Considering that this location is also indicated for perfect sound propagation, the equipment subject to the present application couples, on the side cover (side of the housing) of the evaporator, with bold and innovative functionality, speakers with Bluetooth connection, thus facilitating the connection with smart devices or simply to listen to music in an air-conditioned environment without the need to carry the speaker from one place to another inside a house.BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 illustrates the evaporator unit of the device according to the present application, in which the air flow direction fins, the air outlet opening, the air conditioning unit remote control signal receiver, the air inlet opening and speakers with Bluetooth connection are highlighted.DETAILED DESCRIPTION

[0013] The air conditioning unit according to the present application consists of a split-type air conditioner comprising an evaporator unit, a condenser unit, a compressor unit, an expansion valve, a valve and pipes interconnecting the units; the evaporator unit comprising a first housing, a first heat exchanger and a first ventilation assembly; the condenser unit comprising a second housing, a second heat exchanger and a second ventilation assembly; the compressor unit comprising a compressor; wherein the evaporator unit and the condenser unit are physically separated from each other, as in any conventional split-type air conditioning unit. According to the present invention, however, the evaporator unit couples, on the side of its side cover / housing, speakers with Bluetooth connection. The sides were chosen seeking a more harmonic propagation of the music that one wishes to listen to, without interference from the air current propagated by the air conditioning fins. This configuration is not disclosed or suggested in any of the prior art documents.

[0014] More specifically, the evaporator unit of the device according to the present application, presents, in its housing (1), in addition to the air flow direction fins (2), the air outlet opening (3), the remote control signal receiver (5) of the air conditioning unit and the air inlet opening (4), speakers (6) with Bluetooth connection.

[0015] In a preferred embodiment, two speakers (6) are located on the same lateral side of the housing (1).

[0016] In a second embodiment, each of the two speakers (6', 6") are located on both sides of the housing (1).

[0017] The split -type air conditioning unit according to the present invention is preferably installed centrally in the room, for perfect distribution of the cooled air. Considering that this location is also suitable for perfect sound propagation, the equipment subject to the present application couples speakers with wireless connection, thus facilitating the connection with smart devices or simply to listen to music in an air-conditioned room without the need to carry the speaker from one place to another inside the house.

[0018] The coupling of the speaker to the cabinet of the evaporator unit of the split -type air conditioning unit is quite simple, especially considering that these are not wired speakers, the speaker being a box that comprises an electrical circuit, acoustic module and speaker, the electrical circuit being responsible for filtering the audio signals received by the box, enabling the reproduction of the sound by the speaker, the only restriction being the need for the speaker (6) to have dimensions compatible with the cabinet of a conventional Split -type air conditioning unit.

[0019] Wireless communication devices typically operate in radio frequency (RF) bands. Wide area network (WAN) providers typically purchase licenses to operate wireless communication systems in one or more of a plurality of RF bands. These systems employ methods that allow multiple access by mobile stations to a common band of frequency channels.

[0020] These systems generally operate in licensed RF bands. Other systems operate in unlicensed RF bands. Systems operating in licensed RF bands have control over transmissions on licensed frequencies and channels. This allows the operator to ensure the reliability of the data, and in particular, the control information used to control channels and maintain and establish connections. Systems operating in the unlicensed RF band do not have this control and data transmission errors may occur as a result of uncoordinated transmission by different users and service providers.

[0021] One WAN access technique is frequency division multiple access (FDMA), which enables multiple access by assigning mobile stations to different frequency channels within the RF band. Some of these systems employ frequency hopping, where data is transmitted to and from the intended mobile station while periodically changing frequency channels. Periodic channel hopping occurs at a regular time interval, for example, one frame. Coordinated frequency hopping systems use predetermined hopping patterns, or hopping sets, where the hopping sets are coordinated among all mobile stations to ensure that signals to and from two or more mobile stations do not occur simultaneously on the same frequency channel. Uncoordinated frequency hopping does not coordinate the hopping set between mobile stations, resulting in a periodic occurrence of simultaneous signal transmission on the same frequency. Such simultaneous transmissions are referred to as channel collisions. Data reception errors occurring during a channel collision are referred to as channel collisions. Uncoordinated frequency hopping within this type of system is generally not used since channel collisions and resulting data collisions can occur. It is worth noting that coordinated frequency hopping within the Industrial Scientific and Medical (ISM) bands is prohibited in order to avoid spectrum aggregation by a single type of service. Systems such as Bluetooth, for example, operate within the ISM bands. In this way, the Bluetooth connection of the speakers does not suffer interference from the remote control for controlling the air conditioning itself.

[0022] It is also important to highlight that, when the present application is put into practice, modifications may be made in relation to certain details of construction and shape, without departing from the fundamental principles that are clearly based on the context of the following claim, it being understood that the terminology used is not intended to limit the present model.
