Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Referring to fig. 1, an embodiment of the present invention provides a method for controlling heating and defrosting of an air conditioner, which is applied to an air conditioner, and optionally the air conditioner is a variable frequency air conditioner. The air conditioner includes an outdoor unit having an outdoor fan, which may be selected as a direct current fan. When the air conditioner heats and runs in winter, the frosting process is a slower process, so that the current value of the outdoor fan can be detected in real time for a longer time, and the current value of the outdoor fan can be rapidly increased under the condition that the outdoor fan runs at the same wind speed due to the fact that the load of the whole outdoor fan is increased after the outdoor fan frosts, the frosting condition of the unit can be accurately detected through detecting the change condition of the current value of the outdoor fan, and therefore the frosting condition can be judged by utilizing the current value of the outdoor fan. The air conditioner heating defrosting control method provided by the embodiment of the invention can judge whether the unit frosts or not by judging the current value of the outdoor fan, so that whether defrosting control is performed is determined, the defrosting process is effectively executed, the situation of frequently entering defrosting is effectively improved, and the comfort of a user is greatly improved.
The method for controlling the heating defrosting of the air conditioner comprises the following steps:
Step S100, acquiring an initial gear, an initial current value and a first preset reference fan current value corresponding to the initial gear of the operation of the outdoor fan in a first preset time of heating and starting of the air conditioner.
In step S100, the air conditioner may be considered as an initial state within a first preset time period after heating and starting up, that is, within a time period immediately after starting up. The first preset time t1 may be 3min as an example. In addition, the outdoor fan is provided with a plurality of different gears, the outdoor fan can operate at different set rotating speeds, and the initial gear is the gear of the operation of the outdoor fan in the first preset time. In this embodiment, the outdoor fan is set to 5 wind speeds.
In addition, the first preset reference fan current value characterizes a reference fan current value of the outdoor fan running in an initial gear and without frosting. The first preset reference fan current value is denoted by I Gear current initiation . The outdoor fan is operated under the conditions of different wind ranges and no frosting to obtain a plurality of reference fan current values, wherein the reference fan current values are increased along with the rising of the wind range of the outdoor fan. The reference fan current value is denoted by I Datum , and is an outdoor fan current value preset in advance, and is used as a reference for judgment, and the reference fan current values under different wind ranges are different. The reference fan current value is based on the current value tested under the outdoor frostless condition of the experiment, and the reference fan current value corresponding to each gear is preset into a program after the experimental result is obtained. It should be noted that, the reference fan current value may also be different according to different fan types, and the test and the setting may be performed according to actual needs. The first preset reference fan current value is one of a plurality of reference fan current values, and is the reference fan current value corresponding to the initial gear.
As an example, taking the outdoor fan as 5 wind speeds as an example, the corresponding reference fan current values are shown in the following table:
| Wind shield | Outdoor fan rotating speed | Reference fan current value I Datum |
| 0 | 0 | I Datum 0＝0mA |
| 1 | 300 Rpm | I Datum 1＝210mA |
| 2 | 400 Rpm | I Datum 2＝330mA |
| 3 | 600 Rpm | I Datum 3＝540mA |
| 4 | 800 Rpm | I Datum 4＝680mA |
| 5 | 900 Rpm | I Datum 5＝850mA |
As can be seen, the gear of the outdoor fan is increased, and the rotation speed of the outdoor fan is increased, so that the reference fan current value is correspondingly increased. As an example, the initial gear is wind gear 3, the first preset reference wind current value I Gear current initiation ＝I Datum 3 =540 mA.
The initial current value is the current value when the outdoor fan operates at the initial gear within the first preset time of heating and starting the air conditioner. Wherein the initial current value is denoted by Ifan Initial initiation .
Referring to fig. 2, in order to improve the accuracy of obtaining the initial current value, in this embodiment, the step S100 may include the following sub-steps S110 and S120.
And step S110, acquiring the interval time current value of the primary outdoor fan every interval preset time period in the first preset time of heating and starting the air conditioner.
In the substep S110, the first preset time is equally divided into a plurality of preset time periods, and an interval time current value is obtained once every interval of one preset time period, where the interval time current value is denoted by Ifan n, n is a positive integer, and the value is correspondingly taken according to the actual requirement. Thus, the plurality of interval current values are Ifan, ifan2, …, ifan n in sequence, each interval current value representing the current value at the end of the nth preset time period. As an example, the first preset time is exemplified by 3min, and the preset time period is exemplified by 30s, n=6. Acquiring an interval time current value once every 30s, wherein Ifan1 is an outdoor fan current value at the moment of heating starting up for 30 s; ifan2 is the outdoor fan current value at 60s of heating start-up; ifan3 is the outdoor fan current value at 90s of heating start-up; ifan4 is the outdoor fan current value at the heating start-up time of 120 s; ifan5 is the outdoor fan current value at the heating start-up time of 150 s; ifan6 is the outdoor fan current value at 180s of heating start-up, thereby obtaining 6 interval time current values.
Substep S120, calculating an initial current value equal to an average of the plurality of interval time current values.
In sub-step S120, an average value of the plurality of interval time current values is calculated to obtain an initial current value, i.e., initial current value Ifan Initial initiation = (Ifan 1+ Ifan2+ … + Ifan n)/n, where n is a positive integer. As an example, the first preset time is exemplified by 3min, and the preset time period is exemplified by 30s, n=6. Thus, the initial current value Ifan Initial initiation = (Ifan 1+ Ifan2+ Ifan3+ Ifan4+ Ifan5+ Ifan 6)/6.
The initial current value is obtained by calculating the average value of the current values at a plurality of intervals, so that the influence of current fluctuation on the initial current value can be reduced, and the accuracy of the initial current value is improved.
Referring to fig. 1, in step S200, after the air conditioner is operated for a second preset time, a current value of the outdoor fan, a current gear and a second preset reference fan current value corresponding to the current gear are obtained in real time. Wherein the second preset time is greater than the first preset time.
In step S200, after the air conditioner is heated and started to operate for a second preset time t2, a current value and a current gear of the outdoor fan are obtained in real time, and a second preset reference fan current value corresponding to the current gear is obtained. As an example, the second preset time may be selected to be 30min, the current value is denoted by Ifan currently, the method is that , the current gear is denoted by S Defrosting agent , and the second preset reference fan current value is denoted by I gear electric current defrosting device . The second preset reference fan current value is one of a plurality of reference fan current values, and is the reference fan current value corresponding to the current gear. In this embodiment, the outdoor fan is still used for 5-gear wind speed, and if the current gear is the wind gear 5, the second preset reference fan current value I gear electric current defrosting device ＝I Datum 5 =850 mA.
And step S300, converting the initial current value into a defrosting judgment reference current value corresponding to the current gear according to the initial gear and the current gear.
In step S300, the defrosting determination reference current value is a current value for comparing with the current value in the subsequent step to determine whether to perform defrosting, and represents a theoretical current value of the outdoor fan operating in the current gear after the second preset time elapses. It should be noted that, when the outdoor fan is just started, the initial current value of the outdoor fan is recorded in the first preset time, but in the running process, the gear of the outdoor fan is likely to change according to different loads, when the gear of the outdoor fan changes, the initial current value Ifan Initial initiation recorded when the outdoor fan is started cannot reflect the current value of the current gear, so that the defrosting judgment reference current value is obtained through conversion to reflect the theoretical current value of the current gear.
In this embodiment, in order to more accurately reflect the changes of the frosting-free condition and the different gear positions, the first preset reference fan current value and the second preset reference fan current value are further introduced to serve as calculation references of the frosting judgment reference current value, so that accuracy of the frosting judgment is improved. Therefore, in step S300, the defrosting determination reference current value may be calculated according to the first preset reference wind current value, the second preset reference wind current value, and the initial current value.
Further, in this embodiment, the defrosting judgment reference current value may be obtained by calculation according to the following calculation formula:
Ifan Defrosting standard ＝(Ifan Initial initiation *I gear electric current defrosting device )/I Gear current initiation ；
Wherein Ifan Defrosting standard denotes a defrosting judgment reference current value, ifan Initial initiation denotes an initial current value, I gear electric current defrosting device denotes a second preset reference fan current value, and I Gear current initiation denotes a first preset reference fan current value.
It should be noted that, by introducing the first preset reference current value and the second preset reference current value of the air conditioner, the situation that the outdoor fan operates in the frost-free state is considered in conversion, so that the frost-free judging reference current value can represent the current value of the outdoor fan in the current gear and in the frost-free state after the air conditioner operates for a second preset time, and thus the current value can be used as the reference current value of the frost judgment in the subsequent step, for example, the initial gear is the wind gear 3, the current gear is the wind gear 5, and the frost-free judging reference current value in the wind gear 5 and in the frost-free state can be calculated by the above calculation formula. And through conversion, the defrosting judgment in the subsequent step can be unified to the same outdoor fan gear for judgment, so that the accuracy of judgment is improved.
Step S400, judging whether the current value and the defrosting judgment reference current value meet defrosting conditions.
In step S400, the defrosting condition is a preset condition for comparison between the present current value and the defrosting judgment reference current value.
Referring to fig. 3, in this embodiment, in order to improve accuracy of defrosting determination, suitable defrosting conditions may be designed, and alternatively, the defrosting conditions may be that a ratio of the current value to a reference current value of defrosting determination is greater than a preset change rate of the outdoor fan current and lasts for a third preset time. Thus, step S400 may include the following substep S410.
Substep S410, determining whether the ratio of the current value to the defrosting determination reference current value is greater than the preset change rate of the outdoor fan current and lasts for a third preset time.
In sub-step S410, the preset change rate of the outdoor fan current is a preset change rate, which may be denoted by a, and may be set accordingly according to actual needs. The third preset time is a preset duration time, which can be represented by t3 and can be set correspondingly according to actual needs. In sub-step S410, it is determined whether Ifan currently, the method is that /Ifan Defrosting standard > A is satisfied for t3. In the embodiment, the preset change rate of the current of the outdoor fan can be selected to be 140-160%, and further selected to be 150%; the value range of the third preset time is 8-12 s, and further 10s is selected.
Referring to fig. 1, in step S500, if the current value and the defrosting determination reference current value satisfy the defrosting condition, the air conditioner is controlled to perform defrosting.
In step S500, if the defrosting condition is satisfied, it is considered that the outdoor unit has frosted to a certain extent and defrosting is required, and the air conditioner is controlled to perform defrosting.
If the defrosting condition is not satisfied, it may be considered that the outdoor unit does not have frosting or the frosting does not reach the preset degree, and the air conditioner is not required to be controlled to perform defrosting, and the method returns to step S200, continues to obtain the current value of the outdoor fan, the current gear and the second preset reference fan current value corresponding to the current gear in real time, continues to execute steps S300-S400, and then performs corresponding control according to the determination result of step S400.
Referring to fig. 3, further, in the present embodiment, step S500 may include sub-step S510.
And S510, if the ratio of the current value to the defrosting judgment reference current value is larger than the preset change rate of the outdoor fan current and lasts for a third preset time, controlling the air conditioner to defrost.
In substep S510, if Ifan currently, the method is that /Ifan Defrosting standard > a is satisfied and t3 is continued, the entering defrosting condition is satisfied, and the air conditioner is controlled to defrost. It should be noted that, the current value is compared with the reference current value for defrosting judgment, that is, the current value is compared with the current value of the outdoor fan in the current gear and in the frostless state, and the relationship between the current value and the preset change rate of the outdoor fan current is judged, so that whether the change generated by the current value of the outdoor fan in the current gear and in the frostless state meets the preset requirement or not compared with the change generated by the current value of the outdoor fan in the current gear and in the frostless state after the second preset time passes theoretically is determined, and in order to improve the judgment accuracy, whether the duration time meets the third preset time is judged again, so that whether the outdoor unit frosts to a certain extent or not can be reflected more truly, and defrosting is required.
Therefore, the air conditioner heating defrosting control method provided by the embodiment of the invention can reflect the frosting condition of the outdoor unit more truly through the current value of the outdoor fan, avoid the situation that the outdoor unit erroneously judges defrosting to defrost and frequent defrosting and indoor temperature reduction are caused, and further improve the heating effect. In addition, the change of the current value is generated by considering the gear change, and the comparison and judgment of the front current value and the rear current value can be carried out under the same gear through the conversion of the defrosting judgment reference current value, so that the change condition of the outdoor fan current value is reflected more truly, and the accuracy of defrosting judgment is improved.
