Has any had experiecne with DC Airco Air Conditioning, [at http://www.dcairco.com/], 24 VDC roof top air conditioners (also avialable in 12VDC and a split system) I have no idea on the prices or durablity and what service is like but would like to know. It is remarkable to be able to get 9,000 BTU from only 1/2 kw of 24 volt power, might just make sence to stay with my 24 VDC auxilarey genetator/house batter system and the small 120VAC inverter and not even bother with a bigger diesel generator. Would be easy to run 3 or 4 of these on the coaches 270 amp altenator and have plenty left over to drive with and charge batteries going down the road. Of course the big if is the price to purchase and maintian , and I have not found a North Amercian dealer yet! | ||

That might be fine for over the road, but what do you do when you reach your destination out in the desert somewhere or otherwise where there is no power pole? Richard | ||

I have a 4.2 kw 24 volt genetator set (have a few ,surplus military units,)that I run to charge house batterys , only with these A/C there will not be a need for a bigger inverter and perhaps of greater note is the claim that the efficency is so high they are using less than 1/2 of the power of a normal rooftop AC,less than 500 watts at 24 volt DC to get 10,000 btu and no start up surge (almost sounds like like efficency that could not be done, but that is the claim). With this system I could run 4x 10,000 BTU and still have 2 kw left over for charging and runnnig the small inverter. Of course that is a lot of carbunckles on the roof, but the air would be well distributed without any additional ducting. When parked near a 120 VAC pole power back to 24 VDC there would be loss in efficency but pole power is a lot cheaper than generator power, not even including the far greater efficency claims. | ||

DC motors suffer lots less from needing HUGE amps just to get started. Many house air cond have SER of over 20,so an efficent air cond IS possible. The shame is the AC mfg dont use "universal" motors, these suffere not at all from low voltage , they just make less power. An all DC coach makes sense IF you have enough batts to run the house stuff TV DisH Microwave ect from an inverter. With a DC fridge and air cond , the inverter could be a 1500W $200 cheapo , the TV doesn't care! FAST FRED | ||

It does 2650 Watts of cooling using only 470 Watts of power? I know that A/C power is goofy, but is that right? Anyone know where to buy these in the states, or even what the cost is of the DC9000? And if these work, anyone want to buy my pair of Coleman 13.3k?  | ||

yeah, they work great! I'll give ya' 200 for the pair of colemans. | ||

RedDot...www.rdac.com makes a 22,000 BTU DC unit and may handle the Dutch DCAirco units. In Seattle. Andrew. | ||

went to check on your site for that 22,000 BTU unit but came up with a "looks like a virus" by google, can you check again please Andrew and do you have any idea how much n that large unit? I understand that there is a dealer in Canda but have not had luck getting a response yet. Will share when I know more. | ||

Well Andrew I fianlly found REDDOT website at http://www.rdac.com/Pages/product_pages/units_index.html#Anchor-Rooftop-47857 and have not been able to find any 24 volt driven AC compressors, and let alone anything with such "magical" efficentcy claims so maybe you can help steer us hear. Did hear back from the Canandian Espar dealer that will be the wholesaler for the http://www.dcairco.com/ DC driven "magicaly" efficent roof top A/C units. I pushed him for a price guess (he told me they have not yet finalized the details of the distributorship) and he said only $ 4,000 for the 9,000 BTU unit. Guess we will be waiting a few years for the price to get real before it becomes part of our conversions if that is the case. | ||

Just talked to Red Dot - they don't make "free-standing" A/C units, all of them are meant to be used with a compressor running off a belt off the engine. | ||

If anyone is in the Montreal area and would like to do some recon on this New to Canada product, the Espar rep told me they plan to have some sort of a event around this "magically efficient" DC driven Air conditioner. I am unable to attend, but would be very happy to set you up in my place when it happens this spring. Contact me at truthhunter@shaw.ca and I will forward your contact to the Rep,as long as you share your findings with on the board. Obviously such a device could have far reaching ramifications on some conversion designs once the price becomes reasonable (as the AC is the biggest electrical need on conversion with propane cook stoves) | ||

Hey I thought it was a good lead anyway. RedDot does make AC units for big machinery. Even rooftop units such as their model R-9727 that do use a 24v. condenser etc. So you have to use your own compressor. Oh well! Who'd a thunk it. They even have a business relationship with AirCo. AirCo must supply components to them. No one claimed RedDot had "magical" efficiency numbers the same as AirCo though. Skepticism aside, it seems as if the efficiency of AirCo units comes at a high price. I'll find a Euro price for the AirCo units and we'll see how far the $4000 price is off, if it is. Andrew. | ||

AirCo 9000 BTU Units are priced at 2700 Euro in Europe. At $1.18 conversion rate that is $3186 without shipping. AirCo sent me a bunch of specs and promo literature. They do sell to Red Dot. Still too expensive for AC though. |
