Abstract: The inherent feature of fixed inner volume ratio of the scroll compressor causes large degradation of the compressor’s indicated efficiency when the inner compression ratio mismatches with the system compression ratio under the off-design condition. The inner compression ratio adjustment technology, such as refrigerant injection and refrigerant release, can enhance the seasonal efficiency of the compressor and the air conditioner. An inverter air conditioner with inner compression ratio adjustment is proposed in this paper. Through a seasonal simulation, a conclusion can be made: the implement of inner compression ratio adjustment can decrease the power consumption of the air conditioner 10%~25%.
