Ice Making

Article Summary   by:darkblue     Original Author: bng
ª
 
Ice making starts with filling the ice cans with clean water, it is then dip into a brine water which has a salinity level between sixty to eighty percent and temperature between twelve to eighteen degree Fahrenheit. Temperature in the brine tank is maintained by the evaporator. The evaporator is part of the refrigeration system where the refrigerant undergoes a change in state from liquid to gas as it absorbed heat from the brine water in the brine tank. The gas refrigerant is then compressed by a compressor; at that stage of the refrigeration system, the temperature of the gas increases as its pressure increases. The high pressure hot gas refrigerant undergoes a cooling process at the condenser; at this stage, as the refrigerant cools down, it returns to liquid state again and then it goes to the ammonia receiver and it will again return to the evaporator because of vacuum that is caused by the suction of the compressor.The cooling process in the condenser is caused by the flow of the cooling water that is being pump from the cooling tower. As water passes thru the condenser heat transfer from the hot gas refrigerant to the cooling water. The hot cooling water then flows to the cooling tower to be cool down by the cooling fan and then it returns to the condenser.
