“…The solar COP of the system reached 0.14. In Germany, Bansal et al [93] developed a solar refrigerator with the capacity to produce a daily 4.4 MJ cooling effect operating with strontium chloride as the adsorbent and ammonia as the refrigerant. The maximum solar COP obtained was 0.08 with a daily solar radiation of 26 MJ/m 2 .…”

“…Such kind of tube collector has been widely applied in the solar engineering today. Bansal et al also studied the performance of some adsorption systems that used the vacuum tube as the bed [19] . Although such kind of bed possessed advantages mentioned above, there still remained problems to be solved, such as the low thermal utilization efficiency because of the heating medium, and the difficulty of the heat dissipation in the adsorption process.…”

The internal temperature change of an adsorbent bed, which is subjected to the solar insolation, has been numerically simulated. As the intensity of the solar radiation changes with the sun movement, the temperature distribution in the bed evolves continually. Based on the configuration of the evacuated tube bed, a two-dimensional model of heat transfer has been established and numerically solved. To identify the effect of the internal cooling mode, three kinds of thermal boundary condition have been applied to the cooling tunnel. The numerical results reveal that the uniform wall temperature condition presents the best cooling effect, while the natural air convection presents the worst effect. In addition, the temperature change of the bed with the bed diameter has been examined, incorporating with the effect of cooling channel size. For the cooling condition of the natural air convection, the sun-facing side of the bed not only warms up the most rapidly, but also shows the highest temperature. In contrast, the temperature rising of the sun-shading side is much less. The temperature difference between the sun-facing side and the sun-shading side can reach 70℃. The non-uniform distribution of the temperature of the bed will hinder the adsorption cooling performance.

The aim of this paper is to review the past achievements in the field of absorption systems, their potential and possible directions for future development. Various types of absorption systems and research on working fluids are discussed in detail. Among various applications, solar cooling and combined cooling, heating and power (CCHP) are identified as two most promising applications for further development of absorption machines. Under the same framework, special attention is given to the small capacity absorption machines and their current status at the market. Although this technology looks promising, it is still in development and many issues are open. With respect to that fact, this paper covers all the relevant aspects for further development of small capacity absorption machines
