Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner control methods, and in particular to an air conditioner adaptive anti-corrosion control method, an air conditioner for implementing the method, and a computer-readable storage medium. Background Art

[0002] At present, air conditioners, as a device that can adjust the temperature and humidity of the environment, have been widely used in various fields and environments.

[0003] During the cooling operation of the air conditioner, the evaporator of the indoor unit of the air conditioner will produce condensed water, causing liquid water to condense on the copper tube of the evaporator, which will accelerate the oxidation reaction between the copper tube and the oxygen in the air, causing the copper tube of the evaporator to be gradually corroded. Especially when used for a long time in high humidity environments such as islands, ditches, and rivers, the copper tube of the evaporator will corrode faster and may even cause the copper tube to rupture, seriously affecting the service life of the air conditioner.

[0004] In order to prevent the evaporator from corrosion, existing air conditioners are equipped with a humidity sensor and a heating element in the indoor unit. The humidity sensor detects the real-time humidity at the evaporator. When the real-time humidity at the evaporator is greater than the preset humidity, the heating element is controlled to turn on to heat and dehumidify the copper tube of the evaporator to remove moisture on the surface of the copper tube of the evaporator, thereby preventing the copper tube of the evaporator from corrosion.

[0005] However, existing air conditioners require the heating element to be on for a period of time before the real-time humidity at the evaporator drops below a preset level. Prolonged heating of the copper tube can overheat the refrigerant flowing into it, affecting the air conditioner's cooling performance and, consequently, cooling comfort. Furthermore, when the humidity sensor detects that the real-time humidity at the evaporator is near the threshold of the preset humidity, the heating element will frequently start and stop, increasing energy consumption. Furthermore, existing air conditioners require the addition of a humidity sensor and heating element to the existing indoor unit, increasing both cost and design complexity. Summary of the Invention

[0006] The first purpose of the present invention is to provide an air-conditioning adaptive anti-corrosion control method, which can adaptively control the working status of the indoor fan and indoor air guide plate according to the real-time tube temperature of the evaporator and revise the heating operation frequency of the compressor to ensure the reliability and stability of the anti-corrosion mode operation, and achieve a better dehydration effect on the copper tube of the evaporator, thereby achieving a better anti-corrosion effect on the copper tube of the evaporator, and no need to add any components on the basis of the original air-conditioning indoor unit to achieve a better dehydration effect on the copper tube of the evaporator, thereby saving costs and reducing the design difficulty of the product structure, and will not affect the refrigeration performance of the air conditioner, thereby improving the refrigeration comfort of the air conditioner.

[0008] A third object of the present invention is to provide a computer-readable storage medium for implementing the above-mentioned air conditioning adaptive anti-corrosion control method.

[0009] In order to achieve the first object of the present invention, the present invention provides an air conditioner adaptive anti-corrosion control method, comprising: controlling the air conditioner to start up and execute the cooling mode operation; when the duration of the air conditioner executing the cooling mode operation is greater than a preset time and the air conditioner executes the shutdown instruction, controlling the air conditioner to execute the anti-corrosion mode; the anti-corrosion mode includes: controlling the air conditioner to execute the heating mode operation and controlling the outdoor fan to operate at the highest wind speed; obtaining the real-time pipe temperature of the evaporator , the real-time pipe temperature Compare with the budgeted pipe temperature conditions to control the working status of the indoor fan and indoor air guide plate, and revise the heating operation frequency of the compressor; when it is determined that the preset exit conditions are met, the air conditioner is controlled to exit the anti-corrosion mode and shut down.

[0010] It can be seen from the above scheme that the adaptive anti-corrosion control method for air conditioners of the present invention automatically controls the air conditioner to execute the anti-corrosion mode only after the air conditioner executes the cooling mode and shuts down, so that the operation of the anti-corrosion mode will not affect the cooling performance of the air conditioner, thereby improving the cooling comfort of the air conditioner.

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is the main flow chart of an embodiment of the air conditioning adaptive anti-corrosion control method of the present invention.

[0021] Figure 2 It is a branch flow chart of an embodiment of the air conditioning adaptive anti-corrosion control method of the present invention.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0023] Air conditioning adaptive anti-corrosion control method embodiment: The air conditioner in this embodiment includes an indoor unit and an outdoor unit. The indoor unit is provided with an evaporator, an indoor fan, an indoor air guide plate and an air outlet, wherein the indoor air guide plate is used to close or open the air outlet of the indoor unit, and the outdoor unit is provided with an outdoor fan, a compressor and a condenser.

[0024] See also Figure 1 , is the main flow chart of the air conditioning adaptive anti-corrosion control method of this embodiment, and the specific steps are as follows.

[0025] First, execute step S11 to control the air conditioner to turn on, that is, the user sends a power-on signal to the indoor unit of the air conditioner through the remote control, and the circuit board of the indoor unit receives the power-on signal and executes the power-on command. Then execute step S12 to control the air conditioner to run in cooling mode, that is, the user sends a cooling mode operation signal to the indoor unit through the remote control, and the circuit board of the indoor unit receives the cooling mode operation signal, thereby controlling the air conditioner to run in cooling mode.

[0026] Next, step S13 is executed to determine whether the duration of the air conditioner executing the cooling mode operation is greater than a preset time. If so, step S14 is executed; if not, step S12 is executed to continuously control the air conditioner to execute the cooling mode operation.

[0027] If step S13 determines that the air conditioner has been operating in cooling mode for longer than the preset time, indicating that the indoor unit's evaporator has produced a certain amount of condensed water, posing a risk of corrosion to the evaporator's copper tubes, step S14 is executed, and the air conditioner executes a shutdown command. Specifically, if the user sends a shutdown command to the indoor unit via the remote control, the indoor unit's circuit board receives the shutdown command and executes it, thereby stopping the air conditioner. Specifically, in this embodiment, the preset time is 10 minutes.

[0028] Then, step S15 is executed to control the air conditioner to execute the anti-corrosion mode. That is, if it is determined that the duration of the air conditioner executing the cooling mode is greater than the preset time and the air conditioner executes the shutdown instruction, the air conditioner automatically executes the anti-corrosion mode. After the air conditioner enters the anti-corrosion mode, step S16 is executed. The number of executions of the anti-corrosion mode is It increases automatically once, controls the air conditioner to run in heating mode, and controls the outdoor fan to run at the highest wind speed, so that the temperature of the evaporator rises quickly, so as to dry and remove the liquid water condensed on the copper tube of the evaporator.

[0029] Then, execute step S17 to obtain the real-time tube temperature of the evaporator. , the real-time tube temperature Compare with the budgeted pipe temperature conditions to control the working status of the indoor fan and indoor air guide plate, and revise the heating operation frequency of the compressor to ensure the reliability and stability of the anti-corrosion mode operation, achieve better water removal effect on the copper tube of the evaporator, and thus achieve better anti-corrosion effect on the copper tube of the evaporator.

[0030] Then, step S18 is executed to determine whether the preset exit condition is met. If so, step S19 is executed; if not, step S17 is executed to continue to set the real-time pipe temperature to Compare with the budgeted pipe temperature conditions to control the working status of the indoor fan and indoor air guide plate, and revise the heating operation frequency of the compressor to ensure the reliability and stability of the anti-corrosion mode operation, achieve better water removal effect on the copper tube of the evaporator, and thus achieve better anti-corrosion effect on the copper tube of the evaporator.

[0031] When step S18 determines that the preset exit condition is met, step S19 is executed to control the air conditioner to exit the anti-corrosion mode and shut down.

[0032] Therefore, the air conditioner adaptive anti-corrosion control method of this embodiment automatically controls the air conditioner to execute the anti-corrosion mode after the air conditioner executes the cooling mode and shuts down, so that the anti-corrosion mode operation will not affect the cooling performance of the air conditioner, thereby improving the cooling comfort of the air conditioner. Moreover, the air conditioner adaptive anti-corrosion control method of this embodiment can achieve a better water removal effect on the copper tube of the evaporator without adding any components on the basis of the original air conditioner indoor unit, thereby saving costs and reducing the difficulty of product structure design. Moreover, the air conditioner adaptive anti-corrosion control method of this embodiment can control the air conditioner to execute the anti-corrosion mode according to the real-time tube temperature of the evaporator during the process of controlling the air conditioner to execute the anti-corrosion mode. Adaptively control the working status of the indoor fan and indoor air guide plate and revise the heating operation frequency of the compressor to ensure the reliability and stability of the anti-corrosion mode operation, achieve better water removal effect on the copper tube of the evaporator, and thus achieve better anti-corrosion effect on the copper tube of the evaporator.

[0033] Specifically, the preset exit condition in this embodiment is one of the following three conditions: Condition (1): Satisfy The cumulative duration of the condition reaches the first preset duration, where The first budget pipe temperature; Condition (2): The operating time of the compressor reaches a second preset time, and the second preset time is greater than the first preset time; Condition (3): The number of times the air conditioner executes the over-temperature protection mode reaches the preset number, and the over-temperature protection mode controls the air conditioner to shut down.

[0034] Preferably, the first preset duration in this embodiment is 8 minutes, the second preset duration in this embodiment is 10 minutes, and the preset number of times in this embodiment is twice.

[0035] In the process of controlling the air conditioner to execute the anti-corrosion mode operation, when the condition (1) is satisfied, that is, when the condition (1) is satisfied, the air conditioner is controlled to execute the anti-corrosion mode operation. The cumulative time of the condition reaches 8 minutes, indicating that the air conditioner is running in heating mode, which makes the real-time pipe temperature of the evaporator The temperature is raised to dry the liquid water condensed on the copper tube of the evaporator for 8 minutes to achieve a better dehydration effect, and the air conditioner is controlled to exit the anti-corrosion mode and shut down; or, when condition (2) is met, that is, when the running time of the compressor reaches the second preset time, since the second preset time is greater than the first preset time in condition (1), when condition (1) is not met, it means that the air conditioner is running in the heating mode and is affected by the indoor environment, causing the real-time tube temperature of the evaporator to be If the temperature rises slowly, the compressor is operated for 10 minutes to extend the dehydration time to achieve a better dehydration effect, and the air conditioner is controlled to exit the anti-corrosion mode and shut down; or, when condition (3) is met, that is, the number of times the air conditioner executes the over-temperature protection mode reaches the preset number, the over-temperature protection mode is to control the air conditioner to shut down, indicating that the air conditioner executes the heating mode to make the real-time pipe temperature of the evaporator The temperature rises very quickly, causing the air conditioner to execute the over-temperature protection mode to shut down to avoid high-temperature damage to the air conditioner. However, when the air conditioner executes the over-temperature protection mode to shut down, the real-time pipe temperature of the evaporator will The water removal effect of the copper tube of the evaporator is affected by the temperature drop. Therefore, the preset number of times in this embodiment is two, that is, after the air conditioner executes the first over-temperature protection mode, it restarts and controls the air conditioner to execute the heating mode to ensure the water removal effect of the copper tube of the evaporator. With the restart of the air conditioner to execute the heating mode, the real-time tube temperature of the evaporator is increased. When the temperature rises quickly, the air conditioner will execute the second over-temperature protection mode and shut down, indicating that the real-time pipe temperature of the higher temperature evaporator is too high. When a better water removal effect has been achieved, the air conditioner is controlled to exit the anti-corrosion mode and shut down.

[0036] Therefore, the three preset exit conditions set in the air conditioner adaptive anti-corrosion control method of this embodiment can ensure that a better water removal effect is achieved on the copper tube of the evaporator, thereby achieving a better anti-corrosion effect on the copper tube of the evaporator.

[0037] Specifically, the estimated pipe temperature conditions in this embodiment include the first estimated pipe temperature , Second budget pipe temperature and budget protection pipe temperature .

[0038] See also Figure 2 , which is the first branch flow chart of the air conditioner adaptive anti-corrosion control method of this embodiment, that is, the air conditioner adaptive anti-corrosion control method of this embodiment controls the air conditioner to execute the anti-corrosion mode operation process, and the real-time pipe temperature is set. Compare with the budgeted pipe temperature conditions to control the working status of the indoor fan and indoor air guide plate, and revise the specific method of the heating operation frequency of the compressor. The relevant steps are as follows.

[0039] The air conditioning adaptive anti-corrosion control method of this embodiment performs Figure 1 In step S17, specifically, Figure 2 Step S21 in the process of controlling the air conditioner to execute the anti-corrosion mode, obtain the real-time tube temperature of the evaporator .

[0040] When executing step S22, it is determined that When the temperature of the indoor fan is lowered, step S23 is executed to control the indoor fan to stop running, and the indoor air guide plate is controlled to close the air outlet of the indoor unit, and the compressor is controlled to run at the heating operating frequency when the last anti-corrosion mode was exited. At this time, the indoor fan is controlled to stop running mainly to quickly increase the temperature of the evaporator so as to quickly dry and remove the liquid water condensed on the copper tube of the evaporator.

[0041] As the air conditioner continues to operate in heating mode, the real-time pipe temperature of the evaporator Continue to rise, so step S24 is executed to determine whether When the temperature is high, step S25 is executed to control the indoor fan to run at the lowest wind speed, control the indoor air guide plate to close the air outlet of the indoor unit, and control the compressor to run at the heating operation frequency when the anti-corrosion mode was exited last time, so as to meet the requirements. When the water removal effect of the copper tube of the evaporator has reached the expected anti-corrosion requirements, the indoor fan is controlled to run at the lowest wind speed so that the hot air stays in the indoor unit as much as possible to ensure the real-time tube temperature of the evaporator. Stable The copper tube of the evaporator is continuously dried and dehydrated within the range to achieve better dehydration effect.

[0042] When the condition is met, step S26 is executed to determine whether the condition is met. When the evaporator is in real time, the temperature of the tube is If the temperature is too high and the over-temperature protection is likely to occur, step S27 is executed to control the indoor fan to run at the lowest wind speed and control the indoor air guide plate to close the air outlet of the indoor unit. Then step S28 is executed to determine the heating operation frequency of the compressor when the anti-corrosion mode was exited last time. Is it the preset lower limit frequency of the compressor? If so, execute step S29 to control the compressor to run at the preset lower limit frequency; if not, execute step S210 to control the compressor to run at the revised frequency. Operation, revision frequency ,in The preset revision frequency is: is 1HZ.

[0043] Once the air conditioner is shut down and restarted due to over-temperature protection, the real-time pipe temperature of the evaporator will be The decrease affects the water removal effect, so when it is determined to meet When there is a situation that may easily cause the air conditioner to overheat, the heating operation frequency of the compressor is reduced to avoid the real-time pipe temperature of the evaporator. The temperature rises too quickly and over-temperature protection occurs, thereby achieving a better water removal effect on the copper tube of the evaporator.

[0044] Once the condition is met, step S211 is executed to determine whether the condition is met. When the evaporator is in real time, the temperature of the tube is Exceeding the budget protection pipe temperature , which will cause the air conditioner to be damaged by high temperature, so step S212 is executed to control the air conditioner to execute the over-temperature protection mode, thereby controlling the air conditioner to stop to avoid the air conditioner from being damaged by high temperature, along with the real-time pipe temperature of the evaporator If the preset exit condition is not met to control the air conditioner to exit the anti-corrosion mode, it will restart the air conditioner to run in the heating mode, and the real-time pipe temperature of the evaporator will be Compare with the estimated pipe temperature condition of this embodiment to control the working state of the indoor fan and indoor air guide plate, and revise the heating operation frequency of the compressor, that is, repeat the execution Figure 2 The relevant steps in the process are carried out to achieve better water removal effect on the copper tube of the evaporator.

[0045] In one embodiment, when Conditions and preset exit conditions to exit the last anti-corrosion mode, indicating that the condition (1) or condition (2) of the preset exit conditions of this embodiment is met, and due to the real-time tube temperature of the evaporator Less than the second budget pipe temperature , indicating the real-time tube temperature of the evaporator during the last anti-corrosion mode operation. It is not high and there is a possibility that the best water removal effect has not been achieved, so when the air conditioner executes the next anti-corrosion mode, it is judged that the heating operation frequency of the compressor when the last anti-corrosion mode exited Is it the preset upper limit frequency of the compressor? If so, the compressor is controlled to run at the preset upper limit frequency; if not, the compressor is controlled to run at the revised frequency. Operation, revision frequency and the real-time tube temperature Compare with the budgeted pipe temperature conditions to control the working status of the indoor fan and indoor air guide plate, and revise the heating operation frequency of the compressor, that is, execute Figure 2 The relevant steps in the process are carried out to achieve better water removal effect on the copper tube of the evaporator.

[0046] Therefore, when judging the real-time tube temperature of the evaporator during the last anti-corrosion mode operation, If the temperature is not high and there is a possibility that the best water removal effect has not been achieved, the heating operation frequency of the compressor will be revised to increase the real-time pipe temperature of the evaporator when the air conditioner executes the next anti-corrosion mode. Increase the speed to achieve better water removal effect on the copper tube of the evaporator.

[0047] In one embodiment, the air conditioner adaptive anti-corrosion control method of this embodiment controls the air conditioner to execute the anti-corrosion mode. When the air conditioner executes the first over-temperature protection mode, it restarts and controls the air conditioner to execute the heating mode. Then, the current first budget pipe temperature is determined. Is it the first preset upper limit temperature? If so, keep the current first budget pipe temperature If not, revise the first budget pipe temperature to ; And judge the current second budget pipe temperature is Is it the second preset upper limit temperature? If so, keep the current second budget pipe temperature as If not, revise the second budget pipe temperature to ; And determine the current budget protection pipe temperature Is it the third preset upper limit temperature? If so, keep the current budget protection pipe temperature If not, revise the estimated protection pipe temperature to ; Afterwards, the real-time tube temperature Compare with the budgeted pipe temperature conditions to control the working status of the indoor fan and indoor air guide plate, and revise the heating operation frequency of the compressor, that is, execute Figure 2 The relevant steps in the process are carried out to achieve better water removal effect on the copper tube of the evaporator.

[0048] in, The first estimated pipe temperature when the anti-corrosion mode was last exited. The second estimated pipe temperature when the anti-corrosion mode was last exited. The estimated protection pipe temperature when the anti-corrosion mode was last exited. Specifically, the preset revision pipe temperature in this embodiment is is 1℃.

[0049] Therefore, in the process of controlling the air conditioner to execute the anti-corrosion mode by the air conditioner adaptive anti-corrosion control method of this embodiment, when the air conditioner executes the first over-temperature protection mode to shut down, and then restarts to control the air conditioner to execute the heating mode, the first budget pipe temperature is adjusted. , the second estimated pipe temperature is and budget protection pipe temperature An increase revision is made to increase the budgeted pipe temperature conditions, thereby avoiding frequent over-temperature protection of the air conditioner during the execution of the anti-corrosion mode, which affects the optimal water removal effect.

[0050] In one embodiment, when the air conditioner adaptive anti-corrosion control method of this embodiment meets the preset exit condition: the number of times the air conditioner executes the over-temperature protection mode reaches the preset number of times to exit the previous anti-corrosion mode, and when the air conditioner executes the next anti-corrosion mode, it is determined that the current first budget pipe temperature Is it the first preset upper limit temperature? If so, keep the current first budget pipe temperature If not, revise the first budget pipe temperature to ; And judge the current second budget pipe temperature is Is it the second preset upper limit temperature? If so, keep the current second budget pipe temperature as If not, revise the second budget pipe temperature to ; And determine the current budget protection pipe temperature Is it the third preset upper limit temperature? If so, keep the current budget protection pipe temperature If not, revise the estimated protection pipe temperature to ; Afterwards, the real-time tube temperature Compare with the budgeted pipe temperature conditions to control the working status of the indoor fan and indoor air guide plate, and revise the heating operation frequency of the compressor, that is, execute Figure 2 The relevant steps in the process are carried out to achieve better water removal effect on the copper tube of the evaporator.

[0051] in, The first estimated pipe temperature when the anti-corrosion mode was last exited. The second estimated pipe temperature when the anti-corrosion mode was last exited. The estimated protection pipe temperature when the anti-corrosion mode was last exited. Specifically, the preset revision pipe temperature in this embodiment is is 1℃.

[0052] Therefore, since the last exit of the anti-corrosion mode is due to the satisfaction of condition (three) in the preset exit condition of this embodiment: the number of times the air conditioner executes the over-temperature protection mode reaches the preset number, it means that the first budget pipe temperature of the last anti-corrosion mode has reached the preset number. , the second estimated pipe temperature is and budget protection pipe temperature The temperature value of the first budget pipe is small, which causes the air conditioner to frequently appear over-temperature protection during the last anti-corrosion mode and affects the optimality of the water removal effect. When the air conditioner executes the next anti-corrosion mode, the first budget pipe temperature is set to , the second estimated pipe temperature is and budget protection pipe temperature An increase revision is made to increase the budgeted pipe temperature conditions, thereby avoiding frequent over-temperature protection of the air conditioner during the execution of the anti-corrosion mode, which affects the optimal water removal effect.

[0053] Furthermore, the air conditioning adaptive anti-corrosion control method of this embodiment is pre-set with an initial preset operating frequency , first preset temperature , second preset temperature and preset protection temperature , so that when the air conditioner is controlled to execute the anti-corrosion mode, the number of execution times is For the first time, it is determined that When the compressor is controlled to run at the initial preset frequency Run, and at this time The first preset temperature ; Make sure to meet When the compressor is controlled to run at the initial preset frequency Run, and at this time The first preset temperature ,at this time The second initial preset temperature ; Make sure to meet When the anti-corrosion mode is last exited, the heating frequency of the compressor is determined. Is it the preset lower limit frequency of the compressor? If so, the compressor is controlled to run at the preset lower limit frequency; if not, the compressor is controlled to run at the revised frequency. Operation, revision frequency ,in is the preset revision frequency. The initial preset operating frequency , and at this time The second initial preset temperature , The initial preset protection temperature Among them, the initial preset operating frequency , first preset temperature , second preset temperature and preset protection temperature The corresponding setting can be made according to the relevant performance and usage conditions of the air conditioner. Preferably, the initial preset operating frequency of this embodiment is The initial first preset temperature is between 40HZ and 60HZ The initial second preset temperature is 56°C The initial preset protection temperature is 58°C is 60℃.

[0054] Therefore, the air conditioning adaptive anti-corrosion control method of this embodiment is to set the initial preset operating frequency , first preset temperature , second preset temperature and preset protection temperature Based on the revision, the air conditioning adaptive anti-corrosion control method of this embodiment can adaptively and continuously revise the heating operation frequency of the compressor, the first budget pipe temperature , Second budget pipe temperature and budget protection pipe temperature , so that the air conditioner can execute the anti-corrosion mode gradually closer to a better state, so as to achieve a better water removal effect on the copper tube of the evaporator, thereby achieving a better anti-corrosion effect on the copper tube of the evaporator, thereby extending the service life of the air conditioner.
