Pressure Enthalpy Without Tears

Enthalpy? A fancy word for heat!

Over the years, much has been written on the subject of pressure enthalpy and most of it is geared toward engineers. This program presents the important concepts of pressure enthalpy in a manner that will appeal to the service technician. Each refrigerant has its own properties and these properties are compiled on the pressure enthalpy chart for that particular refrigerant. The pressure enthalpy chart enables us to create a complete picture, or "snapshot" of the entire system. With a completed pressure enthalpy plot, we can evaluate the major system components as well as calculate latent and sensible heat transfers.

This course is narrated by the author, Eugene Silberstein, M.S., CMHE, BEAP, and starts by reviewing the basic vapor-compression refrigeration cycle, as well as the concepts of superheat, sub-cooling and the pressure/temperature relationship. The course then turns to the pressure enthalpy chart, giving an overview of the meaning and purpose for every line on the chart. Simplified charts are used to clarify the explanations. The plotting of actual systems follows next. The completed plot allows for the evaluation of various system parameters and the calculation of many system characteristics, including system capacity and system efficiency. It is during this evaluation process that system problems can be easily identified. Once the concepts of pressure enthalpy have been mastered, the participant can truly appreciate this tool and its usefulness to effectively and accurately start up, troubleshoot, and evaluate air conditioning and refrigeration systems.

Upon completion of the course, participants will earn a CEU certificate.
