Hi, I hope you can read this. But how did you get a 21deg F from given 11.8 Deg C. Because if you are going to convert 11.8deg C it should be 53.24deg F.
Hello sir, this video was very helpful so I have a question, why the heat load through the floor was not calculated? the same question for the heat load through partitions between zoon 5 and the other adjacent zoons .
The computed automatic cooling system complex for big or large buildings by placing temperature sensors everywhere.. This is what calls for the possibility of studying air engineering circuits
I'm still trying to figure out how is 225/1000 x 5 = 2 at 16:37 I'm definitely not getting that answer. Is this an error? Also where did the 3.4 btu/hr/watt come from at 18:08?
is it logic to get CLTD corrected = CLTD - 13.5 (because i have minus here later on in my calculation the Q is negative) is it correct or is this wrong?
I am in doubt too. Type C3 >> R = 0,125 m2 k / W. It was suggested 0,88 m2 k / W (0,2 Btu / h ft2 °F. Maybe C13 (150mm High Density Concrete R=0,88 m2 K / W) could fix the numbers.
Hello, your videos are very helpful. I have a question, instead of using the temperature of radiation from the sun, is it possible to apply the temperature from the fire if there is fire ?
Hi, thanks for the video. I have a question, for the roof, if we look at the R value, the higher it gets, the associated number in table 30 goes up wish means higher Cltd values. Whats bugs me, is the fact that with more insulation, we have more cooling load to deal with, but it seems counter intuitive. I would expect better insulation to mean less cooling. Am i missing something ?
@@AMJEngineering i was refering to 8:09 with Roof no. In table 30 and R values in table 31. Additionaly, what does mass location mean ? And are the R values in table 31 for the complete roof composition, because even 5.3 seems low for a northern country. If i have an R = 6.5 whats do i pick in table 31 ?
Thanks for sharing your knowledge. It was well discussed and easy to understand. Can you please share the CLTDs for different latitudes? Thank you.
Thank you for content, it helps my career path a lot
Thanks for feedback
good calculation, brother. helps alot.
Thanks
Thanks for the vids. However, where and how did you get the CLTD correction for latitude and months?

Hi sir, thanks for your video.
I have a question, regarding the factor of LED light, how many factors for it?
Thank you so much for this video. Could you please send me the ASHRAE table referenced at 10:14? Thank you!
Hello sir, this video was very helpful so I have a question, why the heat load through the floor was not calculated?
the same question for the heat load through partitions between zoon 5 and the other adjacent zoons .
Also take us through hvac ductwork design procedures
Will do
thnk you for excelant work simply how do i get all table pleas
Thank you very much for this video.
Keep up the good work 👏
Thanks for valuable feedback. Every share helps me keep going👍🌹
How can I get CLTD value for 75mm sandwich Panel material -2 Deg Latitudes. I can't find it in the existing tables.
Hey @AMJ,,, can I get a listing of the Tables??
The ones not in ASHRAE Handbook
The computed automatic cooling system complex for big or large buildings by placing temperature sensors everywhere.. This is what calls for the possibility of studying air engineering circuits
I have the 1997 ASHRAE Fundamentals Handbook, for Laredo Area, Table 1A is on page 26.18, and Table 1B is on page 26.19. Is there an error?. Thanks

Also where did the 3.4 btu/hr/watt come from at 18:08?
what would you do if your wall doesnt match one of the given wall types?
is it logic to get CLTD corrected = CLTD - 13.5 (because i have minus here later on in my calculation the Q is negative) is it correct or is this wrong?
What do I do if my wall code number in table 11 is not in the table 33A?
Kindly Can you provide all tables for 36 degree
just want to clarify where did you get the 0.2 U-value for the wall..Thanks
This should be given for any type of wall.
I am in doubt too. Type C3 >> R = 0,125 m2 k / W. It was suggested 0,88 m2 k / W (0,2 Btu / h ft2 °F. Maybe C13 (150mm High Density Concrete R=0,88 m2 K / W) could fix the numbers.
How to convert it@@joao_cavalcanti
correction
11.48> Degree centigrade multiply by 1.8 and add 32 to get Fahrenheit
Yes you are right and thanks for your comment. I mentioned that I made this mistake in previous comments

At timestep 18:54 ; from where this space load comes?
How can I get the ASHRAE value for UK
Thanks for the video... It's was great for me.. Could you please send me the tables?
Hi sir. May I know that how to get the Q(total) value at 18:29 table?
8:42 Please where did you get this table from? Cannot find it in ASHRAE 1997 handbook
Did you find it?
@@gwv8647 No. didn't find it
How can I calculate correctly U factor?
Its just that Ashrae has a lot of tables for U values and I'm confused
Depends on wall and roof types. Choose the nearest ashrea composition
Where you get u value from?
ashrae book
can you provide me the ashrae 1997 fundamental book?
How to convert : w/m^2k to btu/hr-ft^2 -°f?
Sir, please share ASHRE latest code

please let me know the video timing you are referring to.

Good day po, can i have a copy of solar cooling load for 8deg north latitude..ty
👍
please send me the book if passible
