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.

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.

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

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.

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).

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

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.

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).
@EmilyAndClark

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.

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.

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.

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 👍👍

@@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. 👍

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.

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.

Great video as always! Looking forward to next week. Have you given any thoughts to using a raspberry pi pico ($4) or an arduino microcontroller to replace the control unit for the compressor? Seems like a no brainer if you can replace a $200 part with a pico. (Also, apologize if you get multiple comments from me, had some issues with YT this morning...)

There is a lot going on with the controller. It's running a 3 phase brushless. Do-abel but that's a lot of MOSFETs to coordinate. It also does a good job of watching for loads of error conditions and doesn't seem to have corrosion issues. I save my microprocessor efforts for things I just can't buy like the charge controller project. But if you built one there just might be a market for a cheap controller box. Go for it. Send me some I'll test them!

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.
