Long overdue for an update, I have these backlogged photos of my journey towards building a better refrigerator, and I feel I need to get these published so I can pursue further writing. See Part 2 The last nine months…

Ejectors in Refrigeration – an Expressor
Having developed a degree of confidence with copper brazing, and reaching the potential limits of what can be learned, I have decided to move past my original work with the Ebullator. I document my progress with that device in Refrigeration…

Sealing Thermocouples Into Refrigeration Lines
I thought I would provide some media to help describe my method of installing thermocouples into refrigeration lines. I’ve found in working with the Ebullator, that the temperature readings I was getting by taping thermocouple tips to the outside of…

Refrigeration Test Bench – Part II
In Part I, I summarized my efforts to build myself a testing platform for refrigeration projects. I cut that post short at about the point where I began doing some heavy brazing work. Also, the amount of media in that…

Refrigeration Test Bench – Part I
This post is going to be a bit long because it will be largely media, since I’ve done no writing for the last several months and have been busy in my shop. I will let the pictures and videos do…
Refrigeration – Back at it!
Oh my; where to start? I’ve been away from the blog so long, and have so much to discuss, I fear I know not where to start. I’ve written quite a bit about refrigeration in the past, but that…

Trying Not to Blow Myself Up
I advocate hydrocarbon refrigerants for vapor compression systems whether it’s refrigerators, dehumidifiers, split systems, whatever. There are a lot of advantages to them over proprietary cocktails like R-134a, R-22, 410a and so on. First of all, they are naturally found…
