Late to the party but thank you for what you are doing!! I just started listening to the podcast and watching your videos and it is amazing! One day at a time and keeping up with my learning. Thank you sir!

[@RefrigerationMentor]

It is never too late to learn. Thank you for investing in yourself and your refrigeration knowledge. You can find more great content here linktr.ee/refrigerationmentor

Thank you very much. I really appreciate what you have done and continue to do for our industry!

[@RefrigerationMentor]

Our pleasure!

Nice video

[@Tonygolda]

Brand new service tech to the trade (almost a year into it and thrown to the wolves) Just so happens I got the email this morning for this video. And yesterday I had a compressor fail. Broke it down and found that it had a bad valve plate. I will definitely be watching this video again while I trouble shoot the issue. A piece of the valve plate broke off where the pistons push through. I’m still learning the correct terminology so I apologize.

[@RefrigerationMentor]

It’s so good to hear that you are taking the compressors apart and inspecting them.

Yes thank you so much loving this better than my lecturer

[@RefrigerationMentor]

You're very welcome!

Great Trevor 👍

[@RefrigerationMentor]

Thanks 👍

[@mrtince]

Yes, everything you said is really important, but it is very important to run the system at a superheat value suitable for the design. While a high superheat value may cause overheating in the compressor, a low superheat value may cause liquid refrigerant to reach the compressor. Super heat control must be performed, especially in systems with long distances between the evaporator and condenser or in systems where the suction pipe has to be replaced (there may be a need to move the outdoor unit).

[@RefrigerationMentor]

All valid points. Thanks for sharing.

Thanks

Your Welcome!

[@toyinorodare4072]

Thank you for this Update. What is the formula to convert from °F to K?

[@RefrigerationMentor]

How I was shown was divide °F by 1.8 so 20F/1.8 = 11K

[@amoldhakane1124]

What will be the effect on discharge line temperature if we put the compressor in the path of condenser airflow?

[@RefrigerationMentor]

It will reduce the temperature of the discharge as the hottest part of heat of compression happens inside the compressor itself. Great question!

[@tukamushabadickson6811]

What is the standard compression ratio

[@RefrigerationMentor]

there are some rule of thumbs but not real standards alway go into the operation envelop or performance chart to make sure you stay inside. Low temp compressors will run at a higher compression ratio

[@randomrefrigeration4564]

What’s the high end of superheat that’s acceptable to Copeland If my memory serves me you said 20-40 is acceptable. 40 being the max as long as the discharge is not above 225 deg Please if you see this comment let me know so I know I am telling the junior techs right Thanks

[@RefrigerationMentor]

Yes if you can maintain a 20F (11K) superheat at the compressor and the discharge below 225F (107C) you should be good.

[@hassenabdoolwahid5292]

Hi, if I convert °F to °C, will it still be °C/1.8?

Dommage je comprends pas l'anglais

[@RefrigerationMentor]

Yeah it’s good.

[@jordanhenshaw]

What’s the point of converting to absolute from gauge? My high school maths is telling me this cannot affect the ratio when added to both sides.

[@RefrigerationMentor]

That’s a great question. I will look into that.

[@jordanhenshaw]

@@RefrigerationMentor Oh I already figured this out. It's because when you add/subtract the same number to the top and bottom of a fraction, you can't just cancel them out like you can if you multiply top and bottom by the same number. So 1/2 is .5, but if you add 14.7 to both top and bottom, you get 15.7/16.7, which is most certainly not .5. But if you multiplied 1/2 by 14.7, both the top and bottom, you get 14.7/29.4, which is still .5, so you can cancel it out. DIfference between absolute and gauge is addition, not multiplication, so you can't cancel it out, which is why that extra 15 or 14.7 is important for compression ratio.
