Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.
In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of the present disclosure. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure. Embodiments of the present disclosure are described in detail below with reference to the attached drawings.
The air conditioner control method provided by the embodiment of the disclosure can be applied to a scene of executing a fresh air function through a fresh air device of an air conditioner.
With the improvement of the living standard of people, the air conditioner becomes an indispensable electrical appliance in the life of people.
In the related art, an air conditioner is generally located in a closed place when in operation. In order to prevent users in a closed place from feeling oppressed, the air conditioner may take fresh air from outdoors to be delivered indoors. For example, a fresh air function of the air conditioner is turned on, and outdoor air is extracted by a fan of the fresh air device to be delivered indoors through a fresh air pipeline. In the process that the air conditioner executes the fresh air function through the fresh air device, condensation phenomenon usually occurs in the interior or the exterior of the fresh air pipeline due to unequal indoor and outdoor environment parameters. For example, when the outdoor temperature is lower than the indoor temperature and the indoor air humidity is high, the condensation phenomenon is easy to occur outside the fresh air pipeline. For example, when the indoor temperature is lower than the outdoor temperature and the outdoor air humidity is high, the condensation phenomenon is easy to occur in the fresh air pipeline. In the related art, if the fresh air pipeline is exposed, the problems of air conditioner leakage or short circuit of air conditioning equipment and the like may occur, so that the air conditioner is damaged.
In the related art, the ambient temperature and the ambient humidity can be monitored, and the fan of the fresh air device is turned off when the current ambient temperature and the current ambient humidity are determined to have condensation risks. Although the method of closing the fan in the related art can improve the problem of condensation of the fresh air pipeline, the method cannot enable a user to continuously use the fresh air function of the air conditioner, and the user experience is poor.
The present disclosure provides an air conditioner control method, which can determine a critical fan rotation speed matching a current environmental parameter through the current environmental parameter of an air conditioner. The critical fan rotating speed meets the condition that when a fan of a fresh air device of the air conditioner works at a rotating speed greater than the critical fan rotating speed under the current environmental parameters, condensation occurs in a fresh air pipeline in the fresh air device. Further, the current fan rotating speed of the fresh air device can be adjusted through the critical fan rotating speed. The method adjusts the current fan rotating speed through the critical fan rotating speed, and the fan is directly closed in a 'one-cut' mode, so that the condensation problem of a fresh air pipeline can be solved while the fresh air function is ensured, the method is more suitable for actual use requirements, and the use experience of a user can be improved.
Fig. 1 is a flowchart illustrating a control method of an air conditioner according to an exemplary embodiment, as shown in fig. 1, including the following steps.
In step S11, a current environmental parameter of the air conditioner is determined.
In the embodiment of the disclosure, the current environmental parameter of the air conditioner may be understood as an environmental parameter of the current environment in which the air conditioner is located.
In step S12, a critical fan speed is determined that matches the current environmental parameters.
The critical fan rotating speed meets the condition that when a fan of a fresh air device of the air conditioner works at a rotating speed greater than the critical fan rotating speed under the current environmental parameters, condensation occurs in a fresh air pipeline in the fresh air device. For example, if the fan of the fresh air device is operated at a rotational speed greater than the critical fan under the current environmental parameters, condensation may occur in the fresh air line of the fresh air device.
In step S13, the current fan speed of the fresh air device is adjusted based on the critical fan speed.
According to the air conditioner control method provided by the embodiment of the disclosure, the current fan rotating speed of the fresh air device can be adjusted through the critical fan rotating speed, and the method can be used for dynamically adjusting the fan rotating speed by taking the critical fan rotating speed as a reference. Further, under the condition that the current environmental parameters are determined, the fresh air function can be executed by the adjusted rotating speed of the fan, and the use experience of a user is improved.
In the disclosed embodiments, the current environmental parameters may include, for example, a current ambient temperature and a current ambient relative humidity. By way of example, the dew point temperature and the absolute moisture content of the air can be determined by the current ambient temperature and the current ambient relative humidity, and the critical fan speed can be determined by the ambient temperature, the dew point temperature and the absolute moisture content of the air.
Fig. 2 is a flowchart of another air conditioner control method according to an exemplary embodiment, and as shown in fig. 2, step S21 and step S24 in the embodiment of the disclosure are similar to the implementation process of step S11 and step S13 in fig. 1, and are not described herein.
In step S22, the dew point temperature and the absolute moisture content of the air are determined based on the ambient temperature and the current ambient relative humidity.
In step S23, a critical fan speed is determined based on the ambient temperature, the dew point temperature, and the absolute moisture content of the air.
According to the air conditioner control method provided by the embodiment of the disclosure, the critical fan rotating speed matched with the current environment parameter can be obtained through the current environment temperature, the dew point temperature and the absolute moisture content of air, and the critical fan rotating speed is taken as a reference value to regulate the current fan rotating speed, so that the problem that condensation occurs in a fresh air pipeline while the normal execution of a fresh air function is ensured is solved.
By way of example, it is possible toThe dew point temperature (example denoted by T _ d) is determined. Wherein a and b are preset constants for adjusting the range of the dew point temperature, and lambda is an intermediate quantity for representing the indirect relationship between the dew point temperature and the environment relative humidity and the environment temperature. By way of example, it is possible toThe intermediate quantity lambda is determined by means of (a). Wherein T represents the ambient temperature and U represents the ambient relative humidity. In addition, the range of the environmental relative humidity is 0-100, so the ratio of the environmental relative humidity to 100 can approximately represent the humidity state of the current environment of the air conditioner heat exchanger. In the embodiment of the present disclosure, the preset constant a may be set to 17.27 and the preset constant b may be set to 237.7. Of course, the preset constant may be set to other values according to actual requirements, and the setting value of the preset constant is not specifically limited in the disclosure.
By way of example, it is possible toIn the above, the absolute moisture content of air (shown in example as d) is determined. Wherein Pw represents the partial pressure of ambient water vapor. In one embodiment, the partial pressure Pw of ambient water vapor can be determined by the ambient temperature of the current environment of the air conditioner and the relative humidity of the current environment of the air conditioner. For example, the ambient water vapor partial pressure Pw may be determined by pw= (0.0808T 3-1.0435T2 +91.38t+309.45) ×u. Wherein T represents the ambient temperature and U represents the ambient relative humidity.
In addition, in the process of determining the dew point temperature and the absolute moisture content of the air, the ambient temperature T and the ambient relative humidity U used can be detected by corresponding detecting elements disposed in the air conditioner. For example, the ambient temperature of the environment in which the air conditioner is currently located may be detected by a temperature detection element (e.g., a thermometer) disposed in the air conditioner. For another example, the relative humidity of the environment in which the air conditioner is currently located may be detected by a humidity detection element (e.g., a hygrometer) disposed in the air conditioner. In addition, the ambient temperature and/or the ambient relative humidity sent by the server may also be received by subscribing to the server. In one embodiment, an environmental parameter subscription request may be initiated to a site, such as a weather station, that may provide environmental parameter monitoring services, and after successful subscription, the environmental parameters sent by the weather station may be periodically received. For example, the air conditioner may initiate a subscription request to the weather station and periodically receive the outdoor ambient temperature and/or the outdoor ambient relative humidity sent by the weather station. Of course, the environmental parameters may be obtained in other manners, which are not specifically limited by the present disclosure.
In one embodiment, the adjustment parameters for adjusting the fan speed can be determined by the ambient temperature, the dew point temperature and the absolute moisture content of the air, and the critical fan speed can be determined by the adjustment parameters.
Fig. 3 is a flowchart illustrating yet another air conditioner control method according to an exemplary embodiment, and as shown in fig. 3, steps S31, S32 and S35 of the embodiment of the present disclosure are similar to the implementation process of steps S21, S22 and S24 in fig. 2, and are not described herein.
In step S33, an adjustment parameter for adjusting the fan rotational speed is determined based on the ambient temperature, the dew point temperature, and the absolute air moisture content.
In step S34, a critical fan speed is determined based on the adjustment parameter and the maximum fan speed.
According to the air conditioner control method provided by the embodiment of the disclosure, the adjusting parameters for adjusting the rotating speed of the fan can be determined through the ambient temperature, the dew point temperature and the absolute moisture content of air, and the critical fan rotating speed is determined through the adjusting parameters. Further, the current fan rotating speed is adjusted according to the critical fan rotating speed, so that the condensation phenomenon is improved when the fan works at the adjusted fan rotating speed, and the fresh air function is normally executed.
For example, the adjustment parameter may be determined as follows.
For convenience of description, a parameter obtained by a difference between a dew point temperature and an ambient temperature, and a preset dew point temperature difference is referred to as a first parameter, and a parameter obtained by an absolute air moisture content and a preset absolute air moisture content compensation parameter is referred to as a second parameter.
FIG. 4 is a flowchart illustrating a method for determining an adjustment parameter for adjusting a fan speed based on an ambient temperature, a dew point temperature, and an absolute moisture content of air, according to an exemplary embodiment, as shown in FIG. 4, including the following steps.
In step S41, a difference between the dew point temperature and the ambient temperature is determined, and a first parameter is determined based on the difference and a preset dew point temperature difference.
The dew temperature difference is a temperature difference between a preset ambient temperature and a preset ambient dew point temperature, and can be understood as an upper limit value for the temperature difference between the ambient temperature and the ambient dew point temperature. If the temperature difference between the ambient temperature and the ambient dew point temperature is greater than the preset dew point temperature difference, the fresh air pipeline may be subjected to the dew condensation phenomenon.
In step S42, a second parameter is determined from the absolute air moisture content and a predetermined absolute air moisture content compensation parameter.
The preset air absolute humidity compensation parameter can be understood as an upper limit value for the air absolute humidity. If the absolute moisture content of the air exceeds the preset absolute moisture content compensation parameter of the air, the fresh air pipeline may be exposed.
In step S43, an adjustment parameter for adjusting the fan rotational speed is determined based on the first parameter and the second parameter.
In the embodiment of the disclosure, a first parameter matched with the current dew point temperature and the ambient temperature and a second parameter matched with the absolute moisture content of air can be respectively determined, and then an adjustment parameter is determined through the first parameter and the second parameter.
For example, the first parameter may be determined byThe representation, where t_d represents the dew point temperature, T represents the ambient temperature, and T Δ represents the preset dew point temperature difference (for example, the preset dew point temperature T Δ may be 20). The second parameter can be passed/>And d represents the absolute air moisture content, and d_set represents a preset air absolute moisture content compensation parameter. Further, the adjustment parameters can be obtained by combining the first parameter and the second parameter. For example, a first parameter (exemplified by/>Representation) and a second parameter (example/>Representation) to/>The way of (2) obtaining the adjustment parameters.
Further, in the case of obtaining the adjustment parameter, the adjustment parameter may be obtained by In (c) a critical fan speed (shown in r cal for example) is obtained. Wherein r max represents the maximum fan speed,/>And a second parameter is represented, m represents a preset temperature compensation parameter, and the second parameter is used for compensating the difference between the dew point temperature and the ambient temperature. Based on this, the compensated first parameter can be passed/>And (3) representing. Furthermore,/>And the value range of the critical fan speed r_cal is used for adjusting the value range of the critical fan speed r_cal so that the value of the critical fan speed r_cal is smaller than or equal to the maximum fan speed r max. For example, if T_d-T-m < 0, then r_cal=r max, and if T_d-T-m is ≡0, then r_cal < r max. Based on this, adjusting the current fan speed at a critical fan speed r_cal that is less than or equal to the maximum fan speed r max may reduce the computational cost of performing further calculations.
In the embodiment of the disclosure, when the air conditioner executes a fresh air function through the fresh air device, the current environment of the air conditioner comprises an indoor environment and an outdoor environment. Thus, the ambient temperature may include an indoor ambient temperature and an outdoor ambient temperature, the dew point temperature may include an indoor dew point temperature and an outdoor dew point temperature, and the absolute humidity of air may include an absolute humidity of indoor air and an absolute humidity of outdoor air. And, because the condensation phenomenon of new trend pipeline divides into the outside condensation of new trend pipeline and the inside condensation of new trend pipeline. Therefore, by way of example, the type of condensation that may occur at present may be determined through a temperature comparison result between the outdoor ambient temperature and the indoor ambient temperature, so as to match the ambient parameters of the type of condensation, and obtain the critical fresh air rotational speed.
For example, for the case where the outdoor ambient temperature is lower than the indoor ambient temperature, the critical fan speed may be determined by the outdoor dew point temperature, the indoor ambient temperature, and the absolute moisture content of the outdoor air.
For another example, for the case where the outdoor ambient temperature is higher than the indoor ambient temperature, the critical fan speed may be determined by the indoor dew point temperature, the outdoor ambient temperature, and the absolute humidity of the indoor air.

In step S53a, if the outdoor ambient temperature is greater than the indoor ambient temperature, the critical fan speed is determined based on the outdoor dew point temperature, the indoor ambient temperature, and the absolute moisture content of the outdoor air.
For example, if the outdoor ambient temperature is greater than the indoor ambient temperature, it may be determined by
In the illustrated embodiment, a critical fan speed (represented by r_cal, for example) is determined. Where t_d_out represents the outdoor dew point temperature, t_in represents the indoor ambient temperature, and d_out represents the absolute moisture content of the outdoor air. Furthermore, a represents a tube exposure compensation parameter, which may be set to 4, for example.
In step S53b, if the outdoor ambient temperature is less than or equal to the indoor ambient temperature, the critical fan speed is determined based on the indoor dew point temperature, the outdoor ambient temperature, and the absolute moisture content of the indoor air.
For example, if the outdoor ambient temperature is less than or equal to the indoor ambient temperature, it may be determined by
In the illustrated embodiment, a critical fan speed (represented by r_cal, for example) is determined. Where t_d_in represents the indoor dew point temperature, t_out represents the outdoor ambient temperature, and d_in represents the absolute moisture content of the indoor air. In addition, b represents a tube exposure compensation parameter, which may be set to 7.5, for example.
In the above embodiments, for fresh air lines, the temperature compensation parameters required to calculate the critical fan speed are typically different due to the pipe exterior condensation compared to the pipe interior condensation. Therefore, the accuracy of the calculated result value of the critical fan rotating speed can be ensured by setting the pipe outer condensation compensation parameter (shown as b in the example) for the pipe outer condensation and setting the pipe inner condensation compensation parameter (shown as a in the example) for the pipe inner condensation, so that the adjusting precision for the fan rotating speed can be improved.
For example, it may be determined whether the air conditioner currently satisfies a condition for improving the condensation phenomenon in a manner of adjusting the rotation speed of the blower.
In one embodiment, a fan rotation speed adjustment mode in which the fresh air device is set can be detected, and a critical fan rotation speed is determined under the condition that the fresh air device is determined to be set to automatically adjust the fan rotation speed, so that the current fan rotation speed is adjusted through the critical fan rotation speed.

In step S62, in the case that it is determined that the fresh air device is set to automatically adjust the fan speed and the current outdoor ambient temperature is within the preset temperature range, a critical fan speed matching the current ambient parameter is determined.
The preset temperature range may be determined by a variation range of indoor environment temperature.
For example, in the case where the variation range of the indoor environment temperature is determined, the indoor environment temperature minimum value within the variation range may be determined, and the indoor environment temperature maximum value within the variation range may be determined. Further, for the minimum indoor environment temperature and the maximum indoor environment temperature, outdoor environment temperature meeting the requirement of improving the condensation phenomenon in a mode of adjusting the rotating speed of the fan is respectively determined, so that the maximum value and the minimum value of a preset temperature range are obtained, and the preset temperature range is further obtained.
By the air conditioner control method provided by the embodiment of the disclosure, whether the fresh air device is currently used for automatically adjusting the rotating speed of the fan or not and whether the current outdoor environment temperature is in a preset temperature range or not can be judged in advance. Based on this, can realize only confirming that new trend device is set up as automatically regulated fan rotational speed, and current outdoor ambient temperature is in the condition of predetermineeing the temperature range, carry out follow-up procedure, can reduce the invalid regulation to the fan rotational speed, when reducing the consumption, laminating actual in-service use demand.
In addition, in the embodiment of the present disclosure, the current fan rotation speed may be adjusted only for a specific scenario in which the condensation phenomenon needs to be improved by adjusting the fan rotation speed. For example, the current fan speed may be adjusted if it is determined that the fresh air device is activated based on a fresh air function trigger. For another example, the current fan rotation speed may be adjusted when it is monitored that the temperature difference between the current outdoor environment temperature and the current indoor environment temperature exceeds a preset threshold value during the operation of the fresh air device.
Fig. 7 is a flowchart of another air conditioner control method according to an exemplary embodiment, and as shown in fig. 7, step S71 and step S73 in the embodiment of the present disclosure are similar to the implementation process of step S11 and step S13 in fig. 1, and are not described herein.
In step S72, if it is determined that the fresh air device is started based on the triggering of the fresh air function, or if it is monitored that the temperature difference value between the current outdoor environment temperature and the current indoor environment temperature exceeds the preset threshold value during the operation of the fresh air device, the critical fan speed matching the current environment parameter is determined.
According to the air conditioner control method provided by the embodiment of the disclosure, the current fan rotating speed can be adjusted only for specific scenes in which the condensation phenomenon needs to be improved in a mode of adjusting the fan rotating speed, when the environmental parameters of the current environment of the air conditioner change slightly, the calculation of the critical fan rotating speed cannot be carried out again, the current fan rotating speed is adjusted, the calculation cost caused by calculating the critical fan rotating speed in real time and adjusting the current fan rotating speed can be reduced, and the power consumption can be reduced.
For example, when determining the critical fan speed that matches the current environmental parameter, the current fan speed of the fresh air device may be adjusted in the following manner.
Fig. 8 is a flowchart of yet another air conditioner control method according to an exemplary embodiment, and as shown in fig. 8, step S81 and step S82 of the embodiment of the present disclosure are similar to the implementation process of step S11 and step S12 of fig. 1, and are not described herein.

In step S83b, if the critical fan speed is greater than the minimum fan speed of the fan and less than or equal to the current fan speed, the fan speed of the fan is adjusted from the current fan speed to the critical fan speed.
In step S83c, if the critical fan speed is greater than the current fan speed, the current fan speed is maintained.
Of course, the current fan speed can be adjusted to the critical fan speed according to the actual demand.
In the embodiment of the disclosure, under the condition that the critical fan speed is greater than the minimum fan speed, the current fan speed can be adaptively adjusted within a fan speed adjusting range from the minimum fan speed to the critical fan speed. Because only aiming at the condition that the current fan rotating speed is larger than the critical fan rotating speed, the fresh air pipeline can start to generate the condensation phenomenon. Therefore, in the fan rotating speed adjusting range from the minimum fan rotating speed to the critical fan rotating speed, the current fan rotating speed is adaptively adjusted, so that the permission of preventing the fresh air pipeline from condensation and ensuring the fresh air function of a user can be met.
In addition, for example, aiming at the condition that the current fan rotating speed needs to be adjusted, the current fan rotating speed of the fresh air device can be adjusted at the maximum adjustable speed of the fan. For example, when the critical fan speed is greater than the minimum fan speed of the fan and is less than or equal to the current fan speed, the fan speed of the fan is adjusted from the current fan speed to the critical fan speed at the maximum adjustable speed of the fan.
FIG. 9 is a flowchart illustrating a method of controlling an air conditioner to adjust a current fan speed according to an exemplary embodiment.
For example, as shown in fig. 9, when it is determined that the fresh air device is started based on the triggering of the fresh air function, or when it is monitored that a temperature difference value between the current outdoor environment temperature and the current indoor environment temperature exceeds a preset threshold value in the running process of the fresh air device, the adjustment mode of the fresh air device for the fan rotation speed and the temperature range where the outdoor environment temperature is located may be determined.
Further, the critical fan rotating speed matched with the current environment parameter of the air conditioner can be determined under the condition that the fresh air device is set to automatically adjust the fan rotating speed and the current outdoor environment temperature is in the preset temperature range. For example, the ambient temperature and the ambient relative humidity may be obtained, and the dew point temperature and the absolute moisture content of the air may be determined based on the ambient temperature and the ambient relative humidity, and the critical fan speed may be determined based on the ambient temperature, the dew point temperature, and the absolute moisture content of the air. The manner in which the critical fan speed is determined by the ambient temperature, the dew point temperature, and the absolute moisture content of the air is described in the above embodiments, and reference may be made to any of the above embodiments for relevant matters.
Based on this, can adjust the current fan rotational speed of new trend device through critical fan rotational speed. For example, the blower may be turned off in the event that the threshold blower speed is less than or equal to the minimum blower speed of the blower. The fan speed of the fan can be adjusted from the current fan speed to the critical fan speed under the condition that the critical fan speed is larger than the minimum fan speed of the fan and smaller than or equal to the current fan speed. And the current fan rotating speed can be kept when the critical fan rotating speed is larger than the current fan rotating speed, or the current fan rotating speed is regulated to be the critical fan rotating speed, so that the problem of condensation of the fresh air pipeline is prevented or improved.
