Abstract

The invention relates to a miniature moving-magnetic series-connection two-stage linear compressor which comprises a low-pressure-stage compressor, a middle kit and a high-pressure-stage compressor. The high-pressure-stage compressor and the low-pressure-stage compressor are oppositely arranged, are the same in structure and each comprise a shell, an overall rack, a linear motor and a rotor part. An air inlet is formed in the middle kit, saturated refrigerant steam coming out of a middle cooler enters a cavity of the middle kit through the air inlet, is mixed with refrigerant gas exhausted by the low-pressure-stage compressor in a compressed mode, and then enters an air suction cavity of the high-pressure-stage compressor through a round air suction hole in the overall rack of the high-pressure-stage compressor. When a high-pressure-stage compressor piston moves towards the compression cavity side, refrigerant gas is compressed, and two-stage compression is achieved. The low-pressure-stage linear compressor and the high-pressure-stage linear compressor are connected in series for operation, the pressure ratio and efficiency are improved, the exhaust temperature is reduced, and vibration and noise of the compressor are reduced.

Description

technical field

[0001] The invention relates to a compressor, in particular to a miniature moving magnet series two-stage linear compressor. Background technique

[0002] The compression refrigeration cycle is one of the main methods of refrigeration, and it is widely used in refrigerators and air-conditioning systems, so the compressor is compared to the heart of the air-conditioning system. The air conditioner compressor consumes a lot of electricity when it works. Compared with traditional reciprocating piston compressors, linear compressors have the characteristics of compact structure, small size, low energy consumption and high efficiency. Their applications have gradually shifted from aerospace and other military fields to civilian refrigeration equipment such as refrigerators and air conditioners. After the 1990s, foreign countries began to develop linear compressors for household refrigerators. Sunpower in the United States has the technology to develop linear comp...
