Summary of reciprocating compressor
Video Summary
The video explains the functioning of a reciprocating compressor, which compresses refrigerant vapor using a piston within a cylinder, similar to an automobile engine. Key features include:
- Mechanism: The piston is driven by a crankshaft via a risk pin and connecting rod. Depending on the design, reciprocating compressors can have one or more cylinders arranged in various configurations (in line, opposed, or V-shape).
- Valves: Each cylinder is equipped with a suction valve and a discharge valve, which enable the compressor to pump refrigerant vapor against pressure differences. These valves are typically located in the cylinder head and connect to the high or low pressure sides of the system.
- Compression Process:
- The cycle begins with the piston at top dead center (TDC). As it moves down, it creates a vacuum that opens the suction valve, allowing low-pressure refrigerant vapor to enter the cylinder.
- Once the piston reaches the bottom of its stroke, it moves back up, closing the suction valve and compressing the vapor. When the pressure exceeds that of the discharge line, the discharge valve opens, expelling the compressed vapor.
- This cycle repeats with each revolution of the crankshaft.
The video also encourages viewers to engage with a learning activity at the end.
