In the present study, cooling of a duplex house placed in Isparta province by using solar-powered single effect absorption refrigeration system, which uses water-lithium bromide (H 2 O-LiBr) mixture, was evaluated in details. Firstly, the cooling load of the house was determined as 19.34 kW. In order to provide the cooling load of the house (19.34 kW), the heat required for the generator was calculated as 26.76 kW, and the required collector surface area was determined by considering different types of collectors (flat plate and vacuum tube) to meet this heat capacity. In order to provide the cooling load of the house, the required surface area for the vacuum tube collectors was calculated as 10.32 m 2 while it was found as 25.95 m 2 for the flat plate collectors. It was concluded that the usage of vacuum tube collector with 57.9% efficiency is more appropriate since the required collector surface area is 15,63 m 2 less than the required collector surface area for flat plate collector.

“…But its design and operation are quite complex, and after a period of working time, the chemical stability of the refrigerant is decreased, so it is difficult to maintain a high vacuum system, leading to a decline in the efficiency of the system. 60 At the same time, the initial investment of absorption refrigeration is relatively large, which limits its development. These are the features of solar-powered LiBr absorption air-conditioning system.…”

Phase change material cold storage system could improve the efficiency and stability of the solar-powered airconditioning system and the building thermal environment. This article is a novel investigation of the phase change materials' usage in cold storage system and the phase change material cold storage working principles and features that are applied in the different solar-powered airconditioning systems as cited in the recent publications. This involves phase change material cold storage system, solar-powered airconditioning system, and the commercial market evaluation. To reduce the intermittent solar energy operation, the energy storage system is quite essential. Currently, the popular method is advanced phase change material cold storage. Using phase change materials in the energy storage systems, the heat exchangers and thermal control systems are the potential techniques. This article also reviewed the phase change material cold storage when applied in the solar-powered airconditioning system based on the previous study. This article could benefit further research in the solar-powered airconditioning field as integrated to the phase change material cold storage system and help to understand the commercial market development trend. For further studies, it was suggested that the optimal design of solar-powered cooling system could be employed by phase change material storage/release cooling dynamical control to improve the building thermal environment.

“…The most frequently used refrigerants in a conventional space cooling system are CFCs and HCFCs which are branded as ozonedepleting material [12,13]. Solar cooling is the best alternative to traditional refrigeration machines, and it has been studied in detail than other systems [5]. Best absorbent-refrigerant pairs should have an easy separation at high temperature, chemical steadiness, excellent refrigerant affinity at low temperature, low-toxicity.…”

Here, performance of 11 kW solar-powered lithium bromide water absorption chillers in cogeneration mode is investigated. A 40 m 2 solar parabolic dish of 19 kW th capacity is used for both processes heating and cooling. Extensive thermodynamic design and analysis are carried out, and the results obtained are validated. Parabolic dish and cavity receiver are sized for Chennai (13°N, 80.18°E), India. In the present analysis, a new performance parameter COP WE is introduced by replacing the thermal input component in the calculation of COP, by an equivalent amount of high-grade energy. Both physical and chemical exergy at all state points of the chiller are estimated and found that total irreversibility is about 2.37 kW in desorber followed by absorber which is 0.41 kW. The developed model estimates solution concentration at the exit of solution expansion valve (SEV) that is important since it affects absorption of refrigerant in the absorber.
