Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is to be installed on an indoor ceiling or the like and is used, so-called low noise type in which the overall shape is formed to be extremely flat, bulky and small, and noise is extremely reduced. Regarding air conditioners.

[Conventional technology]

Conventionally, this type of air conditioner is provided with an air inlet (2) on one side of the airframe (1) and an air outlet (3) to the room on the other side as shown in the first illustration, and the air inlet (2 ), A blower (4) is provided in the vicinity of the inside, and various mechanisms such as a humidifier (6) and a heat exchange coil (7) are provided in a blower passage (5) in front of the blower.

[Problems to be Solved by the Invention]

Therefore, in the above conventional air conditioner, the heat exchange coil (7) is arranged in the front air passage (5) of the air outlet of the air blower (4) so as to be orthogonal to the air blowing direction. The blown air directly collides against the coil surface, which not only makes the air resistance extremely large, but is also the cause of the noise that has been a matter of concern.

The present invention is intended to fundamentally solve the cause of such noise generation, and provides an energy-saving low-noise air conditioner capable of significantly reducing air resistance and greatly reducing power consumption. It is intended to be provided.

[Means for Solving the Problems]

As a means for achieving the above-mentioned object, the low noise type air conditioner of the present invention has an air blower disposed inside an airframe provided with an air inlet on one side and an air outlet on the other side, and is suitable on both sides of a blower passage in front of the blower. The heat exchange coils are arranged substantially parallel to each other in parallel or in a slanting manner with a space therebetween, and a flow guide partition plate is installed at the air sending side ends of the heat exchange coils on both sides. Is.

It is also possible to install a flow guide partition plate on both ends of one side of the heat exchange coil on both sides of the air delivery side so as to be openable and closable.

For the same purpose, it is possible to attach the damper mechanism to the above-mentioned flow guide plate.

Further, in the present invention, the mixing chamber C is provided between the flow guide plate (8) and the air outlet (3), and the eliminator / reheater heater (12) is provided inside the outlet (3) in front of the mixing chamber C. It may be possible to form a low noise type air conditioner characterized by being provided with.

[Action]

In the above structure, the airflow from the blower (4) is diverted and diffused in the direction of the arrow by the air guide partition plate (8), and this flows through the heat exchange coils (7) and (7) arranged on both sides and the air outlet ( From 3), it is possible to supply cold / warm air at an appropriate temperature to the room.

Further, if the air guide partition plate (8) is arranged in the air passage (5) so as to be openable and closable, the air blown from the air blower (4) can be passed through the heat exchange coils (7), (7). It is also possible to freely adjust the amount of passage to the heat exchange coil by simply opening one of the bypass passages or adjusting the opening / closing inclination angle.

Furthermore, by disposing the eliminator reheat heater (12) in the vicinity of the air outlet (3), it is possible to prevent water droplets from scattering into the duct.

EXAMPLES Examples of the present invention will be described below with reference to the drawings.

Reference numeral (1) is an airframe, (2) is an indoor air inlet (2), and outside air inlets (2) 'are opened in parallel, and ducts a, a are connected to the respective mouths. (3) is an air outlet that can be opened on the other side of the airframe, (4) is a blower, and (4) 'is an electric motor. A plurality of heat exchange coils (7), () are provided on both sides of the blower passage (5) in front of the blower. 7) are arranged in parallel so as to face each other with an appropriate interval.

Further, the heat exchange coils (7) and (7) may be arranged with a wide width on the wind receiving side and a narrow width on the air blowing side, and may be arranged in a substantially inclined shape in a slightly inclined shape.

According to the present invention, there is provided an air guide partition plate (8) in the center of the front side of the both side heat exchange coils (7), (7) which are arranged in parallel and face each other. The partition plate (8) is a flat plate if necessary, or V as shown in the second drawing.
Any shape such as a mold or a curved mold is used. Further, an eliminator and reheat heater (12) is provided in the mixing chamber C inside the air outlet (3).

By the way, the air flow from the blower (4) is the air guide partition (8).
Depending on the arrow, the heat exchange coils (7), (7) on both sides
A predetermined amount of cold / warm air can be supplied to the room by removing the humidity from the air outlet (3) through the eliminator and reheat heater (12).

Further, according to the present invention, the air guide partition plate (8) can be opened / closed on both sides or one side as shown in FIG. 4, and the same air flow as above can be obtained when closed, but the blower (4 The air flow from () does not pass through the heat exchange coils (7) and (7) and is made direct current to form a bypass path.

Further, by opening the air guide partition plate (8) 'inward as shown by the arrow, the amount of air passing through the heat exchange coil (7) can be suppressed and adjusted to reduce the coil capacity by half. That is, depending on the opening / closing inclination angle, it is possible to change and request arbitrary air conditions at high speed.

As another embodiment of the present invention, as shown in FIG. 5, a damper mechanism (13) is provided on the air guide partition plate (8) to form a bypass passage or a partial air bypass passage. At, the heat exchange coils (7) and the cold / warm air from (7) are mixed.

Reference numeral in the drawing, (9) is a drain pan, (10) is a filter, and (11) and (11) are water inlets and outlets of the coil.

In addition, the above embodiment is a description of a ceiling-mounted air conditioner, but it goes without saying that it is possible to use the structure as a whole as a low-noise air conditioner of other types such as a floor-standing type. Absent.

〔The invention's effect〕

Since the present invention is based on the above configuration, it has various effects described below.

Due to the air guide plate (8), the air blown from the blower (4) does not directly contact the heat exchange coils (7) and (7) but flows to the coils on both sides in a distributed manner, so that the coil abutment is used. The generation of wind noise is blocked in advance, resulting in extremely low noise.

Further, the air guide partition plates (8) and (8) 'are formed so as to be openable and closable on both sides as required, or a damper mechanism (13) is attached to a part of the air guide partition plates (8) to form an open circuit. It becomes a bypass passage in the body, and a mixed air flow of the bypass air flow and the heat exchange air flow can be easily obtained in a part of the open path. Furthermore, depending on the opening / closing adjustment of these, the heat exchange coil (7) One lung operation is possible at the time of failure and when not in use, power consumption can be greatly saved, and the amount of wind passage can be arbitrarily controlled and adjusted, which has the economic effect of adapting to any air condition during the intermediate period at high speed. is doing.

Furthermore, since the heat exchange coils (7) and (7) are distributed and arranged on both sides in the air passage (5) in comparison with the conventional bulky and heavy unit structure, a metering coil with a relatively small capacity is used. This makes it possible to form the whole shape into a very low bulk, small size, and meter.

In particular, by arranging the eliminator and reheat heater (12) in the vicinity of the inside of the air outlet (3), it also has the effect of completely solving the water droplet scattering at the air outlet, which was a drawback of the conventional machine. is doing.
