Description

  The present invention relates to a blowout unit connected to an indoor unit of an air conditioner disposed on a ceiling portion of a building via a blowout duct, and an air conditioning system including the blowout unit.

In recent years, grid system ceilings have been introduced in office buildings and the like. The grid system ceiling is a grid of holding bars (T-bars) suspended from the ceiling via a suspension, and each panel divided into a grid by the holding bars has a ceiling panel and air. Arranged air outlets, lighting, etc. for conditioned air (air-conditioned air). In the grid system ceiling, the air-conditioning air outlets, lighting, and the like can be relatively freely arranged according to the arrangement position of the personal space in the office, so that the degree of freedom of partitioning is high.
In an office building where such a grid system ceiling is introduced, a built-in type air conditioner that can relatively freely position the outlet of the conditioned air by an outlet duct is often installed. The indoor unit of the built-in type air conditioner is connected to a blow-out unit including a blow-out chamber connected to the blow-out duct and a blow-out panel arranged corresponding to the blow-out chamber. A wind direction plate (guide vane) for guiding the wind direction in a predetermined direction is provided at the air outlet formed in the blowout panel. Among such blowout units, there are those in which a plurality of wind direction plates formed in an expanded shape are provided at the blowout port, and a shield plate that shields a part of the blowout port is provided at the blowout port (for example, , See Patent Document 1). By selectively shielding a part of the air outlet with the shielding plate, the direction of the air blown out from the air outlet unit into the room is set according to the arrangement position of the air outlet unit.

By the way, a plurality of personal spaces are usually provided in the office below one blowout panel. However, since the temperature and air volume that people feel comfortable are different depending on the person, it is difficult for everyone to make comfortable air conditioning settings. For this reason, in recent years, in order to improve the comfort of air conditioning for each personal space in the office, it is desired to adjust the wind direction according to each person's preference for each personal space.
However, in the blow-out unit (Patent Document 1) of the conventional built-in type air conditioner, air can be evenly blown in four directions by the wind direction plate, but the inclination angle of the wind direction plate is fixed. The wind direction could not be changed, and the wind direction could not be adjusted for each personal space. Moreover, in the said conventional blowing unit, a part of blower outlet is selectively shielded with a shielding board, and it can prevent that conditioned air is blown off from a predetermined | prescribed direction. However, by selectively shielding a part of the outlet with the shielding plate, the air volume from other parts increases, or the blowing efficiency decreases due to the turbulence of the air flow generated in the outlet duct. There was a risk of affecting the comfort of the personal space. Moreover, since the position which shields a blower outlet with a shielding board is fixed at the time of blowing unit installation, it was difficult to change the position which shields a blower outlet with a shielding board after blowing unit installation.
The subject of this invention is providing the blowing unit and air conditioning system which can adjust a wind direction for every direction, when air-conditioning air is blown off in several directions from one blowing unit.

In order to solve the above-mentioned problems, the blowout unit of the present invention is connected to an indoor unit of an air conditioner arranged on the ceiling of a building through a blowout duct and is supplied with the conditioned air through the blowout duct.

Furthermore, since the conditioned air in the blowout chamber is diverted for each blowout opening by the diverter, the blowout unit of the present invention prevents the turbulence of the airflow in the blowout chamber and prevents the airflow direction plate at one blowout opening. When the direction is changed, it is possible to prevent the air blowing efficiency of the conditioned air blown out from the other blowout openings from being lowered. In addition, since each blowing opening is provided with a wind direction plate that can change the wind direction independently for each blowing opening, the blowing unit of the present invention is adapted to wind direction plates when turbulence of the air flow occurs. By adjusting the direction of the conditioned air, the conditioned air can be smoothly blown.

The said structure WHEREIN: It is preferable that the said wind direction board can shield the said blowing opening.
According to the above configuration, since the wind direction plate can also block the blowout opening, when there is a place where conditioned air is not required, the blowout unit of the present invention shields one blowout opening toward that place. By doing so, it is possible not to supply the conditioned air to the place, and it is possible to shield the blowout opening individually for each personal space. Furthermore, since the conditioned air in the blow-out chamber is diverted for each blow-off opening by the diverter, the blow-out unit of the present invention prevents the turbulence of the air flow in the blow-off chamber, and the blow-out opening is provided at one blow-off opening. Even in the case of being shielded, it is possible to prevent the air blowing efficiency of the conditioned air blown out from the other blowout openings from being lowered.

Moreover, each partition part 32a-32d is comprised so that upper part may become low gradually along the shape of the blowing chamber 30, and it becomes the same height as the side surface of the blowing chamber 30 in the side surface of each partition part 32a-32d, Side surfaces of the partition portions 32 a to 32 d are respectively fixed to side surfaces of the blowing chamber 30. Thereby, since the blowing unit 3 can divide the conditioned air smoothly, it can divide the conditioned air for each of the blowing openings 42 while preventing the turbulence of the air flow of the conditioned air by the diverter 32. The conditioned air can be blown out from each blow-out opening 42 substantially evenly.

The horizontal guide vanes 43a of the respective blow-off openings 42 are provided with rotating shafts (not shown) at both ends in the longitudinal direction of the horizontal guide vanes 43a. 41 is supported. Adjacent rotating shafts are connected via a connecting shaft (not shown) as a link mechanism. Further, a lateral guide blade motor 44a is connected to one of the connecting shafts, and the lateral guide blade motor 44a is embedded inside the boundary portion 40a or 40c of the blowing panel 40. Thus, when the lateral guide blade motor 44a is driven, rotation is transmitted to the connecting shaft, and further, rotation is transmitted from the connecting shaft to the rotating shaft, so that all nine lateral guide blades 43a are synchronized. It is configured to rotate.
With this configuration, the lateral guide vane 43a can adjust the angular position (posture) in the lateral direction (arrow X in FIG. 4) to an arbitrary angle, so that the blowout opening 42 can be opened and closed. The blowing direction can be adjusted. Further, since the lateral guide blade motor 44a is connected to the above-described electrical equipment box 16 by a wiring (not shown), for example, the lateral guide blade 43a of the blowout opening 42a is guided longitudinally based on a control signal from the electrical equipment box 16. The blades 43b and the other blowing openings 42b, 42c, and 42d can be rotated independently of the operation of the lateral guide blades 43a, and the horizontal wind direction of the blowing openings 42a can be individually adjusted.

One of the connecting shafts is connected to a vertical guide vane motor 44b, and the vertical guide vane motor 44b is embedded inside the boundary portion 40a or 40c of the blowing panel 40. Thus, when the vertical guide vane motor 44b is driven, rotation is transmitted to the connecting shaft, and further, rotation is transmitted from the connecting shaft to the rotating shaft, so that all nine vertical guide vanes 43b are synchronized. It is configured to rotate.
With this configuration, the vertical guide vane 43b can adjust the vertical angular position (posture) perpendicular to the horizontal direction to an arbitrary angle, so that the blowout opening 42 can be opened and closed, and the vertical blowout direction when opened. Can be adjusted. Further, since the vertical guide blade motor 44b is connected to the above-described electrical equipment box 16 by a wiring (not shown), for example, the vertical guide blade 43b of the blowing opening 42a is guided laterally based on a control signal from the electrical equipment box 16. The blades 43a and the other blowing openings 42b, 42c, and 42d can be rotated independently of the operation of the vertical guide blades 43b, and the vertical wind direction of the blowing openings 42a can be individually adjusted.

For example, since the lateral guide vanes 43a of the blowout opening 42a have a predetermined angle θ in the lateral direction, the conditioned air diverted in the blowout chamber 30 as shown by arrows in FIG. Is blown out. Further, since the vertical guide vanes 43b of the blowout opening 42a have a predetermined angle in the vertical direction, the conditioned air diverted in the blowout chamber 30 is blown into the room at a predetermined angle in the vertical direction from the blowout opening 42a. The
In addition, since both the horizontal guide blade 43a and the vertical guide blade 43b of the outlet opening 42d have an angle of zero and shield the outlet opening 42, the conditioned air is not supplied indoors.
As described above, since the conditioned air in the blowout chamber 30 is diverted for each blowout opening 42 by the diverter 32, the blowout unit 3 can be used when the attitude of the wind direction plate 43 is changed in one blowout opening 42 or Even when the blowout opening 42 is shielded by one blowout opening 42, the air flow in the blowout chamber 30 is prevented from being disturbed, and the blowing efficiency of the conditioned air blown out from the other blowout openings 42 is prevented from being lowered. can do.

Based on the infrared signal, a control signal is transmitted to the lateral guide blade motor 44a of the outlet opening 42a, and the lateral guide blade motor 44a is driven to rotate the lateral guide blade 43a of the outlet opening 42a. Since the one lamp 46 adjacent to the blowout opening 42a is lit while the horizontal guide vane 43a of the blowout opening 42a is rotating, the user desires the user to adjust the wind direction. It can be confirmed by lighting of the lamp 46 whether or not the lateral guide vane 43a of the blowout opening 42a is rotating.
