      [Webinar] Samurai's Sealed System Sleuthing Secrets - 10/30/2017 @7PM ET   10/19/2017

      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 problem using strategically chosen and skillfully interpreted temperature measurements.  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.

  • 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: Basic Refrigeration System Thermodynamics

We're venturing down the rabbit hole- this webinar is the first part in a multi-part webinar series on understanding how the sealed system in a refrigerator works. In this first session, we're going to be laying foundational concepts that will be used in subsequent webinars. So if you miss this one, you'll be lost in the later sessions. 

In this first part, we're going to discuss and understand:

  • Pressure and vacuum units of measurement
  • Energy and work: BTU vs. BTUH
  • Latent and sensible heats
  • Saturation temperature
  • Boiling point and phase change
  • Enthalpy
  • The Pressure-Enthalpy (P-H) diagram 
  • Using the P-H diagram to analyze an ideal refrigeration cycle
  • Refrigerant pressure-temperature saturation tables
  • Superheat and subcooling

We'll also look at pressures, superheats, and subcooling at various points around a real-world R134a refrigeration system and plot these on a P-H diagram. You'll need a set of R134a P-T tables or the Danfoss app.

When: Monday, October 2, 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.
