1 is an overall configuration diagram of an air conditioner system according to an embodiment of the present invention.

Referring to FIG. 1, the air conditioner system includes a plurality of diffusers 100, a dehumidifying air conditioner 200, and a supply pipe 110 and a return pipe 120 that connect a flow of air therebetween.

The diffuser 100 is a device for supplying air to the room, and in one embodiment, a plurality of spaced apart at predetermined intervals on the indoor ceiling is installed. The dehumidification air conditioner 200 is to strengthen the dehumidification function in a conventional air conditioner, and may perform cooling, heating, air purification, and dehumidification functions.

In this configuration, the air that is air-conditioned in the dehumidifying air conditioner 200 is supplied to each diffuser 100 through the supply pipe 110, the air is discharged to the room through the discharge port of the diffuser 100, the indoor air is Returned to the dehumidification air conditioner 200 through the return pipe 120 is discharged to the outside of the building.

On the other hand, Figure 1 is a brief illustration of the air conditioner system, strictly speaking, the diffuser 100 is an air supply diffuser for supplying air from the air conditioner 200 through the supply pipe 110 to the room, the return pipe 120 Is connected to a separate ventilation diffuser (not shown) installed in the room, through which the indoor air is returned to the air conditioner (200). However, those skilled in the art will fully understand the air supply / ventilation structure from the schematic diagram of FIG.

Hereinafter, the diffuser 100 and the dehumidification air conditioner 200 will be described in detail with reference to FIGS. 2 and 3.

Figure 2a is a perspective view of a diffuser according to an embodiment of the present invention, Figure 2b is a cross-sectional view of the diffuser according to an embodiment of the present invention.

2A and 2B, the diffuser 100 according to an embodiment is a device for supplying air that is air-conditioned from the air conditioner 200 to the interior of a building. The duct connector 11, the cooling coil 12, and the discharge port are provided. 13, an air inlet 14 may be included.

The diffuser 100 may be embedded in the ceiling of the room as shown in FIG. 2B so that only the bottom surface of the diffuser 100 may contact the indoor space. However, depending on the embodiment, the diffuser 100 may be partially embedded in the ceiling or not embedded at all.

The duct connector 11 is a pipe through which the air conditioned from the air conditioner 200 passes, and is disposed to penetrate from one end to the other end of the diffuser along the longitudinal direction of the diffuser at the top of the diffuser 100. In one embodiment, the duct connector 11 is directly or indirectly connected to the supply pipe 110 shown in FIG.

At least one discharge port 13 is formed at a bottom surface of the diffuser 100 to form a passage for discharging air conditioned to the room. In the illustrated embodiment, two outlets 13 are formed on the bottom of the diffuser 100 in the longitudinal direction of the diffuser. However, the discharge holes 13 may be formed at various positions of the diffuser in various shapes. .

In one embodiment, the duct connector 11 inside the diffuser 100 includes one or more through holes or through slots, which are connected to the discharge holes 13. Accordingly, as shown in FIG. 2B, the air-conditioned air supplied from the air conditioner 200 exits the outside of the duct connector 11 through the through hole or the through slot of the duct connector 11 to discharge the discharge port 13. Through the diffuser.

The cooling coil 12 is a pipe through which cold water passes, and is disposed along the longitudinal direction of the diffuser under the duct connector 11. That is, the lower side of the duct connector 11 may be disposed in parallel with the duct connector (11).

As shown in the illustrated embodiment, the cooling coil 12 may be composed of a plurality of pipes, but the number of pipes is not limited to a specific value.

Cold water passes through the cooling coil 12, thereby cooling the air passing near the cooling coil 12. In one preferred embodiment, the cooling coil 12 is directly or indirectly connected to the air conditioner 200, so that the cold water used and discarded in the air conditioner 200 may be used as the cold water of the cooling coil 12, an alternative embodiment. In, the cold water used once in another air conditioner or cooling device may be used as the cold water of the cooling coil 12.

In an alternative embodiment, the diffuser 100 may include a heating function, in which case the cooling coil 12 may flow hot water, not cold water. That is, according to the embodiment, cold water may flow into the cooling coil 12 (summer season), or hot water may flow (winter season). Thus, "cooling coils" may be referred to as "coils" in the sense of including such alternative embodiments. However, in the detailed description and drawings of the present specification, the cooling function is described as an example, so it will be referred to as a "cooling coil".

At least one air inlet 14 is formed at the bottom of the diffuser 100, and forms a passage through which indoor air flows into the diffuser 100. In a preferred embodiment, the air inlet 14 is formed just below the cooling coil 12.

By the configuration of the cooling coil 12 and the air inlet 14, some of the indoor air can be cooled again by the diffuser 100. That is, in order to supply the air air-conditioned from the air conditioner 200 to the room, the air outlet 13 must pass through the air outlet. In this case, since the speed of the air flowing from the duct connector to the air outlet 13 is high, the Venturi effect is caused. The pressure of the discharge port 13 is lower than the surroundings, whereby the air near the cooling coil 12 also flows into the discharge port 13. That is, as indicated by the arrows in FIG. 2B, the indoor air near the air inlet 14 is slightly cooled while passing through the space with the cooling coil 12, and then flows into the inlet of the discharge port 13 and is discharged again into the room. do.

For example, when the indoor temperature of the summer is about 24 degrees by the above operation is as follows.

First, it is assumed that air that is air-conditioned between about 15 to 18 degrees from the air conditioner 200 is provided to the duct connector 11 of the diffuser 100, and the cold water supply temperature of the cooling coil 12 is about 14 to 16 degrees. If the indoor temperature is 24 degrees on average, the temperature near the indoor ceiling where the diffuser 100 is located is approximately 25 to 26 degrees, and the air near the indoor ceiling is cooled through the air inlet 14 of the diffuser 100. It rises to (12) side. This air is slightly cooled by the cooling coil 12 and is mixed with air directed from the duct connector 11 to the discharge port 13 by the Venturi effect, and consequently, approximately 20 degrees through the discharge port 13. Air having a temperature may be provided indoors.

Thus, the diffuser 100 according to an embodiment of the present invention, in addition to the configuration of the duct connector 11 and the discharge port 13 for supplying the air to the room, the cooling coil 12 for cooling the indoor air It includes, there is an advantage that can handle a relatively large cooling load.

On the other hand, in the case of the diffuser 100 using the cooling coil 12, condensation may occur in the diffuser during a high humidity season or a sudden increase in latent heat load, such as during the rainy season. That is, when the high humidity indoor air near the cooling coil 12 is in contact with the cooling coil 12, the temperature drops below the dew point, and moisture contained in the indoor air is condensed with water droplets.

Therefore, for example, in order to prevent condensation from occurring on the cooling coil 12 of the diffuser 100, the cold water temperature flowing in the cooling coil 12 must be higher than the dew point temperature of the indoor air, and the surface of the diffuser 100 is To prevent condensation from occurring, the dew point temperature of the air inside the diffuser should be lower than the surface temperature of the diffuser.

In order to prevent condensation of the cooling coil 12 of the diffuser, for example, assuming that the indoor air temperature in summer is 24 degrees and the relative humidity is 50%, the dew point temperature of this indoor air is 12.98 degrees. Therefore, for example, considering a margin of about 0.5 degrees, the temperature of the cold water supplied to the cooling coil 12 should be 13.5 degrees or more, preferably about 14 degrees.

On the other hand, in order to lower the dew point temperature of the air inside the diffuser to prevent condensation on the surface of the diffuser, by combining the dehumidifying air conditioner 200 as shown in Figure 3 with the diffuser 100 in a preferred embodiment, To supply air having a diffuser (100).

Figure 3 is a block diagram showing the configuration of a dehumidification air conditioner according to an embodiment of the present invention.

Referring to FIG. 3, the dehumidifier air conditioner 200 according to an embodiment includes filters 21 and 26, a total heat exchanger 22, an air conditioner 23, a dehumidifier 24, and a blower 25. 27).

The filters 21 and 26 respectively filter air (outdoor air) introduced into the air conditioner from outside and air (return: air) introduced into the air conditioner from inside, respectively, and the blowers 25 and 27 are air conditioners. Air is supplied to the room (supply air) and to the outside air (exhaust air) respectively.

The total heat exchanger 22 serves to recover the thermal energy of the air going from the indoor to the outdoor. That is, by recovering heat of the exhaust by exchanging heat between the outside air introduced into the air conditioner 200 and the exhaust gas before the air conditioner 200 is discharged, the temperature and humidity of the outside air introduced into the air conditioner 200 can be lowered.

The cooling device 23 serves to lower the temperature of the outside air introduced into the air conditioner 200. Various conventionally known methods may be used to cool the outside air, and in one embodiment, the air conditioner 23 includes a conduit through which cold water flows and the outside air may flow between these conduits to lower the temperature of the outside air.

And the illustrated embodiment has been described as an example of the case of cooling, on the contrary, in the case of heating the room can be replaced by a heating device instead of the cooling device 23 is a matter of course.

In one preferred embodiment of the present invention, the air conditioner 200 includes a dehumidifier 24. In one preferred embodiment, a rotary desiccant-coated dehumidification wheel may be used as the dehumidifier 24. The desiccant coating absorbs moisture from the outside air introduced into the air conditioner 200, and when the ventilation introduced into the air conditioner 200 passes through the dehumidification wheel, the absorbed moisture is discharged to the ventilation. Accordingly, the dehumidifier 24 serves to lower the humidity of the outside air by exchanging latent heat energy (eg, humidity) between the ventilation introduced into the air conditioner 200 and the outside air.

Also in a preferred embodiment the dehumidifier 24 is a passive dehumidifier.

Conventionally, cooling coil systems or active dehumidification systems have been used. In the cooling coil system, a refrigerating device and a boiler device are required because the air must be supercooled by using a cooling coil to re-humidify the air and then reheated to a predetermined temperature. Since it is necessary to continuously spray the steam supply device, all conventional methods have a disadvantage that requires a lot of system installation and operating costs.

However, the passive dehumidifier according to an embodiment of the present invention can obtain a dehumidification effect by the coating property of the wheel, so that it is possible to obtain stable dehumidification performance without the need for any accessory equipment, and also to reduce the initial installation or operating cost of the device. have.

By the configuration of the dehumidifying air conditioner 200 of FIG. 3 as described above, the outdoor air introduced from the outside is cooled and dehumidified while passing through the heat exchanger 22, the air conditioner 23, and the dehumidifier 24. It is supplied to each diffuser 100 in the building interior through the supply pipe 110 as shown in FIG.

Meanwhile, those skilled in the art will understand that the block diagram shown in FIG. 3 is only one example of a dehumidifying air conditioner. In the case of heating the room, a heating device may be used instead of the air conditioner 23, and the position or arrangement order of each component such as the filters 21 and 26 and the blowers 25 and 27 may be changed according to embodiments. In addition, components not shown in FIG. 3 may be added as necessary.

Figure 4 is a wet air diagram for explaining the change in temperature and humidity of the air by the operation of the air conditioner system according to an embodiment of the present invention.

In the illustrated wet air diagram, the horizontal axis represents air temperature and the vertical axis represents absolute humidity of air. The numerical values of temperature and absolute humidity in the graph are one example for explaining the effect of the air conditioner system according to the present invention, and it will be understood that the numerical values may vary within a predetermined range according to the embodiment.

Referring to FIG. 4, the air located at "a" on the graph represents outdoor air before entering the air conditioner 200. As shown, the air temperature and absolute humidity are assumed to be 31 degrees and 19g / kg, respectively.

Arrows in the direction of "a" to "b" in the graph indicate that air of "a" flows into the air conditioner 200 and heat exchange is performed by the total heat exchanger 22. It can be seen that both the temperature and the humidity are reduced by a predetermined amount as a result of the heat exchange of the total heat exchanger 22. After that, the air passing through the total heat exchanger 22 (air of "b" in the graph) is cooled while passing through the air conditioner 23. That is, as shown in the graph of FIG. 4, when the temperature of "b" decreases while the temperature decreases, both temperature and humidity decrease along the saturation line.

After the air is cooled to the point "c" by the air conditioner 23, this air is dehumidified through the dehumidifier 24, and thus the humidity decreases along the isenthalpy line on the graph and moves to the point "d". do. Therefore, it can be seen that the outside air at the point "a" reaches the point "d" by being introduced to the air conditioner 200 and air-conditioned, and the air at this time may have a temperature of approximately 17 degrees and an absolute humidity of 5 g / kg. And the air-conditioned air is supplied to the duct connector 11 of each diffuser 100 through the supply pipe (110 in Figure 1) as supply air (supply air).

On the other hand, the air at point "e" in FIG. 4 represents air near the ceiling of the building interior. For example, if the room temperature is about 24 degrees, the air near the ceiling is assumed to be about 25 degrees. This air flows into the air inlet 14 of the diffuser 100 as described with reference to FIG. 2 and is cooled by the cooling coil 12 to move to the "f" point on the graph.

Then, due to the Venturi effect, the air cooled by the cooling coil 12 (that is, the air at the point “f” in the graph) is released from the duct connector 21 (that is, the air at the point “d” in the graph). ) Is finally discharged into the room through the discharge port 13, the air at this time has a temperature and humidity at any point between the "d" and "f" on the graph according to the mixing ratio. In the graph shown as an example, it can be seen that air having a point “g”, that is, a temperature of about 20 degrees and an absolute humidity of 8 g / kg is discharged from the diffuser 100.

By the air conditioner system according to an embodiment of the present invention as described above may have the following effects.

-Draft Problem Solving: The diffuser 100 according to the present invention has a low discharge rate of air, there is no draft can be built a comfortable and comfortable indoor environment.

-Noise Reduction: The diffuser 100 according to the present invention has no motor or a blower fan, so the noise is significantly reduced.

-Inexpensive equipment and maintenance costs: The diffuser 100 according to the present invention utilizes the basic properties of the fluid, such as the venturi effect and the convection effect, so that there are no parts such as a motor and the structure is simple, thereby reducing product installation and maintenance costs. have.

-Prevention of dew condensation: The diffuser 100 and the dehumidification air conditioner 200 according to the present invention can be combined to supply air having low absolute humidity to the room, and thus, when the humidity is high in season or latent heat load, such as during the rainy season. Even in the diffuser 100, no condensation occurs.

Although the present invention as described above has been described by way of limited embodiments and drawings, the present invention is not limited to the above embodiments, and those skilled in the art to which the present invention pertains various modifications and variations from this description. This is possible. Therefore, the scope of the present invention should not be limited to the embodiments described, but should be defined by the utility model registration claims to be described later and equivalents thereof.
