Thanks a lot , your lectures are really helpful. would you please provide a copy or a link for the Psychrometric variables and symbols doc. , or for the wiki.Merci beaucoup.

Thanks mam, love from india, i was looking topic of humidifaction with specfic details about psychometric ratio, lewis no , humid heat and the formula relating temp in - sat temp , if u active in channel could u tell ne

hi..i have a question in different subject if you can help in evaporative cooling...is it useful to decrease the temp of water spry or water washer ex: if out air 36c,60%rh..on psy with 90% evaporative efficiency.h ll get a 28c db and 90%rh.. so if i enter a 7c cold water to the washer .will i get a cold air temp....with knowing that in 100%humidity the db is about 27c thanks

we all know u r copying from book but u should at least read them

Nicely Explained Professor.

Nice explanation thank U

thankyou madam.....

Hi, I am from Mongolia and also HVAC engineer too. Could you leave your email or any contact? if is it possible

Help me in HVAC?

Thank you for this Dr. Angela :)

Good day Mam, Your lectures helped me a lot. Just want to say Thankyou. Are you on linkedIn? or any professional social network?

Please explain to ton of refrigration mam please

Thanks mam

of hatunda erik gibi kütür kütür

Teacher Im thankfully with your job and aI apreciate it a lot. I´d lñike to know where i can find de guide you use for it? thanks a lot for teaching us and share your knowlage!!!

Just exclent . Subscribed

I am already understaned Thanks

Wtf hahahaha what are the odds to find your assignment being answered online. Lol

Hi if we have SHF negative how we calculate q total

Woah !!!! Thats unfair ...i ve seen your both part lecture just to find out the calculation for winter heating kw and equipment selection . But u did explain every other things except winter heating load....

I am from India

Hello mam

Hi

Why SHE is so important to HEATLOAD

Try to solve the numerical on angle made by beam radiation with normal to flat collector ..it is very important according to our syllabus ...we can also read theory from book..but unable to solve the problem

Thank you!!!

Try to solve the problems because exam point of view this is important topic

please do more videos on GREEN BUILDING COUNCIL REQUIREMENTS,LOAD CALCS ETC

where can I found the first, second, third and fourth lecture? And thank you for the lecture

you find HF of steam at 212 degree F at 1150.5 btu / lb this becomes delta h / delta w ratio of energy to moisture use the protractor it lines up to 0.09 SHF more or less use that slope

Gd

Hi Angela thank for the great videos. I enjoyed watching them. What's your reference book please ?

I was looking forward to the questions

Hi but how do we find the sensible heat factor please reply tq.

what is the name of the book please

very helpful

Thanks for crystal clear clarification. I thought i had to learn steps now i'm feeling lighter. Thank you.

not soo boring like lectures at our school

Yes, what book are you referring to in the lecture?

Where did you fixed camera.. it's really good setup ..

Hello, doctor do you have video's for cooling load calculations?

Thank you for each efforts

thanks

Mam,there is a mistake at 8:30 min.you wrote mw=ma(w2-w1).but later you wrote correctly

Amazing clarity in explanation, Professor ! I really enjoyed the discussion. I am a student in the IAC program and that's how I found this video.

Hello ma'am , it was an intereseting lecture, i want to learn refrigeration and air conditioning (as per your university syllabus for mechanical engineers), if you could upload it by giving a lecture number from basic to professional for our convenience , i will be glade, thanks

Can i calculated the sensible heat from this formula q=mCp(t2-t1). ??? When i calculated i found change in result maybe 6000 difference !!

You do not understand what you writedown. Where are the figures? You are a bad teacher

excuse me you are wrong here. R' is thermal resistance while R is unit thermal resisitance because it is divided by area A. You should correct this.

what are the books that you follow for your videos? books for Refrigeration, Thermodynamics, Renewable energy sources, etc????
