Videos are coming. Thanks for the kind words!
In my classes we have a few rotary compressors and they have shiny black accumulators on them. The students call this a drier quite often because our alco display driers look very similar.

Thanks Chris! Maybe we can collaborate sometime.
I agree with the videos as well. Also love the podcast. Is a daily listen on the rides in the work van!
Thanks Josh!
I haven’t done any quick quizzes like this since I got my Journeyman ticket 11 years ago.
Made me think back to school. Ha. Good stuff. Thanks. Keep them coming.
Recently started listening to your podcasts. Good stuff. Maybe you could do an episode on those fun carrier/Bryant heat exchangers they were having issues with.
Have to disagree with sight glass question. If you charge past the full sight glass on a cold day the system will be overcharged at higher ambient temperatures with liquid banked up in the condenser and high discharge temperatures. Also once you have charged past a full sight glass you can easily overcharge a system. The low sight glass may be due to flash gas caused by insufficient subcooling in the condenser and liquid line and not low charge,exacerbating the problem, therefore all the answers are incorrect. Also what is a cold control? It must be an American expression. Please be more specific as any control on the low side of the refrigeration system could be called a cold control. I take it you are referring to a refrigeration evaporator or coil thermostat as opposed to a room thermostat.
