Moisture is removed by passing through the dehumidifying rotor 130 , and air having a temperature higher than before through the removal of moisture may be supplied to the evaporative cooler 113 using the dehumidifying fan 112 .

At this time, the dehumidified air supplied through the dry channel of the evaporative cooler 113 performs heat exchange with the air discharged through the wet channel of the evaporative cooler 113 and is cooled, compared to when it flows into the evaporative cooler 113 . It can be low temperature dehumidified air.

The inside of the evaporative cooler 113 is composed of a dry channel and a wet channel, and a first water injection module may be further provided in the wet channel to supply moisture to the air flowing through the wet channel. When water is sprayed on the air flowing through the wet channel, the sprayed water evaporates and cools the plate surrounding the wet channel to cool the air flowing through the dry channel.

In addition, the second water injection module may supply moisture by injecting water into the air passing through the evaporative condenser 114 . The evaporative condenser 114 passes the cooled air from the evaporative cooler 113 to reduce the internal temperature of the condenser generated when condensing the refrigerant. For example, the temperature inside the condenser is reduced from 50 degrees to 30 degrees by spraying water into the cooling and dehumidified air passing through it, thereby preventing excessive rise in temperature to reduce power consumption and increase energy efficiency. The above-described first water injection module and the second water injection module may include a water pump for supplying water and a spray nozzle for spraying water supplied by the water pump, and the indoor temperature may be controlled by the operation of the water pump. . Alternatively, the direct water pressure of the water may be used instead of the water pump. In this case, the water pump is not required, and the water injection can be controlled by the opening/closing operation of the direct water valve.

By further including, it is possible to achieve overall energy efficiency as well as cooling efficiency. Specifically, the COP of the conventional air conditioner is only 3.1 to 3.7, but according to an embodiment of the present invention, it can be seen that the COP reaches 5.5 to maximize the cooling efficiency, and the condensation temperature of the evaporative condenser 114 is lowered. Energy efficiency is maximized by reducing power consumption by using latent heat while lowering it.

In addition, the heating unit 121 is provided in the second flow path 120 to heat the introduced external air with hot water and supply it to the dehumidifying rotor 130 , thereby providing the air contained in the second region 132 of the dehumidifying rotor 130 . The drying rate of the dehumidifying rotor 130 may be increased by evaporating moisture. For example, the heating unit 121 may be a hot water coil.

The dehumidifying fan 112 is provided in the first flow path 110 to flow the air that has passed through the first area 131 of the dehumidifying rotor 130 into the room, and the regeneration fan 122 is provided in the second flow path 120 . provided so that the air that has passed through the second region 132 of the dehumidifying rotor 130 can flow to the outdoors.

The extraction fan 115a and the condensing fan 115b may be operated so that the wet channel of the evaporative cooler 113 and the air discharged from the evaporative condenser 114 are discharged to the outside (EA).

Air flowed (OA) from the outdoors to the room through the first flow path 110 passes through the dry channels of the dehumidifying rotor 130, the dehumidifying fan 112, and the evaporative cooler 113 to become low-temperature dehumidified air. It can be supplied into the room (SA) through the ventilation damper 116, and at this time, clean air can be supplied by removing foreign substances such as impurities through the filter 117 installed in the ventilation damper 116, and the fourth flow path ( The evaporative condenser 114 disposed in 110b) operates and drives the refrigerant cycle R1 together with the compressor 118 and the indoor unit 200 .

According to an embodiment of the present invention, some of the air introduced through the first flow path 110 is branched into the third flow path 110a and discharged to the outside (EA) through the wet channel of the evaporative cooler 113, The other part may be branched into the fourth flow path 110b and discharged (EA) to the outside through the evaporative condenser 114, or according to another embodiment of the present invention, the air supplied (OA) from the outside is evaporated. Some air that is discharged (EA) to the outdoors through the wet channel of the cooler 113 and is supplied (OA) from the outdoors or branched from the first flow path 110 is discharged to the outdoors through the evaporative condenser 114 (EA) can be

Thereafter, the RA ventilation damper 124 is opened to circulate the room, and the air required for regeneration is returned from the room (RA) and supplied to the second flow path 120, and the OA ventilation damper 123 is opened and supplied from the outside ( The air received OA) may be mixed with the air received RA from the room and supplied to the second flow path 120 together. The air supplied to the second flow path 120 passes through the heating unit 121 and is supplied to the dehumidifying rotor 130 in a heated state, thereby removing moisture contained in the second region 132 of the dehumidifying rotor 130 . It is evaporated, and the drying rate of the dehumidifying rotor 130 can be increased, so that the humid and high-temperature air can be discharged (EA) to the outside by the regeneration fan 122 .

That is, according to an embodiment of the present invention, the second flow path 120 is connected to the regeneration flow path of the dehumidification rotor 130 so that the air recovered from the indoor (RA) and the air supplied from the outside (OA) are transferred to the dehumidification rotor 130 . ) can be discharged to the outside (EA).

Alternatively, according to another embodiment of the present invention, the second flow path 120 is connected to the wet channel of the evaporative cooler 113 to convert the air recovered from the indoor (RA) or the air supplied from the outdoors (OA) to the evaporative cooler ( 113) may be discharged to the outside (EA) through the wet channel. In another embodiment of the present invention, one end of the second flow path 120 and the third flow path 110a may be connected or integrated in the middle.

At this time, when the outdoor unit 100 is driven, dehumidified and cooled air is provided to the room through the SA damper or the indoor unit 200 , and a cooling method using the refrigerant of the indoor unit 200 may be performed concurrently.

On the other hand, when the ventilation dehumidification cooling system according to an embodiment of the present invention performs the cooling mode as shown in FIG. 2 , the control module closes the ventilation damper 116 to block the inflow of air into the room. The dehumidification rotor 130, the dehumidification fan 112, the evaporative cooler 113, and the evaporative condenser 114 operate, and the OA ventilation damper 123 so that only outdoor air is supplied to the second flow path 120. ) is open and the RA ventilation damper 124 is closed, and the heating unit 121 and the regeneration fan 122 can be operated.

(115a) and the condensing fan (115b) can be operated.

As shown in FIG. 2 , when a separate ventilation mode is not driven, the ventilation damper 116 is closed to prevent air (OA), etc. introduced from the outside from flowing into the room (SA), and through this, Air returned to the outdoors (RA) is also not generated.

And, before passing through the evaporative condenser 114, the air (OA) supplied from the outdoors is passed through the dehumidifying rotor 130 and the dehumidifying fan 112 to dehumidify, and passes through the dry channel of the evaporative cooler 113 . By cooling it, the low-humidity air flows into the evaporative condenser 114 to increase the evaporation efficiency, and in addition, water is sprayed by the second water injection module to maximize the latent heat of evaporation to effectively reduce the condenser temperature. And, it is possible to maximize the cooling efficiency of the evaporative condenser (114).

Compared to the COP of the group, the COP according to an embodiment of the present invention reaches 1.5 times to 1.8 times, so that the cooling efficiency can be maximized.

Air (OA) introduced from the outdoors passes through the heating unit 121 and the dehumidifying rotor 130 through the second flow path 120 to evaporate moisture contained in the second region 132 of the dehumidifying rotor 130 and , it is possible to increase the drying rate of the dehumidifying rotor 130 , so that the humid and heat-exchanged air may be discharged (EA) to the outdoors by the regeneration fan 122 . At this time, since there is no air supplied to the room, the air recovered (RA) after indoor circulation is not supplied to the second flow path 120 .

In addition, the air used for heat exchange of the evaporative cooler 113 passes through the third flow path 110a, and the air used for heat exchange with the evaporative condenser 114 goes out through the fourth flow path 110b. The extraction fan 115a and the condensing fan 115b may be continuously driven to discharge (EA).

That is, according to an embodiment of the present invention, part of the air introduced through the first flow path 110 is branched into the third flow path 110a and discharged to the outside through the wet channel of the evaporative cooler 113 (EA). and the other part may be branched into the fourth flow path 110b and discharged (EA) to the outdoors through the evaporative condenser 114 .

In addition, when the amount of dehumidification is insufficient, the indoor unit 200 is operated to perform additional dehumidification to provide dehumidified air through the indoor flow path A10 shown in FIG. It is performed by switching to the ventilation dehumidification cooling mode to operate the condenser 114 together, and when the amount of dehumidification is satisfied, it may be switched back to the ventilation and dehumidification mode to be performed.

That is, the ventilation dehumidification mode according to an embodiment of the present invention, as shown in FIG. 3, is almost the same as the air flow in the ventilation dehumidification cooling mode of FIG. Since there is no need, the evaporative condenser 114 and the second water injection module can be stopped without operating. Since the evaporative condenser 114 is not driven, the second water supply module as well as the extraction EA damper installed in the fourth flow path 110b is closed, and the condensing fan 115b does not operate, and the evaporative condenser 114 is closed. The connected compressor 118 also does not operate.

However, when there is a lot of external moisture, such as in summer or the rainy season, when the amount of dehumidification is insufficient by driving the outdoor unit 100, the dehumidification amount can be supplemented by operating the air conditioner of the indoor unit 200. For this, the evaporative condenser 114 and By driving the compressor 118 , the refrigerant cycle R1 of the indoor unit 200 may be operated.

Although FIG. 3 shows that the refrigerant cycle R1 is being operated, this is a case in which the indoor unit 200 is driven to drive the evaporative condenser 114 and the compressor 118 together. If they are not driven together, the refrigerant cycle R1 is also not activated.

In addition, since there is no air OA to be introduced from the outdoors through the second flow path 120, the regeneration OA damper installed in the second flow path 120 to introduce air from the outdoors is closed, and the air recovered after indoor circulation ( The regeneration fan 122 may operate so that only RA) passes through the heating unit 121 and the dehumidifying rotor 130 for regeneration.

If, as in another embodiment of the present invention, the recovered air RA after indoor circulation is discharged to the outside through the third flow path 110a, the heating unit 121 and the regeneration fan 122 are also stopped. can

Ventilation mode can be further performed. The control module may additionally open only the OA ventilation damper 123 when performing the dehumidification ventilation mode, and control the rest in the same manner as in the ventilation and dehumidification mode. Accordingly, the ventilation and dehumidification mode and the dehumidification ventilation mode do not perform cooling, but weak cooling may be incidentally performed through the evaporative cooler in operation, and thus may be included in the cooling small mode.

A configuration that heats air like the unit 121 does not operate, and only total heat exchange can be performed. Therefore, after passing through the dehumidifying rotor 130 , the air does not absorb heat or discharge heat until it is supplied into the room (SA). At this time, the operation of the first water injection module and the second water injection module in the evaporative condenser 114 and the evaporative cooler 113 are also stopped, so that a separate latent heat exchange does not occur.

In addition, as the evaporative cooler 113 and the evaporative condenser 114 do not drive, the condenser fan 115b and the extraction fan 115a do not drive, either, and the extraction EA damper and the second extraction EA installed in the fourth flow path 110b are not driven. The extraction EA damper installed in the third flow passage 110a and the regeneration OA damper installed in the second flow passage 120 are also closed, so that there is no air flow.

As shown in FIG. 5 , the ventilation dehumidification cooling system according to another embodiment of the present invention may perform a dehumidification mode. The control module closes the ventilation damper 116 to block the inflow of air into the room when the dehumidification mode is performed, and the dehumidification rotor 130, the dehumidification fan 112 and the evaporative cooler 113 operate The OA ventilation damper 123 is open and the RA ventilation damper 124 is closed so that only outdoor air is supplied to the second flow path 120 , and the heating unit 121 and the regeneration fan 122 operate can do it

The extraction fan 115a and the condensing fan 115b may be operated. At this time, the ventilation damper 116 is closed so that the air introduced into the first flow path 110 passes through the evaporative condenser 114 and the evaporative condenser 114 is not driven.

It can be discharged immediately.

Alternatively, separate diffusers SA and RA may be installed to separate the air provided from the outdoor unit 100 and the air provided from the indoor unit 200 and supply them to the room.

It is possible to provide outdoor air that is directly dehumidified at low temperature through the indoor unit 200 and ventilated through the filter 117, so that cooling, dehumidification, and ventilation can all be performed with one indoor unit 200, and a separate device for each mode It does not need to be installed indoors, saving indoor space and improving user experience.
