“…The remaining solution (8) flows back to the absorber and, thus, completes the cycle. In order to improve system performance, the solution heat exchanger is included in the cycle [12][13][14][15][16][17][18][19][20]. Due to high efficiency at high temperature, the evacuated tube solar collector type has been chosen as it can provide good performance at the high temperature required by the absorption system as stated by Assilzadeh et al [21].…”

“…It is assumed for the calculation that the evacuated solar collector surface is placed with tilted angle of 23 0 degree and oriented to the south direction. The solar radiation production on collector surface area and the heat output from solar collectors can be determined using the Hottel-Whillier equation [12,30,31]:…”

“…Some studies have been done in this area and have been considered extensively, but the effect of the generator temperature in a solar powered single absorption refrigeration system by meteorological solar data for a house usage depending on the cooling need has not been considered in detail. Some of the studies are given [12][13][14][15][16][17] and cited therein.…”

Abstract. In this study, an absorption system using ammonia-water (NH 3 -H 2 O) solution has been theoretically examined in order to meet the cooling need of a detached building having 150 m 2 floor area for Antalya,Mersin and Mugla provinces in Turkey. Hourly dynamic cooling load capacities of the building were determined by using Radiant Time Series (RTS) method in the chosen cities. For the analysis, hourly average meteorological data such as atmospheric air temperature and solar radiation belonging to the years 1998-2008 are used for performance prediction of the proposed system. Thermodynamic relations for each component of absorption cooling system is explained and coefficients of performance of the system are calculated. The maximum daily total radiation data were calculated as 7173 W/m 2 day on July 15, 7277 W/m 2 day on July 19and 7231 W/m 2 day on July 19 for Mersin, Antalya and Mugla, respectively on the 23° toward to south oriented panels from horizontal surface. The generator operating temperatures are considered between 90-130°C and the best result for 110°C is found the optimum degree for maximum coefficient of performance (COP) values at the highest solar radiation occurred time during the considered days for each province. The COP values varies between 0.521 and 0.530 for the provinces. In addition, absorber and condenser capacities and thermal efficiency for the absorption cooling system were calculated. The necessary evacuated tube collector area for the different provinces were found in the range of 45 m 2 to 47 m 2 . It is shown that although the initial investment cost is higher for the proposed absorption cooling system, it is economically feasible because of its lower annual operation costs and can successfully be operated for the considered provinces.

“…In addition, they do not contribute emissions to the ozone depletion or to the global warming. Although absorption refrigeration systems seem to provide many advantages, their COP is too low and initial investment cost is very high [4,8]. The most important parameter is the performance of solar collectors in the design of absorption cooling machine.…”

In this study, performance analysis of solar-powered absorption refrigeration (SPAR) system is evaluated using hourly atmospheric air temperature and solar radiation data in Mersin city. Ammonia-water (NH 3 -H 2 O) as refrigerant-absorbent pair and evacuated tube solar collector are selected for the design of the SPAR system. First, hourly cooling loads of the selected building are calculated. Then, thermodynamic analysis of the SPAR system is conducted according to this cooling load and required solar collector area is calculated for the air-conditioned space. Obtained results show that the maximum coefficient of performance (COP) value is observed in May, while the lowest value is seen in July and August. When the maximum solar radiation rate is observed to be 0,878kW/m 2 on 23 June at 01:00 p.m., the COP is calculated as 0,434. Finally, the optimum collector area is determined to be 50 m 2 for air-conditioned space area of 30 m 2 .
