- Typically thermophysical properties of refrigerants are modeled using an EOS (equation of state). Cubic EOS are most commonly used when there is very little experimental data available. Some of the most common cubic EOS are reported by Walas1. An alternative EOS is an extended corresponding states equation. An extended corresponding states equation relates the properties of on fluid to another. The extended corresponding states model is typically more accurate than a simple cubic EOS but it can require more information about the fluid being modeled.
An extended corresponding states model that was specifically designed for refrigerants was proposed by Huber and Ely2. An extended corresponding states model references a fluid that has a large amount of accurate experimental data. In the model proposed by Huber and Ely the reference fluid used HFC-134a, a fluorocarbon with similar physical chemical characteristics to HFO-1234ze. In order to accurately describe the thermophysical properties and a fluid Ely and Huber used shape factors that are correlated from experimental data, typically vapour pressure and saturated liquid density. The shape factors give the corresponding states EOS the ability to accurately model the fluid of interest - GLP compliance:
- no
- Type of method:
- other: modeled using an EOS (equation of state)
- Key result
- Boiling pt.:
- -19 °C
- Atm. press.:
- 760 mm Hg
- Conclusions:
- The boiling point of HFO-1234ze is -19 °C.
- Executive summary:
The boiling point of the substance was determined by modelling modeled using an EOS (equation of state) and was found to be -19 °C at 760 mm Hg.
