  • That was informative. Thanks for work.

    

  • very well done my friend

  • your great man,get more videos up,and maybe some hand on videos........ thanks georgia black

  • Great video, Do u have any videos with evacuation recovery and charging a/c units.

    Thanks

  • "please don't flood my email wit a bunch of that!"

    hahahahah

  • Great Great great u r Video is Great ,,, Thanks So MUCH for your Time ...

  • so the basic concept of using the compressor is to increase the temperature of the refrigerant coming from the evaporation coils to a temperature which very higher than the temperature of the surroundings,so that exchange of heat takes place....and similar for using a throttle valve so as to decrease its temp ,lesser than the temp of food materials inside a refrg????

  • my teacher sucks...ive learned more in ur video than my class...im in school for hvac now..please add more vids

  • i like how you touched on the super heat and the water referance it was helpful, i just started my refrigeration course and your videos are very helpful appreciate it.

  • I really like your videos. I watch hvac on you tube after work everyday trying to be the best I can at my trade. I am trying to further educate myself and was wondering if you do any on-line teaching?

  • I thought that was a brilliant and very practical explaination! I am interested to know if this is a similar or identical cycle in a freezer and what would be the significant differences in the cycle and apparatus for a freezer to reach the much lower temperatures....any chance of a video to explain this???

  • Absolutely the best explanation of the 'Refrigeration Cycle" its amazing how fluid you are in your delivery,, and in all your vids... but were the heck have you been,, pls post more vids,, thanks

  • Do I hear giggling at 5:35?

    Very helpful explanation btw, great job.

  • Excellant explanation well done i have understood this better now

  • thankyou. good video

  • I'm in college for hvac , this video is a great reference. My instructor even played it in class, thanks for this.

  • excellent job

  • im universally certified and been doing hvac for about 4 years and this is the clearest way to explain the refer cycle ive heard, haha

  • Great vids brother!

  • All 7 of your videos are great. Your presentation is the best part of clear, informative and useful teaching. Thank you. I want more. How about a lesson on charging procedures and desired high and low pressures.

  • this is very good but my teacher is also brilliant and i have learnt alot from him

  • This is brilliant. I am taking building systems for the ARE. Thank you so much.. I don't have money to afford such a comprehensive explanation.

  • What about the TXV??

  • Most excellent! Excellent diagram - so much easier to understand.

  • how come the refregerant is in liquid state at 115 degrres? and evaporates at 40 degrees? plus can you please tell me at what temperature it starts to evaporate and at what temperature it starts to condensate?

  • @pickacho4ever Because of the relationship between Pressure and temperature. If you increase pressure you also increase the boiling temperature. Because the refrigerant is on the high pressure side of the system the boiling point has increased.

    For your next question, Evaporation and condensation points depends on the refrigerant and the ambient temperature. Your refrigerant will boil quicker on a 95 degree than a 75.

  • @djslay34982 thanks alot that was helpful

  • @pickacho4ever You can find the evaporation temp and condensing temp by putting on you manifold gauges and taking the pressure of the system and converting it into a temp.

  • @pickacho4ever every refrigerant is differant and the reason the refrigerant is at liquid stte at 115 degrees is because there is more pressure is and the expansion valve lowers pressure so u can absorb more heat in the evaporator meaning the evaporation temp is lower

  • You are a very good teacher. I learned more from watching this than 7-8 hour courses i have taken so far. If you are offered a hvac course that lasts 15 weeks or less look elsewhere cause you really need 6 months or more to absorb all of this.

    We study two chapters a week. We review 10% of what we studied and do another two chapters. Go the longer schedule unless you have experience in the field.

  • Awesome, great information! Very descriptive

  • I have a career in software, not HVAC. I happened upon this video and I still found it fascinating. Thank you so much!

  • Good video,Yes Indeed.I wanna learn more,and more video from you is needed for the younger generation.please teacher more.

  • Beast I have ever heard on this subject.

  • Thanks

  • why is it that the Rankine Cycle is run with a liquid that has such a high heat of vaporization wouldn't u want to generate as much gas with as little heat as possible?

  • Thanks Bro,

    for breaking that down. I have been trying to understand that for the longest time, no thanks to those Hvac books I have been reading. Most of them don't make any sense when explaining Superheating and Subcooling. But you make it as clear as boiling water. Man you ought to write a hvac book. You could help a lot of people.

    Thanks again

    mrttea

  • He is most techer , teching clear and goo.

  • good job to say the least on your video ,,,how about if you want a class on thermostat wiring starting from the transformer i am not clear on that blue wire some say c for cool and c for common b for blue and on and on ,,thanks from denis in florida

  • Great job, Keep up the Good work!!!

  • gr8 video mate,,, just one question,,, r u talking in degree fereheit or degree celcius?

  • He is talking farenheit

  • YOU ARE BETTER THAN MY JACK ASS TEACHER!!

    thanks a lot!!

  • awesome video! things are much more clear now

  • thanks for the lessons very kind of you to take the time.

    You are a great explainer

  • Good job!

  • do you have any videos for charging by superheat and subcooling? Or videos on charging , evacs and recycling?

  • Great Video, I'm a new student in HVAC and I found this to be very helpful! Thanks

  • this is great stuff .... thanks for sharing your knowledge :O)

  • Thank for good instructional videos. Very simple and easy explanations. You rock man.

  • Your videos rock the dump, Bro!!! Best technical explanations, bar none. You break it down to the most basic terms and make it easy to absorb. I hope you post more instructional stuff for the youngsters in the trade.

  • I will post more videos to "rock the dump" :-) Thanks!!

  • yes my men we weiting for more colest videos hv very profesional ,thankyuo

  • I understand the process better now, thanks. I like the advice you gave, "don't just be a parts changer......be the best you can !!" I was going to school for electrical but changed over to hvac. I am learning alot from your videos. I kind of get an attitude when I go to school and can't get quality instruction like I can from youtube.

    Looking forward to more great videos !

  • I hope I can explain it the way you do some day ! it is the best I've seen ! where do you teach at ? and please post more for us acorns !!!

  • I teach in south Louisiana. More videos to come.

  • Hey man I just recieved my Associates Degree from Vatterott College in Memphis,TN and I was wondering whats the best way I can get better at troubleshooting because I'm only good at installing.

  • I would find my nearest trade school and sign up.

  • @William82oct get into a service job..thats the only way you will learn to troubleshoot effectively..oh and make mistakes

  • best way to learn troubleshooting is just to do it often and it will come natural, remember KISS (keep it simple stupid) always check power first etc, easy stuff, then youll learn your controls more etc, just learn what everything does in your units

  • Very clear explaination. Love it! Keep up the good work!

  • Sorry for the delay. I am currently working on new videos. Good luck on you career in th HVAC field. Dont just be a parts changer.....be the best you can!!

  • where you been  21 ive waited keep up the good video im looking for work now i just finished school in june
