【Q&A Question 171】June 20, 2018: Briefly explain why the cooling water for the compressor enters from the bottom and exits from the top. This is to ensure that there is sufficient cooling water in the cylinder water jackets, thereby achieving adequate cooling. When the water supply is interrupted, the water still present in the cylinder water jackets continues to cool the compressor cylinders, preventing them from overheating immediately.

It is mainly to completely remove air from the cooling water pipes and fill them with cooling water.
To ensure that there is sufficient cooling water in the cylinder water jackets for adequate cooling, when the water supply is interrupted, the water remaining in the cylinder water jackets continues to cool the compressor cylinders, preventing them from overheating immediately.
The cooling water, being a cold substance compared to the compressor body, experiences an increase in latent heat after heat exchange; as a result, the hot fluid rises, facilitating better heat exchange
The cooling water gradually heats up, the hot water rises, resulting in an excellent cooling effect.
Increase contact time and cooling effect for better cooling.
Answer: To ensure that there is sufficient cooling water in the cylinder water jackets for proper cooling, when the water supply is interrupted, the water still present in the cylinder water jackets continues to cool the compressor cylinders, preventing them from overheating immediately.
In this way, the water jacket of the cylinder ensures an adequate supply of cooling water, thereby achieving the purpose of cooling; even if the water supply is interrupted, there is still water in the cylinder’s water jacket, which prevents the cylinder from overheating
