Referring to fig. 1, an embodiment of the present disclosure provides a method for controlling condensation prevention of an air conditioner, including:
s01, the processor of the air conditioner determines coil temperature Tp and dew point temperature T, calculates delta T as Tp-T, and determines the value of delta T;
s02, the processor of the air conditioner determines the rotating speed r of the inner fan, calculates K as delta T/r, and determines the value of K;
and S03, controlling the rotating speed of the inner fan, the rotating speed of the outer fan and the frequency of the compressor by the processor of the air conditioner according to the interval where the value of K is located.
By adopting the method for controlling the air conditioner to prevent condensation provided by the embodiment of the disclosure, the coil temperature and the dew point temperature are obtained, and the rotating speed of the inner fan is obtained at the same time, whether condensation is easy to generate can be judged according to the temperature difference between the coil temperature and the dew point temperature under the general condition, but the rotating speed of the inner fan has certain influence on whether condensation is generated, the rotating speed of the inner fan is increased, the air speed flowing through the coil is increased, the heat exchange efficiency of the coil can be improved, the cold quantity of the coil is better taken away, the temperature of the coil is favorably increased, the possibility of condensation is further reduced, meanwhile, the air flow can faster pass through the coil due to the increase of the air speed, the heat quantity of the air flow in unit volume contacting and exchanging with the coil is reduced, the generation of condensation can also be reduced, therefore, 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 to judge whether condensation is easy to generate, more accurate to this rotational speed and the compressor frequency of fan in controlling, outer fan can prevent that the condensation from producing under the minimum condition of air conditioning cooling capacity influence, and then prevents that the air conditioner from blowing water, satisfies the demand of user to air conditioner refrigeration ability and to prevent blowing the demand of water function.
It is understood that the coil temperature is detected by a temperature sensor disposed near the coil, the dew point temperature is calculated from the detected indoor temperature and the indoor humidity, and the rotation speed of the inner fan is obtained by a controller for controlling the rotation speed of the fan.
Alternatively, as shown in fig. 2, executing S01, determining coil temperature Tp and dew point temperature T, and calculating Δ T as Tp-T, wherein determining the value of Δ T further includes:
and S04, the processor of the air conditioner judges the time length of the air conditioner during the starting operation, and executes S01 under the condition that the time length of the air conditioner during the starting operation exceeds the preset time length. Like this, can not produce the condensation phenomenon under the general condition in air conditioner start operation earlier stage, need not prevent the condensation control this moment, prevent to influence the normal operating of air conditioner, when the air conditioner operation after a period tend to stable under the condition execute S01 again and prevent that the air conditioner from producing the condensation, reduce and prevent the influence that the condensation control process produced such as air conditioner normal temperature regulation.
Optionally, the preset time period is greater than or equal to 5 minutes and less than or equal to 10 minutes. Thus, the operation state of the air conditioner tends to be stable in the starting operation for 5 to 10 minutes in general, and the condensation phenomenon is easy to generate under the condition that the humidity in the air is too high, so that after the starting operation for 5 to 10 minutes, S01 is executed to perform condensation prevention control on the air conditioner, the generation of condensation can be effectively prevented, the operation of adjusting the temperature and the like of the air conditioner is not influenced, and the stability of the operation of the air conditioner is improved.
Optionally, as shown in fig. 3, executing S01, determining coil temperature Tp and dew point temperature T, and calculating Δ T as Tp-T, wherein determining the value of Δ T further includes:
and S05, the processor of the air conditioner acquires the anti-condensation instruction, and executes S01 under the condition that the anti-condensation instruction is determined to be acquired. Like this, can open through preventing condensation control command and prevent the condensation function under the condition that the user is artificial to judge whether need prevent that the air conditioner from blowing water, use more in a flexible way, avoid influencing the operation of other functions of air conditioner, prevent that the condensation function need not open when for example needing the dehumidification.
It is understood that the anti-condensation command is issued by the remote controller of the air conditioner or obtained by obtaining a user voice command. Control more reliable and more stable through the air conditioner remote controller, and control then more intelligent convenient through acquireing user's voice command.
Optionally, according to the interval where the value of K is located, controlling the rotation speed of the inner fan, the rotation speed of the outer fan, and the compressor frequency 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, increasing the rotating speed of the inner fan to the maximum value of the rotating speed of the inner fan, and reducing the rotating speed of the outer fan and the frequency of the compressor until K is more than a. Thus, when the temperature of the coil is higher than the dew point temperature, DeltaT is a positive number, and K is a positive number at the time, when the temperature of the coil pipe is closer to the dew point temperature, the value of delta T is smaller, the value of K is smaller, and K is less than or equal to a, the temperature of the coil pipe is close to the dew point temperature, the risk of generating condensation exists at any time, 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, simultaneously, the rotating speed of the outer fan and the frequency of the compressor are reduced, the temperature of the coil pipe is increased, the value of delta T is improved, further increases K, when K is larger than a, the difference between the temperature of the coil pipe and the dew point temperature is increased, the risk of condensation is lower, the phenomenon of water blowing can be avoided, meanwhile, the heat exchange is accelerated by increasing the rotating speed of the inner fan, and further the refrigerating capacity of the air conditioner can be kept, namely the condensation prevention and the refrigerating capacity of the air conditioner can be taken into consideration.
Optionally, increasing the rotation speed of the inner fan to the maximum value of the rotation speed of the inner fan includes: the rotating speed of the inner fan is directly adjusted 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 rotating speed is required to be increased to the maximum value, and the fan rotating speed can be regulated and controlled directly and conveniently in one step. But fan rotational speed adjustment is too fast, leads to the operation to be stable inadequately easily, can directly blow off few condensation under the condition that has the condensation on the coil pipe, causes the air conditioner and blows water phenomenon, increases the rotational speed that makes interior fan according to first settlement and progressively improves, 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 off.
Alternatively, 0.00901 ≦ a ≦ 0.00905. Therefore, the difference value between the coil temperature and the dew point temperature is at the critical point of being about to condense under the condition that the value of a is set between 0.00901 and 0.00905, so that whether the risk of condensing of the air conditioner is more reliable or not is judged, the judgment precision can be improved, an inner fan, an outer fan and a compressor of the air conditioner are better controlled, and the condensing is prevented while the refrigerating capacity of the air conditioner is kept. Preferably, a is 0.00903.
Optionally, according to the interval where the value of K is located, controlling the rotation speed of the inner fan, the rotation speed of the outer fan, and the compressor frequency includes:
and 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 under the condition that the temperature of the coil is less than or equal to the dew point temperature and c is less than or equal to K and less than b. Therefore, under the condition that the temperature of the coil pipe is less than or equal to the dew point temperature, if the rotating speed of the inner fan is not considered at this moment, the condensation risk exists, but the rotating speed of the inner fan has certain influence on the condensation, so the ratio K of the temperature difference delta T between the temperature of the coil pipe and the dew point temperature to the rotating speed r of the inner fan is in a specific interval, the balance can be maintained, even if the temperature of the coil pipe 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 the unit air flow and the coil pipe is short, enough heat cannot be released to condense the water vapor, the condensation cannot be generated at this moment, or the condensation amount is small, the water blowing phenomenon cannot be formed, and the rotating speed of the inner fan, the rotating speed of the outer fan and the frequency of the compressor are controlled to maintain the current operation condition, so that the condensation can be avoided.
It is understood that controlling the rotation speed of the inner fan, the rotation speed of the outer fan and the frequency of the compressor to maintain the current state means keeping the rotation speed of the inner fan, the rotation speed of the outer fan and the frequency of the compressor unchanged without acquiring the conditions that the user actively adjusts the wind speed and adjusts the temperature.
Optionally, according to the interval where the value of K is located, controlling the rotation speed of the inner fan, the rotation speed of the outer fan, and the compressor frequency includes:
and under the condition that the temperature of the coil is less than or equal to the dew point temperature and d is less than or equal to K and less than c, controlling the rotating speed of the outer fan and the frequency of the compressor to be unchanged, and increasing the rotating speed of the inner fan until c is less than or equal to K and less than b. Thus, the temperature of the coil is less than or equal to the dew point temperature, the condensation risk is realized under the condition that the rotating speed of the inner fan is not considered, the value of delta T is negative, the lower the temperature of the coil is, the smaller the value of K is, when the value of K is less than c, the condensation is easy to occur on the coil, but the condensation amount is not large under the condition that the value of K is between c and d, 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 value of K can be increased to enable the value of K to fall between c and b again, the balance is kept, the condensation is prevented, the contact time of water vapor in unit airflow and the coil can be reduced by increasing the rotating speed of the inner fan, the water vapor in the airflow is not enough to release enough heat to generate the condensation, the water blowing phenomenon is prevented, meanwhile, the rotating speed of the inner fan is increased, the heat exchange efficiency is increased, and the refrigerating capacity of the air conditioner is not influenced, the indoor temperature is kept stable, and the user experience is improved.
Optionally, increasing the rotating speed of the inner fan by a second set amplification until c is less than or equal to K and less than b. Therefore, the rotating speed of the inner fan is gradually increased by the second setting, the rotating speed changes uniformly, and the adjustment of the rotating speed of the inner fan is stopped in time when the value of K meets the condition that c is not less than K and is less than b.
Optionally, the second set amplification is less than the first set amplification. Therefore, in the process of adjusting the rotating speed of the inner fan to enable the value of K to meet the condition that c is not more than K and is less than b, the adjustment of the rotating speed of the inner fan can be stopped at any time, so that the rotating speed of the inner fan can be controlled more accurately by setting the second set amplification to be too small, and the rotating speed of the inner fan can be adjusted more reasonably.
Optionally, the first set amplification is greater than or equal to 10 revolutions per second and less than or equal to 15 revolutions per second. Therefore, the first set amplification is set to be 10 revolutions per second to 15 revolutions per second, so that the rotating speed of the inner fan can be quickly increased, the reaction time for increasing the rotating speed of the fan is shortened, and a small amount of condensation is not blown out due to quick adjustment. Preferably, the first set amplification is 10 revolutions per second.
Optionally, the second set increase is greater than or equal to 3 revolutions per second and less than or equal to 7 revolutions per second. Therefore, the second set amplification is set in the interval of 3 revolutions per second to 7 revolutions per second, the rotating speed of the inner fan can be stably improved, the rotating speed lifting amplitude is moderate, the adjustment of the rotating speed of the inner fan is timely stopped when the value of K reaches the condition that c is not more than K and is less than b, and the rotating speed of the inner fan is kept in a reasonable range. Preferably, the second set amplification is 5 revolutions per second.
Alternatively, -0.000883. ltoreq. b.ltoreq. 0.00088, -0.00534. ltoreq. c.ltoreq. 0.005342, -0.00682. ltoreq. d.ltoreq. 0.006824. 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 high, water vapor in the airflow rapidly passes through the coil at the moment and is not enough to release heat condensation, and the risk of generating condensation is low at the moment; when the value of K is between-0.005342 and-0.00682, the temperature of the coil pipe is lower than the dew point temperature, so that the risk of condensation is high, the rotating speed of the inner fan is controlled to be increased, the value of K can be increased, the K falls between-0.00088 and-0.005342 again, the rotating speed of the inner fan is increased, water vapor in airflow rapidly passes through the coil pipe, heat cannot be released, condensation is generated, and the risk of condensation is low; when the value of K is smaller than the interval from-0.00682 to-0.006824, the phenomenon that condensation is generated due to the fact that the temperature of the coil is too low is shown, and 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 firstly, the temperature of the coil is quickly increased, the generation of condensation is reduced, when the value of K is changed to fall between-0.00088 and-0.005342 after the temperature of the coil is increased, the risk of condensation is reduced, the generation of condensation can be effectively prevented, and due to the fact that the rotating speed of the inner fan is increased, heat exchange efficiency is increased, and the influence on the refrigerating capacity of the air conditioner is small. Preferably, b is 0.000881, c is 0.006822, and d is 0.005341.
Optionally, according to the interval where the value of K is located, controlling the rotation speed of the inner fan, the rotation speed of the outer fan, and the compressor frequency includes:
and under the condition that the temperature of the coil is less than or equal to the dew point temperature and K is less than d, controlling the frequency of the compressor to reduce by a first reduction amplitude, and controlling the rotating speed of the outer fan to reduce by a second reduction amplitude until d is less than or equal to K and less than c. Like this, coil pipe temperature is crossed lowly under the condition that K is less than d, need promote coil pipe temperature, can promote coil pipe temperature this moment through the rotational speed that reduces outer fan and the frequency that reduces the compressor, wherein the frequency of compressor evenly reduces with first descending amplitude, the rotational speed of outer fan evenly reduces with the second descending amplitude, the frequency that can prevent the compressor and the rotational speed change of outer fan lead to the undulant great refrigeration capacity who influences the air conditioner of coil pipe temperature at the excessive speed, prevent the condensation at the air conditioner, avoid the in-process that blows, it has sufficient refrigeration capacity to keep the air conditioner.
Optionally, the frequency of the compressor is controlled to be reduced by a first amplitude reduction, the rotating speed of the outer fan is controlled to be reduced by a second amplitude reduction, and the rotating speed of the inner fan is continuously controlled to be increased under the condition that d is less than or equal to K and less than c. Therefore, after the temperature of the coil pipe is increased by controlling the frequency of the compressor and the rotating speed of the outer fan, the risk of condensation still exists 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 at the moment until c is less than or equal to K and less than b, and the condensation can be better prevented.
Optionally, the first step-down is 0.1 hertz per second.
