Relates to an air conditioning system.

In general, when a living organism breathes for a certain period of time in a space that is blocked from outdoor air, the amount of carbon dioxide increases in the room, which interferes with the living breathing. Therefore, indoor space should be ventilated frequently in a space where many people stay together, such as an office, or in a narrow space such as a vehicle. At this time, a commonly used ventilation system.

In detail, the ventilation system is generally a device that is installed on the indoor floor or fixedly mounted on the ceiling, such that outdoor air is introduced into the room and indoor air is discharged to the outside. Therefore, the installation of the ventilation system is required in a space where the circulation of indoor air is not smooth or a space where many people stay.

However, in the conventional general ventilation system, only a clean device for cleaning indoor air or a ventilation device for circulation of indoor air and outdoor air is installed. In other words, when the ventilation device is operated in winter when the temperature difference between the outdoor air and the indoor air is remarkable, there is a problem that the indoor temperature is lowered and the heating efficiency is significantly lowered.

In addition, there is a problem in that a separate air conditioner such as an air conditioner or a heater is additionally operated in order to increase or decrease the temperature of each indoor space partitioned while the ventilation device is operated.

In addition, conventionally, since the air discharged from one ventilation device is to be spread to a plurality of compartments, the ventilation efficiency is inferior to the volume.

In addition, when partitioned into a plurality of rooms in a building in order to maintain the indoor environment of each room separately, there is a problem that a separate ventilation device or cooling device, etc. must be provided in each room. In other words, there is a disadvantage in that each indoor space is maintained in a different air conditioning environment, such as to maintain a cooling state in one room and to perform only a ventilation function in another room.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide an air conditioning system in which the air discharged from one ventilation device is spread into a plurality of partitioned indoor spaces, thereby increasing the ventilation efficiency relative to the volume. It is done.

In addition, an object of the present invention is to provide an air conditioning system in which the indoor environment of each room is maintained separately when partitioned into a plurality of rooms in a building.

An air conditioning system according to the present invention for achieving the object as described above is an electrothermal heat exchanger for allowing the outdoor air to be sucked out and the indoor air discharged; Directly or indirectly connected to the heat exchanger, the discharge grill is provided with a discharge grill, a fan for sucking indoor or outdoor air, a filter for purifying the air sucked, and is attached to one side of the discharge grill; A ventilation cleaning device including an installation case in which an inlet and an outlet are formed; A cold / hot air supply device which is directly or indirectly connected to the electrothermal heat exchanger or the ventilation cleaner, and includes an indoor unit for supplying cold air or hot air to the room, and an outdoor unit for exchanging outdoor air and refrigerant; And a diffuser connected directly or indirectly to the electrothermal heat exchanger or the ventilation cleaner or the cold / hot air supply device.

By the above configuration, the air discharged from one ventilation device or one total heat exchanger is distributed to a plurality of indoor spaces, and there is an effect of maintaining a separate indoor environment for each space.

Then, it passes through the discharge grill 141 and is finally discharged to the room.

Meanwhile, while the outdoor air is sucked through the air supply duct 31, the indoor air contaminated through the exhaust duct 32 is discharged to the outside.

8 is a bottom perspective view illustrating the flow of air in a clean mode according to the spirit of the present invention.

Referring to FIG. 8, when the clean mode is selected, indoor air is sucked through the indoor intake port 111. In addition, the suctioned indoor air is purified while passing through the filter 13 and then discharged back to the room through the discharge grill 141 of the discharge grill 14.

On the other hand, when the clean mode is selected, the inlet 173 connected to the air supply duct 31 may be shielded.

In detail, since the clean mode is selected and the fan 15 is rotated, air is not sucked toward the exhaust grill 148, and thus it is not necessary to provide a separate blocking member on the exhaust port 172 side. However, since the intake port 173 communicates with the filter 13, there is a possibility that outdoor air is also sucked together when indoor air is sucked through the indoor intake port 111.

Thus, in order to completely block the inflow of external air through the inlet 173 connected to the air supply duct 31 in the clean mode and to perform only a pure clean function, the inlet 173 is selectively selected according to a specific mode. The opening and closing device to open and close may be provided.

On the other hand, when the flow of the air in more detail in the clean mode, first, the indoor air is sucked through the indoor intake port 111 by the drive of the fan (15). The sucked indoor air is filtered while passing through the filter 13, and passes through the orifice 143 to reach the fan 15. Then, the air reaching the fan 15 is dispersed in the horizontal direction, guided by the air guide 144 is discharged back to the room through the discharge grill 141.

In detail, the exhaust inlet 42 is formed at the same side as the air supply outlet 43, and the exhaust outlet 44 is formed at the same side as the air inlet 45. The position of the exhaust inlet 42 and the air supply outlet 43 or the positions of the exhaust outlet 44 and the air supply inlet 45 may vary depending on the type of the total heat exchanger 40.

In more detail, the exhaust inlet 42 is connected to the exhaust connection pipe 34 to allow the indoor air discharged from the ventilation cleaner 10 to flow. In addition, the air supply discharge port 43 is connected to the air supply connection pipe 33 to allow the outdoor air to be supplied to the ventilation cleaner 10.

In addition, when the exhaust fan 47 is operated, indoor air introduced into the heat exchanger 40 through the exhaust inlet 42 is discharged to the outside through the exhaust outlet 44. When the air supply fan 46 is operated, outdoor air sucked into the air supply inlet 45 is introduced into the ventilation cleaning apparatus 10 through the air supply outlet 43 and discharged into the room. In addition, the indoor air introduced through the exhaust intake port 42 and the outdoor air sucked through the air supply intake port 45 exchange heat while passing through the electrothermal exchange element 41.

In addition, outdoor air introduced into the ventilation cleaner 10 by passing through the air supply discharge port 43 is purified while passing through the filter 13, and the discharge grill 141 of the discharge grill 14 is removed. It is discharged to the room through. In addition, the indoor air sucked through the exhaust grill 148 is introduced into the total heat exchanger 40 through the exhaust duct 32 and the exhaust suction port 42.

12 is an exploded perspective view showing a duct member according to the spirit of the present invention.

Referring to FIG. 12, the duct member 30 according to the present invention includes an air supply duct 31 through which outdoor air is sucked in, and an exhaust duct 32 through which indoor air is discharged.

In detail, the duct member 30 includes a straight straight tube 312 and 322 having a predetermined length, elbows 313 and 323 that are curved with a predetermined curvature, the straight pipes 312 and 322 and a straight tube 312 and 322. Or a homogeneous connector 301 connecting the elbows 313 and 323 and a release connector 314 and 324 connecting the straight pipes 312 and 322) or the elbows 313 and 323 to the heat exchanger 40. The duct member 30 is supported by the hanger 302 on the ceiling portion.

13 is a first embodiment showing an air conditioning system according to the spirit of the present invention, FIG. 14 is a second embodiment showing an air conditioning system according to the spirit of the present invention, and FIG. 15 is an air according to the spirit of the present invention. A third embodiment showing a harmonic system.

Referring to FIG. 13, the ventilation cleaning apparatus 10 according to the present invention is connected to the heat exchanger 40 by the duct member 30, and the heat exchanger 40 and the ventilation cleaning apparatus 10 are the same indoor space or the like. Can be installed in other interior spaces. In other words, the heat exchanger 40 is attached to the wall partitioning the indoor and outdoor, so that the outdoor air flows directly into the heat exchanger 40. In addition, when the indoor space in which the ventilation clean device 10 is installed is formed in the interior of the building, the heat exchanger 40 and the ventilation clean device 10 are connected to each other by using the duct member 30. And the linear pipe 312, the elbow 313, etc. which comprise the said duct member 30 are arrange | positioned suitably according to the installation position of the said ventilation cleaning apparatus 10.

In addition, the air supply connecting pipe 33 is formed so that the end is divided in two directions as shown, one end is connected to the air supply duct 31 and the other end is connected to the diffuser 70. In addition, an end of the diffuser 70 may be located in another independent space in which the heat exchanger 40 or the ventilation cleaner 10 is not installed. Then, the connection pipe 71 is branched from one point of the diffuser 70, and the air conditioner 80 is connected to the connection pipe. In addition, the air conditioner 80 may be installed in an independent space similarly to the diffuser 70 so that each indoor space may be maintained independently of each other.

According to the configuration as described above, the outdoor air introduced through the heat exchanger 40 is discharged to the space in which the ventilation cleaning device 10 is installed, and the indoor air is discharged to the outside through the exhaust duct 32. . In addition, in the clean mode, the indoor air is purged by the filter 13 while being introduced into the ventilation cleaner 10, and then discharged back into the room. The outdoor air sucked through the heat exchanger 40 is immediately discharged in the space where the diffuser 70 is installed. Here, in the heat exchanger 40, the outdoor air sucked out and the indoor air discharged are heat exchanged.

On the other hand, the connector 71 is to be connected to the indoor unit or outdoor unit of the air conditioner (80). In detail, when the connection pipe 71 is connected to the indoor unit of the air conditioner 80, the heat exchanger is primarily heat exchanged inside the heat exchanger 40 in the process of introducing outdoor air through the heat exchanger 40 to lower the outdoor temperature. In the state is introduced into the indoor unit of the air conditioner (80). And, although not shown in the drawings, when the connection pipe 71 is connected to the outdoor unit of the air conditioner 80, the efficiency of the outdoor heat exchanger is much better than the conventional outdoor unit.

In other words, the outdoor air introduced through the heat exchanger 40 maintains a lower temperature than the outdoor temperature because it heat exchanges with the indoor air discharged from the inside of the heat exchanger 40. The outdoor air flowing into the outdoor unit of the air conditioner 80 along the air supply connection pipe 33 and the connection pipe 71 exchanges heat with an outdoor heat exchanger installed in the outdoor unit.

Here, the conventional air conditioner outdoor unit is generally heat exchanged by direct contact with the outdoor air and the outdoor heat exchanger. However, as proposed in the present invention, since the outdoor air that is primarily heat exchanged through the heat exchanger 40 to maintain a state lower than the outdoor temperature is heat-exchanged with the outdoor heat exchanger, the heat exchange efficiency is further improved.

In addition, instead of the air conditioner 80, the connection pipe 71 may be equipped with a hot air heater or a combined air-conditioning and heating air conditioner. In detail, the warm air fan is also composed of an indoor unit and an outdoor unit, and the connection pipe 71 is connected to the indoor unit or the outdoor unit of the warm air fan, so that the outdoor air sucked is exchanged with the indoor heat exchanger or the outdoor heat exchanger. In more detail, when the connecting pipe 71 is connected to the outdoor unit of the warm air fan, the outdoor air sucked through the connecting pipe 71 exchanges heat with the indoor air discharged from the inside of the heat exchanger 40, thereby making the outdoor temperature. It will stay higher. Therefore, since the refrigerant flowing in the outdoor heat exchanger absorbs more heat from the sucked outdoor air, the heat exchange efficiency is better than in the conventional case. In the embodiment presented below, it can be seen that a hot air heater or the like may be mounted at a position where the air conditioner 80 is mounted, as in the present embodiment, and a redundant description will be avoided.
