T S Diagramm 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.

T s diagramm co2. 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. On the right of the figure we have plotted the temperature versus the entropy of the gas. The current refrigerant r134a has a global warming potential gwp of 1300 with respect to co2.

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. 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. For reversible ideal processes the area under the t s. 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. From the carbon dioxide diagram figure a 4 of appendix a locate the pressure of 100 psia.

As described on the work slide the area under a process curve on a p v diagram is equal to the work performed by a gas during the process. The curve between the critical point and the triple point shows the carbon dioxide boiling point with changes in pressure. This plot is called a t s diagram.
