Description
Technical Field
The present invention relates to an air conditioner, and more particularly, to an air conditioner capable of simultaneously performing a heating operation and a humidification operation, and a humidification operation method of the air conditioner.
Background
An air conditioner is an apparatus provided to provide a comfortable indoor environment by discharging low-temperature air into a room to adjust the indoor temperature and purify the indoor air.
The air conditioner is divided into an indoor unit disposed indoors and an outdoor unit disposed outdoors, and can cool or heat indoor air by a refrigerant circulating through the indoor unit and the outdoor unit.
The indoor unit of the separate type air conditioner is classified into a vertical type indoor unit installed vertically on an indoor floor, a wall-mounted type indoor unit installed to be hung on an indoor wall, a ceiling-mounted type indoor unit installed on an indoor ceiling, and the like according to an installation method.
In the related art, an air conditioner additionally having a humidification function is disclosed.
As an example, korean patent laid-open No. 10-1073637 discloses an air conditioner in which a humidifier is provided to facilitate temperature/humidity adjustment in a room. Such an air conditioner heats water by a heater and generates steam, and the steam is discharged into a room through a steam discharge port.
As another example, in korean patent laid-open No. 10-1894189, an air conditioner provided with a humidifier is disclosed. The humidifier includes a reservoir for storing water and a heater for heating the water in the reservoir. The amount of steam generated from the water stored in the storage tank is adjusted by adjusting the heating amount of the heater, thereby controlling the humidity of the air.
However, as in the above-described document, in the air conditioner that performs the humidification operation by heating water with the heater, more electric current required for the heater operation is consumed for heating the water.
In most of air conditioners having a large capacity, when heating operation is performed in a place of use, the operation is performed at a maximum current allowable value close to a circuit breaker.
In this case, when the air conditioner operates the heater to additionally perform the humidification operation during the heating operation, the maximum allowable current value of the circuit breaker is exceeded, and there is a possibility that the circuit breaker completely opens the current.

Disclosure of Invention
An object of the present invention is to provide a humidification operation method for an air conditioner, which can simultaneously perform a heating operation and a humidification operation.
It is another object of the present invention to provide a method for operating a humidifier of an air conditioner in which a circuit breaker does not interrupt current even if a humidification operation is additionally performed during a heating operation.
It is another object of the present invention to provide a method of operating a humidifier of an air conditioner that reduces the amount of current flowing through a compressor during humidification.
It is another object of the present invention to provide a humidification operation method of an air conditioner, which can stably perform a heating operation and a humidification operation by allowing an indoor unit and an outdoor unit to communicate with each other.
The object of the present invention is not limited to the above-mentioned object, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.
According to the present invention, since the humidified air is generated during the heating operation and is injected into the room through the independent flow path, the heating operation and the humidifying operation can be independently performed.
According to the present invention, since the heating operation can be performed during the heating operation and the heating operation can be performed during the humidification operation, the heating operation and the humidification operation can be performed simultaneously.
According to the present invention, when a request for a humidification operation is input during a heating operation, a current required for the humidification operation is secured by reducing a driving current of a compressor for performing the heating operation, and thus the operation can be stably performed without interrupting the current.
According to the present invention, when a request for heating operation is input during humidification operation, the compressor is driven by subtracting a predetermined amount of drive current from the drive current of the compressor for performing heating operation, thereby ensuring the current required for humidification operation.
According to the present invention, when requests for the heating operation and the humidification operation are sequentially input at the same time or at short time intervals, the compressor is driven by subtracting a predetermined amount from the drive current of the compressor required for the heating operation.
According to the present invention, in order to reduce the driving current of the compressor, the driving current can be stably reduced by a simple operation by reducing the operating frequency of the compressor.
According to the present invention, when the humidifying operation and the heating operation are simultaneously performed, the sum of the drive current of the compressor required in the heating operation and the drive current required in the humidifying operation is made smaller than the preset maximum current allowable value of the circuit breaker by reducing the drive current.
According to the present invention, after it is confirmed that the driving current of the compressor is reduced, the heater for performing the humidification operation is operated, thereby stably performing the operation.
According to the present invention, after the step of driving the compressor, whether the driving current is reduced is checked again in the outdoor unit, and if the result of the check is that the driving current is reduced, a command for reducing the driving current is transmitted to the indoor unit, thereby checking whether the driving current is reduced after the time consumed for reducing the driving current.
According to the present invention, the reduced drive current is used as the current consumed in the humidification operation, and therefore, a stable operation can be performed.
According to the present invention, when a request for stopping the humidification operation is input while the heating operation and the humidification operation are being performed, the drive current required for the current heating operation can be increased by a predetermined amount to drive the compressor.
According to the present invention, the compressor is driven by increasing the driving current required for the heating operation according to whether the humidification operation is stopped or not, and thus the operation can be performed efficiently.
The humidification operation method of an air conditioner according to the present invention has one or more of the following effects.
First, the present invention can simultaneously perform a heating operation and a humidifying operation, and thus can adjust the indoor humidity during heating.
Second, the present invention can provide a comfortable environment because it can simultaneously use the heating operation and the humidifying operation.
Thirdly, the present invention has an advantage of ensuring reliability of products because it does not operate by cutting off current even if humidification operation is additionally performed during heating operation.
Fourth, the present invention can perform the humidification operation by a simple current limitation of the compressor, and thus can ensure the stability of the humidification operation.
Fifth, according to the present invention, since the heater for performing the humidification operation is operated after checking whether the current of the compressor is reduced or not when the humidification operation is performed, there is an advantage that a stable operation can be performed.

Detailed Description
The advantages, features and methods of accomplishing the same will become more apparent from the following detailed description of the embodiments with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be embodied in various shapes different from each other, and the embodiments are provided only for the purpose of fully disclosing the present invention and fully disclosing the scope of the present invention to those skilled in the art, which is determined only by the scope of the appended claims. Like reference numerals denote like constituent elements throughout the specification.
The present invention will be specifically described below with reference to the accompanying drawings.
Fig. 1 is a diagram showing an external appearance of an air conditioner of an embodiment of the present invention.
Referring to fig. 1, the air conditioner 10 may include: an indoor unit 100 that is provided in an indoor space and exchanges heat between indoor air and a refrigerant; and an outdoor unit 200 installed in the outdoor space and configured to exchange heat between outdoor air and the refrigerant.
The indoor unit 100 may include: an indoor unit main body 110 forming an external appearance of the indoor unit 100; a front discharge port 111 and a side discharge port 121 which are provided on the front and side surfaces of the indoor unit main body 110 and discharge heat-exchanged air; and a display panel 113 for displaying operation information of the air conditioner 10.
The outdoor unit 200 may include: an outdoor unit main body 221 for forming an external appearance of the outdoor unit 200; and an outdoor unit discharge port 222 for discharging air from one side of the outdoor unit main body 221.
The outdoor unit 200 compresses a refrigerant or performs heat exchange according to an operation mode by operating a compressor and an outdoor heat exchanger provided therein, and supplies the compressed refrigerant or the heat exchange to the indoor units 100.
The outdoor unit 200 may be driven by a control signal of the indoor unit 100.
The outdoor unit 200 and the outdoor unit 200 may transmit and receive control signals and data to and from each other through wired or wireless communication.
Fig. 2 is a block diagram showing the structures of the indoor unit and the outdoor unit in fig. 1.
The outdoor unit 200 may include: a compressor 201 for compressing a refrigerant; an outdoor heat exchanger 202 for performing heat exchange between outdoor air and refrigerant; a four-way valve 203 for selectively guiding the refrigerant compressed in the compressor 201 according to the heating operation to any one of the outdoor heat exchanger 202 and the indoor unit 100; an outdoor expansion valve 204 that, during heating operation, decompresses the refrigerant guided to the outdoor heat exchanger 202; and an accumulator (205) for preventing liquid refrigerant that has not yet been vaporized from flowing to the compressor 201.
The compressor 201 compresses a low-pressure gas refrigerant into a high pressure by a rotational force of a compressor motor (not shown) that receives electric power from an external power supply and rotates.
The four-way valve 203 guides the refrigerant compressed in the compressor 201 to the outdoor heat exchanger 202 during the cooling operation, and guides the refrigerant compressed in the compressor 201 to the indoor unit 100 during the heating operation.
The outdoor heat exchanger 202 condenses the refrigerant compressed by the compressor 201 during the cooling operation, and evaporates the refrigerant decompressed by the indoor unit 100 during the heating operation.
The outdoor heat exchanger 202 may include a cooling fan 202a for blowing outdoor air toward the outdoor heat exchanger 202.
The outdoor expansion valve 204 may not only reduce the pressure of the refrigerant during the heating operation, but may also adjust the amount of refrigerant supplied to the outdoor heat exchanger 202 to achieve sufficient heat exchange in the outdoor heat exchanger 202.
The indoor unit 100 may include: an indoor heat exchanger 101 for performing heat exchange between indoor air and refrigerant; and an indoor expansion valve 102 for decompressing the refrigerant supplied to the indoor heat exchanger 101 during the cooling operation.
The indoor heat exchanger 101 evaporates a low-pressure liquid refrigerant during the cooling operation, and condenses a high-pressure gas refrigerant during the heating operation.
The indoor heat exchanger 101 may include a blowing fan 101a for blowing air heat-exchanged with the refrigerant in the indoor heat exchanger 101 toward the indoor.
The indoor expansion valve 102 not only reduces the pressure of the refrigerant, but also adjusts the amount of the refrigerant supplied to the outdoor heat exchanger 202 so as to perform sufficient heat exchange in the indoor heat exchanger 101.
Next, the flow of the refrigerant in the air-conditioning apparatus 10 during the heating operation will be described.
When the air conditioner 10 operates in the cooling operation, the refrigerant is compressed to a high pressure by the compressor 201 of the outdoor unit 200. The refrigerant is compressed and its pressure and temperature will increase together.
The compressed refrigerant is guided to the outdoor heat exchanger 202 via the four-way valve 125. The refrigerant guided to the outdoor heat exchanger 202 is condensed in the outdoor heat exchanger 202, and heat exchange will be achieved between the refrigerant and the outdoor air during the period in which the refrigerant is condensed.
Specifically, while the refrigerant is undergoing a state change from a gaseous state to a liquid state, the refrigerant discharges energy (latent heat) corresponding to the difference between the internal energy of the gaseous refrigerant and the internal energy of the liquid refrigerant to the outside of the room.
The condensed liquid refrigerant is supplied to the indoor unit 100 via the outdoor expansion valve 204.
The liquid refrigerant supplied to the indoor unit 100 is reduced in temperature and decompressed in the indoor expansion valve 102.
The indoor expansion valve 102 may be an electronic valve whose opening degree can be adjusted to adjust the amount of refrigerant flowing through the indoor heat exchanger 101 described later.
The liquid refrigerant whose pressure is reduced is evaporated in the indoor heat exchanger 101, and heat exchange is performed between the refrigerant and the indoor air while the refrigerant is evaporated.
Specifically, while the refrigerant changes its state from liquid to gas, the refrigerant absorbs energy (latent heat) from the indoor air, which corresponds to the difference between the internal energy of the gas refrigerant and the internal energy of the liquid refrigerant.
As described above, when the cooling operation is performed, the air conditioner 10 may cool the indoor air using heat exchange between the refrigerant and the indoor air occurring in the indoor heat exchanger 101 (i.e., a phenomenon in which the refrigerant absorbs latent heat from the indoor air).
The vaporized gaseous refrigerant is supplied to the outdoor unit 200, and is supplied to the accumulator 125 via the four-way valve 123. In the accumulator 125, liquid refrigerant that has not yet been vaporized and gaseous refrigerant that has been vaporized in the refrigerant are separated, and the gaseous refrigerant is re-supplied to the compressor 201.
The gaseous refrigerant supplied to the compressor 201 is compressed by the compressor 201, thereby repeating the above-described refrigerant cycle.
When the air conditioner 10 operates in the heating operation, the refrigerant is compressed to a high pressure by the compressor 201 of the outdoor unit 200, and the temperature of the refrigerant increases together with the pressure.
The compressed refrigerant passes through the four-way valve 125 and is then guided to the indoor unit 100.
The refrigerant is condensed in the indoor heat exchanger 101, and heat exchange is performed between the refrigerant and the indoor air while the refrigerant is condensed.
Specifically, while the refrigerant is undergoing a state change from a gas state to a liquid state, the refrigerant discharges energy (latent heat) corresponding to the difference between the internal energy in the gas state and the internal energy in the liquid state into the room.
As described above, the air conditioner 10 may heat the indoor air using heat exchange between the refrigerant and the indoor air (i.e., a phenomenon in which the refrigerant releases latent heat) occurring in the indoor heat exchanger 101 when performing the heating operation.
The condensed liquid refrigerant is re-supplied to the outdoor unit 200 after passing through the expansion valve 224.
The liquid refrigerant supplied to the outdoor unit 200 is decompressed by the outdoor expansion valve 204, and the temperature of the refrigerant is also decreased. The outdoor expansion valve 204 may be an electronic valve whose opening degree can be adjusted to adjust the amount of refrigerant flowing to the outdoor heat exchanger 202, which will be described later.
The decompressed liquid refrigerant is evaporated in the outdoor heat exchanger 202, and heat exchange is performed between the refrigerant and the outdoor air while the refrigerant is evaporated.
Specifically, while the refrigerant is undergoing a state change from a liquid state to a gaseous state, the refrigerant absorbs energy (latent heat) from the outdoor air that corresponds to the difference between the internal energy of the gaseous refrigerant and the internal energy of the liquid refrigerant.
The gaseous refrigerant evaporated in the outdoor heat exchanger 202 passes through the four-way valve 125 and is supplied to the accumulator 150. In the accumulator 150, liquid refrigerant that has not yet been vaporized and gaseous refrigerant that has been vaporized in the refrigerant are separated, and the gaseous refrigerant is supplied to the compressor 201.
The gaseous refrigerant supplied to the compressor 201 is compressed in the compressor 201, thereby repeating the cycle of the refrigerant.
Next, the signal flow of the components included in the air conditioner 10 will be described.
Fig. 3 is a diagram illustrating a signal flow direction between an outdoor unit and an indoor unit according to an embodiment of the present invention, and fig. 4 is a diagram illustrating a signal flow direction in the outdoor unit of fig. 3.
The indoor unit 100 and the outdoor unit 200 may perform wired or wireless communication with each other.
The indoor unit 100 can transmit a control signal required for operating the outdoor unit 200 and can receive a signal from the outdoor unit 200. The outdoor unit 200 can operate according to a control signal received from the indoor unit 100 and can transmit necessary information to the indoor unit 100.
The outdoor unit 200 and the indoor unit 100 can also transmit and receive control signals and data to and from an external remote control device (not shown) through wired or wireless communication.
The outdoor unit 200 may include: an outdoor unit communication unit 211 that performs wired or wireless communication with the indoor unit 100; an outdoor unit control unit 212 that controls the overall operation of the outdoor unit 200; a compressor driving unit 213 that generates a driving current for driving the compressor 201; and a cooling fan driving section 214 and a four-way valve driving section 215 that control driving of the cooling fan 202a and the four-way valve 203, respectively. Alternatively, the outdoor unit 200 may further include an outdoor unit operation unit 216, and the outdoor unit operation unit 216 is used for inputting an operation command of the outdoor unit 100 from a user.
The outdoor unit control unit 212 can receive operation information from the indoor unit 100 via the outdoor unit communication unit 211, and can output a predetermined control signal to the compressor driving unit 213 according to the received operation information.
The compressor driving unit 213 may generate a driving current corresponding to the control signal received from the outdoor unit control unit 212 and output the driving current to the compressor 201. The compressor 201 may be driven by the driving current output as described above.
The operation of the compressor 201 can be controlled according to an increase or decrease in the drive current output from the compressor drive unit 213. The load of the compressor 201 can be controlled by increasing or decreasing the drive current. For example, if the drive current is increased, the load on the compressor 201 may be increased, and conversely, if the drive current is decreased, the load on the compressor 201 may be decreased.
Further, increase or decrease of the driving current can be controlled according to increase or decrease of the operating frequency of the compressor 201. For example, when the operating frequency of the compressor 201 is decreased, the drive current of the compressor 201 can be decreased, and when the operating frequency of the compressor 201 is increased, the drive current of the compressor 201 can be increased.
For example, in the present embodiment, when the temperature of the air discharged from the indoor unit 100 is to be increased when the air conditioner 10 operates in the heating operation, the indoor unit 100 may transmit the operation information based on the temperature increase request to the outdoor unit communication unit 211 of the outdoor unit 200.
In this way, the outdoor unit communication unit 211 can transmit the operation information based on the request for temperature increase of the discharged air to the outdoor unit control unit 212, and the outdoor unit control unit 212 can transmit the operation frequency corresponding to the received operation information to the compressor driving unit 213.
The compressor driving part 213 may generate a driving current corresponding to the received operating frequency and transmit the generated driving current to the compressor 201, and the compressor 201 may be driven by the transmitted driving current.
For example, in the indoor unit 100, the driving current can be increased to increase the temperature of the discharged air by increasing the operating frequency of the compressor 201, and conversely, the driving current can be decreased to decrease the temperature of the discharged air by decreasing the operating frequency of the compressor 201.
In this embodiment, when the outdoor unit controller 212 receives a request for reducing the drive current generated by the compressor driver 213 from the indoor unit controller 143, the drive current can be reduced by reducing the operating frequency of the compressor 201.
If the reduction in the drive current is a current for performing the humidification operation described later, the outdoor unit control unit 212 may set the reduction amount of the drive current in advance. For example, the user can set the reduction amount of the drive current for performing the humidification operation in advance by the indoor unit operation unit 146 of the indoor unit 100 or the outdoor unit operation unit 216 of the outdoor unit 200.
In this embodiment, the reduction amount of the driving current may be determined such that the sum of the first current consumed in the heating operation and the second current consumed in the humidifying operation is less than the maximum allowable current of the circuit breaker.
Preferably, the amount of reduction in the drive current may be determined in advance in consideration of the characteristics of the voltage input to the place where the air conditioner 10 is used, for example, a special situation such as an unstable input voltage. For example, the amount of reduction in the drive current may be determined such that the sum of the first current and the second current is smaller than a value obtained by adding a margin to the maximum allowable current of the circuit breaker (maximum allowable current — margin). The margin may be set to a range of 0.5% to 2% of the maximum allowable current.

In the present embodiment, the indoor unit 100 of the air conditioner 10 may include: a case unit 120 having an opening formed in a front surface thereof and a suction port formed in a rear surface thereof; and a door unit 130 assembled to cover the front surface of the case unit 120. The combination of the casing unit 120 and the door unit 130 can form the overall appearance of the indoor unit 100.
A front discharge port 111 may be formed in the front of the door unit 130, and side discharge ports 121 may be formed in the left and right sides of the case unit 120.
The air can be discharged from the inside of the indoor unit 100 into the room through the front discharge port 111 and/or the side discharge port 121.
Although not shown, various components for performing various inherent functions and additional functions may be provided in the inner space of the indoor unit 100.
A door 112 may be provided at the front discharge opening 111. The door 112 is openable and closable, and can shield and open and close the front discharge port 111.
A discharge grid 122 is disposed inside a position corresponding to the front discharge port 111. The discharge grill 122 may protrude from the inside toward the outside of the front discharge port 111. Preferably, the ejection grill 122 projects forward from the front surface of the door unit 130.
The discharge grill 122 is located inside the front discharge port 111 when the air conditioner 10 is in a stopped or standby state, and moves and projects toward the outside of the front discharge port 111 when the air conditioner 10 is operating.
The discharge grid 122 is moved again into the front discharge opening 111 and returned by a specific signal in a state of being projected to the outside of the front discharge opening 111.
The discharge grill 122 is adjusted in its turning angle so as to turn in the vertical and horizontal directions in a state of protruding outward from the front discharge port 111. The steering angle and the steering direction of the discharge grill 122 are not limited to a specific angle or a specific direction.
This adjustment of the steering angle can also be immediately converted from a first specific direction into an arbitrary second specific direction.
The indoor unit 100 may include: a camera 113 for taking an indoor image on an upper side of the indoor unit 100; and a display 114 for visually displaying the operation information of the indoor unit 100. The user can visually confirm the motion information displayed in the display 114.
The indoor unit 100 of the present embodiment may include a humidifying assembly 300. The humidifying unit 300 may be disposed at any position, but in the present embodiment, it is preferably disposed at a lower portion of the indoor unit 100.
The humidifying assembly 300 generates steam for the indoor unit 100 to perform a humidifying operation, and generates humidified air by mixing the generated steam and filtered air, and the generated humidified air may be injected toward the room through an independent flow path, thereby providing humidified air toward the room. The humidified air can be discharged into the room by a fan (not shown) provided inside the indoor unit 100.
The humidifying unit 300 can be selectively operated based on a control signal of the indoor unit controller 143.
The humidifying assembly 300 according to the present embodiment may include: a water tank 310 for storing water; and a steam generator 311 that receives the water stored in the water tank 310 and stores the water therein, and converts the water stored therein into steam by a heater (not shown) that generates heat by applying power, thereby generating humidified air.
The humidifying assembly 300 is surrounded by the inner case 301, and the steam generated from the humidifying assembly 300 can directly flow to the side discharge port 121 via the steam guide 312.
The door unit 130 is slidable in the left-right direction with respect to the case unit 120. A part or the whole of the inside of the humidifying assembly 300 can be opened by the sliding of the door unit 130.
By such opening, the water tank 310 is exposed to the outside, and the water tank 310 is not exposed to the outside when the door unit 130 is not opened.
In the present embodiment, the opening and closing of the door unit 130 is divided into two stages.
The first stage opening and closing of the door unit 130 is a case where only a part thereof is opened, and is for supplying water to the humidifying assembly 300. In the first stage opening and closing, only an area exposing only the water tank 310 of the humidifying assembly 300 is opened.
The second stage opening and closing of the door unit 130 is the case where the opening is the maximum, and is for installation and repair. In the second stage of opening and closing, the humidifying module 300 is completely exposed.
In order to perform the two-stage opening and closing as described above, the door unit 130 of the present embodiment may include a door stopper structure (not shown) for restricting the two-stage opening and closing.
Fig. 8 is a diagram for explaining the flow of signals based on the operation of the humidifying unit in the indoor unit of the air conditioner according to the embodiment of the present invention.
Referring to fig. 8, the indoor unit 100 may include: an indoor unit communication unit 141 that performs wired or wireless communication with the outdoor unit 200; an input unit 142 that receives instructions and information based on user operations; an indoor unit control unit 143 for controlling the overall operation of the indoor unit 100; a humidifying-component driving unit 144 that controls driving of the humidifying component 300; and a blower fan driving unit 145 for controlling the driving of the blower fan 101 a. Alternatively, the indoor unit 100 may further include an indoor unit operation unit 146, and the indoor unit operation unit 146 may be configured to receive an operation command for the indoor unit 100 from a user.
The indoor unit communication unit 141 can perform wired or wireless communication with the outdoor unit communication unit 211. The indoor unit communication unit 141 may perform wired or wireless communication with a remote control device (not shown).
The input unit 142 receives commands and information necessary for operating the air conditioner 10. The user can input commands such as temperature, operation mode, and timer through the input unit 142 and set them. For example, the input section 142 may be implemented by a touch panel.
The indoor unit controller 143 can perform the operation of the indoor unit 100 according to the input operation mode. In particular, when a humidification operation request is input through the input unit 142, the indoor unit control unit 143 of the present embodiment performs humidification operation through communication with the outdoor unit 200.
Therefore, when a humidification operation request is input, the indoor unit controller 143 may output a control signal for performing the humidification operation to the humidification module driver 144, and the humidification module driver 144 may drive the humidification module 300 according to the received control signal.
The control signal may include information required in performing the humidification operation. For example, information on the set indoor humidity, humidification amount, humidification time, and the like may be included.
In this embodiment, the indoor unit 100 may perform the humidification operation during the heating operation. When a humidification operation request is input during the heating operation, the indoor unit controller 143 outputs a control signal to the humidification module driver 144 to perform the humidification operation independently of the heating operation, and thus drives the humidification module 300.
The indoor unit control unit 143 can drive the blower fan 101a by controlling the blower fan drive unit 145 as necessary.
Fig. 9 is a flowchart for explaining a humidification operation method of an air conditioner according to an embodiment of the present invention.
Referring to fig. 9, when a humidification operation request for the indoor unit 100 is input through the input unit 142 (S103) while the air conditioner 10 of the present embodiment is operating in the heating operation (S101), the indoor unit control unit 143 transmits humidification operation information for performing the humidification operation to the outdoor unit control unit 212 (S105).
When the outdoor unit control unit 212 receives the humidification operation information, the outdoor unit control unit 212 transmits a control signal for reducing the drive current of the compressor 201 to the compressor drive unit 213 (S107). The drive current is the drive current of the compressor 201 required for the heating operation currently in operation.
The compressor driving unit 213 reduces the driving current according to the control signal (S109).
In the present embodiment, the drive current can be reduced by reducing the operating frequency of the compressor 201.
In this case, when the outdoor unit controller 212 receives the humidification operation information from the indoor unit controller 143, the outdoor unit controller 212 may transmit a control signal for reducing the operation frequency of the compressor 201 to the compressor driver 213. The compressor driving unit 213 can reduce the driving current by reducing the operating frequency of the compressor 201.
When the outdoor unit control unit 212 confirms the decrease in the drive current, it notifies the indoor unit control unit 143 of the decrease in the drive current (S111). Since it takes time to reduce the drive current, it is necessary to confirm whether the drive current is actually reduced by a predetermined amount.
When the indoor unit control unit 143 receives the notification of the decrease in the drive current, the indoor unit control unit 143 operates the humidification module drive unit 144 (S113), thereby operating the humidification module 300 (S115). Accordingly, the humidifying operation can be performed by the operation of the humidifying unit 300 (S117).
On the other hand, after the driving current is reduced in step S109, a step of determining whether the driving current is reduced to a preset current value may be further included.
This is to start the humidification operation after confirming that the drive current has indeed decreased to the predetermined value or less. If the humidifying operation is started in a state where the drive current is not reduced to a preset current value, the circuit breaker operates in a state where the maximum allowable current of the circuit breaker may be exceeded, as in the prior art.
As described above, in the present embodiment, when a humidification operation request is input while the heating operation is being performed in the indoor unit, the humidification operation is performed after the drive current of the compressor in the outdoor unit is reduced.
In this case, the magnitude of the reduced drive current may correspond to the magnitude of the current required by the motor when the humidification operation is performed. That is, a part of the driving current required for the heating operation is reduced, and a part corresponding to the reduced driving current is used as the current required for the humidification operation. Such a reduction in drive current can be achieved by reducing the operating frequency of the compressor.
Fig. 10 is a flowchart for explaining a humidification operation method of an air conditioner according to another embodiment of the present invention.
Referring to fig. 10, in the air-conditioning apparatus 10 of the present embodiment, it is determined whether or not a humidification operation request is input to the indoor unit 100 via the input unit 142 (S201).
When the humidification operation request is input, the indoor-unit controller 143 determines whether or not the operation is currently performed in the heating operation (S203).
When the air-warming operation is currently performed, the indoor-unit controller 143 transmits the humidification operation information to the outdoor-unit controller 212 (S205).
When the outdoor unit control unit 212 receives the humidification operation information, the outdoor unit control unit 212 transmits a control signal for reducing the drive current to the compressor drive unit 213 (S207).
The compressor driving part 213 reduces the driving current according to the control signal (S209). By reducing the operating frequency of the compressor 201, the drive current can be reduced.
When the outdoor unit control unit 212 confirms the decrease in the drive current, the outdoor unit control unit 212 notifies the indoor unit control unit 143 of the decrease in the drive current (S211).
When the indoor unit control unit 143 receives the notification of the decrease in the drive current, the indoor unit control unit 143 operates the humidification module drive unit 144 (S213) and operates the humidification module 300 (S215), thereby performing the humidification operation (S217).
If, in step S203, the indoor unit 143 is not currently operating in the heating operation, the indoor unit 143 operates the humidification module 300 (S215) by operating the humidification module drive unit 144 (S213), thereby performing the humidification operation (S217).
When the humidification operation is started, the indoor unit controller 143 may notify the outdoor unit controller 212 that the humidification operation has been started.
As described above, in the present embodiment, when a humidification operation request is input from the indoor unit, it is checked whether or not the heating operation is being performed, and then, when the heating operation is being performed, the drive current of the compressor in the outdoor unit is reduced, and the humidification operation is performed. If the heating operation is not performed, the humidification operation can be performed without reducing the drive current of the compressor. The reduced magnitude of the driving current may correspond to the magnitude of the current required by the motor when performing the humidification operation.
Fig. 11 is a flowchart showing the flow of signals between the indoor unit and the outdoor unit in the humidification operation method for the air conditioner according to the embodiment of the present invention.
In the air conditioner 10 of the present embodiment, when the heating operation is input (S301), the indoor unit control unit 143 transmits the input heating operation information to the outdoor unit control unit 212 (S303).
The outdoor unit control unit 212 drives the compressor 201 to perform the heating operation (S305). The compressor 201 can be driven by the compressor driving unit 213 by transmitting a control signal from the outdoor unit control unit 212 to the compressor driving unit 213.
When the compressor 201 is driven, the indoor unit 100 starts the heating operation, and the outdoor unit control unit 212 transmits heating operation start information including information indicating that the compressor 201 for performing the heating operation is driven to the indoor unit control unit 143 (S307). The indoor unit 100 operates in a heating operation.
The heating operation start information may include information on a driving current of the compressor 301 and information on an operating frequency for driving the compressor 201.
When a request for the humidification operation is input during the heating operation (S309), the indoor unit control unit 143 notifies the humidification module driving unit 144 that the humidification operation request is input (S311).
The humidification module drive unit 144 prepares for the humidification operation (S313), and transmits the humidification operation preparation completion to the indoor unit control unit 143 (S315).
When receiving the end of the humidification operation preparation, the indoor unit control unit 143 requests the outdoor unit control unit 212 to decrease the drive current of the compressor 201 (S317). Such a drive current reduction request may include a reduction request of the operating frequency of the compressor 201.
The outdoor unit control unit 212 reduces the drive current of the compressor 201 for performing the heating operation currently being performed, in response to the drive current reduction request (S319). Such a reduction in the driving current can be achieved by reducing the operating frequency of the compressor 201.
As described above, in the case of reducing the drive current for performing the humidification operation, the reduction of the drive current may be set in advance.
In the present embodiment, as described above, the reduction amount of the driving current may be determined such that the sum of the first current required in the heating operation and the second current required in the humidifying operation currently being performed is less than the maximum allowable current of the circuit breaker.
When the driving current decreases, the outdoor unit controller 212 notifies the indoor unit controller 143 of the decrease in the driving current (S321).
After confirming the decrease in the drive current of the compressor 201 (S323), the indoor-unit controller 143 requests the humidification-module driver 144 to drive the humidification module 300 (S325).
The humidification-module driving unit 144 operates the humidification module 300 in response to the request (S327). By the operation of the humidifying unit 300, a heater (not shown) for performing the humidifying operation is operated.
After that, the humidification module drive unit 144 notifies the indoor unit control unit 143 of the start of the humidification operation (S329). Thus, the indoor unit controller 143 can confirm that the current operation state is the heating operation and the humidification operation, and display the operation state on the display.
Fig. 12 is a flowchart for explaining a humidification operation method of an air conditioner according to still another embodiment of the present invention.
Referring to fig. 12, in the present embodiment, when a request for stopping the humidification operation of the indoor unit 100 is input through the input unit 142 (S401), the indoor unit control unit 143 transmits a control signal to the humidification module driving unit 144 to stop the humidification operation (S403), and thereby stops the operation of the humidification module 300 (S405).
When the humidification module 300 stops operating, the humidification module drive unit 144 transmits the operation stop to the indoor unit controller 143 (S407).
After that, the indoor unit controller 143 determines whether the current heating operation is being performed (S409).
If the heating operation is being performed, the indoor-unit controller 143 transmits the humidification operation stop to the outdoor-unit controller 212 (411).
The outdoor unit control unit 212 transmits a control signal to the compressor driving unit 213 in order to increase the driving current of the compressor 201 (S413).
The compressor driving unit 213 increases the driving current of the compressor 201 according to the control signal (S415). Such an increase in the drive current preferably corresponds to the current required in the previous humidification operation.
After the drive current is increased, the current consumed in the air conditioner 10 is made smaller than the maximum allowable current of the circuit breaker. The amount of increase in the drive current may be set in advance. For example, the increase amount of the driving current may be set in advance such that the sum of the first current required for the heating operation and the increased driving current is less than the maximum allowable current of the circuit breaker.
On the other hand, the increase in the driving current can be achieved by increasing the operating frequency of the compressor 201.
The compressor driving unit 213 increases the driving current by increasing the operating frequency, and then notifies the outdoor unit control unit 212 of the increase in the driving current (S417). Thus, the heating operation can be continued by the increased drive current.
When receiving the increase in the driving current, the outdoor unit controller 212 transmits the result to the indoor unit controller 143 (S419). The indoor-unit controller 143 continues the operation in the heating operation (S421).
The indoor unit controller 143 may display information on the stop of the humidification operation and the heating operation on the display so that the user can confirm the current operation state.
As described above, in the present embodiment, when the humidification operation is stopped while the humidification operation is being performed, if the heating operation is simultaneously performed in the indoor units, the heating operation can be continuously performed by increasing the driving current of the compressor in the outdoor unit.
At this time, the magnitude of the increased driving current may correspond to the magnitude of the current required by the motor when the humidification operation is performed. That is, since the humidification operation is stopped, the current used in the humidification operation is no longer necessary, and a portion corresponding to the magnitude of the current used in the humidification operation is used as the current required for the heating operation. Such an increase in the drive current can be achieved by increasing the operating frequency of the compressor.
Fig. 13 is a flowchart for explaining a humidification operation method of an air conditioner according to still another embodiment of the present invention.
Referring to fig. 13, in the present embodiment, when a heating operation request is input (S503) while the indoor unit 100 is operating in the humidification operation (S501), the indoor unit controller 143 transmits the input of the heating operation request to the outdoor unit controller 212 (S505).
The outdoor unit control unit 212 outputs a control signal for reducing the drive current to the compressor drive unit 213 (S507), and the compressor drive unit 213 generates the reduced drive current based on the control signal and operates the compressor 201 (S509).
When the compressor 201 operates, the compressor driving unit 213 notifies the outdoor unit control unit 212 of the operation of the compressor (S511), and the outdoor unit control unit 212 transmits the operation of the compressor to the indoor unit control unit 143 again (S513).
As described above, the reason for reducing the drive current is that the indoor unit 100 already performs the humidification operation, and therefore, the current required for the humidification operation is consumed, and if the drive current required for the heating operation is added, the circuit breaker may be operated.
Therefore, during the humidification operation, the compressor 201 is driven with a drive current smaller than that required in the previous heating operation.
As described above, in the present embodiment, when a heating operation request is input while the indoor unit is performing the humidification operation, the compressor is driven with the drive current of the compressor in the outdoor unit reduced, and then the heating operation is performed. The reduction in the drive current may correspond to the current required by the motor when the humidifying operation is performed.
Fig. 14 is a flowchart for explaining a humidification operation method of an air conditioner according to still another embodiment of the present invention.
Referring to fig. 14, when a heating operation and a humidification operation request are input to the indoor unit (S601), the indoor unit controller 143 transmits the heating operation and the humidification operation request to the outdoor unit controller 212 (S603).
As an example of the input in step S601, a case may be mentioned in which the heating operation and the humidification operation are simultaneously input when the indoor unit is in a standby state, and as another example, the heating operation and the humidification operation are input at short time intervals (for example, 1 to 2 seconds) when the indoor unit is in a standby state.
Step S601 of this embodiment may include: although a request for any operation is input, a request for another operation may be input before the operation is started.
When the requests for the two operations are input simultaneously or continuously, the two operations may be executed simultaneously or sequentially and immediately.
The outdoor unit control unit 212 outputs a control signal for reducing the drive current to the compressor drive unit 213 (S605), and the compressor drive unit 213 generates the reduced drive current based on the control signal and drives the compressor 201 (S607).
When the compressor 201 is operated, the compressor driving unit 213 notifies the outdoor unit control unit 212 of the operation of the compressor (S609), and the outdoor unit control unit 212 transmits the operation of the compressor to the indoor unit control unit 143 again (S611).
The indoor unit controller 143 operates the humidification module 300 by operating the humidification module driver 144 (S613) (S615), and starts the humidification operation (S617). As the humidification operation is started, it may be performed simultaneously with the heating operation being performed.
As described above, the reason for reducing the drive current is that the indoor unit 100 is performing the humidification operation, and therefore, the current required for the humidification operation is consumed, and if the drive current required for the heating operation is additionally added, the circuit breaker may be operated.
Therefore, when the heating operation and the humidification operation are simultaneously performed, the driving current consumed in the heating operation is reduced in order to secure the current required for the humidification operation.
As described above, in the present embodiment, when the heating operation and the humidification operation are simultaneously performed in the indoor unit, the compressor is driven in a state where the driving current of the compressor in the outdoor unit is reduced, and then the heating operation and the humidification operation can be simultaneously performed. The reduction in the drive current may correspond to the current required by the motor when the humidifying operation is performed.
Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the above-described embodiments, and may be manufactured in various forms different from each other, and a person skilled in the art can understand that the present invention may be implemented in other embodiments without changing the technical idea or essential features of the present invention. The embodiments described above are therefore to be understood as illustrative in all respects and not restrictive.
