Great video I learned a lot thank you for making a video about carbone filter and activate carbone filter
❤
thank you very educative
very informative vedio thanks for providing this kind of information to us.
Good video hate the robot voice though…
Thanks for sharing 😊
This is great information
To think someone made this and thought to themselves , "Lets start off strong and deafen everyone with an obnoxious sound effect at the very beginning. Ohhh, this distracting animated hand drawing photos and text looks great. Then I'll just top it off with Microsoft Sam as the voice. Last but not least, I will choose the worst text color options for reading onto a blinding white background. Now I have done completely the opposite of the Web Content Accessibility Guidelines; it's Perfect!"
Normally, in centrifugal fans, air is sucked along the shaft and delivered radially. I have observed that in Split AC, the fan sucks and deliver Air Radially. How? Thax.
I THOUGHT THERE WAS AN EXPLOSION IN THE OUTSIDE CUZ OF INTRO
Line ( dome line) represents saturated liquid or saturated vapor? and everything within the dome is also saturated liquid or saturated vapor? And Left & right of the dome is sub cooled liquid and super heated vapor respectively? Please verify? Thank u
Pl give your contact detail to communicate you .
And in 5 years we get the next new refrigerant. All thanks to this monster called government.
Annoying robot voice. 👎
The halting nature of whatever is narrating this course is off putting and distracting. Would love to hear it by an actual human.
Thank you
Aoa.Very knowledgeable Explanation. Thanks
How many time taken from fully open to fully close in spring-return type?

loose the AI and get a real human!
Why is the table of thermodynamic properties of R32 refrigerant in saturated and superheated conditions not available?
nope!! Will not listen to a bot spouting strange grammar
so i'm seeing folks install these mini split systems ans coiling the access lines next to the outside unit .... is this a problem ?
Not for R-410a systems. It was a problem with the older R22 refrigerants.
To get total required louvre area i dont think it is Freaa area x 1.5 but x by 2 as the typical free area of a louvre is 50%. You have already calculated the free area so you simply double it.
Correct, factor of 2 as a lower limit. I've seen most louvers with 40% NFA. I typically would calculate for a factor of 2.5 to be safer.
You couldn't shell out for an actual voice over? This AI generated narration is truly awful.
One more Messi moment 😊
so nice
Thank you for your good information
Robotic voice is burtal to listen to ... worst explanation ever
so I measures outer diameter on my vernier at 43mm...Does this mean the pipe size is 1-14 inch?
Where is Carbon filters?
As liquid enters expansion valve, some flash gassing occurs to effectively cool the liquid down to evaporator saturation temperature. This flash gas does not contribute to evaporator cooling therefore is efficiency loss. Larger amount of subcooling is advantageous for this particular aspect, but ... Higher subcooling reduces condenser effective area for cooling refrigerant hot vapor which exchanges heat to air flow much better than cooled, condensed liquid refrigerant due to the greater temperature difference in condensing hot gas to air flow through condenser. Higher subcooling on output of condenser raises compressor discharge gas temperature/pressure and can increase load on compressor causing more compressor electrical consumption, which is an efficiency loss. Higher SEER units often accomplish their increased efficiency by using a larger condenser. Larger condenser usually holds more refrigerant so there is greater volume of liquid refrigerant margin allowing them to run at lower subcooling levels. Large condensers can cause problems with compressor input flooding in off mode due larger refrigerant system loads. Many systems with large condensers shut down expansion value when compressor is shut down and rely on compressor discharge check valve to trap liquid refrigerant between compressor check valve and shut off expansion valve. Once condenser cools down in off mode, most of liquid will stay in condenser during off mode even when there is some leaking of check valve and shut down expansion valve. This greatly reduces possible liquid flood back to compressor input during off mode by keeping most of liquid refrigerant in condenser during off mode.
Went by to fast useless info

Nice thank you
What is L & C ?
Many useful information collected in this video. Thanks for your kindly efforts and sharing learning info.
Perfect video on oil traps!
Thanks for taking time to do this
Highly educational.
is it possible to pay you to help me tocalculate the free area of my louvered door
👍👍👍
The wiggling hand is annoying and distracting.
Thank you for this informative video ❤
En español sería bueno traducirlo
My 1 ton bluestar split has issue like blower is not throwing complete air it stuck in some places. Air flow comes with whzzzz whzzzz sound. I can fell the chillness and cooling. But air out flow from blower stuck in one side. My Ac mechanic told the same u trap. Is the u trap recommended for my issue. I changed outdoor eveporator coil my blower fan is good no issues, I did full water service gas level is also good.
Terrible video!
Great work ❤❤❤
Nice presentation except the hand jive thing . Very distracting .
We dont use 45° fittings in refrigeration. Also inverted p traps are usually installed at top of riser.
Thanks for extraordinary explanation.
