The RSES Member Webinar series continues with an exploration into using the PH Diagram as a service tool.

This webinar will provide a general overview of the basic pressure-enthalpy (P-H) diagram. This diagram shows the properties of the refrigerant as it travels throughout a complete cycle. Studying this diagram allows a technician to understand the changes that occur to refrigerant as it travels through the various system components.

This enables a technician to see the cause and effect of changes made to the operating system. For example, how does excessive suction line superheat effect the operation of a system or how does suction line pressure drop effect the capacity of a system?

Your presenter, Joe Marchese, CMS, has designed this webinar to show how this diagram also allows a technician to calculate a system's mass flow rate, refrigeration capacity, heat of rejection, heat of compression and several other properties of a system.


RSES added monthly webinars free of charge for members in early 2013.

Much like the RSES Journal, periodic technical bulletins (SAM chapters) and their respective online archives, the monthly webinars are geared to help you with technical information you can apply on the job.

Presented by some of the industry’s most sought-after technical experts, sessions range from basic to advanced levels on topics spanning the HVACR spectrum.  Participation in live webinars earns CEHs automatically, and all webinars are recorded for future viewing.

Typically held the 4th Wednesday of each month, RSES members should watch their email for registration information!
