In a refrigerator, water is cooled with the help of refrigerant, which is circulated around the freezer chamber. Typically, a refrigerator takes upto 5000 sec. (approx. 1.5hrs.) to freeze one liter of water from 400C. Thermoelectric Modules (TEMs), working on peltier effect can provide high cooling rates while operating on DC electric source. TEMs can achieve sub-zero surface temperatures within a few seconds. An attempt has been made to use TEM for freezing of water. Water can be frozen without any refrigerant with the help of such TEMs while remarkably reducing the freezing time to 3 mins. A design of a rapid icing machine working on thermoelectric effect has been discussed in this paper. To obtain rapid icing the optimum selection of TEM on the basis of cooling capacity and current consumption is discussed wherein, a 500ml cooling box is designed which provides icing in 1.5mins. The design results suggest that, for the rapid icing machine 16 TEMs (TEC1-12706) are required with 4 copper heat sinks of 26 fins each.
