Fundamentals & Science

I got in one of these tiny torches the other day to experiment with brazing aluminum in tight spots, and one of the techs walked in and asked, “What type of torch is that?” I answered, “It’s oxy/acetylene.” He picked it up and looked at it a bit, then asked, “Does that get hot enough […]

This article was written by my buddy and Canadian Supertech Tim Tanguay. Thanks, Tim! This P/E chart shows R410a at 100°F saturated condensing temp, 10°F SC, 40°F saturated suction temp, 20°F SH at the compressor. The green highlighted thumb shape is the saturation zone. Everything that occurs in the saturation zone is a latent (change […]

Breaking the Sound Barrier So, what do you think of when you hear an “ideal gas?” R22, R12 maybe… natural? Take a look at the F-18 above. It’s breaking the sound barrier, and that cloud is a shockwave. It has nothing to do with this article, but I think it’s pretty darn cool! An ideal […]

The gas laws. We all learned about them in school and promptly forgot all about them. I really think that we need to dig our books out, dust that information off, and work to understand and apply it. Many will say that nitrogen pressure doesn’t change with pressure like other gasses. That is false, but […]
