Referring to fig. 1, an embodiment of the present disclosure provides a control method for an air conditioner, including:
s101, under the condition that a compressor of the air conditioner continuously operates for a first preset time, detecting a temperature parameter of the air conditioner and the total current of an outdoor unit of the air conditioner by a detection element; wherein the temperature parameter comprises one or more.
In the embodiment of the disclosure, after the compressor of the air conditioner continuously operates for the first preset time, the detection of the relevant parameters is started. Here, the minimum value of the first preset time period is 3 minutes. Because the compressor starts the initial stage, the system operation is unstable, and relevant parameter fluctuation is great. Therefore, after the compressor runs for a period of time, the parameters are detected. The temperature parameter of the air conditioner is detected by a temperature sensor provided on the air conditioner, and the total current of the outdoor unit is detected by a current detecting means such as a current detecting sensor. The temperature parameters of the air conditioner comprise one or more of the indoor unit coil temperature, the outdoor unit coil temperature, the compressor exhaust temperature and the like. The total current of the outdoor unit includes the total current of the compressor, the motor, the control panel, the valve and other components of the outdoor unit.
And S102, the processor determines a preset condition corresponding to the temperature parameter according to the running mode of the air conditioner.
In the embodiment of the disclosure, the air conditioner is in different operation modes, and the preset conditions for judging whether the stop valve is opened or not are different. Here, the operation mode mainly refers to a heating mode or a cooling mode. The description will be given by taking the example in which the detected temperature includes the indoor coil temperature. In the cooling mode, the preset condition corresponding to the temperature of the indoor coil pipe is that the difference value between the temperature of the indoor coil pipe and the temperature of the indoor environment is larger than a first threshold value. In the heating mode, the preset condition corresponding to the indoor coil temperature is that the difference value between the indoor coil temperature and the indoor environment temperature is greater than a second threshold value. The second threshold is larger than the first threshold, the value range of the first threshold is a negative value, and the value of the second threshold is a positive value. When the air conditioner is used for refrigerating, the temperature of the indoor coil is lower than the indoor environment temperature. When the air conditioner heats, the temperature of the indoor coil is higher than the indoor environment temperature. Therefore, the preset conditions corresponding to the detected temperature parameters are different in different operation modes. Thus, the method is beneficial to combining with the operation mode and accurately setting the preset condition, thereby improving the judgment accuracy.
S103, the processor controls the compressor to stop when any temperature parameter meets the corresponding preset condition and the total current is greater than the current threshold value.
Here, the current threshold value has a corresponding relationship with the operating frequency of the compressor and the cooling capacity of the air conditioner, and the current threshold value can be determined by acquiring the operating frequency of the compressor and the cooling capacity of the air conditioner. The operating frequency of the compressor is the operating frequency of the compressor after the compressor is started for a period of time. Further, the current threshold may be set differently for different modes of operation of the air conditioner. When the stop valve of the refrigerant is not opened, the refrigerant cannot be effectively circulated, and the indoor temperature cannot reach the target temperature. The air conditioner increases the power of the compressor, and thus, the total current of the outdoor unit is increased. And under the condition that the total current of the outdoor unit is greater than the current threshold value and any detected temperature parameter meets the corresponding preset condition, determining that the stop valve is not opened, and controlling the compressor to stop. Thereby avoiding the risk of damage or explosion of the compressor during long-time operation.
By adopting the control method for the air conditioner provided by the embodiment of the disclosure, the temperature parameter of the air conditioner and the total current of the outdoor unit are detected after the compressor of the air conditioner continuously operates for a period of time. And determining and judging the preset condition of compressor shutdown protection according to the operation mode of the air conditioner. And controlling the compressor to stop under the condition that any detected temperature parameter meets the corresponding preset condition and the total current is greater than the current threshold value. Thus, different preset conditions are set for different operation modes of the air conditioner. The accuracy and the reliability of judging the preset conditions are improved.
Optionally, in step S101, the detecting element detects a temperature parameter of the air conditioner, including: the temperature of the coil of the indoor unit is detected, and/or the suction temperature of the compressor is detected, and/or the temperature of the coil of the outdoor unit and the temperature of the liquid outlet end of the outdoor heat exchanger are detected.
In the embodiment of the disclosure, the temperature parameter for detecting the air conditioner includes one or more of the temperature of the indoor unit coil, the suction temperature of the compressor, the temperature of the outdoor unit coil and the temperature of the liquid outlet end of the outdoor heat exchanger. The indoor unit coil temperature, the outdoor unit coil temperature and the compressor suction temperature are all related to the refrigerant flow. Therefore, the temperature parameter of the air conditioner mainly refers to the temperature of a component or a position related to the refrigerant flow rate. Further, it is understood that, when the detected temperature parameter includes only one, the compressor is controlled to stop when the detected temperature parameter satisfies a preset condition and the total current is greater than the current threshold. When the detected temperature parameters include multiple types, whether the multiple temperature parameters meet corresponding preset conditions or not can be judged simultaneously, and when any one temperature parameter meets the corresponding preset conditions and the total current meets the conditions, the compressor is controlled to stop. Alternatively, the plurality of temperature parameters can be judged according to certain nesting logic.
As an example, the sensed temperature parameters include a temperature of an indoor unit coil, a suction temperature of a compressor. The nesting logic is to judge whether the air suction temperature meets the preset condition or not under the condition that the total current meets the condition, and if so, the compressor is controlled to stop. If the air suction temperature does not meet the corresponding preset conditions, the temperature of the coil pipe of the indoor unit is further judged, and the compressor is controlled to stop under the condition that the temperature of the coil pipe of the indoor unit meets the corresponding preset conditions. And if the temperature of the coil pipe of the indoor unit does not meet the corresponding preset condition, judging again. Here, in the nested control logic, the determination order of the detection parameters is set to be total current determination, suction temperature determination, indoor unit coil temperature, and outdoor unit coil temperature in order from high to low. The coil temperature of the indoor unit and the coil temperature of the outdoor unit are not in sequence. Therefore, the on-off state of the stop valve can be judged by detecting a plurality of parameters and setting a plurality of judgment conditions, so that the condition that the single sensor fails or the detection is inaccurate to cause the misjudgment is avoided. Compared with a single sensor, the method is beneficial to improving the safety and reliability of judgment.
Optionally, in step S102, the processor determines a preset condition corresponding to the temperature parameter according to the operation mode of the air conditioner, where the preset condition includes:
under the condition that the air conditioner operates in the cooling mode, the processor determines that the corresponding preset condition comprises the following steps: temperature T of indoor unit coil pipemWith the current indoor ambient temperature TaiIs greater than or equal to a first temperature threshold T1(ii) a And/or the suction temperature T of the compressorsGreater than a second temperature threshold T2(ii) a And/or outdoor unit coil temperature TcmTemperature T of liquid outlet end of outdoor heat exchangereIs less than or equal to the current outdoor ambient temperature Tao。
In the embodiment of the disclosure, in the cooling mode, a corresponding preset condition is set for each detected temperature parameter. Here, the first temperature threshold T1Values are negative, for example-2 ℃. When the air conditioner operates normally, the temperature of the coil pipe of the indoor unit is far lower than the current indoor environment temperature. Therefore, under the condition that the temperature of the coil pipe of the indoor unit is not greatly different from the current indoor environment temperature, the stop valve can be judged not to be opened. The second temperature threshold value is 20-30 ℃, and the value can be 30 ℃. Wherein, when the air conditioner normally runs in a cooling mode, the air suction temperature depends on the outdoor environment temperature and the exhaust temperature. When the stop valve is not opened, the exhaust temperature of the compressor is increased due to the increase of the power of the compressor, so that the suction temperature is continuously increased. The second temperature threshold value therefore has a value range which is higher than the suction temperature of the compressor during normal operation. In addition, the maximum value of the outdoor unit coil temperature and the outdoor heat exchanger liquid outlet end temperature is taken, namely max (T)cm，Te) And comparing the maximum value of the two with the current outdoor environment temperature. The temperature of the liquid outlet end of the outdoor heat exchanger refers to the surface temperature of a certain branch in a liquid outlet pipeline of the outdoor heat exchanger. The temperature of the coil pipe of the outdoor unit under the normal operation state of the air conditionerIs higher than the temperature of the liquid outlet end of the outdoor heat exchanger. However, in this embodiment, if the maximum value of the two is still less than or equal to the current outdoor ambient temperature, it indicates that the refrigerant in the pipeline is insufficient to flow, and it can be determined that the stop valve is not opened.
Optionally, in step S102, the processor determines a preset condition corresponding to the temperature parameter according to the operation mode of the air conditioner, where the preset condition includes:
under the condition that the air conditioner runs in the heating mode, the processor determines the corresponding preset conditions to comprise the following steps: temperature T of indoor unit coil pipemWith the current indoor ambient temperature TaiIs greater than or equal to a third temperature threshold T3(ii) a And/or the suction temperature T of the compressorsGreater than a fourth temperature threshold T4(ii) a And/or outdoor unit coil temperature TcmTemperature T of liquid outlet end of outdoor heat exchangereMaximum value of and current outdoor ambient temperature TaoIs greater than or equal to a preset threshold.
In the embodiment of the present disclosure, the third temperature threshold value is a positive value, for example, 3 ℃. Wherein an absolute value of the third temperature threshold may be equal to an absolute value of the first temperature threshold. The fourth temperature threshold may be equal to or less than the second temperature threshold, where the fourth temperature threshold ranges from 28 to 35 ℃ because the suction temperature in the heating mode is higher than that in the cooling mode. In addition, the preset threshold value range is 0-3 ℃. At max (T)cm，Te) When the difference value with the current outdoor replacement temperature is smaller, the refrigerant in the pipeline is insufficient to circulate, and the stop valve can be judged not to be opened.
Optionally, the temperature parameter includes a temperature of the coil of the indoor unit, and/or a temperature of the coil of the outdoor unit and a temperature of the liquid outlet end of the outdoor heat exchanger; step S103, the processor determines that any one of the temperature parameters satisfies the corresponding preset condition by the following means:
and in a plurality of detection periods or within a second preset time length, the temperature of the coil pipe of the indoor unit, or the temperature of the coil pipe of the outdoor unit and the temperature of the liquid outlet end of the outdoor heat exchanger meet corresponding preset conditions, and the temperature parameter is determined to meet the corresponding preset conditions.
In the disclosed embodiments, toAnd determining that the temperature parameter meets the preset condition under the condition that the temperature parameter comprises the temperature of the coil pipe of the indoor unit, or the temperature of the coil pipe of the outdoor unit and the temperature of the liquid outlet end of the outdoor heat exchanger, or both the temperature parameter and the temperature of the liquid outlet end of the outdoor heat exchanger. The temperature parameters of the air conditioner are influenced by various factors, such as the repeated start-stop of the air conditioner, and particularly the temperature of a coil. In order to ensure the stability of the temperature detection of the indoor and outdoor coils, a plurality of detection periods or a second preset time length is set. As an example, the second preset time period is 1 minute, taking the temperature of the coil of the indoor unit as an example. When the temperature of the coil pipe of the indoor unit is continuously satisfied within 1 minute, Tm-Tai≥T1Or Tm-Tai≥T3And the temperature of the coil pipe of the indoor unit meets the corresponding preset conditions. As another example, the plurality of sensing periods includes 3 sensing periods. The three detection periods may be continuous detection periods or discontinuous detection periods. When the detection period is discontinuous, the interval time is not suitable to be too long; the three detection periods may be limited to three detection periods within 1 hour. Still taking the coil temperature of the indoor unit as an example, if within a limited time period, T times are detected for 3 timesm-Tai≥T1Or Tm-Tai≥T3And the temperature of the coil pipe of the indoor unit meets the corresponding preset condition. Therefore, misjudgment caused by disturbance or other factors can be effectively reduced, and the reliability and accuracy of judgment are improved.
In addition, the factors of the over-high exhaust temperature of the compressor are clear, and mainly include the blockage and reverse rotation of the compressor, the insufficient effective circulation of the refrigerant and the like. Here, excessive restrictions are not set on the judgment of whether the compressor discharge temperature satisfies the corresponding preset conditions; in order to protect the compressor better, when the exhaust temperature of the compressor is too high, namely the preset condition is determined to be met, the compressor is controlled to stop.
Referring to fig. 2, an embodiment of the present disclosure provides another control method for an air conditioner, including:
s201, detecting a temperature parameter of the air conditioner by a detection element under the condition that the air conditioner is powered on for the first time, and the running time of a compressor is longer than a first preset time and shorter than a time threshold; the temperature parameter comprises the temperature of the coil pipe of the indoor unit, and/or the temperature of the coil pipe of the outdoor unit and the temperature of the liquid outlet end of the outdoor heat exchanger; and detecting the total current of the outdoor unit under the condition that the running time of the compressor is longer than a first preset time.
S202, the processor determines preset conditions corresponding to temperature parameters according to the operation mode of the air conditioner;
s203, the processor controls the compressor to stop when any temperature parameter meets the corresponding preset condition and the total current is greater than the current threshold value.
In the embodiment of the disclosure, under the condition that the detected temperature parameter includes the temperature of the coil of the indoor unit and/or the temperature of the coil of the outdoor unit, the detection time is limited. Here, the detection is performed only in a case where the air conditioner is powered on for the first time, the compressor is continuously operated for a first preset time period, and the operation time period is less than a time threshold. In one aspect, the check valve is substantially determined to be open when the compressor has been operating for a time period greater than or equal to the time threshold, the compressor being in a normal operating condition. Therefore, it is not necessary to continue detecting the temperature parameter. On the other hand, when the air conditioner leaves the factory, the refrigerant is sealed in order to ensure the safety of the refrigerant, and after the air conditioner is electrified for the first time, the refrigerant stop valve is not opened. In addition, the compressor should not open for a long time when refrigerant stop valve is not opened yet, has the safety risk. The time threshold may range from 50 to 70 minutes.
Referring to fig. 3, an embodiment of the present disclosure provides another control method for an air conditioner, including:
s301, under the condition that a compressor of the air conditioner continuously operates for a first preset time, detecting a temperature parameter of the air conditioner and the total current of an outdoor unit of the air conditioner by a detection element; wherein the temperature parameter comprises one or more.
And S302, the processor determines a preset condition corresponding to the temperature parameter according to the operation mode of the air conditioner.
And S303, controlling the compressor to stop when any temperature parameter meets the corresponding preset condition and the total current is greater than the current threshold value by the processor.
S304, the processor controls the compressor to resume running after the compressor is stopped for a third preset time; and under the condition that the interval time of two adjacent stoppages is less than a fourth preset time, the compressor is not controlled to resume running any more.
In the embodiment of the disclosure, after the preset condition is met and the compressor is controlled to stop for a third preset time, the compressor is controlled to resume running. Here, the third preset time period ranges from 3 to 10 minutes. And continuously detecting the related parameters after the operation is recovered, and controlling the compressor to stop again if the detected parameters accord with the stop control again. Meanwhile, the interval duration of two stop operations is obtained, if the interval duration is short, the stop valve is determined not to be opened, and fault information is output. In this case, the compressor does not need to be controlled again to resume operation. Here, the fourth preset time period may take a value of 30 minutes.
Referring to fig. 4, an embodiment of the present disclosure provides another control method for an air conditioner, including:
s401, under the condition that a compressor of the air conditioner continuously operates for a first preset time, detecting a temperature parameter of the air conditioner and the total current of an outdoor unit of the air conditioner by a detection element; wherein the temperature parameter comprises one or more.
S402, the processor determines preset conditions corresponding to the temperature parameters according to the operation mode of the air conditioner.
And S403, under the condition that the temperature parameters comprise a plurality of temperature parameters, the processor determines whether the temperature parameters meet corresponding preset conditions according to a preset sequence.
S404, the processor controls the compressor to stop if any temperature parameter meets a preset condition under the condition that the total current is larger than the current threshold.
In the disclosed embodiment, the inspection parameters include a temperature parameter and a current parameter; the current parameter, i.e. the total current, is determined first. And judging the temperature parameter again under the condition that the total current is greater than the current threshold value. And if any temperature parameter meets the corresponding preset condition, controlling the compressor to stop. Further, when the temperature parameters include a plurality of temperature parameters, whether the temperature parameters meet corresponding preset conditions is determined according to a preset sequence. Specifically, the temperature parameters include the temperature of the coil of the indoor unit, the suction temperature of the compressor, the temperature of the coil of the outdoor unit and the temperature of the liquid outlet end of the outdoor heat exchanger. The preset sequence is the suction temperature of the compressor, the temperature of the coil pipe of the indoor unit, the temperature of the coil pipe of the outdoor unit and the temperature of the liquid outlet end of the outdoor heat exchanger from high to low. Namely, whether the suction temperature of the compressor meets the corresponding preset condition is judged, and if so, the compressor is controlled to stop. If not, judging the temperature of the coil pipe of the indoor unit; and finally, judging the temperature of the coil pipe of the outdoor unit and the temperature of the liquid outlet end of the outdoor heat exchanger. In addition, the temperature of the coil pipe of the indoor unit, the temperature of the coil pipe of the outdoor unit and the temperature of the liquid outlet end of the outdoor heat exchanger can be replaced mutually or not sequentially. Thus, the judgment is performed through the nested logic judgment sequence, and the possibility of misjudgment is reduced.
