Ph diagram 134a

On the P-H diagram, pressure is indicated on the y-axis and enthalpy is indicated on the x-axis. The ph diagram 134a down U figure shown on the diagram designates the points at which the refrigerant changes phase.

Help Center Help Center. The P-H Diagram 2P block plots a p-h diagram of the pressure with respect to the specific enthalpy of a thermodynamic, two-phase fluid. A p-h diagram indicates the fluid state at key points during a thermodynamic cycle. Each numbered point on the diagram indicates the fluid state after a dynamic process in the refrigeration cycle:. Use a Mux block to combine the pressure signals. Connect the output signal to the P-H Diagram 2P p port. Use a Mux block to combine the converted specific enthalpy signals and connect the output signal to the h port. Before running the simulation, double-click the P-H Diagram 2P block, then click the Select fluid properties button to set the network fluid properties. If you do not select the fluid properties, the block uses the default two-phase network fluid, which is water.

Ph diagram 134a

The pressure-enthalpy diagram is the most common graphical tool for analysis and calculation of the heat and work transfer and performance of a refrigeration cycle. The change in pressure can be clearly illustrated on the p-h diagram. Also, both heat and work transfer of various processes can be calculated as the change of enthalpy and at easily shown on the p-h diagram. The saturated liquid line separates the sub-cooled liquid from the two-phase region in which vapor and liquid refrigerants coexist. The saturated vapor line separates this two-phase region from the superheated vapor.

If you read my previous post about sealed system basics , you know that understanding the thermodynamic states of refrigerants saturated, subcooled, and superheated is essential to sealed system troubleshooting. In that post, I explained these states in terms of a simple pressure-temperature table.

Cooling takes place as heat flows from the hot refrigerant gas to the condenser cooling medium.
