    I literally jumped when that compressor in animation, exploded 🤣
  • @landolorean51
    This channel is amazing, the detail that goes into your animations as you describe these processes is a true gem of a study aid, I am a studying hvac apprentice and I'll be using this material to get this stuff down cold!
  • @joseojeda4397
    Recently got into the commercial refrigeration trade. Been watching your videos since I started. I appreciate all the info really helpful
  • @eaf2k
    Wow, absolutely high quality stuff. The level of details, clear narrative and even background music... Good job and tons of thanks!
  • @yechris2001
    I have watched videos from dedicated hvac techs and I was still confused. You explained it perfectly. Thank you
  • @bala14321
    Very well explained and highly informative. Compressor damage/ explosion due to liquid entry is worth the highlight.
  • @xiaomingzou8110
    This is a great video for understanding the importance of TXV and its working principle.
  • @jpjpjp5847
    Great simple video explaining the process for someone who is not an HVAC tech. Thanks.
  • @richsellskc
    nice. i was dozing off near the end of the vid....suddenly "BOOM"... good one!
  • @buttonman6262
    Got my SV Second Engineer oral exam next month and these videos are a godsend! Thank you!
  • This is the best video I’ve seen explaining the TXV. Thank you 👍🏼
  • @ginodimarco1153
    This is a wonderful exploration a relatively complicated subject. I am currently replacing a compressor and txv for a home owner. This is a fantastic video to share with him while I complete the repair. Thank you .
  • Great discussion on the function of the bulb...its pretty clear that if the valve gets stuck in the closed position, there will be no cooling even though the refrigerant in the bulb is expanding against the diaphragm (trying to open the valve).
  • @maysaraabdo5339
    Well said you really summed up the entire information from the beginning of your video in your example. Thank you.
  • Superb! Very helpful for people like me who are venturing out into this field: ie- Marine engineering. Will you please do one on steering system
  • Thank you very much.You made a very clear explanation about refrigeration system
