Problems solved by technology
However, under the rated cooling conditions, the system requires the compressor to have low power consumption and low compression ratio to improve the energy efficiency ratio, but the high pressure ratio generated by the two-stage compression makes the power consumption of the compressor high, which is not good for the rated cooling; on the other hand, the two-stage compression The suction of the second cylinder of the stage compressor is provided by the exhaust of the first cylinder, and the continuity of the suction (inhalation at 360 degrees) corresponds to the intermittence of the exhaust (only about 120 degrees of exhaust), resulting in the second cylinder's suction Unsaturated, low volumetric efficiency, high power consumption and low energy efficiency ratio in the air conditioning system

Description
【Technical field】 [0001] The invention relates to a compressor working under various working conditions, in particular to a two-stage double-cylinder compressor with high refrigeration performance. 【Background technique】 [0002] The two-stage compressor increases the compression ratio through two compressions, which is very suitable for low-temperature heating of heat pump water heaters under high-pressure ratio conditions, and is also suitable for high-temperature refrigeration of air conditioners under high-pressure ratio conditions. However, under the rated cooling conditions, the system requires the compressor to have low power consumption and low compression ratio to improve the energy efficiency ratio, but the high pressure ratio generated by the two-stage compression makes the power consumption of the compressor high, which is not good for the rated cooling; on the other hand, the two-stage compression The suction of the second cylinder of the stage compressor is pro...
