    Abstract

    Desalination unit based on heat pump with humidification and dehumidification processes is one of the applications of heat pump system, with addition of a humidifier, sprinkler and evaporator (as dehumidifier) that integrated in a duct. The air has humidified in the humidifier with the spray of seawater through the sprinkler and then it has cooled in the evaporator to produce fresh water. The addition of electric water heater has used to vary the seawater temperature to the humidifier on this system. In this research has examined the effect of preheating seawater temperature on the performance of desalination unit based on heat pump system with using humidification and dehumidification processes. In this research the seawater/feed water temperature has varied at 28oC, 30oC, 45oC and 60oC, air temperature has conditioned at a constant temperature of 30oC, and ambient temperature has kept constant at 28oC. Compressor has operated at a constant rotation of 1,200 rpm, the seawater volumetric flow rate has kept at 300 l/h, and seawater in this system has recirculated. The result of this research showed that the volume of fresh water production increase with increasing the inlet of the seawater/feed water temperature to the humidifier on this desalination unit. Keywords : desalination, heat pump, preheating, humidification, dehumidification
