Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention and are not to be construed as limiting the present invention.
A control method of an air conditioner according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1 to 9.
As shown in fig. 1, the air conditioner according to the embodiment of the present invention includes a compressor 501, an evaporator 503, a condenser 502, and an expansion valve 504. The compressor 501 is connected to the evaporator 503 and the condenser 502, the expansion valve 504 is connected between the evaporator 503 and the condenser 502, specifically, the suction pipe of the compressor 501 is connected to the evaporator 503, and the exhaust pipe 5011 of the compressor 501 is connected to the condenser 502.
In the embodiment where the air conditioner includes an indoor air conditioner and an outdoor air conditioner, the compressor 501 and the condenser 502 are located on the outdoor side, and the evaporator 503 and the expansion valve 504 are located on the indoor side; in the embodiment where the air conditioner is a complete machine, the compressor 501, the evaporator 503, the condenser 502, and the expansion valve 504 may all be disposed in the same space.
The control method of the air conditioner comprises the following steps:
s1: detecting the real-time temperature of the exhaust pipe; in this embodiment, a first temperature sensor may be disposed on the exhaust pipe, and the first temperature sensor is used to detect the exhaust temperature of the compressor, that is, detect the real-time temperature of the exhaust pipe.
S2: calculating a temperature change parameter of the exhaust pipe within a first preset time;
specifically, the temperature T1 of the exhaust pipe 5011 detected by the first temperature sensor 11 on the exhaust pipe 5011 may be collected after the air conditioner is operated for a first time T1, and the temperature T2 of the exhaust pipe 5011 detected by the first temperature sensor 11 on the exhaust pipe 5011 may be collected again after the air conditioner is operated for a second time T2.
The temperature change parameter may be a temperature change amount or a temperature change rate. For example, the temperature change Δ T1 in the first preset time Δ T1 (the first time T1 to the second time T2) may be calculated as T2-T1, or the temperature change rate Δ T1/Δ T1 in the first preset time may be calculated. Wherein, the first time t1 may be 1min to 4min.
S3: and determining the running state of the air conditioner according to the temperature change parameters of the exhaust pipe.
According to the control method of the air conditioner, the real-time temperature of the exhaust pipe of the compressor is detected, the operation state of the air conditioner is determined according to the temperature change parameter of the exhaust pipe, whether the air conditioner operates normally can be quickly discriminated, and the subsequent control steps are carried out according to the operation state, so that the use reliability of the air conditioner is improved.
Specifically, as shown in fig. 1 and 2, at the temperature variation parameter is greater than or equal to a first threshold value; determining normal operation of the air conditioner; and when the temperature change parameter is smaller than a first threshold value, determining the suction and exhaust state of the compressor.
That is, after the air conditioner is started, if the temperature rise of the exhaust pipe 5011 reaches a certain value, it may be determined that the air conditioner is in a normal operation state at this time, and if the temperature rise of the exhaust pipe 5011 does not reach a certain value, the air conditioner may be in a normal operation state, and it may also be that the compressor 501 is abnormal or failed, so that subsequent steps are required to further determine the suction and exhaust state of the compressor 501, that is, determine whether the compressor 501 is working normally, and ensure the reliability of the use of the compressor 501.
For convenience of understanding, the temperature change parameter may be set as the temperature change amount for explanation, and correspondingly, the first threshold may be 0 ℃ to 2 ℃, for example, the first threshold may be 1 ℃, 1.5 ℃, 2 ℃, and the like. Taking the first threshold value as 1 ℃, if the calculated temperature variation of the exhaust pipe 5011 is greater than or equal to 1 ℃, it is determined that the air conditioner is normally operated, and if the calculated temperature variation of the exhaust pipe 5011 is less than 1 ℃, the subsequent steps are required to determine the suction/exhaust state of the compressor 501.
As shown in fig. 3, step S3 includes:
s31: detecting the real-time temperature of a condenser coil; wherein, can set up second temperature sensor on the condenser coil, utilize this second temperature sensor to detect the real-time temperature of condenser coil.
S32: calculating the temperature change parameter of the condenser coil in the second preset time;
s33: and determining the suction and exhaust state of the compressor according to the temperature change parameters of the condenser coil.
The working state of the compressor 501 is determined according to the temperature change parameter of the coil pipe of the condenser 502 in the second preset time, whether the compressor 501 normally operates can be quickly discriminated, and the subsequent control steps are carried out according to the working state of the compressor 501, if the compressor 501 does not suck and exhaust air, the normal operation of the compressor 501 is proved, the compressor 501 needs to be shut down and maintained, if the compressor 501 can normally suck and exhaust air, whether other parts break down needs to be further checked, so that the compressor 501 can be prevented from being frequently started and stopped, and the use reliability of the compressor 501 is improved.
Specifically, step S22 includes: when the temperature change parameter is smaller than or equal to a second threshold value, determining that the compressor does not suck or exhaust air; and determining that the compressor has air suction and exhaust when the temperature change parameter is greater than a second threshold value.
That is to say, after the air conditioner is started, if the temperature rise of the coil of the condenser 502 reaches a certain value, it can be determined that the compressor 501 can normally suck and exhaust air, at this time, the compressor 501 is in a normal operation state, it is necessary to further investigate whether other components are in failure, so that frequent start and stop of the compressor 501 can be avoided, which is beneficial to improving the reliability of the compressor 501, if the temperature rise of the coil of the condenser 502 does not reach a certain value, that is, the temperature of the coil of the condenser 502 does not obviously rise, it is proved that the compressor 501 does not compress refrigerant into high-temperature and high-pressure gas, at this time, the compressor 501 may be abnormal or failed, and needs to be stopped and the compressor 501 needs to be maintained.
Specifically, after the third time T3 of the air conditioner operation, the temperature T3 detected by the second temperature sensor on the condenser coil may be collected, and after the fourth time T4 of the air conditioner operation, the temperature T4 detected by the second temperature sensor on the condenser coil may be collected again.
The temperature change parameter may be a temperature change amount or a temperature change rate. For example, the temperature change amount Δ T3 in the second preset time Δ T2 (the third time T3 to the fourth time T4) may be calculated as T4-T3, or the temperature change rate Δ T3/Δ T2 in the second preset time may be calculated.
For convenience of understanding, the temperature change parameter may be set as the temperature change amount for explanation, and correspondingly, the second threshold may be 5 ℃ to 10 ℃. Specifically, the second threshold may be 6 ℃, 8 ℃, 10 ℃, etc. Taking the second threshold value as 6 ℃ as an example, if the temperature variation parameter of the coil of the condenser 502 within the second preset time is calculated to be less than or equal to 6 ℃, it is determined that the compressor 501 does not normally suck and exhaust air, that is, the compressor 501 is abnormal or failed, and if the temperature variation parameter of the coil of the condenser 502 within the second preset time is calculated to be greater than 6 ℃, it is determined that the compressor 501 normally sucks and exhausts air and the compressor 501 is not abnormal or failed.
In some embodiments, if the compressor does not suck or exhaust air, the air conditioner may be further controlled to send a first prompt signal, for example, a user may be reminded of stopping the machine and performing maintenance on the compressor, and the user may obtain a fault type through the prompt of the air conditioner, thereby facilitating after-sales processing and troubleshooting.
As shown in fig. 4, in some embodiments, in step S3: if the air suction and exhaust of the compressor are determined, the control method of the air conditioner further comprises the step S4: a use state of a first temperature sensor on an exhaust pipe is determined.
That is, after the system checks that the compressor 501 is not abnormal or malfunctioning, it is necessary to determine the use state of the first temperature sensor 11 on the exhaust pipe 5011, thereby checking whether the first temperature sensor 11 on the exhaust pipe 5011 is damaged or loosened.
In examining the usage status of the first temperature sensor 11 on the exhaust pipe 5011, the usage status of the first temperature sensor 11 can be determined by calculating the difference between the real-time temperature of the exhaust pipe 5011 and the real-time temperature of the coil of the condenser 502, and according to the difference between the real-time temperature of the exhaust pipe 5011 detected by the first temperature sensor 11 and the real-time temperature of the coil of the condenser 502 detected by the second temperature sensor 12.
As shown in fig. 4 and 5, in some specific examples, step S4 includes:
when the difference is greater than or equal to a third threshold value, controlling the air conditioner to normally operate, wherein the third threshold value can be 2-6 ℃; and determining that the using state of the first temperature sensor is abnormal when the difference value is smaller than a third threshold value.
Specifically, after the air conditioner is started, if a difference between a real-time temperature of the exhaust pipe 5011 detected by the first temperature sensor 11 and a real-time temperature of the coil of the condenser 502 detected by the second temperature sensor 12 reaches a certain value, it may be determined that the air conditioner is in a normal operation state, and if a difference between the real-time temperature of the exhaust pipe 5011 detected by the first temperature sensor 11 and the real-time temperature of the coil of the condenser 502 detected by the second temperature sensor 12 does not reach a certain value, it may be determined that the first temperature sensor 11 on the exhaust pipe 5011 is abnormal, for example, an electrical component of the first temperature sensor 11 may be damaged, or the first temperature sensor 11 may be released, so that the first temperature sensor 11 may not accurately detect the real-time temperature of the exhaust pipe 5011.
That is, when the temperature of the condenser 502 is normally raised, if the temperature of the exhaust pipe 5011 detected by the first temperature sensor 11 is lower than the temperature of the coil of the condenser 502, it indicates that the first temperature sensor 11 on the exhaust pipe 5011 is abnormal, and may be loose and unable to accurately sense the temperature, or the temperature sensing component of the first temperature sensor 11 is failed, and further troubleshooting is required.
Specifically, the third threshold may be 3 ℃, 4 ℃, 6 ℃, or the like. Taking the third threshold value as 4 ℃ as an example, if the difference between the real-time temperature of the exhaust pipe 5011 and the real-time temperature of the coil of the condenser 502 is calculated to be greater than or equal to 4 ℃, it is determined that the air conditioner is in a normal operation state, and if the difference between the real-time temperature of the exhaust pipe 5011 and the real-time temperature of the coil of the condenser 502 is calculated to be less than 4 ℃, it is determined that the first temperature sensor 11 is abnormal.
In step S4, if the first temperature sensor 11 is damaged, the air conditioner is further controlled to send a second prompt signal, for example, the user may be prompted to stop the machine and replace or repair the first temperature sensor 11, and the user may obtain a fault type through the prompt of the air conditioner, which is convenient for after-sales processing and troubleshooting.
As shown in fig. 6, in some embodiments, in step S4, if the usage state of the first temperature sensor is abnormal, then step S5 is further included: and detecting working parameters of the first temperature sensor, and determining whether the first temperature sensor is damaged or not according to the working parameters of the first temperature sensor.
The working parameter may be a voltage value of the first temperature sensor 11, or a resistance value of the first temperature sensor 11, and the use state of the first temperature sensor 11 may be further determined by the detected working parameter of the first temperature sensor 11, so as to implement troubleshooting, and improve the use reliability of the air conditioner.
As shown in fig. 6 and 7, in some examples, step S5 includes:
and when the working parameter does not satisfy a fourth threshold, determining that the first temperature sensor 11 is damaged, where the working parameter may be a voltage of the first temperature sensor 11 or a resistance of the first temperature sensor 11, and when the working parameter is a resistance, the fourth threshold may be 1.5V to 2.5V.
And when the working parameter meets a fourth threshold value, calculating the difference value between the top temperature of the compressor and the real-time temperature of the exhaust pipe, and determining the running state of the air conditioner according to the difference value between the top temperature of the compressor and the real-time temperature of the exhaust pipe.
Note that, if the first temperature sensor 11 in the exhaust pipe 5011 is damaged, the resistance value thereof is 0 or infinity, and the voltage value of the first temperature sensor 11 also inevitably exceeds the normal range at this time.
Taking the operating parameter as the voltage value of the first temperature sensor 11 as an example, the fourth threshold may be 1.5V-2.5V, and the fourth threshold may be 2V or 2.5V. If the fourth threshold is 2V, it is determined that the first temperature sensor 11 on the exhaust pipe 5011 is failed if the detected voltage value of the first temperature sensor 11 exceeds 2V, and if the detected voltage value of the first temperature sensor 11 is less than 2V, the first temperature sensor 11 may be loosened or detached.
Because when the first temperature sensor 11 loosens, the first temperature sensor 11 can not accurately sense the temperature, the opening degree of the expansion valve 504 of the air conditioner is reduced, the exhaust temperature is increased, and the temperature controller of the upper cover of the compressor 501 is triggered to act, so that the compressor 501 is frequently started and stopped.
When the difference value is greater than a fifth threshold value, wherein the fifth threshold value can be 15-70 ℃, and the air conditioner is controlled to stop running; and when the difference value is less than or equal to a fifth threshold value, controlling the air conditioner to normally operate.
Specifically, the fifth threshold may be 20 ℃, 30 ℃, 60 ℃, 70 ℃, or the like. Taking the fifth threshold value of 30 ℃ as an example, if the difference between the top temperature of the compressor 501 and the real-time temperature of the exhaust pipe 5011 is less than or equal to 30 ℃, the air conditioner is controlled to be normally operated, and if the difference between the top temperature of the compressor 501 and the real-time temperature of the exhaust pipe 5011 is greater than 30 ℃, the air conditioner must be immediately stopped.
It should be noted that when the system has a limit condition such as leakage, ice blockage, or no valve opening, the motor of the compressor 501 will continuously generate heat, the temperature difference between the exhaust pipe 5011 and the casing of the compressor 501 will increase due to lack of heat transfer of the refrigerant, and if the first temperature sensor 11 on the exhaust pipe 5011 fails, the first temperature sensor 11 cannot accurately control the opening degree of the expansion valve 504 or perform high-temperature exhaust limiting, so that it is necessary to immediately stop the engine for protection.
And when the difference value is greater than a fifth threshold value, the air conditioner is controlled to send a third prompt signal, so that a user can obtain the fault type through the prompt of the air conditioner, and the after-sale treatment is convenient.
An air conditioner according to an embodiment of the second aspect of the present invention will be described with reference to fig. 1 to 9.
According to the air conditioner of the embodiment of the present invention, the control method of the air conditioner as described in the above embodiment is performed.
The control method of the air conditioner according to the embodiment of the invention has the beneficial technical effects, so the air conditioner according to the embodiment of the invention also has the technical effects, the real-time temperature of the exhaust pipe 5011 of the compressor 501 is detected, the operation state of the air conditioner is determined according to the temperature change parameter of the exhaust pipe 5011, whether the air conditioner normally operates can be quickly discriminated, and the subsequent control steps are carried out according to the operation state, so that the use reliability of the air conditioner is favorably improved.
As shown in fig. 8, in some embodiments, the air conditioner includes a compressor 501, an evaporator 503, a condenser 502, and an expansion valve 504. The compressor 501 is connected to the evaporator 503 and the condenser 502, the expansion valve 504 is connected between the evaporator 503 and the condenser 502, the suction pipe of the compressor 501 is connected to the evaporator 503, and the exhaust pipe 5011 of the compressor 501 is connected to the condenser 502.
In the present embodiment, the exhaust pipe 5011 is provided with a first temperature sensor 11 for detecting the exhaust temperature of the compressor 501, i.e., detecting the real-time temperature of the exhaust pipe 5011.
As shown in fig. 9, according to some embodiments of the present invention, the air conditioner includes a detection module 10, a calculation module 20 and a control module 30, the detection module 10 includes a first temperature sensor 11, the first temperature sensor 11 is disposed on an exhaust pipe 5011 of the compressor 501 for detecting a real-time temperature of the exhaust pipe 5011, the calculation module 20 is in communication with the first temperature sensor 11 on the exhaust pipe 5011 and the control module 30, the calculation module 20 is for calculating a temperature variation parameter of the exhaust pipe 5011 within a first preset time, and the control module 30 can determine an operation state of the air conditioner according to the temperature variation parameter of the exhaust pipe 5011 within the first preset time calculated by the calculation module 20.
According to the air conditioner provided by the embodiment of the invention, the real-time temperature of the exhaust pipe 5011 of the compressor 501 is detected by the first temperature sensor 11, the calculation module 20 is used for calculating the temperature change parameter of the exhaust pipe 5011 within the first preset time, and the control module 30 can determine the operation state of the air conditioner according to the calculation result of the calculation module 20, namely whether the air conditioner normally operates can be quickly discriminated, and the subsequent control steps are carried out according to the operation state, so that the use reliability of the air conditioner is favorably improved.
In some embodiments, the control module 30 determines that the air conditioner is normally operated when the temperature variation parameter of the exhaust pipe 5011 calculated by the calculation module 20 is greater than or equal to a first threshold value, thereby controlling the air conditioner to continue to operate, and the control module 30 determines the suction and exhaust state of the compressor 501 when the temperature variation parameter of the exhaust pipe 5011 calculated by the calculation module 20 is less than the first threshold value.
That is to say, after the air conditioner is started, if the temperature rise of the exhaust pipe 5011 calculated by the calculation module 20 reaches a certain value, the control module 30 may determine that the air conditioner is in a normal operation state at this time, so the air conditioner does not need to be stopped, and if the temperature rise of the exhaust pipe 5011 calculated by the calculation module 20 does not reach a certain value, the air conditioner may be in a normal operation state, and may also be that the compressor 501 is abnormal or has a fault, so subsequent steps need to be performed, so as to further determine the suction/exhaust state of the compressor 501, that is, determine whether the compressor 501 is working normally, and ensure the reliability of the use of the compressor 501.
In some embodiments, the detection module 10 further includes a second temperature sensor 12, the second temperature sensor 12 is in communication with the calculation module 20 and the control module 30, the calculation module 20 is further configured to calculate a temperature variation parameter of the coil of the condenser 502 within a second preset time, and the control module 30 determines the suction/discharge state of the compressor 501 according to the calculation result of the calculation module 20.
The control module 30 determines the working state of the compressor 501 according to the temperature change parameter of the coil of the condenser 502 in the second preset time, can quickly determine whether the compressor 501 normally operates, and performs subsequent control steps according to the working state of the compressor 501, if the compressor 501 does not perform air suction and exhaust, it is proved that the compressor 501 normally operates, the compressor 501 needs to be shut down and maintained, if the compressor 501 can perform air suction and exhaust normally, it is further required to investigate whether other components break down, so that frequent start and stop of the compressor 501 can be avoided, and the use reliability of the compressor 501 can be improved.
Specifically, if the temperature rise of the coil of the condenser 502 reaches a certain value, the control module 30 may determine that the compressor 501 can normally suck and exhaust air, and at this time, the compressor 501 is in a normal operation state, and it is necessary to further check whether other components are in failure, so that frequent start and stop of the compressor 501 may be avoided, which is beneficial to improving the reliability of the compressor 501 in use.
In some embodiments, the air conditioner further includes a first prompt module 41, the first prompt module 41 is in communication with the control module 30, after it is determined that the compressor 501 is not exhausted, the control module 30 controls the first prompt module 41 to send a first prompt signal, which can remind a user of stopping the air conditioner and repairing the compressor 501, and the user can obtain a fault type through the prompt of the air conditioner, thereby facilitating after-sales processing and troubleshooting.
According to some embodiments of the present invention, after the control module 30 determines that there is suction/discharge of the compressor 501, the calculation module 20 calculates a difference between a real-time temperature of the discharge pipe 5011 and a real-time temperature of the coil of the condenser 502, if the difference is greater than or equal to a third threshold, the control module 30 determines that the air conditioner is normally operated, and if the difference is less than the third threshold, the control module 30 determines that the usage state of the first temperature sensor 11 is abnormal.
That is, when the temperature of the condenser 502 is normally raised, if the temperature of the exhaust pipe 5011 detected by the first temperature sensor 11 is lower than the temperature of the coil of the condenser 502, it indicates that the first temperature sensor 11 on the exhaust pipe 5011 is abnormal, and may be loose and unable to accurately sense the temperature, or the temperature sensing component of the first temperature sensor 11 is failed, and further troubleshooting is required.
In some embodiments, the air conditioner further includes a second prompt module 42, the second prompt module 42 is in communication with the control module 30, after it is determined that the first temperature sensor 11 is damaged, the control module 30 controls the second prompt module 42 to send a second prompt signal, the user may prompt the user to stop the machine and replace or repair the first temperature sensor 11, and the user may obtain a fault type through the prompt of the air conditioner, so as to facilitate after-sales processing and troubleshooting.

Therefore, the operating parameter may be a voltage value of the first temperature sensor 11, and may also be a resistance value of the first temperature sensor 11.
After the abnormality of the first temperature sensor 11 occurs, the calculation module 20 further calculates a difference between the top temperature of the compressor 501 and the real-time temperature of the exhaust pipe 5011, and if the difference is greater than a fifth threshold, the control module 30 controls the air conditioner to stop operating, and if the difference is less than or equal to the fifth threshold, the control module 30 controls the air conditioner to normally operate.
In some embodiments, the air conditioner further includes a third prompting module 43, the third prompting module 43 is in communication with the control module 43, when the difference between the top temperature of the compressor 501 and the real-time temperature of the exhaust pipe 5011 is greater than a fifth threshold, the control module 30 controls the third prompting module 43 to send a third prompting signal, and the user can obtain the fault type through the prompting of the air conditioner, so as to facilitate the after-sales processing.
