Abstract
This paper presents an experimental study of a freezing desalination plant that uses deep seawater. The experimental apparatus is composed of a compressor, a condenser, an expansion valve, and an evaporator. The capacity of the compressor is 0.75hp, and seawater storage tank is 20L. R134a is used as a refrigerant. The performance characteristics of the freezing desalination system, such as ice productivity and seawater temperature variation, were determined in an evaporating temperature range of -15 to -5℃ and a seawater temperature range of 5 to 26℃. The tendency of temperature change of heat source is similar to each other for each evaporating temperature, and after operating system for 50 minutes, the tendency of temperature change in the storage tank are similar to each other for each evaporating temperature. When the heat source was seawater from heat pump discharge, the ice productivity decreased by about 4.3%. In order to evaluate the features of desalination water, the mineral content (Na, Mg, Ca, Cl) of the ice was measured. The results showed that the ice had the maximum mineral density at -5℃. This result is expected to be used as primary data for designing a freezing desalination system that uses seawater, including the water discharged from a seawater heat pump. is 0.75hp, and seawater storage tank is 20L.
