[0065] refer to figure 2 , the present invention provides a first embodiment of a control method for compressor self-protection, the control method for compressor self-protection includes the following steps:
[0066] Step S10, detecting the operating current value of the compressor during operation;
[0067] The operating current value is the actual current value of the compressor during operation. In this embodiment, the operating current value of the compressor during operation can be directly detected by a current detection device, or can be detected by a voltage detection device , calculating the operating current value during the operation of the compressor through the detected voltage value.
[0068] Step S20, determining the current protection threshold of the compressor according to the current reference value of the compressor and the allowable current deviation value of the compressor;
[0069] The current reference value of the compressor is the reference curren...

The invention discloses a compressor self-protection control method, which detects the operating current value of the compressor during operation; determines the compressor current value according to the current reference value of the compressor and the allowed current deviation value of the compressor. A current protection threshold; judging whether the operating current value exceeds the current protection threshold; when the operating current value exceeds the current protection threshold, stop running the compressor. The invention also discloses a compressor self-protection control device, an air conditioner and a storage medium. In the present invention, the current protection threshold of the compressor is determined by the current reference value of the compressor and the allowable current deviation value of the compressor, and then it is judged whether the operating current value of the compressor exceeds the current protection threshold, and when the operating current value exceeds the current protection threshold In this way, when a partial fault occurs, the abnormality can be fed back accurately and timely, and the reliability of the operation of the whole machine can be improved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a compressor self-protection control method and device, an air conditioner and a storage medium. Background technique [0002] As a device for improving the indoor environment, air-conditioning is more and more favored by people, and air-conditioning has generally entered families now. Since the air conditioner has functions such as temperature adjustment, defrosting control, humidity adjustment, air flow speed adjustment and air cleanliness adjustment, the structure is complex and the power is large during operation. When the air conditioner is used for a long time or works with high power for a long time, some failures will inevitably occur If the protection is not timely, the air conditioner compressor will be demagnetized and burned out. [0003] In order to protect the air conditioner compressor, the air conditioner in the prior art sets a series of pressure protec...
