Refrigeration Cycle Tutorial: Step by Step, Detailed and Concise!

Refrigeration Cycle Tutorial: Step by Step, Detailed and Concise!

By Martin KingPosted



In this HVAC Video, I give a Tutorial to Explain the Refrigeration Cycle with Superheat and Subcooling Step by Step, Detailed and Concise! I go over how the Basic Refrigeration Cycle works from where the refrigerant enters the vapor compressor as it goes completely through the system, what the saturated state is, what superheat, total superheat, and subcooling are, as well as other detailed comments as we go through the system.

  2. Abdullah Uthman

    Thank you buddy, this video helps
    I just started an HVACR course and there is so much information to learn , it’s a 16 week condensed course 1 day a week that literally flies through everything and it’s difficult to absorb all of it and process things fast enough to know what to do same day with zero prior experience…

  3. Den P

    Awesome

  4. Steven Valle

    Wouldn't the condenser fan motor be sucking air through the condenser, not blowing it out. Usually I put a piece of paper on the condenser to see what the fan is on, when it's on it should stick.

  5. Justin Belleville

    What would this diagram look if the system was either over or under changed?

  6. JWil2triLLL

    Started out doin simple things like home maintenance then moved to fence and beach home framing. Today i start learning this. as i recieved a invitation in sc with my cousin so im tryin to cram as much basic info as possible so i learn quickly. Thanks for the video

  7. Aj

    Thank you much!!! Very helpful

  8. Francisco Ramos

    Yes I was funny wrong heat in gargre

  9. Ashroyer86

    How much of a pressure change coming out of the condenser? Since heat corresponds to temp.

  10. MajorKee

    Am I the only one who gets bothered by the fact that subcool is in red and super heat is in blue. I know that’s how the hoses are set up on the gauges but that always gets me a bit confused

  11. Jonathan Carbajal

    What a great video!!! Thanks for explaining 🙏🏻

  12. Rene Cuevas

    Nice presentation

  13. Rene Cuevas

    Need more Volume pls tnks

  14. Rene Cuevas

    Been a svc tech 30 yrs and still watch this video to keep up with the basics to teach the newbies on the Trade

  16. Johnny Parterlee

    Thanks a ton, was asked this question for a job interview. now I know!

  17. Victor Correa

    thank you so much for this, its helped me understand refrigeration cycle in full. I was having trouble fully understanding some points in class and this video along with your superheat/subcool have cleared those issues up for me. subscribing to your channel for sure!

  18. Cortlandt Att

    Awesome how you explain.
    Thank you

  19. Jesse S

    Great explanation.

    Why do I always hear “the heat is dumped outside,”” (at the condensing coil). Indicating that the heat you feel from the outdoor unit is from inside the building?

  20. legendslayer 289

    Cooga shaca cooga Shaka oh nothing just resurrecting my WiFi router so I can learn this

  21. Broshugan

    91C US Army, thanks for the help!

  22. Jake Hojnowski

    Why is it called superheat when it's coldest and subcool at its highest?

  23. Mister Revealator

    I just started in the field. This video was extremely helpful! Thank you!

  24. elkvis

    Saturated state, where gas and liquid exist at the same time, sounds an awful lot like the definition of a supercritical fluid.

  25. Meximon

    Sigh, yet another guy who manages to better explain in 4min what my prof couldn't in 2h of lecture.

  26. Lester

    Yes

  27. Bob Parks

    You are incorrect

  28. Flyboy 0711

    HI @AC Service Tech LLC What happens if the airduct is partially blocked? Is seems to produce a higher temperature output. Any clues?

  29. unnamed

    Been a service tech for 10 years and still watched this video to keep myself sharp and to the basics

  30. Cody Smith

    I keep seeing things about an oil seperator what is that and what does it do

  31. Chris Boughton

    I swear I learned more from watching these videos than I did from going to college

  32. Po

    Great video thank you

  33. Matthew James

    Anyone here from Technology Connections?

  34. Japer Electronics

    Are their rule of thumbs for ideal condenser, evaporator, discharge and suction temperatures? Would their be a point where increasing evap airflow causes temperature to increase too much? Would their be a point where increasing condenser airflow decreases the gas temp be too low?

  36. Francisco Bedregal

    Great video man this is all I do after class just learn and get info! thank you! 🙏

  38. no limit_

    Man thank you best explanation by far !!!

  39. Patricia Wynkoop

    Absolutley Awesome ive watched this 10+ times can you please do one on a gas furnace. startingg from checking the draft induced motor and going over each step and part all the way too the blower?

  40. Frank James

    i appreciate that you have a video on the subject yet you are able to explain it clear and proper.. this is another good skill you possess

  41. Waafa

    So much better then Bryan Orr. You're easier to understand and go slower.

  42. Julian D

    when you come home after class and learn on youtube…great short lesson…Thanks!

  43. التميمي

    Why does the pressure did not get down just after the condenser?

  44. Alex Binder

    am i retarded if i have to watch multiple times to understand/remember?

  45. Israel Mireles

    This makes so much sense thanks
