FIELD OF THE INVENTION
[0001] The present invention relates to an air conditioner and an operating method for the
same, and more particularly, to an air conditioner for automatically searching a plurality
of indoor units to automatically set addresses and names based on address data received
from the respective indoor units, and an operating method for the same.
BACKGROUND
[0002] Generally, an air conditioner is provided to perform cooling, heating, and air purification
and is installed to discharge chilled or hot air into indoor and to purify indoor
air for the purpose of making more comfortable indoor environment to human beings.
The air conditioner is operated by which an indoor unit having a heat exchanger and
an outdoor unit having a compressor and a heat exchanger are separately controlled
and an electric power to be supplied to the compressor and the heat exchanger is controlled.
[0003] In the air conditioner, a plurality of indoor units can be connected to a single
outdoor. The outdoor unit is driven corresponding to the number of driven indoor units
to supply refrigerant to the indoor units based on required operating mode so that
the air conditioner is operated in a cooling mode or a heating mode.
[0004] The air conditioner further includes a remote controller for integrally controlling
the plurality of indoor units and the outdoor unit from a remote place so that the
indoor units and the outdoor unit are monitored and controlled.
[0005] In this case, the remote controller assigns a centralized controlling address. In
a case of automatically assigning an address to an indoor unit in a conventional method,
it is not easy to check what indoor units are indicated by a list displayed on a screen
of the remote controller.
[0006] In order to solve the problem, names of the respective indoor units listed in the
remote controller are inputted to distinguish the indoor units, but it is inconvenient
because the list of the indoor units must be matched with actual indoor units.
SUMMARY OF THE INVENTION
[0007] It is an object of the present invention to provide an air condition, when a remote
controller assigns addresses of a plurality of indoor units, for setting the addresses
of the indoor units based on address data received from the respective indoor units
when searching the indoor units and for automatically assigning a name of a corresponding
indoor unit so that it is convenient to assign the addresses, for the remote controller
to easily distinguish the indoor units, and convenience can be enhanced, and an operating
method thereof.
[0008] The present invention provides an air conditioner, comprising: at least one outdoor
unit (O); a plurality of indoor units (T) connected to the outdoor unit (O); and a
remote controller (RC) for controlling the outdoor unit (O) and the indoor units (I),
for sequentially requesting address data to the plural indoor units (I) to be connected,
for assigning address information contained in the address data as centralized controlling
addresses of the indoor units (I), and for automatically assigning and displaying
names of the indoor units (I) based on the address information.
[0009] Furthermore, the present invention provides an operating method of an air conditioner,
comprising: searching at least one connected indoor unit when an address assigning
command is inputted to a remote controller (RC) for centralized-controlling an outdoor
unit (O) and an indoor unit (I), and requesting address data to any one indoor unit
(I) of the searched indoor units to receive the requested address data from the indoor
unit (I); assigning address information contained in the address data as a centralized
controlling address for the indoor unit (I) and automatically assigning a name of
the indoor unit (I); and displaying the name of the indoor unit (I) on a screen and
communicating with the indoor unit (T) using the centralized controlling address.
[0010] According to the air conditioner and the operating method thereof according to the
present invention, the addresses are assigned based on the address data received from
the plurality of indoor units by which the remote controller searches the indoor units
and the names of the indoor units are automatically assigned. Therefore, it is not
required to match actual indoor units with the list of the indoor units of the remote
controller so that undesired efforts for that can be reduced. Since the remote controller
easily distinguishes the respective indoor units, a user can conveniently use and
the control and management of the plural indoor units are remarkably improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Hereinafter, embodiment of the present invention will be described with reference
to the accompanying drawing in detail.
[0013] FIG. 1 is a view showing the construction of an air conditioner in accordance with
an embodiment of the present invention.
[0014] The air conditioner according to the embodiment of the present invention, as illustrated
in FIG. 1, includes a remote controller RC, an outdoor unit O, indoor units I (I1
to I4), and local controllers R (R1 to R4).
[0015] At least one of the indoor units I is installed and includes an indoor heat-exchanger,
an indoor fan, an expansion valve in which refrigerant supplied from the outdoor unit
is expanded, and a plurality of temperature sensors.
[0016] The outdoor unit O is connected to the indoor units I, and includes a compressor
for receiving and compressing the refrigerant, an outdoor heat-exchanger for performing
heat-exchange between the refrigerant and outdoor air, an accumulator for extracting
gas refrigerant from the supplied refrigerant and for supplying the extracted gas
refrigerant to the compressor, and a four-way valve for selecting a passage for the
refrigerant corresponding to a heading operation. The outdoor unit O further includes
a plurality of pressure sensors for measuring a pressure of the refrigerant discharged
from the compressor, temperature sensors, a plurality of sensors, valves, and an oil
recovery, but the description for the components will be omitted in the following
description.
[0017] The outdoor unit O and the indoor units I are connected through a refrigerant pipe
to perform a cooling operation or a heating operation based on the flow of the refrigerant
between the outdoor unit and the indoor units. In this case, the outdoor unit O and
the indoor units I transmit and receive data in a preset communication method.
[0018] The outdoor unit O is driven by any one demand of at least one of the plural indoor
units, and the number of the outdoor units and the number of compressors installed
in the outdoor units are changed when the cooling capacity is changed in response
to the driven indoor units.
[0019] The remote controller RC is connected to the indoor units I and the outdoor unit
O and transmits and receives data in a preset communication method to monitor and
control the indoor units I and the outdoor unit O. In this case, a plurality of remote
controllers RC may be connected to the indoor units I and the outdoor unit O or may
be connected to each other through Internet.
[0020] The local controller R is connected to at least one of the indoor units I1 to I4,
changes the operation mode of the indoor unit according to an input by a user, and
receives and outputs the operation status of the corresponding indoor unit. Wire local
controller connected to the indoor units may be used as the local controllers R, alternately
wireless local controller may be used according to circumstances.
[0021] In this case, the air conditioner may further include a ventilation device and an
air purifier in addition to the indoor units and the outdoor unit, but the description
will be omitted. Although an example in which a single outdoor unit is connected and
the local controller R is connected to the single indoor unit is described, the number
of the outdoor units connected to the air conditioner, the number of the indoor units,
and the number of the indoor units connected to a single local controller R may be
changed.
[0022] FIG. 2 is a block diagram showing a configuration of a remote controller of the air
conditioner according to an embodiment of the present invention.
[0023] The remote controller RC, as illustrated in FIG. 2, includes a control unit 30, a
data unit 40, a communication unit 60, an input unit 10, an output unit 20, and an
address assigning unit 50.
[0024] The input unit 10 includes at least one button or a touch input unit or both of the
button and the touch input unit according to circumstances. The input unit 10 applies
a user's command inputted by manipulating the above-mentioned input unit to the control
unit 30.
[0025] The output unit 20 includes a display device for outputting texts and images, and
outputs the user's command inputted through the input unit 10 to a screen corresponding
to an operation corresponding to the inputted user's command. Moreover, the output
unit 20 displays the operation status of the plural indoor unit I1 to I4 received
through the communication unit 60, and displays a control menu and a schedule setting
menu for controlling the indoor units I1 to I4 on the screen.
[0026] The output unit 20 may further include a speaker for outputting an effective sound,
an alarming sound, and vocal guide, and a lamp to be turned on and off in addition
to the display device.
[0027] The data unit 40 stores data inputted by the input unit 10, data received from the
indoor units I1 to I4 and the outdoor unit O through the communication unit 60, control
data for controlling a unit including an indoor unit and an outdoor unit, and setting
data for controlling the outdoor unit and the indoor units. Moreover, the data unit
40 stores schedule data for the indoor units, the outdoor unit, and another unit to
be set by the control unit 30 in response to the user's command of the input unit
10. The data unit 40 stores control unit address data in which address data of the
respective indoor units match with the names of the indoor units.
[0028] The communication unit 60 includes a plurality of communication modules for transmitting
and receiving data in the wire and wireless communication lines, and transmits and
receives the data from and to the outdoor unit O and the indoor units I1 to I4 in
a desired communication line to apply the data to the control unit 30.
[0029] The control unit 30 controls the data transmitted and received through the communication
unit 60 and controls data to be inputted and outputted such that data inputted by
the input unit 10 are outputted through the output unit 15. In this case, the control
unit 30 creates a control command for controlling the indoor units and the outdoor
unit in response to the user's command inputted from the input unit 10 and transmits
the control command to the communication unit 60.
[0030] In addition, the control unit 30 sets a schedule for the operations of the respective
indoor units and the outdoor unit and transmits the control command through the communication
unit 60 such that the respective indoor units or the outdoor unit are driven according
to the assigned schedule. In this case, the control unit 30 controls that a plurality
of schedules is set for the respective indoor units and the outdoor unit, the indoor
units are driven according to the schedules, and a corresponding schedule is stored
in the data unit 40.
[0031] When an address setting command or an address searching command is inputted, the
control unit 30 searches a connected indoor unit I and controls the address assigning
unit 50 such that an address is assigned. Particularly, when the air conditioner is
initially driven, when the remote controller is initially driven, or when information
for the connected indoor unit is not registered, the centralized controlling address
for the communication with and the transmission of a control signal to the respective
indoor units is assigned.
[0032] The address assigning unit 50, in response to the control command from the control
unit 30, searches a connected indoor unit I and assigns addresses to the respective
indoor units based on the address data received from the plural indoor units I. In
this case, the respective indoor units are assigned with addresses in advance and
the addresses are stored as the address data, and the address assigning unit 50 assigns
the centralized controlling address of a corresponding indoor unit according to the
address data received from the indoor unit.
[0033] Moreover, the address assigning unit 50 calls control unit address data stored in
the data unit 40, and compares the received address data with an address list of the
control unit address data to automatically assigns a name matched to the address data
as a name of the corresponding indoor unit.
[0034] In this case the address assigning unit 50 accesses all the indoor unit of which
connection is detected in peer to peer to receive the address data from the respective
indoor units and to assign addresses, and repeats the above operation to finish the
assigning of addresses to the plural indoor units.
[0035] The address assigning unit 50 sequentially accesses the plural indoor unit in peer
to peer manner to assign the addresses, stops the assigning of addresses to the corresponding
indoor unit when a certain indoor unit does not respond for a predetermined time,
and tries to assign an address of a next indoor unit. After assigning an address of
a final indoor unit, the address assigning unit 50 checks whether there is an indoor
unit of which address is not assigned and tries to assign an address to the corresponding
indoor unit again.
[0036] The address assigning unit 50 determines that the corresponding indoor unit has an
error when a specific indoor unit is not assigned with an address even after performing
the assigning of addresses for a predetermined times, and displays the error or excludes
the corresponding indoor unit from targets to be controlled by the remote controller
RC.
[0037] Here, the address assigning unit 50 transmits an address data request signal to the
indoor unit, assigns address information contained in the address data to be received
from the indoor unit as a centralized controlling address of a corresponding indoor
unit, and automatically assigns names of the respective indoor units based on the
control unit address data. In this case, the address data received from the indoor
unit include the address information assigned to the indoor unit, identification information
of the indoor unit, and information for a kind of the unit.
[0038] For example, when an address 01 is assigned to the first indoor unit I1 and is stored,
the remote controller RC accesses the first indoor unit I1 to request address data,
then the first indoor unit I1 transmits the stored address data to the remote controller
RC. At this time, the address assigning unit 50 assigns the address of the first indoor
unit I1 as '01' according to the address information '01' contained in the received
address data. Moreover, the address assigning unit 50 searches the address '01' from
the control unit address data and assigns the name assigned to the address '01' as
the name of the first indoor unit I1 when there are matched data. In this case, when
the name of the indoor unit assigned to '01' is '3-20', the name of the first indoor
unit I1 becomes '3-20'. As the occasion demands, the kind of the unit may be assigned.
That is, the ventilation device is assigned with a 'ventilation 3-51'.
[0039] Meanwhile, when there is no data matched with the address information of a corresponding
indoor unit in the control unit address data, or when there is address information
matched with the corresponding indoor unit but no an assigned name, the address assigning
unit 50 may assign a default name or an arbitrary name. moreover, when the control
unit address data is not in the data unit 40, the address assigning unit 50 may request
the indoor unit I or the outdoor unit O.
[0040] The address assigning unit 50, when the assigning of addresses is completed, transmits
a signal for informing the completion of assigning addresses to the control unit 30,
the control unit 30 controls the data unit 40 to store the address information assigned
to the respective indoor units. After this, the control unit 30 communicated with
the indoor units based on the assigned address information.
[0041] The names of the indoor unit assigned as described above are outputted on a control
screen of the output unit 20 as names assigned with a list of the indoor units based
on a control command.
[0042] FIG. 3 is a block diagram illustrating the structure of an indoor unit of an air
conditioner according to an embodiment of the present invention.
[0043] As illustrated in FIG. 3, the indoor unit I includes an indoor unit control unit
120, an indoor unit communication unit 150, an indoor unit input unit 130, an indoor
unit output unit 140, and an indoor unit data unit 110.
[0044] The indoor unit communication unit 150 includes at least one communication module
and transmits and receives data from and to the local controller R, the remote controller
RC, and the outdoor unit O in a preset communication manner.
[0045] The indoor unit input unit 130 includes at least one input device in which preset
data are inputted by pressing or touching and applies a command inputted from a user
to the indoor unit control unit 120. In this case, the indoor unit input unit 130
includes buttons, a switch, and a touch input device of a touch screen.
[0046] The indoor unit output unit 140 outputs an operating mode, an operation setting,
and an operation status of the indoor unit. The indoor unit output unit 140 includes
a display device for outputting texts. and may further include images, a lamp to be
turned on and off, and a speaker for outputting preset sound.
[0047] The indoor unit data unit 110 stores control data for controlling the indoor unit
and an address information unit 111 stores address information of the indoor unit
communication unit 150 communicating with another unit. In this case, the address
information unit 111 stores address data inputted from the indoor unit input unit
130 or the local controller R as well as an outdoor unit assigning address when an
address is separately assigned from the outdoor unit.
[0048] The indoor unit control unit 120 controls the address data to be transmitted to the
remote controller RC through the indoor unit communication unit 150 when the remote
controller RC requests the address data through the indoor unit communication unit
150. At this time, the indoor unit control unit 120 calls and transmits the stored
address data from the address information unit 111, and calls and transmits the data
in the connected local controller R when there is no data stored in the address information
unit 111.
[0049] Moreover, when the assigning of the address is completed by the remote controller
RC through the indoor unit communication unit 150, the indoor unit control unit 120
determines the address stored in the address information unit 111 is assigned as the
centralized controlling address, and controls the indoor unit communication unit 150
to perform the communication using the stored address for the communication with the
remote controller RC. Here, data of an address different from the stored address among
the data received from the remote controller RC is discarded, and data of the same
address is received such that a predetermined operation is performed.
[0050] FIG. 4 is a block diagram illustrating a configuration of a local controller of an
air conditioner according to an embodiment of the present invention.
[0051] As illustrated in FIG. 4, the local controller R includes a local control unit 220,
a local controller communication unit 230, a local controller input unit 240, a local
controller output unit 250, and a data storage 210.
[0052] The local controller communication unit 230 is connected to the indoor unit according
to a communication manner. In this case, when the local controller R is connected
to a single indoor unit, data are transmitted to the corresponding indoor unit and
data of the indoor unit are received. When the local controller R is connected to
plural indoor units, data are received from any one of the indoor units and the data
are transmitted to the plural indoor units.
[0053] The local controller input unit 240 includes at least one button to be pressed or
a touch input device in which a touch is inputted to input a user's command. In this
case, the local controller input unit 240 is able to input data for operation a status
of the connected indoor unit. The local controller input unit 240 can input address
data for the connected indoor unit.
[0054] When the address data are inputted through the local controller input unit 240, the
local control unit 220 transmits the input data to the indoor unit and stores the
corresponding data in the data storage 210. In this case, when the indoor unit requests
the address data, the local controller control unit 220 transmits the data stored
in the data storage 210. At this time, the local control unit 220 provides a menu
for inputting the address data.
[0055] The local controller output unit 250 includes a display device for displaying the
menu for setting an operation mode of the indoor unit, and outputs an operating status
of the indoor unit based on the data received from the indoor unit. In this case,
the local controller output unit 250 may further include a lamp and a speaker.
[0056] The data storage 210 stores the address data inputted by the local controller input
unit 240 by a control command of the local control unit 220, and stores a screen structure
data to be outputted through the local controller output unit 250 of the local controller
input unit 240 and control data to be transmitted to the indoor unit.
[0057] FIG. 5 illustrates an example of a control screen of the remote controller in FIG.
3.
[0058] As illustrated in FIG. 5, the remote controller RC displays an operation status of
a connected device through the display device of the output unit 20, and provides
a control menu such that a control setting for a corresponding device can be inputted.
[0059] The remote controller RC displays an operation mode, an operation status, setting
data, and information on current indoor status by icons 25 of indicating the indoor
units using at least one of images, emoticons, texts together with a name 26 of the
corresponding indoor unit. In this case, the name of the indoor unit is automatically
assigned when the addresses of the respective indoor units are assigned.
[0060] In other words, when to assign an address to the connected indoor unit I, the remote
controller RC analyses the address data received from the indoor unit to assign the
address information contained in the address data as the centralized controlling address
of a corresponding indoor unit, and searches the address information from the stored
control unit address data to automatically a name assigned to corresponding address
information as a name of the indoor unit and to display the same on the control screen
when there is matched data.
[0061] For example, when the second indoor unit I2 is connected and is an indoor unit at
a room No. 21, third floor and the address data are received from the indoor unit,
the address of the first indoor unit is assigned with '02' according to the address
information contained in the address data, and a name such as '3-21' or 'an air conditioner
3-21' is automatically assigned to the corresponding indoor unit when the name assigned
to '02' in the control unit address data is '3-21'.
[0062] However, as occasion demands, the displayed name may be changed by the user's input,
and the name cannot be changed when a locking mode is set.
[0063] Here, the address data received from the indoor unit I are data inputted by the user
by manipulating the indoor unit input unit 130 provided in the indoor unit I or the
local controller input unit 240 provided in the local controller R.
[0064] Moreover, in other region of the screen of the remote controller RC, a control menu
22 for changing the setting of an operation mode, temperature, air volume of a selected
indoor unit is displayed. In this case, when the ventilation device is further connected
to the air conditioner, a ventilation control menu 23 corresponding to the ventilation
device may be further displayed.
[0065] FIG. 6 is a front view illustrating the configuration of the local controller in
FIG. 5.
[0066] As illustrated in FIG. 6, a plurality of buttons B01 to B38 is provided in the local
controller input unit 240 of the local controller R and information on an indoor unit
connected to the local controller output unit 250 is displayed.
[0067] In this case, the plural buttons B01 to B38 are function keys and moving keys for
setting the operation of the indoor unit and are used as an input unit for inputting
information on the indoor unit as occasion demands. The local controller R provides
a menu through which a name and characteristics of the connected indoor unit are inputted,
the data of the indoor unit are inputted by combination of the plural buttons. The
data inputted by the button of the local controller are stored in the data storage
210 and are transmitted to the indoor unit I to be stored as data of assigning an
address.
[0068] The operation of the air conditioner according to the embodiment of the present invention
will be described as follows.
[0069] FIG. 7 is a flowchart illustrating an address assigning method of an air conditioner
according to the embodiment of the present invention.
[0070] As illustrated in FIG. 7, when the address data of the indoor unit are inputted through
the local controller R (S310), the local controller 220 stores the inputted data in
the data storage 210 and transmits the data to the indoor unit I through the local
controller communication unit 230 (S320).
[0071] Here, the indoor unit I stores the data received from the local controller R as the
address data in the indoor unit data unit 110 (S350).
[0072] Meanwhile, when the address assigning command or an address searching command is
inputted, the remote controller RC automatically searches a connected indoor unit
I (S420). At this time, an address for the communication between the remote controller
RC and the indoor unit I is not assigned, the connected indoor unit is searched and
address data are received from the respective indoor units.
[0073] Here, the remote controller RC sequentially accesses the searched plural indoor units
I and requests address data to the respective indoor unit I (S430). The remote controller
RC sequentially accesses the respective indoor units in peer-to-peer manner. In this
case, the order of the access may be an order of near communication line or searching
but is not limited to this.
[0074] When the remote controller RC is accesses (S360) and the request for the data on
the address assign is received, the indoor unit I calls the stores address data and
transmits the same to the remote controller RC. The indoor unit I determines whether
there are stored address data (S370), and requests the address data to the local controller
R when there is no data (S380).
[0075] By doing so, the local controller R calls the stored address data of the indoor unit
in response to the request of the indoor unit I (S330) and transmits the same to the
indoor unit (S340). When the address data are received from the local controller R
(S390), the indoor unit I transmits the address data to the remote controller RC (S400).
[0076] When the address data are received from the indoor unit I (S440), the remote controller
RC analyses the address data and assigns the address information as the centralized
controlling address of the corresponding indoor unit I. Moreover, the remote controller
RC searches data matched to the address information from the control unit address
data and automatically assigns the assigned name to the name of the corresponding
indoor unit (S450).
[0077] For example, when the address is 01, the remote controller assigns the address as
the address of the corresponding indoor unit based on the address data, and searches
data matched to '01' to assign the name '3-20' assigned to the data as the name of
the first indoor unit 11.
[0078] By doing so, in the control screen of the remote controller RC for the monitoring
and the control, the first indoor unit I1, as described with reference to FIG. 5,
displays 'air conditioner 3-20'. In this case, the air conditioner indicates the kind
of the first indoor unit I1 which can be changed according to the setting.
[0079] When the assigning of the first indoor unit I1 is completed, whether the assigning
of all the indoor unit is completed is checked (S460), the next indoor unit is accessed
to assign an address and a name of the next indoor unit as described above (S430 to
S460).
[0080] Here, when there is an indoor unit which does not respond, the remote controller
RC disconnects the access to the corresponding indoor unit after standby for a predetermined
time, and accesses the next indoor unit to perform the assigning of an address and
a name (S470).
[0081] When there is an indoor unit whose address is not assigned even after the data are
requested to all the indoor unit, the data request and the assigning of the address
are retried to the corresponding indoor unit, and the corresponding indoor unit is
determined to be malfunctioned and is excluded from controlling objects when the response
is not received after a predetermined times of the try.
[0082] When a new indoor unit is connected or the indoor unit excluded from the controlling
object is searched again, the remote controller RC assigns an address and a name to
the new indoor unit in the above-mentioned manner and adds the new indoor unit to
the controlling object. Meanwhile, when there is no address data in the indoor unit,
the remote controller RC may voluntarily assign an address and a name to the indoor
unit.
[0083] When the assigning of the address and the name is completed, the remote controller
RC stores the assigned address information and name (S480), and starts the communication
with the indoor unit. The respective indoor units I communicate with the remote controller
RC using the stored addresses (S410).
[0084] The remote controller RC displays the list of the entire connected indoor unit on
the control screen, and communicates with the respective indoor units using the assigned
addresses such that the operation status is outputted and the operation of the indoor
unit can be controlled. At this time, the automatically assigned names of the indoor
units are displayed on the control screen of the remote controller RC.
[0085] Although the air conditioner and the operating method thereof according to the present
invention have been described with reference to the embodiment shown in the drawings,
