. Refrigerant (R-134a) Thermodynamic Properties (ENG Units) 2 Equations The MBWR equation of state was used to calculate the tables of thermodynamic properties. It was chosen as the preferred Ideal Gas Heat Capacity (At Constant Volume) Co v = a + bT + cT 2 + dT3 + f/T2 For SI Units Co v = kJ/kgK T is in K = C + 273.15 It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges. Therefore in a normal R134a, the low-pressure side is 90 degrees or less, and the PSI should be close to 30.
