T s diagramm co2. Pressure enthalpy diagram for carbon dioxide refrigerant. There is currently serious consideration of replacing it with r744 carbon dioxide in refrigeration and heat pump applications as well as automotive air conditionong systems. 1 0 2. The current refrigerant r134a has a global warming potential gwp of 1300 with respect to co2.

As a large amount of heat is recovered in recuperators to increase the thermal efficiency high effectiveness is required and therefore the capital cost increases when.
S co 2 supercritical co 2. T s diagram of s co 2 recompressing cycle. The phase diagram for carbon dioxide shows the phase behavior with changes in temperature and pressure. 7 1.
What is the enthalpy value of the gas. A temperature entropy diagram or t s diagram is a thermodynamic diagram used in thermodynamics to visualize changes to temperature and specific entropy during a thermodynamic process or cycle as the graph of a curve it is a useful and common tool particularly because it helps to visualize the heat transfer during a process. From the carbon dioxide diagram figure a 4 of appendix a locate the pressure of 100 psia. For reversible ideal processes the area under the t s.
An enthalpy entropy chart also known as the h s chart or mollier diagram plots the total heat against entropy describing the enthalpy of a thermodynamic system. It shows enthalpy in terms of internal energy pressure and volume using the relationship or in terms of specific. On the right of the figure we have plotted the temperature versus the entropy of the gas. The curve between the critical point and the triple point shows the carbon dioxide boiling point with changes in pressure.
Lines of constant pressure curve from the lower left to upper right on a t s diagram. 30 1. The operating condition is important in the s co 2 heat exchangers. This plot is called a t s diagram.
