By adopting the method for controlling the air conditioner anti-condensation provided by the embodiment of the disclosure, the coil temperature and the dew point temperature are obtained, and meanwhile, the rotating speed of the inner fan is obtained, so that whether the condensation is easy to occur can be judged according to the temperature difference between the coil temperature and the dew point temperature in general cases, but the rotating speed of the inner fan has a certain influence on whether the condensation occurs, the rotating speed of the inner fan is improved, the air speed flowing through the coil is improved, the heat exchange efficiency of the coil can be improved, the cooling capacity of the coil is better taken away, the improvement of the coil temperature is facilitated, the possibility of condensation is further reduced, meanwhile, the air speed is improved, the air flow is enabled to pass through the coil more quickly, the heat which is in contact with and exchange with the coil in unit volume is reduced, and the generation of the condensation can be reduced, so that the temperature difference delta T between the coil temperature and the dew point temperature is combined with the rotating speed r of the inner fan is judged whether the condensation is easy to occur or not, the condensation is more accurate, the rotating speed of the inner fan, the rotating speed of the outer fan and the frequency of the compressor are controlled, the condensation is prevented under the condition that the influence on the cooling capacity of the air conditioner is minimum, and the air conditioner is further prevented from generating the air conditioner, and the air conditioner is satisfied, and the requirements on the air conditioning capacity and the water is also required by the air conditioner.
It will be appreciated that the coil temperature is sensed by a temperature sensor disposed adjacent the coil, the dew point temperature is calculated from the sensed indoor temperature and indoor humidity, and the rotational speed of the inner blower is obtained by a controller that controls the rotational speed of the blower.
Optionally, as shown in fig. 2, performing S01, determining the coil temperature Tp and the dew point temperature T, and calculating Δt=tp-T, and before determining the value of Δt, further includes:
s04, the processor of the air conditioner judges the starting operation time of the air conditioner, and S01 is executed under the condition that the starting operation time of the air conditioner exceeds the preset time. Therefore, condensation phenomenon can not be generated in the prior period of the startup operation of the air conditioner under the general condition, at the moment, anti-condensation control is not needed, the normal operation of the air conditioner is prevented from being influenced, the S01 is executed again under the condition that the operation of the air conditioner is stable after a period of time, the air conditioner is prevented from generating condensation, and the influence of the anti-condensation control process on the normal temperature regulation of the air conditioner is reduced.
Optionally, the preset time period is greater than or equal to 5 minutes and less than or equal to 10 minutes. Therefore, the air conditioner is generally stable in running state when the air conditioner is started and runs for 5 to 10 minutes, and the condensation phenomenon is easy to generate under the condition of overhigh humidity in the air, so that after the air conditioner is started and runs for 5 to 10 minutes, S01 is executed to control the condensation prevention of the air conditioner, the generation of the condensation can be effectively prevented, the operation such as temperature regulation of the air conditioner is not influenced, and the running stability of the air conditioner is improved.

s05, the processor of the air conditioner acquires the anti-condensation instruction, and S01 is executed under the condition that the anti-condensation instruction is acquired. Therefore, the anti-condensation function can be started through the anti-condensation control instruction under the condition that a user manually judges whether the air conditioner is required to blow water or not, the use is more flexible, the operation affecting other functions of the air conditioner is avoided, and for example, the anti-condensation function is not required to be started when dehumidification is required.
It will be appreciated that the anti-condensation instruction is issued by the air conditioner remote control or obtained by obtaining a user voice instruction. The control is more stable and reliable through the air conditioner remote controller, and the control is more intelligent and convenient through acquiring the voice command of the user.
Optionally, controlling the rotation speed of the inner fan, the rotation speed of the outer fan and the compressor frequency according to the interval where the value of K is located includes:
and under the condition that the temperature of the coil pipe is higher than the dew point temperature and K is less than or equal to a, the rotating speed of the inner fan is increased to the highest value of the rotating speed of the inner fan, and the rotating speed of the outer fan and the frequency of the compressor are reduced until K is more than a. Thus, when the temperature of the coil is larger than the dew point temperature, deltaT is a positive number, K is also a positive number, when the temperature of the coil is closer to the dew point temperature, the smaller the value of DeltaT is, and the smaller the value of K is, K is smaller than or equal to a, the coil temperature is relatively close to the dew point temperature, the risk of condensation is generated at any time, at the moment, the rotating speed of the inner fan is increased to the highest rotating speed of the inner fan, the gas circulation can be accelerated, the heat exchange efficiency is improved, the rotating speed of the outer fan and the frequency of the compressor are reduced, the temperature of the coil is increased, the DeltaT is increased, the K is further increased, when K is larger than a, the difference between the temperature of the coil and the dew point temperature is increased, the risk of condensation is lower, the phenomenon of blowing water can be avoided, the rotating speed of the inner fan is increased, the heat exchange can be accelerated, the refrigerating capacity of the air conditioner can be maintained, and the refrigerating capacity of the air conditioner can be prevented from condensation and also can be considered.
Optionally, increasing the rotational speed of the inner blower to a maximum value of the rotational speed of the inner blower includes: the rotating speed of the inner fan is directly regulated to the highest value, or the rotating speed of the inner fan is gradually increased to the highest value of the rotating speed of the inner fan according to the first set amplification. Therefore, the fan speed is required to be increased to the highest value, and the one-step regulation and control are more convenient and faster. But the fan rotational speed adjustment is too fast, leads to running unstable easily, can directly blow out a small part of condensation under the condition that there is condensation on the coil pipe, causes the air conditioner to blow out the water phenomenon, makes the rotational speed of inner fan gradually improve according to first settlement increase in amplitude, and the process is softer, can improve the stability of air conditioner operation to prevent that a small amount of condensation on the coil pipe from being blown out.
Alternatively, 0.00901.ltoreq.a.ltoreq. 0.00905. Therefore, the difference between the temperature of the coil and the dew point temperature is at the critical point to be condensed under the condition that the value of a is between 0.00901 and 0.00905, so that whether the air conditioner is at risk of condensation or not is judged more reliably, the judgment precision can be improved, the inner fan, the outer fan and the compressor of the air conditioner are better controlled, and the condensation is prevented while the refrigerating capacity of the air conditioner is maintained. Preferably, a= 0.00903.
Optionally, controlling the rotation speed of the inner fan, the rotation speed of the outer fan and the compressor frequency according to the interval where the value of K is located includes:
and under the condition that the temperature of the coil pipe is less than or equal to the dew point temperature and c is less than or equal to K and less than b, controlling the rotating speed of the inner fan, the rotating speed of the outer fan and the frequency of the compressor to maintain the current state. Therefore, under the condition that the temperature of the coil is less than or equal to the dew point temperature, if the rotating speed of the inner fan is not considered, the risk of condensation exists, but because the rotating speed of the inner fan has a certain influence on the condensation, the balance can be maintained when the ratio K of the temperature difference delta T between the temperature of the coil and the dew point temperature to the rotating speed r of the inner fan is within a specific interval, even if the temperature of the coil is lower than the dew point temperature, the flowing speed of the air flow is too high, the contact time of the water vapor in unit air flow and the coil is short, enough heat is not released to cause the condensation of the water vapor, the condensation can not be generated at the moment, or the quantity of the condensation is small, the phenomenon of blowing water can not be formed, and therefore, the generation of the condensation can be avoided by controlling the rotating speed of the inner fan, the rotating speed of the outer fan and the frequency of the compressor to maintain the current running condition.
It will be understood that controlling the rotational speed of the inner fan, the rotational speed of the outer fan, and the frequency of the compressor to maintain the current state means that the rotational speed of the inner fan, the rotational speed of the outer fan, and the frequency of the compressor are maintained without acquiring the user's active adjustment of the wind speed and the adjustment of the temperature.
Optionally, controlling the rotation speed of the inner fan, the rotation speed of the outer fan and the compressor frequency according to the interval where the value of K is located includes:
and under the condition that the temperature of the coil pipe is less than or equal to the dew point temperature and d is less than or equal to K and less than or equal to C, controlling the rotating speed of the outer fan and the frequency of the compressor to be unchanged, and improving the rotating speed of the inner fan until c is less than or equal to K and less than b. Therefore, the temperature of the coil is smaller than or equal to the dew point temperature, the risk of condensation exists under the condition that the rotating speed of the inner fan is not considered, at the moment, the DeltaT value is a negative number, the lower the temperature of the coil is, the smaller the K value is, the coil is easy to condense, but the condensation quantity is not large under the condition that the K value is smaller than the C value, at the moment, the rotating speed of the outer fan and the frequency of the compressor are kept unchanged, the rotating speed of the inner fan is increased, the K value can be increased to fall between the C and the b again, balance is kept, the condensation is prevented, the contact time of water vapor in unit airflow and the coil is reduced by increasing the rotating speed of the inner fan, the sufficient heat is not released enough to generate condensation, the phenomenon of blowing water is prevented, meanwhile, the rotating speed of the inner fan is increased, the refrigerating capacity of an air conditioner is not influenced, the indoor temperature is kept stable, and the experience of a user is improved.
Optionally, increasing the rotation speed of the inner fan by a second set increase until c is less than or equal to K < b. Thus, the rotating speed of the inner fan is gradually increased by the second setting, the rotating speed change is uniform, and the adjustment of the rotating speed of the inner fan is stopped in time under the condition that the value of K is more than or equal to c and less than or equal to K and less than b.
Optionally, the second set amplification is less than the first set amplification. In this way, in the process of adjusting the rotating speed of the inner fan to ensure that the value of K meets the value of c is less than or equal to K and less than b, the adjustment of the rotating speed of the inner fan can be stopped at any time, so that the second setting amplification setting is too small, the rotating speed of the inner fan can be controlled more accurately, and the rotating speed adjustment of the inner fan is more reasonable.
Optionally, the first set increase is greater than or equal to 10 revolutions per second and less than or equal to 15 revolutions per second. In this way, setting the first set amplification at 10-15 revolutions per second can enable the rotating speed of the inner fan to be quickly increased, reduce the reaction time of the rotating speed increase of the fan, and prevent a small amount of condensate from being blown out due to too quick adjustment. Preferably, the first set amplification is 10 revolutions per second.
Optionally, the second set amplification is greater than or equal to 3 revolutions per second and less than or equal to 7 revolutions per second. Therefore, the second setting amplification is set in the interval from 3 to 7 revolutions per second, the rotating speed of the inner fan can be stably increased, the rotating speed increasing amplitude is moderate, and the adjustment of the rotating speed of the inner fan can be timely stopped under the condition that the value of K is more than or equal to c and less than or equal to K and less than b, so that the rotating speed of the inner fan is kept in a reasonable range. Preferably, the second set-up amplification is 5 revolutions per second.

Thus, under the condition that the value of K is between-0.00088 and-0.005342, although the temperature of the coil is lower than the dew point temperature, the rotating speed of the inner fan is higher, and the water vapor in the air flow rapidly passes through the coil and is insufficient for releasing the heat condensation, so that the risk of generating the condensation is lower; when the value of K is between-0.005342 and-0.00682, the temperature of the coil is lower than the dew point temperature, so that more condensation is caused, the rotating speed of the inner fan is controlled to be increased, the value of K can be increased to fall between-0.00088 and-0.005342 again, the rotating speed of the inner fan is increased, and water vapor in air flow rapidly passes through the coil and is insufficient for releasing heat condensation, so that the risk of condensation is small; when the value of K is smaller than the interval from-0.00682 to-0.006824, the temperature of the coil pipe is too low, condensation can be generated, the effect of simply adjusting the rotating speed of the inner fan is not obvious enough, so that the rotating speed of the outer fan and the frequency of the compressor are reduced, the temperature of the coil pipe is quickly increased, the generation of the condensation is reduced, when the value of K changes to fall between-0.00088 and-0.005342 after the temperature of the coil pipe is increased, the risk of the condensation is reduced, the generation of the condensation can be effectively prevented, and the influence on air conditioning cooling capacity is small due to the increase of the rotating speed of the inner fan, the heat exchange efficiency is increased. Preferably, b=0.000881, c=0.006822, d= 0.005341.
Optionally, controlling the rotation speed of the inner fan, the rotation speed of the outer fan and the compressor frequency according to the interval where the value of K is located includes:
and under the condition that the temperature of the coil pipe is less than or equal to the dew point temperature and K < d, controlling the frequency of the compressor to be reduced by a first reduction, and controlling the rotating speed of the external fan to be reduced by a second reduction until d is less than or equal to K < c. Like this, coil pipe temperature is too low under the condition that K is less than d, need promote coil pipe temperature, can promote coil pipe temperature through the rotational speed that reduces the outer fan and reduce the frequency of compressor this moment, wherein the frequency of compressor evenly reduces with first decline, the rotational speed of outer fan evenly reduces with the second decline, can prevent the frequency of compressor and the rotational speed of outer fan change excessively fast and lead to the great refrigerating capacity that influences the air conditioner of coil pipe temperature fluctuation, prevent the condensation at the air conditioner, avoid blowing the in-process of water, keep the air conditioner to have sufficient refrigerating capacity.
Optionally, controlling the frequency of the compressor to be reduced by a first amplitude reduction, controlling the rotating speed of the outer fan to be reduced by a second amplitude reduction, and continuously controlling the rotating speed of the inner fan to be increased by d.ltoreq.K < c after d.ltoreq.K < c is satisfied. Therefore, after the temperature of the coil is increased by controlling the frequency of the compressor and the rotating speed of the outer fan, the risk of condensation is still caused under the condition that d is less than or equal to K and less than c, and therefore, the rotating speed of the inner fan still needs to be adjusted until c is less than or equal to K and less than b, and the generation of condensation can be better prevented.
Optionally, the first amplitude reduction is 0.1 hertz per second. Therefore, the frequency of the compressor is reduced by 0.1 Hz per second, the frequency of the compressor is uniformly reduced, the running stability of the compressor is improved, and the adjustment of the frequency of the compressor is stopped in time after the value of K accords with d < K < c, so that the frequency of the compressor is controlled in a reasonable range.
Optionally, the second reduction is 10 revolutions per second. Therefore, the rotating speed of the outdoor fan is reduced at the speed of 10 revolutions per second, and the adjustment of the rotating speed of the outdoor fan is stopped in time after the value of K accords with d which is less than or equal to K which is less than c, so that the rotating speed of the outdoor fan is controlled within a reasonable range.
Optionally, the value of K is recalculated every set time period while controlling the rotation speed of the inner fan, the rotation speed of the outer fan, and the frequency of the compressor. Therefore, the value of K can be recalculated every set time, the interval where the value of K is located can be determined in real time, the rotating speed of the inner fan, the rotating speed of the outer fan and the frequency of the compressor are better controlled, condensation can not be generated in the running process of the air conditioner, the influence on the refrigerating capacity of the air conditioner is minimized, and the user experience is improved.
Alternatively, the set time period is greater than or equal to 10 seconds and less than or equal to 20 seconds. Therefore, the value of K is recalculated within 10 to 20 seconds, the interval where the value of K is located can be better judged, the adjustment of the rotating speed of the inner fan, the rotating speed of the outer fan and the frequency of the compressor is timely stopped, the accuracy of the control of the rotating speed of the inner fan, the rotating speed of the outer fan and the frequency of the compressor is improved, and the phenomenon that condensation causes air conditioner water blowing is avoided, and the influence on the refrigerating capacity of the air conditioner can be avoided.
