What is the maximum compression ratio in a reciprocating compressor?

The maximum compression ratio for a reciprocating compressor is typically around 12:1. This value is based on the design and mechanical limitations of the compressor components, as well as the thermodynamic properties of the refrigerant being used.

When the compression ratio exceeds this value, several issues can arise, such as overheating, high discharge pressures, and decreased efficiency. Therefore, manufacturers often recommend not exceeding this limit to ensure optimal performance and longevity of the compressor. Additionally, a compression ratio of 12:1 strikes a balance that allows the compressor to operate effectively while managing factors like pressure and temperature within acceptable ranges for typical refrigerants.

Values above or below this ratio reflect different design considerations or applications, but 12:1 serves as a widely accepted practical maximum for general use in various industrial and commercial refrigeration systems.
