This is why I love TH-cam. I’m not an hvac tech but I’ve installed dryers before. I’m sitting in a drive thru looking at a condenser and there’s a rusty dryer next to it and I think, “you know I wonder how that works.” Two seconds later and I’m learning. Thanks!
I was promoted to the Maintenance department at a Cannabis production plant here, with next to no knowledge or understanding of HVAC/Electrical. Your videos have been incredible. Thank you so much man. I talk about your channel to everyone I know
Here from Danfoss United Cooling Live, how have I not found this channel before, excellent videos. A refresher on certain topics is always worth while. Education is key to continuous development.
Just subscribed due to VERY clear n understandable illustrations how a filter dryer works n internal components adds up make a clear sense. Well-done! Just find out Ur video! I will view many more of Ur excellent videos, as most people are visual learner is my underpinning point why Ur video is very helpful n should be viewed by hvac wanna be n just become hvac tech!
I have nothing to do with Hvac, but decide to watch every single of your videos just to know more . Sometimes i struggle a bit with no prior knowledge.
Excellent summary! Filter/dryers should be replaced anytime system has been evacuated for major repairs such as compressor replacement, leak repairs, TXV replacement.....
Was also wondering what's inside the airplane wall, as in how the ducts are made compact and efficient, and the ram air system. Like whole airplane refrigeration system layout in form of animation, cuz till now, I've been using my imagination. I read 3 types of Air plane refrigeration systems Simple, bootstrap evaporation type and Reduced ambient type. U don't have to cut anything tho :'D

when i was apprentice still had units with refillable driers they came apart unscrewed one end filter media was supplied in large can we used to replace because they were brass with a great scrap value. still got one i use for flushing systems
So am I safe to say that the filter dryer is a one time thing ? Brazed welded in and used once to clean all the crap and that's it. Because the line set is sealed no more contamination can get inside . So one time use ?
Good video. But at 1:33 you said "solder connections"... We don't solder any joint in refrigeration. It's a brazed joint... Much stronger and no acid contamination from paste.
So, is this whole device considered a consumable?? Doesn't seem like something that could be cleaned without destroying it... Though I guess the hope is that 99% of the time, it has very little to do, and it's mostly just when initially charging a system that there'll be some moisture and/or dirt?? Or... ?? Would be curious to understand more on that... though... I also see that the next video in this playlist is "How Filter Driers Work", so, perhaps I'm about to find out. :)
There are some you can get for acid burn outs in those situations that require major decontamination, but simply having it on the liquid line is is easier with the lower volume of flow of liquid and immediately helping the metering device from plugging up.
Why was the screen dirty on the wrong side of the direction flow? Seems like the filter would be capturing stuff on the core side not on the other side as yours was. Was that dirt and stuff from the cutting tool maybe?
Brazing vs. Soldering: 3.4.9 JOINT, BRAZED - A gastight joint obtained by the joining of metal parts with alloys which melt at temperatures higher than 800°F (427°C) but less than the melting temperatures of the joined parts. For high pressure refrigerant systems. 3.4.10 JOINT, MECHANICAL - A gastight joint obtained by the joining of metal parts through a positive holding mechanical construction. 3.4.11 JOINT, SOLDERED - A gastight joint obtained by the joining of metal parts with metallic mixtures or alloys which melt at temperatures not exceeding 800°F (427°C) and above 400°F (204°C). For low pressure hydronic systems. 3.4.12 JOINT, WELDED - A gastight joint obtained by the joining of metal parts in the plastic or molten state.
I've sometimes wondered, if dirt is getting into the refrigerant, wouldn't that imply an unclosed/leaking system? Perhaps there is a break in the suction line that is pulling in contaminants?
Because in the end, the liquid refrigeration is actually going to be getting its back pressure from the metering device (which is a very small opening and the liquid refrigerant is really not flowing that fast with a lot of volume on a standard residential system). Also, If you notice the size of the filter dryer, it's much larger than the liquid line it's serving. So with all the surface area for the refrigerant to pass around the entire outside circumference, this offsets any pressure drop through the fine filtering material and allows it to come out the end without issue.
I keep wishing it were possible to buy parts from hobby electronics suppliers to play with tiny arduino sized cooling systems. I want to play with peltier modules and miniature dc compressors to try and result in a unit that can charge a phone from room heat. (cooling the room in the process). !!! Any tips??
@@EngineeringMindset well, i ordered a couple of peltier cheapies and a tiny motor and compressor, but have no vision on what to do next. I dont know of heat exchangers smaller than pc cooling, and need to find more resources for inexpensive parts. In honesty, i wish it were like other projects, with a bunch of top videos from years ago, but as of yet I havent found any.
I don't really get it. Why do we need this? I mean if the system is installed precisely than during operation nothing can leak inside or outside. Or am I wrong?

Hi..am grateful seeing u for the first time from Lagos..Nigeria.💕💕 all i have been hearing was just your voice..bro..u r cute..😇😇
Excellent video. When should be they replaced? What is it's life?
Always wondered what's inside.
Thank you for this video.
Hopefully it's popular and we can cut some more stuff open!

As always, you made another precious video.
Its very good for technicians to understand hvac
Thank you bro your the real MVP with th diagrams
Thanks a lot for showing us how the filter is
Would it be possible/useful to see what a *used* one looks like?
Excellent presentation
Sir please give detailed information about VRF/VRV like you did for chiller. Thank you.

Finally we get to see Paul!
Please do a video on a refrigerant muffler that goes on discharge at the compressor. Sometimes guys will think it is a secondary dryer :))
Sometimes it is a filter drier
What a legend teach
Supreme content, very usefull. Please make video: What's inside a Oil Sparator - How it works. I will send you a coffee. Thanks
when i was apprentice still had units with refillable driers they came apart unscrewed one end filter media was supplied in large can
we used to replace because they were brass with a great scrap value. still got one i use for flushing systems
Thanks for sharing knowledge .
Great video!
Please make a video to explain transmitter and receiver
Is this filter cleaned on a regular basis or is the whole component changed periodically ?
what is the allowable temp drop across a filter drier?
and what shoud it be when used for the first time on a new system?
Wow you grow so fast ..
last time i subscribed you just have 10k
Very nice Good job Sir
So am I safe to say that the filter dryer is a one time thing ? Brazed welded in and used once to clean all the crap and that's it. Because the line set is sealed no more contamination can get inside . So one time use ?
Why is this listed under VRF training??🤔
Good video. But at 1:33 you said "solder connections"... We don't solder any joint in refrigeration. It's a brazed joint... Much stronger and no acid contamination from paste.
Any chance you can do a vrv/vrf video on a typical daikin/mitsibushi system? Would find that very helpful
check out our supermarket hvac video, vrf covered there
New VRF unit video here:➡️ th-cam.com/video/4i1XgcP1tmw/w-d-xo.html
About the refrigerant valve with charging port, iwant to know the inside part and it how's it works
What percentage of pressure drop is expected through these driers?
So, is this whole device considered a consumable?? Doesn't seem like something that could be cleaned without destroying it... Though I guess the hope is that 99% of the time, it has very little to do, and it's mostly just when initially charging a system that there'll be some moisture and/or dirt?? Or... ?? Would be curious to understand more on that... though... I also see that the next video in this playlist is "How Filter Driers Work", so, perhaps I'm about to find out. :)
what does a bi flow filter dryer look like for a heat pump?
exactly the same but with an arrow showing both ways.
Can i use this ice factory
Why do we need this? How does moisture and dirt get into the refrigerant line? I thought it was pressurized gas with no holes in it?
Why is the filter drier placed after the condenser and not directly before the compressor?
There are some you can get for acid burn outs in those situations that require major decontamination, but simply having it on the liquid line is is easier with the lower volume of flow of liquid and immediately helping the metering device from plugging up.
Why was the screen dirty on the wrong side of the direction flow? Seems like the filter would be capturing stuff on the core side not on the other side as yours was. Was that dirt and stuff from the cutting tool maybe?
The FD was new, the durst inside is just from cutting
Very good animation and explanation! Thank you very much, my friend!

How to decide the size of an A/C unit if the old one has rusted label? The flow rate, cubic size and the tonage of the AC? Thanks

I've sometimes wondered, if dirt is getting into the refrigerant, wouldn't that imply an unclosed/leaking system? Perhaps there is a break in the suction line that is pulling in contaminants?
Exactly why they need maintained, to find this out
Not likely, bad installation/servicing more likely.
i would think that eventually corrosion would happen and that's how it would get dirty or clogged
How can the pressure drop be minimal while passing through so tight filters?
Because in the end, the liquid refrigeration is actually going to be getting its back pressure from the metering device (which is a very small opening and the liquid refrigerant is really not flowing that fast with a lot of volume on a standard residential system). Also, If you notice the size of the filter dryer, it's much larger than the liquid line it's serving. So with all the surface area for the refrigerant to pass around the entire outside circumference, this offsets any pressure drop through the fine filtering material and allows it to come out the end without issue.
So is the core like a crystal? Is it edible, like can you eat it??

I wonder if you put water in a filter drier?
Thank u so much for sharing such information...
Great work for learner like me....
Hi there !
Some time ago there were more great videos about VRF training, I wonder where they are now ?
They were deleted but we're planning to remake them better than ever
New VRF unit video here:➡️ th-cam.com/video/4i1XgcP1tmw/w-d-xo.html
if we take it out and put it in sofa ... can we make it new again???
Will drier filter will blast what are the reason
How often should you replace your filter drier?
Never. Under a proper installation, it's there for the life of the equipment and shouldn't have much work to do.
Sir please help upload vrf training vdo more if possible!
New VRF unit video here:➡️ th-cam.com/video/4i1XgcP1tmw/w-d-xo.html
Please provide vrf/vrv videos.
New VRF unit video here:➡️ th-cam.com/video/4i1XgcP1tmw/w-d-xo.html
where does the removed water go?
It's absorbed into the filter and waits. The filter is replaced every so often.
@@EngineeringMindset thanks!
I don't really get it. Why do we need this? I mean if the system is installed precisely than during operation nothing can leak inside or outside. Or am I wrong?
It's impossible to install precisely, air will always get in and in the air is water
