Problems solved by technology
[0002] The performance of ordinary compressors drops significantly when heating at low temperatures, so auxiliary electric heating is needed to meet the heating capacity requirements of the system, which will increase power consumption; most of the existing rotary dual-rotor compressors use the upper cylinder to exhaust upwards , The lower cylinder exhausts downward, and then guides the discharged gas upward through the flow hole, and this exhaust structure increases the exhaust resistance and reduces the performance of the compressor
[0003] Due to the limitation of the structure of the existing rotary double-rotor compressor, the two-stage compression used for the existing R22 and R410A refrigerants can be divided into two-machine two-stage compression system and single-machine two-stage compressor system, and the two-machine two-stage compression system is too large to be applied In small-displacement air conditioners, the intercooling effect of the single-unit two-stage compressor is very poor, resulting in a low energy efficiency level, which further affects the scope of application of the rotary double-rotor compressor
