Carrier Chiller 30GX - HVAC Training

#carrier #carrierchiller #30gx #hvacschool #hvactrainingvideos #hvactroubleshooting #hvac #hvacr #refrigeration #hvacrvideos #hvacsurvival
Another hvacr videos to help show hvac troubleshooting. If you are considering joining the hvac trade I highly suggest getting hvac training from a trade school. Online hvac training videos only get you so far. From experience hvac school is the way to go. No matter what you call it HVAC, HVACR, Refrigeration, Air Conditioning, Chillers, Low Temp, High Temp, Mechanical, ect, we are all blue collar in this hvac life.

I remember subscribing to your channel shortly after this video was made....good ole days

[@anantharao3573]

Excellent. Helped me to understand 30GX175 at my workplace. This is rather advance explanation which requires some pre-requisite in refrigerant cycle to understand better. nevetheless, there isn't many videos like this which describes real chiller components. Mostly just talk about refrigerant cycle. Thank you once again. I benefited a lot.

[@ralmeraz100]

Thanks for posting.👍🏼

[@akmprism8642]

Good content. Thanks for explaining it so thoroughly.

[@brandonwalker4842]

That motor cooling solenoid valve actually has a fixed orfice. Food for thought! 👍 great vid

[@brianmillion-osborne6747]

Great videos. I enjoy reading manuals but I enjoy the videos more.

[@Stevehevessy]

Great video,as a new chiller tech these videos are really helpful

[@HVACTIME]

awesome!

[@sidtrex1]

Thank you so much I’ new on this one I’ has Carrier water cooling model 30HXA 106RZ. Still working on she it leaking all over on Compressor I’ leaning a lot from your. V. D O

[@patrickmccuiston7762]

Great Video @9:20 Carrier removed the check valve (on later models)that was in the oil filter cavity after they found out that oil pressures where wrong. If you replace the oil filter they advise removing "Gutting" the check valve. I have never had good fortune for a Carrier Screw to hold back pressure to change an oil filter. I closed Suction valve,oil line valve, and removed oil solenoid coil, they still bleed refrigerant. I do complete refrigerant recovery to service these.

[@gaminidissanayake5465]

thx bro for sharing your knowledge. god bless you.

[@adrianmoran1041]

Thank you for this video.

[@johngrayer7773]

Great video mate, like it. I did the GX/HX course in UK when they first came out with the open economizers. The economizers were described as "capacity increasers" not "efficiency increasers". Could be different with your plate heat exchanger type though. Cheers.

[@mohammedzuhd2600]

Really you're superman Thanks a lot

[@brandonwalker4842]

The economizer is another name for hot gas by pass. Just another name. It does have multiple purposes as in cooling motor with cool suction gas along with sun cooling liquid going to exv. 26:52 Carrier is trying to maintain a 200 degree motor.

[@ziaarnie3694]

Awesome content brother , please explain complete power and control wiring diagram in paper along with practical . Thanks

[@Drew206619]

I couldn’t thank you enough for this video I have 2 neglected 30HXC process chillers at a large mill in WA that I have inherited I’ve gotten after hour calls at 2 am a couple months ago. Been in the trade for a while now I just haven’t put my hands on chillers Trial by fire Any information helps me and I thank you again.

Hi Sir, hoping you are enjoying best health. Sir, in our power plant there are three set of AC Chiller 30XA0502G with compressor A and B. Right now Electric Box thermostats or electrical interlock failure alarm appearing

[@sekarsankar7606]

As refrigerant circuits are different and water enters from one side and exits at the other side, how I should check the evaporator approach as we have only one chilled water outlet temperature sensor at the outlet of evaporator, so the circuit (if in operation) nearest to the chilled water outlet should be considered for Evaporator approach calculation right?

[@mansourghadhban236]

Good job Go on we hope to see how change control in other one New practically step by step

[@adrianmoran1041]

Looking for the ball valve at compressor when needing to change out external oil filter. Also how would I replace the oil switch located on the bottom of the separator. Should I reclaim all the gas for the circuit or hole system?

[@babaolowo35]

Thanks

[@omkumarsubba3967]

i want to know swhat is the dischargegas thermostore failer

[@username5850]

Just wanted to let you know that your description of the unloader operation is not quite correct. These compressors have no slide valve, and are not full variable capacity like the later Carlyle 06T, and similar Trane and York screws. The two unloaders are similar in action to the suction unloaders on a recip compressor, they are only on/off poppet valves that load the compressor from nominally 45% capacity with both off, to nominally 66% and 100%. But, great video, keep it up. I wish I'd had this channel to watch back when I was starting out.

[@nathandaubis819]

SOLID VIDEO...LEARN SOMETHING..QUESTION..HOW DO YOU ISOLATE THE EXTERNAL OIL FILTER FOR CHANGING.

[@HVACTIME]

There are supposed to be iso service valves on either side.

[@user-tp3jh4jt8n]

Do you know what type of oil we can use for this compressors?

[@Lc14270]

brother i have a issue loss comunication with compressor protection module 2 what is this?????? can you explain me about fault

[@brandonwalker4842]

Dare you to hold enter and escape at the same time. If ya know you know! 💪

[@abhiabhi2194]

30GX 255 alarm suction pressure how can i solve this one

[@aaronhutchinson2680]

How do you remove the fan blade

[@nageshan9947]

Discharge pressure not building and suction not increases what's problem

[@TechnicalBrainHVAC]

sir i have a problem in 30gx chiller its showing alarm low cooler temp alarm what should i check its working just 2 minuts and off

[@HVACTIME]

Have you verified your EXV is controlling properly? Power cycle the controls and feel if the EXV operates.

[@TechnicalBrainHVAC]

@@HVACTIME dear sir i check everything is fine even exv also opening 54 to 67 % but compressor filled with liquied also motor cooling valve become frosty and compressor motor side full moisture.

[@HVACTIME]

Discharge temp, suction temp, and motor temp sensors having issues.

[@TechnicalBrainHVAC]

@@HVACTIME there is only one sensor like thermistor only on discharge port. Other 4 transducers discharge suction oil and economizer Water inlet and outlet temp sensors. I appreciate if you will guide me EXV works on which sensor demand.

[@TechnicalBrainHVAC]

@@HVACTIME alarm is showing 57

[@omkumarsubba3967]

sikr discharge gas thermostore failer how to solve

[@HVACTIME]

Usually means the discharge temp thermistor is out of calibration. Its is usually in a well so easy to replace. Its a few inches down the line from the compressor.

[@omkumarsubba3967]

@@HVACTIME thank you sir

[@IRONDICKMECHANICALHVACdavis]

Reset the alarm.

[@mrbugenhagen3364]

Those o-rings have griefed me on multiple occasions. Atleast the ones Carrier provide seale, Bitzer on the other hand leaks even more with a new set, do not ask my how i know 😡. Just get one fabricated that is one size bigger.

[@KeithSnyder-qc7in]

Those chillers are JUNK! Especially the float chambers. Nothing but headache

[@IRONDICKMECHANICALHVACdavis]

The condenser fan run in reverse during low ambient condition.

[@HVACTIME]

They dont run in reverse. The draft from the other motors will make them spin backwards but their not running with power to them in that state.

Sir i need help, if u can share nmber pl
