Description

Title of the invention: AIR CONDITIONING DEVICE Scope of the invention

[0001] The present invention relates to an air conditioning device, in particular for air treatment in indoor spaces. Context of the invention

[0002] Air conditioning large spaces continues to present difficulties today in guaranteeing the thermal comfort of its occupants.

[0003] Displacement diffusion systems are known to have limitations in high-temperature environments, and these displacement diffusion systems can be combined with other mixing diffusion systems, such as long-range nozzles to support the first system when it is not sufficient.

[0004] The systems mentioned are air distribution solutions that must be part of an air conditioning installation that supplies the treated air produced in an air handling unit, through ducts to the diffusers. This is what is known as centralized air-to-air air conditioning.

[0005] There are innovations which aim to solve or improve the diffusion problem, as described, for example, in document EP1318360A2, but they do not consider air conditioning, but only diffusion.

[0006] On the other hand, there are air-water systems in which there are equipment such as fan coil units which are equipped with a fan and an air exchanger and which condition the air of the room where they are installed by means of forced circulation of air through the exchanger by fan.

[0007] These devices have lower operating costs, since instead of moving air, they move water, which has a higher specific heat capacity, and with a smaller fluid volume, the same energy can be supplied. These fan coil units are generally connected to a single air distribution system. Description of the invention

[0008] Therefore, an objective of the present invention is to propose an air conditioning device, in particular for air treatment in interior spaces, which allows the treatment of large spaces, located directly in the area to be treated, and which allows the air conditioning of both the space immediately adjacent to the equipment and areas distant from it.

[0009] The air conditioning device of the invention makes it possible to overcome the aforementioned disadvantages while presenting other advantages which will be described below.

[0010] The air conditioning device according to the present invention is described in claim 1, and the dependent claims include additional features which are optional.

[0011] Thus, the air conditioning device according to the present invention comprises an air inlet, fans, a plurality of air outlets, and a controller. The air conditioning device is characterized in that it comprises first and second modules, wherein the air inlet is common to both modules, and wherein the first module comprises a plurality of first air outlets and the second module comprises a plurality of second air outlets. The controller determines the air outlet solely through the first outlets, solely through the second outlets, or through both the first and second outlets simultaneously.

[0012] And optionally: • the first outlets are located on a lower part of the air conditioning unit and the second outlets are located on an upper part of the air conditioning unit; • the air inlet is located on the upper part of the air conditioning unit; • the first air outlets define a 180° arc; • the second air outlets define an arc between 225° and 360°; • the second air outlets are nozzles; • the first air outlets are displacement diffusers; • the device includes two silencers; • each of the first and second modules includes a heat exchanger; • the device also includes a filter common to the first and second modules; • Each of the first and second modules includes a suction temperature sensor and a blowing temperature sensor; and / or • the device also includes a pressure switch in the filter common to the first and second modules.

[0013] In particular, the air conditioning device comprises first and second modules, each of which includes an air inlet common to both modules, a filter, fans, two silencers, a heat exchanger coil or heat exchanger with a condensate recovery tray, and air outlets. It also includes a controller, as well as temperature and pressure sensors or probes necessary for independently controlling the supply air temperature of each outlet. It also allows for the supply of air by the first exits only, by the second exits only, or by the first and second exits at the same time.

[0014] In this way, we obtain an air conditioning device, particularly for large interior spaces, which is very versatile, since it can operate in three different modes, depending on the needs.

[0015] Preferably, the first outlets are located on a lower part of the air conditioning device and the second outlets are located on an upper part of the air conditioning device.

[0016] In addition, the air inlet is preferably located on the upper part of the air conditioning device.

[0017] According to a preferred embodiment, the first air outlets define an arc of 180°, and the second air outlets define an arc between 225° and 360°, although they can define any other suitable arc.

[0018] Preferably, the first outlets are displacement diffusers and the second air outlets are long-range nozzles.

[0019] In addition, each of the first and second modules preferably includes a silencer, a heat exchanger, a suction temperature sensor and a blowing temperature sensor, as well as a pressure switch in the suction filter common to the first and second modules.

[0020] The air conditioning device also preferably includes a filter common to the first and second modules.

[0021] The air conditioning device according to the present invention offers, among other things, the following advantages:

[0022] - it provides two separate diffusion systems;

[0023] - it combines a displacement diffusion system with a diffusion system long-range and high-induction nozzles;

[0024] - it can be placed directly in the occupied area, thus reducing distances and the ranges to be covered by the diffusers and, consequently, the air conditioning is ensured more efficiently. Brief description of the drawings

[0030] Fig. 1 represents an air conditioning device according to the present invention which comprises first and second modules (1,2) placed side by side.

[0031] The air conditioning device includes an air inlet (3) which is common to the first and second modules (1,2), and the first module (1) includes a plurality of first air outlets (4), and the second module (2) includes a plurality of second air outlets (5).

[0032] Said air inlet (3) is located on the upper part of the air conditioning device. As for the first air outlets (4), they are located lower than the second air outlets (5), as can be seen in the figures.

[0033] According to a preferred embodiment, the first air outlets (4) are orifices or displacement outlets and define an arc of 180°, while the second air outlets (5) are nozzles and define an arc between 225° and 360°, depending on their installation location.

[0034] The first outlets, which ensure diffusion by displacement, directly treat the occupied space at ground level, and the second outlets, which, according to the preferred embodiment, are long-range nozzles, ensure the treatment of higher areas, thus avoiding temperature stratification and ensuring an efficient mixing of the blown air with the ambient air of the occupied area.

[0035] In addition, the device according to the present invention includes a suction silencer (6), and a blowing silencer (7) which attenuates the noise of the air when it enters the device and moves inside it.

[0036] The device according to the present invention also includes heat exchangers (8), suction temperature sensors and blowing temperature sensors.

[0037] In addition, the air conditioning device also includes a filter (9) common to the first and second modules (1, 2) and fans (10).

[0038] Figures 2 to 4 show the three operating modes of the air conditioning device according to the present invention, determined by a controller.

[0039] In particular, [Fig.2] shows the operation of the device when the air exits only through the first outlets (4), i.e. in displacement diffusion mode; [Fig.3] illustrates the operation of the device when the air exits only through the second outlets (5), i.e. in mixing diffusion mode, and [Fig.4] illustrates the operation of the device when the air exits through the first and second outlets (4, 5) at the same time, i.e. in combined mode.

[0040] During operation, air is drawn in through the filter (9) located on the upper part of the device. The air passes through the intake silencers (6), which attenuate the noise transmitted by the intake, the fans (10), the blowing silencers (7) and the heat exchangers (8), distributing the air to the first outlets (4), the second outlets (5), or both.

[0041] It should be noted that enclosures enclose the equipment and connect the air outlets of the indoor modules to the air outlets, thus creating two separate plenums or compartments. The plenum or compartment corresponding to displacement diffusion is located in the lower part of one of the enclosures, and the plenum or compartment corresponding to nozzle diffusion corresponds to the lower part of the other enclosure and the upper part of both enclosures.

[0042] The two air conditioning modules (1, 2) are controlled independently. The inlet temperature sensor measures the air temperature, which is compared to a setpoint to regulate the position of the valves and the speed of the fans. The outlet temperature sensor is used to control the outlet temperature. Once the setpoint temperature is reached, a controller closes a water inlet valve.

[0043] In addition, for maintenance tasks, the filtration area may include a pressure switch which sends an alarm signal in case of a clogged filter.

[0044] Although the invention refers to a specific embodiment, it is obvious to those skilled in the art that the described air conditioning device is susceptible to many variations and modifications, and that all the aforementioned details can be replaced by other technically equivalent elements, without departing from the scope of protection defined by the attached claims.
