As an HVAC Tech. You only replace a drier when you open the system, it leaks or rusts, and or gets clogged. Otherwise, they can last the entire life span of the unit
As an hvac tech.no one can ever determine when the drier has saturated of moisture or acids or both and upto what extent or ratio or its a ratio saturation or it is just saturated and sitting idle not absorbing the residual moisture or acids in the system.all these are just assumptions.even after having a micron vacuum process on a leaked system which has a fresh drier installed.you dont know whether the system is getting cleaned or dried up by the fresh drier.any refrigeration system actually needs 1)fresh refrigerant from trusted source of low moisture or neutral ph nature 2)fresh oil charge to to the compressor to a required quantity and quality depending on the refrigerant to be used in the system 3) after leak test by nitrogen,micron vacuuming before refrigerant charge inspite of fresh drier installed in liquid line.
I am a new AC Serviceman hire. I’ve got to say your videos are extremely helpful and make it easy to understand (and explain) the topics of my field. Boss assigned me to make explanations about the AC&R cycle and you have done a great job in helping me do so. Thanks!
The 2 year replacement seems odd to me, since the system if properly installed should be a closed loop. Unless there was an excessive temperature drop, acid in the system previously, or opening of the system they should theoretically last indefinitely. The only times I replace them is when there is a large temperature differential, I open the system, or retrofitting. One commercial setting I did work on however needed acid driers replaced every 6 months because it had a few burnouts historically and the previous contractor didn't clean the system so it was a pain to repair.
I'm still an apprentice, but I have probably installed anywhere between 40 to 80 residential HVAC systems of all kinds and never knew what the filter drier was for, why it was needed, how it was constructed, etc. I appreciate you making these videos as it educates me as an installer on the systems as a whole.
Good explanation 👌 Just one suggestion, you can include and add Expansion tank, Air separator, pressurization unit in CHW system in your list, Also types of CHW distribution system like VPF, CPVS, etc. Again thanks.
And thats why lennox puts the drier inside the condenser (behind the service port).if you need to change indoor txv no need to change it out..because we all know the rule here every new system needs to be hit for 45 min on vaccum or 500 microns. So if youre trusting that when the ref gets saved in the condenser/compressor it should be good
Enjoy the informative videos. To round out oyur HVAC basics and systems you should do a segment about testing adjusting and balancing (or as it become more known as testing AND balancing, as the adjustment rarely seems to get done anymore.). A lot of EITs, service techs and TAB tech themselves could use the information to understand the process and techniques. Also so they can understand the importance of volume dampers and where they need to place them in a duct system. Keep up the good work, Fella's!
Could you please make a video on how hard start kids work I know capacitors are used to create a phase delay therefore applying voltage on a second set of windings but wouldn't a bigger capacitor create too much delay or is it the voltage that you're storing with the capacitor that creates the extra power needed
So my teachers/instructors are really hammering in the notion that the filter driers most commonly contain silica gel, but not many sources I find support that. Is there any truth to what they're saying and does someone have any sources that either support or denounce their claims.
because this is where the liquid line is; this is the ine that carries refrigerant to the expansion valvce; it the valve became blocked then the cycle would stop working.
I have ZR310KCE NEW compressor put old compressor ZR 310KC AND OLD filter drier dcl307s this one ok or not please tell me refrigerant -R22 please tell me correct filter drier
Great work you're doing 👍🏻👍🏻👍🏻👍🏻......... But why are you not uploading new videos on your "इंजीनियरिंग मिंडसेट" channel ? Well I am from india ............
@@EngineeringMindset in HVAC there is a evaporator named "dimple sheet" or many people know with the name of "pillow plate" I think this is a good topic for your next video.
Isnt it efficient to use better coolant almost inert as filter driers makes compressor work harder causing high energy demand,reducing lifetime of compressor due to high workload ,and if it isnt replaced Fd complicates the problems more .and how come impurities like water get into a closed tube system of coolant,
4:25 "The filter dryer has to battle the internal pressures, as well as the atmospheric pressures, so we need a strong casing" Uh, what? Was this worded poorly? Is there something I'm not catching here? Higher ambient/atmospheric pressures decrease the amount of internal pressure that the filter dryer's casing needs to contain...
You can tell this is made by a mechanical engineer. How it works - “the dirt, water, and acids are absorbed...” None of these are absorbed. The dirt is retained by size exclusion, the water will be ADsorbed, and the acids will be chemi-sorbed. The how is works section actually doesn’t describe how this unit operation actually works, other than saying things go in and don’t come out. If you a chartered, industrial chemical engineer to join your channel and help with content.....I’m available
People when are we going to understand your ac system will last almost the entire length of your vehicle life if you change that filter every 3 yrs it's like an oil filter keeps the system good change it

The stuff you're posting are the things that I've always been wondering. Keep it up
Glad to hear you find them helpful

was he repair on the suction side?
I thought that too. That's a $200ish service call every two years... you'll KILL seniors living off social security with that.
I just started a year long HVAC program and all of these videos have been extremely informative. Thanks for much for the stuff you make!!
I've never had an easier time learning than I do with your videos, thank you so much!
Thx for the golden words mate. I follow all your videos n you are my school for electronic n electric parts n how they work I promise
Glad to hear, plenty more coming

_WAITING FOR TRANSISTORS EXPLAINED VIDEO_
Coming soon 😉
Transistor video now live: ruclips.net/video/J4oO7PT_nzQ/видео.html
Great video as always 👍😀
Thanks for sharing 👍😀
Thanks for an excellent explanation on filter drier construction and its purpose of operation.
How does dirt and moisture get into a closed system? Refrigerant breakdown?
What's the sight glass after the filter dryer supposed to look like when the system is running?

Thanks sir 👍
Clear all doubts and good understanding
I'm a little confused, exactly what refrigerant is smaller than a water molecule?
Excellent video & explanations as always TEM! Great work, keep it up! 👍👍😉😉
Great video information 👍
Thank you for creating a video information of HVAC system for parts❤🇵🇭
I thought this was the *new* battery of Telsa, would like to see a video about that! This is also great!
Amazing video bro plz make videos on electronic devices ex. CRO
Very helpful video thanks
Interesting I've seen these before and always wondered what they were. That explains it nicely!
Good information and details thank going on
Why is the filter placed between the condenser and expansion valve?
because this is where the liquid line is; this is the ine that carries refrigerant to the expansion valvce; it the valve became blocked then the cycle would stop working.
As usual great explanation.,
Thank you
Glad you enjoyed
if i cant change it... can i make vagum and pass with nitrogen??? can i warm the filter?
Great work 👍
Thank you
thanks for this vid..it helps me a lot w my work..
Professional 100%
Thanks for this awesome explanation
Bro i just want to know what exactly the impact of PN ratings of valve in hvac system.
The PN rating should be sized to your maximum operating pressure, but below your pressure safety relief valves/ bursting discs.
How do you size a filter dryer?
Thank you.....
Greetings, a question please, what happens in the car air conditioner if the dryer filter is not installed
Great video! How does food chambers vacuum sealer work?
Thank you for knowledge.
your videos are very interesting!
keep the good work sir ❤️
Loved it, thank you.
Hi. Can I ask why is back pressure valve is fitted in refrigeration system?
TheEngineeringMindset teaches me a lot!I love you engineeringmindset!Sub++

How long can a filter drier be effective please?
I have ZR310KCE NEW compressor put old compressor ZR 310KC AND OLD filter drier dcl307s this one ok or not please tell me refrigerant -R22 please tell me correct filter drier
Your table says HVACR.... What is the "R" for?
Refrigeration
Ah.. makes sense.
Happy to be a subscriber. Your videos are great.
animations are very nice. how do you do?
Do you have any info regarding aftercoolers ? :)
Over powered👍
So what happens to the moisture trapped inside the filter dryer?
Dude, why do you think we pull vacuum after opening the system?
I love this channel :))
Links can be found in vedio discreption down below♥️😍 my favorite dailoge 😆

Great work you're doing 👍🏻👍🏻👍🏻👍🏻......... But why are you not uploading new videos on your "इंजीनियरिंग मिंडसेट" channel ? Well I am from india ............
It's expensive and takes time to translate. Not many hindi fans are watching the channel.
@@EngineeringMindset yaa this is right.
@@EngineeringMindset in HVAC there is a evaporator named "dimple sheet" or many people know with the name of "pillow plate" I think this is a good topic for your next video.
Cool
Best info
Great
Cheers for the video bud :-)
Does it use electricity
Just an observation, but your condenser inlet and outlet appear to be upside down 🙂
2:21 does the filter dryer on residential unit also need to be replaced every 2 years?
Depends on manufacturer recommendations, if the system has been opened etc
Mostly likely no
No. Filter driers are not replaced every 2 years. Only when the system is opened.
Don’t know if any system that requires drier replacement
I don't feel like skipping advertisements on his video 🤗
How to select filter drier
Check system components compatible using free software Coolselector
Isnt it efficient to use better coolant almost inert as filter driers makes compressor work harder causing high energy demand,reducing lifetime of compressor due to high workload ,and if it isnt replaced Fd complicates the problems more .and how come impurities like water get into a closed tube system of coolant,
It's risky though, you want to protect the expensive components
@@EngineeringMindset 🤔
4:25 "The filter dryer has to battle the internal pressures, as well as the atmospheric pressures, so we need a strong casing"
Uh, what? Was this worded poorly? Is there something I'm not catching here?
Higher ambient/atmospheric pressures decrease the amount of internal pressure that the filter dryer's casing needs to contain...
Thank you very much.
Welcome
You are a crack bro, thanks
Loop on lithium batteries😀
Volume of the video is slightly low..
Great, but you only showed a single direction flow dryer and not a bi flow dryer. It has to be very different.
You can tell this is made by a mechanical engineer.
How it works - “the dirt, water, and acids are absorbed...”
None of these are absorbed. The dirt is retained by size exclusion, the water will be ADsorbed, and the acids will be chemi-sorbed.
