    This is an excellent short (14 pages) technical article written by Dave Demma, a Senior Application Engineer with Sporlan. He explains how to use the pressure-enthalpy (P-H) chart to understand how a refrigeration cycle works and how to apply this to various troubleshooting scenarios. Don't let the "engineer" scare you-- the math is minimal and simple, nothing more complicated than arithmetic: adding, subtracting, multiplying, and dividing. The explanations are clear, plain and non-geeky and he uses lots of illustrations. It really is a masterpiece of teaching and making something complex understandable by anyone, regardless of your technical background. If you understand or are at least familiar with the P-H chart (which we covered in detail in the Refrigerator Sealed System Thermodynamics webinar series), you'll get a much better understanding for saturation, superheat, subcooling, and system pressures. This copy has my highlights of key points.

    Note: This webinar was rescheduled from its original date on October 30 to November 6. Be sure to subscribe to our newsletter for updates! Who: Professional Appliantologists, Senior Appliantology Fellows, and Legacy Tech members at Appliantology Master Samurai Tech Academy students enrolled in the Refrigerator Repair course Mr. Appliance® Academy students enrolled in Bundle 1 What: Practical Sealed System Thermodynamics In the last session on 10-2-2017, we laid the theoretical groundwork for understanding how sealed systems do what they do: move heat from a refrigerated compartment to the outside world. We looked at basic refrigeration concepts like pressure energy work enthalpy entropy saturation superheat subcooling and we got acquainted with the P-H diagram which we used to understand the ideal refrigeration cycle. We looked at the thermodynamic states of the refrigerant throughout the cycle: compression, condensing, expansion, and evaporation. Then we looked at a real-world refrigeration cycle with temperature and pressure measurements around the system and plotted it on a P-H diagram. We left off with a homework assignment where we're given pressure and temperature measurements around a refrigeration system and we have to determine what state the refrigerant is in: liquid, vapor, mix, saturated, superheated, or subcooled. This is where we'll pick up in this webinar. Having laid some theoretical groundwork in the last webinar, we're going to focus on practical considerations in this one. That means quick n’ dirty techniques for diagnosing sealed system problems using strategically chosen and skillfully interpreted temperature measurements. Here's what we'll be doing: Brief review of the Pressure-Temperature relationship in sealed systems Review homework from the first session on 10-2-2017. Home refrigerator practical design and operating rules-of-thumb useful for troubleshooting Practical application exercises Troubleshooting scenario exercise Techniques for making system temperature measurements for determining superheat and subcooling Sealed system diagnosis homework assignment (to be reviewed in the next webinar in this series) If you attended the first webinar in this series, this is your payday! We’re going to apply that keen, penetrating insight you now possess into money- and time-saving shortcuts you can use to diagnose real-world refrigeration systems on service calls. Also, make sure to do the homework assignment because this will let you test yourself to see whether you understood the key concepts or not. We're going to be proceeding on the assumption that you understand basic concepts like phase change, saturation, superheat, subcooling, etc. If you did not attend the first webinar or haven't watched the two-part webinar recordings of them, you are still welcome to attend, but may be baffled by parts of this one. When: Monday, October 30, 2017, at 7PM Eastern Time SHARP (adjust your time zone accordingly). Where: All of our web meetings are powered by Join.me. For the connection details, see below.
