For example, the communication unit 160 may exchange data with the indoor unit 300 through wired communication, or may exchange data with the indoor unit 300 through wireless communication such as Zigbee, Wi-Fi, and Bluetooth communication.

Meanwhile, the communication unit 160 may receive current temperature information, set target temperature information, current humidity information, operation state information, and the like from the indoor unit 300.

The input unit 120 may include a plurality of buttons or a touch screen attached to the remote control 100. It is possible to turn on the power of the remote control 100 and operate the remote control 100 through a plurality of buttons or a touch screen.

The controller 140 may transmit a control command received through the input unit 120 to the indoor unit 300 or the outdoor unit 200.

In addition, the controller 140 may control the display 110 to display temperature information, set target temperature information, current humidity information, operation state information, and the like, received through the communication unit 520.

In addition, the controller 140 may store temperature information, set target temperature information, current humidity information, operation state information, etc. received through the communication unit 520 in the memory 170.

Meanwhile, the memory 170 may store various data for overall operation of the remote control 100, such as a program for processing or controlling the controller 140.

In addition, the memory 170 may store information on a gap, which is a reference for outputting a contact signal.

Meanwhile, the sensing unit 130 may include a temperature sensor that senses the current indoor temperature.

Meanwhile, the remote control 100 may include a power supply unit (not shown), and the power supply unit (not shown) may supply power required for operation of each component under the control of the controller 140.

Specifically, the interface unit 150 may include an analog signal output port for outputting a proportional control signal and a digital signal output port 151 for outputting an on/off signal.

In this case, the controller 140 may output a contact signal for on/off of an external device through the digital signal output port 151.

Specifically, 0 (off), which is the value of the digital signal output port 151, means open and 1 (on) means short, and serves to turn on/off the contact point of the external device 500. Can be done.

The digital signal output port 151 is connected to the contact input terminal of the contact controller 510 of the external device 500, and when a contact signal for on/off of the external device is output through the digital signal output port 151, the The contact signal may be input to the contact controller 510 of the external device 500.

4 is a diagram illustrating a method of operating a remote controller for controlling an air conditioning system according to an embodiment of the present invention.

According to FIG. 4, the controller 140 may receive error information from the air conditioning system (S410).

Specifically, the outdoor unit 200 or the indoor unit 300 may transmit error information of the air conditioning system to the remote control 100 when the air conditioning system is unable to operate due to a failure or the like.

And, when the error information is received through the communication unit 160, the controller 140 may obtain information on the target temperature of the air conditioning system (S420).

Specifically, when an input for setting a target temperature of the air conditioning system is received from the remote control 100, the controller 140 may store information on the target temperature in the memory 170.

In addition, when an input for setting the target temperature of the air conditioning system is received by another device such as the wireless remote control 400, the controller 140 adjusts the target temperature of the air conditioning system from the wireless remote control 400 or the indoor unit 300. Information about the information may be received and stored in the memory 170.

In addition, when error information is received through the communication unit 160, the controller 140 may read information on the target temperature of the air conditioning system from the memory 170.

Meanwhile, the controller 140 may obtain information on the current indoor temperature (S430).

Specifically, when the sensing unit 130 is installed in the remote control 100, the sensing unit 130 may sense the room temperature and transmit it to the controller 140.

As another example, the controller 140 may receive information on the current indoor temperature from another device.

Specifically, a temperature sensor is installed in the indoor unit 300 or the wireless remote control 400 to detect the current indoor temperature. In this case, the controller 140 may receive information on the current indoor temperature from the indoor unit 300 or the wireless remote control 400.

Meanwhile, even in a state in which the air conditioning operation of the air conditioning system is impossible, the indoor unit 300 may detect the temperature in some cases. That is, even after receiving error information from the indoor unit 300, the controller 140 may receive information on the current indoor temperature from the indoor unit 300.

Meanwhile, the controller 140 may determine an external device having an attribute corresponding to an operation mode of the air conditioning system (S440).

Specifically, first, the controller 140 may determine an operation mode of the air conditioning system.

For example, when cooling is being performed because the current indoor temperature is higher than the target temperature, the controller 140 may determine that the operation mode of the air conditioning system is the cooling mode.

For another example, when heating is being performed because the current indoor temperature is lower than the target temperature, the controller 140 may determine that the operation mode of the air conditioning system is the heating mode.

In addition, the controller 140 may determine the cooling/heating properties of the external devices 500 and 600.

In more detail, information on the properties of the external devices 500 and 600 may be input to the remote control 100 and stored in the memory 170 together with information on the digital output port to which the external devices 500 and 600 are connected.

For example, when the first external device 500 is a cooler that performs cooling, the first external device 500 may have cooling properties.

For another example, when the second external device 600 is an electric heater that performs heating, the second external device 600 may have heating properties.

In this case, the controller 140 may store information indicating that the property of the first external device 500 is cooling, and that the remote control 100 and the first external device 500 are connected through the first digital output port.

In addition, the controller 140 may store information indicating that the property of the second external device 600 is heating, and that the remote control 100 and the second external device 600 are connected through a second digital output port.

Meanwhile, the controller 140 may output a contact signal for turning on the external device based on the operation mode of the air conditioner and the cooling/heating property of the external device.

Specifically, when the operating mode of the air conditioning system is a cooling mode, the controller 140 may output a contact signal for turning on an external device having a cooling property. That is, the controller 140 may output a contact signal for turning on an external device through the first digital output port.

In addition, when the operating mode of the air conditioning system is a heating mode, the controller 140 may output a contact signal for turning on an external device having a heating property. That is, the controller 140 may output a contact signal for turning on the external device through the second digital output port.

Meanwhile, the controller 140 may output a contact signal for turning on an external device based on a difference between the target temperature of the air conditioning system and the current indoor temperature.

In this case, if the difference between the target temperature and the indoor temperature is greater than the first reference gap, the controller 140 may output a contact signal for turning on the external device (S450).

Specifically, the cooling/heating performance of the external device is generally inferior to the cooling/heating performance of the air conditioning system, and the external device plays a role of supplementing the cooling/heating function of the air conditioning system.

Therefore, in a situation in which the air conditioning system cannot operate due to a failure or the like, it may be impossible to control the temperature to the target temperature of the air conditioning system only with an external device, or even if it is possible, the efficiency may be very low.

Therefore, when the difference between the target temperature and the indoor temperature is greater than the first reference gap, the controller 140 may output a contact signal for turning on the external device.

For example of cooling, if the target temperature of the air conditioning system is 24 degrees and the current room temperature is 28 degrees, and the first reference gap is 2 degrees, the difference between the target temperature of 24 degrees and the current room temperature of 28 degrees is the first standard. Because it is larger than the gap, the controller 140 may output a contact signal for turning on the first external device 500.

As another example of cooling, if the target temperature of the air conditioning system is 24 degrees, the current room temperature is 25 degrees, and the first reference gap is 2 degrees, the difference between the target temperature of 24 degrees and the current indoor temperature is 25 degrees. Since it is smaller than the reference gap, the controller 140 may not output a contact signal for turning on the first external device 500.

In addition, for heating, if the target temperature of the air conditioning system is 28 degrees, the current indoor temperature is 22 degrees, and the first reference gap is 3 degrees, the difference between the target temperature of 28 degrees and the current indoor temperature of 22 degrees is the first. Since it is larger than the reference gap, the controller 140 may output a contact signal for turning on the second external device 600.

As another example of heating, if the target temperature of the air conditioning system is 28 degrees, the current room temperature is 26 degrees, and the first reference gap is 3 degrees, the difference between the target temperature of 28 degrees and the current room temperature is 26 degrees. Since it is smaller than the reference gap, the controller 140 may not output a contact signal for turning on the first external device 500.

Meanwhile, the first reference gap may be different according to the type of external device.

Specifically, cooling performance or heating performance may be different depending on the type of external device. Therefore, the first reference gap may be different according to the type of external device.

For example, when the heating performance of the boiler is better than that of the electric heater, the first reference gap when the external device is a boiler may be smaller than the first reference gap when the external device is an electric heater. have.

In addition, the first reference gap may be different according to the target temperature of the air conditioning system.

Specifically, when the target temperature is 29 degrees and the external device is an electric heater, it may be impossible to raise the indoor temperature to 29 degrees with the electric heater. On the other hand, if the target temperature is 25 degrees and the external device is an electric heater, it may be possible to raise the indoor temperature to 25 degrees by using an electric heater.

Accordingly, in the cooling mode, as the target temperature decreases, the first reference gap may increase, and as the target temperature increases, the first reference gap may decrease.

For example, when the target temperature of the air conditioning system is 24 degrees, the first reference gap may be 2 degrees. In this case, when the current temperature is higher than 26 degrees, the controller 140 may output a contact signal for turning on the external device.

For another example, when the target temperature of the air conditioning system is 20 degrees, the first reference gap may be 5 degrees. In this case, the controller 140 may output a contact signal for turning on an external device when the current temperature is higher than 25 degrees Celsius.

According to the same principle, in the heating mode, as the target temperature increases, the first reference gap may increase, and as the target temperature decreases, the first reference gap may decrease.

Also, the first reference gap may be set by user input.

Meanwhile, when a contact signal for turning on the external device is output, the contact controller of the external device may turn on the external device. In this case, the external device may perform a cooling or heating function according to a preset control logic. In this case, the external device can perform maximum cooling or maximum heating.

Meanwhile, after outputting a contact signal for turning on the external device, the controller 140 may output a contact signal for turning off the external device based on a difference between the target temperature of the air conditioning system and the current indoor temperature.

In this case, when the difference between the target temperature and the indoor temperature is less than the first reference gap, the controller 140 may output a contact signal for turning off the external device (S460).

Specifically, the first reference gap is determined according to the target temperature, the type of external device, and user input, and when the current temperature reaches the temperature reflecting the first reference gap, the target of the external device itself has been achieved. I can.

Therefore, when the difference between the target temperature and the current temperature is smaller than the first reference gap, the controller 140 may output a contact signal for turning off the external device.

For example of cooling, when the target temperature of the air conditioning system is 24 degrees and the first reference gap is 2 degrees, the controller 140 generates a contact signal for turning off the external device when the current temperature is lower than 26 degrees. Can be printed.

In addition, for example of heating, when the target temperature of the air conditioning system is 28 degrees and the first reference gap is 3 degrees, the controller 140 is a contact signal for turning off the external device when the current temperature is higher than 25 degrees. Can be printed.

Meanwhile, S450 and S460 may be repeated. For example, if the difference between the target temperature and the current temperature becomes larger than the first reference gap after the contact signal for turning off the external device is output, the controller 140 is again a contact signal for turning the external device on. Can be printed.

Meanwhile, it has been described that both the output of the contact signal for ON of the external device and the output of the contact signal for off of the external device are determined according to the first reference gap, but are not limited thereto.

Specifically, when the difference between the target temperature and the current temperature is greater than the first reference gap, the controller 140 outputs a contact signal for turning on the external device, and when the difference between the target temperature and the current temperature is less than the second reference gap, the controller 140 A contact signal for turning off the device can be output. In addition, the second reference gap may be smaller than the first reference gap.

For example of cooling, when the target temperature of the air conditioning system is 24 degrees, the first reference gap is 2 degrees, and the second reference gap is 1 degree, the controller 140 is the current room temperature is 26 degrees. If it is higher than degrees, a contact signal for turning on the first external device 500 may be output, and if the current indoor temperature is lower than 25 degrees, a contact signal for turning off the first external device 500 may be output.

That is, according to the present invention, the operation margin is secured by making the first reference gap and the second reference gap different from each other, thereby preventing excessive repetition of the on/off operation.

In addition, when the error cancellation information of the air conditioning system is received through the communication unit, the controller 140 may output a contact signal for turning off the external device.

In more detail, the outdoor unit 200 or the indoor unit 300 may transmit error cancellation information to the remote control 100 when a malfunction of the air conditioning system is resolved and operation is possible (or when operation is started again).

In this case, it is possible to refrigerate or heat without operating an external device. Therefore, when the error cancellation information is received, the controller 140 may output a contact signal for turning off the external device.

Meanwhile, in the above-described embodiment, it has been described that the difference between the target temperature of the air conditioning system and the current indoor temperature is compared with a reference gap and a contact signal for on/off of an external device is output, but is not limited thereto.

Specifically, the controller 140 may compare the target temperature of the air conditioning system with the current indoor temperature and output a contact signal for on/off of the external device.

For example, when the target temperature of the air conditioning system is 24 degrees and the operation mode is the cooling mode, the controller 140 outputs a contact signal for turning on the first external device 500 when the current temperature is higher than 24 degrees, When the current temperature is lower than 24 degrees, a contact signal for turning off the first external device 500 may be output.

In addition, in the above-described embodiment, it has been described that a contact signal for on/off of an external device is output by using a target temperature of the air conditioning system, but is not limited thereto.

Specifically, the controller 140 may output a contact signal for on/off of the external device by comparing the target temperature and the current temperature of the external device.

For example, if the external device is a boiler and the target temperature of the boiler is 28 degrees, the controller 140 outputs a contact signal for turning on the boiler if the current temperature is lower than 28 degrees, and if the current temperature is higher than 28 degrees, Contact signal for off can be output.

Meanwhile, in the above-described embodiment, when error information of the air conditioning system is received, it has been described that a contact signal for turning on an external device is output (S410).

However, the present invention is not limited thereto, and S410 may be omitted.

That is, the controller 140 may output a contact signal for on/off of an external device through the digital output port based on the target temperature and the current temperature of the air conditioning system, regardless of whether error information is received.

Specifically, operating together with an air conditioning system up to an external device performing a cooling/heating function may increase a cooling or heating speed rather than operating only the air conditioning system alone.

Accordingly, even while the air conditioning system is operating normally, the controller 140 may output a contact signal for on/off of the external device based on the target temperature and the current temperature of the air conditioning system through the digital output port.

Meanwhile, in order for the wired remote control 100 to transmit and receive temperature information, operation state information, and control commands while communicating with the indoor unit 300 or the outdoor unit 200, a communication channel and a communication module are required.

However, in the present invention, by controlling on/off of an external device by outputting a contact signal through a digital signal output port, the cost and effort to separately provide a communication channel and a communication module for communication with the external device can be saved. There is an advantage.

In addition, since the contact output method is used, there is an advantage of being able to perform on/off control by being connected to various products such as a cooler, boiler, and electric heater without separate configuration of a communication channel and a communication module.

Meanwhile, in FIG. 5, the temperature change over time is shown as a graph.

Upon failure of the air conditioning system (S), the room temperature 510 may change rapidly and cause discomfort to the user. However, the present invention has an advantage of minimizing temperature change by maintaining the indoor temperature 520 using an external device as an auxiliary heat source even when the air conditioning system fails.

In addition, the present invention does not operate by applying the target temperature (A) of the air conditioner to the external device as it is, but by using a value reflecting the gap (GAP) in the target temperature (A) as the target temperature (B) of the external device. Operate.

In other words, since the cooling/heating performance of the external device is generally lower than the cooling/heating performance of the air conditioning system, the target temperature of the air conditioner cannot be achieved with the operation of the external device, or the efficiency is very low even if it is achieved. Can occur. However, the present invention has an advantage of reducing the operation standard of the external device rather than the operation standard of the air conditioning system, thereby reflecting the operation limit of the external device and preventing inefficient operation.

In addition, the present invention has the advantage of accurately reflecting the operating limit of the external device and preventing inefficient operation by determining the gap by reflecting the product characteristics and target temperature.

The present invention described above can be implemented as a computer-readable code in a medium on which a program is recorded. The computer-readable medium includes all types of recording devices storing data that can be read by a computer system. Examples of computer-readable media include HDD (Hard Disk Drive), SSD (Solid State Disk), SDD (Silicon Disk Drive), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. There is this. The above detailed description should not be construed as restrictive in all respects, but should be considered as illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
