What specific volume corresponds to -18 degrees?

The specific volume at -18 degrees Celsius is a critical parameter in the analysis of refrigerants, particularly in systems utilizing ammonia or other common refrigerants. The specific volume is the volume occupied by a unit mass of a substance at a given temperature and pressure, and for refrigerants, it changes significantly with temperature variations.

For refrigerants like ammonia, operating conditions such as temperature and pressure determine their specific volume. At -18 degrees Celsius, the specific volume typically falls within the range of the values provided. The value of 0.0237 corresponds to the specific volume of the refrigerant at this temperature and under typical pressures in refrigeration applications, making it a relevant and practical answer for operators working with these systems.

Understanding the specific volume at various temperatures helps in calculating refrigeration loads, determining the performance of refrigeration cycles, and ensuring efficient operation of refrigeration systems. Accurate knowledge of these properties is integral for maintaining optimal system performance and energy efficiency in industrial refrigeration applications.
