In this study, performance assessment of absorption refrigeration cycle has been carried out under variable power sources namely electric, conventional fuel and renewable energy sources. The ammonia-water absorption cycle was used in this work, the temperatures at each point in the cycle such as generator, absorber, evaporator and condenser have been measured and with using absorption device system. The coefficient of performance and efficiency of the plant were measured and then compared. The results showed that when the cycle driven by electricity, the coefficient of performance varied 0.694 to 1.032 along the test time and the generator temperature changes from 48.1˚C to 101.5˚C with the average efficiency of 57.1% and average coefficient of performance of 0.78. When methane used as a fuel to generate power the coefficient of performance varied between 0.686 and 0.94 under the generator temperature of 123.3˚C and 127.4˚C and average efficiency of 40.02% with coefficient of performance of 0.735. Solar energy used as the alternative source of power which is the clean and safe power source and when the plant driven by the solar thermal energy, the coefficient of performance reached to 0.801 under the generator temperature of 91˚C, but the system efficiency about 11.68% along the test time. Solar energy can be used efficiently and replaced the conventional power sources to drive the absorption refrigeration unit.

“…According to Jakob et al [22], recent development activities on solar DAR (Diffusion Absorption Refrigerator) in Europe cover cooling capacities between 16 W and 2.5 kW and cycle COPs between 0.2 and 0.5. For development of continuous solar-driven refrigerators or heat pumps, single-effect ammonia machines have been the most frequently considered (Shiran et al, [23]; McLinden and Klein, [24]; Alvares and Trepp, [25]; Best, [26]; ARTISC, [27]). Ammonia absorption refrigeration system had been demonstrated at a winery in Graz, Austria (SACE Evaluation report, [28]).…”

“…They reported daily average collector efficiency of 49%, chiller COP 0.62 and solar fraction of 60.4%. Best and Ortega [10] summarized the results of Sonntlan Mexicali Solar Cooling Project from 1983 to 1986 in Mexico. The solar cooling system included six single-family houses, 316 m 2 flat plate collectors, 30 m 3 heat storage, a 90 kW ARKLA-WFB 300 Solaire LiBr-water chiller and a 200 kW cooling tower.…”

An environmental control system utilizing solar energy would generally be more costeective if it were used to provide both heating and cooling requirements in the building it serves. Various solar powered heating systems have been tested extensively, but solar powered air-conditioners have received little more than short-term demonstration attention. This paper reviews past eorts in the ®eld of solar powered air-conditioning systems with the absorption pair of lithium bromide and water. A number of attempts have been made by researchers to improve the performance of the solar applied air-conditioning (chiller) subsystems. It is seen that the generator inlet temperature of the chiller is the most important parameter in the design and fabrication of a solar powered air-conditioning system. While collector choice, system design and arrangement are other impacting factors for the system operation. 7
