Can the log p-h diagram be used for other types of refrigeration cycles, such as absorption refrigeration?

Yes, the log p-h diagram can be used for other types of refrigeration cycles, including absorption refrigeration. While the specific regions and processes may differ, the log p-h diagram provides a general framework for analyzing the thermodynamic state changes of the refrigerant. By adapting the diagram to the specific characteristics of the absorption refrigeration cycle, engineers can use it to analyze and optimize the performance of these systems.
