Detailed Description
Hereinafter, an air supply system and an air supply method according to the present invention will be described in detail with reference to the accompanying drawings.
An air supply system according to an embodiment of the present invention is explained with reference to fig. 1.
The utility model discloses an air supply system 1 is equipped with to supply at least one interior space in a plurality of interior space 20 ~ 27 with outdoor air.
For example, the plurality of indoor spaces 20 to 27 may include a kitchen 20, a living room 21, a bedroom 22, a room 123, a changing room 24, and a room 225, and may further include a bathroom 126 adjacent to the living room 21 and a bathroom 227 adjacent to the bedroom 22.
The air supply system 1 may be provided with an air supply device 100 for supplying outdoor air to the plurality of indoor spaces 20 to 27.
The gas supply device 100 is provided with: an indoor supply port 111 for supplying air to the plurality of indoor spaces 20 to 25; an indoor air inlet 112 for allowing air in the plurality of indoor spaces 20 to 25 to flow into the air supply device 100; an outdoor air inflow port 113 through which outdoor air flows into the air supply device 100; and an outdoor discharge port 114 for discharging air to the outside.
The gas supply device 100 may operate in one or more of the following modes: an air supply dedicated mode for supplying outdoor air to a plurality of indoor spaces 20-25; a ventilation mode for discharging indoor air to the outside of the room and supplying outdoor air to the inside of the room; an air cleaning mode in which a filter in the air supply device 100 filters foreign substances contained in the air in the plurality of indoor spaces 20 to 25 and supplies the filtered foreign substances to the indoor spaces 20 to 25 again; a cooling mode for cooling the indoor air; and a heating mode for heating the indoor air. In this case, since the supply of outdoor air into the room is also performed in the ventilation mode, the air supply dedicated mode and the ventilation mode will be collectively referred to as an air supply mode hereinafter. The state where the outdoor air is not supplied to the indoor spaces 20 to 25 is referred to as an air supply blocking mode.
Air supply ducts 41 to 47 for supplying air to the respective indoor spaces 20 to 25 are connected between the indoor supply port 111 of the air supply device 100 and the plurality of indoor spaces 20 to 25.
And, the air supply system 1 includes an air supply part 50, 60 for supplying air of the second indoor space 21, 22 to the first indoor space 26, 27 when discharging contaminated air of the first indoor space 26, 27 to the outside.
also, the air supply system 1 may further include exhaust fans 31, 32 for discharging contaminated air of the first indoor spaces 26, 27 to the outside.
The first indoor spaces 26, 27 can include more than one of a bathroom 126 adjacent to living room 21 and a bathroom 227 adjacent to bedroom 22. The exhaust fans 31, 32 may include an exhaust fan 31 for exhausting contaminated air of the bathroom 126 to the outside and an exhaust fan 32 for exhausting contaminated air of the bathroom 227 to the outside.
And, an exhaust fan 30 for exhausting contaminated air generated while the kitchen 20 is cooking to the outside may be provided.
Also, the gas supply part 50, 60 may include: a first air supply part 50 for supplying air of the living room 21 to the bathroom 126 when the exhaust fan 31 of the bathroom 126 is operated; a second air supply portion 60 for supplying air of the bedroom 22 to the bathroom 227 when the exhaust fan 32 of the bathroom 227 is operated.
The first air supply part 50 may include a connection duct 51 connecting between the space of the bathroom 126 and the space of the living room 21.
The connection pipe 51 can connect a connection port provided in the ceiling of the bathroom 126 and a connection port provided in the ceiling of the living room 21. The bathroom 126 communicates with the space of the living room 21 through the connecting duct 51. Therefore, if a negative pressure is formed in bathroom 126 due to the operation of exhaust fan 31, the air of living room 21 can be naturally supplied to bathroom 126 through connecting duct 51.
Also, the first air supply part 50 may further include: and a connecting damper 52 provided to the connecting duct 51 to communicate or block the space of the bathroom 126 with or from the space of the living room 21.
The connection damper 52 may be configured to be opened and closed by a pressure difference generated between the bathroom 126 and the living room 21 according to whether the exhaust fan 31 is operated or not. That is, the connecting damper 52 may include: a damper member (not shown) for partitioning the space inside the connection duct 51 into spaces communicating with the bathroom 126 side and the living room 21 side, respectively; and an elastic member (not shown) elastically supporting the damper member. When the exhaust fan 31 is operated, a negative pressure is formed in the space of the bathroom 126, and therefore the air pressure in the living room 21 is higher than the air pressure in the bathroom 126. Accordingly, the damper member is switched from the closed state to the open state against the elastic force of the elastic member due to the formation of the negative pressure, and the air of living room 21 is supplied to bathroom 126. Thereafter, when the exhaust fan 31 stops operating, the air pressure in the bathroom 126 is in a state of equilibrium with the air pressure in the living room 21, and therefore the damper member is closed by the elastic force of the elastic member, and is in a blocking state. In this case, the connecting damper 52 can adjust the degree of opening and closing according to the degree of the pressure difference.
The connection damper 52 may be opened and closed by a control signal. It may be configured to transmit a control signal applied to the connection damper 52 from the control unit 130 (fig. 2) of the air supply apparatus 100, or may be configured to transmit a control signal from an independent switch or controller. In this case, the opening degree of the connecting damper 52 is adjusted, so that the amount of air supplied to the first indoor spaces 26 and 27 can be adjusted.
The second gas supply part 60 may include the same configurations 61, 62 as the first gas supply part 50.
Since smells or moisture is generated in the first indoor spaces 26, 27 when the user uses the bathroom, the exhaust fans 31, 32 are operated to discharge the smells and moisture to the outside.
As described above, if the exhaust fans 31 and 32 are operated to discharge contaminated air including odor and moisture to the outside, negative pressure is formed inside the first indoor spaces 26 and 27, and thus the exhaust cannot be smoothly performed, and if the exhaust fans 31 and 32 are continuously operated in such a state, noise and vibration are gradually increased.
In order to prevent such a problem, the air in the second indoor spaces 21 and 22 is supplied to the first indoor spaces 26 and 27 through the air supply parts 50 and 60, so that the contaminated air in the first indoor spaces 26 and 27 can be rapidly discharged to the outside, the negative pressure is prevented from being formed in the first indoor spaces 26 and 27, and the noise and vibration generated by the operation of the exhaust fans 31 and 32 can be minimized.
If the outdoor air supplied from the air supply device 100 is directly supplied to the first indoor spaces 26, 27, the outdoor air due to the severe environment may cause discomfort to the user.
In this case, whether or not the environment is a severe environment can be judged from at least one of the temperature, humidity, and dust concentration of the outdoor air.
That is, if outdoor air is directly supplied from the air supply device 100 to the first indoor spaces 26 and 27 in the case where the outdoor temperature is extremely high, such as in a hot summer season, or in the case where the outdoor temperature is extremely low, such as in a winter season, hot outdoor air in summer or cold outdoor air in winter flows into the first indoor spaces 26 and 27 as they are, and therefore, the user may feel uncomfortable when using the bathroom. Also, in the case where the humidity of the outdoor air is high such as in rainy season, if the outdoor air with high humidity flows into the first indoor spaces 26 and 27 and then spreads to the second indoor spaces 21 and 22, an uncomfortable indoor environment may be caused. Also, in the case where the dust concentration of the outdoor air is high, the dust concentration of the first and second indoor spaces 26 and 27 and 21 and 22 may be increased due to inflow of the outdoor air containing the high concentration of dust. In addition, in the case where cold outdoor air flows in winter, there is a possibility that moisture remaining on the floor of the bathrooms 26 and 27 freezes.
Therefore, when the air supply units 50 and 60 are provided as described above, the air in the second indoor spaces 21 and 22 is supplied to the first indoor spaces 26 and 27 without allowing the outdoor air to flow into the first indoor spaces 26 and 27 as it is when the outdoor environment is bad, so that it is possible to smoothly discharge the contaminated air in the first indoor spaces 26 and 27 while preventing the outdoor air in the bad environment from flowing into the room and causing discomfort to the user.
In this case, negative pressure may also be formed in the second indoor spaces 21, 22, however, since the second indoor spaces 21, 22, such as the living room 21 or the bedroom 22, are configured as a space larger than the first indoor spaces 26, 27, the degree of negative pressure formation is weak. The above-described weak negative pressure mode can be released by supplementing the second indoor spaces 21 and 22 with outdoor air through the window and door slits or supplementing air of the other indoor spaces 20, 23, 24, and 25 communicating with the second indoor spaces 21 and 22 with air.
If the outdoor environment is not poor, the outdoor air may be supplied from the air supply device 100 to the second indoor spaces 21 and 22. That is, the outdoor air supplied from the air supply device 100 may be flowed into the second indoor spaces 21 and 22 through the air supply ducts 41, 43 and 44, and the air of the second indoor spaces 21 and 22 may be supplied to the first indoor spaces 26 and 27 through the air supply parts 50 and 60. In this case, even if the state of the outdoor air is somewhat bad, it is mixed with the air of the second indoor spaces 21, 22 that form a comfortable state, and even if the air thus mixed is supplied to the first indoor spaces 26, 27, it does not cause discomfort to the user.
The configuration may be such that, when the outdoor air is supplied to the second indoor spaces 21 and 22, the state of the outdoor air is first determined, and when the state of the outdoor air satisfies a set criterion, the supply of the outdoor air to the second indoor spaces 21 and 22 is blocked, otherwise. In this case, the state of the outdoor air may be determined from the temperature, humidity, and dust concentration of the outdoor air, for example.
In addition, when cooking in the kitchen 20, the exhaust fan 30 may be operated to discharge contaminated air of the kitchen 20 to the outside. In this case, since the outdoor air is supplied from the air supply device 100 to the kitchen 20 through the air supply ducts 41 and 42, contaminated air in the space of the kitchen 20 can be prevented from being diffused to other adjacent indoor spaces, and severe negative pressure can be prevented from being formed in the space of the kitchen 20, and thus the air can be smoothly discharged, so that the air discharge efficiency can be improved, and noise and vibration can be prevented from being generated.
The air supply system 1 may further include: a first damper 71 opened and closed to supply the outdoor air supplied through the air supply duct 41 to the kitchen 20; and a second damper 72 opened and closed to supply the outdoor air supplied through the air supply duct 41 to at least one of the plurality of indoor spaces 21 to 25 except the kitchen 20.
If the first damper 71 is opened and the second damper 72 is blocked in the case of supplying the outdoor air to the kitchen 20, the outdoor air is supplied only to the kitchen 20, and thus the supply air volume can be increased, so that the contaminated air can be prevented from being diffused, and the exhaust efficiency of the exhaust fan 30 can be maximized.
Except in the case of cooking in the kitchen 20, the first damper 71 is blocked and the second damper 72 is opened, so that the air supplied from the air supply device 100 is supplied to the remaining indoor spaces 21-25 except for the kitchen 20.
The first damper 71 and the second damper 72 may be controlled by a control signal transmitted from the control unit 130 (fig. 2) of the air supply apparatus 100, or may be controlled by a control signal transmitted from an independent switch or controller.
The first damper 71 and the second damper 72 may be configured to be fully opened or fully closed, but at least one of the first damper 71 and the second damper 72 may be configured to be adjustable in opening degree. For example, the amount of outdoor air supplied to the kitchen 20 may be adjusted by adjusting the opening degree of the first damper 71, and the control unit 130 may be configured to adjust the opening degree such that the opening degree of the second damper 72 is smaller than that in the fully opened state in the state where the first damper 71 is fully opened, thereby supplying an air supply amount smaller than the maximum air supply amount to the remaining indoor spaces 21 to 25 except the kitchen 20. Here, the maximum air-suppliable amount indicates an air-supply amount in a case where the second damper 72 is completely opened.
Further, the control unit 130 may be configured to control the outdoor air amount (a, the outdoor air amount supplied by the air supply device 100) supplied to all of the plurality of indoor spaces 20 to 25 to be equal to or larger than (a ≧ B) the outdoor air amount (B) supplied to the kitchen 20 when the outdoor air is supplied to the kitchen 20 among the plurality of indoor spaces 20 to 25. This means that all the outdoor air supplied through the air supply device 100 is supplied only to the kitchen 20, or a part of the outdoor air is supplied to the remaining indoor spaces 21-25 except the kitchen 20.
The control unit 130 may be configured to control the amount of outdoor air supplied to the kitchen 20 to be larger than the amount of outdoor air supplied to the remaining indoor spaces 21 to 25 except the kitchen 20 when the outdoor air is supplied to the kitchen 20 among the plurality of indoor spaces 20 to 25.
In addition, the following case is explained as an example in the above: the air supply device 100 is connected with one air supply duct 41 (first air supply duct), and includes a second air supply duct 42 connecting the first air supply duct 41 with the kitchen 20 and third to seventh air supply ducts 43 to 47 connecting between the remaining indoor spaces 21 to 25 except the kitchen 20 and the first air supply duct 41.
In this case, the kitchen 20 may be configured such that the air supply duct is connected to a position closest to the air supply device 100 than the other indoor spaces 21 to 25. If the galley 20 is connected to the position closest to the air supply device 100 as described above, the path of the air supplied from the air supply device 100 to the galley 20 is short, so that the static pressure loss can be minimized to improve the air supply efficiency.
Although it is most preferable to configure the path of the air supply to the kitchen 20 as short as possible as described above, the configuration of the air supply duct may be modified to another configuration. For example, instead of one first air supply duct 41, two first air supply ducts may be connected to the air supply device 100, one of which is connected to the second air supply duct 42 connected to the kitchen 20, and the remaining one of which is connected to the third to seventh air supply ducts 43 to 47 connected to the remaining indoor spaces 21 to 25 except for the kitchen 20.
Although the first air supply duct 41 shown in fig. 1 is configured to form the intersection C1 between the second air supply duct 42 connected to the kitchen 20 and the third air supply duct 43 connected to the living room 21, the first air supply duct 41 may be alternatively configured to be connected between intersections of the other air supply ducts 43 to 47. That is, the connection may be made between the intersection C2 and the intersection C3, between the intersection C3 and the intersection C4, and between the intersection C4 and the intersection C5.
Although the above description is made in the case where two dampers, i.e., the first damper 71 and the second damper 72, are provided, it may be made in the case where one damper is provided at the intersection C1 or the supply duct adjacent to the intersection C1. In this way, one damper may be provided as described above, and the outdoor air supplied through the first air supply duct 41 may be supplied to any one of the kitchen 20 and the remaining indoor spaces 21 to 25, or the opening degree of the damper may be adjusted to supply the outdoor air to both sides of the kitchen 20 and the remaining indoor spaces 21 to 25.
With reference to fig. 2, a configuration of the air supply system 1 according to an embodiment of the present invention will be described.
the gas supply device 100 may include: a control part 130 for controlling an air supply mode for supplying outdoor air to the indoor according to the operation information received from the exhaust fans 30, 31, 32; a communication unit 120 that performs communication with the exhaust fans 30, 31, and 32; an air supply blower 141 for supplying outdoor air to the indoor.
when the air supply device 100 is configured by an air conditioner such as an air conditioner, a cooling/heating facility, or a ventilator, functions of ventilation, air purification, dehumidification, humidification, cooling, and heating modes may be provided, and for this purpose, an exhaust blower 142 for discharging indoor air to the outside may be provided.
The air supply device 100 may include a heat exchange unit 150 that exchanges heat between indoor air discharged to the outside of the room and outdoor air introduced into the room in the ventilation mode. For example, the heat exchange portion 150 may include a desiccant rotor. Heat exchange is performed in the heat exchange unit 150, so that heat efficiency can be improved.
The gas supply apparatus 100 may include a heating unit 161 and a cooling unit 162. The heating unit 161 heats outdoor air supplied to the indoor spaces 20 to 25, thereby preventing cold outdoor air from flowing into the indoor space in winter. The cooling unit 162 cools outdoor air supplied to the indoor spaces 20 to 25, thereby preventing hot outdoor air in summer from flowing into the indoor space as it is.
The environmental information of the outdoor air is received to the control part 130 of the air supply device 100. The environmental information of the outdoor air may be a temperature, humidity, dust concentration, etc. of the outdoor air, and may be composed of one or more of the above-mentioned pieces of information. In order to receive the environment information of the outdoor air, an outdoor environment measuring part 171 for measuring the environment of the outdoor air or a season judging part 172 for judging the season may be provided. The outdoor environment measuring part 171 may include one or more of a temperature sensor for measuring an outdoor air temperature, a humidity sensor for measuring an outdoor air humidity, and a dust sensor for measuring an outdoor air dust concentration. The outdoor environment is measured by the outdoor environment measuring unit 171, and the environment information is transmitted to the control unit 130. The season determination unit 172 calculates a date or classifies seasons into season changes, winter seasons, summer seasons, severe cold periods, severe heat periods, and the like, and further transmits environmental information of outdoor air to the control unit 130.
The outdoor environment measuring unit 171 and the season determining unit 172 may be provided in the air supply device 100 itself to receive the environment information of the outdoor air from the air supply device 100, or may be configured not to be provided in the air supply device 100 and to receive information from a server (not shown) of an external operator connected via a wired/wireless communication network.
the exhaust fans 30, 31, and 32 may be manually operated according to a user's selection, or may be configured to be automatically operated based on the indoor environment information sensed by the first to third indoor environment sensing parts 210, 220, and 230. As an example, the indoor environment information may be a degree of pollution of indoor air.
The first to third indoor environment sensing parts 210, 220 and 230 are used to sense whether air in the kitchen 20, the bathroom 126 and the bathroom 227 is polluted, and may include an odor sensor (not shown) or a humidity sensor (not shown), for example.
As an example of a method for automatically operating the exhaust fans 30, 31, and 32 provided in the kitchen 20 or the bathrooms 26 and 27, the exhaust fans 30, 31, and 32 may be configured to be automatically operated according to a sensing signal of an odor sensor (not shown) capable of sensing odor generated during cooking or during use of the bathroom.
In order to discharge moisture in the bathrooms 26 and 27 to the outside after showering, the exhaust fans 30, 31 and 32 may be configured to be automatically operated according to a sensing signal of a humidity sensor (not shown) capable of sensing humidity in the bathrooms 26 and 27.
In this case, the odor sensor and the humidity sensor are formed as separate components from the exhaust fans 30, 31, 32 and the air supply device 100, and can be arbitrarily set at a suitable position in the kitchen or the toilet by the user.
the first to third indoor environment sensing parts 210, 220, and 230 may be configured to sense pollutants such as gas contained in the air.
The exhaust fans 31, 32 may include a communication function, and may communicate with the communication part 120 of the air supply device 100 to transmit the operation information of the exhaust fans 31, 32 to the air supply device 100, and may also transmit the operation information of the air supply device 100 to the exhaust fans 31, 32.
The first to third indoor environment sensing parts 210, 220, and 230 may be configured to transmit the sensed degree of contamination of the air to the air supply device 100 instead of the exhaust fans 31 and 32. In this case, the air supply device 100 may judge the degree of pollution of the air from the received degree of pollution information to adjust the amount of supplied air, or may also send a signal to the exhaust fans 30, 31, 32 to adjust the amount of exhausted air.
Fig. 3 is a diagram illustrating an air supply method according to an embodiment of the present invention, in which a bathroom mode is operated during a kitchen mode.
The kitchen mode indicates a mode in which the user supplies outdoor air to the kitchen 20 in a state in which the kitchen 20 cooks and operates the exhaust fan 30. The bathroom mode represents a mode in which air of the living room 21 or the bedroom 22, which is a second indoor space adjacent to the first indoor space, is supplied to the bathrooms 26, 27 in a case where the user uses the bathrooms 26, 27, which are the first indoor spaces, and operates the exhaust fans 31, 32. Also, in the case where the indoor space adjacent to the bathroom 227 is a changing room 24, the second indoor space may also be the changing room 24.
In step S101, the kitchen mode is operated. The user cooks and operates the exhaust fan 30. In this case, the air supply device 100 operates in the air supply mode in which the outdoor air is supplied to the kitchen 20 through the air supply ducts 41, 41 in a state in which the first damper 71 is open and the second damper 72 is closed. Accordingly, the contaminated air of the kitchen 20 is prevented from being diffused to other indoor spaces, and a severe negative pressure is prevented from being formed in the kitchen 20, thereby achieving smooth discharge of the contaminated air, so that exhaust efficiency can be improved, and noise and vibration can be prevented from being generated. In addition, when the kitchen mode is operated, the outdoor air can be intensively supplied to the kitchen 20 by closing the second damper 72, and thus the exhaust efficiency of the kitchen 20 can be further improved.
Of course, when the kitchen mode is not operated but the bathroom mode is operated first, step S102 may be directly executed without step S101.
In step S102, the bathroom mode is operated. When the user operates the exhaust fans 31 and 32 using the bathroom, the internal spaces of the bathrooms 26 and 27 are in a negative pressure state. Thus, air of the living room 21 or the bedroom 22 is supplied to the bathrooms 26, 27 through the connecting ducts 51, 61. Alternatively, the connection dampers 52, 62 are opened by a pressure difference or by a control signal of the control section 130 of the air supply device 100, so that the air of the living room 21 or the bedroom 22 is supplied to the bathrooms 26, 27. Therefore, the contaminated air in the bathrooms 26 and 27 can be smoothly discharged, the exhaust efficiency can be improved, and the generation of noise and vibration can be prevented. Further, since air is supplied by using air in the living room 21 or the bedroom 22, which is an indoor space, discomfort can be prevented from being given to the users of the bathrooms 26 and 27.
In step S103, the control unit 130 receives the environmental information of the outdoor air. The control unit 130 may operate any one of the air supply exclusive mode of step S105, the ventilation mode of step S107, and the air supply blocking mode of step S109 based on the received environment information of the outdoor air.
The environmental information of the outdoor air may be one or more of the temperature, humidity, and dust concentration of the outdoor air, and hereinafter, the description will be given with reference to the case where the environmental information of the outdoor air is the temperature in steps S104 to S109.
In step S104, when the season is the season change period or the outdoor temperature is a temperature corresponding to the season change period, the air supply dedicated mode can be operated because the difference between the temperatures of the outdoor air and the indoor air is not large. If the air supply dedicated mode is operated in step S105, outdoor air is supplied to the living room 21 or the bedroom 22, and air in the living room 21 or the bedroom 22 is supplied to the bathrooms 26 and 27. In this case, the outdoor air may be supplied to the living room 21 or the bedroom 22 after being heated by the heating part 161 or cooled by the cooling part 162. In this case, the air supply dedicated mode may also be configured to supply outdoor air directly to the bathrooms 26, 27, instead of to the living room 21 or the bedroom 22.
In step S106, when the season is winter/summer or the outdoor temperature is a temperature corresponding to winter/summer, the ventilation mode may be operated because the temperature difference between the outdoor air and the indoor air is large. When the ventilation mode is operated in step S107, the air in the living room 21 or the bedroom 22 is discharged to the outside, and the outdoor air is supplied to the living room 21 or the bedroom 22. In this case, the supply amount of outdoor air supplied from the air supply device 100 to the indoor is made larger than the discharge amount of indoor air discharged to the outdoor, so that the air supply mode can be realized. Further, the heat efficiency can be improved by performing heat exchange between the outdoor air and the indoor air in the heat exchange unit 150 of the air supply device 100. The outdoor air may be heated by the heating unit 161 or cooled by the cooling unit 162 and then supplied to the living room 21 or the bedroom 22.
When the ventilation mode is operated as described above, the air in the living room 21 or the bedroom 22 is ventilated with the outdoor air, and the air in the living room 21 or the bedroom 22 is supplied to the bathrooms 26 and 27. At this time, even if the air temperature of the living room 21 or the bedroom 22 slightly drops or rises due to the temperature of the outdoor air supplied to the living room 21 or the bedroom 22, the degree of the temperature change is not large because it is mixed with the air existing in the living room 21 or the bedroom 22. Further, the temperature change can be minimized by heat exchange in the heat exchange unit 150, heating in the heating unit 161, or cooling in the cooling unit 162. Therefore, even if such air is supplied to the bathrooms 26, 27, discomfort is not caused to the user.
In step S108, in the case where the season is the winter season/the summer season or the outdoor temperature is a temperature corresponding to the winter season/the summer season, since the temperature difference between the outdoor air and the indoor air is very large, the air supply blocking mode may be maintained. In the air supply blocking mode state of step S109, the outdoor air is not supplied to the living room 21 or the bedroom 22 by the air supply device 100, but the air existing in the living room 21 or the bedroom 22 is supplied to the bathrooms 26, 27. In this case, since outdoor air is not supplied to the living room 21 or the bedroom 22, the air supplied to the bathrooms 26, 27 is not affected by the temperature of the outdoor air. Therefore, discomfort is not caused to the user.
Since the supply air blocking mode indicates a state where the outdoor air is not supplied to the indoor spaces 20 to 25, the following operation air cleaning mode may be configured: indoor air is filtered in a state where the supply of outdoor air to the indoor is blocked, and then the air is circulated again to the indoor space.
As an example of a method of determining whether or not the temperature corresponds to each season, there is a method of dividing the temperature range into at least three ranges with reference to at least two set temperatures. That is, the following configurations are possible: the method includes the steps of judging to be a season change period/summer/winter when the temperature of outdoor air is between a first set temperature and a second set temperature higher than the first set temperature, and then operating an air supply dedicated mode or an air exchange mode as an air supply mode, and judging to be a cold winter period/summer cool period when the outdoor temperature is lower than the first set temperature or higher than the second set temperature, and then operating an air supply blocking mode. In this case, when the air supply exclusive mode and the ventilation mode are distinguished, the third set temperature and the fourth set temperature higher than the third set temperature are set between the first set temperature and the second set temperature, and further, three temperature sections are set between the third set temperature and the fourth set temperature, and the three temperature sections may be set to temperatures corresponding to winter/season change/summer.
In the steps S104 to S109, the case of performing control based on the temperature of the outdoor air is exemplified, but control based on the humidity of the outdoor air or the dust concentration of the outdoor air may also be performed.
That is, the air supply exclusive mode or the ventilation mode may be controlled when the humidity of the outdoor air is within the set range, and the air supply blocking mode may be controlled when the humidity of the outdoor air is outside the set range.
Further, the air supply exclusive mode or the ventilation mode may be controlled when the dust concentration of the outdoor air is within the set range, and the air supply blocking mode may be controlled when the dust concentration of the outdoor air is out of the set range.
In each of the steps S104 to S109, all of the first damper 71 and the second damper 72 may be opened. Further, the present invention may be configured such that: in the case where the kitchen 20 and the living room 21 constitute a communicating space, the first damper 71 is closed and only the second damper 72 is opened, so that the outdoor air is supplied to the kitchen 20 through the living room 21.
In step S110, when the exhaust fans 30, 31, 32 are stopped, the air supply mode or the air supply blocking mode is ended.
fig. 4 is a method of supplying air according to another embodiment of the present invention, which illustrates a case where the kitchen mode is operated during the bathroom mode.
The process from step S201 to step S208 is the same as the process from step S102 to step S109 in the embodiment of fig. 3, and thus detailed description is omitted.
In step S209, it is determined whether or not the kitchen mode is operated during the bathroom mode operation of steps S201 to S208. If the determination result is the kitchen operation mode, step S210 is performed.
In step S210, the air supply device 100 may be operated in any one of the air supply dedicated mode and the ventilation mode according to the environmental information of the outdoor air.
That is, when the season is the season change period or the outdoor temperature is a temperature corresponding to the season change period, the outdoor air is supplied to the kitchen 20, the living room 21, and the bedroom 22 by the air supply device 100 in the air supply dedicated mode of step S204. The supply of air to the bathrooms 26, 27 is effected by means of air supplied to said living room 21 or bedroom 22.
When the season is winter/summer or the outdoor temperature is a temperature corresponding to winter/summer, the air in the kitchen 20, the living room 21, and the bedroom 22 is discharged to the outside and the outdoor air is supplied to the kitchen 20, the living room 21, and the bedroom 22 while the ventilation mode in step S206 is operated. The air supply to the bathrooms 26, 27 is effected by means of the ventilating air of the living room 21 or the bedroom 22.
Also, in the case where the season is the winter season/the summer season or the outdoor temperature is a temperature corresponding to the winter season/the summer season, the air supply blocking mode of step S208 is interrupted and the air supply apparatus 100 may operate the air supply dedicated mode or the ventilation mode. In this case, outdoor air is supplied to the kitchen 20, the living room 21, and the bedroom 22, and air supply to the bathrooms 26 and 27 is realized by the air in the living room 21 or the bedroom 22.
In this case, as well, as shown in fig. 3, the air supply exclusive mode or the ventilation mode may be controlled in the case where the humidity or the dust concentration of the outdoor air is within the set range, and the air supply blocking mode may be controlled in the case where the humidity or the dust concentration of the outdoor air is out of the set range.
When the exhaust fans 30, 31, 32 are stopped, the air supply exclusive mode or the ventilation mode is ended.
If the air is supplied through the process as described above, various air supply modes can be implemented according to the state of the outdoor air, thereby improving the convenience of the user. When one or more of the temperature, humidity, and dust concentration of the outdoor air is in a bad state, the supply of air is performed by using the air of the other indoor space adjacent to the bathrooms 26 and 27, so that the user can be prevented from being uncomfortable with the supplied air.
Fig. 5 is a diagram illustrating a case where a bathroom mode is operated during a kitchen mode according to a further embodiment of the present invention.
the embodiment of fig. 3 describes a case where the kitchen mode and the bathroom mode are operated simultaneously. In this case, air in the living room 21 or the bedroom 22 communicating with the kitchen 20 is supplied to the bathrooms 26 and 27, and air in the kitchen 20 moves to the living room 21 or the bedroom 22, so that even if outdoor air is supplied to the kitchen 20, sufficient positive pressure is not formed in the kitchen 20 and the living room 21 or the bedroom 22 adjacent thereto. Therefore, the exhaust efficiency of the kitchen 20 is reduced, and contaminated air may be diffused toward the living room 21 or the bedroom 22. Also, contaminated air from the kitchen 20 may flow into the bathrooms 26, 27 through the living room 21 or the bedroom 22.
to solve such a problem, step S301 to step S306 are performed.
In step S301, the user cooks and operates the exhaust fan 30, thereby operating the kitchen mode.
In step S302, during the kitchen mode, the user uses the bathroom and operates the exhaust fans 31 and 32 of the bathrooms 26 and 27.
In step S303, when the exhaust fans 31 and 32 of the bathrooms 26 and 27 are operated, the connection dampers 52 and 62 are closed, and the supply of air in the living room 21 or the bedroom 22 to the bathrooms 26 and 27 is closed. By blocking the supply of air to the bathrooms 26 and 27 as described above, sufficient air supply to the kitchen 20 is achieved, and a sufficient positive pressure can be applied to the kitchen 20 and the living room 21 and the bedroom 22 communicating therewith, so that the contaminated air can be prevented from diffusing, and the exhaust efficiency of the kitchen 20 can be improved. Also, contaminated air in the kitchen can be prevented from flowing into the bathrooms 26, 27.
In step S304, it is determined whether or not the setting condition is satisfied. The set condition may be configured to be a case where the contamination level of the kitchen 20 sensed from the first indoor environment sensing part 210 is low below a preset level. Further, since it can be determined that a sufficient positive pressure is formed when the supply of outdoor air to the kitchen 20 is performed for a predetermined time in a state where the supply of air to the bathrooms 26 and 27 is blocked, the setting condition may be configured such that a predetermined time elapses after the exhaust fans 31 and 32 of the bathrooms 26 and 27 are operated.
In step S305, if the setting condition is satisfied, the connection dampers 52 and 62 are opened, and the air in the living room 21 or the bedroom 22 is supplied to the bathrooms 26 and 27.
In step S306, it is determined whether or not the operation of the exhaust fans 30, 31, 32 is stopped. If 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 ended.
By the air supply method as described above, the exhaust efficiency of the kitchen 20 can be improved, and contaminated air of the kitchen 20 can be prevented from being supplied to the bathrooms 26, 27.
Although the present invention has been described in detail with reference to the preferred embodiments, the present invention is not limited to the embodiments described above, and can be implemented by being modified in various ways within the scope of the claims, the detailed description of the present invention, and the accompanying drawings, and these belong to the present invention.
