Dry Bulb, Wet Bulb, Relative Humidity Simply Explained
HTML-код
- Опубликовано: 18 ноя 2024
- An easy and simple explanation of what dry bulb, wet bulb, relative humidity percentage, and dew point are and where to take these measurements in HVAC applications. For adding refrigerant, you will mainly only need condenser air dry bulb temperature and the indoor wet bulb temperature. I go over where to take both of these measurements in the video.

Thanks Jay, just keep making these educational videos and we’ll keep watching them. You’re a top notch teacher.
Thank you sir! I appreciate that. 🙏🙂
This is by far the best site on youtube for fixing a furnace. I'm replying here because it's your most recent post.
Just fixed my high efficiency furnace watching a video you made 4yrs ago --- thank you.
You should be a teacher. You explain things well.
Thank you! I'm happy to hear that you were able to get the furnace fixed! I appreciate you taking the time to leave a comment and doing so on a recent video to make sure I see it. May your furnace run problem-free for at least 10 years now! Have a marvelous rest of the week!!
Great video man I’m starting my first job on Monday
Thank you! That's great bro!! I wish you much success and fast learning on your career. The first job is usually a little rough for the first year but you also learn A LOT. God bless you on your path!
The best of the bunch for us DYIers IMHO:
Logging: Nor Cal Timber Faller with Dan Leeper
Automotive: ChrisFix and Eric the Car Guy
Small Engine and power equipment: DonyBoy73 with Donny and help
Furnaces, water heaters, and most every appliance: Jay over at Word of Advice TV
What makes these folks stand out from the rest? their knowledge, their communication skills, and they don't spend a lot of time self-promoting or doing goofy stuff to keep ya' watchin'. They patiently explain everything so nothing is missed. There are lottsa' good folks out there, and these really stand out.
jay's always making learning simple, Great video
Thank you! 🙂
Love from Bangladesh
Hey jay I've always been confused about dry bulb,wet bulb but thanks for making it easy to understand....btw dewpoint is really high over there...must be really uncomfortable 🥵
I hope the video helped clear up some of the confusion and not just add to it. 😄 And actually it's pretty comfortable here right now. It gets a little worse around August but still, I think the climate in Hawaii is great year round. 👍👍👍
thanks, this always confused me in the past!
I honestly would’ve learned more getting just the codebook/modules and studying off RUclips than taking a college hvac program.
I agree. People basically pay the colleges to force them to learn. They implement deadlines, do tests, assign homework, etc. Unfortunately the majority of people don't have enough self-discipline to do it themselves. Most of the information they teach is available for free or just for the fee of a few text books. Especially with the abundance of RUclips videos nowadays, it makes it even easier to self-educate.
People who come from school never know a thing
@@robertpalmatier2699 It was partially my fault tbh, I didn't try as hard in school. But a lot of the classes I felt were just useless and unneccesary. Then when covid hit and all my classes moved to online learning I just quit all out at that point.
@@robertpalmatier2699we had a chick get hired into industrial HVAC after school. Didn’t even know what thermostat wire goes to each component.
@@WordofAdviceTVAlso the distraction of school and commute.
Good teacher !!!
Jay ,
You might wanna start another youtube channel with a catchy name for HVAC . Not saying your current name is bad but a lot of "new" techs coming into the field can learn this basic stuff to help them. Making sure they get to the right people will only help. The info in your videos would have helped me tremendously when i was a green tech in the field. The basics are so important to be able to advance to become a well rounded tech and understanding why things do what they do . Great info and great videos. Keep them coming 😉👍
Excellent vid Jay and ''I'' was behind you all the way on that alphabet question ... As for unemployed workers , they just stand idly by Aloha my friend ...
Haha thank you Eddy! I always appreciate your presence in the comments. 😄😄 Have a wonderful rest of the weekend my friend, may God bless you and yours!!
salute to you sir... thank you for sharing your knowledge... god bless and always keep safe ❤❤❤
Brilliant! Thanks Jay
Great content, sir! Thanks for the nice explanation
You're welcome! Glad you liked the video!
Thank you very much jay for your time and for your videos 👍✌️☝🏻
Well done!
Thanks...I learned something...
Glad to hear it! Thanks for stopping by!
Wet bulb is also super important in the winter if you are close to a rain snow line. Evaporative cooling can be the difference between snow, ice, or plain rain.
Yes! Thank you for mentioning that.
Excellent!
You might consider explaining ENTERING and EXITING wet bub VS dry bulb and how they relate to HVAC system capacity. These reading are required to process most utility rebates for new HVAC system installations.
I had no idea about wet bulb and dry bulb. Now I do, and I can do this, depending on the price of a psychrometer. Plus, I learned a little piece of history. Glad I won't have to swing anything around. I always stay around for the jokes - love them! Thank you Jay! Have a great weekend!
Is there a "best" or at least a "good" affordable brand?
Glad I could teach you something new this time! Thank you for stopping by and even staying for the dad jokes. 😄😎 May you have a fabulous weekend as well!! As far as I know, this is a good and much lower priced alternative to the one I have. It also has all the same features/modes: amzn.to/41daQpS
@@WordofAdviceTV Thank you for taking the time to find and recommend a lower priced alternative. I have a tight budget!
Good tips Jay. What’s a fair price to pay for a psychrometer , used is ok
LOL! "I have some jokes about unemployed people, but none of them seem to work".. Thanks for the informative vid!
Nice place 👍🙂
Thank you! We are renting and love where we are at. 👍👍
Hi Jay! Unrelated to wet/dry bulb: Years ago I threw away my dishwasher (which worked fine), and never got another one. This was due to a very loud water hammer that I thought would break solder joints in my house. I asked the plumber who installed the original dishwasher, but I'm not so sure he was really a plumber. Useless. Since then I've learned a bit about water hammer, and recently heard of a device called a water hammer arrester. Are you familiar? Any chance of a video about these devices? Thank you very much!
Aloha! Glad to hear you have learned a lot about the water hammer over the years. I actually don't do much plumbing jobs so I would be a bad person to ask about this. I have never installed one of those before. 🤷♂️
@@WordofAdviceTV I appreciate your answer. I asked, because even though you are specialist in HVAC, I would trust your word implicitly on many topics. It is the way you present things, the way you investigate, they way you reason. When you speak on topics, it's obvious that you understand the science, the inner workings, of the things you talk about. You exude professionalism, and you care about teaching others so that they understand and have the best chance of success with a project or dealing with contractors. I thank you very much for all of that. You may not be an electrician, but you did that excellent video on switches. You may not do much plumbing, but any plumbing topic you chose to present, I would have complete confidence in your ability and advice. Looking forward to you next video! Mahalo!
uh ive heard from other profesionals that you should be taking your wet bulb like within a feet or so of the evaparotor coil aka return duct by drilling a tiny hole and sticking a probe in. is it still accurate reading if its done from a far away grill?
Awesome 👏 👍👍
Thank you Harry!! God bless you my friend!
So I always wondered when u were in Minnesota what did u do in the winter for work
There were many furnaces to fix. 😄
@@WordofAdviceTV so there is work in the winter I’m getting into hvac Im going to Hennepin. An last question is Hennepin a good school? Because I watched some of your videos an u said don’t go to a expensive college for hvac.
@@acesoys5980 I went to Hennepin in Eden Prarie and it was great!! No complaints. Before we moved to Hawaii I worked for a gas company which guaranteed 40 hours a week. But they also had us fixing appliances, not just HVAC. Once you learn the trade, you will see that there are many options. Your skillset will be in high demand. So if a job isn't to your liking, don't hesitate to look for better jobs.
Hello I had a question can you just use a temp sensor or a thermometer instead of using a psychrometer if u don’t have one to measure superheat ?
Great video . How’s the hvac business in Hawaii
Thank you! HVAC business is good here and plenty of opportunities but I'm only doing this part time now and doing more online work that is not really HVAC related.
did you move to florida bro?
We moved to Hawaii 🙂
Are you located in California or Florida?
Huge Like for joke in the end of video ! -)
Me too 😁
How can I get it please
Amprobe Psychrometer: amzn.to/3MPg5Yn
I really like that shirt 👕 😍 good buddy I went back and tried spelling out my address and it kept deleting my message I don't understand why I had some friends in Iowa that put their number in a message to me and they text me sometimes to check on me and I have talked to them some they have a car channel and restore old cars. I hope all is well with you and your family Jay is there anyway you can get back in to Instagram? I found some dragon fruit other day and tried it but I've yet to find any star fruit so far..well Jay you take it easy buddy and don't get to hot out working I don't know how hot it gets down there I will have to Google it. Lol. It's been very nice weather here today but I haven't accomplished anything my arthritis has flared up and haven't been feeling good tbh also having some breathing problems well my number one good buddy best buddy I'm glad to see you my young friend and tell everyone that I said hello and give them all a big hug 🫂 for me and take care buddy and remember I love you all and God loves ❤️ you too .
Aloha my friend! Yeah, I don't think it will allow you to leave your address in the comments. Those messages seem to get ghosted. All is well with the family! God is good. Glad to hear you got to experience a dragon fruit! It's kind of like a non-sour kiwi. 😄 By the way, there are also different kinds/colors of dragon fruit too. (white, yellow, pink) Instead of dealing with Instagram, why not try emailing me again instead? I know you've mentioned that the emails weren't going through in the past but maybe things changed. My channel email is: wordofadvicetv@gmail.com I don't check it every day but I do check it regularly. I can get you a couple of the shirts you enjoy if you email me the size you wear along with where you want them shipped. Sorry to hear that the arthritis is flaring up again for you, along with the additional breathing problems. I pray that you will have relief and will feel better in a speedy fashion! Stay as healthy as you can and get enough sleep. God bless you as well!! The Lord loves you more than any human ever can. I appreciate the hugs and love sent our way, aloha from Hawaii!! (it rarely goes over 90F here. Pretty nice year round.)
@@WordofAdviceTV ok I will try it again I tried it before but you said you never got it I guess you don't have Instagram anymore or can't get back into it or something so I will try it again it's still in my contacts your email I probably have to get someone 20 years younger than me to help me with it if I don't figure it out again
wow......thats not the NORTH country.
Hey is there a way I can get ahold of you like message you I'm having a problem with my Central heat and air in my apartment and wanted to see if you could possibly help me fix it can I contact you on Facebook or something.
