Abstract

The invention discloses a frequency limiting control method for compressor exhaust temperature, an air conditioner and a readable storage medium. During the process of increasing the frequency of the compressor, the frequency limiting frequency is dynamically adjusted according to the exhaust temperature. , the exhaust gas temperature reaches the first temperature threshold, and a new frequency limit frequency is generated. The new frequency limit frequency is smaller than the frequency limit frequency during this frequency increase, so as to prevent the compressor frequency from increasing again during the next frequency increase. Up to the frequency limit frequency of the last frequency increase, which will trigger the frequency reduction temperature threshold again, thereby reducing the frequent occurrence of frequency limit fluctuations caused by periodic fluctuations in exhaust temperature, reducing system fluctuations, and improving the reliability of air conditioning system operation.

Description

technical field [0001] The present invention relates to the technical field of compressors, in particular to a frequency-limiting control method for compressor discharge temperature, an air conditioner and a readable storage medium. Background technique [0002] When the air conditioner is running at high load or there is refrigerant leakage, the discharge temperature is usually relatively high. When the discharge temperature rises above a threshold, the frequency of the compressor will be reduced to suppress the rise of the discharge temperature or make it When the exhaust temperature is lower than a threshold value, the frequency limit will be released again, and the compressor frequency will increase again at this time. [0003] However, since the discharge temperature detects the temperature on the exhaust copper pipe, the detected temperature change is much slower and lags behind the adjustment of the system. The temperature may still drop, and when the frequency reach...
