| Abstract: |
| Zones with high insolation need more cooling, and this need increases during the day by increasing solar radiation. This paper focuses on modeling a 50 W cooling capacity solar ammonia-water absorption refrigerator. The model is composed of two solar and chiller models. The solar model calculates the effects of collector area, overall collector thermal efficiency and radiation intensity variations during the day. The radiation model is based on clear sky Bird’s irradiation model validated with the normalized real data. The results indicate that because of the solar intensity variations, during a day, from 300 W/m2 to 900 W/m2 the refrigerator capacity and the generators temperature change. It is showed that an area of 0.58 m2 is required with an evaporator temperature of -10 oC to reach to a cooling capacity of a home refrigerator. |
