The present invention was developed for the above purpose, and its outline will be described with reference to the illustrated example. A return port is provided in the upper portion of a machine body 1 having a vertically long overall shape. 2 and the blower port 3, and an exhaust port 4 and an outside air intake port 5 are provided on one side, respectively, and the return air port 2 and the exhaust port 4 and the outside air intake port 5 and the blower port 3 are connected to the upper and lower ventilation paths A and B, respectively. In the upper air passage A, an exhaust air blower 6 is provided substantially in the center of the airframe, and in the lower outside air air passage A, a hot water coil 7, a humidifier 9, a filter 10, an electrostatic precipitator 1 are connected.
1, mechanical devices such as 1 and an outside air blower 8 are arranged, and a bypass air blowing passage C is formed between the exhaust port 4 and the outside air intake port 5, and a return air switching damper a is provided in the bypass air blowing passage C. , The outside air blowing damper b in the outside air blowing passage B
Are provided so as to be openable and closable, respectively, and by the switching action of each of the blower dampers, not only the introduction of the outside air but also the mixed air with the return air in the room can be arbitrarily fed into the room.

[0005]

Next, the operation will be described. An air conditioner having the above-described structure is installed at a predetermined location in the room, and the upper air return port 2 and the air blower port 3 are provided on the indoor side by duct connection. Connect to the return air and suction port. By simultaneously driving the exhaust blower 6 and the outside air blower 8 in such a state, the indoor air is discharged from the return air port 2 to the outside of the exhaust air from the exhaust port 4 through the ventilation passage A in the machine. On the other hand, the fresh outside air introduced from the outside air intake port 5 is blown into the room through the outside air blowing passage B from the blowing outlet 3 while the cold and hot water coil 7 installed in the blowing passage B keeps the temperature at an appropriate temperature. Heat exchange is performed and it is possible to send cold or warm air of a predetermined temperature to the inside of the room. In addition, at the time of operation, the exhaust port damper a and the outside air port damper b are opened,
The return air switching damper c is closed. According to the above, the whole amount of the contaminated air in the room is discharged from the exhaust port 4 at the same time as the introduction of the outside air. However, when a part or the whole amount of the room air is blown in the direction of the outside air blowing passage B on the blower side, the bypass air is blown. By opening the return air switching damper c in the passage C,
The recirculated air from the return air port 2 again flows into the outside air blowing passage B and is mixed with the outside air introduced from the outside air intake port 5, so that the heat energy in the return air can significantly reduce the thermal energy. It can be used economically effectively. Further, by adjusting the opening / closing operations of the exhaust port damper a, the outside air port damper b, and the return air switching damper c, it is possible to easily and surely obtain the expected air volume.

Further, in the present invention, a muffler chamber 13 is integrally provided with a return air outlet 2 and a blower outlet 3 in the upper portion of a vertically long machine body 1 and an appropriate muffling mechanism 12 provided therein. By mounting and connecting, the air passage A and the outside air air passage B both formed inside the machine are formed to be long, and the noise in the air circulating in the air passages A and B is eliminated together with the noise. It is possible to demand a reliable silencing function.

[0007]

Embodiments of the present invention will now be described with reference to the drawings, in which 1 is a vertically long airframe, and a return air port 2 and a blower port 3 are provided on the upper portion, and appropriate portions such as the back and sides of the airframe are provided. An exhaust port 4 and an outside air intake port 5 are provided in each. In addition, an exhaust air blowing passage A communicating the return air outlet 2 and the exhaust outlet 4 and an outside air blowing passage B communicating the outside air intake 5 and the blowing outlet 3 are formed in the machine, and the exhaust air passage A is exhausted. The blower 6 and the blower 8 for outside air are installed in the outside air blowing passage B. The exhaust blower 6 opens the discharge port in the blow passage A toward the exhaust port 4, and the outside air blower 8 has the discharge port at the innermost portion in the outside air blow passage B. Further, various mechanical devices such as a cooling and hot water coil 7, a humidifier 9, a filter 10, and an electrostatic precipitator 11 are installed in the air passage B, respectively. Further, a bypass air blow passage C is formed between the exhaust port 4 and the outside air intake 5, a return air switching damper c is installed in the blow passage C, and a return air air in the exhaust blow passage A is operated by switching the damper c. A part or all of the above is recirculated into the outside air blowing passage B. Further, an exhaust port damper a is attached to the exhaust port 4, and an external air port damper b is attached to the outside air intake port 5 so as to be openable and closable, and the external air is introduced not only by the switching operation of these dampers.
Therefore, it is possible to supply the cold air and the warm air, which are mixed with the return air in the room, depending on the room.

Further, in the present invention, when the exhaust blower 6 is installed inside each of the blower passages A and B, for example, in the blower passage A, substantially in the center of the airframe, the outside blower air is blown below the exhaust blower 6. In the passage B, cold, hot water coil 7, humidifier 9,
By disposing the comparatively heavy mechanical devices such as the filter 10 and the electrostatic precipitator 11 so as to be gathered substantially coaxially with each other in the center of the machine body, it is possible to stably install even the vertically long machine body.

By doing so, a better muffling function can be mentioned.

[0010]

As described above, according to the present invention, the entire body is formed in a vertically long shape as compared with a conventional air conditioner which requires a horizontal width and is bulky. Therefore, the installation area is very small. It can be easily and surely installed in any narrow place, and the vertical shape allows the ventilation passage to be formed inside the machine to be very long, so it is possible to naturally and reliably eliminate the noise caused by exhaust as well as indoor ventilation. It has the effect of being able to do so.

Further, as described in claim 2, a relatively heavy mechanical device such as an exhaust air blower 6, a cooler, a hot water coil 7, a humidifier 9, a filter 10, an electrostatic precipitator 11 and the like is arranged on the substantially central coaxial inside the machine. By arranging and arranging all of them together, it has an effect that it can be installed stably regardless of how long the aircraft is.

Further, as described in claim 3, by integrally mounting and connecting the sound deadening chamber 13 having the sound deadening mechanism 12 on the upper portion of the machine body 1, the sound deadening effect due to the vertically long shape is further improved. It is possible to request a very quiet air-conditioning deployment such as being able to request a noise reduction effect.
