Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent 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 only a subset of the embodiments of the present disclosure, and not all embodiments. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. Embodiments of the present disclosure are described in detail below with reference to the accompanying 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 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 operating. In order to prevent the user in the closed place from feeling bored, the air conditioner can take fresh air from the outside to convey the fresh air to the inside. For example, the fresh air function of the air conditioner is started, and outdoor air is extracted by a fan of the fresh air device so as to be conveyed to the indoor space through a fresh air pipeline. In the process that the air conditioner executes the fresh air function through the fresh air device, because indoor and outdoor environmental parameters are unequal, condensation phenomenon usually occurs inside or outside a fresh air pipeline. For example, when the outdoor temperature is lower than the indoor temperature and the indoor air humidity is high, condensation is likely 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, condensation is likely to occur inside the fresh air pipeline. In the related art, if condensation occurs in a fresh air pipeline, problems such as air conditioner liquid leakage or short circuit of air conditioning equipment may occur, thereby causing damage to an air conditioner.
In the correlation technique, ambient temperature and ambient humidity can be monitored to the fan of new trend device is closed when confirming that current ambient temperature and current ambient humidity have the condensation risk. Although the problem of condensation of a fresh air pipeline can be solved by closing the fan in the related art, the method cannot enable a user to continue to use the fresh air function of the air conditioner, and user experience is poor.
The disclosure provides an air conditioner control method, which can determine the critical fan rotating speed matched with the current environmental parameters through the current environmental parameters 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 higher than the critical fan rotating speed under the current environmental parameters, condensation occurs on a fresh air pipeline in the fresh air device. Furthermore, the current fan rotating speed of the fresh air device can be adjusted through the critical fan rotating speed. Because the method adjusts the current fan rotating speed through the critical fan rotating speed instead of directly closing the fan in a 'cutting' mode, the condensation problem of a fresh air pipeline can be improved while the use of a 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 an air conditioner control method according to an exemplary embodiment, as shown in fig. 1, including the following steps.
In step S11, the current environmental parameters of the air conditioner are determined.
In the embodiment of the present disclosure, the current environmental parameter of the air conditioner may be understood as an environmental parameter of an environment where the air conditioner is currently located.
In step S12, a threshold fan speed that matches the current environmental parameter is determined.
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 higher than the critical fan rotating speed under the current environmental parameters, condensation occurs on a fresh air pipeline in the fresh air device. For example, if the fan of the fresh air device operates at a rotational speed greater than the critical fan speed under the current environmental parameters, condensation may occur in the fresh air pipeline 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.
The air conditioner control method provided by the embodiment of the disclosure can adjust the current fan rotating speed of the fresh air device through the critical fan rotating speed, and the method can dynamically adjust the fan rotating speed by taking the critical fan rotating speed as a reference. Furthermore, under the condition that the current environmental parameters are determined, the fresh air function can be executed at the adjusted rotating speed of the fan, and the use experience of a user is improved.
In the disclosed embodiment, the current environmental parameter may include, for example, a current ambient temperature and a current ambient relative humidity. For example, the dew point temperature and the absolute moisture content of the air may be determined according to the current ambient temperature and the current ambient relative humidity, and then the critical fan speed may be determined according to the ambient temperature, the dew point temperature, and the absolute moisture content of the air.
Fig. 2 is a flowchart illustrating another air conditioner control method according to an exemplary embodiment, and as shown in fig. 2, steps S21 and S24 in the embodiment of the present disclosure are similar to steps S11 and S13 in fig. 1, and are not described herein again.
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 environmental parameters can be obtained through the current environmental temperature, the dew point temperature and the absolute moisture content of air, and then the current fan rotating speed is adjusted by taking the critical fan rotating speed as a reference value, so that the problem of condensation of a fresh air pipeline can be solved while the normal execution of a fresh air function is ensured.
By way of example, may be

By determining the dew point temperature (exemplified by T_d represents). Wherein, a and b are preset constants for adjusting the value range of the dew point temperature, and lambda is used for representing the dew point temperature and the environment phaseIntermediate to the indirect relationship between humidity and ambient temperature. By way of example, may be

Determines the intermediate quantity lambda. Where T represents ambient temperature and U represents ambient relative humidity. In addition, the value range of the environment relative humidity is 0-100, so that the ratio of the environment relative humidity to 100 can approximately represent the current environment humidity state of the air-conditioning 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 also be set to other values according to actual requirements, and the set value of the preset constant is not specifically limited in this disclosure.
By way of example, may be
Figure BDA0003495275820000073
In a manner such that the absolute moisture content of the air is determined (an example is indicated by d). Where Pw represents the ambient water vapor partial pressure. In one embodiment, the partial pressure Pw of the ambient water vapor may be determined by the ambient temperature of the current environment of the air conditioner and the ambient relative humidity of the current environment of the air conditioner. For example, Pw ═ can be passed (0.0808T)3-1.0435T2+91.38T +309.45) × U, the ambient water vapour partial pressure Pw is determined. Where T represents ambient temperature and U represents 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 may be detected by corresponding detection elements provided 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) provided to the air conditioner. For another example, the ambient 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 ambient relative humidity sent by the server can be received by means of subscribing to the server. In one embodiment, an environmental parameter subscription request may be initiated to a station, such as a weather station, which may provide environmental parameter monitoring services, and the environmental parameters sent by the weather station may be periodically received after the subscription is successful. For example, the air conditioner may initiate a subscription request to a weather station and periodically receive the outdoor ambient temperature and/or outdoor ambient relative humidity sent by the weather station. Of course, the environmental parameter may also be obtained in other manners, which is not specifically limited by the present disclosure.

In step S41, a difference between the dew point temperature and the ambient temperature is determined, and the first parameter is determined based on the difference and a preset dew point difference.
The dew point difference is a temperature difference between a preset ambient temperature and a preset ambient dew point temperature, and may also 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 environment temperature and the environment dew point temperature is larger than the preset dew temperature difference, the condensation phenomenon of the fresh air pipeline may occur.

Wherein d represents the absolute moisture content of the air, d _ set represents the preset airGas absolute moisture content compensation parameter. Further, the adjustment parameter may be obtained by using the first parameter and the second parameter. For example, the first quantity (exemplified by

For example, if T _ d-T-m < 0, then r _ cal ═ rmaxIf T _ d-T-m is greater than or equal to 0, then r _ cal < rmax.

In the embodiment of the present disclosure, when the air conditioner performs the fresh air function through the fresh air device, the current environment of the air conditioner includes 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 moisture content of the air may include an indoor air absolute moisture content and an outdoor air absolute moisture content. And the condensation phenomenon of the fresh air pipeline is divided into fresh air pipeline external condensation and fresh air pipeline internal condensation. Therefore, for example, the currently possible condensation type can be determined according to the temperature comparison result between the outdoor environment temperature and the indoor environment temperature, and then the critical fresh air rotating speed can be obtained by matching the environmental parameters of the condensation type.
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, in the case where the outdoor ambient temperature is higher than the indoor ambient temperature, the critical fan rotation speed may be determined by the indoor dew point temperature, the outdoor ambient temperature, and the absolute moisture content of the indoor air.
Fig. 5 is a flowchart illustrating another air conditioner control method according to an exemplary embodiment, and as shown in fig. 5, steps S51, S52, and S54 in the embodiment of the present disclosure are similar to steps S21, S22, and S24 in fig. 2, and are not repeated herein.
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, the temperature may be adjusted by
Figure BDA0003495275820000101
In the manner of (a) or (b),a critical fan speed (e.g., denoted r cal) 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. Further, a represents an external condensation 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 indoor air absolute moisture content.
For example, if the outdoor ambient temperature is less than or equal to the indoor ambient temperature, the temperature may be adjusted by
Figure BDA0003495275820000102
In this manner, a critical fan speed (e.g., denoted as r _ cal) is determined. Where T _ d _ in represents an indoor dew point temperature, T _ out represents an outdoor ambient temperature, and d _ in represents an indoor air absolute moisture content. Furthermore, b represents an external condensation compensation parameter, which may be set to 7.5, for example.
In the above embodiment, for the fresh air pipeline, since the condensation outside the pipeline is compared with the condensation inside the pipeline, the temperature compensation parameters required when calculating the critical fan rotation speed are usually different. Therefore, by setting the external condensation compensation parameter (for example, indicated by b) for external condensation and the internal condensation compensation parameter (for example, indicated by a) for internal condensation, the accuracy of the calculated result value of the critical fan rotation speed can be ensured, thereby improving the adjustment accuracy for the fan rotation speed.
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 rotational speed of the fan.
In one embodiment, the fan speed adjustment mode in which the fresh air device is set may be detected, and the critical fan speed is determined under the condition that it is determined that the fresh air device is set to automatically adjust the fan speed, so as to adjust the current fan speed by the critical fan speed.
In another embodiment, the outdoor environment temperature may be detected, and when the outdoor environment temperature is within the preset temperature range, the critical fan speed is determined, and the current fan speed is adjusted by the critical fan speed.
Fig. 6 is a flowchart illustrating another air conditioner control method according to an exemplary embodiment, and as shown in fig. 6, steps S61 and S63 of the embodiment of the present disclosure are similar to steps S11 and S13 of fig. 1, and are not described herein again.
In step S62, in the case where it is determined that the fresh air device is set to automatically adjust the fan speed and the current outdoor environment temperature is within the preset temperature range, a critical fan speed matching the current environment parameter is determined.
The preset temperature range may be determined by a variation range of the indoor ambient temperature.
For example, in the case where the variation range of the indoor ambient temperature is determined, the minimum value of the indoor ambient temperature within the variation range may be determined, and the maximum value of the indoor ambient temperature within the variation range may be determined. Further, the outdoor environment temperature which meets the requirement of improving the condensation phenomenon in a mode of adjusting the rotating speed of the fan is determined respectively according to the minimum value and the maximum value of the indoor environment temperature, so that the maximum value and the minimum value of a preset temperature range are obtained, and the preset temperature range is further obtained.
Through 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 and whether the current outdoor environment temperature is within the preset temperature range can be judged in advance. Based on this, can realize only confirming that the new trend device is set up to automatically regulated fan rotational speed, and under the current outdoor ambient temperature was in the condition of predetermineeing temperature range, carry out follow-up flow, can reduce the invalid regulation to the fan rotational speed, when reducing the consumption, laminating in-service use demand.
In addition, in the embodiment of the disclosure, the current rotating speed of the fan can be adjusted only for a specific scene in which the condensation phenomenon needs to be improved in a manner of adjusting the rotating speed of the fan. For example, the current fan speed may be adjusted if it is determined that the fresh air device is activated based on the fresh air function trigger. For another example, in the operation process of the fresh air device, the current rotation speed of the fan may be adjusted when the temperature difference change value between the current outdoor environment temperature and the current indoor environment temperature is monitored to exceed the preset threshold value.
Fig. 7 is a flowchart illustrating another air conditioner control method according to an exemplary embodiment, and as shown in fig. 7, steps S71 and S73 of the embodiment of the present disclosure are similar to steps S11 and S13 of fig. 1, and are not described herein again.
In step S72, when it is determined that the fresh air device is triggered to start based on the fresh air function or when the temperature difference change 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 rotation 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 aiming at a specific scene that 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 slightly change, the method does not calculate the critical fan rotating speed again, and adjusts the current fan rotating speed, so that 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, in the case of determining the critical fan speed matching the current environmental parameter, the current fan speed of the fresh air device may be adjusted as follows.
Fig. 8 is a flowchart illustrating another air conditioner control method according to an exemplary embodiment, and as shown in fig. 8, steps S81 and S82 of the embodiment of the present disclosure are similar to steps S11 and S12 of fig. 1, and are not repeated herein.
In step S83a, the fan is turned off if the threshold fan speed is less than or equal to the minimum fan speed of the fan.
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 threshold 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 actual requirements.
In the embodiment of the disclosure, under the condition that the critical fan rotation speed is greater than the minimum fan rotation speed, the current fan rotation speed can be adaptively adjusted within the fan rotation speed adjustment range from the minimum fan rotation speed to the critical fan rotation speed. Because only aiming at the condition that the current fan rotating speed is greater than the critical fan rotating speed, the condensation phenomenon can begin to occur on the fresh air pipeline. Therefore, the current fan rotating speed is adaptively adjusted within the fan rotating speed adjusting range from the minimum fan rotating speed to the critical fan rotating speed, so that the permission of preventing condensation of a fresh air pipeline and ensuring the use of a fresh air function by a user can be met.
In addition, for the case that the current fan rotation speed needs to be adjusted, the current fan rotation speed of the fresh air device can be adjusted at the maximum adjustable speed of the fan. For example, the fan speed of the fan can be adjusted from the current fan speed to the critical fan speed at the maximum adjustable speed of the fan under the condition that the critical fan speed is greater than the minimum fan speed of the fan and less than or equal to the current fan speed.
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, under the condition that it is determined that the fresh air device is triggered and started based on the fresh air function, or in the operation process of the fresh air device, the temperature difference change value between the current outdoor environment temperature and the current indoor environment temperature is monitored to exceed the preset threshold, 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 speed matching the current environmental parameters of the air conditioner can be determined when it is determined that the fresh air device is set to automatically adjust the fan speed and the current outdoor environmental temperature is within the preset temperature range. For example, the ambient temperature and the ambient relative humidity may be obtained, the dew point temperature and the absolute moisture content of the air may be determined according to the ambient temperature and the ambient relative humidity, and the critical fan speed may be determined according to the ambient temperature, the dew point temperature and the absolute moisture content of the air. The manner of determining the critical fan speed through the ambient temperature, the dew point temperature, and the absolute moisture content of the air has been described in the above embodiments, and reference may be made to any of the above embodiments for relevant contents.
Based on this, can adjust the current fan rotational speed of new trend device through critical fan rotational speed. For example, the fan may be turned off if the threshold fan speed is less than or equal to the minimum fan speed of the fan. The fan rotating speed of the fan can be adjusted from the current fan rotating speed to the critical fan rotating speed under the condition that the critical fan rotating speed is greater than the minimum fan rotating speed of the fan and less than or equal to the current fan rotating speed. And when the critical fan rotating speed is greater than the current fan rotating speed, the current fan rotating speed is kept, or the current fan rotating speed is adjusted to be the critical fan rotating speed, so that the condensation problem of the fresh air pipeline is prevented or improved.
