Ph diagram 134a

On the P-H diagram, pressure is indicated on the y-axis and enthalpy is indicated on the x-axis. The upside down U figure shown on the diagram designates the points at which the refrigerant changes phase, ph diagram 134a. The left vertical curve indicates the ph diagram 134a liquid curve and the right vertical curve indicates the saturated vapor curve. The region in between the two curves describe refrigerant states that contain a mixture of both liquid and vapor.

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.

The input condition of the expansion device is determined by the condenser output conditions. In this region there are vertical temperature lines, which increase as enthalpy is increased.

Therefore the intersection of the constant entropy line and the discharge pressure line will identify the final condition of the refrigerant gas leaving the compressor, as shown by point C' in the figure below. In order to properly understand this diagram, it is best to go through the vapor compression cycle on a P-H diagram. The enthalpy lines are the vertical lines. It helps to identify a single user across multiple pages during a single visit to the website with session ID. As the evaporator transfers heat to the refrigerant, there is no gain in temperature, since all the heat is used to convert the remaining liquid to a gas.
