Ce s-a întâmplat cu DC AirCon? – Episodul 163
Allways a pleasure to watch you projeckts. Exiting and ambitious stuff you have going on.
You're in Florida. Isn't the mindset there the more Hookers, the better? (cue rim shot).
Excellent video, great humor and tons of information!
Please explain if they're self-contained units. How does the water from the pump get used by the self contained units.
Great site love these guys..
I can't wait to see how this plays out.
There's so much quality you guys do things properly excellent mariners
I was born and raised in Ft. Lauderdale, or as we affectionately call it, Ft. Liquordale. Believe me, there are a lot of Hookers there and I am so glad you found the right one for you.
Sadistics? An apt coinage at that level of power consumption. I will now add it to the list of lies, damn lies, and statistics. Your slip of the tongue has added to my vocabulary. tyvm
Thank you for documenting this, I have a salvaged 56ft cat ( in Thailand ) and am considering to do the same. I may go with only ac units in the berths due to the height issue, and use two 500 gph seaflo pumps, one for each hulll, they are 100 watts each.
Sounds like a great project!
This is awesome. I don't own a sailboat but I am loving the detail on AC vs DC content. Keep it up.
Well, it was interesting to hear your trials and tribulations may pan out to a successful setup others can use- think I (almost) understood most of the content! Rock on!
Kim will go down in history as the first wife to admit on You Tube that a Hooker helped solve her husbands issues! Lol
great team please keep sharing to the boating community :))
Great contain! Now I know why we always have water circulation pump at 120 volts ac on catamaran!
You need an ac, your not a sailing channel your a live aboard want to be I can fix anything boat is fixed. Let’s sell it and start over!
Wouldn’t it be more efficient to have made a custom chiller unit powered by 48vdc? This would have avoided pumping cooling water to the 6 individual units. The chiller can be mounted in the engine room so the noise of the compressor is isolated. AC on a boat requires the most frequent maintenance on any system. The cooling water lines need to be frequently flushed with barnacle buster. Now you have to perform this task on 6 units instead of one. An even more energy efficient strategy is to install a 2nd lower capacity chiller for use at night when the AC btu load is less.
Ty, I wish you would use proper terminology. I know that you know better so please don’t mix up kilowatts and kilowatt-hours. Otherwise, it makes it very hard to understand what you’re really saying.
👍👍👍🧡🧡
Not a sailor but seems the AC cooling water has a challenge similar to cooling the engine with a heat exchanger. Need to suck up water then pump it through restricted hosing and heat exchanges. Seems to me the pressure is more important than volume to get through all the restrictions as long as the volume is adequate for the cooling. Self priming will be necessary if the pump is above the water line and because of the salt water it needs to be easily serviceable. A gear or rubber vain pump connected to a 48V dc motor would fit the bill. Possibly something like a soda carbinator pump or non integrated engine cooling pump. Coupler or belt drive by a brush-less DC motor (E-bike motor ??) Motor RPM based on the exit water temp would be ideal. Fro best AC efficiency you want the high side of the compressor to cool as close to water temp as possible with out wasting too much DC power in the water pump.
One problem you will need to solve with running 3 AC units on one pump is balancing the flow. You don't want to use restriction valves and excess pressure because that waists energy. If running only one AC the pump will be way over sized for the task. The ideal solution would be to run a fresh water closed loop system, with a small pump for each loop and some sort of common fresh/sea water exchanger that is cleanable. Of course that is why they used a central chiller, expensive but easy to engineer and install.
Just the ramblings of a retired engineer. Good Luck

How much Solar and lithium do you have? I have 1,600W Sunpower Solar and 2x 24 230Ah Lithium for 5,888W each = 11,77Kw but i am thinking of adding a third if not forth battery to be able to run air con over night.
Does the hooker pump suck or blow? 😅
I’ve always wondered, why not plumb the system to use ethylene glycol and use a heat exchanger below the water line? Prevents pumping sea water all over your boat, thus preventing corrosion associated with sea water. Use a titanium heat exchanger of sufficient size and corrosion would be minimal. I know it adds complexity and cost, but knowing that my system isn’t rotting from the inside out, and being supplied with a 10,000 gal p/hr pump would give me piece of mind.
I believe DC compressors are ac compressors with a built in inverter. Are these little inverters that more efficient than your central inverter?
You guys are legit my top YouTuber sailing channel. Keep up the work but pump out more videos please. 🙏🏻
