Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor-standing air-conditioning ventilation unit for an air conditioner, which has a vertically elongated shape as a whole and allows not only fresh air to be introduced into a room but also direct cooling by the outside air.

[0002]

2. Description of the Related Art Usually, there are four seasons when air conditioning is not required, that is, from May to July when fresh outside air is required. In addition, most of the air conditioners that have been developed so far are for indoor cooling and heating air conditioners, so it is not possible to directly cool the room with outside air. It is difficult to carry out the introduction. Also, recently, due to the indoor environment, such as hospital rooms, laboratories, elderly rooms, private rooms, etc., problems may arise with indoor maintenance work, and various control equipment, piping parts, etc. may be exposed on the indoor surface. Has a drawback that the design feeling is significantly deteriorated. Moreover, in these air conditioners, since various mechanical devices are laid out in a narrow space in a cluttered manner, the overall height of the air conditioner becomes bulky. It was so-called unsuitable for installation in the room because the noise generated in the aircraft also flowed out together with the air.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned drawbacks of an air conditioner which is installed indoors, and has an overall shape of a small size, and of course not only a narrow place in a room. Its main purpose is to make it possible to install easily using an outdoor space such as a balcony or under the roof, and at the same time to allow direct cooling by outside air.

[0004]

As a means for achieving the above-mentioned object, as shown in the drawings, the present invention has an air supply port 2 in the upper rear portion of a machine body 1 formed in a vertically elongated shape and a return air port 3 in the lower portion. The front of the exhaust port 4 and the outside air intake 5, etc.
An exhaust port is provided for each opening, and a return chamber A, a blower chamber B, and
Each of the outside air introduction chamber C, the exhaust chamber D, and the air supply chamber E is partitioned and formed, and the above chambers are vertically communicated with each other through the air passages 6a and 6b, and the total heat between the outside air introduction chamber C and the exhaust chamber D is further increased. An exchanger 15 is installed and blower passage switching dampers F1 and F2 are arranged between the blower passages 6a and 6b so that the blower passages 6a and 6b can be easily switched. In addition, the air passage 6
In a and 6b, a return blower, an exhaust blower 7, an air blower 8 and cold and hot water heat exchange coils 9 and 10, a drain pan 11,
Mechanical devices such as a humidifier 12, filters 13, 14 and the like are respectively arranged, and vertically long rhombus-shaped total heat exchangers 15 are vertically installed in the air passages 6a, 6b formed by the outside air introduction chamber C and the exhaust chamber D. The composition is also a feature.

[0005]

[Operation] The ventilation unit having the above structure is installed in the corridor,
It is installed in an outdoor space such as a balcony, and the return air port 3 and the air supply port 2 are opened directly or indoors by connecting ducts, and one of the exhaust ports 4 and the outside air intake port 5 is directly outside or a duct. Open the connection by connecting. In such a state, the damper F for switching the air passages A, B when the air blowers 7, 8 for return, exhaust and air supply are in operation
When 1, F2 are fully closed, the polluted air on the indoor side flows from the return air port 3 to the arrow A and is discharged to the outside from the exhaust port 4 through the air passage 6a, while the fresh air outside the outdoor air intake port 5 Further, the air flows in the direction of arrow a, passes through the air supply passage E from the air supply passage 6b, and is sent into the room through the air supply port 2. Further, during that time, since the return air from the room passes through the total heat exchanger 15, a part of the heat amount is recovered. That is, during normal operation, the outside air introduced into the machine is cold in the air supply chamber E and is cooled by the hot water heat exchange coil 9.10, for example, by the cold water heat exchange coil 9 during cooling, and by the hot water heat exchange coil during heating. At 10, the air is heated to an appropriate temperature, and cold and warm air is blown into the room. Further, in the case where the room is dried in the cold and warm air and proper humidification is required, it is possible to simultaneously feed appropriate humidified air by the action of the humidifier 12. Next, by opening the blower passage switching damper F1, the air from the room flows into the blower passage 6b from the bypass passage, so that not all of the return air is discarded, but only part of it is discharged outdoors. It is possible to economically utilize the amount of heat stored in. In particular, in the present invention, when the outside air cooling is required at a time when the heating / cooling is not required due to the indoor environment, the blower passage switching damper F1 is closed and F2 is opened so that the outside air does not pass through the total heat exchanger 15 As shown in (c), the air directly flows into the blower chamber B, and the outside air is blown into the room through the air supply port 2. In the meantime, naturally, the cold and hot water heat exchange coils 9 and 10 are stopped from passing water. However, when more cool air is required, the cold water coil 10 can be passed to cool the cold air and cool it again. If it passes, damper F2,
It can be easily solved by adjusting the opening and closing of F2.
