Just a few DC ice dice machines can be found, such because the Snomaster Icemaker, the Brass Monkey 12V ice dice maker, and the Challenger Moveable Ice maker.
These machines are reasonably dear. They value anyplace from $280 to $900.
DC Photo voltaic Ice Manufacturing: Price Estimation
Let’s take, for instance, the BrassMonkey ($280); it may produce as much as 26lbs per day and solely attracts 60W(DC).
You can energy it with just one 100W photo voltaic panel and a 12V, 25Ah battery. With this setup, you’ll get round 10lbs of ice dice per day.
The estimated whole value for this setup will likely be $607.
That is cheaper than the AC ice system launched earlier.
Nonetheless, the principle downside is that the BrassMonkey is at the moment unavailable within the U.S.
Thus far, the one DC ice dice mannequin we discovered for U.S. clients is the extra highly effective and costly ($900) Snomaster mannequin.
How To Produce Photo voltaic Ice With No Photo voltaic Panels: Thermal Photo voltaic Ice
As shocking because it sounds, producing a big amount of ice with photo voltaic vitality with out electrical energy, photo voltaic panels, or gasoline is feasible. How? Through the use of photo voltaic thermal!
In a thermal photo voltaic ice system such because the ISAAC photo voltaic ice maker, refrigeration relies on a vapor absorption refrigeration system: the Ammonia-water system. Ammonia is the refrigerant, and water is the absorbent.
For extra particulars in regards to the ammonia-water refrigeration system, we advocate this article.
With the ISAAC photo voltaic ice maker, the each day manufacturing can attain 1lb/sqft of photo voltaic collector. The price of a single unit is $7,000 for 118sqft.
