How does a refrigerator compressor work?

Nowadays, household refrigerators use hermetic piston compressor. The working principle is mainly through the piston in the cylinder constantly reciprocating movement to complete. Piston in the cylinder reciprocating the whole process is divided into suction, compression and exhaust three processes, known as a working process. We are in order to describe the convenience of single-stage single-acting and double-acting piston compressor a cylinder were simplified. Piston compressor compressed gas double-acting type because both ends of the cylinder are equipped with inlet and exhaust valves, therefore, the piston compressor compressed gas in the same time, regardless of the piston to the right or to the left movement, can be completed in front of the compression and exhaust process, in the back of the completion of the suction process. That is, the crankshaft rotates one week to complete the two processes. As the piston compressor gas compression piston in the cylinder constantly reciprocating movement, the cylinder will cycle suction, compression and exhaust. The first reciprocation of the piston is known as a working cycle, that is, a working process, the piston reciprocates every time through the distance known as the piston compressor compressed gas stroke. The process of gas compression, mainly through the piston in the cylinder constantly reciprocating motion to complete. Piston reciprocating in the cylinder once the whole process is divided into suction, compression and exhaust three processes, known as a work process. We are in order to describe the convenience of single-stage single-acting and double-acting piston compressor a cylinder were simplified. Piston compressor compressed gas double-acting type because both ends of the cylinder are equipped with inlet and exhaust valves, therefore, the piston compressor compressed gas in the same time, regardless of the piston to the right or to the left movement, can be completed in front of the compression and exhaust process, in the back of the completion of the suction process. That is, the crankshaft rotates one week to complete the two processes. As the piston compressor gas compression piston in the cylinder constantly reciprocating movement, the cylinder will cycle suction, compression and exhaust. The first reciprocation of the piston is called a working cycle, that is, a working process, the piston reciprocates once every distance known as the piston compressor compressed gas stroke.
