摘要：

This study, which was carried out in a mild and wet region, designed and fabricated an indirect solar desalination system (double loops), to investigate effect of employing separate and combined insertion of twisted tape and wire coil turbulators in a spiral heat exchanger at diffrent mass rate of salty water on productivity of desalination in this system. After the presentation of the experiment data, the results are analyzed and discussed. In comparison to simple spiral tube heat exchanger, the insertion of the turbulators in a circular tube heat exchanger would enhance discharge rate between 2% to 14% in using Twisted Tape, and copmbined Twisted Tape & Wire Coil, respectively. In addition, simultaneous insertion of twisted tape and wire coil could increase the output to its maximum discharge. The best working conditions of this system was to put 1 lit/s mass rate of salty water. Productivity system increased up to 9.7% too.
