Only way I ever saw this really work was in a bucket sat in a small chest freezer set at 32F the water in the bucket was frozen but the saltwater in the tubing was not.. I once rewired a dorm box like that e for a guy to try I changed the thermostat to a simple clixon sat at to bring the refrigerator on at 37 F and off at 35F that did O.K but the heat exchange was crap really a chiller is cheaper to run really with the lack of efficiency of the old Polypropylene tubing.. _________ Some of the world's greatest feats were accomplished by people not smart enough to know they were impossible (Doug Larson) |
