The outdoor environment measuring unit measures the outdoor environment and transmits the environmental information to the control unit 130. The season determining unit calculates the date or transmits the environmental information of the outdoor air to the control unit 130 by classifying the seasons by a snack, a winter season, a winter season, a cold season, a cold season,

The outdoor environment measurement unit and the season determination unit may be provided in the air supply apparatus 100 itself to receive environment information of the outdoor air from the outdoor air measurement unit and may receive environmental information of the outdoor air from a server of an external company (Not shown).

The air supply system 1 according to another embodiment of the present invention will be described with reference to Fig.

The air supply system 1 shown in FIG. 4 includes a first damper unit 200-1 opened and closed to supply outdoor air supplied through the air supply duct 41 to the kitchen 20, And a second damper unit 200-2 that is opened and closed to supply outdoor air supplied through at least one of the plurality of indoor spaces 21 to 25 to the indoor space of at least one of the plurality of indoor spaces 21 to 25 except for the kitchen 20 .

A point where the first supply duct 41-1 and the second supply duct 42 intersect with the indoor supply port 111 intersects the third intersection 41-1c and the first supply duct 41- 1 and the third supply duct 43 intersect is the fourth intersection 41-1d.

In this case, the first air supply duct 41-1 includes a first duct portion 41-1a connecting the third intersection 41-1c from the indoor supply port 111 to the third intersection point 41-1a, And the second duct portion 41-1b constituting the first supply duct 41-1 after the second duct portion 41-1c.

The first damper unit 200-1 is provided in the second air supply duct 42 to allow air to flow or cut through the second air supply duct 42. [

The second damper unit 200-2 is provided at the third intersection 41-1c and the fourth intersection 41-1d.

When the outdoor air is supplied to the kitchen 20, the first damper unit 200-1 is opened and the second damper unit 200-2 is shut off, the outdoor air is supplied only to the kitchen 20 , It is possible to increase the supply air volume to prevent the contaminated air from diffusing and to maximize the exhaust efficiency by the exhaust fan 30. [

The first damper unit 200-1 is shut off and the second damper unit 200-2 is opened so that the air supplied from the air supply apparatus 100 is supplied to the kitchen 20 And supplied to the remaining indoor spaces (21 to 25).

In addition, both the first damper unit 200-1 and the second damper unit 200-2 may be opened to supply air to all the indoor spaces 20-25.

The first damper unit 200-1 and the second damper unit 200-2 may be controlled by a control signal transmitted from the control unit 130 of the air supply device 100, And the control signal may be transmitted from the controller.

4, it is also possible to configure the air supply duct to be connected to a position nearest to the air supply device 100 than the other indoor spaces 21 to 25 in the embodiment shown in FIG. have. Accordingly, the air supplied from the air supply device 100 is short in the route to the kitchen 20, so that the static pressure loss can be minimized and the air supply efficiency can be improved.

As described above, it is most preferable to construct the air supply duct so that the path for air supply to the kitchen 20 is as short as possible. However, the air supply duct can be modified into other forms. For example, two first duct portions are connected to the air supply device 100 instead of one first duct portion 41-1a, and one of the two first duct portions is connected to the kitchen 20 And the other one of the first duct portions may be connected to the second duct portion 41b so as to be connected to the other indoor spaces 21 to 25 except the kitchen 20 have.

The first duct portions 41a and 41-1a shown in FIGS. 1 and 4 include a second air supply duct 42 connected to the kitchen 20 and a third air supply duct 43 connected to the living room 21 The first duct portions 41a and 41-1a are formed so that the second duct portions 41b and 41-1b and the other air supply ducts 43 to 47 ) In the direction of the arrows.

FIG. 5 is a diagram illustrating an air supply method according to an embodiment of the present invention in which a bathroom mode is activated during operation in a kitchen mode. The air supply method in the air supply system shown in Fig. 1 will be described. In the air supply method in the air supply system shown in Fig. 2, only the control in the damper units 200-1 and 200-2 is different. The description will be omitted.

In step S101, the exhaust fan 30 of the kitchen 20 is operated while the user is cooking.

In step S102, the opening and closing of the damper section is set. When the exhaust fan 30 is operated, the control unit (not shown) of the air supply device 100 controls the flow of outdoor air supplied from the air supply device 100 to flow from the first duct part 41a to the second duct part 41b 130 make the damper unit 200 closed. If the damper unit 200 is already in the closed state, step S102 may be omitted. In this case, the outdoor air supplied from the air supply device 100 is not completely blocked from flowing from the first duct part 41a to the second duct part 41b, but the outdoor air is supplied with a supply amount smaller than the maximum possible supply amount The opening degree of the damper unit 200 may be adjusted so that the damper unit 200 is partially opened.

The air supply device 100 is operated in step S103 to operate in a kitchen mode in which outdoor air is supplied to the kitchen 20 through the first duct part 41a and the second air supply duct 42. [ Accordingly, it is possible to prevent the polluted air in the kitchen 20 from diffusing into another indoor space, to prevent the negative pressure from being formed deeply in the space of the kitchen 20, so that the polluted air is smoothly exhausted, , It is possible to prevent noise and vibration from occurring.

When the damper unit 200 is operated in the kitchen mode while closing the damper unit 200 or setting the opening degree of the damper unit 200 to be supplied at a supply amount smaller than the maximum allowable supply amount, So that the exhaust efficiency of the kitchen 20 can be further improved.

In step S104, it is determined whether the bathroom mode is activated. If the user uses the baths 26 and 27 to operate the exhaust fans 31 and 32, the process proceeds to step S105, and if not, the process proceeds to step S107.

The opening and closing of the damper unit 200 is reset in step S105. That is, the closed damper unit 200 is opened so that the outdoor air supplied from the air supply device 100 is simultaneously supplied to the other indoor spaces 21 to 25 including the kitchen 20.

If it is determined in step S102 that the damper unit 200 is opened to be supplied with the supply amount smaller than the maximum possible supply amount, the damper unit 200 may be fully opened to supply the maximum possible supply amount.

In step S106, air is simultaneously supplied to the kitchen 20 and the baths 26 and 27. When the exhaust fans 31 and 32 are operated, the internal spaces of the baths 26 and 27 are in a sound pressure state. At the same time, when outdoor air is supplied to the living room 21 or the inside space 22, the air in the living room 21 or the inside space 22 is supplied to the baths 26 and 27 through the connecting ducts 51 and 61. Alternatively, the connection damper 52, 62 may be opened by a pressure difference or by a control signal of the control unit 130 of the air supply device 100 so that the air in the living room 21 or the interior space 22 is supplied to the bathroom 26, 27). As a result, the polluted air in the bathrooms 26 and 27 is exhausted smoothly, so that the exhaust efficiency can be improved and noise and vibration can be prevented. In addition, since air is supplied using the air in the living room 21 or the inner space 22, which is an indoor space, the outdoor air of the poor environment flows directly into the baths 26 and 27, Can be prevented.

In the above description, when air is supplied to the baths 26 and 27, outdoor air is supplied to the living room 21 or the inside space 22, and air in the living room 21 or the inside space 22 is supplied to the baths 26 and 27 The air in the living room 21 or the room 22 can be supplied to the rooms 26 and 26 while the outdoor air is prevented from being supplied to the living room 21 or the room 22 on the basis of the environmental information of the outdoor air, 27 as shown in FIG.

That is, when at least one of temperature, humidity, or dust concentration of the outdoor air, which is the received environmental information, is outside the set range and it is determined that the environment of the outdoor air is poor It is possible to prevent the outdoor air from being supplied to the living room 21 or the inner room 22 by closing the damper unit 200 to thereby create a pleasant indoor environment and to prevent the user from feeling uncomfortable.

If the received environment information is within the set range, it is determined that the outdoor air environment is not poor, and the outdoor air is supplied to the living room 21 or the inside room 22 by opening the damper unit 200, The outdoor air supplied to the indoor space 21 or the outdoor space 22 can be supplied to the bathrooms 26 and 27. [

In the above description, the case where the kitchen mode and the bathroom mode are operated at the same time has been described. The air in the living room 21 or the inside space 22 communicating with the kitchen 20 is supplied to the baths 26 and 27 so that the air in the kitchen 20 is moved to the living room 21 or the inside room 22, Even if outdoor air is supplied to the kitchen 20, a sufficient positive pressure is not formed in the kitchen 20 and the living room 21 or the inside room 22 adjacent thereto. Therefore, the exhaust efficiency of the kitchen 20 is lowered and the air contaminated by the living room 21 or the inside room 22 can be diffused. In addition, contaminated air in the kitchen 20 can be introduced into the bathrooms 26, 27 through the living room 21 or the inside room 22.

An air supply method for solving such a problem will be described with reference to Fig.

FIG. 6 is a method of supplying air according to another embodiment of the present invention.

In step S201, the user operates the exhaust fan 30 while cooking and operates in the kitchen mode.

The exhaust fans 31 and 32 of the bathrooms 26 and 27 are activated while the user uses the bathroom while operating in the kitchen mode in step S202.

When the exhaust fans 31 and 32 of the bathrooms 26 and 27 are activated in step S203, the connection dampers 52 and 62 are shut off to let the air in the living room 21 or the interior space 22 pass to the bathrooms 26 and 27 It blocks the supply. When the supply of air to the bathrooms 26 and 27 is blocked, sufficient supply of air to the kitchens 20 can be performed to form a positive pressure in the kitchen 20 and the living room 21 or the living room 22 communicating therewith, Diffusion can be prevented, and the exhaust efficiency of the kitchen 20 can be improved. Also, inflow of contaminated air from the kitchen can be prevented to the bathrooms 26,

In step S204, it is determined whether or not the setting condition is satisfied. The setting condition may be a case where the degree of contamination of the kitchen 20 sensed by the first indoor environment sensing unit 310 is lowered to a predetermined level or less. Further, when supply of outdoor air to the kitchen 20 is performed for a predetermined period of time while the air supply to the baths 26 and 27 is cut off, it can be determined that sufficient positive pressure is formed, When the predetermined time has elapsed after the exhaust fans 31 and 32 of the engine 10 are operated.

If the setting conditions are satisfied in step S205, the connection dampers 52 and 62 are opened to allow the air in the living room 21 or the interior space 22 to be supplied to the bathrooms 26 and 27.

It is determined in step S206 whether the operation of the exhaust fans 30, 31, 32 is stopped. When the operation of the exhaust fans 30, 31, 32 is stopped as a result of the determination, the kitchen mode or the bathroom mode is terminated.

According to such an air supply method, the exhaust efficiency of the kitchen 20 can be improved, and contaminated air in the kitchen 20 can be prevented from being supplied to the baths 26 and 27.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And this also belongs to the present invention.
