Abstract: | ABSTRACT: A humidification/dehumidification (HDH) solar desalination unit having combined solar water/air heater was designed constructed and experimentally investigated. The main components of the desalination system are the combined solar air/water heater collector with double glazing, humidifier (evaporator), dehumidifier (condenser), circulating pump, fan and a storage tank. Both air and saline (or brackish water) were heated in a single combined solar water/air heater. The effect of air mass flow rate and the temperature difference of the brackish water between the solar collector and humidifier exits on the performance were investigated. The result showed that the temperature difference has no effect on the system productivity however; the change in the air mass flow rate has a direct effect on fresh water productivity.
The maximum productivity was achieved on 7th of July 7.2L/m2day at air mass flow rate of 0.0261 kg/s. Furthermore, economic study was provided and it is found that the cost of fresh water per liter was calculated as 0.041TL and the payback period was estimated to be 770 days.
Keywords: Solar desalination, Humidification, Dehumidification.

ÖZ: Kombine güneş su/hava ısıtıclı bir nemlendirme/nem alma (HDH) desalinasyon ünitesi tasarlanmış, yapılmış ve deneysel olarak incelenmiştir Desalinasyon sisteminin ana bileşenleri kombine çift cam güneş hava/su ısıtıcı kolektörü, nemlendirici (evaporatör), nem alıcı (kondenser), pompa, fan ve bir su tankıdır. Hava ve tuzlu su (veya acı su) kombine güneş su/hava ısıtıcısında ısıtılmıştır. Hava kütle akış hızının, güneş kolektörü ve nemlendirici çıkışındaki tuzlu su sıcaklıklarının sistem üretkenliğine etkileri incelenmiştir. Sonuç olarak, tuzlu sudaki sıcaklık farkının sistem verimliliği üzerinde hemen hemen hiçbir etkisinin olmadığını ancak; hava kütle akış oranındaki değişimin tatlı su verimliliği üzerinde doğrudan bir etkiye sahip olduğu gözlemlenmiştir. Maksimum verimlilik 0,0261 kg/s hava debisi ile 7 Temmuzda 7.2L/m2gün olarak elde edildi. Ayrıca, ekonomik çalışma sağlandı ve elde edilen tatlı su maliyetinin litre fiyatı 0.041TL olarak tesbit edildi sistemin kendisini geri ödeme süresi ise 770 gün olarak tahmin edilmiştir.
