Tips:

(1) Compression process: When the piston is in the lowest position I-I (called the lower stop point or lower dead point), the cylinder is filled with low-pressure refrigerant gas inhaled from the evaporator, and the suction process ends. The piston is driven by the crankshaft linkage
When the initial upward movement, the suction valve closes and the working volume of the cylinder gradually decreases. The pressure and temperature of the gases sealed in the cylinder are gradually increased due to the decrease of the volume, and when the piston moves upwards to positions II-II, the gas pressure in the cylinder rises slightly higher than the pressure in the exhaust cavity. The exhaust valve opens automatically and begins to exhaust. The process by which the refrigerant gas rises in the cylinder from the low pressure at the time of intake to the high pressure at the time of exhaust is called the compression process.
(2) Exhaust process: the piston continues to move upwards, the gas pressure in the cylinder is no longer raised, but continuously outputs to the exhaust cavity through the exhaust valve until the piston moves to the highest position III-III (called the upper stop point or upper dead point) When the exhaust process ends. The process of gas being output from the cylinder to the exhaust chamber is called the exhaust process.
(3) Expansion process: When the piston moves to the position of the upper stop point, due to the gap between the top of the piston and the valve plate, the volume formed by the gap is called the residual gap volume. At the end of the exhaust process, due to the presence of the residual gap, there is a certain amount of high-pressure gas in the cylinder residual volume. When the piston begins to move downwards, the exhaust valve closes. However, the low-pressure vapor in the intake cavity cannot enter the cylinder immediately, but first expands the high-pressure gas remaining in the cylinder due to the increase in volume. Cause the pressure to drop until the pressure in the cylinder drops slightly below the pressure in the suction chamber. The process of moving the piston position from III-III to IV-IV is called the expansion process.
(4) Suction process When the piston moves to the IV-IV position, the intake valve automatically opens. As the piston continues to move downwards, the low-pressure gas continues to enter the cylinder through the intake chamber and intake valve through the evaporator until the piston reaches the position of the lower stop point I-I. This process is called the inspiratory process.
After completing the suction process, the piston moves from the lower stop point to the upper stop point, restarting the compression process, and so on. The compressor goes through the four processes of compression, exhaust, expansion and suction, and sucks the low-pressing refrigerant gas in the evaporator to increase its pressure and discharge it into the condenser, completing the role of suction, compression and pumping of refrigerant.
In the compression process, if the gas contains liquid, due to the increase in temperature and pressure, the droplets evaporate rapidly, and the energy released makes the pressure of the cylinder increase instantaneously, and the resistance of the piston suddenly increases, as if it is hit hard. This is the phenomenon of "liquid strike". "Liquid Strike" can cause damage to the part. If too much liquid is inhaled, because the liquid is incompressible, when it is pushed to the top, if it is too late to drain, the piston cannot go up, which will cause the connecting rod to be deformed or even broken.
