Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention intends to obtain an optimal air conditioning environment in a room by reliably and economically performing not only the ventilation of the room and the introduction of fresh outside air but also the humidification function with one unit. In particular, the present invention relates to a so-called outside air cooling / ventilation unit capable of outside air cooling.

[0002]

2. Description of the Related Art Throughout the four seasons, it is necessary to take in fresh air into the room and to ventilate it in place of the above heating and cooling during the seasons where heating and cooling are not required, for example, from April to June. Normally, as the structure of this type of ventilation unit, the indoor intake part and the outside air introduction part are composed of different structures, so even if the above is formed with the same structure, it is a small cabin. It is extremely difficult to accommodate and arrange a large number of mechanical devices having completely different functions such as intake and exhaust, including the total heat exchanger, in view of the space, and it is very difficult to cool the outside air in the ventilation unit having such a structure. It is completely impossible to form a by-pass passage for use. Further, if the above-mentioned outside air and air supply by-pass passages are provided outside the unit main body, there is a problem that the overall shape becomes very bulky and a vast installation area is required.

[0003]

In view of the above-mentioned drawbacks, the present invention is capable of simultaneously performing all the work of sucking indoor air and exhausting air through one season with a single unit device, and particularly enables the outside air cooling at the beginning. Its main purpose is to provide an outdoor air-cooling and ventilation unit that is most suitable as an energy-saving machine for which a refreshing indoor environment is required.

[0004]

As means for achieving the above-mentioned object, the outdoor air cooling and ventilation unit according to the present invention has a total heat exchanger chamber 2 at the center of the inside of a machine body 1 as shown in the illustrated example.
And a partition plate B on both left and right sides of the total heat exchanger chamber 2.
At B, the air supply chamber 4, the return air chamber 5, the exhaust chamber 6, and the outside air introduction chamber 7
Each of the chambers is divided and formed, and an air supply port 8, a return air port 9 and an outside air intake 10 and an exhaust port 11 are formed in the upper part of the machine body 1 and a ventilation passage A communicating with each of the intake and exhaust ports. , A are formed in a substantially U shape in the machine with the total heat exchanger chamber 2 as an axis, and a return air blower 12 and an exhaust blower 13 are provided in the respective chambers.
In a floor-standing ventilation unit in which necessary mechanical members such as a heat exchange coil 14 and a humidifier 15 are appropriately arranged and arranged, a total heat exchanger 3 is manually or manually operated inside the total heat exchanger chamber 2. A vertical support is provided so as to be rotatable left and right, and when the total heat exchanger 3 is rotated, outside air is provided before and after the total heat exchanger 3,
It is configured to form the bypass paths C, C for supplying air. Further, as a means for obtaining a muffling function, a muffling chamber 20 is formed by appropriately opening the intake port 8, the return port 9, the outside air intake port 10, and the exhaust port 11 above the unit body. It is needless to say that a better sound deadening effect can be expected and obtained by integrally connecting them.

[0005]

Operation: The ventilation unit is installed and installed in a predetermined place such as indoors or outdoors, and is provided with an air supply port 8,
Return air port 9 to indoor side, outside air intake 10, exhaust port 11
Blower 1 for exhaust and exhaust of each of which is connected to a duct or directly communicates with the inside and outside of the room and is returned when intake and ventilation are required.
By operating 2 and 13, the polluted air in the room flows from the return air port 9 into the return air chamber 5, which flows through the ventilation passage A while part of the heat quantity is absorbed by the total heat exchanger 3 and the exhaust port. 11
More released outdoors. At the same time as the above action,
Fresh air outside is sucked into the machine through the outside air intake 10 and flows into the total heat exchanger 2 through the outside air introduction chamber 7, while a part of the indoor heat amount that can be absorbed is recovered while the blower passage A
The air is sent to the air supply chamber 4 via the heat exchanger, and the whole amount is mixed by the switching operation of the damper, or the heat exchange coil 12 and the humidifier 15 which are mixed with a part of the exhaust gas and are installed in the air supply chamber 4 have an appropriate temperature. Cooling and warming air is supplied from the air supply port 8 to the room while humidifying. However, when indoor cooling or heating is not required as in the indoor temperature environment or the seasons such as June and July, the total heat exchanger 3 is moved to the left or right by a mechanical force such as an electric motor or manually operated. By rotating at 45 °, the bypass passages C, C for outside air and air supply are immediately opened in the front and rear units of the total heat exchanger 3, and the outside air is taken in through the bypass passages C, C before and after. It is possible to supply fresh outside air from the inlet 10 directly to the room without passing through the total heat exchanger 3 and the heat exchange coil 14. That is, in Fig. 3, the air flow during the outside air cooling operation is shown in Fig. A, and the air flow in the normal heat exchange operation is shown in Fig. A.
