The log P/h diagram offers several advantages over other types of refrigerant property diagrams. The logarithmic scale for pressure allows for a more detailed representation of the low-pressure region, which is critical in refrigeration systems. Additionally, the diagram provides a clear visualization of the refrigerant’s behavior during phase transitions, making it easier to analyze system performance and identify potential issues. The log P/h diagram is also more comprehensive than other diagrams, as it includes both thermodynamic and transport properties of the refrigerant.
