Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular, to an air conditioner odor control method, an air conditioner applying the air conditioner odor control method, and a computer readable storage medium applying the air conditioner odor control method. BACKGROUND

[0002] At present, the antifungal and antibacterial coating on the surface of the evaporator may be partially damaged due to friction, handling or changes in environmental humidity before the air conditioner is shipped or during transportation, and the damaged area is easy to adsorb organic matter (such as grease, dust mite metabolites, volatile organic compounds VOCs, etc.) in the air, which gradually releases odor molecules (such as aldehydes, ketones, sulfides, etc.) in subsequent use, thereby causing user complaints about air conditioner odor.

[0003] In order to control the air conditioner odor, in a control method for preventing the air conditioner indoor unit from blowing out odor, the evaporator is lowered below the dew point temperature to precipitate water droplets and form a water film, which completely covers the surface of the evaporator fins to avoid the air conditioner indoor unit blowing out the unpleasant smell on the evaporator fins. However, this scheme forms a water film by generating condensate water, which is easy to distribute unevenly, with some parts being relatively dry and some parts having more moisture, and odor molecules are easy to stay on the fins. At the same time, the process of generating condensate water is slow, and the odor removal response is slow.

[0004] Therefore, a more optimized air conditioner odor control method needs to be considered. SUMMARY

[0005] The first object of the present application is to provide an air conditioner odor control method capable of preventing uneven distribution of water film on the surface of indoor heat exchanger and improving odor removal response speed.

[0006] The second object of the present application is to provide an air conditioner capable of preventing uneven distribution of water film on the surface of indoor heat exchanger and improving odor removal response speed.

[0007] The third object of the present application is to provide a computer readable storage medium capable of preventing uneven distribution of water film on the surface of indoor heat exchanger and improving odor removal response speed.

[0008] In order to achieve the above-mentioned first object, the air conditioner odor control method provided by the present application comprises: acquiring the odor concentration value of the air conditioner indoor unit outlet every interval preset time length when the air conditioner enters the refrigeration mode or the air supply mode; if the current odor concentration value of the current period is greater than the odor concentration value at the indoor fan start time, controlling the water spraying device to spray water to the indoor heat exchanger to form a water film covering the surface of the indoor heat exchanger.

[0009] From the above scheme can be seen, the air conditioner odor control method of the present application by setting water spraying device, when the current cycle of the current odor concentration value is greater than the odor concentration value at the indoor fan starting time, by spraying water to form a stable water film, using water molecules on the physical adsorption and solvent effect of odor molecules, reduce its volatility and activity, thereby inhibiting the release of odor. At the same time, the water spraying can make the water on the evaporator surface form a flowing whole, keep the uniformity of the evaporator surface wet, inhibit the odor molecule volatilization, and, using water spraying to form a water film, the water film forming speed is fast, can improve the response speed of deodorization.

[0010] In further schemes, the step of controlling the water spraying device to spray water to the indoor heat exchanger to form a water film covering the surface of the indoor heat exchanger comprises: obtaining a current water spraying amount according to the current odor concentration value; controlling the water spraying device to spray water according to the current water spraying amount.

[0011] It can be seen that, by obtaining the current water spraying amount according to the current odor concentration value, the water spraying amount can be reasonably controlled to avoid excessive or insufficient water spraying.

[0012] In further schemes, the step of obtaining the current water spraying amount according to the current odor concentration value comprises: calculating a recommended water spraying amount according to at least one of the current odor concentration value, a fin pitch value of the indoor heat exchanger, a fin thickness value of the indoor heat exchanger, a fin density value of the indoor heat exchanger, a preset nozzle coefficient of the water spraying device, and a current wind range correction coefficient of the indoor fan; obtaining the current water spraying amount according to the recommended water spraying amount.

[0013] In further schemes, the recommended water spraying amount is obtained by the following formula: Q0=k×S×T×N×f+F; f=1+0.5×(C-50) / 100; wherein Q0 is the recommended water spraying amount, k is the preset nozzle coefficient, S is the fin pitch value, T is the fin thickness value, N is the fin density value, F is the current wind range correction coefficient, f is the concentration feedback function, and C is the current odor concentration value.

[0014] It can be seen that, by calculating the reasonable water spraying amount according to the current odor concentration value, the fin pitch value of the indoor heat exchanger, the fin thickness value of the indoor heat exchanger, the fin density value of the indoor heat exchanger, the preset nozzle coefficient of the water spraying device, and the current wind range correction coefficient of the indoor fan, the system can maintain the optimal purification efficiency under different fin structures.

[0015] In further schemes, the step of obtaining the current water spraying amount according to the recommended water spraying amount comprises: multiplying the correction coefficient corresponding to the current odor concentration value by the recommended water spraying amount to obtain the current water spraying amount.

[0016] It can be seen that, by using the correction coefficient corresponding to the current odor concentration value to correct the recommended water spraying amount, the water amount control can be optimized, and the control accuracy can be improved.

[0017] In a further proposed solution, the correction coefficient corresponding to the current odor concentration value is positively correlated with the current odor concentration value.

[0018] Therefore, setting a correction coefficient according to the current odor concentration value can improve the rationality of the correction coefficient. When the current odor concentration value is low, a smaller correction coefficient can be used to save water, and when the current odor concentration value is high, a larger correction coefficient can be used to enhance the odor removal effect.

[0019] In a further embodiment, the spray nozzles of the water spray device are movably installed on the indoor unit of the air conditioner; the step of controlling the water spray device to spray water onto the indoor heat exchanger to form a water film covering the surface of the indoor heat exchanger includes: controlling the spray nozzles to spray the surface of the indoor heat exchanger evenly.

[0020] Therefore, by controlling the nozzles to spray the surface of the indoor heat exchanger evenly, the uniformity of the water film formation can be improved, thus enhancing the deodorization effect.

[0021] In a further embodiment, when controlling the water spraying device to spray water onto the indoor heat exchanger to form a water film covering the surface of the indoor heat exchanger, the method further includes: obtaining the corresponding fresh air fan speed based on the odor concentration range of the current odor concentration value; and controlling the operation of the fresh air fan based on the fresh air fan speed.

[0022] Therefore, controlling the speed of the fresh air fan according to the current odor concentration can further reduce odor and at the same time, reasonably control energy consumption.

[0023] In a further proposed solution, the rotational speed of the fresh air fan is positively correlated with the current odor concentration.

[0024] Therefore, it can be seen that the speed of the fresh air fan increases with the increase of the current odor concentration, which can improve the odor removal effect.

[0025] In a further proposed solution, the step of obtaining the corresponding fresh air fan speed based on the odor concentration range of the current odor concentration value includes: obtaining the cumulative number of times the water spray device is activated during the current cooling mode or the current air supply mode; and calculating the fresh air fan speed based on the cumulative number of water spray activations.

[0026] Therefore, if the water spray is activated multiple times, it indicates that the odor removal is not thorough enough. Thus, the fresh air fan speed is calculated based on the cumulative number of water spray activations to improve the odor removal effect.

[0027] In a further proposed solution, the rotational speed of the fresh air fan is positively correlated with the cumulative number of times the water spray has been activated.

[0028] Therefore, the more times the water spray is activated, the higher the odor concentration, and the higher the speed of the fresh air fan is required to reduce the odor.

[0029] To achieve the second object of the present application, the present application provides an air conditioner comprising a processor and a memory, the memory storing a computer program, the computer program being executed by the processor to implement the steps of the air conditioner odor control method.

[0030] To achieve the third object of the present application, the present application provides a computer readable storage medium, which stores a computer program, the computer program being executed by a controller to implement the steps of the air conditioner odor control method.

[0043] Techniques, methods, and equipment known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered as part of the specification where appropriate.

[0044] Air conditioner odor control method embodiments: The air conditioner odor control method of the present application is an application program applied in an air conditioner, for controlling odor of an air conditioner indoor unit.

[0045] In this embodiment, referring to Figure 1 , the air conditioner indoor unit includes an indoor heat exchanger 1 and a water spraying device 2, and the water spraying device 2 is used to spray water to the surface of the indoor heat exchanger 1.

[0046] Referring to Figure 2 The water spraying device 2 comprises a spraying head 21, a guide rail 22, a driving motor 23 and a water inlet pipe 24. The spraying head 21 is mounted on the guide rail 22, the guide rail 22 is arranged along the top to bottom of the indoor heat exchanger 1, and the driving motor 23 is used to drive the spraying head 21 to move along the guide rail 22. The water inlet pipe 24 is communicated with the water inlet end of the spraying head 21. Preferably, the spraying head 21 adopts a spraying type spraying head to save water.

[0047] In addition, an odor molecule concentration sensor (not shown) is arranged at the air outlet of the air conditioner indoor unit, and is used to detect the odor concentration value at the air outlet. The odor molecule concentration sensor adopts a device known to those skilled in the art, and will not be described here.

[0048] Referring to Figure 3 The odor control method of the air conditioner of the embodiment is used in work, first executes step S1, judges whether the air conditioner enters the refrigeration mode or the air supply mode operation. Mold is easy to breed in humid and cold environment, and when refrigeration or air supply, the evaporator is relatively cold and humid, which is conducive to the breeding of mold, therefore, it is necessary to carry out odor control in the refrigeration mode or the air supply mode operation.

[0049] When the air conditioner enters the refrigeration mode or the air supply mode operation, step S2 is executed, and the odor concentration value of the air outlet of the air conditioner indoor unit is obtained once every preset time length. Among them, the preset time length can be set in advance according to experimental data, for example, the preset time length is 30 minutes. Preferably, the odor concentration value can be detected for multiple times within the preset time length, and the average odor concentration value within the preset time length is taken as the odor concentration value of the current period, so as to improve the accuracy of the odor concentration value.

[0050] After obtaining the odor concentration value of the air outlet of the air conditioner indoor unit, step S3 is executed, and it is judged whether the current odor concentration value of the current period is greater than the odor concentration value at the starting time of the indoor fan. In order to determine whether the odor is caused by the breeding of mold or the damage of the raw material coating of the indoor heat exchanger, it is necessary to compare and confirm the current odor concentration value of the current period and the odor concentration value at the starting time of the indoor fan.

[0051] If the current odor concentration value of the current period is less than or equal to the odor concentration value at the starting time of the indoor fan, the air conditioner is normally operated, and the step S2 is continuously performed to detect the odor. The current odor concentration value is less than or equal to the odor concentration value at the starting time of the indoor fan, which indicates that the raw material coating of the indoor heat exchanger is not damaged at this time. The odor rate is large at the air conditioner starting stage, which is mainly caused by the microorganism breeding due to the incomplete drying of the fins. When the air conditioner is turned off, the residual condensate in the evaporator is a humid environment, and the bacteria continuously breed in the evaporator fins and filter screen to produce odor. When the air conditioner is started, these odors are blown out at high speed, so that the odor concentration value decreases after the air conditioner is operated for a period of time. At this time, the water spraying operation is not required to control the odor.

[0052] If the current odor concentration value of the current period is greater than the odor concentration value at the starting time of the indoor fan, the step S4 is performed to control the water spraying device 2 to spray water to the indoor heat exchanger 1 to form a water film covering the surface of the indoor heat exchanger 1. After the coating of the indoor heat exchanger 1 is damaged, the exposed metal such as aluminum and copper will cause electrochemical corrosion to release metal odor or acid odor. In this case, the longer the operation time, the more serious the corrosion, and the heavier the odor. Therefore, the mold at the air conditioner starting stage is biological pollution, and there is biological pollution and chemical pollution after the coating of the indoor heat exchanger 1 is damaged. The current odor concentration value is greater than the odor concentration value at the starting time of the indoor fan, which indicates that the odor caused by the decomposition of the damaged raw material aluminum foil coating of the indoor heat exchanger 1 appears at this time. At this time, the water spraying device needs to be started to spray water to form a water film to control the odor.

[0053] In this embodiment, referring to Figure 4 When the water spraying device 2 is controlled to spray water to the indoor heat exchanger 1 to form a water film covering the surface of the indoor heat exchanger 1, the step S11 is first performed to obtain the current water spraying amount according to the current odor concentration value. In order to reasonably control the water consumption and save water resources, the current odor concentration value is required to correspond to the control of the water spraying amount.

[0054] In this embodiment, referring to Figure 5In the step S21, the recommended water spraying amount is calculated according to at least one of the current odor concentration value, the fin pitch value of the indoor heat exchanger 1, the fin thickness value of the indoor heat exchanger 1, the fin density value of the indoor heat exchanger 1, the preset nozzle coefficient of the water spraying device 2, and the current wind level correction coefficient of the indoor fan. Preferably, the recommended water spraying amount is obtained by the following formula: Q0=k×S×T×N×f+F; f=1+0.5×(C-50) / 100; wherein Q0 is the recommended water spraying amount (mL), k is the preset nozzle coefficient, S is the fin pitch value (mm), T is the fin thickness value (mm), N is the fin density value (pieces / mm), F is the current wind level correction coefficient, f is the concentration feedback function, and C is the current odor concentration value (ppb). It should be noted that the calculation formula of the recommended water spraying amount only uses the numerical values of the parameters.

[0055] The reasonable water spraying amount is calculated according to the current odor concentration value, the fin pitch value of the indoor heat exchanger 1, the fin thickness value of the indoor heat exchanger 1, the fin density value of the indoor heat exchanger 1, the preset nozzle coefficient of the water spraying device 2, and the current wind level correction coefficient of the indoor fan, so that the system can maintain the optimal purification efficiency under different fin structures. The fin pitch value of the indoor heat exchanger 1, the fin thickness value of the indoor heat exchanger 1, the fin density value of the indoor heat exchanger 1, and the preset nozzle coefficient of the water spraying device 2 can be pre-set according to the indoor heat exchanger 1. The current wind level correction coefficient can be obtained by looking up the table according to the current wind level, for example, when the current wind level is the low wind level, the current wind level correction coefficient is 0.8, and when the current wind level is the medium wind level, the current wind level correction coefficient is 1.6.

[0056] After obtaining the recommended water spraying amount, the step S22 is performed to obtain the current water spraying amount according to the recommended water spraying amount. By using the recommended water spraying amount to obtain the current water spraying amount, the accuracy of the water spraying amount can be improved.

[0057] In this embodiment, the step of obtaining the current water spraying amount according to the recommended water spraying amount includes multiplying the correction coefficient corresponding to the current odor concentration value by the recommended water spraying amount to obtain the current water spraying amount. By using the correction coefficient corresponding to the current odor concentration value to correct the recommended water spraying amount, the water amount control can be optimized, and the control accuracy can be improved.

[0058] The correction coefficient corresponding to the current odor concentration value is positively correlated with the current odor concentration value. The correction coefficient corresponding to the current odor concentration value can be pre-set according to experimental data. The correction coefficient is set according to the size of the current odor concentration value, which can improve the rationality of the correction coefficient. When the current odor concentration value is small, a smaller correction coefficient can be used to save water. When the current odor concentration value is large, a larger correction coefficient can be used to enhance the odor removal effect. For example, if the current odor concentration value is in the range of C<50ppb, the current water spraying amount is Q=Q0×0.8; if the current odor concentration value is in the range of 50≤C<100ppb, the current water spraying amount is Q=Q0×1.0; if the current odor concentration value is in the range of C≥100ppb, the current water spraying amount is Q=Q0×1.5.

[0059] In an optional embodiment, if the calculated current water spraying amount Q<0.5mL, the current water spraying amount is adjusted to 0.5mL to prevent invalid water spraying. If the current water spraying amount Q>3.0mL, the current water spraying amount is sprayed twice by controlling the water spraying device 2 to move from the top to the bottom of the indoor heat exchanger 1 and then from the bottom to the top of the indoor heat exchanger 1 to avoid local over-wetting.

[0060] After obtaining the current water spraying amount, step S12 is performed to control the water spraying device 2 to spray water according to the current water spraying amount. By obtaining the current water spraying amount according to the current odor concentration value, the water spraying amount can be reasonably controlled to avoid excessive or insufficient water spraying.

[0061] In this embodiment, the nozzle 21 of the water spraying device 2 is movably installed on the air conditioner indoor unit. When the water spraying device 2 is controlled to spray water onto the indoor heat exchanger 1 to form a water film covering the surface of the indoor heat exchanger 1, the nozzle 21 is also controlled to uniformly spray the surface of the indoor heat exchanger 1. When the nozzle 21 is controlled to uniformly spray, the nozzle 21 can be controlled to move at a constant speed on the guide rail 22 in a direction from the top to the bottom of the indoor heat exchanger 1. By controlling the nozzle 21 to uniformly spray the surface of the indoor heat exchanger 1, the uniformity of the water film formed can be improved, and the odor removal effect can be improved.

[0062] In this embodiment, referring to Figure 6 When the water spraying device 2 is controlled to spray water onto the indoor heat exchanger 1 to form a water film covering the surface of the indoor heat exchanger 1, step S31 is also performed to obtain the corresponding fresh air fan speed according to the range of the current odor concentration value. When the water spraying device 2 is controlled, the fresh air fan speed is controlled according to the current odor concentration value, which can further reduce the odor and reasonably control the energy consumption. The fresh air fan speed is positively correlated with the current odor concentration value. The fresh air fan speed increases with the increase of the current odor concentration value, which can improve the effect of removing odor.

[0063] In this embodiment, referring to Figure 7 , when the corresponding fresh air fan speed is obtained according to the odor concentration value range in which the current odor concentration value is located, step S41 is performed first to obtain the cumulative water spraying times of the water spraying device 2 during the current refrigeration mode or the current air supply mode. If there are multiple water spraying times, it indicates that the odor removal is not thorough enough, and therefore the fresh air fan speed is calculated by the cumulative water spraying times, so as to improve the odor removal effect.

[0064] After the cumulative water spraying times are obtained, step S42 is performed to calculate the fresh air fan speed according to the cumulative water spraying times. The fresh air fan speed is positively correlated with the cumulative water spraying times. The more the cumulative water spraying times are, the greater the odor concentration is, and the greater the required fresh air fan speed is, so as to reduce the odor. In the air supply mode, the opening of the fresh air fan has little effect on the air outlet temperature of the air conditioner, and the running speed of the fresh air fan can be higher. In the refrigeration mode, the opening of the fresh air fan has a greater effect on the air outlet temperature of the air conditioner, and the running speed of the fresh air fan needs to be lower, and therefore the fresh air fan speed in the refrigeration mode is smaller than that in the air supply mode under the same current odor concentration value. Specifically, the fresh air fan speed in the refrigeration mode and the air supply mode is obtained in the following table, in which n is the cumulative water spraying times:

[0065] After the corresponding fresh air fan speed is obtained, step S32 is performed to control the fresh air fan to run according to the fresh air fan speed. By controlling the fresh air fan to run at the fresh air fan speed, the fresh air fan speed can be ensured to be in a reasonable working state, and the energy consumption can be saved.

[0066] As can be seen from the above scheme, the odor control method of the air conditioner of the present application can form a stable water film by spraying water when the current odor concentration value in the current period is greater than the odor concentration value at the indoor fan starting time, and can reduce the volatility and activity of odor molecules by using the physical adsorption and solvent effect of water molecules on odor molecules, so as to inhibit the release of odor. At the same time, the water on the evaporator surface can form a whole flow by spraying, so as to maintain the uniformity of the evaporator surface humidity, inhibit the volatilization of odor molecules, and improve the odor removal response speed by forming a water film by spraying.
