Description

The invention relates to an air conditioning unit for installation near the ceiling according to claim 1. Modern room concepts are characterized by open ceilings, allowing the technical equipment, which would otherwise be concealed within the ceiling cavity, to remain visible. These concepts forgo other ceiling systems. Such concepts are used, for example, in rooms with ceiling heights of 3 to 5 meters, such as offices, government building entrances, supermarkets, and hotels. Often, elements for lighting, acoustic damping, or air conditioning are suspended from exposed concrete ceilings. These concepts utilize round light fixtures, particularly ring lights, acoustic panels, or air outlets. Common air conditioning units are designed as ceiling cassettes, which lack the necessary compactness for the described application and do not integrate aesthetically well into the room design. Due to the requirements for air conditioning units, these are designed to be bulky, in order to provide space within a single housing for fans, heat exchangers, pumps, electrical components, and the like. Therefore, above the unit itself, which in known designs is exclusively visible, there are additional components. additional equipment components that remain visible with open ceilings and disrupt the room concept. Based on this, the object of the present invention is to create an air conditioning unit for installation near the ceiling, which is particularly compact and suitable for installation near the ceiling. An air conditioning unit for solving this problem has the features of claim 1. Accordingly, the air conditioning unit has a body that can be mounted with its upper surface particularly close to the ceiling of the room to be air-conditioned. A lower area of the body, in particular a downward-facing underside, is closed. Another essential feature of the invention is that a circumferential wall of the body has at least one air outlet for discharging air. This compact design of the air conditioning unit according to the invention makes it possible to mount it particularly close to the ceiling of a room. Any technical components that would otherwise be located on the body are integrated into the body. Preferably, the invention further provides that the wall surrounding the device body has at least one air outlet for discharging air in an upper half, particularly in an upper third or an upper quarter. In particular, it is conceivable that the surrounding wall has two, three, four, five, or more air outlets, these air outlets being arranged in a ring around the device body. Preferably, the invention provides that the surrounding wall has six to eight air outlets arranged in a ring around the surrounding wall. The ring-like positioning of the air outlets around the device body, which is particularly cylindrical, allows for the creation of a particularly homogeneous near field, as well as a far field, of airflow, thereby generating a particularly pleasant climate in the room. By using multiple air outlets, the outgoing air receives a sufficiently large momentum to achieve a sufficient horizontal throw distance into the room. Simulations have shown that the use of six to eight air outlets, in particular, contributes to a homogeneous far field. Another advantageous embodiment of the invention may provide that the air outlets are formed by adjacent wedges, wherein the wedges are arranged in a star-like pattern in the The air conditioning unit is arranged in a wedge configuration. Within the unit's body, several wedges are positioned along an outer edge, with their longer side facing outwards and their shorter side facing inwards. The number of wedges determines the number of air outlets. Using six wedges, spaced at equal angular intervals around the edge of the unit, creates six air outlets. The wedges' shape initially generates six separate but diverging air jets in the immediate vicinity of the air conditioning unit. This means that no air flows between two adjacent air jets in the immediate vicinity. Furthermore, the wedges are designed so that the air jets merge again in the far field of the air conditioning unit, i.e., after a few meters, creating a homogeneous air curtain. A particularly advantageous embodiment of the invention may provide that the wedges are designed differently, in particular having different lengths and/or opening angles, in order to generate a homogeneous airflow pattern. Due to the positioning of the technical components within the device body, especially due to the eccentric positioning of a fan, the wedges have different shapes. Since the air within the device body is supplied to the wedges at different velocities and pressures due to the positioning of the technical components, the shape of the wedges is adapted to their respective relative positions to the technical components such that the exiting air jets are at least nearly identical. Thus, a symmetrical near field can be generated by the position
