Ice Bank Cooling to use off peak power

[nadeem.usmani]

Can someone provide the basic diagram for the ICE storage unit? What is the most efficient way to flow the refrigerant around the tank to freeze the ice?

What exactly do you want to do with the ice? Are you making blocks to be used elsewhere, or an ice bank for chilled water?

A coil in a tank refrigerant through the coil and water circulating around it

Also ice balls floating into a brine solution is a common solution. Brine flowing around the balls will freeze or thaw them.

NNN.
tell us more about your iceballs idea. I have heard of balls of steel, balls of fire, no balls, dried-up balls, whithered balls, happy balls, sakky balls, never iceballs.

Go to http://www.cristopia.com/ I've worked with these guys on a couple of jobs. Their systems work quite well.

You never heard of meatballs? They are raining, at times.
Please follow Peter1 link. Very informative.

Feed the copper coils from bottom to top. If its a large system, break it down into equal partitions for even ice formation using tx valves with bulb at 10 0'clock, insulated and out of the water attatched to the correct circuit of course. Efficiency can be increased using an agitator as mixing the solution will help with temperature variants that occur from bottom to top of the tank. Make sure the copper pipes are spaced apart enough so as not to have them ice together and reduce surface area exposure to the medium... mike.

I can not see a great benefit in ice balls, the ones i have seen are quite large (size of grapefruit 75mm). To total freeze these you need quite cold glycol, which means you must have a low SST on the refrigeration unit, lower COPs. How can mulitple layers of secondary refrigerants be effective.
i am not against thermal stores, but these balls just seem to be a marketting spin. They are being used here in NZ for milk pre-cooling, yes it works as a thermal store, but no way are they efficient, and they cost a fortune!!
i believe the best method is the under used "binary ice", "ice slurry"

HI Usmani, Just wondering if you ever came up with a working solution. I would like to do the samething as well. Thanks
