Clark, you are becoming the top sailing-educator of our generation.
Clark, were you a Teacher before you cast off or were cast off?
No, never taught. In fact I can't work from a plan or script. I just sit down and wing these. Put my toys on the table and started telling a story. Really wish I had thought to draw a vertical line with the left side being gas and the right side being liquid.
I tried to prepare for the "retired at 36" video. Notice all the cuts. Emily made me look good in editing but it took over 4 hours to film that. It was a disaster.
Deep down I don't feel I'm any good at presentation.
For someone who knows nothing about how refrigeration works this was an excellent primer.
You could say it was dynamite🤔???
Get it??? Primer....dynamite???😂
You’re amazing. I’m glad someone is putting real good content here
Thank you.
Please share links to this playlist around to your friends.
Also, the timing of your compliment is fortuitous. I'm at this very moment developing the most important video in my electrical series and deciding if I'm ready to commit to it. You encourage me.
Thanks, some of these are tough to do.
Great explanation. I have worked on ac most of my life. Worked maintenance with my father from 10 years of age. Now mostly automotive. I have inherited some nice gear. Gauges, and a vacuum pump are so handy. I have picked up a bunch of adaptors to use with the small cans used nowadays. This is probably one of the best overviews I have seen, and you really explain the overall function of each part really well, and bring the whole assembly and process together nicely. Thanks for another great episode.
So nice of you to say.
@@EmilyAndClarkdo you know where I can get a control unit just like the one you held up during the video? Thanks!
eBay
Or if you want to pay more. Rparts.com
Clark, thank you. You're a great teacher. You enthusiastically make it simple to understand. 10/10
Mr. Clark thanku 4 such well thought out video.. im also very gr8ful .. i wasnt deceived .. many videos.. hav titles.. that dont match the content.. u hv 2 put up with.. 98percent clowning with 2percent.. info.. not with ur video clark.. very informative .. and especially clear.. once agn thanku..
Thanks.
Maybe you would enjoy watching through our back catalog of work?
For the first time, I can say I actually, really understood how they work. Thank you!
It's nice to see you are getting better now Clark from that virus and know i now a bit more about refrigeration .
Thanks Mat. Next week's video was filmed earlier. Yeah, you will see I look worse. It was a hard day. I wanted to be in bed not fixing a fridge. But we do as we must.
I’ve spent the day falling in love more with your channel and you guys. Found you months ago through the hybrid battery posts, which we’ve done on our UK narrowboat. Today has been different, you’re becoming addictive viewing 🙏❤️
(I absorbed your advice before even buying our boat) many thanks 🤗
Terrific explanation! I have saved this video in preparation for my loop adventure.
You have done the best simplified explanation of a basic refrigeration system I have seen - so thanks for a great presentation.
You're very welcome Tim.
Excellent video Clark. I'm looking forward to the rest of the series and the ones on your aircon. Thank you for sharing. Glad to see your cough is getting better!
Thanks David
Very well put. As a tech that services vehicle A/C systems I can confirm this is good stuff! Looking forward to trying your system!
fantastic info, thank you very much Clark
I want to say a big Thank You to you! We just had a problem on our refrigerator and quickly identified the root cause by using your technique. It saves us big money and time!!! 10000x like to this video!
YES YOU DO deserve a like. Knowing how a fridge or AC etc works is so important, especially in the cruising life when you find out that bathing in your own sweat every night is less attractive a proposition than you'd think, especially if your medication causes you to sweat more than usual. I remember learning this stuff 50 years ago in Physics classes at secondary school (UK), and have never forgotten it, (backed up by many explanations from my dear dad).
Thank you,. So nice of you to say.
If you choose to pass this on to others this playlist might be more helpful then individual videos.

Clark .. listened to your explanation of refrigeration again and you didn't say you were ever a refrig tech ..but you must have been by the way you explain it.. .. it is a cool thing to learn and understand.. you woulda been a great teacher for a trade school. Kudos clark.. get ahold of teal from onboard lifestyle he needs your unit and your friendly help and knowledge asap.. told him bout you awhile back and I'm sure he will be very happy and surprised to hear from you.. thanks Clark ... Teal is a real likable good guy as you and you both will get along 👍😃 great
Nope never have done that professionally but I am an engineer. I just start from first principles.
Is this a guy with a RUclips channel? Feel free to have him contact us.
@@EmilyAndClark yes he has a utube called onboard lifestyle and a beautiful family and a most beautiful catamaran he practically remodeled to be the the best cat on the planet Clark. Missed you saying you were an engineer but heard it just now on the vlog as I'm writing you.. you are the absolutely most interesting to listen to.. I'll tell him to get ahold of you asap.. you can watch his 200 vids ... From the very first each one is better. Thanks again Clark ...
Thanks Allan
@@EmilyAndClark I just left teal the message .. thanks again Clark. You know Clark I taught myself this trade and haven't been stumped yet ..worked on ice machines light commercial refrig .domestic refrig domestic and comm ac too .. computer and non computer run and half and half too. Did go to college for veterinarian science but never finished that goal after 6 years of units .. saw refrig was for me and am just about as happy with it from a science perspective...
Yes it was one of the more satisfying things I got my brain wrapped around.
Have you seen my air conditioner?
MarineDCAC.com and videos here.
Well explained (I do know 'Fridge) I always start with "What temperature does water boil at?" Most say 100/212. Then I ask how a pressure cooker works. Some do know. Change the pressure and the water boils at a different pressure. Take a suitable liquid, drop the pressure to boil it at a low enough temperature. Take the resultant vapour and raise the pressure to a boiling point above ambient. You can then let it cool and it goes back to liquid. 'Fridge.
I use the pressure cooker analogy in next week's video (which I filmed two weeks ago). When I'm vacuuming the system.
Thanks Jonathan.
Good video & explanation. From a refrigeration tech in the UK. Laughed at the "voodoo" bit because I remember my mentor telling me 35 years ago that refrigeration is a black art lol.
From a guy who knows refrigeration, you did an excellent job of highlighting the system, and the most common causes of failure. Loved the way you used the term "voodoo" to reference the other more physics items and diagnosing. heh heh
Great video.
Cheerz!
Thanks for helping connect the dots. Was told what needed for gauges. Now I understand 😀
My fridge quit on me after about two years from having it repaired in San Diego. I had another sailor in Ensenada try re-charging it several times. I soon realized my repair guy was not really up to the task. Finally I bought a new Adler Barber unit and new evaporator. Problem solved. The guy in the next slip helped a lot as trying to install in my 36 Catalina required someone more flexible than me. Time. For a bigger boat. Lol
Oh yeah, You DO deserve a like Clark )))
Thanks - very interesting and worth knowing thing
And yes, the captain (or sailor) should know and be able to fix his vessel anytime at any place, have spares, or at least be able to find and define the reason for malfunction - ways and timing of repairs.....
Great video. Trying to work through some issues with our fridge and it was a good primer 👍
Happy to hear that
Good video.
I just managed to fry my frig controller. An interesting problem that you may have better insight into than I do.
I have installed LIFEPO4 - 2 banks of 100AH drop-ins (Redodo) along with double bank lead acid for start. All was going well until about 5 hrs on eng at which point the lith banks were say 13.3v and I started getting A/P and electronics failing. Running below, my cheapie panel gages were showing 39V !!! Before being able to shut down all charging, the frig went out as well. The frig controller has the main diode burnt up but no other visable damge on the PCB.
Post-event, my regulator is a balmar AR5 and looks to be OK with field at 11.xx at eng start, dropping to 7.xx after say 15min. 5-6 fuses were blown and saved the AIS/VHF and A/P etc. All fuses that blew (were originally on lead acid), have had to be replaced by higher rated fuses (2A on A/P holds at 5A, VHF from 7.5 to 25!! etc) . So it looks maybe that as the lith bats approach full charge, the amps drawn by stuff increases. This is counter-intuative. I would have thought that as volts go up, the watts would be the same under the same duty, and the amps would drop.
Have you ever experienced the same thing?
Have you any idea how a standard 80A alternator could put out 39V?
Do you think there is a potential that the LIFEPO4 built-in BMS's could be the source of the high voltage?
Returning to home - port and shutting down, both house and start bats are showing normal volts at 12.6 and 13.3 and are holding charge etc , and I do not see any repeat of high charge voltage. Since failures happened only after several hrs on eng it would seem that a thermal run-away type event was happening?
Any insights would be appreciated, love you site

You have a few misunderstandings here. And you must understand I can't do debugging through RUclips comments. I have over 80k subscribers and a life.
If you would like my help there is a Patreon tier called Dream Believers that gets you phone access. We can certainly get this all sorted.
Thank You! That helped me a lot to repair my fridge. Thanks :)
Your very welcome
Thanks Clark!! Great post!!
I learned so much about how to fix my refrigerator! I learned to anchor near you!
Thankyou very much for the training of the fridges, it was great to remember these things i was supposed to listen to the teacher about when i was an apprentice so very long time ago.
I thing i did remember from those days is that a fridges may work fine for a given ventilation area installation in say New York may not work so great in say Cuba due to the increased mean outside temperature. So thanks for the tip on installing a bigger fan boaters may need one for the hotter temperature climates
regard
Very helpful, thanks to you saved at least 100€ by not looking for a marine for a basic thermostat failure
Coming from a person who thinks he can fix everything (me) your video was great. You are incredibly engaging... I hope we cross paths one day. cheers
Me too.
The thumbs up isn't big enough, absolutely love all the content on this channel.
Share on social media then!!
Thanks
What a great tutorial. I’m definitely going to be watching this several more times and also saving it for future reference.
Thanks. So nice of you to say.
Great video, I do love the pedagogical way you are speaking!
Thanks Asen
Thanks! Very good video.
Love the videos!!
Great video! Thank you!!
Uncle Clark done learned me.
Hello Clark - so great! Really top stuff. I am a mechanical engineer and I know this stuff, but now I know it better! Thanks so much. I wanted to ask if you have any tips about re-configuring a 5000 btu window unit and use the parts to custom adapt to an older boat - 1965 Pearson Vanguard. I've got plenty of room to fit it into the boat - it's not 12v but it dehumidifies while at the dock (I weekend lake sail and don't really have a solar panel charging system to speak of or a battery bank, only 2 lead batteries w small individual solar chargers, I just use shore power & a Honda knock-off generator if needed). Right now I have the window unit hanging in my hatchway (looking as nice as I can make it). I just leave the entire unit on the dock when I go out sailing for the day and put it back in place before I leave the dock to go home. As a dehumidifier it works great, very efficient. The condenser actually uses a condensate tray submerging the copper line to help cool - air/water cooling. New less than $100 on Amazon. Anyway, I bought a spare and I want to deconstruct it and use raw water to cool the condenser and pipe it up out of the way unseen. My Honda knock-off gas generator also can run it w 120V output if it ever gets really hot while on the hook. Even if I totally botch it, should be fun and I know that I will learn plenty. I figured you might enjoy this challenge. Where am I going wrong ? Thanks in advance.
I kinda took this a few steps farther with this
ruclips.net/video/xF113aUlZgo/видео.html
Uses very little DC power.
It's now available as a kit at MarineDCAC.com
But sure you can do it that way if you don't mind the power consumption. If that's OK with you then go for it.
God i love these. Thank you so much for sharing your wisdom. One of the few sailing channels that actually make contributions, the two of you are inspiring.
What? Don't like all the "Look at my cute butt while I spear fish" vids?
Guys, you're views are not what they should be. Suggestion: Get a cat and make sure about 25% of the vid features the cat doing...well nothing. Cats are not dogs. They're maintenance free sociopaths. Get a hypoallergenic breed. Engineer life jackets and other "Clarky" stuff. Make a cat jet pack or something or a cat scuba suit.
I've never sailed, but watching these types of videos, I know that I would have an issue with drawing the line between floating garage or pleasure vessel. I know that I would have an inclination to want to keep spare parts everywhere for any contingencies and maintaining that balance would be difficult. I know you have to draw the line somewhere and that space is of the most import. I really enjoy the maintenance side of this sailing thing and I see that there's always plenty of it.
Looking forward to the A/C video!
Well done, very helpful, thanks from a fellow cruiser/RUclipsr
Thank you, Clark, for this very explicative video! I can’t wait for the next parts.
Next one is finished and available to patrons now. Should be published next week.
Awesome Video mate... the other thing to look out for is the door gasket/seal, they harden up and/or get damaged over time letting in (warm) air/moisture, and can show an ice build up and warm beer :( eh...
Thanks for the education!! Realy uselful. Sad to still hear you coughing, i hope you will recover soon. Take care!
Thanks Capt n
We just ordered some spare seals for the quick coupler. Good to have as spares
Yes the right spare at the right time means everything.
Fir those I tend to just cut them out and solder the lines together. I didn't even know there were spares available.
@@EmilyAndClark Cutting them out seems like a good idea, they seem to be a frequent failure point, ours we all dried up.
Clark and Emily for President 🇺🇸🕺🏽💃
Exelent info thank you happy sailing
Thank you for sharing your refrigeration knoledge Clark . I am troubleshooting the frigoboat system in my sailboat now. I was looking at your little material list and you give us the mechanical thermostat link. could you provide a link to the digital thermostat as well ?
The digital I use is actually for another application
I have to modify the main circuit board on each.
So I don't have one I can recommend
Such an educative vdo. So easily explained. Thanks a lot.
Ty , allways so much educateing fun to watch. Seems you are healthy again :-) Sail safe the both of you.
Well this is neat! We just did a major fridge rebuild/reinsulation on our boat a few months back... and just got the video on RUclips. We would love to hear your thoughts!
I didn't see the old interior but I would have been tempted to just pour in some expanding urethane foam.
I don't think the fridge front is exactly a bulkhead. That's why it wasn't taped in.
The cabinetry looks great.
.....and I NEVER want to live in CA
@@EmilyAndClark thanks guys, we actually have a blog article coming out that gives more details (and how we know it was a very poor attempt at a bulkhead) ... excited to share more soon and super stoked you took the time to check it out! We love your videos!
I love your videos, but as a mechanical engineer I have to make a technical comment. Your explanations about refrigeration and in general your explanations of physics is spot-on, but you lack precision with regard to heat and temperature. You have stated a definition for heat that is instead of temperature (perhaps a slip of the tongue?). Temperature is a measure of a substance's average random molecular kinetic energy - i.e. how fast the molecules or atoms are moving (which increases if you compress a gas). Heat is energy in motion due solely to a temperature difference; i.e. heat always flows from hot to cold. The compressor (and expansion valve) helps change the temperature and allows us to move the energy in the direction we want - i.e. a "heat pump" which is also an accurate term for a refrigerator or AC unit. In an electrical analogy, temperature is voltage (potential) and heat is power (energy flow).
What a great video!! so informative and simple to understand! THANK YOU
You're welcome Tony. Glad it helped
@@EmilyAndClark I had a "pro" install our Seafrost 12v system and the hoses are frozen - I now know why - thanks - too much freon. I can fix that now because of your excellent explanation.
That's nice to hear. Thanks for passing that back. Happy to help.
Great video Clark - perfectly pitched - looking forwards to the next one & great to see you recovering.
Whenever I hear R12 (Freon) it always reminds me of it being invented by Thomas Midgley but that wasn't his only 'claim to fame' - he also invented tetraethyl lead as an additive for petrol/gasoline!!
Also managed to kill himself with his construction of ropes & pulleys designed to get him out of bed after he caught polio ...
Good job!
Oh boy, I wished I had seen this a year ago when I installed a new fridge (components, not the box). Extremely useful, thank you! Yep, we broke that weird 'wire with gas', luckily the company gave us a whole new system!
After seeing this, I'm left wondering whether that wire should be in the fridge, or outside. We've the cooling element in the fridge, that little motor thingy with fans age controller about a meter from it, and that gas cooling wire mostly outside the fridge. It seems to me that we ought to put it as close together as possible and put that wire in the fridge as well. However, since it's so fragile, I'm hesitant to do that (as inside it'll be too easy for my beer cans to accidentally hit it while sailing).
Don't worry about it. Someday when you need a gas charge you could cut those connectors off and shorten all that copper and solder them back together properly. Those connectors leak!
But it's fine as it is.
Interested and looking forward to seeing what you build
Definately “nerdy” but great explanation Clark.
Thanks Michael
Very usefull. Thx much!
HAHA! When the beer starts to get warm, thats when its panic time and there is a serious problem.
Good intro to refrigeration! Well done!
Thanks Herbert
Refrigeration is cool!! 😜 My home is heated by a backwards fridge. Here is Sweden we have -20C, sometimes -30C nights in winter and all my heating comes from a ground source heat pump, which is a big reverse fridge taking 8C from a borehole and boosting it up to 40C to run around underfloor heating circuits indoors. It’s so energy efficient, my electricity bills are a quarter of my neighbours who have direct electric (resistive element) heating. The engineers who first developed all this stuff did us all a huge favour 👍👍
Those systems are just now catching on here in the U S and are so high priced it will take 18 years to pay for itself. And that's when parts should start to wear out.
@@popsoldboats3406 It sure was expensive - we paid 169k Swedish kronor in 2016, that’s around $20k. But we no longer have to pay $1,200 a year for firewood and our electricity bill dropped by a third because the hot water production is now so much more efficient than the old electric immersion heater system we had before. My estimated payback period on what we spent is 9-10 years, assuming electricity prices rise around 3% per year.
One could build their own. I'd start with a mini split heat pump. The one I have in my land house costs about $750us. www.ebay.com/itm/PIONEER-12000-BTU-20-SEER-Mini-Split-A-C-Heat-Pump-115V-16Ft-Full-Install-Kit-/293615688932?_trksid=p2349624.m46890.l49286 and I like it a lot. You might want two of these or more depending on house size and desired zones. Burry some hose or drill down.... Add a pump and replace the mini split condensers with water heat exchangers (see next week's video). And you have a fine system. Reasonable price.
Where my house is located the weather is mild so I just use air cooling for the condenser. But if I lived someplace colder or of I had a pond on the property I'd set up this kind of system. Total cost for a 24,000btu system would be $1,500us plus developing the geo thermal side, but that can be a ditch and hose. Definitely a DIY kind of project.
This wouldn't give hot water without more modification but though we grew up in COLD places we never plan on living where water can't be heated by the sun ever again. I hope to never see -40 again in my life.
@@EmilyAndClark that’s a really interesting idea and it would never have occurred to me to DIY it. The heat pump installers all seem to subcontract out the borehole drilling part anyway, so I’m sure an individual could also get one of the drillers to drop a 150m+ deep hole into their garden and install the necessary U shaped, ethanol filled plastic pipe within it. Too late for me, but I hope someone sees your suggestion and takes it on as a project. 👍
Yes, and if you already have a water well I'm sure you could work with the existing hole.
Another great video, thanks Clark!
Love this type of technical videos! Thank you sir
Food is so much better when it isn't rancid/rotten/spoiled! ⛵ 🍲
What about taking apart the control unit and fixing it like you would a circuit board?
Awesome tutorial! Looking forward to the next one!
You folks are great 👍🙂
Thanks for the education!
Great video!
Thanks Leandro
you bet you deserve a like!
Thanks David
Few years ago. A lot taxi owner on Australia were putting LPG in the a/c. Ice cold, but dangerous in accident.
Yes it actually is a better refrigerant and I would consider it if it was comparable with the existing lubricant.
Not in a boat where a leak would accumulate and be really dangerous.
But a car, I could be sold on that idea.
@@EmilyAndClark few condensers blew up if front of the taxi got damage in an accident. Events Jesus authorities picked up that they are using LPG in the a/c. Back in the 90s there was little valve on the filler U could under do and a mate used to put his can coke where the gas came, can was like ice.
Clark - I have been trying to figure out my “broken” freezer for the past 2 years and was about to give up and call in a service tech when I found this video. Using your trouble shooting tips, I quickly found that my digital thermostat was the culprit - it had died. I simply disconnected the temperature probe wires, connected them together and voila - the compressor started right up and the freezer started to get cold!
I have now replaced the thermostat with an STC-1000 digital model that allows me to set a temperature and an offset value (in Centigrade). Being new to refrigeration, I am wondering if you could provide some directional guidance for what values I should use to optimize the performance of my freezer and its related compressor. I have initially set it at -2.5c with an offset of 3 degrees.
Thanks for any advice you might have.
The higher the less power you use
But sausage and ice cream won't freeze hard.
There is a way to adjust both the temperature and the gas pressure to really dial it in. I guess I could do that some day.
I hope you subscribed and watch my other stuff. If you find something useful please share it with friends.
Fantastic video! Thank you, sir.
Top notch ! Great info. Thanks.
cool video ❄️
Awesome, as usual...
Thanks Curtis
Hi Clark,
Great video, thank you. I have a sailboat based in England. I have a problem with my fridge where there is a blockage, the local refrigerator guy said that I need a new system at a cost of £1100. Excluding VAT. The engineer maintains that oil from the compressor has got into the refrigeration lines and has developed a bad blockage. The fridge is Frigoboat.
Any help or confirmation that this can actually happen or advice you can offer will be appreciated.
Apparently you can’t buy or use R134A gas in the UK unless you are a certified engineer. It’s law
You have a lot of LAWS that side of the pond. I recommend you watch your voting in the future.
I've seen this and I have a solution. I've used it successfully but never heard of anyone else talking about it. I guess you could do the trick and hire your guy to recharge the system if you can't find any gas.
So here is my trick. You need high side access. Hook up your gages but remove the high side hose from the gauge manifold. Apply gas pressure to the low side (you could use compressed air, I use refrigerant). That tends to blow the blockage from the cap tube. I guess if it was really stubborn you could use some acetone or something to rinse that side and vacuum to remove it.
Vacuum and recharge. So far I've been 100 percent with this "fix". Whatever clogged the system is still there but in the two systems that I still have contact with it hasn't reoccurred in like 5 years.
Worth a shot to save a grand.
Awesome video
Thanks Deb
Aye m8’s, great stuff and loads of info. For next part: Do you carry a cylinder of Tetrafluoroethane on board?
Yes I started this cruise with about 40 lbs of it. But I've gone through a lot of it. My air-conditioner uses it and I fixed a LOT of fridges last summer with lockdown.
Great video.
Thanks Kelvin0
Thanks Kelvin0
I will be glad if you help
Great explanation and you didn't even have to use the equation PV=nRT...that would have made me wince forcing me back to my thermodynamics class in my college days! LOL
This is some amazing content on this channel
Thanks
Excellent! How bout a '66 fridge system in an old Chris Craft dog....to replace??
Yes. You will see a terrific savings of power. Those old induction motor systems suck power.
Incredible
Thank you Victor. Hope you enjoy our other videos and please consider sharing links.
As always, a great vid. Thanks!
You got a G2 CME hitting earth Sunday .
Brilliant video. Hoping to learn the dark arts and help other sailors keep cold beer 👍
That will make you very popular!
Talk about coincidence, I was watching one of your vids this morning in my kitchen, opened the fridge and the damn thing has blown 😂 just wondering if its worth getting a new one that will fit on board a boat for the future, im taking it as a sign 🔮🛥️
Great video I learned a lot!!!
Great teacher! thank you!
You're welcome and thank you for choosing to support us on Patreon. I just sent you a note.
Another great video Clark! My fridge works fine, however I cycles every 10 to 15 minutes. I have sprayed foam insulation all around the casing and replaced the thermostat. Any suggesting?
What's wrong with the cycle
Is it getting too warm between cycles?
If so that's your thermostat. Either there is a hysterisis setting to adjust or it's just tacked.
do you have a video of when you made the copper evaporater plate?
No, I made that before we had a channel
thanks
You're welcome Michael
Thanks. Good information.
Your welcome Bob
rich video!
thanks for your work
Love this thank you !
Vera usefull.
