OBJECT OF THE INVENTION The present invention is to be mainly applied to the technical field of air conditioning systems, in particular, those of the Split type and intended for domestic use.

BACKGROUND OF THE INVENTION

The problem of high consumption of the air conditioning units is not a new topic, for years there has been research on new techniques to mitigate, reduce or stabilize such consumption, developing technologies for energy saving, as it is the most recent case with "Inverter technology", designed with the purpose of increasing equipment efficiency.

Many technologies have emerged for increasing efficiency and effectiveness of refrigeration equipment, but the systems that all together represent an important part of the refrigeration load in many countries, the domestic air conditioners, of which the Split type is most popular, have not undergone major changes at a concept level. For example, energy saving algorithms or movement sensors, among others, have been developed, but the problem of having to cool an area (since the evaporating unit is next to the ceiling) when cooling is only required up to a certain height (the height of the people inside the area or in bed, at the moment of sleeping, for example) still remains.

Among the known solutions there is that from document US93831 15, describing a fresh air ventilation device adapted for use thereof with air conditioning (AC) apparatuses and / or heaters. In operation, the device supplements the recirculating air of the AC/heater with fresh air drawn from outside of the building. DESCRIPTION OF THE INVENTION

The main object of the invention refers to an adjustable vertical adapter for redirecting the cool air flow from the outlet of an air-conditioning apparatus such as a Split cooling unit, from its original upper position to a lower outlet position, and similarly relocating the hot air intake into a freely-adjustable position, either manually or automatically.

The present invention refers to a demountable and adjustable vertical adapter for Split air conditioning systems, intended to be fixed onto each Split evaporating unit in a room or premise, with the object of independently covering and redirecting the cool air outlet and the hot air intake.

The device of the invention comprises vertical ducts through which both coming out air (cool air) and that from the air intake (hot air) of the conditioning unit would circulate. Both independently.

The main object to be attained is to redirect the air flow in the outlet of the conditioning unit so that the cold air distribution takes place thorough the lower part of the room and not through the upper part thereof, that is, that the air coming out of the evaporating unit flows through this duct, up to the outlet air vents or diffusers at the bottom thereof, thus cooling the room.

Likewise, the object of the present invention allows relocating the hot air intake of the unit which is commonly placed at the upper part of the element, to another position being chosen by the user, all this through another duct similar to that of the cold air outlet, with the air intake being adjustable so that the user can place it as desired. The object of the invention can be adapted to the evaporating units of air conditioning equipment of the Split type which allow redirecting the cold air flow at the outlet of the conditioning unit with the purpose of distributing the cooled air from the lower part of the area.

Additionally, the hot air intake can be adapted, thus being possible to adjust the height at which the air intake takes place.

The main object is to be able to minimize the air turbulence at the evaporator outlet, thus causing the cold air to descend and be distributed more efficiently throughout the room, while the air intake adjustment causes that only the air in the area being between the cold air outlet and the air intake is cooled, thereby avoiding the rest of the area (between the air intake and the ceiling), thus increasing the system efficiency and reducing the energy consumption thereof.

PREFERRED EMBODIMENT OF THE INVENTION

As it can be observed in figure 1 , it shows a front view of the whole device object of the invention placed onto a Split air conditioner evaporating unit. It shows a first duct (1 ) which takes the cold air from the outlet of the evaporator and takes it downward up to an outlet being defined by an outlet (1 c) at the bottom. A second duct (2), similarly, causes the evaporating unit to take air through an opening (2c) which can be seen in the aforementioned figure at an intermediate height between the evaporating unit and the lower outlet (1 c) of the first duct (1 ), but with its height being adjustable by a fixing element (2d) using a pin or a screw type of fixing or any other technology having similar functionality.

As it can be seen in figure 2, it shows a front view of the first duct (1 ) which takes the cold air coming out of the evaporating unit and coming in through a first section (1 a), this being from the first duct (1 ). Consequently, the air follows a downward path through a first segment (1 b) of the first duct (1 ), until it goes out at the lower part through a first opening (1 c) of the first duct (1 ). As it can be observed in figure 3, representing an upper section of the first duct (1 ), it shows the running path of the first segment (1 b) of the first duct (1 ) which ends at a bend directing the cold air towards the first opening (1 c) at the bottom.

As it can be observed in figure 4, it shows the side view of the first duct (1 ) taking the cold air coming from the evaporating unit and directing it downwardly. It also shows the first section (1 a) which must be adjusted at the outlet of the evaporating unit, directing the air downwardly, passing through the first segment (1 b) which starts from said section, and coming out, finally, through an outlet (1 c) located next to the first segment (1 ) at the bottom thereof.

As it can be observed in figure 5, it shows a front view of the second duct (2) arrangement through which the air from the area will come in towards the air intake of the evaporating unit. The air comes in through the opening (2c), travels upwardly through a second section (2a) of the second duct (2), and flows, finally, towards the evaporating unit air intake through a second segment (2b) of the second duct (2). The vertical position or height of the opening (2c), may be adjusted using the fixing element (2d), being either manually or automatically actuated, which adjusts (or allows adjusting) the position of the second segment (2b) of the second duct (2), thus adjusting the height at which the opening (2c) is positioned.

As it is observed in figure 6, it shows an upper view of the second duct (2) through which the air from the area will come in towards the evaporating unit air intake. It shows the opening (2c), through which the air coming from the area will travel upwardly through the second section (2a) of the second duct (2), and will flow, finally, through the evaporating unit air intake through the second segment (2b).

As it can be observed in figure 7, it shows a side view of the duct (1 ,2) arrangement through which air going in the evaporating unit circulates. It shows the opening (2c) which acts as an air intake, directs the air through the second section (2a) segment until it reaches the evaporating unit air intake, which is surrounded by the second section (2b) segment. The element (2d) can be observed again, which will allow adjusting the height at which the opening (2c) is positioned.
