Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention aims at not only the ventilation of the room and the introduction of fresh outside air but also the humidification function by one unit at high speed, reliably and economically. The present invention relates to a ceiling-mounted ventilation unit for air-conditioning, which always seeks to obtain an optimum environmental condition.

2. Description of the Related Art Conventionally, in this type of structure of a ventilation unit, the indoor intake portion and the outside air introduction portion are respectively constituted by different structures, and provisionally, they are constituted by the same structure. Even if a large number of mechanical devices with completely different functions such as suction and discharge are accommodated in a small aircraft, there is a concern that the overall shape will be bulky in terms of functionality, and in particular, noise from noise generated inside the aircraft will be accompanied by the air supply. It was said that it was extremely difficult to obtain a quiet indoor environment by flowing out into the room.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to fundamentally solve the above-mentioned drawbacks, and it is possible to perform indoor air intake and exhaust operations at the same time with a single device, and, of course, it is particularly desirable. Its main purpose is to take in fresh air into the room and at the same time supply appropriate humidified air. In other words, due to the push-type arrangement of the exhaust blower, the distance between the air blower and the air blower is increased, and during that time, noise in the air flow is naturally dissipated and absorbed, and a better noise reduction effect is expected. In addition to being obtained, it is possible to obtain a reliable and effective action in the humidification function. Further, by biasing the blower part to one side, the indoor area of one of the air supply chamber and the exhaust chamber is expanded, and the expanded space portion is used to make a mechanism such as a heat exchange coil, a humidifier, and each control device. The device can be housed compactly and effectively, and therefore the overall shape can be made extremely small and maintenance work inside the machine can be easily performed from the side surface side of the machine body.

[0004]

As a means for achieving the above object, a ceiling-mounted ventilation unit according to the present invention is provided with a total heat exchanger 2 in the center of the inside of an airframe 1 as shown in the outline of the illustrated example. The outside air introduction chamber 3 and the exhaust chamber 4 are provided in front of the total heat exchanger.
In addition, a return air chamber 5 and an air supply chamber 6 are respectively formed in the rear part, and an external air intake 7 and an exhaust port 9 that open the respective air passages of the external air introduction chamber 3 and the exhaust chamber 4 to the front part of the machine body, Return room 5, air supply room 6
Air return passage 8 and air outlet 1 for opening the ventilation passage of
0 is connected and communicated with each of the outlets, and the blower 11 for the return air is pushed into the outside air introduction chamber 3 and the blower for the exhaust blower 12 is pushed into the return air chamber 5 with the total heat exchanger 2 as the axis. And the heat exchange coil 13 for heating and cooling, the humidifier 14, the drain pan, the control device 15, and other necessary mechanical devices in the air supply chamber 6 and the exhaust chamber 4 respectively. It is characterized by the arrangement. Further, since the outside air introduction chamber 3 and the return air chamber 5 are formed so as to be biased to one side of the airframe, the space inside the exhaust chamber 4 and the air supply chamber 6 on the other side is naturally expanded, Utilizing the space, the heat exchange coil 13, the humidifier 14, the control device 15, and other deionizers,
It is possible to easily arrange each mechanical device required such as a steam generator. Further, according to the present invention, the above-mentioned push-type ventilation blower 11 and exhaust blower 12 are biased to one side, and the filters 17 and 18 are detachably fitted to the rear parts of the respective blowers, whereby Therefore, it is possible to reliably remove dust from the inside of the machine, and at the same time, it is possible to perform operations such as maintenance work inside the machine from the side surface of the machine body significantly easily and easily. Further, by forming the by-pass passages 16 for outside air and exhaust in the upper part of the machine body 1 and the upper part of each of the intake and exhaust chambers formed in the machine, in parallel and integrally,
It goes without saying that the outside air can be cooled in the intermediate period. By the way, the present invention has very good compatibility and very good stability by installing the total heat exchanger in the center of the cabin, and it can greatly reduce the amount of heat used during heating, especially the push-in type of the blower. The purpose of the present invention is to provide an economical air-conditioning ceiling-mounted ventilation unit that has better and more effective silencing and humidifying functions depending on the layout.

[0005]

The above ventilation unit is used by suspending or embedding it on a predetermined ceiling such as in the middle of indoor or outdoor, and using the air outlet 10 and the return air port 8 on the indoor side, and the outdoor air intake 7 and the exhaust port. The polluted air in the room can be removed by operating the intake and exhaust ports of 9 directly or by duct connection to communicate with the inside and outside of the room, returning when necessary such as intake and ventilation, and operating the exhaust blowers 11 and 12. Although it flows from the return air port 8 to the total heat exchanger 2 through the return air chamber 5, a part of the heat quantity in the flowing air is absorbed by the action of the total heat exchanger 2 and unnecessary parts are exhausted. The gas is discharged to the outside through the exhaust port 9 via 4 On the other hand, at the same time as the release of the polluted air, fresh outside air sucked into the machine from the outside air intake 7 passes through the outside air introduction chamber 3 and the total heat exchanger 2
In the meantime, while being heated by the amount of heat to be absorbed, it flows into the air supply chamber 6 and is heated to an appropriate temperature by the heat exchange coil 13 and is supplied into the room together with humidified air from the outlet 10. Although not shown in the illustrated example, the air flow is mixed with fresh outside air, the entire amount of return air from the room, or a part of the exhaust gas by the switching operation of the damper installed in the machine, and the heat is reheated. It is possible that heat is exchanged at an appropriate temperature in the exchange coil 13 and ideal cold and warm air can be sent to the room.
