A compilation of thermodynamic and physical data for the refrigerant designated “134a” is essential for system design and operation. This data, typically presented in tabular format, includes properties such as temperature, pressure, density, enthalpy, entropy, and specific heat at various states. An example might show saturated liquid and vapor properties at different temperatures, or superheated vapor properties at different temperatures and pressures. These tables often include transport properties like viscosity and thermal conductivity.
Access to accurate data is crucial for engineers and technicians working with refrigeration and air conditioning systems. These data facilitate accurate calculations for system performance, component sizing, and charge determination. Historically, these tables were derived through meticulous laboratory measurements and complex calculations. Their availability significantly advanced the field of refrigeration by enabling precise system design and optimization. Understanding the thermodynamic behavior of 134a is vital for efficient and safe operation of systems utilizing this refrigerant.
