| Abstract | ||
| In this study, a design and fabrication of intermittent solar absorption refrigeration unit was performed at Hillah city in Iraq)32.4o, 44.4o). The absorption solar unit consists of parabolic trough concentrator (PTC) was used as solar rays mirror reflector with aperture area of 2 m2 , carbon steel pipe inside a vacuum glass envelop with a diameter of 1.5 in as tubular receiver, condenser, storage tank, evaporator. The aqua ammonia solution) NH4OH)is used as working fluid with different concentration (25%, 30%, 35%, 40%). The validity and visibility of the unit were evaluated by measurements of pressures and temperatures at different parts of the unit during a year from May month 2014 to July month 2015. The maximum pressure and temperature is found to be 12 bar and 120oC respectively. The coefficient of performance was in the range of 0.01-0.09. | ||
