The saline water is poured into the evaporator chamber and allowed it to freeze up to -4 degree Celsius. After sometimes, the remaining water is drained out from the evaporator chamber. Then the ice formed is melted using the hot refrigerant vapour that is being bypassed straight to the freezer from the compressor using Solenoid valve. It works on the fact that the ice crystals formed from the salt water is salt-free. Using this process, fresh water of less than 500ppm can be achieved at lower price with low energy consumption.
