Handmade Copper Ejectors

This is part two of a three part series to get my blog up to date on my ejector research.  Part I was about ejector theory:  Ejectors in Refrigeration – an Expressor.  Part III is about assembling and testing:  Ejector

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

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

Amateurish Refrigeration Research

I have a High School Diploma, and that is about the extent of my formal education.  My real education comes from years of mechanic jobs, fiddling with and fixing things around the house, building things I need rather than buying

Refrigeration Test Bench – Part III

In Part I, I shared a lot of media relating to my efforts in building a refrigeration test bench.  I intended to build the whole thing from a DIY approach, and utilize a York 210 – Belt Driven Air Conditioning

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

Yet Another Change Of Course

I want to talk about overunity.  Anyone that has looked around this blog knows that I have a special place in my heart for refrigeration, “heat pumps” more generally speaking.  Vapor compression systems have fascinated me for years.  It has

Noodle Soup Village – A Tiny House Community

For twenty eight years I’ve been searching for something.  A mission, a purpose, a place to call home.  I’ve been searching in myself, in others, in culture, books, careers, and geographic locations.  I seek a lifestyle in which my actions

The KillCap Catalogue

I enjoy designing vapor compression machines.  It all started with a refrigerator.  I have thought long and hard on how these mainstays of modern living could be improved and someday I will make some of them a reality.  In the

The Great Gravity Flooded Evaporator

I’ve grown quite fond of the gravity flooded evaporator in the last year or two.  It has a number of advantages over a dry type evaporator.  I’ve discussed some of these in previous posts (here and here) and I will no doubt

1930s Household Refrigerators

The evolution of the household refrigerator is not a well known story.  There seems to be few people interested in the subject.  Perhaps it is not as romantic as the development of the automobile.  Nonetheless, a concerted effort was put

Modular Refrigerator Circa 1935

This curious little gem here is a modular refrigerator evaporator from a US patent granted 1935.  Available here.  The purpose of the invention being that it allows for the removal or replacement of a refrigerator’s evaporator coil (or at least

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

Future Plans

I’ve been thinking quite a lot about refrigerator designs and what steps I’m going to take in developing them.  I tend to take on a lot more than I can chew and then when it all becomes too overwhelming, I

Refrigerator Cabinet Design – Part 2

In Part 1 I complained a good bit about the design of conventional refrigerators.  Since I was a little kid, I thought that surely their must be a better way make a refrigerator more convenient and at the same time consume

Refrigerator Cabinet Design – Part 1

I have some issues with the current state of domestic refrigerators.  Anyone who has read my other posts is probably well aware of this fact.   A Better Refrigerator, The Killcap Refrigerator and Hand Crafted Refrigerators.  I have a great deal of

“Free” as in “Freedom”

A part of technological design I think is important, is the distribution model chosen.  In a dominantly capitalist economic system, marketability seams to be a deciding factor in the success of an idea or even whether anyone bothers building something
