| Abstract | ||
| In addition to the Temperature rising in the summer season, the large employment of the domestic refrigeration and air-conditioning equipment playing big role in increasing the peak load demands for the national electrical system and the usage of refrigeration and A/C systems consuming low energy (Low running cost) contribute in decreasing the peak load demands. As soon as the traditional direct expansion systems consume high energy, we suggest dual system composing refrigeration part as well as evaporative part consume less power than the traditional one, with respect to the same cooling effect . We studying the energy efficiency ratio (EER) for the suggested system ,the value of (EER) is (2.5) higher than that of the refrigeration part (1.8) and its less than that of evaporative part (12) . The Effectiveness of the dual system is (60-70)% its higher than the evaporative part (15-20)% and refrigeration part (40-42) %. | ||
