As a teaching tool and aid students some really respond very well to a graft of pressures and temperatures overtime. Fieldpiece SM480V digital refrigerant manifold. Also has a micron gauge built inside.. on a large overhead projector or a few large screen TV is out in the shop in your class. You can actually graph the pressure, temperature, relationship and the cycling and any changes up on the screen record it and save it scroll backwards.. It’s an excellent teaching tool to show old fashion, fluid, drip, and thermal fan clutches as they slightly engage and disengage we’re not always to perceivable to the human eye or ear . An excellent tool to also show the superheat and sub cooling, especially how it doesn’t follow. The rules and procedures we were taught on old fashion, fixed, piston, compressors. Fieldpiece also has remote transducers for pressure recording and excellent temperature sensors with humidity and clamp on thermistors to attach to refrigerant lines to take the temperature of the Refrigerant inside the refrigerant lines to get your superheat and sub cooling .
hi, i have watched lot of your videos whole night. you said high side is on liquid line NOT on discharge line.. so if there is a block on condensor liquid line will not go up like 300. i assume you made typo error as calling as liquid line. pls advise.
Hello Sivaraj, I was correct in saying the high side service port is in the liquid line. On a TXV system, the entire liquid line is high side pressure. The high side service port can either be in the discharge line as you state, or in the liquid line. Thanks for watching.
@@ProfessorPentane thanks much. You said in one of the other video for restricted condenser, having port on liquid line will show lower high side but if we have port on suction side it will show higher on high side. So in TXV if there is a restriction in condenser, how does my high side look like and it seems it doesn’t matter whether it is discharge or liquid. Pls advise. Many thanks I didn’t slept and entire night I watched all your videos
@@sivucit, Watch my video on the "A/C gauge analysis diagnostics: 2006 Buick Lucerne TXV". This is a refrigerant restriction in the condenser, which pressure will be different on high side service port location. In the Buick video, the high side service port is in the liquid line, after the restriction, so it reads low. If the high side service port is on the discharge line, before the restriction, pressure would read high. If there is an airflow restriction through the condenser, then you are correct that both locations of the high side service port will read high. Thanks for the good discussion.
@@ProfessorPentane fantastic. Just to let you know. This is the best channel for AC diagnostics which has real time example for every possible scenario. I never understand the theory. It took me almost 10 years to overcome my ignorance. Appreciate a lot. I will share this channel with my friends. Don’t believe me I didn’t slept whole night finished all your videos

@@ProfessorPentane I made one typo while responding … but if I have port on liquid side NOT suction side it will show lower high pressure
