I own an HVAC company in GA and have been installing VRV since it arrived in GA. Absolutely love it. Great job on this video describing the concept and advantages!
What of the 360 watts of heating removed from the system? 4 people x 90 watts while sleeping x 8 hours is just shy of 3kWh of heat missing from this "real world" demonstration.
There is no cunning to stretch your cool. No explanation of humidity. No demonstration of how the system is installed. Most boat AC systems throw off their heat through the water. 1500 watts is excessive. If a boat chose a modern camping unit, size and build would be excellent. The AC could work on land. It would be lighter and much easier to install and maintain. Thumbs down.
So wait, you only have untethered AC with the lithium option? What about a generator option? I'd prefer to not have my $1.65M boat burn to the proverbial ground due to a lithum fire.
He seems a lot smarter than others on the subject. Would have liked to have asked him, why not use 48v server rack batteries with built-in fire suppression. And why blue stuff when you can get a 10kWh Hybrid AIO for <$1k
Great video, Phil! This technology seems really amazing, and hearing about the planning and designing is helpful even as I think about other projects on my boat.
I was hoping you would go through the numbers of running the system. How much wattage does the 12,000 BTU use during the day & night (with compressor cycling - average dialy usage with outside temp @ XX and humidity @ XX ?.
You do beautiful work. The VRV aircon is a game changer. My 2 “old school” aircons (16k btu and 7k btu) use 50% more energy combined. If/when one fails I’ll be calling. I hope there will be a smaller system (24k btu) soon for those of us with less needs, though the 24v option is intriguing.
What a useless video. The main questions any viewer would have are :1) how big is the battery bank, 2) type of batteries, 3) the BTU size of the A/C unit, 4) how many amp hours were consumed, 5) the run time, and 6) the per hour consumption of amps. None of these were addressed. Rather we watched screens being tapped endlessly. Pass on this video.
Sorry you found this useless! There are more details about this system in the video that preceded it. 1) 22kWh @ 48VDC 2) Victron Smart Lithium 3) 36K BTU VRV Compressor with 54k BTU of air handler capacity. 4) About 100 AH @48V 5) 8 hours 6) About 10-14 amps @48V average at night
Between the regulator and batteries is there anything to protect the alternator if the BMS in the Li batts stop accepting the load? If I understand right the DC/DC charger for the other batts is on the output side of the house.
Thanks Phil- I learn something new every time I watch you speak. Jack only smiles like that when his cabin is nice and cool. I can attest that Jack’s system is working well. Any hiccups have been quickly attended to by the Boat RX team. The AC system is quiet and works as expected. In addition to the Integral system Jack’s boat currently has 540 watts of solar. Phil and his team are great to work with- exacting, careful, great attention to detail plus they are nice folks to be around!
Hi Caleb, every project is different. This one was on the high end of the spectrum for a boat of this size with a total project cost of about $130k. Feel free to get in touch if you want to discuss a system tailored to your needs. info@boatrx.com. Thanks!
It's only similar in that both are variable speed. Frigomar makes a nice self contained unit, however you'd need more than 6 of them to provide the same amount of cooling supplied here. This boat has 2 central compressor units which drive three air handlers each. The capacity of the system can be moved around the boat. So if on a hot day more cooling is needed in the salon and less in the hulls, more refrigerant can be distributed to the salon air handlers. You can't do that with self contained units, Frigomar or any others.
Great to learn more about this emerging market segment in the marine world. You guys are true pioneers! The owner of the yacht clearly found the “right guys”!
@@boatrx …hmm, have you thought about changing the name of your Company or creating a better named subsidiary to BoatRX? (Silent Ship, Green Comfort, CoolBreeze Marine, LithiumBreeze, etc) BoatRX is a cool name, but… “LithiumBreeze Marine Innovations”is hard to beat!
Nobody is using LESS powers than before , on the contrary , boats consume much more power now , but it is easier to incorporate more efficient systems and storage .
