To glycol cool the lines from your cellar, you will need to put together a 'python', a recirculation pump, a reservoir, and a cooling device. The cooling device can be a small refrigerator, as you will want your glycol to be only slightly colder than your beer. The Inner diameter of the coolant line should be larger than your draft lines to avoid burning up your pump. To construct your 'python', simply loop your coolant line so that the intake and return portions run parallel, but end at the same point. Lay out your draft lines parallel to the coolant lines, and attach threaded fittings to both ends. Wrap the whole assembly into 1 bundled cable with insulated tape. If you can not find it, try finding a more generic insulation, and wrap it in uninsulated tape. Be sure to give yourself some extra length when constructing your python. Place the reservoir inside the cooler and recirculate the glycol. To clean the draft lines, link them in series with fittings, turn off the glycol pump, and recirculate hot caustic.
An issue you must consider when pushing beer up from a cellar is the head pressure in your kegs. You will be fighting both gravity, and the friction in your draft lines. If you use your normal pressure settings, you will likely notice a greatly decreased flow rate. Increasing the head pressure will over carbonate most of your beers, so your only option would be to use draft lines with a larger diameter because of the lower friction coefficient. Unless, of course, you want to use mixed gas. You should note that the glycol lines will keep your beer cool on its journey to your glass, but will not effectively cool warm beer.
I hope this is helpful.
