great system, I had a 16,000BTU heat pump Marine Aire unit, using a 12v raw sea water pump to circulate water over the condenser copper lines to remove the heat. This kept our 32' Sea ray sundancer entire cabin nice and cool when it was 95 degrees outside. The condensate would drain thru a tube into shower drain compartment with auto float switch.
I saw where a person ended up grafting a mini split onto their boat. They made a cabinet to cover the outside unit to make it look better but was still able to ventilate. Their draw was 850 watts to cool and it came with a soft start to make it run from an inverter.
@misham6547 it should be just fine. It's made from the same metals your refrigerator is except for the condenser which is titanium, which seems to be the best for salt water. I've run the prototype for 5 years now.
Love the proof of concept! Thanks for posting this and the potential to acquire the goodies to make our own. I filled out the survey and I'd be open to all 3 choices... The DIY Kit may be the most versatile as I plan to apply it to my Class B Sprinter van RV for my land adventures. My pup/co-pilot will appreciate this when I have to leave him in the van on occasion. Boat comes soon... 2022!
I always enjoy your videos and find it hard to believe that you guys don’t have over 100k subs yet. You produce good content and also information on what the sailing life is really like. Good luck and safe travels.
Thanks. I am getting discouraged about our view numbers. Other channels with fewer subscribers get 5 times our views. Maybe we should just film kittens and puppies.
@@Clarks-Adventure You've said it yourself, other channels do entertainment - you are creating a treasure trove of educational content. Your videos are targeted at those already living a sailing life or who are serious about doing so one day. This community will keep going back to your videos as a library of indispensable knowledge. Please don't get discouraged by the numbers - and know that you're creating 100 times more value than kittens and puppies. Keep up the good work!
@@Clarks-Adventure I've seen those other boating adventures where they literally hire young 19 year old models in string bikinis to dance around on the deck. Throwing champagne in the ocean...laughing drunk. lol, you two are too responsible, too crafty, too serious.....those other boating vessels are FAKE, yours shows reality. better to have a good solid normal subscriber base.
The quality of your viewer market can easily trump the quantity of eyeballs simply seeking entertainment. You said yourself that you weren’t interested in creating a business these days. They are. They have a sailing entertainment show business and must keep up the entertainment value with puppies, bikinis, exotic locations galore etc. It’s how they are making a living. Seemingly you already did all that business stuff and set it up so now you get to make only the videos you want to make without the pressure of feeding your “video monster”. …. Just saying.
@@Clarks-Adventure IF you want more views… You just need to be more playful with the thumbs. The thumbnail picture should be an overhead picture of you lying in bed uncomfortable. The text on the thumb should be: Stop sleeping in your sweat. That alone will double your clicks. The video title needs to be expanded to "Battery-Powered Air Conditioning on a sailboat." The content is great! Don’t change a thing with that. Just have more fun with your thumbnails.
The time slots I wish everyone did... saving precious time is essential! That's the first time I've seen a survey on a RU-vid video so that's pretty cool thank you for the time you shared with us. And looks like a really small unit! The amps and the Watts and it uses is incredible but you already knew that
I Love the concept, and I have to agree, that sleeping comfortably in the tropics, or subtropics is quite the challenge on a boat, or offgrid. I have filled out your survey to possibly adapt it to RV boondocking, or grid down scenario. I'm also looking to install on a small boat to camp in while in The Keys. Kudos for sharing your innovations...
Hi Clark, this is just amazing. We are moving back onto our boat in Greece having just had our first baby, and the only thing holding us back is the heat in the boat at night! We have a beautiful CT41 ketch but she retains the days heat so much, its like a sauna at night, so we completely agree with you on this as an issue! Now we have a newborn to look after as well so we are very very keen to get a hold of one of these! Sadly though, we will have to address our battery bank and solar first... Still in the dark ages with the Lead Acid bats...
Thanks Matt The AC units are now available at MarineDCAC.com once you get your system up to scratch. Do you know about my BankManagerPlus? www.emilyandclarksadventure.com/bbms It and a Lifepo4 battery or two and you are good to go. No need to change anything in your charging system.
I´m really interested in this option (and has filled in the form), but I also contemplate an even simpler version where one can attach tubes to and from one or two sleeping bags and only cool and dehumidify the air inside the sleeping bags.
Clark, fantastic thinking and inventing! I love it! I have a 1973 Challenger 32 that I live on in Florida (St Pete). I have a really old Marine-Aire unit that was working 2 months ago, but has a leak. I'm planning my cruising for next year and looking at a new Dometic keel cooler unit (12-16k btu) but then I'm stuck on shore power or a generator or my inverter. I've got 200 watts solar now but could go as much as 800-1000. I'm also ready to pull the trigger on LiFePo batteries. I've filled out the survey, please keep me posted!
Survey done- I love your videos on how to- and all the other ones too. Definitely interested and looks simple enough for the average Joe for the DIY part. Keep them coming and stay healthy both of you. Cheers from Montreal
I'm currently building a cargo trailer to camper conversion, we decided to use a Pioneer Mini-Split. We will know in a couple weeks about the wattage numbers and efficiencies. Specs show about 330 watts on the lowest setting, and about 1300 watts on highest. If we can't dial it down low enough to run on solar, we will order one of your systems to add as a sustainable 24/7 system! Great Videos!!!
Parts for the kit are coming from the manufacturers now. New products on the way Check out MarineDCAC.com to get on a mailing list and as soon as parts come in it will become an order page.
I remember when that compressor came out about 11 years ago. I was blue back then, I can't recall the name of the company that sold it, but it was extremely expensive going for $1,200 just for the compressor alone. The capacity was incredible and was advertised as being able to run an AC and well as a refrigeration system at the same time. Also, setting it up to run was rumored to be beyond the ability of the average person. China came out with a black knock off which runs for about $200 which looks a lot like the model you have. The key I think is to have it pre-charged and on a skid ready to be connected to pre-charged lines like the Cool Blue refrigeration system.
This is extremely cool and I hope your offering this when I'm finally able to buy my boat and hit the water. I'm about a year out from that yet finances willing and would definitely be interested in two or even three of these units for different spaces on my boat. As long as it isn't to crazy expensive that is. This would also help me when I can finally buy my dream in being able to pick a boat that may not already have AC on it and could save me a ton of money. So thank you for making this offering and like I said I hope it's around in a year or so when I know exactly what I need. Fair Winds and Safe Travels, God Bless...
I am very interested in the concept and product, but it will be at least a year before I would want to install one. I will check back after I purchase a boat! Keep up the good work on these awesome videos!
Amazing you are the first to look at s all room AC on boats that I efficient enough to run on batt power sourcing parts and developing a working model makes you a genius cheers to you
I need this. I want it, it's 4:44am and I'm pouring sweat, my bed is destroyed, if I don't get one people in space will be able to smell me. I've been in Florida for 21 years and I have not acclimated (acclamation is a myth). I don't know which kit I would use, but if it's a bucket of parts the bucket will need drainage or it will fill with sweat before I'm done putting it together.
Yes Florida is special. I've lived there as well. It gets cooler as you go south of key west. The DIY will be available first. Fill out the survey in the description to stay in the loop.
I really like the full DIY option, and I would go so far as saying separating the parts so someone could purchase just what they need would be handy as well. For example: someone may want to buy a couple compressors and condensers, but use different evaporators. I am very interested in the compressor alone, because I have a different plan for using it.
Clark you are the man! You might remember that you helped me rig up a mast head tri light with only two wires and a couple of diodes added to the light. Circa 2000 in Mexico. We used that light for years until LED's were available. I love this AC idea. We could have used it in Borneo/Malaysia/Thailand. Though we survived without AC at anchor. SV Green Ghost. Great to see you again!
@@Clarks-Adventure We cruised from 2000-2004 Vancouver - Australia. Then relaunched in 2008 in Australia while I worked there for a couple of years. We left OZ for Indonesia/Thailand in 2010 and by 2017 we arrived back in Canada via South Africa. Back to work in 2017 but managed a three month break on Great Lakes this summer. Getting a new engine, paint job, another sail - etc. You know the drill. More cruising for sure. We've done about 40,000 miles. We need a break from cruising every 5 years to reset our brains and do something else. Anyone tuning in to your channel who reads this - BEST THING EVER! Go cruising.
Hi Clark just subscribed you look like a great channel. Your AC vid is super interesting. I am thinking you should also connect to the #van life community as many are searching for something similar and like sail boats space and electrical consumption is at a premium. Most van people have insulated their vans so your unit would be really interesting. Most van self builders would probably do some of the assembly but not complicated wiring etc although some are brainiacs and could assemble a spacecraft in their garage hahaha
You need to fill out the survey to be informed. We are building a webpage now. I don't think you would want that as you would have to move the water lines. But to do that you would get the kit (which will be available first) and set it up any way you want. Personally I'd just duct the air. There are 4 flanges on the air handler you can connect to duct work.
One month away from owning a 1972 Bristol 38 and I really enjoy your videos. As soon as Im a sailboat owner I'll be more than a subscriber. Im hoping for 800W of solar and 2x 18KW banks of 48v LIF04 batteries. Once I get that dialed in I am going to want to discuss AC & refrigeration with you. Keep up the great work.
Great video. I’m Offgrid and my 5000 btu Air conditioner uses about 38-40amps and I have enough solar to cover that it needs a lot of battery for the night so this would be a cool option for night time.
Great air conditioner Clark, Hope it all works out for you, And if you would like to expand the demographics you could always talk to campers, Or even camper manufacturers they would probably be very interested
Clark, I want one! I have a land sail boat, some folks call it an RV. I can totally see this working with taking the edge off at night. It's a tiny one and an older one that has a massive following made by Toyota! So excited, this is awesome
Those small rotary compressors are compact, but the linear compressor while bulkier are even more efficient. I was googling 'water medium mini-split a couple days ago, and all kinds of variations to see if anyone used water to pass cold from compressor to indoor unit and found nothing. Then youtube recommended this, and I see someone has done it! I was thinking antifreeze, but salt water can go below 0F, good enough for a/c, but not so much for a freezer.
I just bought a boat with something very much like this installed. It doesn't appear to be stock as it looks brand new mounted on new lumber in a 35 year old boat. The ducting is run for the most part, and it seems to all be there. I'm lucky I have a friend that is an HVAC specialist and says he can get it going no problem, and parts are everywhere. Fingers crossed 🤞
We’d love one! Even in the summer it’s fairly cool in the evenings here on the west coast of Florida but we have plans to cruise further south so we will need something! We’d like the fully assembled and charged unit.
Glad to have you sharing this “cool” (your words) idea. Very interested. Will have this over refrigerator. BTW, We were just fine for winter in Bahamas without fridge. Rum not beer. Meat where available. Don’t drink milk. Ate last nights leftovers for lunch next day. Most things in fridge don’t need to be there. We never had butter, Mayo, pickles, eggs, open cat food, ketchup, real maple syrup, mustard, cabbage, carrots. Nothing wrong with many things from a can. Didn’t suffer, wife creative cook.
@@Clarks-Adventure I filled it out. Along with the AirCon I think I’d like to have a water maker, still before refrigerator. No one ever said I was normal.
Good to know. Have you filled out the survey yet? That's the only way to be in the list Also, should be available very soon. For kit form with fill system coming soon after.
Great Job. I’m interested too! I’ve built regular units but I’m fascinated by the little compressor. I’ve put a lot of thought into solar a/c for my sailboat too. You did an awesome job of making it.
Thanks. I just installed the first production unit in a friend's boat. Went well. It's at the end of this playlist. A/C and Refrigeration: ru-vid.com/group/PLsT7_jPsZM5qNlstuF-fdlgjrimo18tq7
Saw a video on RU-vid a week ago someone had a 12-volt air conditioner in a small RV said it worked great just saying. Cost was about $2000... great video thanks for posting.
@@dereknolin5986 , Just got a new phone, still setting it up. Trying to find it the other night and couldn't. I found it the first time by asking on my phone, 12-volt air conditioning videos on RU-vid and it came up. Wish I could be more help.
I just found your channel through “Lady K Sailing” a few weeks ago & LOVE your stuff! I started watching them all from the beginning, Please keep up the GREAT CONTENT!! Gary…
Absolutely Brilliant the thinking you have been doing and the mission you went to find what you thought was invented. I literally just saw a company come out with a 12 volt. Must me the same as you were thing. You have an awesome mind to create. I love hearing ideas they are exciting to grow on. 👍
Hey, I do not know you or your channel but this popped up in my feed. I am a maintenance tech at a factory and we have these super small air conditioners that cool down electronics cabinets. These are bigger cabinets than you are imagining though, maybe 2 feet deep by 8 feet high by 12 feet wide, but I am sure there are larger cabinets out there. People could probably size one to whatever size cabin they have if DIY is scary to them. Using saltwater over air for heat exchange is smart though.
I use an Opolar 5w usb fan to draw the warmest air from the ceiling and send it directly into the AC air intake . My cold air is directed away from the air intake half ways between ceiling and floor directing the air to pass over me in a spiral around the room . The heavier cold air fills up the lower area , forcing the warm air back to the intake in a convection idea . You instantly feel relief and the system circulates effectively and shuts down the compressor quicker. Once I know the approximate time it takes to climitize the air ,I then put the AC on a programable timer (I use a smart plug and app.) I have the system come on for 15 min. each hour . In the mean time I'm only using a 5w usb fan to circulate the air in the room and not the AC fan that uses 50w to 60w for the 75% of idle operation. Note circulating the air properly brings the warm air to the AC faster and thus takes less time to completely cool the room . Notice that window AC blow cold air over the warm air intake . This is a design flaw . You end up sucking in cold air with the warm air and don't get the rest of the warm air chilled as fast. My system draws air from the right and blows cold air to the left over me ... always circulating ... cool air to me ... warmest air to AC until there is no more warm air . You can cool several rooms with a small AC by doing this . Just keep the door open between the rooms. The cold air will trickle on the floor into the other rooms and force the warm air near the ceiling to come back to the AC. (Convection circulation)
So let me preface this with I have fallen in love with heat pumps. Now, my ten year plan involves selling my condo (once its rebuilt from the fire of course) and then buying a boat and moving aboard. Keep in mind I live in New England (Massachusetts actually). So heating my boat is a high priority for me. I am exploring all options on this front, including diesel heaters with radiator pipes leading through out the boat (including under cabinets and bunks and even the lockers) to prevent frozen pipes and the like. I understand you not caring a hill of beans about heat because you’ve given it up for tropical settings. But I just watched an interesting video on heat pumps and in it the video stated that central air systems have 95% the same components as their heat pump cousins. So then the whole process of how a heat pump worked and how it was the same process as air conditioning only there was a reverse feature added that could turn your evaporator into a condenser and vice versa. So naturally, that got me thinking about your system. Why? Because I have a curious mind I guess or because I do enjoy understanding how things work. So, my question is, since you are running your ac only at night, wouldn’t it be better to build a structure outside for your condenser to dump the heat energy your system creates? And how how difficult would it be to convert your system into a heat pump, so it could both heat and cool off batteries?
It does dump the heat outside the boat and there will be a reversing cycle version. Also the air handler I use has a heater core inside it that you could run that hot water through.
This is great. From what I've seen out there, a brilliant ground breaking innovation. I've been cramming to learn about solar. I use thermo dynamics to cool my house. I heat one room in winter to save money. My body prefers a warmer climate. I've lived around the world. Always need a way to cool off to survive though. I might end up living in a box truck I'm working on, needs some help, 75 Dodge CB300, but in a boat in Florida or NC would be great. Might end up in a subterranean hovel in the desert. I'm somewhat disabled, rehabbing from a brutal life. I see a lot of people who could use this, just to make a cool place to survive. I'm very handy, but not too smart on AC systems or electrical. I test as genius, but I know I'm stupid in some areas, lol. Brilliant in others. If this is dependent on a massive source of water that would limit the possibilities, if not the applications could be huge, wide and deep. I know I'm going to need this. Don't know if I'm going to be able to afford it for some time. I have an idea what the battery and solar system will cost. I think if your system creates dry air, a small evap system could cool as augmentation, but there goes the dry air, poof, lol.If it dries efficiently enough, using with seperate evaporative cooling might be synergistic (just need a fan and water flow, which is low volume and can be done by gravity by suspended tank) though usually that sort of synergy gets blocked by reality of physics, but sometimes it can be great. If your system would work in a desert with a small water tank, the combination would be almost a no brainer.
Thanks. Nice of you to say and astute of you to notice. Yes it can work with air cooling. You need to spend more power on a fan and the compressor needs to work harder though. No the swamp cooler doesn't help. You should look at the chemical dehumidifier AC that "Tech Ingredients" showed in his video. I think you might really like to watch that.
Clark, I want one. I'll be buying a boat this winter/spring, and yes.. I want one. I'm saving this video, I'll email you after I start adding gadgetry.
Hey Clark, this is Remco from all over Europe. I watched your videos again now that I have bought a catamaran. It already has 2 ac for 2 cabins each. What I like to know is if it’s possible to compressors on one system? Than I can cool high power with the generator for a our and than switch over to low power on battery. Also like to talk about eddying Lithium to lead, ore making a new bank just for the ac. Please let me know how to connect? Thanks for your content!
I did see a sailboat that used a window air conditioner that was set up over a hatch. It cooled the main salon and likely had enough power to cool the whole yacht which was about 50 feet in length. There is a RU-vid video on it but I can't remember who did it. I am going to do something similar and run an inverter from lithium batteries with about a 1000 amp-hour capacity. At 13V and 80% discharge, then the available energy is 10,400 W-hr. I have 9 solar panels rated at 195 W each. These are going to go over the cockpit as a sun shade. During the day, the panels will put out a lot of power which is dependent on solar intensity. Even on a bad day, I can get 400W of power on average over the course of the day. A 5000 BTU window air conditioner will draw about 500 watts on high setting and likely 550 watts through the inverter. Overnight, with the air conditioner on low, it likely would draw about 400W all in as an average. For 12 hours, that would use up about 4800 W-hr or less than half the battery capacity. The problem for some yachts will be space and layout. This all takes a lot of real estate. A critical factor is the number of people on board. Each adult male body produces about 80-100W of heat while resting and less while sleeping. As well, there is the additional load of humidity created by the human body. One has to figure that into the equation. Based on that, my window air conditioner will likely not have enough power on low setting for more than 4 adults to maintain a dry comfortable temperature.
Seattle's never hot !? we were there on our 4 corners tour, and it was 113* for three days on the record breaking heat wave ! Loved the area though! great vid! I' glad you found a way to keep cool!
No mini split needed I just made a system that makes battery powered AC and cooled seats a non issue. Just run it as long as you want. I am currently building the boat right now. Should be done in a few weeks.
Seen those compressors on Chines website 12V variable speed mini scroller. Nice to see one in use. I am quite impressed with the duty you got out of it. As an RV person my self. As a fridge engineer by trade that has an all round understanding of Solar batteries and inverters etc. After watching this video considered if using just cold sea water running through a finned heat exchanger in your cabin would be enough. But looks like in your part of the world the sea temperature reaches 26C So would not be very effective.The sea temperature in the UK is between 8C-17C and would work well. But inversely our climate is not as hot as the tropics.
It's actually a different compressor. Wish I could use the Chinese version as they are WAY cheaper. This one was developed under a DARPA contract. Although it looks the same. The Chinese claim a COP of 3 for their unit. Mine claims a COP of about 8. And since their only client just now (besides me) is the US military I believe their claims.
Newly subscribed. I love this video ! I'm not great with the back and forth from C to F (I'm 71), but you are fun, and i like engineer inventor energy!
@@cheapcigs9772 it doesn't matter if the lavender smell comes from a air freshener spray, plants, or how ever you want. As long as the smell is in the air. It will repel mosquitoes but the most reliable is plants because it's 24/7 as to a spray. You see. Google " natural mosquito repellent" you will see a lot of different things that will repel mosquitoes
This is very interesting, survey completed. I would definitely be interested in a unit, maybe two, so hopefully you will decide to bring something to market.
I managed to set-up an aircon (temporary) on my oceanis 393. I have 400ah lithium batteries with a victron 3000/12 inverter supported by 4x175w solar panels. The inverter can handle the aircon no problems, and the solar can ‘almost’ keep up so I use my batteries very very slowly. No real issue for the amount I use the aircon. The aircon is just a EUR 300 9000BTU unit for home, but does the job great. @Sailingandscuba
