Summary

This study aimed to analyze the mechanism and the basic performances of a heat pump desalination system. As a kind of evaporation method, a heat pump system using cascade cycles of R410A and R134a generates 80°C of heat to the heat pump condenser and transfers it the plate type heat exchanger. Heat generated by the heat pump is transferred through the plate type heat exchanger and the fin tube type exchanger. Through the 3-way valve installed in the seawater supply system to reduce the heating time, water below set temperature 60°C is recycled and water above the set temperature is discharged to the storage tank. The hot water discharged into the storage tank is evaporated and passed through the cyclone and the bag filter to the fin tube type heat exchanger by using the vacuum pump, which condenses into fresh water by heat exchange with the low temperature air of the heat pump evaporator. The amount of hot water that can be produced is about 20l/min and the power consumption used for the entire system is estimated to be 9.3 kWh/m3.
