An important skill that is necessary to pass the pe exam is the ability to navigate a refrigerants pressure enthalpy diagram and to be able to follow the vapor compression cycle on the p h diagram.

How to draw an enthalpy diagram. The pressure enthalpy chart as shown in fig. If delta h is positive then it is an endothermic reaction and the product energy is higher than the starting energy. 2 displays all the pertinent properties for a given refrigerant in this example r22.

The blue line on the left of the bubble represents the 100 saturated liquid line. Horizontal lines in such a diagram correspond to different absolute values of enthalpy h. The mechanical pe exam covers the topic of refrigeration.

The bubble to the left is the portion of the diagram where the refrigerant is in the saturated condition. The following post gives background information on the refrigeration cycle as shown on the pressure enthalpy diagram. Enthalpy diagrams are an easy way to see how the energy changes in a reaction over time.

Use the following enthalpy diagram to answer the following questions. Endothermic the products are at a lower energy level. Use the following enthalpy diagram to answer the following questions.

Its difficult to illustrate on this but basically the x axis is the progress of the reaction going from reactants to products the y axis is the enthalpy depending on whether it is an endothermic. Audiam publishing latinautor peermusic ascap third side music latinautor abramus digital and 8 music rights. We draw them by knowing the delta h of the reaction and the activation energy.
