In addition, although not shown in FIG. 1 , the air conditioner 1 may include a discharge unit for receiving the air treated by the air conditioner 1 and discharging the introduced air to the outside.

The ventilation device 10 is a device for introducing outdoor air into the room. An inlet (not shown) to be connected to the ventilation device 10 may be included in the air conditioning unit 1 . One side of the ventilation device 10 may be connected to an inlet of the air conditioner 1 , and the other side may be connected to a ventilation pipe (not shown).

Accordingly, the ventilation device 10 may guide the external air introduced from the ventilation pipe toward the air conditioner 1 . A detailed description of the configuration of the ventilation device 10 will be described later with reference to FIGS. 4 to 5 .

The ventilation pipe may be a passage that is connected to the outdoors and introduces outdoor air. The ventilation pipe may be directly connected to the outdoors, but it may be connected to an ERV (Energy Recovery Ventilation) system of the total heat exchanger 20 so that ERV-treated outdoor air may be introduced. A detailed description of an operation in which outdoor air is transferred to the ventilation device 10 and the air conditioner 1 through the total heat exchanger 20 will be described later with reference to FIGS. 2 to 3 .

The ventilation device 10 may be detachably coupled to the air conditioner 1 . For example, the fan assembly 100 and the duct 200 of the ventilation device 10 may be respectively disposed inside and outside the inlet of the air conditioner 1 to be detachably coupled to the air conditioner 1 . . A detailed description of the fan assembly 100 and the duct 200, which are components of the ventilation device 10, will be described later with reference to FIGS. 2 to 3 .

The fan assembly 100 of the ventilation device 10 may be disposed inside the inlet of the air conditioner 1 to be detachably coupled from the air conditioner 1 . For example, the fan assembly 100 may be screwed into the body of the air conditioner 1 .

In this case, a position at which the fan assembly 100 is fastened to the air conditioner 1 may be formed to be close to the external filter of the air conditioner 1 . Accordingly, when service for the fan assembly 100 is required, the fan assembly 100 can be detached from the air conditioner 1 after only the external filter is removed without disassembling the entire air conditioner 1 . .

Meanwhile, the duct 200 of the ventilation device 10 may be disposed outside the inlet of the air conditioner 1 to be detachably coupled from the air conditioner 1 . For example, in the duct 200 , the discharge member 220 may be disposed on one side adjacent to the air conditioner 1 , and the discharge member 220 is inserted into the inlet of the air conditioner 1 to generate friction or It may be coupled to the air conditioner 1 through fastening with screws.

In this case, the fan assembly 100 may be detachably mounted to the duct 200 on one side of the duct 200 adjacent to the air conditioner 1 . A detailed description of the configuration of the duct 200 will be described later with reference to FIGS. 4 to 6 .

FIG. 2 is a diagram for explaining an operation in which outdoor air is supplied to the air conditioner 1 through the total heat exchanger 20 and the ventilation device 10, and indoor air is exhausted to the outside through the total heat exchanger 20 .

The total heat exchanger 20 absorbs energy from the polluted air discharged from the room to the outside and transfers energy to the fresh air flowing into the room from the outside, thereby maintaining the indoor temperature and humidity and reducing energy used for indoor air conditioning. It is a device that can

For example, when the external temperature and humidity are high, such as in summer, the total heat exchanger 20 reduces heat and moisture by transferring heat and moisture contained in the outdoor air flowing in from the outside to the air exhausted from the room to the outside. Air is supplied to the room, and when the outside temperature and humidity are low, such as in winter, heat and moisture from the air discharged from the room to the outside can be recovered and transferred to the outside air, and then air can be supplied to the room.

The ventilation pipe of the ventilation device 10 may be connected to the total heat exchanger 20 , and may receive external air in which energy has been exchanged from the total heat exchanger 20 and transmit it to the air conditioner 1 . For example, the ventilation pipe of the ventilation device 10 may be fluidly connected to the air inlet 24 of the total heat exchanger 20 (refer to FIG. 3 ). Accordingly, energy used for indoor air conditioning may be reduced compared to a case in which the ventilation pipe is directly connected to the outdoors.

3 is a view for explaining a total heat exchanger 20 according to an embodiment of the present disclosure. For convenience of explanation of the internal structure of the total heat exchanger 20 , FIG. 3 is illustrated except for one side of the housing forming the exterior of the total heat exchanger 20 .

The total heat exchanger 20 can receive fresh air from the outdoors through the outdoor air inlet 21 and deliver the energy exchanged air through the air inlet 24 to the ventilation device 10 and the air conditioner 1, It is possible to receive polluted air from the room through the inlet 23 and exhaust the energy-exchanged air to the outside through the exhaust port 22 .

The air flowing into the total heat exchanger 20 from the outside and the air flowing into the total heat exchanger 20 from the inside pass through the heat transfer element 25 at the same time to exchange energy. For example, the heat transfer element 25 may have a stacked structure in which layers forming a flow path for air flowing into the room from the outside and layers forming a flow path for air discharged from the room to the outside are alternately arranged. Accordingly, energy can be exchanged without mixing the air introduced into the room through the heat transfer element 25 and the air discharged to the outside.

The filters 26 and 27 are disposed adjacent to the outdoor air inlet 21 and the indoor air inlet 23, respectively, and may primarily filter contaminants included in the air flowing into the total heat exchanger 20. In this case, the filters 26 and 27 may be a pre-filter or a HEPA filter, and a plurality of filters may be applied simultaneously.

Meanwhile, the duct 200 may include an air filter therein. Accordingly, foreign substances present in the outdoor air transmitted to the air conditioner 1 through the duct 200 may be filtered.

The duct 200 may include a first duct member 210 and a second duct member 230 that are separable from each other. In this case, one side of the first duct member 210 may be connected to the air conditioner 1 , and one end of the second duct member 230 may be connected to the ventilation pipe.

However, the configuration of the duct 200 is not limited thereto, and the air conditioner 1 and the ventilation pipe may be connected in a single configuration.

One side of the second duct member 230 may be connected to one side of the first duct member 210 in a shape corresponding to one side of the first duct member 210 , and the other side of the second duct member 230 is a ventilation pipe It can be connected to the ventilation pipe in a shape corresponding to the cross-section of one side of the.

For example, when the cross-section of the ventilation pipe is circular, one end at which the second duct member 230 is connected to the ventilation pipe may be formed in a circular shape.

In this case, the housing 120 may have a shape corresponding to the shape of one side of the duct 200 to which the housing 120 is mounted. For example, when the discharge member 220 of the duct 200 has a rectangular shape, the housing 120 may have a corresponding rectangular shape.

Although not shown in FIG. 5 , the fan assembly 100 may include a motor for driving the fan 110 and a wiring member that provides driving power to the fan 110 . The fan 110 may be driven by receiving driving power from the outside through a wiring member. In this case, the wiring member may provide driving power for driving the motor to the motor, and may provide a control signal for controlling the operation of the damper to the damper.

Meanwhile, although it has been described above that the fan assembly 100 includes a wiring member, the wiring member may be configured to be separable from the fan assembly 100 . For example, a terminal for connecting to a wire may be positioned on one side of the fan assembly 100 , and a cable may be connected to the terminal to receive various driving signals and driving power from the air conditioner 1 .
