates are evacuated to the sewer or collected in an occasionally emptied tank and possibly collected for all

  uses requiring demineralized water.

  The general operating conditions are such that icing on the evaporator battery is minimal. We can provide for this purpose

8 2819880

  if necessary, a reverse cycle operating mode or a small auxiliary heating device intended for the evaporating coil or an operating mode in which a temporary stop is commanded at each occurrence of frost. The installation of the air conditioning apparatus according to the invention does not require major work. It suffices to provide the air inlets and outlets and the air connections. In general, the air conditioning circuit is short because it operates on ambient air. In order to ensure the minimum renewal of the ambient air, it will suffice to provide several inlets

  of small section air distributed in the room.

  It can thus be placed in any part of the room, without any constraints related to installation or installation. We prefer a clear place at a certain distance from the walls for a

better air distribution.

  The air conditioning apparatus according to the invention can be associated with other air treatment functions ensuring its sterility, its purification, its chemical neutrality, its dusting and others. It suffices to provide in series the appropriate additional module or an injection nozzle into the air flow of a treating, disinfecting, fungicidal product,

  insecticide or other means or product.

  It is understood that apart from the strict application in a wine cellar, the device according to the invention can be used in any closed room requiring the maintenance of a particular climatic atmosphere.
