Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Referring to fig. 1, fig. 1 shows a flowchart of an anti-condensation control method of an air conditioner of the present application, wherein the air conditioner includes a compressor, an indoor heat exchanger and an indoor fan, the indoor heat exchanger is connected with the compressor, and the compressor can drive a refrigerant to flow to the indoor heat exchanger; the indoor heat exchanger and the indoor fan are arranged in the air supply duct, an air supply opening is formed at the outlet of the air supply duct, the indoor fan can blow air around the indoor heat exchanger to form cold air or hot air, and the cold air or the hot air is blown into a room from the air supply opening. The anti-condensation control method can prevent the air supply outlet from generating condensation, so that the anti-condensation performance of the air conditioner is improved, and the aim of improving user experience is fulfilled.
As shown in fig. 1, the anti-condensation control method of the air conditioner of the present application includes the following steps:
step S1: and acquiring the air outlet humidity of an air supply outlet of the air conditioner.
In this embodiment, a humidity sensor may be disposed at the air supply port, and the signal output end of the humidity sensor is connected to the air conditioner, so that the air-out degree of the air supply port can be detected by the humidity sensor
Step S2: it is determined whether the compressor is operated in a cooling mode or a dehumidifying mode.
The compressor operates in a cooling mode or a dehumidifying mode, which means that the air conditioner operates in the cooling mode or the dehumidifying mode. The user can select a required working mode on a control panel or a remote controller of the air conditioner, and the control panel or the remote controller sends a corresponding control signal to the air conditioner according to a selection result of the user; the air conditioner recognizes the control signal after receiving the control signal, and judges whether to control the air conditioner to operate in a refrigeration mode or a dehumidification mode according to the recognition result.
Or the air conditioner can detect the temperature and the humidity of the indoor environment, when detecting that the temperature of the indoor environment is greater than the expected temperature, the air conditioner is controlled to operate in a refrigeration mode, and when detecting that the humidity of the indoor environment is greater than the expected humidity, the air conditioner is controlled to operate in a dehumidification mode.
Step S3: if the compressor runs in the refrigeration mode or the dehumidification mode, judging whether the air supply speed of the indoor fan is higher than a preset air speed or not and whether the air outlet rheumatism degree of the air supply opening is lower than a first set humidity or not.
Because the temperature of the indoor heat exchanger is low and the indoor environment temperature is high when the air conditioner is in the cooling mode or the dehumidifying mode, moisture in the indoor environment is easy to condense at the air supply port to form condensation. Therefore, in this embodiment, the air conditioner is in the cooling mode or the dehumidifying mode as one of preconditions for condensation prevention of the air conditioner.
When the indoor fan works, the indoor fan can be in a control mode of step adjustment, and the gear comprises a low wind speed mode, a medium wind speed mode and a high wind speed mode, wherein the wind speed of the air supply in the low wind speed mode is smaller than that in the medium wind speed mode, and the wind speed of the air supply in the medium wind speed mode is smaller than that in the high wind speed mode. In this embodiment, the air supply speed of the indoor fan of the air conditioner may be obtained according to the gear of the indoor fan.
In other embodiments, if the speed regulation mode of the indoor fan is the stepless speed regulation mode, the obtained rotational speed of the indoor fan may be directly detected by using a detection device such as an encoder to obtain the rotational speed of the indoor fan, or may be the current of the indoor fan, and the rotational speed of the indoor fan is obtained according to the corresponding relationship between the current and the rotational speed of the indoor fan; and then obtaining the air supply speed of the indoor fan according to the corresponding relation between the rotating speed of the indoor fan and the air supply speed.
Step S4: if the air supply speed of the inner fan is not higher than the preset air speed and the air outlet humidity of the air supply outlet is not lower than the first set humidity, performing anti-condensation treatment on the air supply outlet according to the air outlet humidity of the air supply outlet.
In the refrigerating process of the air conditioner, the smaller the air supply speed of the indoor fan is, the smaller the wind force in the air supply duct is, the less cold air generated around the indoor heat exchanger is discharged from the air outlet, a large amount of cold air is accumulated at the air outlet, the temperature at the air outlet is reduced, and the greater the risk of condensation is generated at the air outlet. And the greater the air outlet humidity of the air outlet of the air conditioner is, the more likely the air outlet is to generate condensation. Therefore, in this embodiment, the air supply speed of the indoor fan and the air outlet air-out degree are used as the condensation preventing judging conditions, so that the reliability of the condensation preventing treatment of the air conditioner can be improved.
When the condensation prevention treatment is performed on the air supply opening, the method comprises the steps of increasing the air supply speed of the indoor fan and/or reducing the operation frequency of the compressor. After the air supply speed of the indoor fan is increased, the wind power in the air supply duct can be increased to blow off the water in the air supply opening so as to prevent the air supply opening from generating condensation; after the operation frequency of the compressor is reduced, the cooling speed of the refrigerant at the indoor heat exchanger can be reduced, so that the temperature of the indoor heat exchanger is reduced, and the moisture in the indoor environment is prevented from condensing at the air supply outlet, thereby realizing the condensation prevention treatment on the air supply outlet of the indoor unit.
According to the technical scheme, whether the air supply outlet of the indoor unit is at risk of generating condensation is judged according to the working state of the air conditioner, the air supply speed of the indoor fan and the air outlet wind-damp degree of the air supply outlet, and when the risk of generating condensation exists, the air supply speed of the indoor fan is increased and/or the running frequency of the compressor is reduced, so that condensation prevention treatment is carried out on the air supply outlet. Compared with the anti-condensation treatment method of the air conditioner in the prior art, the technical scheme of the application can prevent condensation from being generated at the air supply outlet of the indoor unit, and the anti-condensation treatment is performed after the condensation is generated at the air supply outlet, so that the aim of improving user experience can be achieved.
The method for performing the condensation preventing treatment on the indoor unit according to the air outlet humidity of the air outlet in the step S4 is described in detail below with reference to the specific embodiment, and it is to be understood that the method described below is exemplary and not limiting, and in other embodiments, the condensation preventing treatment may be performed on the indoor unit according to the air outlet humidity of the air outlet by other methods.
In one embodiment, in the step S4, the method for performing the condensation preventing treatment on the indoor unit according to the air outlet humidity of the air outlet includes:
firstly, generating a corresponding relation among air outlet humidity of an air outlet, air supply speed of an indoor fan and operation frequency of a compressor;
and then, according to the corresponding relation and the air outlet humidity at the air outlet obtained in the step S1, obtaining the corresponding air supply wind speed and the corresponding operating frequency, adjusting the indoor fan according to the obtained air supply wind speed, and adjusting the compressor according to the obtained operating frequency.
In this embodiment, the generated correspondence relationship has the air blowing speed of the optimal indoor fan and the operation frequency of the compressor corresponding to each air outlet humidity. For example, for the air outlet humidity of a certain air outlet, the optimum air outlet speed and the operation frequency corresponding to the air outlet humidity refer to that when the air outlet humidity of the air outlet is the air outlet humidity, if the indoor fan operates at the air outlet speed and the compressor operates at the operation frequency, the air outlet humidity of the air outlet is not greater than the first set humidity, and the air outlet speed of the indoor fan changes minimally, or the operation frequency of the compressor drops minimally, so that the influence of condensation prevention treatment on the refrigerating function or the dehumidifying function of the air conditioner is reduced.
The corresponding relation can be stored in a database on the air conditioner, after the wind outlet degree of the wind outlet is obtained, the database is queried according to the wind outlet degree to obtain the corresponding wind speed and the running frequency of the wind outlet, then the running frequency of the compressor is controlled to be the running frequency, the corresponding fan rotating speed is obtained according to the wind speed of the wind outlet, and the rotating speed of the indoor fan is controlled to be the fan rotating speed.
In one embodiment, the flow of acquiring the humidity of the air outlet at the air outlet in the step S1 is shown in fig. 2, and includes the following steps:
step S201: and detecting the humidity of the air outlet at least two positions of the air supply outlet to obtain the humidity of the air outlet at the at least two positions.
In this embodiment, humidity sensors may be disposed at a plurality of positions of the air supply port, where each position may be uniformly distributed at the air supply port of the indoor unit, or a designer may observe the air supply port during operation of the air conditioner, so as to obtain a plurality of positions where condensation is easily generated in the air supply port, and corresponding humidity sensors are disposed at the plurality of positions, respectively. The signal output ends of the humidity sensors are connected with the air conditioner, so that the air conditioner can detect the air-out humidity of the air outlet of the indoor unit at a plurality of positions and send the air-out humidity to the air conditioner, and the air conditioner can obtain the air-out humidity of the air outlet at a plurality of positions.
Step S202: and taking the maximum one of the air outlet humidity of the at least two positions as the air outlet humidity of the air inlet.
Because the temperatures of the positions of the air supply port may be different, condensation degrees of the positions of the air supply port may be different, if only the air outlet humidity of one position of the air supply port is detected, the indoor condensation prevention treatment cannot be performed when the air outlet humidity of the position is smaller than the first set humidity and the air outlet humidity of other positions is larger than the first set humidity. The setting mode of this embodiment obtains the air outlet humidity of supply-air outlet according to the play rheumatism of a plurality of positions of the supply-air outlet of air conditioner, can prevent can't prevent in time carrying out the anti-condensation to the supply-air outlet because the humidity to the supply-air outlet is missed and is examined to prevent the reliability of anti-condensation to the supply-air outlet.
In one embodiment, in the step S2, obtaining the air outlet humidity of the air outlet of the air conditioner includes: and periodically detecting the air outlet humidity of the air outlet of the air conditioner, namely detecting the air outlet humidity of the air outlet of the air conditioner once every one detection period to obtain the air outlet humidity of the air outlet once. And after the humidity of the air supply outlet is obtained each time, judging whether the air supply outlet needs to be subjected to anti-condensation treatment or not, so that the periodic anti-condensation treatment of the air supply outlet is realized.
By the arrangement mode of the embodiment, whether the anti-condensation treatment is needed for the air supply outlet of the indoor unit can be judged once every one detection period, so that the timeliness of the anti-condensation treatment for the air conditioner is improved.
In one embodiment, the anti-condensation process control method of the present application further comprises: after the air supply speed is increased, if the air outlet rheumatism degree of the air supply port is reduced, the operation frequency of the compressor is increased.
The cooling effect of the air conditioner on the indoor environment is reduced due to the fact that the operation frequency of the compressor is reduced, and after the air supply speed is increased, if the air outlet degree of the air supply port is reduced, the air supply port can be considered to be free from condensation, and at the moment, if the operation frequency of the compressor is continuously reduced, the user experience is affected. Therefore, in the embodiment, when the air outlet air-out degree is reduced, the operation frequency of the compressor is increased, so that the influence on the refrigeration effect caused by the reduction of the operation frequency of the compressor can be avoided, and the purpose of improving the user experience is achieved.
In one embodiment, the anti-condensation control method of the present application further includes a method for determining whether anti-condensation treatment is required for the air supply outlet according to an increasing rate of air outlet humidity of the air supply outlet, and a flow chart of the method is shown in fig. 3, where the method includes:
step S301: and acquiring the rising rate of the air outlet humidity of the air outlet of the air conditioner.
For example, when the air outlet humidity of the air outlet of the air conditioner is periodically obtained, the air outlet humidity obtained in the current period is differentiated from the air outlet humidity value obtained in the previous period to obtain an air outlet humidity difference value between the current period and the previous period, and then the air outlet humidity difference value is compared with the duration of the detection period, wherein the obtained ratio is the rising rate of the air outlet humidity of the air outlet.
Step S302: according to the rising rate of the air outlet humidity of the air outlet, judging whether condensation prevention treatment is needed to be carried out on the air outlet, wherein the judging method can be as follows:
judging whether the rising rate of the air outlet humidity of the air outlet meets a preset condition or not;
if so, the anti-condensation treatment is needed to be carried out on the air supply opening, and the anti-condensation treatment can be used for improving the air supply speed of the indoor fan and/or reducing the operation frequency of the compressor.
In this embodiment, the preset condition may be that an increasing rate of the air outlet humidity of the air outlet is greater than a preset rate, where the preset rate may be a preset value stored in the air conditioner, after the increasing rate of the air outlet humidity of the air outlet is obtained, the preset rate is obtained by a data reading manner, and the obtained increasing rate is compared with the preset rate, so as to determine whether the increasing rate of the air outlet humidity of the air outlet meets the preset condition.
In other embodiments, the preset condition may be that the rising rate of the air outlet humidity of the air outlet is not within the expected range, or the change of the rising rate is not within the expected range, for example, the rising rate of the air outlet humidity of the air outlet of the current detection period is smaller than the preset rate, and the air outlet humidity of the air outlet of the consecutive multiple detection periods before the detection period is smaller than the preset rate, etc.
In this embodiment, whether the anti-condensation treatment is performed is determined according to the rising rate of the air outlet humidity of the air outlet, and because the air outlet still has the risk of condensation when the rising rate of the air outlet humidity of the air outlet satisfies the preset condition even though the air outlet humidity of the air outlet is not greater than the first set humidity. Therefore, in this embodiment, when the rising rate of the air outlet humidity of the air outlet meets the preset condition, the anti-condensation treatment is performed on the air outlet of the air conditioner.
Through the setting mode of this embodiment, can prevent the processing of condensation when there is the risk of condensation to the supply-air outlet, but not remove the processing of dew after the supply-air outlet appears the condensation again, consequently can improve the reliability of preventing the condensation to the supply-air outlet.
In one embodiment, the method for increasing the rotation speed of the indoor fan includes:
and periodically increasing the air supply speed of an indoor fan of the air conditioner, wherein the air supply speed in each period is increased by a preset proportion relative to the air supply speed in the previous period.
Through the setting mode of this embodiment, the air supply wind speed of the indoor fan can be increased by one adjustment period every interval, and when the air supply wind speed of the indoor fan is increased every time, the current air supply wind speed of the indoor fan is firstly obtained, the increasing amount of the air supply wind speed of the indoor fan is obtained according to the current air supply wind speed of the indoor fan, then the target air supply wind speed of the indoor fan is obtained according to the increasing amount and the current air supply wind speed of the indoor fan, and the rotating speed of the indoor fan of the air conditioner is adjusted according to the target air supply wind speed.
For example, let the current air supply speed of the indoor fan of the air conditioner be V, and the increase of the air supply speed of the indoor fan obtained according to the current air supply speed of the indoor fan be aV, where a is a value greater than 0 and less than 1; and then the rotation speed of the indoor unit of the air conditioner is regulated by taking the air supply wind speed as (1+a) V as a target air supply wind speed, so that the air supply wind speed of the indoor fan of the air conditioner is (1+a) V.
Through the setting mode of this embodiment, the air supply wind speed of the indoor fan of the air conditioner can be increased periodically, and the increment of each time is obtained according to the current air supply wind speed of the indoor fan, thereby preventing the air supply wind speed of the indoor unit of the air conditioner from increasing too fast to influence the working performance of the indoor unit, and achieving the purpose of improving the running reliability of the air conditioner.
In one embodiment, the anti-condensation treatment is performed on the air supply opening, including increasing the air supply speed of the indoor fan and reducing the operation frequency of the compressor, and in the process of performing the anti-condensation treatment, when the frequency of the compressor is reduced to a preset frequency, the reduction of the frequency of the compressor is stopped, and the air supply speed of the indoor fan is adjusted to the air supply speed before the increase.
The preset frequency can be the minimum frequency required by the operation of the compressor, when the frequency of the compressor reaches the preset frequency, if the frequency of the compressor is reduced, the compressor cannot work normally, so that the frequency of the compressor stops being reduced when the frequency of the compressor reaches the preset frequency, and the air supply speed of the indoor fan is regulated to the air supply speed before the air supply speed is increased, so that the air conditioner refrigerates the indoor environment.
In one embodiment, the compressor operation refrigeration mode in the step S2 refers to that the air conditioner is in a refrigeration operation state, and a difference between the indoor environment temperature and the set temperature is greater than a preset difference.
The set temperature may be a target temperature that the air conditioner needs to reach when performing cooling, for example, the target temperature may be a temperature set by a user through a remote controller or a control panel of the air conditioner, and the air conditioner performs cooling on an indoor environment with the temperature as a target, so that the indoor environment temperature reaches the target temperature.
When the air conditioner works in a refrigeration working state, if the difference value between the indoor environment temperature and the set temperature is larger than the preset difference value, the indoor environment temperature can be considered to be too high, and the air conditioner needs to be controlled to quickly refrigerate the indoor environment. In the case of rapid cooling, it is necessary to control the frequency rise of the compressor to improve the cooling capacity of the air conditioner. When the frequency of the compressor is increased, the temperature of the inner coil pipe of the indoor unit is reduced, so that the difference between the temperature of the air outlet and the indoor environment temperature is increased, and the risk of condensation at the air outlet is increased.
According to the setting mode of the embodiment, when the air conditioner is in a refrigerating working state and the difference between the indoor environment temperature and the set temperature is larger than the preset difference, the anti-condensation treatment is carried out on the air supply outlet, so that the reliability of the anti-condensation treatment of the air conditioner can be improved.
In one embodiment, the anti-condensation control method of the air conditioner of the present application further includes:
judging whether the humidity of an air outlet of an indoor unit of the air conditioner is less than a second set humidity, wherein the second set humidity is not more than the first set humidity;
if it is smaller than, the frequency of the compressor of the air conditioner is increased.
In this embodiment, if the humidity of the air outlet of the indoor unit is less than the second set humidity, it may be determined that the air supply outlet of the indoor unit does not have a risk of condensation, and at this time, the frequency of the compressor of the air conditioner is increased, so that the refrigerating capacity of the air conditioner may be improved, the requirement of the user on indoor environment refrigeration may be met, and the user experience may be improved.
In one embodiment, the application also provides an air conditioner, which comprises a compressor, an indoor heat exchanger, an indoor fan and a controller, wherein the indoor heat exchanger is connected with the compressor, the indoor heat exchanger and the indoor fan are arranged in an air supply duct, and an air supply outlet of the air supply duct forms an air supply outlet.
