2, 10 pieces of refrigeration tablets need a good quality power supply, withstand the power need to be at least 720w or so, theoretically 12706 workers start current 5.8a.
3, the working current of each piece of about 5.4a or so, 10 pieces of the working current of 54a. ready to about 15 square copper wire (small heat a lot of heat, the temperature of your dormitory will rise)
4, 10 pieces of refrigeration piece of hot section of the temperature is very, very hot, a bucket of water (30 liters then) will not be more than half an hour is hotter, while the dormitory temperature will rise. Installation of large water discharge to the outside and then forced air cooling can be considered, the water pipe must also consider the problem of insulation.
5, the power supply of the refrigeration piece of work will also heat, installed outdoors to consider anti-theft and waterproof anti-temperature is too high
6, summing up, the refrigeration piece of the conversion rate is relatively small, the power supply of the heat itself, such as heat, and so on the heat emitted by the heat is very large, the heat you consider dispersed to the outdoors, or else your dormitory friends will have a problem with the opinion. Share these, you look at the cost, efficiency, but also consider the use of refrigeration film, my Baidu space has a few years ago the production of refrigerator pictures, you can **** you refer to reference, and finally suggested that the study of refrigeration film can still be, your situation can consider doing a water-cooled fan, and simple and cheap.
