When given a pressure of 600 kPa and a temperature of 25°C for R-134a, the values may not align in the same row of the refrigerant tables due to superheating. The pressure corresponds to a saturation temperature of approximately 21.58°C, indicating that the refrigerant is likely in a superheated state at 25°C. Since the superheated table does not list a value for 25°C, interpolation is necessary between the properties listed for 21.58°C and 30°C. This process allows for accurate determination of the refrigerant properties at the specified conditions. Understanding this interpolation is crucial for effective refrigerant management and system performance.
