Abstract

The invention discloses a compressor exhaust gas temperature frequency limit control method, an air conditioner and a readable storage medium. In the compressor frequency rising process, the limited frequency is dynamically adjusted according to exhaust gas temperature; if the exhaust gas temperature reaches a first temperature threshold value in the current frequency rising process, new limited frequency is generated, the new limited frequency needs to be lower than the limited frequency of the current frequency rising, and thus the situation that the frequency of a compressor rises to the limited frequency of last frequency rising during next frequency rising, and consequently a frequency reducing temperature threshold value is triggered again is avoided; and therefore frequent limited frequency fluctuations caused by the cyclical fluctuation of the exhaust gas temperature are reduced, system fluctuations are reduced, and the reliability of air conditioning system operation is improved.

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...
