of the P-T chart/application, let’s . review briefly the refrigeration sys-tem and examine exactly how the pressure-temperature relationship can be applied. The refrigerant in a refrigeration sys-tem will exist in one of the following forms: 1. All liquid. 2. All vapor. 3. A mixture of liquid and vapor. Figure 1. illustrates the form in which

Distinct liquid and vapor states do not exist. R-744 Carbon Dioxide Refrigerant Pressure Temperature Chart By Alec Johnson May 17, 2019 Regardless of what system you are working on rather it is a home air conditioner, a vehicle’s air conditioner, a supermarket refrigeration system, or a large scale industrial application they all have one thing in common: Pressure. Pressure enthalpy chart for R744 The pressure enthalpy chart in figure 4 shows the critical point and the extent of the transcritical fluid region. 1 The GWP values are from the Intergovernmental Panel on Climate Change, 4th assessment report: Climate Change 2007 2 GWP for R407A from EN378 Figure 1: R744/CO2 phase diagram The triple point occurs at 4.2 bar (60.9 psi) and -56.6 °C (-69.8 °F).
