Modular Refrigerator Project Update- Part 1
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…

Beginning the Modular Refrigerator
Beginning a few weeks ago, I’ve embarked on a project to construct a modular, long lasting cooling system for domestic purposes. I’ve outlined my reasoning for this elsewhere on this site. 100 Year Fridge The majority of my documentation is…

Ejector Assembly Construction
This is a three part series on refrigeration ejectors. Part I on theory, is Ejectors in Refrigeration – an Expressor, and Part II on manufacturing techniques, Handmade Copper Ejector. There is a lot of video media, so I will jump…

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…

Cannibalizing the Ebullator
I’ve moved on, in regards to what I think can be learned from the first flooded evaporator system, I have been calling “The Ebullator”. Far too many limiting features were preventing me from moving on to the next step in…
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…
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…
