By adopting the embodiment, negative voltage of-3V to-12V can effectively provide electrons required by cation neutralization, and the electricity safety is ensured. For example, the power conversion circuit converts the input ac or dc power into-3V to-12V, and applies the converted ac or dc power to the indoor heat exchanger.

In this embodiment, the method further includes: step 11, acquiring the running state of the air conditioner; and 12, controlling the negative voltage applied to the indoor heat exchanger pipeline according to the running state of the air conditioner. Optionally, the method comprises: and controlling the negative voltage applied to the indoor heat exchanger pipeline to be switched on or off according to the running state of the air conditioner. Optionally, the method comprises: and controlling the on or off of the negative voltage applied to the indoor heat exchanger pipeline and the magnitude of the negative voltage according to the running state of the air conditioner. By adopting the embodiment, the negative voltage applied to the indoor heat exchanger pipeline is controlled according to the running state of the air conditioner, so that the electric energy consumed by corrosion prevention of the air conditioner can be saved, and the energy consumption of the air conditioner is reduced.
For example, the controller of the air conditioner acquires the operating state of the air conditioner through a query mode, and controls the power conversion circuit to be turned on or off according to the operating state of the air conditioner, or controls the power conversion circuit to output negative voltage.
Optionally, the method further comprises: and when the air conditioner operates in a cooling state or a dehumidifying state, controlling the negative voltage applied to the indoor heat exchanger pipeline to be a first voltage value. Optionally, the first voltage value is-3 to-12V. By adopting the embodiment, when the air conditioner runs in a refrigerating state or a dehumidifying state, the indoor heat exchanger pipeline is in a humid environment or even in an environment with moisture, so that the negative voltage applied to the indoor heat exchanger pipeline is controlled to be the first voltage value by the method, enough negative charges can be provided for the indoor heat exchanger pipeline, and the indoor heat exchanger pipeline is effectively protected from corrosion.
For example, the controller of the air conditioner acquires that the air conditioner operates in a cooling state or a dehumidifying state through an inquiry mode, and the controller controls the output voltage of the power conversion circuit to be-3V to-12V.
Optionally, the method further comprises: and when the air conditioner operates in a standby state, a heating state or a blowing state, the negative voltage applied to the indoor heat exchanger pipeline is turned off. By adopting the embodiment, because the indoor heat exchanger pipeline is in a dry state, each part is relatively stable, the oxidation resistance is higher, and the anticorrosion protection function does not need to be started.
For example, when the controller of the air conditioner acquires that the air conditioner operates in a standby state, a heating state or an air supply state through a query mode, the controller turns off the output voltage of the power conversion circuit.
Optionally, the method further comprises: when the air conditioner is operated in a standby state, or a heating state, or a blowing state, the negative voltage applied to the indoor heat exchanger line is turned off every fixed time interval. By adopting the embodiment, because the indoor heat exchanger pipeline is in a dry state, all the parts are relatively stable, the oxidation resistance is higher, and the anticorrosion protection function does not need to be started all the time, the negative voltage applied to the indoor heat exchanger pipeline is turned off at fixed time intervals, and the electric energy consumed by anticorrosion can be saved.
Optionally, when the air conditioner operates in a standby state, the negative voltage applied to the indoor heat exchanger pipeline is turned off every first time interval, the turn-off time is a first turn-off time, the first time interval is 0.5-1 hour, and the first turn-off time is 0.5-2 hours. When the air conditioner is in a standby state, the environment where the indoor heat exchanger pipeline is located is the indoor environment, and the air conditioner just finishes running, so that the indoor humidity value is relatively low, by adopting the embodiment, the negative voltage is started to run for 0.5-1 hour, the anti-corrosion measures in the standby state time period of the air conditioner can be ensured to be effectively started, electrons flow to the part of the indoor heat exchanger pipeline to be protected and neutralize cations in time, the indoor heat exchanger pipeline is protected from being oxidized and corroded, and a good anti-corrosion effect is realized; when the time of starting the negative voltage and running for the first time interval is up, the anti-corrosion measures are finished, the time of the first time interval can reach a better anti-corrosion effect, and the energy consumption of the anti-corrosion measures in a standby state can be saved by turning off the first turn-off time of the negative voltage.
Optionally, when the air conditioner is operated in a heating state, the negative voltage applied to the indoor heat exchanger pipeline is turned off every second time interval, the turn-off time is second turn-off time, the second time interval is 10-20 minutes, and the second turn-off time is 2-4 hours. When the air conditioner is in a heating state, the environment of the indoor heat exchanger pipeline is dry, the oxidized area of the indoor heat exchanger pipeline is small, the speed is low, by adopting the embodiment, the negative voltage is started to operate for 10-20 minutes, the anti-corrosion measure of the air conditioner in the heating state can be ensured to be effectively started, electrons flow to the part to be protected of the indoor heat exchanger pipeline and neutralize cations in time, and the indoor heat exchanger pipeline is protected from being oxidized and rusted; when the time of starting the negative voltage and operating the second time interval is up, the anti-corrosion measures are finished, a good anti-corrosion effect can be achieved, and due to the fact that the oxidized area of the indoor heat exchanger pipeline is small and the speed is low in the heating state, the negative voltage is turned off for 2-4 hours, energy consumption of the anti-corrosion measures in the heating state can be saved.
Optionally, when the air conditioner is operated in an air supply state, the negative voltage applied to the indoor heat exchanger pipeline is turned off every third time interval, the turn-off time is a third turn-off time, the third time interval is 5-10 minutes, and the third turn-off time is 2-4 hours. When the air conditioner is in an air supply state, the environment of the indoor heat exchanger pipeline is dry, the oxidized area of the indoor heat exchanger pipeline is small, the speed is low, and by adopting the embodiment, the negative voltage is started to operate for 5-10 minutes, so that the anti-corrosion measure of the air conditioner in the air supply state can be effectively started, electrons flow to the part of the indoor heat exchanger pipeline to be protected and neutralize cations in time, and the indoor heat exchanger pipeline is protected from being oxidized and rusted; when the time of starting the negative voltage and running the third time interval is up, the anti-corrosion measures are finished, a good anti-corrosion effect can be achieved, and because the oxidized area of the indoor heat exchanger pipeline in the air supply state is small and the speed is slow, the negative voltage is turned off for 2-4 hours, the energy consumption of the anti-corrosion measures in the air supply state can be saved.
Optionally, the method further comprises: when the air conditioner is operated in a standby state, or a heating state, or a blowing state, the negative voltage applied to the indoor heat exchanger line is reduced. By adopting the embodiment, when the air conditioner is in a standby state, a heating state or an air supply state, the environment of the indoor heat exchanger pipeline is dry, all the parts are relatively stable, the oxidation resistance is high, and at the moment, a corrosion protection function is not required to be provided by high negative voltage all the time, so that the negative voltage applied to the indoor heat exchanger pipeline is reduced, and the electric energy consumed by corrosion protection measures can be saved.
Optionally, the method further comprises: when the air conditioner runs in a standby state, a heating state or an air supply state, controlling the negative voltage applied to the indoor heat exchanger pipeline to be a second voltage value, wherein the second voltage value is 20% -50% of the first voltage value. With this embodiment, the electrical energy consumed for implementing the anti-corrosion measures can be saved. For example, when the air conditioner is operated in a cooling state or a dehumidifying state, the negative voltage applied to the indoor heat exchanger line is controlled to be-5V; when the air conditioner runs in a standby state, a heating state or a blowing state, the negative voltage applied to the indoor heat exchanger pipeline is controlled to be-2.5V.
Fig. 3 illustrates another alternative embodiment of a method for protecting the indoor heat exchanger tubes of an air conditioner.
In this embodiment, the method further includes: step 21, acquiring a humidity value of an environment where an indoor heat exchanger pipeline is located; and step 22, controlling the negative voltage applied to the indoor heat exchanger pipeline according to the humidity value. Optionally, the method comprises: and controlling the negative voltage applied to the indoor heat exchanger pipeline to be switched on or off according to the humidity value of the environment where the indoor heat exchanger pipeline is located. Optionally, the method comprises: and controlling the on or off of the negative voltage applied to the indoor heat exchanger pipeline and the magnitude of the negative voltage according to the humidity value of the environment where the indoor heat exchanger pipeline is located. For areas with high environmental humidity, the operating state of the air conditioner cannot be used as the basis for implementing anti-corrosion measures. By adopting the embodiment, the negative voltage applied to the indoor heat exchanger pipeline can be controlled according to the actual environment where the indoor heat exchanger pipeline is located, and the indoor heat exchanger pipeline can be effectively protected in time according to the actual environment of the indoor heat exchanger pipeline.
Optionally, the humidity value is obtained by a humidity sensor provided at the indoor heat exchanger pipe. By adopting the optional embodiment, the humidity sensor is arranged at the position close to the indoor heat exchanger pipeline or on the indoor heat exchanger pipeline, so that the humidity value at the position of the indoor heat exchanger pipeline can be accurately monitored, the environmental condition of the indoor heat exchanger pipeline is obtained, and the indoor heat exchanger pipeline is timely and effectively protected.
Optionally, the humidity value is obtained by a humidity sensor disposed in the indoor environment. An air conditioner is generally provided with a humidity sensor for measuring the humidity of an indoor environment in the indoor environment, for example, an indoor unit control panel, and although the humidity sensor is at a certain distance from an indoor heat exchanger pipeline, the humidity value obtained by the humidity sensor can approximately reflect the ambient humidity of the indoor heat exchanger pipeline, and can be converted to be used as the humidity value of the environment where the indoor heat exchanger pipeline is located. By adopting the optional embodiment, the negative voltage applied to the indoor heat exchanger pipeline is controlled by the indoor environment humidity value obtained by the existing humidity sensor of the air conditioner, so that the humidity sensor circuit can be simplified, and the indoor heat exchanger pipeline can be effectively protected in time.
Alternatively, the humidity value is obtained by a humidity sensor provided at the outdoor unit. Because the running state of the air conditioner is closely related to the outdoor environment, the humidity value of the environment where the indoor heat exchanger pipeline is located can be obtained through conversion of the humidity sensor at the outdoor unit, therefore, the negative voltage applied to the indoor heat exchanger pipeline is controlled according to the humidity value of the outdoor environment, the humidity sensor circuit can be simplified, and the indoor heat exchanger pipeline can be effectively protected in time.
Optionally, the method further comprises: and when the humidity value of the environment where the indoor heat exchanger pipeline is located meets a first humidity condition, controlling the negative voltage applied to the indoor heat exchanger pipeline to be the first voltage value. Optionally, the first humidity condition is a humidity value of 60 (relative humidity) or more. Optionally, the first voltage value is 3-12V. By adopting the embodiment, when the humidity value of the environment where the indoor heat exchanger pipeline is located meets the condition, the negative voltage applied to the indoor heat exchanger pipeline is controlled according to the humidity value, because the environment humidity is still possibly high when the air conditioner operates in a standby state, a heating state or an air supply state in southeast Asia or coastal areas, and the problem of untimely implementation can occur by simply taking the operating state of the air conditioner as the basis of implementing anti-corrosion measures, therefore, by adopting the embodiment, the anti-corrosion treatment can be more effectively carried out on the indoor heat exchanger pipeline. For example, when the humidity value of the environment where the indoor heat exchanger pipeline is located is 65, the air conditioner controller controls the output voltage of the power conversion circuit to be-5V, negative voltage of-5V is applied to the indoor heat exchanger pipeline, electrons flow to the part, needing to be protected, of the indoor heat exchanger pipeline and neutralize cations in time, and the indoor heat exchanger pipeline is protected from being rusted by oxidation.
Optionally, when the humidity value of the environment in which the indoor heat exchanger pipeline is located meets a second humidity condition, the negative voltage applied to the indoor heat exchanger pipeline is controlled to be the second voltage value. Optionally, the second humidity condition is a humidity value of 50 or more and less than 60. Optionally, the second voltage value is 20% to 50% of the first voltage value. By adopting the embodiment, the negative voltage applied to the indoor heat exchanger pipeline is reduced according to the humidity value of the environment where the indoor heat exchanger pipeline is located, and the electric energy consumed by implementing anti-corrosion measures can be saved. For example, when the humidity value of the environment where the indoor heat exchanger pipeline is located is 65, the air conditioner controller controls the output voltage of the power conversion circuit to be-5V, and negative voltage of-5V is applied to the indoor heat exchanger; when the humidity value of the environment where the indoor heat exchanger pipeline is located is 55, the air conditioner controller controls the output voltage of the power conversion circuit to be-2.5V, and negative voltage of-2.5V is applied to the indoor heat exchanger pipeline.
Optionally, the negative voltage applied to the indoor heat exchanger line is turned off when the humidity value of the environment in which the indoor heat exchanger line is located satisfies a third humidity condition. Optionally, the third humidity condition is a humidity value of less than 50. By adopting the embodiment, when the humidity value of the environment where the indoor heat exchanger pipeline is located is lower, the negative voltage applied to the indoor heat exchanger pipeline is turned off in time, and the electric energy consumed by implementing anti-corrosion measures can be saved. For example, when the humidity value of the environment in which the indoor heat exchanger pipeline is located is less than 50, the air conditioner controller controls the output voltage of the power conversion circuit to be turned off, and the negative voltage applied to the indoor heat exchanger pipeline is turned off.
Optionally, when the humidity value of the environment in which the indoor heat exchanger pipeline is located meets a fourth humidity condition, the negative voltage applied to the indoor heat exchanger pipeline is controlled to be the fourth voltage value. Optionally, the fourth humidity condition is a humidity value of 70 or higher. Optionally, the fourth voltage value is 1.3 to 1.5 times the first voltage value. By adopting the embodiment, when the humidity value of the environment where the indoor heat exchanger pipeline is located meets the condition, the indoor heat exchanger pipeline is indicated to be located in a higher humidity environment, the negative voltage applied to the indoor heat exchanger pipeline is increased, the negative charge flowing through the surface of the indoor heat exchanger pipeline is increased, and the anti-corrosion treatment is more effectively carried out on the indoor heat exchanger pipeline. For example, when the humidity value of the environment in which the indoor heat exchanger pipe is located is 65, the controller of the air conditioner controls the negative voltage applied to the indoor heat exchanger pipe to be-5V; when the humidity value of the environment where the indoor heat exchanger pipeline is located is 75, the controller of the air conditioner controls the negative voltage applied to the indoor heat exchanger pipeline to be-7.5V.
Fig. 4 illustrates another alternative embodiment of a method for protecting the indoor heat exchanger tubes of an air conditioner.
In this embodiment, the method further includes: step 31, acquiring the running state of the air conditioner and the humidity value of the environment where the indoor heat exchanger pipeline is located; and step 32, controlling the negative voltage applied to the indoor heat exchanger pipeline according to the running state of the air conditioner and the humidity value of the environment where the indoor heat exchanger pipeline is located. By adopting the embodiment, the negative voltage applied to the indoor heat exchanger pipeline can be controlled together according to the running state of the air conditioner and the humidity value of the environment where the indoor heat exchanger pipeline is located, so that the reliable implementation of the anti-corrosion measures is realized, and the situation that the anti-corrosion measures are not timely due to the fact that the anti-corrosion measures are implemented singly according to the running state of the air conditioner or the humidity value of the environment where the indoor heat exchanger pipeline is located is prevented.
Optionally, when the humidity value of the environment in which the indoor heat exchanger pipeline is located does not meet the negative voltage opening condition, the negative voltage applied to the indoor heat exchanger pipeline is controlled according to the running state of the air conditioner. By adopting the embodiment, metal oxidation can still occur in the environment with a lower humidity value after long-time operation, so that the negative voltage applied to the indoor heat exchanger pipeline is controlled according to the operation state of the air conditioner, the reliable implementation of anti-corrosion measures can be realized, and the situation that the anti-corrosion measures are not timely is avoided. For example, when the indoor heat exchanger line is in an environment with a humidity value of 45, the air conditioner is operated in a cooling or dehumidifying state, and the negative voltage applied to the indoor heat exchanger line is controlled according to the operating state of the air conditioner.
Optionally, when the operation state of the air conditioner does not satisfy the negative voltage opening condition, the negative voltage applied to the indoor heat exchanger pipeline is controlled according to the humidity value of the environment in which the indoor heat exchanger pipeline is located. By adopting the embodiment, for southeast Asia or coastal areas, when the air conditioner runs in a standby state, a heating state or an air supply state, the environment humidity is still possibly high, and the problem of untimely implementation can occur by simply taking the running state of the air conditioner as the basis for implementing anti-corrosion measures, so that the indoor heat exchanger pipeline can be more effectively subjected to anti-corrosion treatment by adopting the embodiment. For example, when the air conditioner is operated in a standby, heating or blowing state, the negative voltage applied to the indoor heat exchanger line is controlled according to the humidity value of the environment in which the indoor heat exchanger line is located.
Optionally, when the operating state of the air conditioner and the humidity value of the environment in which the indoor heat exchanger pipeline is located both satisfy the negative voltage opening condition, the negative voltage applied to the indoor heat exchanger pipeline is controlled according to the humidity value of the environment in which the indoor heat exchanger pipeline is located in a manner of giving priority to the humidity value of the environment in which the indoor heat exchanger pipeline is located.
By adopting the embodiment, the humidity value of the environment where the indoor heat exchanger pipeline is located can more directly reflect whether the indoor heat exchanger pipeline is oxidized, and the corrosion prevention of the indoor heat exchanger pipeline can be more effectively realized by adopting the mode that the humidity value of the environment where the indoor heat exchanger pipeline is located is prior.
Alternatively, the method for controlling the negative voltage applied to the indoor heat exchanger line according to the operation state of the air conditioner may employ the same embodiments as those of the embodiment shown in fig. 2 and its alternative embodiment.
Alternatively, the method for controlling the negative voltage applied to the indoor heat exchanger pipeline according to the humidity value of the environment where the indoor heat exchanger pipeline is located adopts the same implementation manner as the embodiment shown in fig. 3 and the alternative embodiment thereof.

By adopting the embodiment, a negative voltage is applied to the indoor heat exchanger pipeline 100, current flows through the indoor heat exchanger pipeline, when electrolyte cations in the environment carry out cation ionization oxidation on metal at a certain position on the indoor heat exchanger pipeline, electrons flow to the part of the indoor heat exchanger pipeline to be protected and neutralize the cations, the indoor heat exchanger pipeline is protected from being oxidized and corroded, and the service life of the air conditioner is prolonged; moreover, since the liquid inlet and outlet pipes of the indoor heat exchanger are connected to ground potential, all the parts of the indoor heat exchanger pipes which are electrically protected are reliably grounded, and electrons are guided to and flow away from the ground wire.
Alternatively, the output voltage of the power conversion circuit 30 is-3V to-12V, i.e., the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 is-3V to-12V. By adopting the embodiment, negative voltage of-3V to-12V can effectively provide electrons required by cation neutralization, and the electricity safety is ensured.
Optionally, the ground terminal of the power conversion circuit 30 is connected to the liquid inlet pipe 7 and the liquid outlet pipe 8 of the indoor heat exchanger through a ground wire and a metal clip.

Alternatively, the first unit 201 controls the switching on or off of the output voltage of the power conversion circuit 30, and thus controls the switching on or off of the negative voltage applied to the indoor heat exchanger line 100, according to the operation state of the air conditioner. Alternatively, the first unit 201 controls the on or off of the output voltage of the power conversion circuit 30 and the magnitude of the output voltage according to the operation state of the air conditioner. By adopting the embodiment, the first unit 201 controls the negative voltage applied to the indoor heat exchanger pipeline by the power conversion circuit according to the running state of the air conditioner, so that the electric energy consumed by corrosion prevention of the air conditioner can be saved, and the energy consumption of the air conditioner is reduced.
Optionally, the query unit 210 obtains the operation state of the air conditioner 40 by looking up a table or reading an interrupt flag.

Optionally, the first unit 201 is further configured to control the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 to be a first voltage value when the air conditioner is operated in a cooling state or a dehumidification state. Optionally, the first voltage value is-3 to-12V. With this embodiment, when the air conditioner is in a cooling state or a dehumidification state, the indoor heat exchanger pipeline is in a humid environment or even in an environment with moisture, and therefore, the first unit 201 controls the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 to be the first voltage value, so that sufficient negative charges can be provided for the indoor heat exchanger pipeline 100, and effective corrosion protection can be performed on the indoor heat exchanger pipeline 100.
Optionally, the first unit 201 is further configured to turn off the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 when the air conditioner is operating in a standby state, a heating state, or a blowing state. By adopting the embodiment, because the indoor heat exchanger pipeline is in a dry state, all the parts are relatively stable, the oxidation resistance is higher, at this time, the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 is turned off without starting the anti-corrosion protection function, and the energy consumption of the air conditioner can be saved.
Optionally, the first unit 201 is further configured to turn off the negative voltage applied to the indoor heat exchanger circuit 100 by the power conversion circuit 30 every fixed time interval when the air conditioner is operated in a standby state, or a heating state, or a blowing state. By adopting the embodiment, because the indoor heat exchanger pipeline 100 is in a dry state, all parts are relatively stable, the oxidation resistance is high, and the anticorrosion protection function does not need to be started all the time, the negative voltage applied to the indoor heat exchanger pipeline 100 is turned off at fixed time intervals, and the electric energy consumed by anticorrosion can be saved.
Optionally, the first unit 201 is further configured to turn off the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 every first time interval when the air conditioner is in the standby state, where the turn-off time is a first turn-off time, the first time interval is 0.5-1 hour, and the first turn-off time is 0.5-2 hours. When the air conditioner 40 is in a standby state, the environment where the indoor heat exchanger pipeline is located is the indoor environment, and the air conditioner just finishes running, so that the indoor humidity value is relatively low, by adopting the embodiment, the first unit 201 controls the power conversion circuit 30 to start negative voltage to run for 0.5-1 hour, so that the anticorrosion measures of the air conditioner in the standby state can be effectively started, electrons flow to the part needing to be protected of the indoor heat exchanger pipeline 100 and neutralize cations in time, the indoor heat exchanger pipeline 100 is protected from being oxidized and corroded, and a good anticorrosion effect is realized; when the time of the first time interval of the operation of starting the negative voltage reaches, the anti-corrosion measures are finished, the time of the first time interval can reach a better anti-corrosion effect, and the first unit 201 turns off the power conversion circuit 30 to output the negative voltage for the first turn-off time, so that the energy consumption of the anti-corrosion measures in the standby state can be saved.

Because the environment of the indoor heat exchanger pipeline is dry when the air conditioner is in a heating state, the oxidized area of the indoor heat exchanger pipeline is small, and the speed is low, by adopting the embodiment, the first unit 201 controls the power conversion circuit 30 to start negative voltage for 10-20 minutes, so that the anti-corrosion measures can be effectively started in the heating state time period of the air conditioner, electrons flow to the part of the indoor heat exchanger pipeline to be protected and neutralize cations in time, and the indoor heat exchanger pipeline is protected from being oxidized and rusted; when the time of starting the negative voltage and operating the second time interval is up, the anti-corrosion measures are completed, a good anti-corrosion effect can be achieved, and due to the fact that the oxidized area of the indoor heat exchanger pipeline is small and the speed is low in the heating state, the first unit 201 is turned off, the power conversion circuit outputs the negative voltage for 2-4 hours, and energy consumption of the anti-corrosion measures in the heating state can be saved.
Optionally, the first unit 201 is further configured to turn off the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 every third time interval when the air conditioner 40 is in the air blowing state, where the turn-off time is a third turn-off time, the third time interval is 5-10 minutes, and the third turn-off time is 2-4 hours. Because the environment of the indoor heat exchanger pipeline is dry when the air conditioner is in an air supply state, the oxidized area of the indoor heat exchanger pipeline is small, and the speed is low, by adopting the embodiment, the first unit 201 controls the power conversion circuit 30 to start negative voltage for 5-10 minutes, so that the anti-corrosion measures can be effectively started when the air conditioner is in the air supply state, electrons flow to the part needing to be protected of the indoor heat exchanger pipeline 100 and neutralize cations in time, and the indoor heat exchanger pipeline is protected from being corroded and oxidized; when the time of starting the negative voltage and running the third time interval is up, the anti-corrosion measures are finished, a good anti-corrosion effect can be achieved, and due to the fact that the oxidized area of the indoor heat exchanger pipeline is small and the speed is low in the air supply state, the first unit 201 controls the power conversion circuit 30 to switch off the negative voltage for 2-4 hours, and energy consumption of the anti-corrosion measures in the air supply state is saved.
Optionally, the first unit is further configured to reduce a negative voltage applied to the indoor heat exchanger line when the air conditioner is operated in a standby state, or a heating state, or a blowing state. With this embodiment, since the environment of the indoor heat exchanger pipeline 100 is dry, the components are relatively stable, and the oxidation resistance is high when the air conditioner 40 is in the standby state, the heating state, or the air blowing state, it is not necessary for the power conversion circuit 30 to always apply a high negative voltage to the indoor heat exchanger pipeline 100 to provide the anti-corrosion protection function, and therefore, the first unit 201 controls the power conversion circuit 30 to reduce the negative voltage applied to the indoor heat exchanger pipeline 100, and the electric energy consumed by the anti-corrosion measures can be saved.
Optionally, the first unit 201 is further configured to control the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 to be a second voltage value when the air conditioner is operated in a standby state, a heating state, or a blowing state, where the second voltage value is 20% to 50% of the first voltage value. With this embodiment, the electrical energy consumed for implementing the anti-corrosion measures can be saved. For example, when the air conditioner is operated in a cooling state or a dehumidifying state, the first unit 201 controls the negative voltage applied to the indoor heat exchanger line 100 by the power conversion circuit 30 to be-5V; when the air conditioner is operated in a standby state, a heating state or a blowing state, the first unit 201 controls the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 to be-2.5V.
Fig. 7 shows another alternative embodiment of an apparatus for protecting the piping of an indoor heat exchanger of an air conditioner.
In this embodiment, the apparatus 200 further includes a humidity sensor 50 and a second unit 202, where the humidity sensor 50 is used to obtain a humidity value of an environment where the indoor heat exchanger pipeline 100 is located; the second unit 202 is configured to control the negative voltage applied to the indoor heat exchanger circuit 100 by the power conversion circuit 30 according to the humidity value. Optionally, the second unit 202 is configured to control the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 to be turned on or off according to a humidity value of an environment in which the indoor heat exchanger pipeline 100 is located. Optionally, the second unit 202 is configured to control the on or off of the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 and the magnitude of the negative voltage according to the humidity value of the environment in which the indoor heat exchanger pipeline 100 is located. For areas with high environmental humidity, the operating state of the air conditioner cannot be used as the basis for implementing anti-corrosion measures. By adopting the embodiment, the negative voltage applied to the indoor heat exchanger pipeline can be controlled according to the actual environment where the indoor heat exchanger pipeline is located, and the indoor heat exchanger pipeline can be effectively protected in time according to the actual environment of the indoor heat exchanger pipeline.
Optionally, the humidity sensor 50 is disposed at the heat exchanger pipe 100, and the humidity value is obtained by the humidity sensor 50 disposed at the indoor heat exchanger pipe 100. By adopting the optional embodiment, the humidity sensor is arranged at the position close to the indoor heat exchanger pipeline or on the indoor heat exchanger pipeline, so that the humidity value at the position of the indoor heat exchanger pipeline can be accurately monitored, the environmental condition of the indoor heat exchanger pipeline is obtained, and the indoor heat exchanger pipeline is timely and effectively protected.
Alternatively, the humidity sensor 50 is disposed in an indoor environment, and the humidity value is obtained by the humidity sensor disposed in the indoor environment. The air conditioner 40 is usually provided with a humidity sensor for measuring the humidity of the indoor environment in the indoor environment, for example, at an indoor machine control panel, and although the humidity sensor is located at a certain distance from the indoor heat exchanger pipeline, the humidity value obtained by the humidity sensor can approximately reflect the ambient humidity of the indoor heat exchanger pipeline, and can be converted to be the humidity value of the environment where the indoor heat exchanger pipeline is located. With this embodiment, the second unit 202 controls the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 according to the indoor environment humidity value obtained by the existing humidity sensor of the air conditioner, so that the humidity sensor circuit can be simplified, and the indoor heat exchanger pipeline can be protected timely and effectively.
Alternatively, the humidity sensor 50 is provided at the outdoor unit, and the humidity value is obtained by the humidity sensor provided at the outdoor unit. Because the running state of the air conditioner is closely related to the outdoor environment, the humidity value of the environment where the indoor heat exchanger pipeline is located can be obtained through conversion of the humidity sensor at the outdoor unit, therefore, the negative voltage applied to the indoor heat exchanger pipeline is controlled according to the humidity value of the outdoor environment, the humidity sensor circuit can be simplified, and the indoor heat exchanger pipeline can be effectively protected in time.
Optionally, the second unit 202 is further configured to control the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 to be the first voltage value when the humidity value of the environment in which the indoor heat exchanger pipeline is located satisfies the first humidity condition. Optionally, the first humidity condition is a humidity value of 60 (relative humidity) or more. Optionally, the first voltage value is 3-12V. With this embodiment, when the humidity value of the environment in which the indoor heat exchanger pipeline is located satisfies the condition, the second unit 202 controls the power conversion circuit 30 to apply the negative voltage to the indoor heat exchanger pipeline 100 according to the humidity value, because the environment humidity may still be high when the air conditioner operates in the standby state, the heating state, or the blowing state in southeast asia or coastal areas, and simply taking the operating state of the air conditioner as the basis for implementing the anti-corrosion measure, the problem of untimely implementation may occur, and therefore, with this embodiment, the apparatus may more effectively perform the anti-corrosion treatment on the indoor heat exchanger pipeline. For example, when the humidity value of the environment where the indoor heat exchanger pipeline is located is 65, the second unit 202 controls the output voltage of the power conversion circuit to be-5V, a negative voltage of-5V is applied to the indoor heat exchanger pipeline 100, and electrons flow to the part of the indoor heat exchanger pipeline 100 to be protected and neutralize cations in time, so as to protect the indoor heat exchanger pipeline 100 from being rusted by oxidation.
Optionally, the second unit 202 is further configured to control the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 to be the second voltage value when the humidity value of the environment in which the indoor heat exchanger pipeline is located satisfies the second humidity condition. Optionally, the second humidity condition is a humidity value of 50 or more and less than 60. Optionally, the second voltage value is 20% to 50% of the first voltage value. With this embodiment, the second unit 202 reduces the negative voltage applied to the indoor heat exchanger conduit 100 by the power conversion circuit 30 according to the humidity value of the environment in which the indoor heat exchanger conduit 100 is located, and can save the electric energy consumed for implementing the anti-corrosion measures. For example, when the humidity value of the environment in which the indoor heat exchanger pipeline 100 is located is 65, the second unit 202 controls the output voltage of the power conversion circuit 30 to be-5V, and applies a negative voltage of-5V to the indoor heat exchanger pipeline 100; when the humidity value of the environment where the indoor heat exchanger pipeline 100 is located is 55, the second unit 202 controls the output voltage of the power conversion circuit 30 to be-2.5V, and applies a negative voltage of-2.5V to the indoor heat exchanger pipeline 100.
Optionally, the second unit 202 is further configured to turn off the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 when the humidity value of the environment in which the indoor heat exchanger pipeline 100 is located satisfies a third humidity condition. Optionally, the third humidity condition is a humidity value of less than 50. With this embodiment, when the humidity value of the environment in which the indoor heat exchanger pipeline is located is low, the second unit 202 turns off the negative voltage applied to the indoor heat exchanger pipeline 100 in time, so that the electric energy consumed for implementing the anti-corrosion measure can be saved. For example, when the humidity value of the environment in which the indoor heat exchanger circuit 100 is located is less than 50, the second unit 202 controls the output voltage of the power conversion circuit 30 to be turned off, and turns off the negative voltage applied to the indoor heat exchanger circuit 100.
Optionally, the second unit 202 is further configured to control the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 to be a fourth voltage value when the humidity value of the environment in which the indoor heat exchanger pipeline is located satisfies a fourth humidity condition. Optionally, the fourth humidity condition is a humidity value of 70 or higher. Optionally, the fourth voltage value is 1.3 to 1.5 times the first voltage value. With this embodiment, when the humidity value of the environment in which the indoor heat exchanger pipeline 100 is located satisfies the condition, it is indicated that the indoor heat exchanger pipeline 100 is located in a higher humidity environment, the negative voltage applied to the indoor heat exchanger pipeline 100 is increased, the negative charge flowing through the surface of the indoor heat exchanger pipeline 100 is increased, and the anti-corrosion treatment is more effectively performed on the indoor heat exchanger pipeline 100. For example, when the humidity value of the environment in which the indoor heat exchanger pipeline 100 is located is 65, the second unit 202 controls the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 to be-5V; when the humidity value of the environment in which the indoor heat exchanger pipeline 100 is located is 75, the second unit 202 controls the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 to be-7.5V.

With this embodiment, the third unit 203 can control the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 according to the operating state of the air conditioner and the humidity value of the environment where the indoor heat exchanger pipeline is located, so as to implement reliable anticorrosion measures, and prevent the situation that the anticorrosion measures are not timely due to the implementation of the anticorrosion measures according to the operating state of the air conditioner or the humidity value of the environment where the indoor heat exchanger pipeline is located.
Optionally, the third unit 203 is further configured to control the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 according to the operation state of the air conditioner 40 when the humidity value of the environment in which the indoor heat exchanger pipeline 100 is located does not satisfy the negative voltage opening condition. With this embodiment, in an environment with a low humidity value, metal oxidation may still occur when the air conditioner is operated for a long time, and therefore, the third unit 203 controls the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 according to the operation state of the air conditioner 40, so that reliable implementation of anti-corrosion measures can be realized, and the situation that the anti-corrosion measures are not implemented timely can be avoided. For example, when the humidity value of the environment in which the indoor heat exchanger line 100 is located is 45 and the air conditioner 40 is operated in the cooling or dehumidifying state, the third unit 203 controls the negative voltage applied to the indoor heat exchanger line 100 by the power conversion circuit 30 according to the operation state of the air conditioner 40.

With this embodiment, in the southeast asia or coastal areas, when the air conditioner 40 is in a standby state, a heating state, or an air supply state, the ambient humidity may still be high, and simply using the air conditioner operating state as the basis for implementing the anti-corrosion measures, the problem of untimely implementation of the anti-corrosion measures may occur, and therefore, with this embodiment, the apparatus 200 may more effectively perform the anti-corrosion treatment on the indoor heat exchanger pipeline 100.
Optionally, the third unit 203 is further configured to control the negative voltage applied to the indoor heat exchanger pipeline 100 by the power conversion circuit 30 according to the humidity value of the environment in which the indoor heat exchanger pipeline 100 is located, in a manner of giving priority to the humidity value of the environment in which the indoor heat exchanger pipeline 100 is located when both the operation state of the air conditioner 40 and the humidity value of the environment in which the indoor heat exchanger pipeline 100 is located satisfy the negative voltage opening condition. By adopting the embodiment, whether the indoor heat exchanger pipeline is oxidized or not can be more directly reflected by the humidity value of the environment where the indoor heat exchanger pipeline is located, and the corrosion prevention of the indoor heat exchanger pipeline can be more effectively realized by adopting the mode that the humidity value of the environment where the indoor heat exchanger pipeline is located is prior.
