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 […]

Some careers, such as the more prolific positions in journalism and broadcasting, require lots of networking for you to land a job. A candidate’s appeal may depend almost entirely on who they’ve rubbed elbows with and which companies they’ve worked for.

It prepares the refrigerant for the condensing process, which is crucial for heat rejection.  However, some refrigeration methods don’t require a compressor. In this article, we’ll look at those methods and their applications.   Gas movement without compressors As you […]
