Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor-standing type ventilation unit for air conditioning, in which the entire machine body is vertically thin and compact, and it is possible not only to introduce fresh outside air into the room but also to directly cool the outside air.

[0002]

2. Description of the Related Art Generally, there are four seasons when air conditioning is not required, that is, from May to early July, when fresh outside air is required. In addition, since most of the air conditioners that have been developed so far have a mechanism for cooling and heating the room, it is difficult to perform direct cooling by outside air, and even if outside air is introduced into the room When the structure of the window part is a closed and fixed type such as in a lobby, a private room, a patient room, etc., it is completely impossible to open the window to introduce fresh outside air. Moreover, in these air conditioners, since various mechanical devices are clutteredly arranged in a small machine, the overall machine height becomes bulky and wide, and therefore, there is no restriction in terms of installation effectiveness in the room. Of course, various control devices and pipings attached to the air conditioner are exposed to the inside of the room to remarkably reduce the design feeling of the room, and the noise generated in the room also flows out into the room. It had drawbacks.

[0003]

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned drawbacks of an air conditioner installed in a room, and has a vertically long compact shape as a whole.
Its main purpose is to enable it to be easily installed anywhere in the outdoor space such as corridors and balconies, as well as to prevent the noise from flowing into the room, and at the same time to allow direct cooling by outside air. There is.

[0004]

As a means for achieving the above object, the present invention provides a return air port 3, an exhaust port 4, an outside air intake port 5, and an air supply port inside a vertically elongated machine body 1 as shown in the accompanying drawings. The mouth 2 is communicated with each of the air passages 6a and 6b, and the cooling and hot water heat exchange coils 7 and 8, the humidifier 9, the air blower 11 and the exhaust air blower 12 are provided in the air passages 6a and 6b, respectively. It is characterized in that it is arranged in a vertical column and several total heat exchangers 13, 13 are arranged in a row between the outside air introducing chamber E and the exhaust chamber D. Further, the air passages 6a and 6b to be described above
By arranging the outside air bypass damper 14 between them, the air circulating in the machine is returned, exhausted, and switched to any direction such as total outside air cooling, so that not only indoor cooling and heating air conditioning but also all outside air cooling operation can be performed. We could have achieved it.

Particularly, in the present invention, the air passage 6 is provided.
Several total heat exchangers 13 having a vertically elongated rhombic cross section between a and 6b,
By arranging them in a row in the left-right direction, the overall shape can be made smaller and more compact as will be described later.

Further, by providing the front panel 17 on the front portion of the machine body 1 so as to be openable and closable, maintenance work such as inspection and repair in the machine body can be easily performed from the front side of the machine body.

Further, a blower pipe 19 having a silencer mechanism 18 of an appropriate shape previously arranged in a cylinder is connected to the air supply port 2 and the return air port 3 which are opened at the back of the machine body 1. As a result, it is possible to mitigate and muffle the noise of noise that flows into the room from the inside of the machine, and to demand quiet air conditioning in the room.

[0008]

The ventilation unit having the above-described structure is installed in an outdoor location such as a corridor or a veranda, and the air supply port 2 and the return air port 3 are opened to the indoor side directly or by duct connection, and The exhaust port 4 and the outside air intake port 5 are opened to the outside directly or by duct connection. In such a state, the outside air bypass damper 1 is used when the blowers 11 and 12 for return, exhaust and air supply are in operation.
By making 4 a closed path, the polluted air on the indoor side flows from the air return port 3 of Ay to the return air chamber F, passes through the total heat exchanger 13 via the air passage 6a, and is discharged to the outside from the exhaust port 4. During that time, a part of the heat quantity in the return air is recovered by the action of the total heat exchanger 13. Simultaneously with the above, the fresh air outside the room is shown by the solid line woo, and the outside air is sent to the room from the outside air intake 5 through the total heat exchanger 13, the air passage 6b, the air blower room C, and the air supply room A. , Part of the amount of heat is absorbed by the total heat exchanger 13. That is, the above is the case of normal operation, and it is possible to discharge the contaminated air inside the room to the outside and at the same time take in fresh outside air into the room, but the outside air to be introduced into the machine is installed in the heat exchange chamber B. With the cold and hot water heat exchange coils 7 and 8, for example, the cold water heat exchange coil 7 during cooling.
As a result, the cold air can be heated to a proper temperature by the hot water heat exchange coil 8 during heating, and can be cooled and warm air can be easily blown into the room together with the outside air.

Next, when the air conditioning is not required in the four seasons, for example, from May to the beginning of July, or when it is necessary to take in only the cool air from the outside air due to the indoor environment such as indoor sunshine condition and population density, return it. The operation of the exhaust blower 12 is stopped, the supply air blower 11 is operated, and the outside air bypass bus damper 14 is opened to open the outside air from the outside air intake port 5 of the woo shown by the chain line to the heat exchange chamber from the blower chamber C. After passing through B, it passes through the heat exchange chamber B, flows into the air supply chamber A, and can be directly fed into the room from the air supply port 2. Of course, in the above case, the cooling and hot water heat exchange coils 7 and 8 must be stopped from flowing water, but in the unlikely event that the room temperature rises and more cold air is required, Can be solved easily by flowing cold water to the cold water coil 7, and when it is too cold, by opening the hot water heat exchange coil 8 and flowing warm water.

When more appropriate air conditioning by the outside air is required, a part of the return air from the room does not flow out from the exhaust port 4 by adjusting the outside air bypass damper 14 by half-opening or closing. Only the air is discarded outdoors, the remaining amount of the return air is mixed with the outside air introduced into the outside air introduction chamber E, and both are blown into the room as mixed air through the outside air bypass damper 14, or the inside of the room is also dried. However, when proper humidification is required, it is possible to simultaneously feed appropriate humidified air by the action of the humidifier 9. Particularly, in the present invention, since the total heat exchangers 13, 13 are arranged in a plurality of rows in a row, the outside air sucked from one suction port is diverted in several directions on the outlet side. It is possible to supply gentle air that can be subdivided into a room, and at the same time, it is possible to obtain a substantially equal air-conditioning expansion in the room by blowing out from many directions. The heat used is more economically utilized by supplying a part of the heat used in the outside air.

The return air room F is divided into each room. The ventilation passages 6a and 6b are formed by communicating the above chambers. The ventilation passage 6a communicates with the return air inlet 3 and the exhaust outlet 4, and the ventilation passage 6b communicates with the outside air intake inlet 5 and the air supply inlet 2. The air blower passes through the blower passages 6a and 6b vertically, but is crossed in an X shape at 13 places of total heat exchangers, which will be described later. Further, in the heat exchange chamber B, the cold water heat exchange coil 7, the hot water heat exchange coil 8 and other humidifiers 9,
A device such as a drain pan 10 is installed in the blower room C, a blower 11 for air supply is returned in the return air chamber F, and blowers 12 for exhaust air are installed in a substantially vertical line up and down. Filters 15 and 16 for return air and intake air according to the purpose such as a pre-filter and a medium-performance filter near the inside of the inlet 5.
Are arranged so as to be detachable. In addition, it is also possible to use the respective indoor spaces to integrally house the necessary mechanical members such as a control panel and a motorized valve.

In addition, a plurality of total heat exchangers 13 having a vertically elongated rhombic cross section are arranged between the upper and lower air passages 6a and 6b, and in the illustrated example, a plurality of total heat exchangers 13 and 13 are arranged in a row in the left-right direction. The ventilation passages 6a and 6b are connected to each other. Furthermore,
An outside air bypass damper 14 is provided between the exhaust chamber D and the blower chamber C so as to be openable and closable so as to return the air flow in the machine, switch to an arbitrary blowing passage such as exhaust, all outside air cooling, When cooling the outside air, the outside air does not flow to the total heat exchanger 13 because the outside air flows to the Woo path.

Reference numeral 17 in the drawing denotes a front panel which is attached to the front part of the machine body 1 so as to be openable and closable, so that maintenance work such as in-machine inspection and repair can be carried out very easily by opening the door.

It can be used together as a muffling chamber, for example, to reliably prevent and mitigate outflow of noise generated by noise. Further, in some cases, the muffler-equipped blower pipe 19 is attached not only to the air supply port 2 but also to the return air port 3 so as to suppress noise in the cabin flowing out from the return air port 3. Can also be done.

Although the present invention was developed for outdoor installation, it is extremely bulky and can be formed into a vertically long shape. Therefore, by changing only a part of the mechanism, a narrow place in the room,
It can be easily installed and used even for indoor use by utilizing a space such as a gap. Further, depending on the relation of the above-mentioned installation location and the like, it is also possible to attach the upper and lower positions of the air supply port 2 and the return air port 3 to an upside-down body, or to reverse the front and back.

[0016]

As described above, the present invention has the above-mentioned structure. Therefore, by simply switching the outside air bypass damper 14, the return air in the room and the intake of fresh outside air at the same time as the intake of fresh outside air can be used. When cooling is required, complete cooling by all the outside air can be immediately obtained, etc., and it is possible to easily obtain the optimum air-conditioning deployment in the room each time. Of course, the air supply room A, the blower room C, Each chamber of the return air chamber F is formed in a row in a row, and the cold and hot water heat exchange coils 7 are provided in each chamber.
Since the mechanisms such as 8, the drain pan 10 and the blowers 11 and 12 are arranged substantially vertically in the vertical direction, the width can be narrowed, and various mechanical members such as pipes can be easily and compactly accommodated. In addition to the effect, it also has various effects described below.

In particular, in the present invention, as described in claim 2, the total heat exchanger 13 is formed in a rhombic shape having a vertically long cross section, and several total heat exchangers 13 having the vertically long rhombic cross section are arranged in a row in the machine. By arranging it in the above, it is possible to make the entire width very short compared to the one large total heat exchanger that has been used conventionally, and since the weight is also light, the installation area is vast. It can be installed easily and surely without being restricted by any place such as indoors, a small corridor outside the room, a veranda, a wall side, etc. Moreover, each working surface is doubled by several total heat exchangers 13, 13, 13 and the flowing air flow is subdivided so that the most effective heat exchanging action is surely obtained, and the energy used can be greatly reduced. It has a remarkable effect. In addition, the gap between the surfaces of the total heat exchanger 13 naturally diverted and diffused the single-flow air flow introduced from the single suction port, which could achieve a very soft air-conditioning development. .

Further, according to the third aspect of the present invention, by attaching the front panel 17 to the front surface of the machine body 1 so as to be openable and closable, the entire internal mechanism can be immediately seen, and maintenance work for deep inside the machine can be performed. Not only is it performed easily and reliably from outside the room, but at the same time, it has the effect of improving the interior design.

Further, in the present invention, as described in claim 4, a blower pipe 19 in which an appropriate silencing mechanism is previously attached to the air supply port 2 or the return air port 3 which is opened at the back of the machine body 1 It also has the effect of completely preventing and eliminating the noise noise generated in the aircraft from flowing out into the room by connecting them.
