[0048] The arithmetic processor 14 includes a first determining
unit 141, a second determining unit 142, a ventilation-path setting
unit 143, a ventilation-quantity calculating unit 144, an output
unit 145, and an air-conditioning controller 146. The arithmetic
processor 14 includes, as a main component, the CPU(s) mounted in
the computer. The arithmetic processor 14 is configured to execute
various programs to perform various processes. The various programs
are stored in the storage unit 13.
[0049] The first determining unit 141 is configured to determine
whether or not required cold energy can be acquired by ventilation
based on the environmental information acquired by the information
acquisition unit 11, the history of the weather information in the
first storage unit 131, the history of the indoor environmental
information in the second storage unit 132, and the control log in
the third storage unit 133. That is, the first determining unit 141
is configured to determine whether or not it is appropriate that
only the ventilation operates in the case where the operation of
the air conditioner 3 is stopped.
[0050] The second determining unit 142 is configured to compare the
room temperature with the outside air temperature acquired by the
information acquisition unit 11 when the first determining unit 141
determines that the required cold energy cannot be acquired only by
ventilation. Then, the second determining unit 142 is configured to
determine whether or not the room temperature is higher than the
outside air temperature.
[0051] The ventilation-path setting unit 143 is configured to set
the ventilation path in the room 80 (see FIGS. 2 and 3) based on
the environmental information acquired by the information
acquisition unit 11, and the history information stored in the
storage unit 13. The ventilation-path setting unit 143 of the
present embodiment is configured to set the ventilation path in the
room 80 by executing the ventilation-path setting program for
setting the ventilation path. When the ventilation-path setting
program is executed, building information about room arrangement
(including positions of the first to third openings 81 to 83) in
the dwelling unit 8 is preliminarily input into the storage unit
13. The ventilation-path setting program is stored in the storage
unit 13.
[0052] When the second determining unit 142 determines that the
room temperature is higher than the outside air temperature, the
ventilation-path setting unit 143 sets the ventilation path 91 (see
FIGS. 2 and 3) in the state where the air conditioner 3 is
operated. Here, the ventilation-path setting unit 143 is configured
to set the ventilation path 91 in the room 80 to become different
from the path 92 (see FIGS. 2 and 3) of the wind emitted from the
air conditioner 3, in the state where the air conditioner 3 is
operating.
[0053] For example, when the path 92 of the wind sent from the air
conditioner 3 is a path to a central area in the room 80 from the
installed position of the air conditioner 3, the ventilation path
91 is set in a peripheral area that is not the central area in the
room 80. Therefore, the wind sent from the air conditioner 3 blows
to the central area in the room 80 from the installed position of
the air conditioner 3. The wind sent into the room 80 from the
outside of the room 80 through the first opening 81 blows the
peripheral area in the room 80 and blows outside the room 80
through the second opening 82. The relationship between the
ventilation path 91 and the path 92 is not limited to the
above-mentioned example.
[0054] The ventilation-quantity calculating unit 144 is configured
to calculate the ventilation quantity which passes through the
ventilation path set by the ventilation-path setting unit 143 using
the environmental information acquired by the information
acquisition unit 11, the ventilation path set by the
ventilation-path setting unit 143, and the hysteresis information
stored in the storage unit 13. The ventilation-quantity calculating
unit 144 of the present embodiment calculates the ventilation
quantity on a ventilation path by executing the
ventilation-quantity operation program for calculating ventilation
quantity. When the ventilation-quantity operation program is
executed, the building information about the room arrangement
(including positions of the first to third openings 81 to 83) in
the dwelling unit (building) 8 is input preliminarily. The
ventilation-quantity operation program is stored in the storage
unit 13.
[0055] The output unit 145 is configured to output the path
information indicating the ventilation path 91 (see FIGS. 2 and 3)
set by the ventilation-path setting unit 143, and the air-capacity
information indicating the ventilation quantity calculated by the
ventilation-quantity calculating unit 144 to the air-conditioning
controller 146.
[0056] The air-conditioning controller 146 is configured to control
the first opening device 21, the second opening device 22, and the
third opening device 23 according to the path information and the
air-capacity information that were outputted from the output unit
145. First, the air-conditioning controller 146 determines the
control content of the first opening device 21, the control content
of the second opening device 22, and the control content of the
third opening device 23 using the path information and the
air-capacity information which were outputted from the output unit
145. The air-conditioning controller 146 determines each control
content of the first opening device 21, the second opening device
22, and the third opening device 23 so that the ventilation path 91
through which the wind of the ventilation quantity passes actually
may be formed in the room 80 (see FIGS. 2 and 3). Then, the
air-conditioning controller 146 is configured to control the first
opening device 21, the second opening device 22, and the third
opening device 23 according to the control content. That is, the
air-conditioning controller 146 is configured to control directions
of louvers as the first to third opening devices 21 to 23 so that
the wind passes through the ventilation path 91 set by the
ventilation-path setting unit 143.
[0057] The control of the air-conditioning controller 146 is not
limited to the case where the whole wind from the room 80 to the
room 80 actually passes through the ventilation path 91. The
air-conditioning controller 146 is configured to control the first
opening device 21, the second opening device 22, and the third
opening device 23 so that the wind into the room 80 from the
outside of the room 80 passes through the ventilation path 91. That
is, the air-conditioning controller 146 is configured to control
the first to third opening devices 21 to 23 to flow the most wind
flows through the ventilation path 91.
[0058] The air-conditioning controller 146 is configured to control
the air conditioner 3. The air conditioner 3 works according to
control of the air-conditioning controller 146.
[0059] Incidentally, it may be preferable that the first opening
81, the second opening 82, and the third opening 83 are in the
closed states by the environmental information. That is, it may be
preferable that the ventilation is not to be performed by the
environmental information.
[0060] Then, the air-conditioning controller 146 makes the first
opening device 21 control opening and closing of the first opening
81 according to the environmental information acquired by the
information acquisition unit 11. The air-conditioning controller
146 makes the second opening device 22 control opening and closing
of the second opening 82 according to the environmental information
acquired by the information acquisition unit 11. The
air-conditioning controller 146 makes the third opening device 23
control opening and closing of the third opening 83 according to
the environmental information acquired by the information
acquisition unit 11.
[0061] When the second determining unit 142 determines that the
room temperature is higher than the outside air temperature, the
air-conditioning controller 146 is configured to control the first
to third opening devices 21 to 23 so that the first to third
openings 81 to 83 are to be opened. On the other hand, when the
second determining unit 142 determines the room temperature is
equal to or less than the outside air-conditioning temperature, the
air-conditioning controller 146 is configured to control the first
to third opening devices 21 to 23 so that the first to third
openings 81 to 83 are to be closed.
[0062] Incidentally, the ventilation path 91 may be preferable to
be near the ceiling 85 in the room 80 as the object space, as shown
in FIG. 2.
[0063] The ventilation-path setting unit 143 is configured to set
the ventilation path 91 so that the ventilation path 91 is near the
ceiling 85 in the room 80. That is, the ventilation-path setting
unit 143 is configured to set the ventilation path 91 so that the
ventilation path 91 is nearer the ceiling 85 than the wall 86 in
the room 80. First, the third acquisition unit 113 of the
information acquisition unit 11 is configured to acquire, as the
room-temperature information, information indicating the room
temperature at the area near the ceiling 85. Then, when the second
determining unit 142 determines that the room temperature at the
area near the ceiling 85 is higher than the outside air
temperature, the ventilation-path setting unit 143 is configured to
set the ventilation path 91 to be near the ceiling 85 in the room
80. The room temperature at the area near the ceiling 85 is not
temperature at the central area and an area along the wall 86 but
temperature at an area along the ceiling 85 in the room 80.
[0064] The ventilation path 91 may be preferable to be near the
wall 86 in the room 80, as shown in FIG. 3.
[0065] Then, the ventilation-path setting unit 143 is configured to
set the ventilation path 91 so that the ventilation path 91 may
serve as near the wall 86 in the room 80. That is, the
ventilation-path setting unit 143 is configured to set the
ventilation path 91 so that the ventilation path 91 is nearer the
ceiling 85 than the wall 86 in the room 80. First, the third
acquisition unit 113 of the information acquisition unit 11 is
configured to acquire the information indicating the room
temperature at the area near the wall 86 as the room-temperature
information. Then, when the second determining unit 142 determines
that the room temperature at the area near the wall 86 is higher
than the outside air temperature, the ventilation-path setting unit
143 is configured to set the ventilation path 91 so that the
ventilation path 91 is near the wall 86 in the room 80. The room
temperature at the area near the wall 86 is not temperature at the
central area and an area along the ceiling 85 but temperature at an
area along the wall 86 in the room 80.
[0066] Incidentally, it may be more preferable to use only the
ventilation, as to air conditioning of the room 80 as the object
space, compared with using the ventilation together with the air
conditioner 3. It is more preferable to use only the ventilation,
when required cold energy can be acquired only by the
ventilation.
[0067] Then, the ventilation-path setting unit 143 shown in FIG. 1A
is configured to set the ventilation path 91 in the state where an
operation of the air conditioner 3 is stopped, when the first
determining unit 141 determines that the required cold energy could
be acquired only by the ventilation. Then, the air-conditioning
controller 146 is configured to control the first to third opening
devices 21 to 23 according to the ventilation path 91 in the state
where the operation of the air conditioner 3 is stopped. The
air-conditioning controller 146 is configured to turn off the air
conditioner 3.
[0068] It may be more preferable to use only the air conditioner 3,
as to the air conditioning of the room 80 as the object space,
compared with using the air conditioner 3 together with the
ventilation. It is more preferable to use only the air conditioner
3, when the room temperature equal to or less than the outside air
temperature.
[0069] Then, when the second determining unit 142 determines the
room temperature is equal to or less than the outside air
temperature, the air-conditioning controller 146 is configured to
operate only the air conditioner 3 in the state where the
ventilation is stopped. In this case, the ventilation path 91 is
not set.
[0070] The storage unit 13 has stored not only the history of the
weather information mentioned above, the history of the indoor
environmental information, and the control log but also the various
kinds of information if needed.
[0071] The storage unit 13 is configured to store a program for
causing the ventilation control device (computer) 1 to perform
various functions. That is, the storage unit 13 is configured to
store a program(s) that causes the ventilation control device 1 to
function as the first determining unit 141, the second determining
unit 142, the ventilation-path setting unit 143, the
ventilation-quantity calculating unit 144, the output unit 145, and
the air-conditioning controller 146. The program is preliminarily
stored in the storage unit 13 at the time of shipment of the
ventilation control device 1. However, when the ventilation control
device 1 acquires the program after shipment, as an example of the
technique with which the ventilation control device 1 acquires the
program, there is a technique using the computer-readable recording
medium that stores the program. In the case of the technique using
the computer-readable recording medium, the ventilation control
device 1 needs only to include a reader (not shown) for reading
data in the recording medium. Examples of the recording medium
include an optical disc and a memory card. Examples of the reader
include a drive device configured to read out information on the
optical disc, and a memory card reader configured to read out
information on the memory card. As another techniques with which
the ventilation control device 1 acquires the program, there is a
technique with which the ventilation control device 1 downloads the
program from another device (for example, server) through a
network. In the case of the technique of downloading the program,
the ventilation control device 1 needs only to have a communication
function for communicating with the above-mentioned other device
through the network.
[0072] Next, a ventilation control method with the ventilation
control device 1 according to the present embodiment will be
described with reference to FIG. 4. The ventilation control method
is performed by executing the program stored in the storage unit 13
of the ventilation control device 1.
[0073] First, the information acquisition unit 11 acquires the
environmental information (S1). Then, the first determining unit
141 of the arithmetic processor 14 determines whether or not
required cold energy can be acquired by the ventilation based on
the environmental information acquired in Step S1, the history of
the weather information in the first storage unit 131, the history
of the indoor environmental information in the second storage unit
132, and the control log in the third storage unit 133 (S2).
[0074] When the required cold energy can be acquired only by the
ventilation (Yes at S2), the air-conditioning controller 146 is
configured to make the air conditioner 3 be in the off state and
control the first to third opening devices 21 to 23 so that the
first to third openings 81 to 83 is opened (S3). In this time, the
air-conditioning controller 146 suitably changes directions of
louvers as the first to third opening devices 21 to 23 to make a
wind direction so that wind spreads round the whole room 80. When
the required cold energy can be acquired only by the ventilation,
since the air-conditioning by the air conditioner 3 is not
required, the air conditioner 3 does not operate.
[0075] On the other hand, when the required cold energy cannot be
acquired only by the ventilation (No at S2), the second determining
unit 142 determines whether or not the room temperature T1 at an
area near the ceiling 85 is higher than the outside air temperature
T2 (S4).
[0076] When the room temperature T1 at the area near the ceiling 85
is higher than the outside air temperature T2 (Yes at S4), the
ventilation-path setting unit 143 sets the ventilation path 91 (see
FIG. 2) in the state where the air conditioner 3 is operating. The
ventilation-path setting unit 143 sets the ventilation path 91 to a
path along the ceiling 85 (see FIG. 2). The ventilation-quantity
calculating unit 144 calculates the ventilation quantity of the
wind passing through the ventilation path 91. Then, the
air-conditioning controller 146 makes the air conditioner 3 be
turned on, and controls the first to third opening devices 21 to 23
so that the first to third openings 81 to 83 are to be opened (S5).
In this time, the air-conditioning controller 146 adjusts
directions of louvers as the first to third opening devices 21 to
23 to make a wind direction so that a wind passes along the ceiling
85.
[0077] In Step S4, when the room temperature T1 at the area near
the ceiling 85 is equal to or less than the outside air temperature
T2 (No at S4), the air-conditioning controller 146 makes the air
conditioner 3 be turned on, and controls the first to third opening
devices 21 to 23 so that the first to third openings 81 to 83 are
in closed states (S6). In this case, since the room temperature T1
cannot be lowered by the ventilation, the ventilation is not
performed.
[0078] Because the wind direction and wind speed outside the
dwelling unit (building) 8 to change every moment, the ventilation
control device 1 needs to switch a ventilation state (a ventilation
path, ventilation quantity) according to change of a wind direction
and a wind speed. The switching interval at which the ventilation
control device 1 switches the ventilation state is about 10
minutes, for example.
[0079] In Step S4, the second determining unit 142 may be
configured to determine whether or not the room temperature at the
area near the wall 86 instead of the room temperature at the area
near the ceiling 85 is higher than the outside air temperature. In
this case, the ventilation path 91 is turned into a path that
passes along near the wall 86.
[0080] The ventilation control device 1 according to the present
embodiment described above is configured to set the ventilation
path 91 in the object space (room 80) of the wind that flows in and
out through the plurality of openings (first to third openings 81
to 83) between the object space and the outside of the building
(dwelling unit 8). The air conditioner 3 performs air-conditioning
in the object space inside the building. The plurality of openings
is disposed in the building. The ventilation control device 1
includes the ventilation-path setting unit 143 and the output unit
145. The ventilation-path setting unit 143 is configured to set the
ventilation path 91 so that the ventilation path 91 in the object
space in the state where the air conditioner 3 is operating is
different from the path of the wind sent from the air conditioner
3. The output unit 145 is configured to output the path information
indicating the ventilation path 91 set by the ventilation-path
setting unit 143.
[0081] The ventilation system according to the present embodiment
includes the ventilation control device 1 and the plurality of
opening devices (first to third opening devices 21 to 23). The
plurality of opening devices respectively corresponds to the
plurality of openings (first to third openings 81 to 83) disposed
in the building (dwelling unit 8). Each of the plurality of opening
devices is configured to control the opening state of the
corresponding opening by control of the ventilation control device
1.
[0082] The program according to the present embodiment causes the
computer to function as the ventilation-path setting unit 143 and
the output unit 145. The program is a program for executing the
computer that is used in order to set the ventilation path 91 in
the object space (room 80) of the wind that flows in and out
through the plurality of openings (first to third openings 81 to
83) between the object space and the outside of the building
(dwelling unit 8). The air conditioner 3 performs air-conditioning
in the building. The plurality of openings is disposed in the
building. The ventilation-path setting unit 143 is configured to
set the ventilation path 91 so that the ventilation path 91 in the
object space in the state where the air conditioner 3 is operating
is different from the path 92 of the wind sent from the air
conditioner 3. The output unit 145 is configured to output the path
information indicating the ventilation path 91 set by the
ventilation-path setting unit 143.
[0083] In the ventilation system according to the present
embodiment, the ventilation control device 1 is configured to set
the ventilation path 91 in the room 80 as the object space in the
building (dwelling unit 8), of the wind flowing in and out through
the first to third openings 81 to 83 between the room 80 and the
outside of the building, so that the ventilation path 91 is
different from the path 92 of the wind sent from the air
conditioner 3. Therefore, in the ventilation control device 1
according to the present embodiment, even if cooling available by
the ventilation is not sufficient, it is possible that the air
conditioner 3 is used together with the ventilation without
stopping the ventilation and without the ventilation decreasing the
cooling by the air conditioner 3. Accordingly, because decreasing
load of the air conditioner 3, the ventilation control device 1 can
increase the energy conservation effect compared with the case
where only the air conditioner 3 is operated.
[0084] Preferably, the ventilation control device 1 further
includes the air-conditioning controller 146. The air-conditioning
controller 146 is configured to control the plurality of opening
devices (first to third opening devices 21 to 23) according to the
path information outputted from the output unit 145. The plurality
of opening devices respectively corresponds to the plurality of
openings (first to third openings 81 to 83). Each of the plurality
of opening devices is configured to control the opening state of
the corresponding opening.
[0085] Preferably, the ventilation control device 1 further
includes the information acquisition unit 11. The air-conditioning
controller 146 is preferably configured to perform the following
operation. The information acquisition unit 11 is configured to
acquire the environmental information. The environmental
information includes the outside-air-temperature information and
the room-temperature information. The outside-air-temperature
information indicates the outside air temperature T2 outside the
building (dwelling unit 8) The room-temperature information
indicates the room temperature T1 in the object space (room 80).
The air-conditioning controller 146 is configured to make the
plurality of opening devices (first to third opening devices 21 to
23) control opening or closing of the plurality of openings (first
to third openings 81 to 83) according to the environmental
information acquired by the information acquisition unit 11.
[0086] In the ventilation system according to the present
embodiment, the ventilation control device 1 is configured to make
the first to third opening devices 21 to 23 control the opening or
closing of the first to third openings 81 to 83 according to the
environmental information including the outside-air-temperature
information and the room-temperature information. Therefore, in the
ventilation control device 1 according to the present embodiment,
with the relation between the outside air temperature and the room
temperature, it is possible to perform the ventilation or stop the
ventilation.
[0087] The air-conditioning controller 146 preferably performs the
following operation. The air-conditioning controller 146 is
configured to control the plurality of opening devices (first to
third opening devices 21 to 23) so that the plurality of openings
(first to third openings 81 to 83) are to be opened when the room
temperature T1 is higher than the outside air temperature T2. The
air-conditioning controller 146 is configured to control the
plurality of opening devices so that the plurality of openings are
to be closed when the room temperature T1 is equal to or less than
the outside air temperature T2.
[0088] When the room temperature T1 is higher than the outside air
temperature T2, the ventilation control device 1 controls the first
to third opening devices 21 to 23 so that the first to third
openings 81 to 83 is in opened states. On the other hand, when the
room temperature T1 is equal to or less than the outside air
temperature T2, the ventilation control device 1 controls the first
to third opening devices 21 to 23 so that the first to third
openings 81 to 83 is in closed states. Therefore, in the
ventilation control device 1, the case where the air conditioner 3
and the ventilation are used together, and the case where only the
air conditioner 3 is used can be switched with the relation between
the room temperature T1 and the outside air temperature T2.
[0089] The ventilation-path setting unit 143 is preferably
configured to set the ventilation path 91 so that the ventilation
path 91 is near the ceiling 85 in the object space (room 80).
[0090] Further preferably, the ventilation control device 1 further
includes the information acquisition unit 11. The ventilation-path
setting unit 143 is preferably configured to perform the following
operation. The information acquisition unit 11 is configured to
acquire the environmental information. The environmental
information includes the outside-air-temperature information and
the room-temperature information. The outside-air-temperature
information indicates the outside air temperature T2 outside the
building (dwelling unit 8). The room-temperature information
indicates the room temperature T1 in the object space (room 80).
The information acquisition unit 11 is configured to acquire the
information indicating the room temperature T1 at the area near the
ceiling 85 as the room-temperature information. The
ventilation-path setting unit 143 is configured to set the
ventilation path 91 so that the ventilation path 91 is near the
ceiling 85 in the object space when the room temperature T1 at the
area near the ceiling 85 is higher than the outside air temperature
T2.
[0091] In the ventilation system according to the present
embodiment, the ventilation control device 1 can set the
ventilation path 91 so that the wind which flows in and out through
the first to third openings 81 to 83 may pass near the ceiling 85
in the room 80 as the object space. Therefore, in the ventilation
control device 1 according to the present embodiment, it is
possible to decrease the heat transmitted from the roof for example
into the room 80 through the ceiling 85.
[0092] The ventilation-path setting unit 143 is preferably
configured to set the ventilation path 91 so that the ventilation
path 91 is near the wall 86 in the object space (room 80).
[0093] More preferably, the ventilation control device 1 further
includes the information acquisition unit 11. The ventilation-path
setting unit 143 is more preferably configured to perform the
following operation. The information acquisition unit 11 is
configured to acquire the environmental information. The
environmental information includes the outside-air-temperature
information and the room-temperature. The outside-air-temperature
information indicates the outside air temperature T2 outside the
building (dwelling unit 8). The room-temperature information
indicates the room temperature T1 in the object space (room 80).
The information acquisition unit 11 is configured to acquire the
information indicating the room temperature T1 in the area near the
wall 86 as the room-temperature information. The ventilation-path
setting unit 143 is configured to set the ventilation path 91 so
that the ventilation path 91 is near the wall 86 in the object
space when the room temperature T1 in the area near the wall 86 is
higher than the outside air temperature T2.
[0094] The ventilation control device 1 of the present embodiment
can also set the ventilation path 91 so that the wind which flows
in and out through the first to third openings 81 to 83 may pass
near the wall 86 in the room 80 as the object space. Therefore, in
the ventilation control device 1 of the present embodiment, the
heat which has been transmitted into the room 80 via the wall 86
can also be lowered.
[0095] Each of the plurality of opening devices (first to third
opening devices 21 to 23) is preferably the louver disposed in the
corresponding opening. The air-conditioning controller 146 is
preferably configured to perform the following operation. The
air-conditioning controller 146 is configured to control the
direction of the louver so that the wind passes through the
ventilation path 91 set by the ventilation-path setting unit
143.
[0096] In the ventilation system according to the present
embodiment, the first to third opening devices 21 to 23 are
louvers. Therefore, in the ventilation control device 1 of the
present embodiment, the direction of the wind which comes into the
room 80 through the first to third openings 81 to 83 is easily
changeable in the direction of the ventilation path 91 by
controlling the directions of the louvers.
[0097] In the present embodiment, although the first acquisition
unit 111 of the information acquisition unit 11 acquires the wind
pertinent information from the anemometer 4, the first acquisition
unit 111 may be configured to acquire the wind pertinent
information from an external device (not shown) as a modification
of the present embodiment. The external device should just be a
device which acquires the wind pertinent information periodically
and holds it, for example.
[0098] Although the second acquisition unit 112 of the information
acquisition unit 11 acquires the outside air temperature and
outside air humidity from the first thermo-hygrometer 5 installed
outside the building in the present embodiment, as a modification
of the present embodiment, the second acquisition unit 112 may
acquire outside air temperature and outside air humidity from an
external device (not shown). The external device should just be a
device which acquires outside air temperature and outside air
humidity periodically and keeps them, for example.
[0099] Although the third acquisition unit 113 of the information
acquisition unit 11 is configured to acquire the indoor
environmental information from the second thermo-hygrometer 6
currently installed in the building in the present embodiment, the
third acquisition unit 113 may be configured to acquire the indoor
environmental information from an external device (not shown) as a
modification of the present embodiment. The external device should
just be a device which acquires the indoor environmental
information periodically and holds it, for example.
[0100] The output unit 145 may output the path information and
air-capacity information not only to the air-conditioning
controller 146 but to an alarming means (not shown) as a
modification of the present embodiment. In the case of this
modification, an alarming means reports a ventilation state (a
ventilation path, ventilation quantity) based on the path
information and the air-capacity information which were outputted
from the output unit 145. Therefore, it is possible to report, to a
person in-the-room, the ventilation state set in this time. The
information technique for reporting a ventilation state may be the
technique of displaying the ventilation state on a screen, and may
be the technique of outputting the ventilation state with a
sound.
[0101] Furthermore, in the present embodiment, although the
air-conditioning controller 146 controls the first to third opening
devices 21 to 23, as a modification of the present embodiment, the
output unit 145 may be configured to report the path information
and air-capacity information to the management device (not shown)
which manages the first to third opening devices 21 to 23. The
management device determines the control contents for the first to
third opening devices 21 to 23 using the ventilation state (a
ventilation path, ventilation quantity) set in this time, when the
management device acquires the path information and air-capacity
information from the output unit 145 in the case of this
modification. Then, the management device is configured to control
the first to third opening devices 21 to 23 according to the
control content.
[0102] Although the present invention has been described with
reference to a certain preferred embodiment, numerous modifications
and variations can be made by those skilled in the art without
departing from the true spirit and scope of this invention, namely
claims.
