“…It is found that the system COP increases with the increase of adsorption/desorption time and the effect of switching time is marginal. Moreover, numerous types of working pairs can be applied in various applications as reviewed by Goyal et al [9] besides Bataineh and Taamneh [10].…”

Adsorption refrigeration system (ARS) is regarded as one of promising clean technologies since it uses a low-grade thermal energy (solar energy, waste heat, etc.). The present paper provides a dynamic modeling of two-bed ARS with RD silica gel/water and SWS-1L/water as working pairs based on MATLAB program. The refrigeration capacity and coefficient of performance are calculated in terms of cycle time, hot water inlet temperature, cooling water inlet temperature, and chilled water inlet temperature. Simulation results indicated that the coefficient of performance increases linearly with adsorption/desorption time. Refrigeration capacity increases gradually until reaches an optimal adsorption/desorption time and then reduces. RD silica gel/water and SWS-1L/water pairs provides a refrigeration capacity of 11.7 kW and 4 kW, respectively at evaporator temperature of 10. Both working pairs are limited by the hot water inlet temperature of 95. The half cycle times are fixed to 350 and 280 s for RD silica gel/water and SWS-1L/water, respectively which selected based on optimum time which gives maximum cooling capacity, whereas the switching time for pre-cooling and pre-heating processes is set to 30 s for both working pairs.

“…In recent years, a great effort has been made in the development of solar-powered absorption machines in order to protect the environment: with various heating source temperatures [18], collecting recent improvements [19], applied to a hospital [20], with a warming impact assessment [21] and in Mediterranean climates [22]. The main advantage of solar cooling facilities is that the period of highest cooling demand coincides with that of highest solar radiation (summer).…”

A solar air-cooled high efficiency absorption system in dry hot climates: Reduction of water consumption and environmental impact

A solar cooling system with an optimized air-cooled double-effect water/LiBr absorption machine is proposed as a sustainable alternative to meet cooling demands in dry hot climates. This system allows eliminating the cooling towers in those regions of the planet where water is scarce. This work analyses the environmental benefits of this air-cooled system, as well as its environmental footprints, compared to a solar water-cooled single effect. In this regard, a methodology has been applied to calculate the annual saving in water consumption produced in a case study: a hospital located in Almería, in South of Spain. Furthermore, the reduction in energy consumption and CO 2 emissions is also quantified since this machine can be driven by solar energy and with higher efficiency than those of single effect.

The aim of this investigation is to evaluate the recent advances in the field of solar absorption cooling systems from the viewpoint of solar collector types. A review in the area of photovoltaic thermal (PVT) absorption cooling systems is conducted. This review includes experimental and computational work focusing on collector types and their efficiencies and performance indicators. Compared to vapour compression air conditioning systems, 50% of primary energy was saved by using solar absorption cooling systems and 10-35% maximum electrical efficiency of PVT was achieved. This review shows that Coefficient of Performance (COP) for solar cooling systems is in the range of 0.1-0.91 while the thermal collector efficiencies are in the range of 0.06-0.64. The average area to produce cooling for single effect absorption chillers for experimental and computational projects is 4.95 m 2 /kW c and 5.61 m 2 /kW c respectively. The specific area for flat plat collector (FPC) is in the range of 2.18-9.4 m 2 /kW c , while for evacuated tube collector (ETC) is in the range of 1.27-12.5 m 2 /kW c. For concentrated photovoltaic thermal collector (CPVT) and PVT, the average area to produce cooling for solar absorption chillers are 2.72 m 2 /kW c and 3.1 m 2 /kW c respectively.
