BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning panel in which a heat source device for producing cold air is attached to a partition to enable a refrigerant-air type personal air conditioning, and the inside of the panel is particularly effective as a passage for the conditioned air. By using it, the exhaust heat from the OA equipment can be absorbed without being dissipated.

[0002]

2. Description of the Related Art Recently, some offices using OA equipment have come to use an air conditioning panel in which a panel also serving as a partition and a heat source equipment are combined in order to adopt personal air conditioning. As shown in FIG. 2, in this type of air conditioning panel, a heat source device cover 23 accommodating the heat source device 22 is assembled to the panel 21, and the heat source device cover 23 is provided with an intake port 24 and a drain tank outlet 25.

Then, the room air is sucked through the air inlet 24 of the heat source device cover, a part of the air is passed through the condenser coil to dissipate the heat, and the heat is exhausted through the exhaust duct in the panel 21 through the exhaust port 26 in the upper part of the panel. . Further, other sucked air is passed through the evaporator coil to be a cold air, and is blown out from the cold air outlet 27 in the upper part of the panel through the cold air duct in the panel. The cold air blown out in this manner cools around the desk of the OA device, mixes with the exhaust of the heat source air, and returns to the intake port 24 of the heat source device cover again.

[0004]

In the conventional air-conditioning panel, the exhaust passage for the heat source air in the panel is composed of an insulated duct, but the remaining space is a cold air chamber for personal air conditioning. The heat loss was large due to the large. Further, since the exhaust heat of the OA equipment is once dissipated into the room and then enters the intake port of the heat source equipment cover, a large amount of cool air in the room is required, and the desk area becomes a load for the heat source equipment, resulting in a large energy loss. . Furthermore, there is a problem that driving noises of the compressor and the fan of the heat source device leak from the suction port of the heat source device cover, which causes annoyance. Therefore, the present invention collects the exhaust heat from the office automation equipment without dissipating it around the desk, reduces the load on the heat source equipment, and further reduces the heat loss of the cold air for air conditioning in the panel, and further from the heat source equipment. The purpose is to be able to block the sound of.

[0005]

According to the present invention, a part of sucked air is exhausted by a condenser coil in a heat source device and exhausted from an exhaust port of a panel, and another sucked air is cooled by an evaporator coil. The above object is achieved in an air-conditioning panel configured to be blown out from the air outlet of the panel. Therefore, an intake port is provided at a portion of the panel facing the vicinity of the exhaust heat of the OA device, a cold air blowout passage and an exhaust passage from the heat source device are provided in the panel, and an intake port of the panel and an intake port of the heat source device are provided. A passage was established to communicate with.

[0006]

In the above air-conditioning panel, the exhaust heat of the OA equipment is not dissipated and enters the inlet of the heat source equipment through the intake passage of the panel through the intake passage. Therefore, the cooling load for personal air conditioning can be a load to bring the temperature to an individual's preference, and the amount of cool air in the room can be small. Part of the sucked air is exhausted from the condenser coil and discharged from the exhaust port through the exhaust passage of the panel, and the other part is cooled by the evaporator coil and is blown out through the outlet passage of the panel. Blow out from. In this case, the blowout passage of the cool air is formed in the space excluding the exhaust passage and the intake passage in the panel, and the heat loss of the cool air can be reduced. Furthermore, since the cover of the heat source device is not provided with an intake port for sucking indoor air, the drive sound of the compressor or fan of the heat source device is unlikely to leak to the outside.

Embodiment An embodiment of the present invention will be described with reference to FIG. In the air conditioning panel of the present invention, a heat source device cover 3 accommodating a heat source device 2 is assembled to a panel 1 having a hollow inside.
The heat source device 2 has a condenser coil 2a and an evaporator coil 2b, and a part of the air sucked from the suction port 2c is exhausted from the condenser coil 2a and exhausted from the exhaust port 2d, while The intake air can be cooled by the evaporator coil 2b and discharged from the air outlet 2e.

The panel 1 is provided with an intake port 4 at a portion of the panel facing the vicinity of the exhaust heat of the office automation equipment. Further, an outlet 5 for cool air is provided on the upper front surface of the panel 1, and an exhaust port 6 is provided on the side of the upper end of the panel 1. As shown in FIG. 1 (a), the inside of the panel 1 is a partition plate 1b with good heat insulation.
Is divided into three passages 7a, 7b, 7c, and the inner circumference of each passage is configured to have a good heat insulating property.

The intake port 4 of the panel is communicated from the passage 7a to the suction port 2c of the heat source device through the through hole 3a of the heat source device cover 3 and the pipe line 8, and the exhaust heat of the OA device is OA.
The heat is not emitted from the exhaust heat chamber 9 of the equipment, but enters the intake port 4 of the panel together with the room air and is sent to the heat source equipment 2. The panel outlet 5 has a passage 7b.
From the heat source device 2 through the through hole 3b of the heat source device cover 3
Is communicated with the air outlet 2e, and the cool air is blown from the air outlet 2e to the air outlet 5 side of the panel. The exhaust port 6 of the panel is communicated with the exhaust port 2d of the heat source device 2 from the passage 7c through the through hole 3c of the heat source device cover 3, so that the exhaust gas of the heat source device 2 is exhausted from the exhaust port 6. There is.

[0010]

[Effect of the device] In the air conditioning panel of the present invention,
Since the passages for intake, cold air blowing, and exhaust are provided, the cold air blowing passage has a smaller space than the conventional case without the intake passage, and the heat loss of the cold air can be reduced. In addition, the exhaust heat of OA equipment is not dissipated and is drawn into the heat source equipment side from the intake port provided in the panel, so the cooling load for personal air conditioning is only the load to bring it to the temperature desired by the individual. It requires less cold air. Furthermore, since the heat source device cover is not provided with an intake port, the sound of the compressor and fan of the heat source device is blocked, and it is difficult for it to leak outside. .
