Solar absorption refrigeration is an eco-friendly and sustainable cooling solution that harnesses the power of the sun to provide cooling without relying on electricity or harmful.
2. Solar refrigeration technology Solar refrigeration offers a wide variety of cooling techniques powered by solar collector-based thermally driven cycles and photovoltaic (PV)-based electrical cooling systems. Fig. 1 shows a schematic diagram of a solar thermal cooling system.
Solar collector absorption refrigerators employ a combination of water and lithium bromide (water- LiBr). With the decline of traditional energy sources and the rise of environmental contamination in the future, solar refrigeration systems will become increasingly popular.
Proper sizing is essential to ensure the system operates efficiently and meets the cooling demand. The absorption chiller is the heart of the solar absorption refrigeration system. It uses the heat collected by the solar collector to drive the refrigeration cycle, providing the desired cooling effect.
The refrigerant, typically water, evaporates at low pressure and absorbs heat from the surrounding environment. The absorbent, usually a salt solution like lithium bromide or ammonia, captures the refrigerant vapor, creating a solution. This solution is then heated by the solar collector, separating the refrigerant vapor from the absorbent.
Schematic of solar resorption cooling system. In this case, in generator, the refrigerant is also separated from the absorbent by the heat provided by the solar collector, but vapour-refrigerant are reabsorbed by a weak-solution from resorber Rb and the system operates similarly to the above mentioned cycle.
In their system, thermal energy produced by the solar collector was stored in a 2.5 m 3 hot-water storage tank. Their experimental results during the summer period showed that the cooling capacity was 6.5 kW. The measured COP of the absorption system was in range of 0.4–0.8 at the generator temperature of 70 °C to 100 °C.

In these tubular or advanced collectors high performance is achieved by the use of the following advanced features: Highly efficient removal of the absorbed heat from the solar collector by the principle of heat pipe. These keywords were added by machine and not by the authors.
There are two main types of collectors: non-concentration and concentrating collectors. In non-concentration collectors, the collector area and absorber area are the same. These collectors intercept solar radiation and absorb it without concentrating it.
In a solar collector, the absorber is a fundamental functional part because it regulates the efficiency of energy conversion, from solar radiation to thermal energy.
Typical Air collectors or Solar Air Heater: A flat plate collector used for heating an air stream consists of a plate with attached fins on the back side to increase contact surface area. The back side of the collector is heavily insulated with materials like mineral wool.
The existing concentrating solar collectors are described below: Flat concentrator collectors: they are the simplest concentrator collectors because they are flat-plate collectors characterized by reflective plates connected with the head-on surface of the collector (see Fig. 7 a).
Evacuated tube solar collector (ETSC), also known as Vacuum tube collectors, is a collector made up of evacuated glass tubes, aluminum fins, and a heat pipe.
The vacuum tube solar collector consists of a set of cylindrical tubes. The tubes are made up of a selective absorber on a reflective seat and surrounded by a transparent glass cylinder. A vacuum has been created between the transparent outer tube and the inner absorber that acts as a diathermic wall.
Solar collectors are the key component of solar-heating systems. There are several types of solar collectors: A vacuum tube collector (Fig. 1) consists of a group of single vacuum tubes linked together to one collector. Built into each tube is a coated absorber made of copper or glass. The vacuum in the glass tubes ensures optimum heat insulation.
Evacuated tube solar collectors are categorized into two major groups; the single-walled glass evacuated tube and the Dewar tube (Gao et al., 2013).
In contrast to Viessmann flat-plate collectors, the absorber in vacuum tube collectors on solar thermal systems is located directly on the tubes themselves. In the former, the tubes through which the solar medium flows are located between two flat absorber layers. Another special feature is the vacuum.
The benefits of vacuum tube collectors versus flat solar collectors are explained below. Evacuated tube solar collectors are cheaper than flat solar collectors. Nowadays, the price has improved due to the growing demand, experience, and new tube manufacturing technologies.
Solar collectors aim to convert solar radiation into thermal energy reducing heat losses. The vacuum tube solar collector consists of a set of cylindrical tubes. The tubes are made up of a selective absorber on a reflective seat and surrounded by a transparent glass cylinder.
