Scroll Compressor Discharge Superheat

I explain my thoughts on scroll compressor discharge superheat. This is the difference between discharge line temperature and condenser saturation.

Thank you for sharing your knowledge

I can't tell you how valuable this is. Thank you so much and keep up the good work!

I share your content with all my techs
I appreciate the knowledge you share

In this field, heat concept is everywhere

[@Eighty8Fitter]

Anything over 225 degrees the oil starts to breakdown too. Good indication of failing valve plates on a recip

Did you have proper subcooling?! It’ll be interesting to know.

Awesome tech tip thanks

Trane RTHD uses discharge superheat as a very important value, you may know the term "heartbeat" well

Nice one

11:30pm
Mineral oil breaks down at 270’F
Internal valve plate temp is 100’F hotter than discharge
line
225’F line is = 325’F valve plate
THIS IS OVERTEMP for valve plate and motor winding and oil.
Check for line restriction
Check for poor condenser air flow
Check for rotted fins

Would compression ratio be another measurement to take ?

[@HVACTIME]

Compression ratio is worth notating depending on what your analyzing. Higher ratio will typically mean higher superheat.
