Thank you so much for the video. I have learned some very helpful stuff. Can you please show how to import a .jpg image into Sweet Home 3D? I have a picture I'd like to hang on the wall. TY
Thanks!
Hello, can you please tell me if you know why there are no metal-plastic windows in the US like in Germany? US windows mainly have an aluminum frame and one glass, the thermal conductivity coefficient of such windows is three times higher than that of metal-plastic ones.
Thanks for important information.

Hi, when calculating the air flow formula, do I need to use °F for your delta-T? Will the formula be diffrent when using °C for delta T.?
Yes, this formula will only work if the delta-T is in °F.
if I have a target ACH of 5, a garage size of 30x20x9, I get a CFM of 450... Living in Florida, I have aa deltaT of 30F... (target indoor temp 70F when outdoor is 100F) So 450 x 30 x 1.08 = 14,580; rounding up I need a 1.5Ton unit? (Mini Split, no duct work). CFM = 20 x 30 x 9 x 5 / 60 = 450. How's my math?
Thanks for watching! While air flow is certainly a useful too calculate BTUH, when sizing equipment the building itself needs to be taken into account. This is done by way of an ACCA Manual J load calculation. Factors like insulation values, building materials, building orientation, and weather data all come into account. How's this, shoot me an email with your contact and I'll let you know what info is needed and I can work up a Manual J for you and give you some equipment recommendations. kingenuitytech@gmail.com
@@KingenuityLLC wow, that's incredibly generous offer. I'll shoot you an email. Thank you.
Nothing comes up when I search for Surface text. It just says that "All items are already in the toolbar" and "No items match your search". But I don't have the little ST box that you do for surface text.
I figured out my issue. If you are already in a sketch, the + in a box does not show up. You have to leave the sketch function to access the "Add custom features" tool. Once you do that, the + in a box that was clicked on in the video is available and you can add the feature. Thankyou for the video Kingenuity. It was helpful.
@@saulekaravirs6585 Thank you for sharing the solution!!! I had the same issue and YOU helped ME! THANK YOU!
You rock, sir.
thanks for imp inform , next week i hve exams and i was very confused.. now i am clar.. after the eam i wil lsure remember your guide . thanks
Really good stairs tutorial. THANKS FOR SHARING.
Glad you found it helpful. Thanks for watching!
thanks
6:34 - “I’m a pepper, he’s a pepper, she’s a pepper. Wouldn’t you like to be a pepper, too?!” BTUs?! Shouldn’t this be called ATUs? Pint is American; kg is British!
I absolutely love this comment!
@@KingenuityLLC Thanks. I like to put just a little more thought into my comments than _many_ posters do (btw, I guess I’m showing my age with that jingle allusion.) I’ve only been in refrigeration for a couple of years, so I really appreciate your video. Now, I need to come up with a way to calculate the American Thermal Unit!
This was really helpful! Thanks!
Glad it was helpful. Thanks for watching!!
Speaking on the convince factor. I know it changes with the starting temperature. How does altitude affect it?
Great question. Altitude does come to play with a precise calculation. The 1.08 has become a "convenience" and is based on standard conditions (at sea level). For true calcs, air density at the blower is needed. Here is a handy PDF from Rupp Air with the formula to account for air density. www.ruppair.com/documents/white-papers/Actual%20Air%20Density%20BTU%20Calculation.pdf
Great video....even better when its what youre searching for on YT !
As rcinfla9017, the fudge factor is based on the density of air. Air density changes with altitude. The standard density of air at sea level at 68 degrees is 0.075 lbs/cu-ft. At Denver, the air density is about 85% of what it would be at sea level. Also, this "HVAC" calculation is for heating only. For cooling, not only are you trying to reduce the air temperature, but you also must account for a reduction in humity (or more specifically, the extraction of water that is water vapor in the air). You must pull heat energy out of water vapor to condense it into water. Just think of an ice maker in a rerfrigerator. The refrigerator pulls enough heat energy out of water to make it freeze. The total heat energy in air from the air temperatue itself and the heat energy of the water vapor has a fancy word for this: Enthalphy. To measure the change in both temperature and humidity, a change in enthalphy is needed. So a BTU calculation for cooling at "standard pressure" is 1.08*Cfm*(the change in enthalphy). A psychrometric chart will give you the enthalphy content of air at a wide range of temperatures and humidity levels.
Right on! Excellent comment, thank you!!
Thanks man, much appreciate you sharing this.
Thank you for demoing this, straightforward and clearly communicated. Made it very easy to follow and make my own!
Thanks for the feedback! Glad it worked out for you!
question how do you find the delta T? do you run the furnace and take the split temp between the supply and return duct? or do you go,by this being a constant split. I think i remember from school it was rule of thumb and it was 17 degree f and between 22 degree f. would have the same question for finding current cfm
You are correct, you would find the actual delta T by taking the difference of the return air and the supply air. A typical value that I have always used for a "typical system in ideal conditions" is 20 degrees F.
Can you demonstrate how to extrude remove curved surface text?
Sure thing! I'll add it to my upcoming list. Thank you for the request!
Thank you very much those❤
You're welcome 😊 Thanks for watching!
Very nice friendly, informative, helpful video.. Can't get much better than that! Thank you!.
Glad you enjoyed it! Thanks for the feedback!
does loading an external tool mean this can not be done on the iPad version?
I'm sorry, I am not familiar with the iPad version.
perfect . Thank you 🙂
You're welcome 😊 Thanks for the feedback!
Great

Thank you so much for sharing. Have a nice Christmas
Glad you liked it. Same to you!! :-)
How come the needed CFM increases with decreasing delta T?
Great question! It has to do with the delivery of energy. A lower delta T means that there is less heat transfer so you need more movement of that lower energy. Let’s say that we have to heat a volume of air in a room. To do that we have to add energy, in this case BTUH’s. If we added very hot air (therefore with a high Delta T) we don’t need to move the air as fast because the room will come up to temperature quickly because of all of the energy that we have at our disposal. Now if we take the same room and blow in air that is just a little bit warmer than the room air (low delta T), we don’t have as much energy to bring the room up to temperature so we need to move more of that air lower energy air to add up to the total energy that the room needs to keep temperature. Another way to think of this is with a bicycle. Let’s say that you want to ride your bike up a hill in 2 minutes exactly and there are two scenarios. The first scenario is that you have super strong legs (high delta T). The second scenario is that you skipped leg day (low delta T). Both require you to pedal at a certain speed to get up the hill in 2 minutes; pedal speed in RPM (CFM air flow). With super strong legs we can use a harder gear and pedal up the hill in two minutes using less RPM’s. With weaker legs we have to use an easier gear which will require us to pedal faster but with less applied force to make it up the hill in 2 minutes. Same hill, same time, different pedal speed based on the amount of strength (energy) that we have. More strength = slower pedal required. Less strength - faster pedal. Hope this helps. If not please let me know!
outstanding explanation @@KingenuityLLC
I cant see the lower level How to make the underlay visible?
When you are in your floorplan, take a look in the properties menu on the left. Scroll down in the property menu and you will see a section named "Underlay". From there you can change the "Range: Base Level" to the first floor. You will have to click on the Apply bottom on the bottom right of the menu for it to take effect.
Thank you for your clear explanation. Please make more videos.
Thanks so much! If there are any specific topics that you would like videos for, please let me know!

Thank you,the best tutorial
Thank you so much! Glad that you found it helpful!
The outer dimension measurements have somehow moved on my project. How do I return their placement back to the "out of the box" default placement?
On the left of your project, click on "Info". Then select "Draw Dimensions". From that menu you will see two toggles. One for "generate dimension lines" and the other for "generate outer lines". Ensure those are both turned on. Hope this helps!
Thank you
Thank you, very helpful! :)
1.08 fudge factor is density of air in lbs/cu-ft * specific heat of air * 60 minutes in hour. 0.075 lbs/cu-ft * 0.24 BTU/lb * 60 mins/hr. = 1.08. It is temperature and pressure dependent. Formula works for heating where there is not any phase change occurring. Air conditioning cooling has phase change (latent heat) of humidity in air, turned to condensed water which consumes some of the air conditioner's cooling btu's capacity. Direct electric heater input power is very near 100% efficiency on power transfer to air flow, where air conditioning cooling from evaporator has a lot of other factors impacting heat absorption by evaporator coil.
Thank you for explaining the factor. Just add F to specific heat units.😊
