    I call this a refresher course for an old dog. Never too old to review the basics. Keep up the good work.

    Finally I understand the importance of vacuum a system, and not let air go inn the lines and why is important to clean your lines when you gage up.

    I am attending an online course for HVAC, I dont have no instructor just a guide to follow that include me reading the textbook and taking quizzes. It was very frustrating to me and discouraging. I got so discouraged I took months off from finishing the course. One day I was on youtube and stumbled upon Ty's chanel and man you have helped me get a better understanding of HVAC. I am back on my schooling with a better understanding and an huge interest in this from the expamles to how thorough you are I feel like I can actually pass my course. I thank you so much just wanted you to know you have helped me and chnaged my attitude for teh better keep going with these videos.

      exactly the same situation im in right now, teaching myself has been pretty rough, but when I couple his videos with my courses, its like I actually have a teacher and examples to pull from. Im so grateful for this man!

    Very informative and interesting video I saw it three times and in every time I find something is new information I’m really appreciate you’re sharing acknowledgment with people.Q: When made a vacuum in chamber the temperature will go down and how much? Thanks you again.💐

      Io have not checked the air temperature yet. That's a good thought.
      The water boiling will eventually cool enough to mach the saturated Temperature Pressure and stop at that point. Somewhere I have a T/p chart for water

    Loving this series and learning a lot! But the audio seems to be out of sync with the picture throughout many of the videos, which makes it a little hard to watch. Particularly hard on this one, where we’re listening to the effects on the sound inside the vacuum chamber, but the sound comes and goes out of sync with the vacuum.

      Thanks for the heads up I will see if I can fix it.

    How can someone dislike this? Btw I did the same thing (inspired by you) by putting a balloon in a chamber under vacuum. My new in training co workers were amazed.

      Because they are Haters and can't see someone like Ty offers for free his Massive practical knowledge that is going to take people years reading Abstracts and still not comprehending anything, they just like to make stupid and no based dislike or comments. These Negative people are narrow minded best answer just ignore.
      Keep up great work Man. 👍

    Excellent video! I have another question for you if you're willing. Should I use different gauge sets for different refrigerants. I work on mostly R22 and R 410a systems. Should I have two different gauge sets or can I use the same ones with both refrigerants?

    • @love2hvac

      Same is fine but clean them ocationally. I use rx11 flush

    If let the vacuum pump running for long time the ballon will explode or what’s happen? Thank you.

    • @love2hvac
      @love2hvac  3 роки тому +1

      Great question. Its unlikely especially since my seals are bad and it dosen't hold a vacuum like it once did. If I had a larger chamber and I had put a little more pressure in the balloon to start, its possible.

  • @livingthelife2wice
    @livingthelife2wice Рік тому

    Quick guestion, is the gas expanding and compressing in the balloon while the vacuum is increased or decreased?

    • @love2hvac
      @love2hvac  Рік тому

      When the vacuum increases the pressure outside the balloon drops.
      The pressure difference from inside to outside increases so the elastic of the balloon stretches. The larger volume inside the balloon causes the pressure in the balloon to drop. This allows the existing gas inside the balloon to expand.
      When the vacuum is broken and air is allowed to enter the chamber. The increased pressure outside the balloon is greater and pressed against the balloon. The elastic of the balloon shrinks down causing the volume inside the balloon to decrease pushing the molecules closer together increasing the pressure in the balloon.

    The video is more than a second delayed vs the audio. Does anyone else have that issue?

    It maybe hard selling a vacuum if you called it a pressure transfer machine?🤔
