However, in the actual construction process, there is a problem that: in the use process of the traditional air conditioner, whether the air conditioner is in a condensation water hanging state cannot be judged, so that condensation water drops on the ground to influence the use of a user.
Disclosure of Invention
The invention solves the technical problem that the air conditioner cannot judge whether the air outlet of the indoor unit has condensation, and achieves the technical effects of judging whether the air conditioner needs to be controlled to run for condensation prevention and controlling the air conditioner according to the judging result.
In order to solve the above problems, the present disclosure provides a control method for preventing condensation of an air conditioner, the control method comprising: in a refrigeration mode, acquiring operation parameters of an air conditioner, wherein the operation parameters of the air conditioner comprise indoor environment temperature, outdoor environment temperature and air outlet temperature of the air conditioner; judging whether the operation parameters of the air conditioner meet the anti-condensation conditions, and if so, controlling the air conditioner to enter an anti-condensation mode.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: the commonly used anti-condensation detection parameters comprise indoor and outdoor environment temperatures or only the temperature of an air outlet of an indoor unit, and the detection of the parameters cannot comprehensively and accurately judge whether condensation exists. In the scheme, three parameters including outdoor environment temperature, indoor environment temperature and air outlet temperature of an indoor unit are introduced, and the three parameters are combined to judge whether the air conditioner generates condensation or not, so that whether the air conditioner generates condensation or not can be judged, and compared with other judging conditions, the judging method provided by the scheme is more accurate. In addition, in the scheme, besides judging whether the condensation is generated, the anti-condensation control method is further included, in the steps, after the judgment is finished, if the condensation exists, the air conditioner is directly controlled to enter an anti-condensation mode, so that the control method is more complete, and the problem of the generation of the condensation can be comprehensively and effectively solved and treated.
In one example of the present invention, determining whether the operation parameter of the air conditioner satisfies the anti-condensation condition specifically includes: judging whether the indoor environment temperature and/or the outdoor environment temperature meets the first condensation preventing condition; if so, judging whether the air outlet temperature of the air conditioner meets the second condensation preventing condition.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: two anti-condensation conditions are set, and the conditions are required to be met simultaneously, so that the judging process is more detailed and accurate, the accuracy of the judging result is improved, and the judging process is more efficient. In addition, in the two judging conditions, the first judging condition is a rough judging condition, the second anti-condensation condition is a more accurate judging condition, and the judging process is gradually progressed from rough to fine, so that the accuracy and the rationality of the judging process are ensured.
In one example of the present invention, determining whether the indoor environment temperature and/or the outdoor environment temperature satisfies the first condensation preventing condition specifically includes: judging whether the air conditioner operates for a first operation duration, and if so, meeting a first condensation preventing condition; the first operation duration is obtained according to the indoor environment temperature and/or the outdoor environment temperature.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: judging that the indoor and outdoor environment temperatures are inaccurate, controlling the air conditioner to run for a first running time for more accurate judgment, and after the first running time is passed, indicating that the air conditioner maintains the indoor and outdoor environment temperatures in the corresponding states for a period of time, so that the possibility of condensation is higher, and error judgment caused by larger fluctuation of the temperature is avoided. And the operation time length is selected according to the temperature range, so that the time can be saved more efficiently, whether the air conditioner generates condensation can be judged, the judgment time is reasonably planned, and the judgment is accurate, and meanwhile, the time is saved more efficiently.
In one example of the present invention, the first operation duration is obtained according to the indoor environment temperature and/or the outdoor environment temperature, and specifically includes: determining a range of a first operation duration according to the indoor environment temperature and the indoor environment temperature threshold; and/or determining the first operation duration according to the outdoor environment temperature and the outdoor environment temperature threshold value; wherein the first operating duration is proportional to the outdoor ambient temperature and inversely proportional to the indoor ambient temperature.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: the operation time length is selected according to the temperature range, so that the time can be saved more efficiently, whether the air conditioner generates condensation can be judged, the judgment time is reasonably planned, and the judgment is accurate, and meanwhile, the time is more efficient and saved. Specifically, the magnitude of the operation time length is related to the indoor environment temperature and the outdoor environment temperature, so that the numerical selection of the operation time length can be more accurately and reasonably obtained. When the outdoor environment temperature is higher, the air conditioner is not easy to form condensation, and can be operated for a longer time to judge, so that the outdoor environment temperature is in direct proportion to the operation time; the air conditioner is more likely to form condensation when the indoor ambient temperature is higher, and thus the operation time should be shorter, and thus the indoor ambient temperature is inversely proportional to the operation time period.
In one example of the present invention, when the indoor ambient temperature is greater than the first indoor ambient temperature threshold and the outdoor ambient temperature is greater than the first outdoor ambient temperature threshold, the first operation duration is determined to be H 3 The method comprises the steps of carrying out a first treatment on the surface of the When the indoor environment temperature is greater than the first indoor environment temperature threshold value and the outdoor environment temperature is less than the first outdoor environment temperature threshold value, and the outdoor environment temperature is greater than the second outdoor environment temperature threshold value, determining that the first operation duration is H 2 The method comprises the steps of carrying out a first treatment on the surface of the When the indoor environment temperature is greater than the first indoor environment temperature threshold value and the outdoor environment temperature is less than the second outdoor environment temperature threshold value, determining that the first operation duration is H 1 The method comprises the steps of carrying out a first treatment on the surface of the When the indoor environment temperature is smaller than the first indoor environment temperature threshold and larger than the second indoor environment temperature threshold and the outdoor environment temperature is larger than the first outdoor environment temperature threshold, determining that the first operation duration is H 4 The method comprises the steps of carrying out a first treatment on the surface of the When the indoor environment temperature is smaller than the first indoor environment temperature threshold and larger than the second indoor environment temperature threshold, and the outdoor environment temperature is smaller than the first outdoor environment temperature threshold and larger than the second outdoor environment temperature threshold, determining that the first operation duration is H 3 The method comprises the steps of carrying out a first treatment on the surface of the When the indoor environment temperature is smaller than the first indoor environment temperature threshold and larger than the second indoor environment temperature threshold, and the outdoor environment temperature is smaller than the second outdoor environment temperature threshold, determining that the first operation duration is H 2 The method comprises the steps of carrying out a first treatment on the surface of the When the indoor environment temperature is smaller than the second indoor environment temperature threshold value and the outdoor environment temperature is larger than the first outdoor environment temperature threshold value, determining that the first operation duration is H 5 The method comprises the steps of carrying out a first treatment on the surface of the When the indoor environment temperature is smaller than the second indoor environment temperature threshold value and the outdoor environment temperature is smaller than the first outdoor environment temperature threshold value, the first operation duration is determined to be H when the outdoor environment temperature is larger than the second outdoor environment temperature threshold value 4 The method comprises the steps of carrying out a first treatment on the surface of the When the indoor environment temperature is smaller than the second indoor environment temperature threshold value and the outdoor environment temperature is smaller than the second outdoor environment temperature threshold value, determining that the first operation duration is H 3 The method comprises the steps of carrying out a first treatment on the surface of the Wherein the first indoor environment temperature threshold is greater than the second indoor environment temperature threshold, the first outdoor environment temperature threshold is greater than the second outdoor environment temperature threshold, and H 5 >H 4 >H 3 >H 2 >H 1 。
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: firstly, determining the range of the operation time length through the indoor environment temperature, and when the indoor environment temperature is higher, the maximum endpoint value of the range of the operation time length is higher, and correspondingly, the selectable value of the operation time length is longer. After the range is determined, a specific running time length value is determined according to the indoor environment temperature. The value of the operation time length is determined by at least two influencing factors, and the obtained result is accurate.
In one example of the present invention, determining whether the air conditioner outlet air temperature meets the second condensation preventing condition specifically includes: detecting the air outlet temperature of the air conditioner every first time period, and if the air outlet temperature meets the air outlet threshold value, meeting a second condensation preventing condition; the first time period is determined according to the first operation time, and the air outlet temperature threshold value is in direct proportion to the outdoor environment temperature.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: the first time interval is set to detect the air outlet temperature, so that inaccurate judgment results can be avoided when the air outlet temperature is changed, the air outlet temperature can be detected at a higher frequency, and the judgment results can be corrected in time according to the change of the air outlet temperature. The first time period is the frequency of detection, and when the first operating time is long, the condensation is not easy to generate, so that the frequency of detection can be lower, further, the detection interval time, namely the first time period can be longer, the first time period is selected according to the first operating time, the influence parameters are simple, the frequency of detection can be accurately determined according to the state of the air conditioner, and the detection method is simple and efficient.
In one example of the present invention, the air outlet temperature threshold is proportional to the outdoor ambient temperature, and specifically includes: when the outdoor environment temperature is greater than the first outdoor environment temperature threshold, the air outlet temperature threshold is T 1 The method comprises the steps of carrying out a first treatment on the surface of the When the outdoor environment temperature is smaller than the first outdoor environment temperature threshold and larger than the second outdoor environment temperature threshold, the air outlet temperature threshold is T 2 The method comprises the steps of carrying out a first treatment on the surface of the When the outdoor environment temperature is smaller than the second outdoor environment temperature threshold, the air outlet temperature threshold is T 3 The method comprises the steps of carrying out a first treatment on the surface of the Wherein the first outdoor environment temperature threshold is greater than the second outdoor environment temperature threshold, and T 1 >T 2 >T 3 。
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: when the outdoor environment temperature is higher, the corresponding air outlet temperature should be higher at the moment, condensation can be easily generated when the temperature is too low, and accordingly, the air outlet temperature threshold value is also higher. The selected air outlet temperature threshold is selected according to the outdoor environment temperature, so that the air outlet temperature threshold is more reasonable. .
In one example of the present invention, controlling an air conditioner to enter an anti-condensation mode specifically includes: and the air output of the indoor unit of the air conditioner is improved.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: the control method in the scheme controls and improves the main problems, has strong pertinence and higher efficiency for solving the problems.

The lifting amplitude of the rotating speed of the indoor fan is adjusted according to the outdoor environment temperature, so that the rotating speed of the fan is prevented from being too high and exceeding a reasonable range.

Wherein, the aviation baffle is 45 angles in first rotation position, and the aviation baffle is 85 angles in second rotation position, and the aviation baffle is 120 angles in third rotation position, and the aviation baffle is 150 angles in fourth rotation position, and the aviation baffle is 180 angles in fifth rotation position, and the air output relation is: the air output of the third rotating position is larger than that of the fourth rotating position, the air output of the second rotating position is larger than that of the fifth rotating position, and the air output of the third rotating position is larger than that of the first rotating position.
Further, the specific control method in the scheme comprises the following steps:
step S100: in a refrigeration mode, acquiring operation parameters of an air conditioner, wherein the operation parameters of the air conditioner comprise indoor environment temperature, outdoor environment temperature and air outlet temperature of the air conditioner;
step S200: judging whether the operation parameters of the air conditioner meet the anti-condensation conditions, and if so, controlling the air conditioner to enter an anti-condensation mode.
In this embodiment, condensation generally occurs in a cooling mode of an air conditioner, and therefore, it is necessary to detect corresponding parameters in the cooling mode and determine whether to perform the condensation prevention control method. In this case, in order to further accurately detect the air conditioner, determine whether the air conditioner needs anti-condensation, so in step S100, three parameter values are introduced: the indoor environment temperature, the outdoor environment temperature and the air outlet temperature of the air conditioner are detected and processed to judge whether the air conditioner meets the condensation preventing condition or not.
In step S200, the operation parameters of the air conditioner are determined, and when the operation parameters meet the condensation preventing conditions, it is indicated that condensation has occurred at the air outlet of the indoor unit at this time, so that the condensation preventing is required, and the air conditioner is controlled to operate, and the anti-condensation mode is entered.
In this embodiment, the commonly used anti-condensation detection parameters include indoor and outdoor environment temperatures or simply detect the temperature of the air outlet of the indoor unit, so that whether condensation exists cannot be comprehensively and accurately judged. In the scheme, three parameters including outdoor environment temperature, indoor environment temperature and air outlet temperature of an indoor unit are introduced, and the three parameters are combined to judge whether the air conditioner generates condensation or not, so that whether the air conditioner generates condensation or not can be judged, and compared with other judging conditions, the judging method provided by the scheme is more accurate. In addition, in the scheme, besides judging whether the condensation is generated, the anti-condensation control method is further included, in the steps, after the judgment is finished, if the condensation exists, the air conditioner is directly controlled to enter an anti-condensation mode, so that the control method is more complete, and the problem of the generation of the condensation can be comprehensively and effectively solved and treated.
Further, judging whether the operation parameters of the air conditioner meet the condensation preventing conditions or not specifically comprises:
step S210: judging whether the indoor environment temperature and/or the outdoor environment temperature meets the first condensation preventing condition;
step S220: if so, judging whether the air outlet temperature of the air conditioner meets the second condensation preventing condition.
In this embodiment, in the step S200, since the reference parameters are relatively large, the condition for judging whether the air conditioner satisfies the condensation prevention is also increased. Specifically, the method is divided into a first anti-condensation condition and a second anti-condensation condition, and when the two anti-condensation conditions are met at the same time, the air conditioner can be judged to have met the anti-condensation conditions and the anti-condensation operation is required. In step S210, it is determined whether the first condensation preventing condition is satisfied mainly according to the indoor environment temperature and the outdoor environment temperature. The condensation of the air conditioner is mainly formed at the air outlet, and is influenced by the temperature at the air outlet, so that the judging condition of the indoor and outdoor temperature seats is rough, and the condensation can be used as a preliminary judging condition. After step S210 is completed, further, in step S220, the air outlet temperature of the air conditioner is used as a second anti-condensation condition, and the air outlet temperature of the air conditioner is an important condition affecting whether condensation is generated or not, so that further judgment is performed as the second anti-condensation condition, the judgment process is gradually advanced from rough to fine, and the accuracy and the rationality of the judgment process are ensured.
In this embodiment, two anti-condensation conditions are set, and the conditions need to be satisfied at the same time, so that the judging process is more detailed and accurate, the accuracy of the judging result is improved, and the judging process is more efficient. In addition, in the two judging conditions, the first judging condition is a rough judging condition, the second anti-condensation condition is a more accurate judging condition, and the judging process is gradually progressed from rough to fine, so that the accuracy and the rationality of the judging process are ensured.
Further, judging whether the indoor environment temperature and/or the outdoor environment temperature meet the first condensation preventing condition or not specifically includes:
step S211: judging whether the air conditioner operates for a first operation duration, and if so, meeting a first condensation preventing condition.
In this embodiment, when the indoor environment temperature and the outdoor environment temperature are determined, specifically, whether the first condensation preventing condition is satisfied is determined by determining whether the air conditioner operates for the first operation duration. Specifically, the judgment of the indoor environment temperature needs to be compared and judged according to the first indoor environment temperature threshold value and the second indoor environment temperature threshold value. The judgment of the outdoor environment temperature needs to be carried out according to the first outdoor environment temperature threshold value and the second outdoor environment temperature threshold value. When the indoor environment temperature and the outdoor environment temperature are simultaneously in the corresponding threshold ranges, the air conditioner is controlled to be started and operated for a first operation duration. Under the temperature condition, when the first operation time length after the air conditioner is started is met, the first condensation prevention condition of the air conditioner can be judged to be met, and the fact that condensation is generated at the moment with high probability is indicated.
Specifically, in the scheme, the first indoor environment temperature threshold is 30 ℃, and the second indoor environment temperature threshold is 15 ℃; the first indoor ambient temperature may be greater than 30 ℃, may be less than 15 ℃, and may be between 15 ℃ and 30 ℃. The first outdoor ambient temperature threshold is 30 ℃ and the second outdoor ambient temperature threshold is 20 ℃; the first outdoor ambient temperature may be greater than 30 ℃, may be less than 20 ℃, and may be between 20 ℃ and 30 ℃. The first operation time period after the air conditioner is started can be 5h, 4h, 5h, 2h and 1h. When the indoor environment temperature is in the certain range and the outdoor environment temperature is in the certain corresponding range, the air conditioner is operated for the first time period, and the air conditioner meets the first anti-condensation condition.
In this embodiment, the indoor and outdoor environment temperatures are not accurately judged, and for more accurate judgment, the air conditioner is controlled to operate for a first operation time, and after the first operation time, it is indicated that the air conditioner maintains the indoor and outdoor environment temperatures in the corresponding states for a period of time, and at this time, the possibility of condensation is higher, so that erroneous judgment caused by larger fluctuation of the temperature is avoided.
Further, the magnitude of the first operating period is proportional to the indoor ambient temperature and/or the outdoor ambient temperature.
In this embodiment, when the first operation duration is determined, the value of the first operation duration set in this case is positively correlated with the indoor environment temperature and the outdoor environment temperature.
When the indoor environment temperature is higher, for example, the indoor environment temperature is higher than 30 ℃, the temperature of the environment where the air conditioner is located is higher, condensation is easy to generate, the first operation time is required to be controlled to be shorter and can be 3-1 h, and long operation time is not required to judge whether the condensation is generated; when the indoor environment temperature is higher, for example, the indoor environment temperature is higher than 15 ℃ and lower than 30 ℃, the temperature of the environment where the air conditioner is located is higher, condensation is easier to generate, the first operation time is required to be controlled to be longer and can be 4-2 hours, and the operation is required to be longer to judge whether the condensation is generated or not; when the indoor environment temperature is low, for example, the indoor environment temperature is lower than 15 ℃, the temperature of the environment where the air conditioner is located is low, condensation is not easy to generate, the first operation time length needs to be controlled to be long and can be 5-3 hours, and a long operation time is needed to judge whether the condensation is generated.
When the outdoor environment temperature is higher, for example, the outdoor environment temperature is higher than 30 ℃, the outdoor environment temperature is high, and condensation is not easy to generate, at the moment, the first operation time is required to be controlled to be longer and can be 3 hours, 4 hours or 5 hours, and the operation is carried out for a long time to judge whether the condensation is generated; when the outdoor environment temperature is higher, for example, the outdoor environment temperature is higher than 20 ℃ and lower than 30 ℃, the outdoor environment temperature is higher, the condensation is not easy to generate, the first operation time is required to be controlled to be longer and can be 2 hours, 3 hours or 4 hours, and the operation is carried out for a long time to judge whether the condensation is generated; when the outdoor environment temperature is lower, for example, the outdoor environment temperature is lower than 20 ℃, the outdoor environment temperature is low, condensation is easy to generate, the first operation time is required to be controlled to be shorter, and can be 1h, 2h or 3h, and the first operation time is required to be operated for a shorter time to judge whether the condensation is generated.
In this embodiment, the operation duration is selected according to the temperature range, so that time can be saved more efficiently to determine whether the air conditioner generates condensation, and the determination time is reasonably planned, so that the determination is accurate and more efficient and time-saving.
Further, judging whether the air outlet temperature of the air conditioner meets the second condensation preventing condition or not, specifically comprising:
Step S221: detecting the air outlet temperature of the air conditioner every first time period, and if the air outlet temperature meets the air outlet temperature threshold value, meeting the second condensation preventing condition.
In this embodiment, in step S221, in order to determine whether the second condensation preventing condition is satisfied, the air outlet temperature and the air outlet temperature threshold are compared. Because the air outlet temperature is the air outlet temperature under the running state of the air conditioner, the air outlet temperature can be changed along with different running modes of the air conditioner, and the air outlet temperature of the air conditioner is not very stable. Therefore, in the judging step, when the air outlet temperature is detected, the air outlet temperature is detected once every first time period, and the air outlet temperature is compared with an air outlet temperature threshold value.
In this embodiment, the first time interval is set to detect the air outlet temperature, so that inaccurate judgment results can be avoided when the air outlet temperature is changed, the air outlet temperature can be detected at a higher frequency, and the judgment results can be corrected in time according to the change of the air outlet temperature.
Further, the first time period is proportional to the outdoor ambient temperature.
In this embodiment, the air outlet temperature of the air conditioner is detected every first time period, and the first time period is also adjusted according to the difference of the outdoor environment temperature.
Specifically, the size of the first period of time is positively correlated with the outdoor ambient temperature. When the outdoor environment temperature is high, the first time period is long, and detection can be performed at intervals, for example, the first time period can be 30min, 40min or 50min; when the outdoor environment temperature is smaller, the first time period is shorter, and detection can be performed at a shorter interval, for example, the first time period can be 20min, 30min or 40min; when the outdoor environment temperature is smaller, the first time period is also shorter, and detection can be performed at a shorter interval, for example, the first time period can be 10min, 20min or 30min.
In this embodiment, the frequency of detecting the air-out temperature is adjusted according to outdoor ambient temperature, makes the detection frequency more reasonable, can satisfy the detection demand more, saves the detection number of times.
Further, step S230: the method for controlling the air conditioner to enter the condensation preventing mode specifically comprises the following steps: and the air output of the indoor unit of the air conditioner is improved.
In this embodiment, the specific condensation preventing control method mainly aims at controlling the air output of the air conditioner. When the air output is large, the air output of the air conditioner is large, and condensation is not easy to generate. In the scheme, various modes of adjusting the air output are adopted, the running frequency of the compressor is adjusted, the air deflector of the air conditioner is controlled to rotate to the maximum air outlet, the rotating speed of the fan is controlled, and the like, so that the air output of the indoor unit of the air conditioner can be improved.
In this embodiment, the air outlet of the indoor fan of the air conditioner is improved, so that the anti-condensation of the air conditioner can be controlled in a targeted manner, one of the main reasons for the condensation of the air conditioner is that the air outlet of the indoor unit is not large enough, the control method in the scheme is used for controlling and improving the main problems, the pertinence is strong, and the problem solving efficiency is higher.
Further, the air outlet of the indoor unit of the air conditioner is improved, and the air conditioner specifically comprises:
step S231: controlling the angle of an air deflector of the air conditioner to be the optimal angle;
and/or
Step S232: and (5) increasing the rotating speed of the indoor unit fan according to the amplitude f, wherein f is r/min.
In this embodiment, two control conditions with relatively high correlation with the air output of the indoor fan are the air guide plate angle and the indoor fan rotating speed, and the two conditions directly affect the air output of the indoor unit, so that the air output of the indoor unit is improved by selecting the two control schemes, the control effect is better, and the condensation prevention effect is better.
Further, the magnitude of the amplitude f is inversely proportional to the outdoor ambient temperature.
In this embodiment, when the air output is increased, the air deflector angle is controlled to be the maximum, but the rotation speed of the indoor fan needs to be further selected according to the indoor and outdoor environment temperatures. The rotating speed of the indoor fan is inversely related to the indoor and outdoor environment temperature, and when the outdoor environment temperature is high, the rotating speed is higher than 30 ℃ and the rotating speed is 50r/min; when the outdoor environment temperature is higher, the temperature is higher than 20 ℃ and lower than 30 ℃, and the lifting amplitude is 100r/min; when the outdoor environment temperature is lower, the temperature is lower than 20 ℃, and the lifting amplitude is 150r/min.
In this embodiment, the lifting amplitude of the rotation speed of the indoor fan is adjusted according to the outdoor environment temperature, so that the fan rotation speed is prevented from being too high and exceeds a reasonable range.
