Office Hours: Live Appliance Repair Training Webinars with Samurai Appliance Repair Man

The Samurai hosts regular live webinars to help students understand the course material and for open Q&A. Think of the webinars like Office Hours where students can drop by for extra instruction and ask questions about their course work. Some of the Office Hours webinars are recorded and students who have purchased Bundle 1 may watch the webinar recordings here.

If you plan on attending a webinar, you must RSVP using the form at the bottom of this page. The connection details are unique for each webinar, so you need to RSVP each time you plan to attend.

Office Hours are always on Mondays from 7:00 pm to 8:00 pm Eastern Time (adjust your time zone accordingly), and usually occur at least twice a month. The duration of the sessions varies according to attendance and questions. We try to end by 8:00 pm but may go longer based on Q&A. The topics of the webinars also vary but will be announced below.

How to Attend a Webinar

Our web meetings are powered by which is the best service of its kind out there. You can participate using any Windows or Mac desktop or using any Android or Apple device. Come git you the free software or app to enhance your learning experience:

1. Arrive early to make sure your connection is working! Also, if you show up late for the webinar, you'll be lost.

2. Enter your name at the "knock to enter" window on the meeting page- if you leave it blank, you won't be able to enter.

3. Watch this ultra-short video on how to use your control console while you're in the web meeting.

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. Here are the topics we're going to discuss:

  • 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)

NOTE: If you didn't attend the first webinar or haven't watched the two-part webinar recordings of them, don't bother coming to this one because you'll be lost. Doing the homework assignment as well 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.

When: Monday, November 6, 2017, @7 PM ET
