MICRO GAUGE INDICATES HIGH MOISTURE CONTAMINATION

- There’s such a huge difference in time and how quickly you could get below 500 µm or even 200 µm on the old refrigerant mineral system. Compared to a vehicle what has PAG or POE oil that is moisture saturated 
love your videos bruh im trying to learn, i charged my truck right now after replacing the drier and discharge hose, its almost 12am. got the vent air down to 35 degrees!
can you post a link to a good explanatory video about mineral oil and ac systems please
ua-cam.com/video/Zjb60XXHCEs/v-deo.htmlsi=PF1zQCfhKz0aTzfe
If you use the search term in UA-cam
(“ retrofit mineral oil refrigerant”)
It will bring up some video recommendations
UPDATE again. I have now placed 3 thermocouple on my HVAC system pipes. I done some logging. Poor thing mu compressor OUTput is as hot as 88C / 191F , at creeping traffic jam in a 45 minutes drive after a heat soak and my underhood temperature is usually 4C to 5C hotter than compressor, so it heats up the compressor too. Ambient temperature for this data is 28C or 83F and at night.
Condenser output is good, 55C / 131F when compressor that hot.
EVAP-out pipe between 5 to 7C ( 41-45F )
Humidity is minimum 65% RH, usually 90% RH in daytime.
Living in tropical country, I pity this Denso compressor life.
I have not log 35C ( 95F) ambient yet and day time.
@@suryaprihadi2258 as long as the DENSO compressor never has moisture and air mix with the refrigerant and the condenser is kept clean, and the fan never breaks down the compressor will survive
It’ll just have a hard life
@@coldfinger459sub0 yes high stress life. R134a critical temperature is 102C, dang. The IHX end i measured at LP port body, can be as high as 16C where evap out at approx 4C to 5C. So liquid line probably cooled down by 10C or 18F. Impressive for such a short IHX
@@suryaprihadi2258 and as a rule of thumb
👍
Measured roughly 6 inches from the compressor. The temperature of the pipe temperature on the inside of the cylinder is roughly 50°F to 75°F hotter at the point of generation. .
At what temperature does the oil start showing suffering? . To thermal breakdown and degradation.
Which is accelerated in the presence of H2O and O2
@@coldfinger459sub0 my thermocouple at compressor output pipe skin is approx 3 inches away from the connector interface/coupler of compressor. By 5 inch it is the hose crimping already. Using Flir Thermal imager , compressor overall body also showing average 85C.
@@suryaprihadi2258 clean off the metal areas that you want to test temperature with your thermal imager with some acetone and a scrub brush
And then spray them with some Weber flat, black spray, paint or flat black spray paint meant for exhaust manifold
This will give you the most accurate temperature measurement with your thermal image camera .
