T s diagramm co2. The current refrigerant r134a has a global warming potential gwp of 1300 with respect to co2. This plot is called a t s diagram. 30 1. What is the enthalpy value of the gas.

The phase diagram for carbon dioxide shows the phase behavior with changes in temperature and pressure. A typical chart covers a pressure range of 0 01 1000 bar and temperatures up to 800 degrees celsius. Use of the t s diagram carbon dioxide is used in a particular process in which the pressure is 100 psia and the temperature is 100 f. From the carbon dioxide diagram figure a 4 of appendix a locate the pressure of 100 psia.

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.

It shows enthalpy in terms of internal energy pressure and volume using the relationship or in terms of specific. Pressure enthalpy diagram for carbon dioxide refrigerant. The curve between the critical point and the triple point shows the carbon dioxide boiling point with changes in pressure.

S co 2 supercritical co 2. 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. 3 0 7 k j k g o c s 2. 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. 7 1. Lines of constant pressure curve from the lower left to upper right on a t s diagram. Use of the t s diagram.

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. On the right of the figure we have plotted the temperature versus the entropy of the gas. 6 0 1 5 4 1.
