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…

C-3_H-8…Propane!
I had a feeling the other night, that we were dangerously low on propane. My fears were justified as the heater began sputtering the next morning. I shut everything down, including the refrigerator until I could get some propane. It…

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…
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…

Discourse On Dehumidifiers
I’d like to talk about dehumidifiers; what they are, how they work, design failures and improvements I’d make. The dehumidifiers I write of are a specific kind, but probably the most common. They are the small white plastic towers people…
