Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a block flow diagram illustrating a defrosting frequency adjusting method according to the present embodiment. The defrosting frequency adjusting method is applied to the air conditioner, achieves self-adaptive adjustment of the defrosting frequency of the air conditioner, ensures that defrosting is finished in a short time, and simultaneously avoids the problem of low abnormal voltage. The defrosting frequency adjusting method comprises the following steps:
and step S101, controlling the air conditioner to perform first defrosting after single startup at an initial frequency.
The first defrosting after each restart of the air conditioner is performed at an initial frequency. The initial frequency ranges from 50HZ to 150HZ, and 90HZ is preferred in this embodiment.
Further, the defrost frequency adjustment method may further include:
and step S102, acquiring a low-pressure value of the air conditioner in the current defrosting process.
In fact, step S102 may start from any defrosting process of the air conditioner throughout the operation. In this embodiment, step S102 starts with the first defrosting of the air conditioner, that is, when the air conditioner performs defrosting with the initial frequency as the defrosting frequency, the low-pressure value of the air conditioner in the process is obtained in real time.
Further, the defrost frequency adjustment method may further include:
and step S103, acquiring the defrosting time of the current defrosting process.
Similarly, step S103 may be started from any defrosting process of the air conditioner during the entire operation process, and corresponds to step S102. In this embodiment, step S103 starts with the first defrosting of the air conditioner, that is, when the air conditioner performs defrosting with the initial frequency as the defrosting frequency, the time duration used in the defrosting process is counted to obtain the defrosting time.
Further, the defrost frequency adjustment method may further include:
step S104, comparing the low-pressure value with a preset pressure value to obtain a first comparison result.
The low pressure value obtained in step S102 is compared with a preset pressure value, in this embodiment, the preset pressure value includes a first preset pressure value and a second preset pressure value, and the first preset pressure value is smaller than the second preset pressure value. The first predetermined pressure value is in the range of 0bar to 2bar, preferably 1bar in this embodiment. The second predetermined pressure value ranges from 3bar to 10bar, preferably 3bar in this embodiment.
Because the preset pressure value comprises a plurality of values, a plurality of comparison results can be obtained by comparing the low-pressure value with the plurality of values, namely, the first comparison result can represent various conditions.
Further, the defrost frequency adjustment method may further include:
step S105, comparing the defrosting time with the preset time to obtain a second comparison result.
The value range of the preset time is 8min to 12min, and 12min is preferred in this embodiment. And comparing the defrosting time with the preset time to obtain a second comparison result, wherein the second comparison result comprises three conditions: the defrosting time is less than 12min, the defrosting time is equal to 12min, and the defrosting time is greater than 12 min.
Further, the defrost frequency adjustment method may further include:
and S106, adjusting the defrosting frequency of the next defrosting of the air conditioner according to the first comparison result and the second comparison result.
And according to the low-pressure value condition and the defrosting time condition of the air conditioner in the current defrosting process represented by the first comparison result and the second comparison result, the low-pressure value condition and the defrosting time condition are used as defrosting frequency adjusting bases for next defrosting of the air conditioner, so that the defrosting frequency in the next defrosting process can be more accurate.
Referring to fig. 2, fig. 2 is a block diagram illustrating a sub-step flow of step S106, wherein step S106 includes:
and a substep S1061, adjusting the defrosting frequency in the current defrosting process to be smaller as the defrosting frequency for the next defrosting when the low-pressure value is less than or equal to the first preset pressure value and the defrosting time is less than or equal to the preset time.
When the first comparison result represents that the low-pressure value is smaller than 1bar of the first preset pressure value, or represents that the low-pressure value is equal to 1bar of the first preset pressure value, and the second comparison result represents that the defrosting time is smaller than 12min of the preset time, or represents that the defrosting time is equal to 12min of the preset time, the low pressure in the current defrosting process is extremely low, and the defrosting time is short enough, so that the current defrosting frequency is too high, and the defrosting frequency in the current defrosting process is reduced and then is used as the defrosting frequency of the next defrosting. Step S102 is to reduce the defrosting frequency 90HZ of the first defrosting process from the first defrosting of the air conditioner to be the second defrosting frequency of the air conditioner.
In this embodiment, the substep S1061 further includes: and reducing the defrosting frequency in the current defrosting process by a first regulating frequency to be used as the defrosting frequency of the next defrosting. Namely, under the condition that the low-pressure value is less than or equal to the first preset pressure value and the defrosting time is less than or equal to the preset time, the defrosting frequency in the current defrosting process is reduced by the first adjusting frequency to be used as the defrosting frequency of the next defrosting. In this embodiment, the first adjustment frequency is 5 HZ.
And a substep S1062 of increasing the defrosting frequency in the current defrosting process as the defrosting frequency for the next defrosting when the low-pressure value is greater than or equal to the second preset pressure value and the defrosting time is greater than the preset time.
When the first comparison result represents that the low-pressure value is greater than the second preset pressure value by 3bar, or represents that the low-pressure value is equal to the second preset pressure value by 3bar, and the second comparison result represents that the defrosting time is greater than the preset time by 12min, the current low-pressure value is higher, and the defrosting time is longer, so that the current defrosting frequency is too low, and the defrosting frequency in the current defrosting process is adjusted to be higher and then is used as the defrosting frequency of the next defrosting. Step S102 is to increase the defrosting frequency 90HZ of the first defrosting process from the first defrosting of the air conditioner to be the defrosting frequency of the second defrosting of the air conditioner.
In this embodiment, the substep S1062 further includes: and increasing the defrosting frequency in the current defrosting process by a second adjusting frequency to be used as the defrosting frequency of the next defrosting. Namely, under the condition that the low-pressure value is greater than or equal to the second preset pressure value and the defrosting time is greater than the preset time, the defrosting frequency in the current defrosting process is increased by the second adjusting frequency to be used as the defrosting frequency of the next defrosting. In this embodiment, the second adjustment frequency is also 5 HZ.
The defrost frequency adjustment method provided by the present invention is further illustrated by the following example:
heating and operating a certain multi-outdoor unit at the temperature of-10 ℃, defrosting the unit for the first time after starting the unit and operating for 50min, wherein the defrosting frequency is 90Hz, the defrosting time is 5min (less than the preset time of 15min), and when a low-pressure value of 1bar (equal to the first preset pressure value of 1bar) is detected in the defrosting process, defrosting is performed after heating for the second time for 50min, and the defrosting frequency is reduced to 85 Hz.
It can be seen that, in the defrosting frequency adjusting method provided by this embodiment, if the low pressure is extremely low during the defrosting process and the defrosting time is also short enough, the next defrosting frequency is properly decreased. If after the frequency is reduced, the defrosting low pressure is not low, then the next defrosting maintains the last frequency; if a higher low pressure condition occurs during defrost and the defrost time is longer, the next defrost frequency is increased appropriately. If after the up-conversion, the defrost time is not that long, the next defrost maintains the last frequency. Therefore, the air conditioner can be ensured to defrost at a more accurate defrosting frequency in addition to the first defrosting after starting.
Therefore, when the defrosting frequency adjusting method provided by the embodiment is applied to an air conditioner, the self-adaptive adjustment of the defrosting frequency of the air conditioner can be realized, the defrosting can be ensured to be completed in a short time, and meanwhile, the problem that the low voltage is abnormally low is avoided.
