Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ceiling-mounted air conditioner.

BACKGROUND TECHNOLOGY Conventionally, an air conditioner, such as a fan coil unit, which is embedded in the ceiling for equipment such as a building, has the following characteristics, as shown in FIGS. 6 and 7.
It consists of a main body 1 suspended so as to face an opening in the ceiling surface, and a decorative panel 2 that faces the bottom surface of this main body 1 and is exposed under the ceiling. It is divided by
It includes a blower 4 fixed to the partition plate 3 and a heat exchanger 5 through which a medium such as cold or hot water passes. The decorative panel 2 also has a suction port 6 formed on one side in the longitudinal direction and communicating with the blower 4, and a blowout port 7 communicating with the blowing direction of the heat exchanger 5 and facing the suction port 6. It is provided.

Then, by operating the blower 4, indoor air under the ceiling is sucked in through the suction port 6 on one side of the decorative panel 2, passes through the heat exchanger 5 through the discharge port of the blower 4, and is blown into the room from the blowout port 7. I was starting to let it out.

Problems to be Solved by the Invention In such a conventional configuration, since the inlet 6 is long in the longitudinal direction and the outlet 7 is oriented in one direction in the longitudinal direction. In large rooms such as the Due to the opening 6 and the outlet 7 in the same direction, the air is circulated in one direction, and the blowing direction tends to be biased, resulting in poor temperature distribution within the large room, making it impossible to obtain a better temperature distribution. The point was hot.

The present invention solves these problems,
The purpose is to obtain a good temperature distribution even in the central part of a large room.

Means for Solving the Problem In order to solve this problem, the present invention provides a blower that is partitioned into the main body by a partition plate and communicated with the suction flow path;
A heat exchanger that faces the blower and communicates with the blowout flow path, a makeup that is mounted so as to be exposed on the ceiling surface below the main body, and has a suction port that opens in the longitudinal direction, and a blowout port that also opens in the longitudinal direction. A chamber unit is provided between the lower inside of the main body and the decorative panel to form the suction flow path and the blowout flow path, and the chamber unit includes a partition wall that partitions a central portion. , a suction flow path and a direct blow-off flow path are provided on one side divided by the partition wall, and a detour blow-off flow path is provided on the other side, and a direct blow-off flow path having the same cross-sectional shape as the direct blow-off flow path is provided directly below the direct blow-off flow path. The outlet and a detour outlet having the same cross-sectional shape as the detour outlet are formed at relative angular positions on the opposite side of the detour of the detour outlet.

Effect With this configuration, the indoor air sucked in from the inlet of the decorative panel flows through the suction channel of the chamber unit to the blower, and from this blower it passes through the heat exchanger and becomes cold or warm air. Air is divided into a bypass blowout passage and a direct blowout passage of the chamber unit, and is blown into the room from positions at relative angles.

However, the direct air outlet flow path and the detour air flow path are separated by a partition wall, and in the detour air flow path, air flows through the same cross-sectional shape, so there is no sudden expansion or contraction, and there is no resistance. Therefore, the airflow speed can be maintained without reducing the wind speed, and since each air outlet is diagonally arranged, the temperature distribution becomes more reliable.

Embodiment An embodiment of the present invention will be described below based on FIGS. 1 to 5. The main body 12 of the air conditioner is hung and installed so that the lower part faces the opening 11 of the ceiling surface 10. The inside of this main body 12 is
It is divided into two rooms by a partition plate 13, and one room has a partition plate 1.
A blower 14 fixed to the air blower 14 is disposed in another room, and a heat exchanger 15 and a drain pan 16 that face the discharge port 14a of the blower 14 through which hot and cold water flows are provided. The main body 12 is located in the opening 11 of the ceiling surface 10.
A decorative panel 17 is provided, which is attached to the partition frame 2.
It consists of air outlets 22, 22a formed by a partition plate 21 with 0 space apart, and the air outlets 22, 2
2a are provided at relative angles to each other as shown in FIG. The opening 23 adjacent to the air outlet 22 has a configuration in which no air flows through it, the opening 23a adjacent to the air outlet 22a communicates with the suction passage 27, and the central portion is provided for inspection, etc. An opening/closing panel 24 that can be opened and closed is provided. Below the main body 12, there is provided a chamber unit 25 which is attached closely to the inner periphery of the main body 12, and this chamber unit 25 is formed in an L shape as a whole, and has a partition wall 26 in the center. Arrow A
As shown in FIG. 2, the suction flow path 27 penetrates from the bottom to the top to form a half suction channel 27 on one side in the longitudinal direction, and the air flow on one side is such that the air that has passed through about half of the heat exchanger 15 is directed in the direction of arrow B. As shown, it becomes a direct blow-off channel 28 that blows out in the downward vertical direction, and the direct blow-off channel 2
A direct outlet 30 having the same cross-sectional shape as the direct outlet flow path 28 is provided directly below the outlet 8 . In the other flow path, the air that has passed through about half of the heat exchanger 15 becomes an L-shaped detour blowout flow path 29 partitioned by a partition wall 26 as shown by arrow C, and on the opposite side to the inlet side,
A detour outlet 31 having the same cross-sectional shape as the detour outlet flow path 29
is provided and formed.

In the above configuration, when the air conditioner is operated, indoor air flows in through the suction ports 19 and 23a provided on both sides of the opening/closing panel 24, is concentrated in the suction channel 27 of the chamber unit 25, and passes through the air blower. 14, the cold and hot air that has passed through the heat exchanger 15 flows downward. At this time, heat exchanger 1
The air that has flowed through approximately half of the side of the decorative panel 17 flows vertically downward through the direct blow-off channel 28, exits from the direct blow-off port 31, and is blown into the room from the blow-off port 22 of the decorative panel 17. On the other hand, the air that has flowed through the remaining half of the heat exchanger 15 flows through the detour outlet 29 in an L-shape, exits the detour outlet 29 provided on the opposite side, and flows further downward. Air outlet 22 of panel 17
It is blown into the room from a. At this time, the direct blowout flow path 28 and the detour blowout flow path 29 are separated by the partition wall 26, and are each dedicated flow paths. Flows, there is no sudden expansion or contraction, and there is little resistance. Therefore, the blowing air speed can be maintained without decreasing the wind speed, and a good temperature distribution can be obtained.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention provides a system in which air that has passed through about half of the heat exchanger below the main body flows through a direct blow-off channel and is communicated with one blow-off port of the decorative panel. At the same time, the air that has passed through the remaining half of the heat exchanger is separated from the partition wall, flows through the L-shaped detour air flow path, and is delivered to the diagonal position of the decorative panel without rapidly expanding or contracting. Since the air outlet is connected to the other outlet, there is less resistance in the air path, and the air velocity does not decrease, and the air is blown out over a wide area indoors, making it suitable for use in central ceilings of large rooms such as buildings. When installed on a surface, the temperature range is wide and the temperature distribution is good.
