Problems solved by technology
[0004] However, in the existing air conditioner frequency control process, the continuous running time of the compressor at one or some fixed frequency points is fixed and cannot be changed according to different working conditions
Since the fixed continuous running time is generally a value determined under ideal and specific test conditions, in the actual use of the air conditioner, it is easy to have problems when the actual working conditions change, such as the continuous running time is too short As a result, the oil return is insufficient and the indoor temperature fluctuates greatly, or the rapid temperature adjustment effect is affected due to the long continuous operation time, which affects the performance of the air conditioner

Embodiment Construction
[0025] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] See figure 1 , which is a flow chart of an embodiment of the air conditioner frequency control method of the present invention, specifically, a flow chart of an embodiment of the control process for controlling the frequency increase of the compressor after the air conditioner is turned on.
[0027] Such as figure 1 As shown, in this embodiment, the control process of controlling the frequency increase of the compressor after the air conditioner is turned on includes the following steps:
[0028] Step 11: When the frequency of the compressor rises to the set frequency for continuous operation, obtain the difference between the real-time indoor ambient temperature and the target set temperature as the real-time temperature difference.
[0029] Wherein, the set frequency is a known and preset fixed fr...

The invention discloses an air conditioner frequency control method. The air conditioner frequency control method comprises a control process of controlling frequency rise of a compressor after opening of an air conditioner; and the control process of controlling frequency rise of the compressor comprises the following steps: when the frequency of the compressor rises to a set frequency needed to continuously operate, a difference value between a real-time indoor environment temperature and a target set temperature is obtained as a real-time temperature difference; a lasting time corresponding to the real-time temperature difference is determined according to a relation between known lasting time and the temperature difference as a real-time lasting time; the relation is a negative correlation relation; and the compressor is controlled to continuously operate by the real-time lasting time at the set frequency. The method controls the frequency of the compressor, and can improve the operation performance of the air conditioner.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioner control method, and more specifically relates to an air conditioner frequency control method. Background technique [0002] When the existing air conditioner is just started, in order to achieve rapid cooling or heating effects, the compressor is generally controlled to rapidly increase the frequency to run at a higher target frequency. When the compressor is running, the refrigerant in the compressor will be quickly discharged in large quantities and circulated in the pipeline system. If the frequency increase of the compressor is too fast, the refrigerant will not flow back into the compressor in time, and will not be able to lubricate and cool down, which will have a bad impact on the performance of the compressor. [0003] In order to avoid the above problems, most of the air conditioner control process will force the compressor to con...
