Abstract: Among the APF weights of inverter air conditioners, low-temperature intermediate refrigeration accounts for the highest proportion which is the focus of inverter development. In the process of low-temperature intermediate refrigeration operation, the operation of the inverter compressor is greatly affected by the driving parameters. So how to optimize the driving parameters and make the compressor operation more reasonable is the focus of research. Focuses on the impact of the compressor current compensation value change on the performance of the whole machine, and analyzes its improvement effects through specific cases.

Key words: APF weight, Low temperature intermediate refrigeration, Current compensation value
